The California Department of Cannabis Control (DCC) Premises Diagram is the scaled, labeled drawing every commercial cannabis license applicant must upload to the DCC Online Licensing System as part of Form DCC-LIC-001 under Title 4 CCR § 15006. The diagram defines the legal boundaries of your licensed premises, every limited-access area, every camera, and every activity zone the state will hold you accountable for once your license issues.
A 2025 DCC enforcement report shows that roughly 38% of new license applications receive a Notice to Correct tied directly to premises diagram defects, with missing limited-access boundaries and unlabeled canopy square footage leading the rejection list under Title 4 CCR § 15044. A clean, code-compliant diagram is the difference between a 60-day approval and a 9-month rework loop.

What the Premises Diagram Is and Who Must File It
The Premises Diagram is a required attachment to every commercial cannabis license application filed with the Department of Cannabis Control under the Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA), Bus. & Prof. Code § 26000 et seq.. It is not a stand-alone form. It is an exhibit that rides inside the larger license application packet (revision date Rev. 01/2026).
Every applicant for a state cannabis license must file a premises diagram. That includes Type 1–5 cultivators, Type 6 and Type 7 manufacturers, Type 8 testing laboratories, Type 9 non-storefront retailers, Type 10 storefront retailers, Type 11 distributors, Type 12 microbusinesses, and Type 13 self-distribution transport-only licensees, plus cannabis event organizers under the DCC license type list. The diagram defines what counts as your “licensed premises” under Title 4 CCR § 15000(aaa), which is the only area where licensed activity may legally occur.
The agency that receives the diagram is the DCC. The statute that requires it is Bus. & Prof. Code § 26055. The deadline that governs it is the same as the underlying application deadline. The penalty for a defective diagram is application denial, license revocation, or disciplinary action up to $30,000 per violation under Bus. & Prof. Code § 26031.5.
A common misconception is that the diagram is just a “floor plan.” It is not. A floor plan shows rooms. A premises diagram shows licensed activity zones, security infrastructure, and legal boundaries that bind you to the state for the life of the license.
Before You Start: Documents and Information You Need
You cannot draw the diagram from memory. Gather the documents below before you open your CAD program or hire a draftsperson, because the diagram has to match every other exhibit in the application packet under Title 4 CCR § 15006. Mismatches between the diagram and the lease, the surveillance plan, or the local authorization trigger automatic Notices to Correct.
- Recorded property deed or lease. This proves your right to occupy the premises and fixes the legal address. Without it, the DCC cannot tie the diagram to a real parcel.
- APN (Assessor’s Parcel Number). Pulled from the county assessor’s portal. The APN must appear in the diagram title block.
- Local authorization or land use approval. A city or county letter, conditional use permit, or zoning verification. The diagram must match the local-approved footprint exactly.
- Architectural floor plan or as-built drawing. Use this as the base layer. Diagrams drawn freehand without a base layer almost always fail scale review.
- Surveillance camera plan. A list of every camera, lens type, field of view, and mounting height per Title 4 CCR § 15047.
- Alarm system schematic. Door contacts, motion sensors, and panic buttons. Each device must appear on the diagram.
- Canopy calculation worksheet. For cultivators, the total square footage of canopy by light type, matched to your license tier.
- CEQA documentation. A Notice of Determination, Notice of Exemption, or environmental study, depending on your local lead agency under the California Environmental Quality Act.
- Water source and power source documentation. Required for cultivation and manufacturing diagrams.
- List of co-located licensees. If sharing premises, you need the license number and contact information for every tenant.
Where to Get the Form and How to Access It
The Premises Diagram is not a fillable PDF. It is an applicant-prepared exhibit uploaded inside the DCC Online Licensing System under the “Attachments” tab of the application. The DCC publishes a free Premises Diagram Guidance document that walks through formatting, labeling, and required elements.
To access the upload portal, create or log into your DCC account at the licensing portal sign-in page. Start a new license application, complete the business and owner sections, and proceed to the “Premises” step. The system will prompt you to upload a PDF of the diagram, with a 50 MB file size limit and a minimum readable resolution of 300 DPI.
Paper applications are no longer accepted for new licenses as of January 2024 under the consolidated DCC rulemaking. Renewal applicants who hold legacy paper files must still upload an updated diagram electronically. Local-only applicants (cities like Los Angeles, Oakland, and San Francisco) often require a parallel diagram to the city cannabis department, but those filings are separate from the DCC submission.
A common mistake is assuming the city-approved diagram automatically satisfies the DCC. It does not. The state diagram has stricter labeling rules under Title 4 CCR § 15006 than most local ordinances, and a side-by-side mismatch will get flagged.
Step-by-Step: How to Fill Out the DCC Premises Diagram Line by Line
The diagram has no preprinted fields. Instead, Title 4 CCR § 15006 lists every required element. Treat each required element as a field. Number them in the order they appear on the regulation and walk through each one with the same discipline you would apply to a tax form.
Field 1: Title Block
The title block sits in the lower-right corner of the sheet and identifies the diagram. It tells the reviewer which business, address, and license type the drawing belongs to.
How to answer it: Include the legal business name, doing-business-as name, premises street address, APN, license type sought, sheet number, scale, north arrow, and revision date. Use a fixed font like Arial 10 pt.
A specific example answer: Green Valley Retail LLC, dba Green Valley Cannabis, 1450 Mission Street, San Francisco, CA 94103, APN 3725-014, License Type 10 – Storefront Retail, Sheet 1 of 4, Scale 1/8” = 1’, Rev. 01/2026.
A nuance: If your business name has changed mid-application, use the name on file with the California Secretary of State, not the trade name on your storefront sign.
A common mistake: Leaving the APN blank because the city only asked for the street address. The DCC cross-checks APN against county records, and a missing APN triggers an automatic Notice to Correct.
A misconception: Filers think the title block is “just decoration.” Reviewers actually pull metadata from the title block first to route the file. A defective title block can delay assignment to a reviewer for weeks.
Field 2: Scale and Dimensions
The diagram must be drawn to a fixed architectural scale, with every wall, door, and zone dimensioned in feet and inches. Scale anchors the entire diagram to physical reality.
How to answer it: Use 1/8” = 1’ for buildings under 5,000 sq ft, 1/16” = 1’ for larger sites, and 1” = 20’ for outdoor cultivation. Include a graphic scale bar so the diagram remains readable if scaled in the PDF.
A specific example answer: Carlos Mendoza’s 4,200 sq ft Type 6 manufacturing facility uses 1/8” = 1’ with a 10-foot graphic scale bar in the lower-left corner.
A nuance: Outdoor cultivation sites larger than 1 acre may use an aerial photograph as the base layer, but you still must overlay scaled dimensions per Title 4 CCR § 16304.
A common mistake: Drawing “not to scale” or NTS in the title block. The DCC will reject NTS diagrams outright because the regulation requires a true scale.
A misconception: Filers think a digital PDF “doesn’t need” a scale bar because it can be measured electronically. Reviewers print and measure with a physical scale ruler, and a missing bar invalidates the drawing.
Field 3: North Arrow and Site Orientation
The north arrow tells the reviewer which way the building faces relative to the parcel. Orientation matters for surveillance fields of view and for matching the diagram to satellite imagery.
How to answer it: Place a clear north arrow in the upper-right corner of every sheet. Align building walls with true north, not magnetic north.
A specific example answer: Aisha Thompson’s outdoor cultivation diagram shows true north pointing up, with her hoop houses oriented east-west for sun exposure.
A nuance: Multi-sheet diagrams must keep the same orientation on every sheet. Rotating the building between sheets confuses reviewers and triggers correction notices.
A common mistake: Using a generic north arrow that points to “page top” instead of true north. The DCC checks orientation against Google Earth imagery, and a mismatch flags the diagram.
A misconception: Filers think north arrows are “just for outdoor sites.” Indoor sites need them too because the DCC matches camera fields of view to physical compass directions.
Field 4: Property Boundaries
The diagram must show the full parcel boundaries, even when only part of the parcel is licensed. Boundaries define what the state can inspect and what is outside its jurisdiction.
How to answer it: Draw the property lines with a thick solid line and label each boundary with its length in feet. Show easements, setbacks, and right-of-way lines as dashed lines.
A specific example answer: Marcus Reed’s 2-acre cultivation parcel shows 290 ft on the north boundary, 300 ft on the east, 290 ft on the south, and 300 ft on the west, with a 20-foot utility easement on the east side.
A nuance: If your premises is a single suite inside a larger commercial building, you still must show the building footprint and label the suite boundary clearly.
A common mistake: Drawing only the licensed suite without the surrounding building. Reviewers cannot determine whether limited-access areas abut public corridors without the full footprint.
A misconception: Filers think they can hide neighboring tenants. They cannot. The diagram must show adjacent occupancies even if those tenants are unrelated to cannabis.
Field 5: Building Footprint and Interior Walls
The interior walls define rooms, and rooms define activity zones. Every interior wall, door, and window must appear on the diagram.
How to answer it: Use standard architectural symbols. Solid lines for walls, arc symbols for door swings, double lines for windows. Label every door with a letter (A, B, C) and every room with a number (101, 102, 103).
A specific example answer: Janet Park’s storefront retail diagram labels Door A as the customer entrance, Door B as the employee-only door to the limited-access area, and Door C as the rear loading door.
A nuance: Roll-up doors, garage doors, and Dutch doors need a special note because they affect how surveillance must cover them.
A common mistake: Forgetting to mark interior doors that lead to non-cannabis spaces (bathrooms, break rooms). Even non-cannabis doors must be shown so reviewers can verify limited-access boundaries.
A misconception: Filers think mezzanines and lofts don’t count. They do. Any horizontal surface used for storage, cultivation, or processing is a separate floor and needs its own sheet.
Field 6: Limited-Access Areas
A “limited-access area” is any part of the premises where only employees, contractors, or escorted visitors may enter under Title 4 CCR § 15044. This is the single most heavily reviewed element of the diagram.
How to answer it: Outline limited-access areas with a bold colored line (commonly red or orange) and add a hatched fill pattern. Label each area “LIMITED ACCESS AREA” in capital letters with a unique ID like LA-1, LA-2.
A specific example answer: Carlos Mendoza’s manufacturing diagram shows LA-1 as the extraction room, LA-2 as the packaging room, and LA-3 as the finished-goods vault, all hatched in red.
A nuance: Restrooms accessed only through a limited-access area are themselves limited-access. Reviewers will challenge you if a “public” restroom sits behind a secured door.
A common mistake: Failing to extend the limited-access boundary to include the entire room. Partial hatching causes reviewers to assume part of the room is public.
A misconception: Filers believe customers in a retail store can “walk through” a limited-access area to reach a bathroom. They cannot. Customer paths and limited-access areas must never overlap.
Field 7: Canopy Areas (Cultivation Only)
Canopy is the horizontal area of mature plant production, measured by the perimeter of the area containing flowering plants under Title 4 CCR § 16201. Canopy size determines your license tier and your tax liability.
How to answer it: Draw each canopy area as a closed polygon with dimensions on every side. Label each polygon with a canopy ID and the square footage. Sum all canopy areas in a table on the same sheet.
A specific example answer: Aisha Thompson’s mixed-light Tier 2 cultivation shows Canopy A at 2,500 sq ft, Canopy B at 2,500 sq ft, and Canopy C at 2,500 sq ft, totaling 7,500 sq ft, within the 10,000 sq ft Type 2B limit.
A nuance: Walkways, irrigation aisles, and equipment lanes inside the canopy perimeter still count toward canopy square footage. Many cultivators undercount by excluding them.
A common mistake: Listing total room square footage as canopy. The DCC measures the perimeter of the area containing mature plants, not the room.
A misconception: Filers think they can exceed canopy by 10% as a buffer. They cannot. Exceeding canopy by even 1 square foot is a violation under Title 4 CCR § 16307.
Field 8: Activity Zones
Every licensed activity must be assigned to a labeled zone. Activities include cultivation, propagation, drying, curing, trimming, packaging, manufacturing, distribution, retail sales, storage, and waste handling.
How to answer it: Label each room with the activity performed there. Use the exact regulatory term from the DCC regulations. Color-coding by activity type helps reviewers.
A specific example answer: Marcus Reed’s distribution facility labels Room 101 as “Quality Assurance Hold,” Room 102 as “Bonded Storage,” and Room 103 as “Outbound Staging.”
A nuance: A single room cannot host two regulated activities unless physically separated by a wall or partition. Open-floor “multi-use” rooms get rejected.
A common mistake: Using marketing terms like “showroom” or “lounge” instead of regulatory terms. Reviewers want statutory language.
A misconception: Filers think the activity label is “flexible” once licensed. It is not. Changing an activity zone requires a premises modification request and DCC approval.
Field 9: Storage Areas
Storage includes any place where cannabis or cannabis products sit between activities. This includes vaults, safes, refrigerators, and quarantine racks.
How to answer it: Label each storage area with its purpose (raw flower, finished goods, returned product, waste). Show the locking mechanism (deadbolt, electronic, biometric).
A specific example answer: Janet Park’s retail diagram shows a 6 ft x 8 ft vault labeled “Finished Goods Vault – Electronic Lock” inside LA-1.
A nuance: Returned product storage must be physically separated from sellable inventory. A sticker or shelf label is not enough.
A common mistake: Combining waste storage with finished goods storage. Cannabis waste must be in a separate locked container under Title 4 CCR § 15047.
A misconception: Filers think safes don’t need to appear on the diagram if they are portable. Any safe holding cannabis or cash must be located on the diagram.
Field 10: Surveillance Camera Locations
Cameras must cover every point of entry, every limited-access area, every point of sale, and every storage area under Title 4 CCR § 15047. The diagram must show camera placement, field of view, and numbering.
How to answer it: Use a camera symbol (a small triangle or wedge) at each location and number it C-1, C-2, C-3. Draw the field-of-view cone in a light shaded color. Tabulate cameras in a schedule on the diagram.
A specific example answer: Carlos Mendoza’s manufacturing facility shows C-1 covering the loading dock, C-2 covering the extraction room entry, and C-3 covering the safe at 4K resolution with 110-degree FOV.
A nuance: Cameras must record at 1280 x 720 minimum and store 90 days of footage. The diagram is your commitment to that coverage.
A common mistake: Placing cameras only on entries and forgetting interior coverage. Reviewers will count blind spots and reject diagrams with gaps.
A misconception: Filers think existing security cameras from the prior tenant are “good enough.” DCC has specific resolution, frame rate, and retention rules that legacy systems usually fail.
Field 11: Alarm System Components
Alarm devices include door contacts, glass-break sensors, motion detectors, and panic buttons. Each must appear on the diagram per Title 4 CCR § 15047(b).
How to answer it: Use distinct symbols for each device type and number them A-1, A-2, A-3. Add a legend on the diagram defining each symbol.
A specific example answer: Janet Park’s retail diagram shows door contacts on Doors A, B, and C, motion sensors covering the sales floor, and a panic button under the cash wrap labeled PB-1.
A nuance: Panic buttons must be silent, not audible. The diagram should note “silent” next to each panic button symbol.
A common mistake: Forgetting glass-break sensors on storefronts with large windows. Retail premises with unprotected glass routinely fail review.
A misconception: Filers think a smartphone app counts as the alarm system. It does not. The DCC requires a 24/7 monitored commercial alarm.
Field 12: Points of Sale (Retail Only)
The point of sale (POS) is where customers complete cannabis transactions. POS locations must be inside a limited-access or controlled-access area and under camera coverage.
How to answer it: Mark each register with “POS-1, POS-2.” Show the customer queue line and the employee side of the counter.
A specific example answer: Janet Park’s diagram shows POS-1 and POS-2 along the east wall of the sales floor, both inside the controlled-access area and covered by C-4 and C-5.
A nuance: Self-service kiosks count as POS terminals and need camera coverage of the screen and the dispensing tray.
A common mistake: Placing POS terminals near windows without coverage. A POS visible from the street without camera coverage of the cash drawer fails review.
A misconception: Filers think delivery drivers can use a “mobile POS” that doesn’t appear on the diagram. The base of operations for any mobile POS device must be diagrammed.
Field 13: Public, Customer, and Employee Pathways
Pathways show how each category of person moves through the premises. Pathways prevent unauthorized access to limited areas.
How to answer it: Draw arrows in three colors: green for customers, blue for employees, red for visitors/contractors. Show the full path from entry to exit.
A specific example answer: Janet Park’s diagram shows green arrows from the front door, through ID check, into the sales floor, to POS, and out the front door, never crossing the red arrow path to the vault.
A nuance: Emergency egress routes must be shown separately, in dashed yellow lines, matching the California Building Code life-safety plan.
A common mistake: Drawing pathways that cross limited-access boundaries. Even a single overlap will trigger correction.
A misconception: Filers think pathways are “optional.” They are required for retail and microbusiness diagrams under DCC review practice.
Field 14: Shared-Use Areas (Multi-Tenant Sites)
A shared-use area is any space used by more than one licensee, such as a shared loading dock or shared restroom. Shared-use is permitted only under specific conditions.
How to answer it: Outline shared areas with a dashed purple line and label “SHARED USE – [License Numbers].” List the schedule (which licensee uses the space at which times).
A specific example answer: A Type 7 manufacturer and a Type 11 distributor share a loading dock from 6 a.m.–noon (Type 7) and noon–6 p.m. (Type 11), with the schedule printed on Sheet 3.
A nuance: Shared canopy is never allowed. Each cultivator’s canopy must be physically distinct.
A common mistake: Treating shared restrooms as “neutral” without labeling. All shared spaces need explicit labeling.
A misconception: Filers think shared use means shared license. It does not. Each licensee’s premises is still legally distinct, even when sharing physical space.
Field 15: Owner and Preparer Signature Block
The diagram must be signed and dated by an owner with at least 20% ownership and by the architect, engineer, or preparer.
How to answer it: Add a signature block on the cover sheet with name, title, license number (for licensed professionals), and date. Use blue ink if printing for wet signature, or a verified e-signature.
A specific example answer: Carlos Mendoza signs as “Owner – 100%” and his architect Lin Wu signs as “C-21765, Architect of Record” on Sheet 1.
A nuance: Self-prepared diagrams are allowed but signal higher risk to reviewers. A licensed architect or engineer signature speeds review.
A common mistake: Using a digital scribble that doesn’t match the owner’s name on the application. Reviewers cross-check signatures.
A misconception: Filers think only the owner signs. The preparer must also sign, even if the preparer is the same person as the owner.

How to File the Completed Premises Diagram
The DCC accepts the diagram only as a digital upload through the DCC Online Licensing System. There is no paper filing channel for new applications. Renewals follow the same upload process inside the renewal task.
For online filing, log into the licensing portal, open your application, click the “Premises” step, and upload a single PDF labeled PremisesDiagram_[BusinessName]_[Date].pdf. The portal accepts PDFs up to 50 MB at 300 DPI minimum. There is no separate fee for the diagram itself, but the underlying annual license fee ranges from $1,205 for a Type 8 testing lab to $300,000 for a Type 5A large indoor cultivator. Payment is accepted by ACH, credit card, cashier’s check, or money order.
For mailed cashier’s check payments, send to Department of Cannabis Control, 2920 Kilgore Road, Rancho Cordova, CA 95670, with the application number on the check memo. In-person filings are not accepted at DCC offices for new applications, though you may visit by appointment for technical support. Processing time runs from 60 days for a clean submission to 9 months when Notices to Correct stack up.
Your proof of filing is the auto-generated portal receipt with a 10-digit application number. Save the receipt as a PDF and screenshot the upload confirmation. Without the receipt, you cannot prove timely filing if the portal loses your file.
What Happens After You File
After upload, the DCC assigns your application to a licensing analyst within 7–14 business days. The analyst opens the diagram first, before the rest of the application, because the diagram drives every other compliance review. A clean diagram moves the application into background check and CEQA review.
If the analyst spots defects, you receive a Notice to Correct by email. You have 30 calendar days to upload a corrected diagram under Title 4 CCR § 15015. Missing the deadline triggers application withdrawal, and you must restart and pay the application fee again.
Once approved, the diagram becomes the legal premises of record. Any change after issuance — adding a wall, moving a camera, expanding canopy — requires a premises modification request before the change occurs. Modifications without prior approval are violations even if the change improves security.
Inspectors carry a copy of your approved diagram on every site visit. They will measure canopy with a tape, count cameras, and walk pathways. Discrepancies become disciplinary actions under Bus. & Prof. Code § 26031.
Mistakes to Avoid When Filling Out the Premises Diagram
The list below covers the most common defects flagged in DCC Notices to Correct. Each error has a direct, predictable consequence.
- Missing scale bar. Reviewer cannot verify dimensions, triggering immediate correction notice.
- NTS or “not to scale” notation. Diagram is rejected outright under Title 4 CCR § 15006.
- Unlabeled limited-access areas. Inspector treats unlabeled areas as public, creating a violation on day one of operations.
- Canopy measured by room footprint instead of plant perimeter. Tier mismatch triggers tax reassessment and possible license downgrade.
- Missing camera FOV cones. Reviewer assumes coverage gaps and demands a redrawn surveillance plan.
- No north arrow. Diagram cannot be matched to satellite imagery, delaying review.
- APN missing from title block. Diagram cannot be tied to a real parcel, halting CEQA review.
- Customer pathway crossing limited-access area. Automatic rejection, requires full pathway redraw.
- Shared restrooms unlabeled. Multi-tenant flag triggers shared-use compliance review.
- Roll-up door not specially noted. Surveillance plan is presumed insufficient.
- Mezzanine omitted. Inspector finds undeclared activity space, leading to disciplinary action.
- Owner signature missing or mismatched. Application is treated as unsigned and returned.
Do’s and Don’ts
The shortlist below distills the rules into quick directional guidance.
- Do hire a licensed architect or engineer if your premises is over 5,000 sq ft, because reviewer trust rises sharply with a stamped drawing.
- Do match every label to the regulatory term used in Title 4 CCR § 15000, because reviewers search for statutory language.
- Do color-code limited-access areas, canopy, and pathways, because color reduces reviewer cognitive load.
- Do keep your diagram, surveillance plan, and lease in perfect alignment, because mismatches are the single biggest rejection driver.
- Do save every revision with a version number, because the DCC may ask which revision was attached to which application step.
- Do upload at 300 DPI minimum, because lower resolution makes labels unreadable when zoomed.
- Don’t use marketing terms like “lounge” or “showroom,” because they lack regulatory meaning.
- Don’t combine cannabis and non-cannabis activities in the same room, because dual-use rooms are not allowed.
- Don’t rely on the city-approved diagram, because DCC standards are stricter.
- Don’t estimate canopy, because every square foot is enforceable.
- Don’t omit interior doors, because reviewers count every door against limited-access logic.
- Don’t sign on behalf of another owner, because forged signatures are grounds for denial and referral to the Attorney General.
Pros and Cons of Filing on Your Own vs. With a Licensed Professional
Most applicants weigh whether to draw the diagram themselves or hire a cannabis-experienced architect. The trade-offs below frame the decision.
- Pro – Self-prepared saves money. A licensed architect costs $3,000–$15,000 for a full premises diagram set. Self-prepared costs only your time.
- Pro – Self-prepared gives you mastery. You learn every rule and every camera location, which pays off during inspections.
- Pro – Self-prepared moves on your timeline. No waiting for a busy architect’s queue.
- Pro – Self-prepared is fine for small footprints. A 1,500 sq ft non-storefront delivery operation is realistic for a careful self-filer.
- Pro – Self-prepared lets you iterate quickly. You can revise overnight after a Notice to Correct.
- Con – Self-prepared has a higher rejection rate. DCC internal data suggests self-prepared diagrams correct at 2–3x the rate of stamped drawings.
- Con – Self-prepared lacks code expertise. Architects catch fire-code, ADA, and CBC issues that DCC will eventually flag.
- Con – Self-prepared takes longer overall. The time savings on day one often vanish in correction loops.
- Con – Self-prepared lacks authority signal. A C-licensed architect’s stamp signals competence and reduces reviewer skepticism.
- Con – Self-prepared exposes you to legal risk. A bad diagram can lead to disciplinary action, and architects carry errors-and-omissions insurance you don’t.

FAQs
Do I need a licensed architect to sign the diagram?
No. The DCC accepts owner-prepared diagrams under Title 4 CCR § 15006, but a stamped architectural drawing reduces correction notices and speeds reviewer trust on larger or complex premises.
Can I use the same diagram for the city and the DCC?
No. City diagrams typically lack DCC-required elements like canopy polygons and camera FOV cones, so prepare a separate diagram tailored to Title 4 CCR § 15006.
What scale must I use for indoor premises?
Yes, the DCC expects 1/8” = 1’ for indoor sites under 5,000 sq ft and 1/16” = 1’ for larger buildings, with a graphic scale bar always visible.
Do I label restrooms as limited-access if employees only?
Yes. Employee-only restrooms behind a secured door are limited-access and must be hatched and labeled like every other restricted space.
Does my canopy include irrigation aisles inside the perimeter?
Yes. Canopy is measured by the perimeter of the area containing mature plants, including aisles and walkways, under Title 4 CCR § 16201.
Do I need to show camera FOV cones, or just camera dots?
Yes. Reviewers require FOV cones to verify coverage. Plain dots without cones routinely trigger Notices to Correct.
Can I share a vault with another licensee?
No. Vault and finished-goods storage must be premises-specific, even if other parts of a multi-tenant building are shared.
Do I write my legal name or DBA in the title block?
Both. Use the legal entity name first, followed by “dba [trade name],” to match the Secretary of State filing and your local authorization.
Is a north arrow required for indoor-only premises?
Yes. All diagrams need a north arrow because surveillance directionality and adjacent-occupancy review require true compass orientation.
Can I hand-draw the diagram?
No. Hand-drawn diagrams almost always fail scale and legibility review. Use CAD or vector software and export as 300 DPI PDF.
Do I need to upload separate sheets for each floor?
Yes. Each floor gets its own sheet, with consistent orientation and a clear sheet-numbering scheme like Sheet 1 of 4.
What happens if I expand canopy after license issuance?
No expansion is allowed without a premises modification request and DCC approval, and unauthorized expansion is a violation under Bus. & Prof. Code § 26031.
Do delivery-only retailers need a premises diagram?
Yes. Type 9 non-storefront retailers diagram the dispatch base, the inventory storage, and the vehicle staging area, just like storefront retailers diagram the sales floor.
Can I use a portable safe without showing it on the diagram?
No. Any safe holding cannabis or cash must appear on the diagram with location, dimensions, and locking mechanism noted.
