San Diego sign permit at a glance

Question	Short answer
Do I need a permit?	Yes, a separate sign permit to install or alter any sign, except listed cases such as interior signs, window signs, temporary onsite banners, and unlit nameplates of no more than four square feet (Information Bulletin 111). Other cities compared.
What sets my wall-sign limit?	Your street wall length times a factor set by the width of the public right-of-way in front of you; ground, projecting and roof signs use right-of-way width and street speed limit (calculator).
Which sign category am I?	Category A: commercial and industrial zones generally. Category B: all CO and IP zones. Category C: all CN zones, and any commercial or industrial zone inside the Coastal Overlay Zone.
What are the wall-sign caps?	350 sq ft in Category A only where the premises has wall signs and no roof or projecting signs (otherwise 200 sq ft); 200 sq ft in Category B; 100 sq ft in Category C (all CN zones, and the Coastal Overlay Zone) (category limits). Other cities compared.
Ground signs?	Maximum 200 sq ft at the top of the Category A grid, 150 sq ft in Category B, 100 sq ft in Category C. Other cities compared.
Sign permit or Building Permit?	DSD lists four conditions where you submit a Building Permit instead, such as structural alterations to an existing building (how to apply).
What does it cost?	$793.95 plan check for one non-electric awning or wall sign; electric signs add an inspection fee (fee table).
How long does it take?	San Diego publishes no guaranteed turnaround (timing). Other cities compared.
Only swapping the sign face?	No separate sign permit is needed to change the copy, or for maintenance that does not involve structural or electrical changes (Information Bulletin 111). Other cities compared.
Window signs?	Window signs are on the city’s list of installations that need no separate sign permit (Information Bulletin 111). Other cities compared.
Grand opening banner?	Temporary onsite banners, streamers and pennants are on the city’s list of installations that need no separate sign permit (Information Bulletin 111). Other cities compared.
Who files?	The record owner of the property, the owner’s authorized agent, or another person with a legal right to use the property (§129.0805, §112.0102). Other cities compared.
When does the permit run out?	It becomes void 24 months after issue. Before then the city may extend it, for no more than 180 calendar days at a time and no more than two times, if circumstances beyond your control prevented completion (§129.0813–0814). Other cities compared.
Historic district?	A historic review may be required if the site has a designated historic resource, is within a designated historic district, or contains a structure 45 years or older (sign permit page; Information Bulletin 581). Other cities compared.
Digital or LED sign?	Changeable copy may not be changed remotely or electronically, except public service messages, gasoline price signs, and signs with automatic changing copy allowed with a Neighborhood Use Permit (§142.1210, §141.1105). Other cities compared.

Work out your San Diego sign allowance

San Diego Municipal Code Division 12 sets the wall sign from your street wall and the width of the street (Table 142-12C), and the ground, projecting and roof signs from street width and speed limit (Tables 142-12D, 142-12F, 142-12H). Enter one street frontage at a time; each frontage is calculated separately.

Sign category of your zone

§142.1220(b)(1). Planned districts, La Jolla (§142.1290) and Ocean Beach (§142.1291) follow other rules and are not covered.

Public right-of-way width in front of the frontage

Footnote 1 to Table 142-12C and footnote 2 to Tables 142-12D and 142-12F. Table 142-12C prints exactly 60 ft in both rows; ask Development Services which applies if your street is exactly 60 ft. Alleys and unimproved rights-of-way do not count (§142.1220(d)).

Street speed limit

Signs you plan on this frontage

Matters in Category A only: adding a roof or projecting sign lowers the wall factor and the 350 sq ft cap.

Length of your establishment's street wall (ft)

Height of that street wall (ft)

Used only for the minimum allowance, which is 25 percent of the street wall's area when that is smaller than 75 or 20 sq ft.

Street frontage of the premises on this street (ft)

Planned wall sign copy area (sq ft, optional)

Calculated from San Diego Municipal Code §142.1225 (Table 142-12C), §142.1230 (Table 142-12D), §142.1235 (Table 142-12F) and §142.1240 (Table 142-12H), Chapter 14, Article 2, Division 12, 9-2026 edition, read 10 October 2026. The wall figure is the table product, raised to the per-establishment minimum and limited to the category maximum; it is the total for all establishments sharing that portion of the street wall (§142.1225(c)(1)). Projecting, roof and ground figures are per sign face; a sign with two or more faces may have twice that area in total.

San Diego sizes wall signs by your storefront and the street in front of it.

Under the San Diego Municipal Code (Chapter 14, Article 2, Division 12), the wall sign copy area is the length of your establishment's street wall multiplied by a factor set by the width of the public right-of-way in front of it (Table 142-12C), capped by your sign category. Ground, projecting and roof signs are read from a second grid that adds the street speed limit. That's why two identical storefronts on different streets get different allowances.

What you actually need to know first

Your wall-sign allowance is your street wall length times a factor set by the width of the public right-of-way in front of you. Ground, projecting and roof signs use a grid of right-of-way width and street speed limit. Here's what controls each and where the hard caps are.

Because the factor changes with the street (§142.1225(b)), you can't size your sign from your storefront length alone. Owners who also run a location on the Strip should read the Las Vegas sign rules, where the allowance is built from a different table again. You need:

Street wall length

The length of your establishment's wall facing the street. Each street frontage is calculated separately and the areas cannot be combined onto one wall (§142.1225(c)(2), (c)(4)).

Right-of-way width

The width of the public right-of-way fronting your premises — not your lot width. If the right-of-way is 60 feet or less but is designated a major street or primary arterial, the allowance is based on the 60-foot figure.

Street speed limit

The street speed limit on the fronting right-of-way sets the ground, projecting and roof sign areas (Tables 142-12D, 142-12F, 142-12H). It does not enter the wall sign calculation.

Sign type

Wall, ground, projecting, and roof signs each have separate rules and separate caps.

Source: San Diego Municipal Code §142.1210–142.1240 (9-2026 edition, read 10 October 2026). §142.1225(b): the wall sign copy area "is based on the length of the establishment’s street wall and the width of the adjacent public right-of-way."

What your sign category actually allows

Whatever the table gives you, these absolute ceilings and rules are confirmed in the code and in the City's own guidance. Use them as a sanity check:

Wall signs — a minimum of one per establishment, in all three categories. The 350 sq ft maximum copy area applies only in Category A, and only where the premises has wall signs and no roof or projecting signs. Add a roof or projecting sign and the Category A maximum becomes 200 sq ft. Category B is 200 sq ft, Category C is 100 sq ft (Table 142-12C).
Ground signs — maximum 200 sq ft at the top of the Category A grid, 150 sq ft in Category B, 100 sq ft in Category C. The 300 sq ft figure belongs to freeway-oriented ground signs only, and only in Category A (Table 142-12H).
The 100-foot frontage rule is a Category B rule, not a city-wide one. Footnote 6 to Table 142-12H sits on the Category B column of the "number of signs per street frontage" row: ground signs are not permitted on premises having less than 100 feet of street frontage. The general rule in §142.1240(a) is the opposite — one ground sign for each premises with accessible street frontage, regardless of street frontage length. Table 142-12B repeats the 100-foot minimum in the Category B cell only.
Roof signs exist only in Category A. §142.1235 permits them "only in sign category a", and Table 142-12F prints "not permitted" in both the Category B and Category C columns. Inside Category A the maximum is 100 sq ft, or 300 sq ft for a freeway-oriented roof sign.
Projecting signs — maximum 160 sq ft per sign face, and only in Category A on a right-of-way wider than 60 feet with a 50+ mph speed limit. Everywhere else in the grid the ceiling is 90 sq ft (Category A) or 60 sq ft (Categories B and C). Footnote 1 to Table 142-12D doubles the permitted area where a sign has two or more faces. In Category A one projecting sign is permitted per establishment; in Categories B and C one is permitted per single-establishment premises having less than 100 feet in street frontage.
Flashing copy or lights, stroboscopic, intermittent and chasing lights, and alternating messages are not permitted (§142.1210(a)(5)–(6)). Animated copy is allowed if the animated portion is 10 sq ft or less, with a constant light source, and it counts toward your sign allowance (§142.1210(a)(7)).
On-premises sign copy must be removed within 30 calendar days after the business vacates (§142.1210(a)(9)).

The ordinance prints these cells as "32 sf", "50 sf" and so on; sf is square feet. Every area figure is for a single sign face — footnote 1 to Tables 142-12D, 142-12F and 142-12H doubles the permitted area where a sign has two or more faces, and no sign may exceed twice the maximum.

Coastal, historic, and planned districts change the rules again

San Diego layers additional sign rules on top of the citywide code in many areas — Coastal Program zones, planned districts (like the Mid-City Communities and beach-area planned districts), and historic districts each carry their own standards that can override the base §142 rules. If your storefront is near the coast or in a named district, the table allowance may not be the final word.

Two effects are written into Division 12 itself. Inside the Coastal Overlay Zone every commercial and industrial zone uses Sign Category C (§142.1220(b)(1)), which caps wall signs at 100 sq ft and allows no roof signs. Category A does not apply in planned districts, and La Jolla and Ocean Beach commercial zones have their own sections (§142.1290, §142.1291). The calculator at the top of this page does not cover planned districts, La Jolla or Ocean Beach.

How to apply for a San Diego sign permit — 9 steps

Your street wall and the street in front of it set your allowance in San Diego, and four DSD conditions decide whether you file a Building Permit instead.

1. Get the right-of-way width and the speed limit

Both are measured on the street your sign will face. The width sets your wall-sign factor; width and speed together set the ground, projecting and roof sign areas.

2. Find your sign category, then read the grid

San Diego does not give you one number. §142.1220(b)(1) sorts every commercial and industrial zone into Sign Category A, B, or C: Category A covers commercial and industrial zones generally, except where Table 142-12B precludes a sign type, except in planned districts, and except inside the coastal overlay zone. Category B covers all CO zones and all IP zones. Category C covers all CN zones and any commercial or industrial zone inside the coastal overlay zone — the coastal overlay moves a Category A or B site into C. Inside your category, the permitted area for a ground, roof, or projecting sign is read off a grid: adjacent public right-of-way width (60 feet or less / more than 60 feet) against street speed limit (15-20, 25-30, 35-45, 50+ mph). The four tables above print that grid. Two things catch people out — roof signs do not exist outside Category A, and the 100-foot frontage minimum for ground signs is Category B only.

3. Check whether you file a Building Permit instead

This is the step that sends applications back. DSD lists four conditions where the sign permit is the wrong application and you submit a Building Permit instead: the sign needs structural alterations to an existing building; California Building Code Chapter 17 requires special inspections for the installation (Technical Bulletin BLDG 17-4); the sign is a ground or monument sign taller than 7 feet; or a structural reviewer decides one is needed after reading your scope and calculations. Note the third one — a tall monument sign is not a sign permit with extra review, it is a different permit.

4. Check your overlays

Coastal Program zones, planned districts such as the Mid-City Communities and the beach-area planned districts, and historic districts each carry standards that can override the base §142 rules.

5. Assemble the plan set before you apply

IB 111 lists what a sign permit application carries: the Project Contacts Information form (DS-345), an Owner-Builder Verification (DS-3042) where it applies, and sign plans with project information, a site plan, a sign schedule and elevation drawings showing sign dimensions, copy, tenant frontage and attachment details. Structural calculations by a California registered architect or engineer are required for, among others, monument signs over six feet, wall signs over 70 sq ft or 600 lbs per sign box or channel letter, and roof signs. An incomplete submission may be rejected.

6. File online

Sign permit applications must be submitted through your online permitting account with the Development Services Department (DSD), and the electronic application must be complete for staff to do a full plan check. Uploaded PDFs must meet DSD’s upload requirements, and not following them delays review and approval; check the plan sheet numbers before uploading.

7. Know whether your sign gets inspected

Only some types are. DSD’s sign permit page says inspections are required for signs with electrical components, high-rise wall signs and freeway signs, and that all other types of signs do not require inspection. Where inspections apply, the fees are invoiced at permit issuance (IB 111).

8. Expect the fee in stages, not one payment

Plan check fees are paid before review, and inspection fees are invoiced at permit issuance. Every sign permit application also pays a General Plan Maintenance fee and a mapping fee, and each side of a multi-sided sign is charged as a separate sign. Plan check fees and some administrative fees are non-refundable (Refund Application Form DS-721).

9. Diary the exit condition

On-premise sign copy must be removed within 30 days after the business vacates — the obligation outlives the permit.

Steps assembled from City of San Diego Development Services official sign permit guidance (Sign Permit page; Information Bulletins 111, 501 and 581; Technical Bulletin BLDG 17-4) and from the confirmed items on this page. Fees and timing are handled in their own sections below — not repeated here.

How much does a San Diego sign permit cost?

San Diego charges a flat plan check fee by sign type, and adds an inspection fee only when the sign is electric. Quantity matters: the first sign costs the most and each extra one on the same application is cheaper.

Two fees land on every application regardless of sign type, and they are easy to miss.

Sign type	Quantity	Plan check	Inspection
Awning or wall sign, non-electric	1	$793.95	n/a
Awning or wall sign, non-electric	2 to 5 each	$793.95 + $88.89 each	n/a
Awning or wall sign, non-electric	each additional, 6 or more	$793.95 + $353.13 each	n/a
Wall sign, electric	1	$793.95	$353.13
Wall sign, electric	2 to 5 each	$793.95 + $88.89 each	$353.13 + $176.57 each
Wall sign, electric	each additional, 6 or more	$793.95 + $353.13 each	$353.13 + $176.57 each
Roof or projecting sign, non-electrical	1	$793.95	n/a
Roof or projecting sign, non-electrical	each additional, 2 or more	$793.95 + $353.13 each	n/a
Roof or projecting sign, electrical	1	$793.95	$353.13
Roof or projecting sign, electrical	each additional, 2 or more	$693.95 + $353.13 each	$353.13 + $176.57 each
Ground sign, non-electrical	1	$971.73	n/a
Ground sign, non-electrical	each additional, 2 or more	$971.73 + $440.82 each	n/a
Ground sign, electrical	1	$971.73	$353.13
Ground sign, electrical	each additional, 2 or more	$971.73 + $440.82 each	$353.13 + $176.57 each
Wall sign, high rise	each	$971.73	$176.57
Banner signs, each per banner district	1	$617.38	n/a
Freeway signs	each	$662.43	$353.13

One row reads $693.95 where every comparable row reads $793.95. That is how the city's bulletin prints it, so we print it the same way — ask Development Services which figure applies.

On every application	Amount
General plan maintenance fee	$737.00
Mapping fee	$12.16

Work the bulletin does not price is billed at the department's hourly rate, $176.84 an hour for plan review or inspection and $264.87 an hour outside normal hours.

How long it takes

San Diego publishes no guaranteed turnaround for a sign permit. What the City does publish is a live processing page and two plain warnings about what adds time — so the honest answer is a range you check rather than a number we print:

Why we quote no week count

This panel used to carry a week bracket taken from sign-industry guides. It was not a City figure, so it is gone — the DSD timeline page above is the only number to read, and it moves weekly.

The weekly processing-timeline page and the two delay warnings are City-published.

San Diego sign checklist — 6 items

Before you design or order anything, confirm:

What's the right-of-way width and speed limit on the street I face, and how long is my street wall? (Width and wall length set the wall sign; width and speed set the other sign types.)
Do I know my sign category — A, B, or C — and did I read my cap off that column (Table 142-12C)?
If I want a ground sign and I am in a CO or IP zone (Category B), do I have at least 100 feet of street frontage?
Am I adding a projecting sign next to a ground or roof sign? → a projecting sign is allowed only in lieu of them. Where two ground signs are allowed, a projecting sign may replace one, and both signs are then cut to half the table area (§142.1230(d)(3)).
Is the sign flashing or animated? → prohibited (beyond the limited 10 sq ft exception, §142.1210(a)(7)).
Am I in a Coastal, planned, or historic district? → expect extra review.

Official San Diego resources

Go straight to the city for permits and the binding code:

San Diego Sign Permit (Development Services) — application steps, exemptions and inspections, and Municipal Code §142. This page is the city's permit-application guidance, not the binding text.

The numeric limits on this page come from the binding ordinance text: San Diego Municipal Code, Chapter 14 Article 2 Division 12 — Sign Regulations (PDF). Re-read on 10 October 2026 (9-2026 edition): the PDF extracts as text and carries every wall-sign, ground-sign and animated-sign figure quoted here. It replaces the Development Services permit page as the source of record — that page is application guidance, not binding text. The American Legal code library still blocks automated access, so the city PDF is the only machine-readable copy.

I'm a new business owner and English isn't my first language — where do I start?

Start by measuring your street wall and finding the right-of-way width and speed limit on the street your sign will face — the calculator on this page turns those into allowances. Because the table is technical and coastal/planned-district overlays are common, a licensed sign company can confirm the allowance and pull the permit as part of the job.

Can this page tell me my exact square footage?

For the citywide rules, yes: the calculator applies Tables 142-12C, 142-12D, 142-12F and 142-12H to your category, street and wall. What it cannot see is a planned district, La Jolla or Ocean Beach rule, a historic review, or whether your street is designated a major street or primary arterial in the land use plan. Those need confirmation from Development Services.

This is an informational guide based on the public San Diego Municipal Code (§142.1210–142.1240), not a permit, legal advice, or a guarantee of compliance. Sign allowances in San Diego depend on street wall length, right-of-way width, street speed limit, sign type, and district overlays that require professional confirmation. Always verify with the City of San Diego Development Services and a licensed San Diego sign contractor before designing, ordering, or installing a sign.
