Sign permit assistance means getting your sign approved before it is built, so it does not sit in storage waiting for the City. In the City of San Diego, most new or altered signs need a separate sign permit, and each sign on a property needs its own. Signs on San Diego helps business owners understand what applies to their sign and prepare what the City expects to see.
Does your sign need a permit?
According to the City of San Diego’s Information Bulletin 111, “How to Obtain a Permit for Signs,” a sign permit is required to install or alter a sign unless it falls under a listed exemption. Common exemptions include:
- Changing the copy on an existing sign, or maintaining it, without structural or electrical changes
- Interior signs, except theater lobby signs
- Window signs
- Temporary onsite banners, streamers and pennants
- Small nameplate or address signs within the size limits in the bulletin
Being exempt from a permit is not the same as being exempt from the rules. Exempt signs still have to follow the City’s sign regulations, and interior room, restroom and exit signs still have to meet accessibility requirements.
Which approvals might a sign project need?
| Approval | When it usually applies | Who reviews it |
|---|---|---|
| Sign permit | New or altered signs that are not exempt | City of San Diego Development Services |
| Building permit | Structural alterations to the building, special inspections, or ground and monument signs over seven feet tall | City of San Diego Development Services |
| Structural calculations | Larger or heavier signs, such as taller monument and pole signs, as listed in IB-111 | Prepared by a California-registered architect or engineer, reviewed by the City |
| Historic review | Designated historic resources and historic districts | City historic preservation staff |
| Landlord or HOA approval | Most leased and shopping center spaces | Property owner or association, under its own sign criteria |
If your business is outside City of San Diego limits, such as in Chula Vista, Escondido, Carlsbad or an unincorporated area, a different city or the County sets the rules and process.
What goes into a sign permit application?
IB-111 lists the core items the City expects, and incomplete submissions may be rejected until everything is provided. A typical package includes:
- The Project Contacts Information form (DS-345), plus an Owner-Builder Verification form (DS-3042) in some cases
- A site plan showing property lines, structures, existing and proposed signs, the street right-of-way and a north arrow
- A sign schedule listing each sign, its type, copy area and whether it is illuminated
- Elevation drawings with sign dimensions, copy and, for wall signs, the tenant frontage
- Attachment and footing details where they apply
Our full San Diego sign permit guide explains each item, the rules that shape sign size and placement, and how to apply.
What slows sign permits down?
- Missing frontage measurements: wall sign size is tied to tenant frontage, so plan check needs that dimension.
- Designing before checking the rules: a design that exceeds the allowed area or height has to be revised.
- Ignoring prior permits: properties with earlier discretionary permits may have their own sign conditions.
- Forgetting the coastal zone: roof signs, for example, are not permitted in the City’s coastal zones.
- Incomplete drawings: unclear attachment details or a missing sign schedule lead to corrections.
How do we help with sign permits?
- Confirm the jurisdiction: we check whether your address is in the City of San Diego or another city.
- Identify what applies: we review which of your signs need permits, which are exempt, and whether structural or historic review is likely.
- Plan within the limits: we help size and place signs within the allowed area and any landlord criteria.
- Organize the package: we help you assemble the drawings, schedule and forms the City asks for.
Permits are only part of the picture. Accessible signs follow their own rules, covered in our guide to ADA sign requirements, and materials affect how long an approved sign will last, as explained in our guide to sign materials for San Diego’s climate. If you are planning a new exterior sign, see our storefront and channel letter signs service.

Frequently asked questions
Do I need a permit to change the face of my existing sign?
Under IB-111, changing the copy on an existing sign does not need a sign permit when there are no structural or electrical changes. Replacing the cabinet or adding lighting is an alteration and likely needs a permit.
Does each sign need its own permit?
Yes. The San Diego Municipal Code requires a separate permit for each sign on a premises, so a wall sign and a monument sign are two permits.
Can a sign company apply for the permit on my behalf?
Often, yes, with the owner’s or tenant’s authorization. The City’s forms identify who is responsible for the project.
How much does a sign permit cost?
Fees are set by the City and change over time. Check the City’s current fee information for your project type.
