Do I need a remodel permit in San Diego? The $1,000 rule, no-plan kitchens and baths, and the 45-year historic check

The San Diego rule

The City's When is a Permit Required? sheet says owners of single-family homes, townhomes and duplexes "must obtain a permit before constructing, expanding, altering, renovating, relocating, demolishing or changing the use" of a building. Information Bulletin 203 (July 2024, read 23 October 2026) sorts remodel work into three groups:

The exemptions do not apply to a designated historical resource or a house in a historic district. IB 203 also says no-plan permits are only for buildings that were "legally permitted, constructed and passed final inspections", and if the inspector finds the work "too extensive", plans will be required and a new permit issued.

The 45-year check

This is the San Diego rule that surprises owners of older houses. IB 203: "If the site contains buildings or structures 45 years old or older, plans must be submitted through the Development Services Department for historic review, unless the project scope is exempted per San Diego Municipal Code §143.0212." The City says that review "will typically be ten business days" (see Information Bulletin 580). A house built before about 1981 should plan for it.

Two more triggers: once any permit is issued for repairs or replacements, smoke and carbon monoxide alarms must be brought to current code, and work that blocks or affects fire sprinklers needs its own permit.

Who can pull it

A licensed contractor. A remodel across trades is CSLB class B General Building or B-2 Residential Remodeling (CSLB). Unlicensed help is limited to jobs under $1,000 with no permit and no hired workers (CSLB, AB 2622). 63.1% of remodel firms in our file matched an active CSLB license and 14 matched one that was not.

You, as owner-builder. Sign the Owner-Builder Verification Form DS-3042. IB 203: "Tenants/Lessees may not sign this form," and it must be notarized if the owner is not present to prove identity.

How to apply and what it costs

Submit a no-plan building permit online through the City's portal, choosing the Building Construction application, with the Project Contacts form (DS-345) and the No-Plan Building Permit Supplemental Application (DS-6005). IB 203 says a virtual appointment can be booked after submittal for help. Building permit fees are in Information Bulletin 501, which we did not verify, so we give no building fee here.

The trade side has a published figure. IB 103, Table 3A, prices a residential "existing Kitchen/Bathroom Remodel with no changes to structural elements, wall framing or exterior walls and no added plumbing fixtures/gas appliances" at $440.82 per dwelling unit, a fee that "includes the cost of a no-plan combination permit for all plumbing, mechanical, and electrical work". Against the usual $18,998 filed value, that is about 2% of the job. For local prices, see San Diego remodel cost; national ones are in home remodel cost.

What 1,681 San Diego remodel permits show

Remodel permits finish more often than San Diego's trade permits (79.1%, against 61.4% for HVAC), but take far longer: 162 days is the life of the job, not the paperwork. Most remodelers are small: 71.3% of firms filed one permit in three years, so the compare list is more useful for the firms with a record than for ranking them all. Filing peaks in July and is lowest in December.

What this does not tell you

This is the City of San Diego only. Our remodel count holds building permits for alterations to existing homes; additions and ADUs are counted separately. A filed value is the applicant's estimate, not the contract price. We could not verify IB 501's building permit fees, so ask Development Services (619-446-5000) or read the invoice.
