Codes & Inspections
Drywall Permits, Code & Inspections in San Diego
Most new drywall in San Diego is part of a bigger permitted project, like a room addition, an ADU, a garage conversion, or a commercial build-out. That work gets inspected before the walls are closed up.
Who handles your permit. San Diego County doesn't have one building department. If you live in the City of San Diego, your permit and inspections go through the City's Development Services Department. Cities like Chula Vista, Carlsbad, Oceanside, Escondido, and El Cajon each run their own. Unincorporated areas, such as Ramona, Alpine, Lakeside, Spring Valley, and Fallbrook, go through the County. Rules and inspection wait times can differ between them, so we check which one covers your address before we schedule anything.
Inspections before drywall goes up. Framing, electrical, plumbing, and insulation all need to pass inspection before we hang drywall. Once the board is up, that work is hidden. If drywall goes up too early, it may have to come back down, which is expensive. We set our start date around your inspection schedule so we're never the reason a project stalls.
The drywall inspection. When drywall is part of a fire-rated wall or a shear wall, the inspector checks it after it's hung but before any tape or mud goes on. They look at the type of board and how the screws are spaced. We hang every sheet to pass this check, and we don't start taping until it's signed off.
Fire-rated drywall. This comes up most often in San Diego garage conversions, ADUs, and homes with a room over the garage. California code requires at least 1/2" drywall on the garage side of the wall shared with the house. If there's a bedroom or other living space above the garage, the garage ceiling needs 5/8" Type X fire-rated drywall. Walls between an attached ADU and the main house, and walls between commercial tenants, usually need a fire-rated wall system too. Your approved plans will show exactly what's required.
Sound-rated walls. In apartments, condos, and other buildings with more than one unit, California code sets a minimum level of soundproofing for the walls and floors between units. Meeting it takes more than just the drywall. The insulation, the number of drywall layers, and how gaps are sealed all count.
Older homes and asbestos. Many San Diego homes were built before 1980, when some joint compound and popcorn ceilings contained asbestos. If your project means removing old drywall or ceilings in an older home, have the material tested before work starts. If asbestos is found, it has to be removed by a certified abatement company before we can begin.
Licensing. In California, drywall work over $1,000 in total labor and materials must be done by a licensed contractor. A license is also required for any job that needs a building permit, no matter the price. Look for a C-9 Drywall license, or a B General Building license that covers the work. You can check any contractor's license for free on the Contractors State License Board (CSLB) website before you hire. We're fully licensed and insured for every project on this page, and we're happy to share our license number and proof of insurance with your quote.
One thing to keep in mind: requirements depend on your project and where you live in the county. The final word always comes from your approved plans and your inspector. What we bring is over a decade of experience to build what they'll check for, and pass the first time.
