Do You Need a Permit to Remodel a Bathroom in San Diego?

Only when the work goes past the fixtures. San Diego Municipal Code section 129.0403(a)(3) exempts replacement in kind of plumbing fixtures unless the installation requires altering or replacing drainage, waste, vent or water supply piping, and Information Bulletin 203 adds tub-to-tub and shower-to-shower replacements that do not change size or location, plus drywall replacement up to 100 square feet when repairing wiring or plumbing. The Development Services Department (DSD) handout lists showerheads, plumbing fixtures, switches, light fixtures and receptacles among the things you may replace without a permit. Tile, paint and flooring are exempt finish work. What needs a permit: any altered or added piping (section 129.0402), any new or altered wiring (section 129.0302), a new exhaust fan, a water heater, and anything structural. Turning a half bath into a full bath, or moving the toilet, is a plumbing job at minimum and a plan-checked building permit if walls move.

How Much Does a Bathroom Remodel Permit Cost in San Diego?

A bathroom remodel that leaves the structure, wall framing and exterior walls alone and adds no plumbing fixtures or gas appliances takes a No-Plan Building Permit priced by Information Bulletin 103, Table 3A, at $440.82 per dwelling unit, including the no-plan combination permit for all plumbing, mechanical and electrical work. No plans are reviewed, so the General Plan Maintenance Fee does not apply. A remodel that needs plans is billed on IB 501, Table 501A, as a Residential Single Dwelling Unit or Duplex Addition/Remodel: $3,512.92 plan check and $2,228.29 inspection for the first 500 square feet, plus the $737.00 General Plan Maintenance Fee and a $12.16 mapping fee, about $6,490.37 before state fees, a $17.11 collection charge and the $58.00 lead hazard fee on pre-1978 homes. Single-item trade permits are cheaper: an exhaust fan is $105.98, a water heater $122.97, residential water or waste pipe replacement $264.25 per dwelling unit, and up to five new circuits $176.57.

Who Pulls the Permit and What Comes With It

All permits are filed online. Simple Permits go to licensed contractors as soon as the invoice is paid and to homeowners within about two business days of uploading the signed Owner-Builder Verification Form DS-3042; tenants cannot sign it. Plumbing and electrical permits may be issued only to state-licensed contractors or the property owner or lessee. Any permit in an existing home requires smoke and carbon monoxide alarms to be brought to code, and the Electrical Circuit Card DS-1779 is checked at inspection. If the inspector decides a no-plan job is too extensive, plans are required and a new permit issued. Interior-only work on a 45-year-old house is exempt from Potential Historical Resource Review; a designated historical resource needs plans and review for any scope and cannot use Simple Permits. Plan-reviewed remodels are Short projects with an estimated 8 business days for the first review; stand-alone trade permits expire if no inspection is passed within 180 days and cannot run past two years.
