Codes and local rules
The City of San Diego enforces the 2025 California Plumbing Code, part of the 2025 California Building Standards Code (Title 24), for projects submitted on or after January 1, 2026. The City’s permit guidance lists water heater replacement among the work that requires a permit; replacing a tank-type water heater, repairing water, sewer or gas piping and repairing drains generally qualify for a simple no-plan permit, except at historically designated properties.
The City is the water purveyor and runs a cross-connection control program. Where backflow protection is required, Information Bulletin 113 calls for a reduced pressure principle assembly immediately behind the meter on private property for domestic and irrigation services, and a reduced pressure principle detector assembly for fire services. Dedicated irrigation meters, regardless of size, need a backflow prevention assembly at each meter. All backflow devices must be tested every year.
Every food service establishment in the City needs a FEWD permit. The program regulates two kinds of grease control devices: hydromechanical grease interceptors, usually small units installed indoors, and gravity grease interceptors, larger underground units outside the building that must have a sample box. After a sewer spill, FEWD inspectors investigate nearby facilities, and continued noncompliance can lead to fees, permit revocation and termination of sewer service.
City water use restrictions require customers to repair leaks upon discovery or within 72 hours of notification by the City. Locations in Del Mar, Carlsbad and other cities in the county follow their own water and sewer agencies, so testing and grease rules are confirmed for each address.
Preventive maintenance schedule for commercial plumbing in San Diego
Plumbing work is mostly on demand, but scheduled drain, water heater and grease interceptor service keeps small problems from becoming closures. At San Diego restaurants and stores, planned work reduces backups during trading hours, extends equipment life and produces the backflow test and pump-out records the City’s programs look for.
| Task | Recommended frequency | Basis |
|---|---|---|
| Test backflow prevention assemblies by a City-approved tester | Annually | City of San Diego Public Utilities Department |
| Pump and clean grease interceptors | At the interval set for the site under its FEWD permit, and sooner once grease and solids reach 25 percent of the wetted depth | City of San Diego FEWD Program; 25 percent rule as an industry practice, from the City of Bloomington, Indiana, maintenance procedure |
| Drain a quart of water from storage water heater tanks to remove sediment | Every 3 months | U.S. Department of Energy, Energy Saver; manufacturer instructions |
| Check the water heater temperature and pressure relief valve | Every 6 months | U.S. Department of Energy, Energy Saver; manufacturer instructions |
| Jet or snake high-use kitchen and restroom drain lines | Quarterly to twice a year, based on backup history | Facility First program default, adjusted per site |
| Inspect restroom fixtures, flush valves, supply stops and visible piping for leaks | Quarterly | Facility First program default, adjusted per site |
| Exercise main and fixture shutoff valves | Annually | Facility First program default, adjusted per site |
The authority having jurisdiction, the manufacturer and the property’s insurer can require more frequent service, and each location’s schedule is set in its program and recorded on every visit.
Seasonal and local conditions
Water conservation is a permanent part of operating in San Diego. The City’s 72-hour leak rule means a running toilet or a leaking supply line is treated as a priority repair, and leak checks are part of every quarterly fixture inspection. Irrigation backflow assemblies at retail centers and office campuses are tested on the same annual cycle as domestic assemblies.
Storm drains and roof drains that run through ceilings above sales floors and dining rooms are checked before the rainy months, so a blocked line does not back up into the space. Seismic risk also makes it sensible to confirm that water heaters are properly strapped and gas connections are in good condition during service visits.
Where Facility First works in San Diego
Facility First manages plumbing for restaurants in the Gaslamp Quarter, shops and restaurants along Prospect Street and Girard Avenue in La Jolla, stores at Fashion Valley and University Town Center, and retail and office sites in Del Mar and Carlsbad. Restaurant kitchens drive most grease interceptor and drain work; retail and office sites drive restroom, fixture and water heater calls. Industries served include retail, restaurants, offices, banks, hotels and distribution sites. Restaurant work is scheduled around service, retail work before opening or after close, and office work under building access rules.
How plumbing requests are handled
- Request. Submitted through the platform or by phone, with photos where available.
- Triage. Facility First confirms scope, priority, warranty and whether a permit, backflow test report or FEWD record is involved.
- Dispatch. A vetted plumbing provider in San Diego holding a current CSLB C-36 license receives the work order.
- Photo close-out. The provider documents the repair, test result or pump-out manifest.
- Verification and invoice. The work is checked against the request and invoiced in one format.
Work within the client’s approval limits proceeds directly; anything above a limit, such as a water heater replacement or interceptor repair, is quoted first.
