The permitting process is straightforward when you know what is required, but it trips up building owners and contractors who are unfamiliar with San Diego’s specific submittal requirements, fee structure, and review process. Understanding the system before you start your project prevents the delays that catch most first-timers off guard.
Types of Fire Permits in San Diego
The City of San Diego Development Services Department issues several types of fire permits depending on the scope of work.
Fire alarm permits are required for any new fire alarm system installation, any alteration to an existing system (adding, relocating, or replacing devices), fire alarm panel replacements, and sprinkler monitoring connections. A fire alarm final inspection is required for every project regardless of the number of devices involved.
Fire sprinkler permits are required for new sprinkler system installations, alterations to existing systems (adding or relocating heads), tenant improvement modifications, new backflow preventer installations, and sprinkler head replacements beyond simple maintenance.
Fire suppression permits cover specialty suppression systems including clean agent systems, kitchen hood suppression, dry chemical systems, and foam systems.
Fire underground permits are required for fire service underground piping from the water main to the building’s fire protection system connection.
A maintenance permit is not required for routine maintenance of fire suppression and fire alarm systems under Chapter 9 of the California Fire Code. Your annual inspection and testing program does not require a permit. But any work that adds, relocates, or replaces system components beyond basic maintenance does.
No-Plan Permits (Affidavits)
For smaller-scope projects, San Diego offers a streamlined “no-plan permit” process using affidavit forms. This is faster and less expensive than submitting full design drawings.
The Fire Alarm Affidavit (Form DS-163) can be used when the project involves the addition or alteration of 14 or fewer fire alarm devices in a building with an existing fire alarm system. The affidavit must be completed by a licensed architect, electrical or fire protection engineer, Class B general contractor, or C-10 fire alarm contractor certifying that the work complies with NFPA 72.
The Fire Sprinkler Affidavit (Form DS-161) can be used when the project involves the addition or alteration of 20 or fewer sprinkler heads in a building with an existing NFPA 13 or 13R system. The affidavit must be completed by a mechanical or fire protection engineer, Class B general contractor, or C-16 sprinkler contractor certifying that the work complies with NFPA 13 or 13R.
The affidavit process can often be handled over the counter (OTC) at Development Services, which means faster turnaround than the plan review process. Your fire protection contractor should be familiar with these forms and can determine whether your project qualifies.
Full Plan Submittals
Projects that exceed the affidavit thresholds, involve new systems, or include complex system types (pre-action, deluge, voice evacuation, smoke control) require full design drawings submitted for fire department plan review.
The submittal requirements for fire alarm plans include a completed Fire Permit Fee Worksheet (Form DS-506), fire alarm system design drawings showing all device locations and wiring, a sequence of operations describing how the system responds to every alarm, supervisory, and trouble condition, battery calculations demonstrating adequate backup power per NFPA 72, voltage drop calculations for notification appliance circuits, equipment specifications and cut sheets, and compatibility documentation for all devices with the fire alarm control panel.
The submittal requirements for fire sprinkler plans include design drawings showing pipe routing, head locations, and hanger details, hydraulic calculations demonstrating adequate water supply, a completed Hydrant Flow Request Form (DS-160) with flow data less than six months old, sway brace calculations per NFPA 13 seismic requirements, and equipment specifications.
Incomplete submittals are the most common cause of plan review delays. A design-build fire protection contractor who regularly submits in San Diego knows exactly what the reviewers expect and can prepare a complete package that moves through review without unnecessary back-and-forth.
Permit Fees
Fire permit fees in San Diego are calculated using the Fire Permit Fee Worksheet (Form DS-506). Fees are based on the type of system (fire alarm, sprinkler, suppression) and the scope of work (number of devices, number of floors, type of occupancy).
Fire alarm fees vary based on whether the project is a new installation, an alteration to an existing system, a panel replacement, or sprinkler monitoring. The fee increases with the number of devices and floors involved.
Fire sprinkler fees are calculated based on the project type (new installation, tenant improvement, head replacement, backflow, underground) and the scope of the system.
Your fire protection contractor should include the permit fee estimate in their project proposal so there are no surprises. The fees are paid at the time of permit application.
Inspections During and After Installation
After the permit is issued and work begins, the Development Services Department conducts inspections at specific milestones to verify the installation matches the approved plans. For fire alarm systems, inspections typically occur at the rough-in stage (wiring before walls are closed) and at final completion. For sprinkler systems, inspections occur at the underground stage, the rough-in stage, and at final.
A fire alarm final and a fire sprinkler final are required for every permitted project before the building can receive its certificate of occupancy. The final inspection verifies that the installed system matches the approved design, that all devices function correctly, and that the system passes acceptance testing.
Test results from the acceptance test must be submitted through The Compliance Engine as the first entry in the building’s ongoing fire protection compliance documentation.
Common Permitting Mistakes
The most frequent permitting mistakes on San Diego fire protection projects include performing work without a permit (discovered during fire department inspections, resulting in stop-work orders and potential removal of non-permitted work), submitting incomplete plans that get returned before review even begins, not including fire protection submittals with the tenant improvement building permit application, using a contractor who is not familiar with San Diego’s specific requirements and forms, and not scheduling required inspections at the correct milestones, resulting in work that must be uncovered for inspection.
Each of these mistakes costs time, money, and schedule. The simplest way to avoid them is to work with a fire protection contractor who handles San Diego permitting regularly and knows the process inside and out.
