Before replacing or installing a new water heater in San Francisco, a permit is required from the Department of Building Inspection (DBI).

Keeping up with these rules can be a difficult undertaking for homeowners. Fortunately, Advance Plumbing takes care of all the details for you, ensuring your new water heater installation is compliant, efficient, and hassle-free.


Understanding San Francisco Water Heater Requirements

San Francisco has stringent building codes designed to ensure safety, energy efficiency, and environmental responsibility. Here’s a detailed overview of what you need to know about San Francisco Water Heaters local building codes and safety standards:

Water Heater Local Codes and Safety Standards


1. Locations for Water Heaters

  • Approved Locations: Water heaters in San Francisco can be installed in utility rooms and garages, where they are well-ventilated and isolated from living areas
  • Location Restrictions: Water heaters should not be installed in bedrooms, bathrooms, or closets used for other purposes. These areas are deemed high-risk due to the potential for gas leaks and carbon monoxide (CO) emissions, which could pose serious health risks if the water heater malfunctions​ 

2. Seismic Requirements

  • Earthquake Safety with Straps –In earthquake-prone areas such as San Francisco, California law requires water heaters to be secured with approved straps around the top and bottom thirds to prevent tipping during seismic activity.
  • Positioning: Properly securing the water heater helps prevent gas leaks, water damage, and potential fires that could occur if the unit were to fall or shift during an earthquake​ 

3. Combustion Safety

  • Venting Requirements: Gas water heaters must be vented outdoors to prevent carbon monoxide accumulation indoors, using materials like stainless steel. The California Plumbing Code mandates non-corrosive, correctly sized vent pipes to safely handle exhaust gases and maintain clearances to prevent fires and ensure efficient venting.

4. Pans and Drains to Prevent Water Damage

  • Drain Pan Requirement: If there is a risk of water leaks from the heater, a drain pan with an external drain line is mandatory. This helps capture and redirect leaking water to a safe discharge location, reducing the risk of water damage to surrounding areas​ 

5. Pressure and Temperature Relief Drain (P&T Drain)

  • Scald Prevention: P&T relief valves on water heaters must discharge hot water safely outside or to a secure area to prevent scalding due to excessive pressure or temperature. In some cases, a Watts 210 valve can be used as an alternative to shut off the gas supply if the water temperature becomes unsafe, adding an extra safety measure.

6. Dedicated Water Shutoff Valve

  • Shutoff Requirement: A dedicated shutoff valve for the water heater allows maintenance or repair work to be done without interrupting the water supply to the rest of the house. This ensures minimal disruption during servicing and enhances safety by isolating the heater from the water supply​

7. Pipe Insulation in Unconditioned Spaces

  • Insulation Requirement: Pipes in unconditioned spaces, like attics or basements, must be insulated to prevent heat loss and to protect them from freezing. Insulation helps maintain water temperature, reduce energy consumption, and safeguard against potential damage due to temperature fluctuations​ 

8. Safety Bonding for Pipes

  • Grounding Requirement: Gas and water pipes must be grounded to prevent electrical hazards, particularly in areas near electrical wiring. Proper grounding helps protect against electrical shocks and ensures compliance with local safety regulations​. This requirement ensures that all plumbing systems are safely integrated with the home’s electrical system, reducing the risk of electrical accidents​ 


Energy Efficiency Standards

California has some of the most stringent energy efficiency standards in the country. When installing a new water heater in San Francisco, you must ensure it meets the latest energy efficiency criteria, which are designed to reduce energy consumption and minimize environmental impact. It includes considering factors like the Energy Factor (EF) rating of the unit and potential rebates for high-efficiency models.


Permit Requirements

Installing or replacing a water heater in San Francisco requires obtaining the appropriate permits. These licenses guarantee the installation complies with all safety regulations and building code requirements. The types of permits typically needed include:

  • Plumbing PermitIt covers the installation of the water heater and any modifications to the plumbing system.
  • Electrical PermitIf the installation involves any electrical work, such as connecting an electric water heater or updating wiring, an electrical permit is required.
  • Mechanical Permit – It may be necessary for gas water heaters to cover aspects like venting and gas line connections.
