Do I need a permit to install a tankless water heater in Los Angeles
Yes, you need a permit to install a tankless water heater in Los Angeles. The installation must comply with local plumbing and energy codes, including proper venting, gas line sizing, and expansion tank requirements. GR Plumbing handles permitting, code compliance, and inspections as part of your installation.
To better understand what’s required, refer to the Oakland CA Planning & Building: Tankless Water Heater Requirements, which outlines essential state-aligned installation regulations, including venting and gas piping standards.
Why Choose a Tankless Water Heater?
Tankless water heaters, also known as on-demand water heaters, only heat water when it is needed. This means:
- Endless Hot Water: Never run out, even during back-to-back showers.
- Energy Efficiency: Save on energy bills with no standby heat loss.
- Compact Design: Mounts on walls, saving valuable floor space.
- Longer Lifespan: Typically lasts 20+ years with proper maintenance.
Whether you're upgrading or building new, GR Plumbing will help you select and install the right unit for your needs.
Do You Need a Permit to Install a Tankless Water Heater in Los Angeles?
Absolutely. A permit is required for tankless water heater installation in Los Angeles to ensure the work meets California Plumbing Code and safety regulations. This includes:
- Gas line sizing and upgrades
- Ventilation and air intake installation
- Earthquake safety strapping
- Electrical and water connections
- Inspection scheduling
GR Plumbing will file for the necessary permit and coordinate with the city inspector, so you don’t have to worry about red tape.
Are Tankless Water Heaters Allowed in California?
Yes. California encourages the use of tankless water heaters due to their energy efficiency and compliance with environmental standards. The state even offers rebates through local utilities for energy-efficient models. However, installations must comply with:
- Title 24 energy standards
- Low-NOx emission rules
- Seismic safety regulations
GR Plumbing stays updated on these standards to ensure every installation meets or exceeds state mandates. You can also reference InterNACHI Standards: Tankless Water Heater Inspection & Bonding to learn about safe installation and inspection guidelines followed by certified professionals.
Does a Tankless Water Heater Need an Expansion Tank in California?
In many cases, yes. California plumbing codes require expansion tanks for closed-loop systems to manage thermal expansion and prevent pressure buildup, especially when check valves or pressure regulators are installed. GR Plumbing will evaluate your plumbing setup and install an expansion tank if necessary.

"Would definitely recommend these guys for plumbing jobs."
He sent out his technician to do the job for me. He removed the nut and the old cartridge, installed the new cartridge and saw that is was leaking, He then spent about 10 minutes cleaning out the calcium deposits in the line so the new cartridge fits snug
