What projects qualify for PermitLA express permits?
Simple work that does not need plan review, including many reroofs, water heater changeouts, and HVAC replacements on one- and two-family properties. Anything structural or that expands floor area goes through ePlanLA.
Does my Los Angeles home qualify for the soft-story retrofit program?
The mandatory program covers wood-frame buildings with four or more dwelling units and a soft, weak, or open-front first story, built under a permit before January 1, 1978. If your home is a single-family or duplex, it is not covered.

For most households in 2026, a heat pump water heater still offers the lowest operating cost (roughly $150–$300/yr cheaper than tank electric or gas). Tankless gas is best for large families wanting endless hot water. Tank gas is the budget choice. See our tankless vs tank comparison for the full 15-year math.
Permit requirements in Los Angeles follow California state building code plus local amendments. No, not for 2026 installs. The Section 25C Energy Efficient Home Improvement Credit (up to $2,000 for qualifying heat pump water heaters) expired December 31, 2025 under the One Big Beautiful Bill Act (P.L. 119-21). Units placed in service on or after January 1, 2026 receive no federal credit. If you installed a qualifying heat pump water heater in 2025 or earlier, you can still claim the credit on your 2025 return using IRS Form 5695. See our California permit guide for specifics.
Tank gas: 8-12 years. Tank electric: 10-15 years. Tankless: 20+ years. Heat pump: 13-15 years. Hard water reduces lifespan significantly — consider a water softener if your area has hard water.
Yes. Water heater replacement typically requires a plumbing permit. If switching from tank to tankless, you may also need a gas line permit and electrical modifications.
We do not recommend it. Water heater installation involves gas/electrical connections, venting, pressure relief valves, and code compliance. Improper installation can cause gas leaks, carbon monoxide poisoning, or flooding. Most jurisdictions require a licensed plumber.
