The California Title 24 Mandate

Standard Gas Water Heaters Are Being Phased Out

Starting soon, non-compliant standard gas water heaters will be phased out of California. When your old tank fails, you will likely be forced to upgrade to a high-efficiency condensing unit or a heat pump. Upgrading isn’t as simple as swapping a tank — high-efficiency units require entirely new infrastructure: dedicated 110v or 220v electrical circuits, condensate drain lines with acid neutralizers, and sealed PVC venting routed to the exterior. Our Advice: If you are planning a remodel right now, run the utilities early. Even if you aren’t replacing the heater yet, getting the drain, vent route, and electrical in place will save you thousands of dollars down the road.

Your Richmond District Home Advantage

Ground-Floor Garages Make Title 24 Upgrades Smooth

Upgrading a water heater to meet new high-efficiency standards can be difficult in older San Francisco Victorians, but homes in The Richmond typically have layouts that make the transition much smoother and significantly less expensive. Ground-floor garages with nearby utilities and accessible exterior walls mean we can complete most upgrades without touching your finished living spaces. The Richmond is one of the most straightforward neighborhoods in SF for high-efficiency upgrades — and one of the few where a heat pump water heater is actually a viable option.

Common Questions — The Richmond

Can I install a heat pump water heater in my Richmond home?

If you have a standard garage, very likely yes. Heat pump water heaters need approximately 900 sq ft of airflow clearance — which most Richmond garages provide. This is a genuine advantage Richmond homes have over denser inner-city flats like Hayes Valley where heat pumps simply don’t fit. That said, we always assess the specific space and recommend the correct unit size, since undersizing a heat pump is one of the most common mistakes we see.

Has my water pressure changed after recent street work?

Probably, and you likely weren’t notified. SF infrastructure work can double your water pressure without any resident notification. We check pressure on every service call — most plumbers don’t. Safe pressure is 65 PSI; we regularly see 130+ PSI in homes near recent dig sites. A pressure reducing valve protects your fixtures and extends the lifespan of your entire system.

Do I need a State Farm leak detection device?

If you’re insured with State Farm, yes — they now require a whole-home leak detection device ($1,500–$2,000 installed) as a policy condition. Without it, you risk losing coverage. The device monitors flow and pressure 24/7 and automatically shuts your water off if it detects an abnormal leak pattern. We supply, install, and commission these units.

What permits does SF require for plumbing work?

Any plumbing work over $500 must be permitted in San Francisco. Water heater replacements require permits and seismic strapping. Earthquake gas shutoff valves are required when selling or completing major remodels. We handle the entire SFDBI permitting process for you.
