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 Outer Sunset Home Advantage

Coastal Location, Garage Access — and Salt-Air Ready Hardware

Homes in the Outer Sunset typically have garage or basement water heater locations that make Title 24 upgrades significantly easier than in denser inner-city neighborhoods. Being close to the ocean adds one extra consideration: salt air accelerates corrosion on standard outdoor units. We’re experienced with coastal installs — we know which equipment holds up and which doesn’t. Whether you’re installing indoors or exploring an exterior mount to free up garage space, we’ll guide you toward hardware that handles the Sunset’s marine environment.

Outer Sunset ADU Radiant Heating

The Outer Sunset’s Garage Layouts Are Radiant-Ready

The Outer Sunset is one of the strongest neighborhoods in SF for ADU radiant heating. Coastal proximity means the fog-driven chill is real — warm floors aren’t a luxury here, they’re practical comfort. And the neighborhood’s typical garage layouts provide exactly the conditions radiant heating thrives in: new concrete pours, open framing, and accessible ceiling cavities. When you’re converting a garage or pouring an ADU slab, that’s the window to embed radiant tubing. Once concrete sets or framing is drywalled, the cost multiplies significantly. A combi-boiler manages both heating and domestic hot water — and handles the salt-air environment when properly specified.

Common Questions — Outer Sunset

My garage is open to the elements on one side — can I still do radiant heating?

Yes. The boiler and mechanical components live indoors; only the radiant tubing runs through the slab or subfloor. For the boiler itself, we specify units rated for coastal environments and ensure any outdoor-mounted equipment is protected from direct salt-air exposure. The new construction radiant install is the same — coastal proximity just factors into hardware selection.

Has my water pressure changed after recent street work?

Probably, and you likely weren’t notified. SF infrastructure work can double your water pressure in a specific neighborhood 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.

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. The device monitors flow and pressure 24/7 and shuts your water off automatically if it detects an abnormal 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. We handle the entire SFDBI permitting process for you.
