How I Helped Write the LEED for Homes Standard

How collaborating with the US Green Building Council to develop the LEED for Homes program shaped the way we build everything else.

Long before green building was a marketing line, it was an open question — and a few of us were trying to answer it. When the US Green Building Council set out to create a residential standard, they needed real homes to build it from: places where the ideas could be tested against framing, weather, trades, and budgets instead of theory. One of those places was a project of mine in San Francisco. It served as a national demonstration home — a working model from which the guidelines for the LEED for Homes program were established. I hold the USGBC documentation that records that collaboration, and I'm prouder of it than almost anything else with my name on it.

That program has since certified more than 200,000 homes across the country. I didn't just build green — I helped define what green building means. And while green building remains a genuine specialty of mine, it has never been the whole job. Mavericks Builders is a full-service bespoke general contractor: custom homes, gut remodels, ADUs, additions, commercial work, and winery estates. Helping write a national standard simply changed how I approach all of it. Here's what that work taught me.

1. The envelope is the whole game

Everyone wants to talk about the visible things — the kitchen, the finishes, the fixtures. But the part of a house that determines whether it's comfortable, quiet, durable, and cheap to run is the part you never see again once it's closed up: the envelope. Insulation, air sealing, window specification, the continuity of the whole assembly.

Helping develop the LEED for Homes criteria forced me to measure the envelope rather than assume it. Once you've watched a blower-door number drop because you took the time to seal a single rim joist properly, you stop guessing. Today we build every project — green-certified or not, a Pacific Heights remodel or a Napa estate — as if someone is going to test it.

2. Performance and protection are the same discipline

This is the lesson that turned out to matter most in Northern California. The same rigor that makes a home energy-efficient — a tight, well-detailed, intelligently specified envelope — is the rigor that makes a home resist fire. Ember-resistant venting, non-combustible assemblies, careful detailing at every transition: these aren't a separate "fire package." They're what happens when you already build the envelope with discipline.

Helping write a green standard taught me to sweat the details no one sees. Fire country taught me those same details save the house.

That's why I don't sell green building and fire-resistant construction as two unrelated services. They're one philosophy. A home built to perform is already most of the way to a home built to survive.

3. Durability is the most underrated form of sustainability

The greenest house is the one you never have to tear apart and rebuild. Defining what counted toward the standard pushed me to choose materials and assemblies for how they'd hold up in twenty years, not how they photographed on day one:

• Flashing details that actually shed water, year after year.
• Materials that age gracefully instead of failing early.
• Systems a homeowner can actually maintain and service.
• Assemblies detailed to be repaired, not just replaced.

Discerning clients sometimes expect the opposite — that the highest-end home is the most delicate one. The truth is the reverse. The finest homes we've built are the most robust. They're designed to be lived in hard and to still be standing, beautifully, decades later.

4. The standard doesn't move when the address changes

People assume a Napa winery estate, a downtown commercial build, and a San Francisco remodel require different levels of care. They don't. They require different knowledge — SF permits and codes versus Napa's agricultural overlays and fire requirements — but the standard of build is identical. Helping establish a national benchmark taught me to hold one bar and bring it everywhere. A client in Napa Valley gets the same envelope discipline as a client in San Francisco, whether the project is a custom home, an ADU, or an estate.

5. Being early is lonely — until it isn't

For years, building this way meant explaining myself constantly. Now California's codes have caught up: Title 24, Part 7 and CBC Chapter 7A require, by law, much of what we wrote into a voluntary standard a generation ago. The clients who built green and fire-hardened homes with me look prescient today. The lesson is simple — when something is clearly right, you don't wait for the regulation. You help write where the world is going, then you build to it.

That's still how I work. Whether it's a remodel in the city, a commercial project, or an estate in wine country, we build the home we'd want to own: efficient, durable, protected, and beautiful — in that order, because in this region, that order is what keeps a home standing. Green building is where I helped set the standard. Full-service bespoke construction, done to that standard, is what I do every day.
