Custom Homes, Remodels & Additions in Marin County
Full-service residential construction for Marin County — whole-home remodels, custom homes, ADUs, and additions — from Mill Valley and Sausalito to Tiburon and Belvedere, by a builder headquartered in Napa with thirty years of work in San Francisco.
The Marin Context
Between our two home bases — and on our route every week.
Marin sits squarely between Napa, where Mavericks Builders is headquartered, and San Francisco, where most of our work is. The Mill Valley, Sausalito, Tiburon, and Belvedere corridor is on our route every week. We bring the full scope of high-end residential work — whole-home remodels, ground-up custom homes, ADUs, and additions — with the craft, code fluency, and project control of a thirty-year builder. Every project is managed end to end, from siting and permits to final finish.
What sets the work apart is the terrain. Marin's hillside lots, tight access, and view-driven designs call for engineered foundations, careful retaining and drainage, and a builder who has put houses on steep sites before. Robin pairs that with green building — she is a USGBC LEED for Homes pioneer, and her San Francisco project served as the national demonstration home for the program — the kind of high-performance, low-energy construction Marin owners ask for.
Communities Across Marin
Communities we serve in Marin County.
From the canyons of Mill Valley to the shoreline of Sausalito — and every hillside in between.
Mill Valley
Wooded canyon and ridge homes where hillside foundations, drainage, and access do the heavy lifting.
Tiburon
Steep peninsula sites with commanding bay views — where Mavericks has completed projects.
Belvedere
Waterfront and hillside estates where precision detailing and material quality define the work.
Ross
Established estate properties under tree canopy, where remodels must respect the home's character.
Kentfield
Wooded valley-floor and slope homes that call for careful siting and high-performance building envelopes.
Sausalito
Tightly built hillside lots with challenging access — the kind of constrained site we've built on in San Francisco and Woodside.
Plus all of Marin — San Anselmo, Larkspur, Corte Madera, Fairfax, San Rafael, and the unincorporated hillside communities. If it's in Marin County, we'll come walk it with you.
Section 01 — Marin Expertise
What it takes to build well in Marin County.
Hillside & Sloped-Site Construction
Engineered foundations, retaining systems, and access strategies for the steep, sensitive lots that define Marin. Building uphill is its own discipline, and it's one Robin has practiced for thirty years in San Francisco and on the Peninsula.
Custom Remodels & Whole-Home Renovations
From a measured kitchen reconfiguration to a full whole-home remodel, Robin renovates established Marin homes with the craft, code fluency, and project control of a thirty-year general contractor.
Green Building & LEED
High-performance, low-impact assemblies from a USGBC LEED for Homes pioneer who delivered the national demonstration home for the program — sustainability engineered into the house, not bolted on.
ADUs & Additions on Tight Lots
Accessory dwelling units, second stories, and additions that add space and value on Marin's constrained parcels — including a second-story addition on a new foundation in San Francisco.
Fire-Resistant Construction When Your Site Calls for It
Class A roof assemblies, ignition-resistant siding, ember-resistant vents, and non-combustible decks to CBC Chapter 7A and Title 24, Part 7 — detailing we build every day in Napa and Sonoma, available for Marin's designated hazard zones.

Whether you need a general contractor for a ground-up build or a partner for a sensitive hillside remodel, every Marin project carries the same standard of craft and attention.
Section 03 — The Standard
A hillside home is only as good as the builder who put it there. Robin builds to that standard.
Building on Marin's slopes means treating the site as a design constraint, not an afterthought — foundation, drainage, envelope, and decks resolved as one system, on terrain that rewards a builder who has done it before.
