Light-gauge steel and metal stud framing in Larkspur — interior partitions, tenant-improvement walls, soffits, and fire-rated assemblies.

Larkspur Framing From the Fairfield Shop
Ron Hogan Drywall has been family-owned since 1970. We are based in Fairfield — a Marin run, not a Magnolia Avenue storefront. Larkspur is an incorporated city in Marin County — not Corte Madera, not Mill Valley, and not San Rafael. It has its own Building Division at City Hall, 400 Magnolia Avenue, second floor. Street ZIP 94939 is Larkspur. 94977 is a Larkspur PO Box. 94904 is Greenbrae. 94925 is Corte Madera. This page is steel / metal stud framing at City of Larkspur addresses — Magnolia Avenue, Larkspur Landing Circle, Larkspur Plaza Drive, Doherty Drive, and Sir Francis Drake Boulevard when the lot is Larkspur. The street decides the bid.
Text “Larkspur” with the plans or a photo of the room. If the scope is interior metal studs — or frame-and-hang on the same trip — we schedule it.
Metal Stud Work We Do in Larkspur
Interior partition walls
Track, studs, and bracing for new rooms, office layouts, and non-load-bearing walls in Larkspur 94939 addresses. This is the skeleton the board hangs on.
Magnolia Avenue TIs
Shop, restaurant, office, and commercial build-outs on Magnolia Avenue — Larkspur’s downtown historic district — when the drawing says steel studs. If the plan names metal, that is the bid. Commercial framing →
Larkspur Landing and Plaza interiors
Office, retail, and ferry-adjacent partitions on Larkspur Landing Circle, Larkspur Plaza Drive, and East Sir Francis Drake Boulevard. Occupied buildings change the layout — not the stud spec.
Doherty, Bon Air, and city-limit interiors
Shop and office partitions on Doherty Drive, Bon Air Road, Madrone Avenue, and Locust Avenue. Parts of Greenbrae sit inside Larkspur city limits — the parcel still decides the permit office.
House remodel and ADU partitions
New interior steel walls inside an existing Larkspur house when the finish needs a straighter plane than bowed lumber. Wood structure stays wood unless the plan says otherwise. Metal vs wood →
Soffits, bulkheads, and chases
Dropped ceilings, kitchen hood wraps, and framed openings so boxes, ducts, and lights have a home before drywall.
Fire-rated and heavier-gauge walls
Listed assemblies, Type X board later, and heavier studs when the plan or the engineer calls for them. The rating is the whole wall — not the stud alone.
Frame and hang together
One crew frames the metal, hangs the board, and can finish it. Split bids leave missing backing and wavy walls. Services →
Which Stud Belongs on a Larkspur Job
| Stud | Use it when | Skip it when |
|---|---|---|
| Light-gauge metal (what we frame) | Magnolia Avenue TI, Larkspur Landing office walls, Plaza retail, rated partitions, or a finish that needs a flat plane for Level 4 / Level 5 | You need beams, columns, or hillside structure that hold the building up — that is a different contractor |
| 25-ga interior studs | Short, non-load-bearing partitions with a normal finish | Tall walls, high-abuse corridors, or a spec that names 20-ga or heavier |
| 20-ga / heavier track and studs | Taller commercial walls, Landing office TIs, or engineer notes | A simple closet that never needed the extra gauge |
| Wood studs | Most Larkspur house walls with no commercial spec | The plan already says steel, or the finish will show every bow |
| Furring / hat channel on masonry | Concrete, brick, or masonry walls that need a cavity for boxes before drywall | Glue-only board on a finished living space |

Larkspur Streets, ZIP, and Permits
Larkspur is an incorporated city in Marin County. This page uses street ZIP 94939. 94977 is a Larkspur PO Box. Area codes are 415 and 628. Nearby Greenbrae uses 94904. Corte Madera uses 94925. Kentfield uses 94904 / 94914. Mill Valley uses 94941. San Rafael uses 94901. Text the street so the bid matches City of Larkspur Building Division — not Town of Corte Madera Building at 300 Tamalpais Drive, not City of Mill Valley Building at 26 Corte Madera Avenue, not City of San Rafael Building at 1400 Fifth Avenue, and not Marin County Building at 3501 Civic Center Drive for an unincorporated parcel.
Permits for City of Larkspur addresses run through City of Larkspur Community Development, Building Division, City Hall, 400 Magnolia Avenue, second floor, Larkspur, CA 94939. Call (415) 927-5038. Email: building@cityoflarkspur.org. City site is cityoflarkspur.org. The City also handles building permits for incorporated Greenbrae addresses inside Larkspur city limits. Unincorporated Greenbrae and Kentfield lots that only sit next to Larkspur run through Marin County Building — a different office.
Corte Madera sits south. Kentfield sits northwest. Greenbrae sits north. Mill Valley sits southwest. San Rafael sits north. Highway 101 and the Larkspur Ferry Terminal sit on the east side. Text the street so the bid matches City of Larkspur for a city address — not a Corte Madera 94925 permit, and not County Building for a city lot.
Commercial work sits on Magnolia Avenue, Larkspur Landing Circle, Larkspur Plaza Drive, Doherty Drive, Bon Air Road, East Sir Francis Drake Boulevard, and Madrone Avenue. Occupied houses and open shops change the layout — not the stud spec.
The usual mismatch is treating a Magnolia Avenue tenant wall like a bedroom 2×4 — or hanging a Level 5 commercial finish on house framing that only needed wood hang-only. Interior metal studs do not hold the building up. Occupied houses and open shops need a clean layout, backing for cabinets and TVs, and a stud plane the finish can live with. Matching the spec still beats guessing the gauge. Send the plan sheet or a wide shot of the room. That photo decides wood hang-only vs new metal studs faster than a ZIP code.
