Mill Valley Framing From the Fairfield Shop
Ron Hogan Drywall has been family-owned since 1970. We are based in Fairfield — a south Marin run, not a Throckmorton storefront. Mill Valley is an incorporated city in Marin County — not Tam Valley, not Corte Madera, and not Sausalito. It has its own Building Division at City Hall, 26 Corte Madera Avenue. Street ZIP 94941 covers City of Mill Valley and also unincorporated Tamalpais Valley, Homestead Valley, Alto, Almonte, and Strawberry. 94942 is a Mill Valley PO Box. This page is steel / metal stud framing at City of Mill Valley 94941 addresses — Miller Avenue, Throckmorton Avenue, and East Blithedale. The street decides the bid.
Text “Mill Valley” 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 Mill Valley
Interior partition walls
Track, studs, and bracing for new rooms, office layouts, and non-load-bearing walls at City of Mill Valley addresses. This is the skeleton the board hangs on.
Miller and Throckmorton TIs
Restaurant, shop, office, and commercial build-outs on Miller Avenue, Throckmorton Avenue, and around Lytton Square when the drawing says steel studs. If the plan names metal, that is the bid. Commercial framing →
East Blithedale and Camino Alto interiors
Office, shop, and occupied-building partitions on East Blithedale Avenue, Camino Alto, and Corte Madera Avenue. Occupied buildings change the layout — not the stud spec.
Hillside house remodel partitions
New interior steel walls inside an existing Mill Valley house when the finish needs a straighter plane than bowed lumber. Wood structure stays wood unless the plan says otherwise. Narrow canyon streets change the layout — not the stud spec. 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 Mill Valley Job
| Stud | Use it when | Skip it when |
|---|---|---|
| Light-gauge metal (what we frame) | Miller Avenue TI, Throckmorton shop, rated walls, or a finish that needs a flat plane for Level 4 / Level 5 | You need beams, columns, or 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, restaurant TIs, or engineer notes | A simple closet that never needed the extra gauge |
| Wood studs | Most Mill Valley 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 |

Mill Valley Streets, ZIP, and Permits
Mill Valley is an incorporated city in Marin County — south Marin, on the slopes of Mount Tamalpais. This page uses street ZIP 94941. 94942 is a Mill Valley PO Box. Area codes are 415 and 628. Tam Valley, Homestead Valley, Alto, Almonte, and Strawberry also use 94941 and are unincorporated. Nearby Corte Madera uses 94925. Larkspur uses 94939. Sausalito uses 94965. Text the street so the bid matches City of Mill Valley Building Division — not Marin County Building at 3501 Civic Center Drive for a Tam Valley lot, not Town of Corte Madera Building at 300 Tamalpais Drive, not City of Larkspur Building at 400 Magnolia Avenue, and not City of Sausalito Building at 420 Litho Street.
Permits for City of Mill Valley addresses run through City of Mill Valley Building Division, City Hall, 26 Corte Madera Avenue, Mill Valley, CA 94941. Call (415) 388-4033. Email: building@cityofmillvalley.gov. City site is cityofmillvalley.gov. A 94941 mailing ZIP on Tamalpais Valley, Homestead Valley, Alto, Almonte, or Strawberry runs through Marin County Building — a different office. Greater Mill Valley is not the same as city limits.
Corte Madera sits east. Larkspur sits northeast. Sausalito sits south. Highway 101 sits east of downtown. Miller Avenue and Throckmorton Avenue are downtown. East Blithedale runs toward the freeway. Text the street so the bid matches City of Mill Valley for a city address — not a Tam Valley county permit, and not a Corte Madera 94925 permit.
Commercial work sits on Miller Avenue, Throckmorton Avenue, East Blithedale Avenue, Camino Alto, and Corte Madera Avenue. Occupied hillside houses and open shops change the layout — not the stud spec.
The usual mismatch is treating a Throckmorton shop 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.

Yes. Interior light-gauge metal stud framing in Mill Valley, CA from our Fairfield shop — partitions, Miller Avenue and Throckmorton TIs, East Blithedale interiors, hillside house walls, soffits, heavier-gauge spec walls, and frame-and-hang.
Is Mill Valley a city?

Is Tam Valley the same as Mill Valley?
No. Tamalpais Valley, Homestead Valley, Alto, Almonte, and Strawberry are unincorporated communities that share ZIP 94941 with the City of Mill Valley. Those lots use Marin County Building and Safety at 3501 Civic Center Drive — not this City of Mill Valley page.
Is this structural steel?
No. We frame interior light-gauge studs, track, headers, and soffits. Beams, columns, and structure that hold the building up are a different contractor.
Do Mill Valley houses use metal studs or wood?
Most house walls here are still wood. Metal wins on Miller and Throckmorton TIs, rated walls, and remodels that need a straighter plane for a smooth finish. If the drawing names the stud, that wins.
Can you frame a shop on Miller Avenue or Throckmorton?
Yes. Occupied retail, restaurant, office, and commercial tenant improvements on Miller Avenue, Throckmorton Avenue, and East Blithedale are a usual request — new partitions, soffits, and backing, then hang if the scope includes board.
