Fairfax Multifamily Exterior Siding & Windows Renovation

For property managers, HOA boards, and apartment owners in Fairfax, an exterior renovation is a different animal than a single-family re-side. You're balancing a budget across many units, keeping tenants or owners in place while the work happens, holding a consistent look across a complex, and — in this town more than most — meeting a fire code that reaches every wall. Bay Area Siding Company handles portfolio-scale re-siding and window replacement across Marin, and we scope multifamily work around those realities from the first walkthrough.

What large-scale exterior work involves here

The fundamentals don't change with unit count — tear-off to the sheathing, inspect and correct the water-resistive barrier and flashing, install cladding or windows to spec — but the logistics and stakes multiply. On a Fairfax property the recurring themes are:

• Fire compliance across every unit. This is the defining Fairfax factor for multifamily. Much of the town sits in a Fire Hazard Severity Zone or the wildland-urban interface, and Fairfax has adopted the California WUI Code (municipal code § 8.06.011). Where those rules and Chapter 7A apply, exterior walls and openings across the whole property generally need noncombustible or ignition-resistant materials — and for a board or owner, a coordinated re-side is often the moment to bring an aging complex into line rather than doing it piecemeal. Applicability turns on the parcel's designation and the scope of work, which we confirm with the Town of Fairfax before speccing the program.
• Tenant- and owner-occupied phasing. Buildings stay occupied. We sequence the work building-by-building or elevation-by-elevation, keep egress and access clear, communicate schedules ahead, and protect landscaping and parking — so residents aren't living inside a demolition zone for months.
• Architectural consistency. For an HOA, matching profile, color, and detail across every unit is often the whole point. We spec one system across the property and document it so future repairs match.
• Long-term maintenance economics. For an owner or board, the material decision is a decades-long line item. Moving an older complex to fiber cement, for instance, trades a higher upfront cost for far less repainting and rot repair across many units — the kind of math that pencils out over a hold period.

Material strategy across a portfolio

The same product logic that applies to a single home applies at scale, with durability and maintenance weighted more heavily because they multiply across units:

• Fiber cement (category / James Hardie) is usually the multifamily default in Fairfax — noncombustible for the fire code, rot-resistant for the damp canopy, and low-repaint across many walls.
• Vinyl can suit properties on parcels outside the fire rules where budget leads, though it's off the table on designated hazard-zone parcels.
• LP SmartSide offers a wood look with less upkeep than solid wood, where the parcel and scope allow it.

Windows follow the same path — energy-compliant, and fire-zone glazing (dual-pane with a tempered pane, or a rated assembly) where Chapter 7A applies. We install Anlin, Milgard, Andersen, Marvin, and Pella — Milgard and Anlin in particular scale well across many identical openings.

Permitting, process, and budgeting

Fairfax requires a construction permit for regulated exterior work, and many projects also route through the Town's Design Review Board — a step that carries real weight on a visible multifamily property, so we engage the Town early with the proposed system. We provide a written scope and a phasing plan, sequence the work to keep the property livable, and coordinate with your management on resident notice. Budget drivers at scale: total wall and opening area, the number of buildings and stories, hillside and canyon access, how much concealed rot surfaces at tear-off across an older complex, the material and glazing package, fire-zone requirements, and the phasing schedule you need.

Frequently asked questions

Can you work on our property while it stays occupied? Yes. We phase multifamily work — by building, by elevation, or by wing — and coordinate schedules and resident notice with your management so units stay accessible and the property stays livable throughout.

How does the fire code affect a whole complex in Fairfax? Where a property sits in a Fire Hazard Severity Zone or WUI area and Chapter 7A and the Town's WUI Code apply, exterior walls and openings across the property generally need noncombustible or ignition-resistant materials. A coordinated re-side is often the practical moment to bring an older complex up to that standard. We confirm what applies to your parcels and scope with the Town before speccing.

Can you keep every unit matching for our HOA? Yes — that's a core part of multifamily work. We spec one cladding and window system across the community and document it so the look stays consistent and future repairs match.

Do you provide a written scope and phasing plan for board approval? Yes. We give you a written scope, material spec, and phasing plan you can take to a board or ownership group, and we handle Town permitting and any Design Review submittal.
