Kentfield Multifamily Exterior Siding & Windows Renovation

For a property manager, HOA board, or apartment owner in Kentfield, an exterior renovation is a different problem than it is for a homeowner. You're weighing a capital budget against deferred maintenance, coordinating around tenants or owners who live there every day, keeping the elevations consistent across a whole complex, and answering to Marin County — and, on many properties here, to an association's own architectural standards. Bay Area Siding Company handles that full scope: portfolio-scale re-siding and window replacement, planned and phased for occupied buildings.

We're based in Larkspur, minutes from Kentfield, and work across Marin. This page is for the decision-makers.

Why Kentfield multifamily and HOA exteriors need a real plan

The Ross Valley climate does not treat multi-unit buildings gently. Kentfield records one of the highest annual rainfall totals in the Bay Area, and the shaded, creek-valley setting keeps walls damp long after storms — so moisture damage that would be slow elsewhere tends to compound across many units at once. On a complex, deferred exterior maintenance rarely stays isolated to one wall; the same failing flashing detail or tired cladding shows up building after building. Addressing it as a planned program, rather than a string of emergency repairs, is almost always the lower lifetime cost.

For HOA-governed properties, there's the added dimension of architectural consistency — profiles, colors, and materials that have to match across the community and satisfy the association's design standards. And on the wooded parcels toward Kent Woodlands, wildfire exposure adds a code layer (below).

What we do for multi-unit properties

• Full re-siding across buildings — in fiber cement, engineered wood, vinyl, or CertainTeed lines, chosen for the building type, the exposure, budget, and long-term maintenance cost. On fire-exposed parcels we lead with noncombustible options.
• Window replacement at scale — across many units, coordinated for Title 24 energy compliance and consistent appearance, in the brands we install (Anlin, Milgard, Andersen, Marvin, Pella).
• Tenant-occupied phasing — sequencing by building, wing, or elevation so residents keep access, notice, and quiet hours, and no one loses use of their home longer than necessary.
• Moisture correction across the envelope — the water-resistive barrier and flashing work that actually stops the recurring damage, done consistently building to building.

Phasing and disruption — the part that decides the project

On an occupied property, the schedule is as important as the scope. We plan the work in phases so that tenant access, parking, and quiet hours are protected, notices go out ahead of each building, and units aren't opened up faster than they can be closed back in — which matters even more in a rainy valley, where an exposed wall can't sit open through a storm. For boards and managers, that predictability is often the difference between an approved project and a stalled one. We build the phasing plan around your occupancy and your budget cycle, not around our convenience.

Permits, code, and association review

Because Kentfield is unincorporated, permitting for multi-unit exterior work runs through the Marin County Community Development Agency, Building and Safety Division at the San Rafael Civic Center — not a city office. Window replacement is treated as an alteration under the Energy Code, so Title 24 compliance is part of the submittal; the exact targets depend on climate zone and code cycle, which we confirm at permit time rather than quoting fixed numbers.

For properties on the wooded slopes toward Kent Woodlands, wildfire exposure can bring California Building Code Chapter 7A into play. Where a parcel falls under a fire-hazard designation — and Cal Fire's updated Fire Hazard Severity Zone maps are moving through local review and adoption across Marin — Chapter 7A can shape which exterior materials and glazing are allowed. Applicability is parcel- and scope-specific, so we confirm it with the County per property rather than assuming a blanket rule. Where an HOA or association design review governs the community, we spec within its standards from the start.

Budget and long-term value

We bid after assessing the buildings, never online. The drivers on a multi-unit project are the number and size of buildings, unit count and access, material and window selections across the portfolio, how much concealed moisture damage the assessment turns up, the phasing plan your occupancy requires, and any County or association review. The value case is usually in the long term: a planned re-side and re-glaze with corrected flashing lowers recurring repair spend and protects the asset — and doing many units at once carries efficiencies a piecemeal approach can't.

Frequently asked questions

Can you work on our buildings while they're occupied? Yes — that's the norm for multifamily and HOA work. We phase by building, wing, or elevation, coordinate notices and access, respect quiet hours, and never open more wall than we can close before weather, which matters in this rainy valley. Residents keep use of their homes throughout.

Who issues the permits for our Kentfield property? The Marin County Community Development Agency's Building and Safety Division, because Kentfield is unincorporated. Window work carries Title 24 energy compliance as part of the submittal. We manage the permitting across the project.

Our complex is on the wooded slopes — does fire code affect the material choice? It can. Where a parcel falls under a fire-hazard designation, Chapter 7A may steer cladding and glazing toward noncombustible or ignition-resistant options. We confirm each property's designation and scope with Marin County and spec accordingly — and within any association design standards.

Can you keep the exterior consistent across all our buildings? Yes. Matching profiles, colors, and materials across a community — and meeting association architectural standards — is a core part of how we plan portfolio and HOA work.
