Larkspur Multifamily Exterior Siding & Windows Renovation

Re-cladding or re-windowing a Larkspur apartment building, condominium association, or multi-unit portfolio is a different undertaking from a single-family re-side, and it's the job this page is about. Bay Area Siding Company is headquartered right here in Larkspur, on Magnolia Avenue, and works with property managers, HOA boards, and apartment owners on exterior renovation at scale: large-run siding replacement, building-wide window replacement, and the phasing, sequencing, and code coordination that occupied buildings demand. If you're planning a capital exterior project, this is the conversation to start.

What multifamily exterior work actually involves

On a multi-unit building the scope reaches well past the cladding itself:

• Portfolio-scale re-siding and window replacement across many units and elevations, specified for consistency and run as one coordinated program rather than a string of one-offs.
• Tenant-occupied phasing. Most Larkspur multifamily buildings can't be emptied for the work, so the sequence is built around occupancy — elevation by elevation or stack by stack — with clear resident notice, protected access and egress, and daily site security so people keep living there through the project.
• Minimized disruption. Staging, debris control, noise windows, and parking coordination get planned up front, because on an occupied building the logistics are half the job — and on the tight, sloped, or creekside lots common in Larkspur, staging takes real thought.
• Long-term maintenance economics. For an owner or board, the material decision is a cost-over-time decision. In this damp, marine climate, lower-maintenance and longer-lived claddings and windows change the reserve-study math, not just this year's budget.

HOA and architectural consistency

For a condominium association or HOA, uniformity across the property is often a governing requirement rather than a preference. We work from the association's architectural standards so that profiles, colors, and finishes read as one building — important where CC&Rs or design guidelines control the exterior, and where a phased or partial scope still has to match what's already up. Bringing the board a specified, consistent system up front tends to make approvals cleaner, and near the Magnolia Avenue historic district it also helps align with any design-review expectations the City may apply.

Code and fire compliance across many units

Multifamily buildings carry code obligations a single house doesn't, and in Larkspur wildfire adds a dimension. Buildings in the canyon and hillside neighborhoods carry real fire exposure, and Central Marin Fire adopted California's updated Fire Hazard Severity Zone maps in 2025. Where a property falls in a High or Very High zone or the Wildland-Urban Interface, Chapter 7A shapes what the exterior wall — and, for windows, the glazing — can be, generally favoring noncombustible or ignition-resistant assemblies, and applying that consistently across an entire multi-unit elevation is its own coordination task. Whether and how those provisions apply depends on the parcel's designation, the products specified, and the scope, so we confirm requirements with the City of Larkspur and Central Marin Fire rather than assume. A multi-unit project also means permitting at a scale that benefits from being planned as one submission. On any building, tear-off takes the old cladding off to the sheathing so the water-resistive barrier and flashing can be inspected before new work goes on.

Choosing materials at scale

The material shortlist for a multifamily building weighs durability, fire compliance, and lifetime maintenance heavily. Fiber cement and James Hardie are frequent choices for their noncombustibility and low upkeep — especially on canyon and hillside properties; CertainTeed offers a single-brand lineup spanning vinyl to fiber cement that can simplify specification across a portfolio; vinyl can suit budget-driven buildings in the flats where fire rules don't govern. We help boards and owners weigh these against the reserve budget and the maintenance horizon. Windows can be planned in the same program — see the general approach on the Larkspur window replacement page.

Budget and planning

A multifamily bid is built around the unit count, the number of buildings and elevations, story height and access — which drives staging and lift requirements on sloped or creekside sites — the materials and window specifications, the phasing plan, and what condition assessment and tear-off reveal in the substrate. We scope it as a program with a defined sequence and schedule, so the board or owner can plan cash flow and resident communication around real milestones. Because these are capital projects, the long-term maintenance savings of the specified system are part of the numbers we bring you.

FAQ

Can the work be done while our building stays occupied? Yes — most multifamily exterior renovations are done on occupied buildings. We phase the work by elevation or stack, keep access and egress protected, give residents advance notice, and sequence it to minimize disruption to daily life.

Our HOA requires a consistent look across the property. Can you match that? That's standard for association work. We specify profiles, colors, and finishes to the HOA's architectural standards so the whole property reads as one building, including on phased or partial scopes governed by your CC&Rs.

Our building is up a Larkspur canyon. How does that affect the project? Canyon and hillside parcels may fall in a High or Very High fire zone or the WUI, where exterior-wall and glazing rules favor noncombustible or ignition-resistant assemblies, applied across the whole building. We confirm the parcel's designation with the City of Larkspur and Central Marin Fire and specify a compliant, consistent system across all affected elevations.

How do you handle permitting for a multi-unit project? Multifamily work benefits from being planned as a coordinated submission to the City of Larkspur rather than piecemeal. We build the permitting and inspection sequence into the project schedule so it aligns with the phasing plan.
