Re-cladding or re-glazing an occupied building is a different job than a single-family re-side, and it needs a contractor who treats it that way. Bay Area Siding Company works with Palo Alto property managers, HOA boards, and apartment owners on exterior renovation across whole buildings and portfolios — siding replacement, window replacement, and the flashing and weatherproofing that tie them together — planned around tenants, budgets, and the city's approval process rather than dropped on top of them.

Built around occupied buildings

The hard part of multifamily exterior work isn't the cladding — it's doing it with people living there. Our planning starts from that constraint:

• Phased scheduling by building, wing, or elevation so units and common areas stay usable and parking and access stay workable.
• Tenant communication — clear notice of what happens on which units and when, so residents aren't surprised by crews at a window or a wrapped wall.
• Site control — staging, debris, and daily cleanup managed so walkways, entries, and egress stay safe and open throughout.
• Predictable sequencing so a large project moves at a pace owners and boards can plan and budget against.

For a decision-maker answerable to residents or an HOA membership, that predictability is often worth as much as the construction itself.

Materials and windows chosen for the long run

On a portfolio, the total cost of ownership matters more than the sticker price of any one material. We help owners and boards weigh options against maintenance and lifespan:

• Fiber cement (including James Hardie) — noncombustible and low-maintenance, often the default for larger buildings where repainting every wall on a short cycle is costly and where fire performance matters.
• LP SmartSide — engineered wood, lighter and impact-resistant, where a warmer wood look is wanted.
• Vinyl and CertainTeed insulated lines — where budget leads and maintenance savings are the priority.
• Replacement windows — Anlin, Milgard, Andersen, Marvin, and Pella — specced consistently across units for uniform appearance, energy performance, and warranty. See the window replacement hub.

Because windows and siding meet at the flashing, having one contractor own both details removes the finger-pointing that plagues split scopes and keeps the building's weatherproofing continuous.

Architectural consistency and the Palo Alto context

HOAs and condo associations usually carry architectural standards, and a multi-building re-side has to land uniform across every elevation — consistent profile, color, and trim. We spec to a single standard so the finished project reads as one building, not a patchwork. Palo Alto's housing character adds a wrinkle: in neighborhoods with Eichler and mid-century buildings, the city's advisory Eichler Neighborhood Design Guidelines encourage retaining the original look, and preserving that rhythm across a multi-unit property is a design decision we plan for. We coordinate with your board's standards and the city's process together.

Permits, fire, and code across many units

Exterior work at this scale runs through the City of Palo Alto's permitting, and multifamily buildings carry code considerations single-family homes don't. Re-siding requires a building permit; window replacement generally triggers a permit when the frame size or shape is altered, when flashing is altered, or when it's part of another permitted project, with Title 24 energy documentation part of the submittal (Palo Alto is in California Energy Code Climate Zone 4). Where openings are altered, egress and safety-glazing requirements apply per unit. And for buildings along the western foothill edge inside a mapped Wildland-Urban Interface or Fire Hazard Severity Zone, Chapter 7A of the California Building Code may bear on the exterior assemblies — noncombustible fiber cement is a commonly used compliant option, but applicability depends on the parcel and scope, which we confirm with the AHJ before speccing. We handle the permitting for the full scope so the paperwork keeps pace with the work.

What drives the cost

Multifamily projects are bid after a site assessment, and the drivers are building count and total wall and opening area; number of stories and access (upper floors, tight lot lines, and limited staging add cost); the material and window specification; how much substrate and flashing repair surfaces once cladding is off; the phasing plan and tenant-coordination requirements; and the permit and any design-review scope. We build a scope and sequence you can budget against rather than a single blind number.

FAQ

Can you re-side or re-window our building without moving tenants out? Yes — that's the norm. We phase the work by building, wing, or elevation and coordinate notice so units and common areas stay usable and egress stays open throughout.

Can you keep the look consistent across all the units and buildings? Yes. We spec to a single architectural standard — profile, color, trim, and window line — so the finished property reads as one cohesive building and meets your HOA or association standards.

How do fire-zone rules affect a multifamily building in Palo Alto? For a building on a foothill parcel in a mapped Fire Hazard Severity Zone, Chapter 7A may govern the exterior assemblies, and noncombustible fiber cement is a common compliant choice. Applicability depends on the parcel and scope, which we confirm with the City before speccing.

Do you handle the permits for a multi-unit project? Yes. We manage the City of Palo Alto permitting for the full scope — siding, windows, and the Title 24 energy documentation — so approvals keep pace with construction.
