Re-cladding or re-glazing an occupied apartment community, condo complex, or HOA-governed development is a different project from a single-family re-side — and it's run differently. The stakes are tenant disruption, board and owner sign-off, budget predictability across dozens or hundreds of units, and code compliance at scale. Bay Area Siding Company, a Larkspur-based siding and window contractor working throughout the South Bay, takes on multifamily and commercial exterior renovation for the property managers, HOA boards, and apartment owners who carry those stakes.

Milpitas's multifamily stock is aging into this work

Milpitas grew fast after the mid-1950s, and its garden apartments, condo conversions, and townhome communities have aged alongside its single-family tracts. A great deal of that stock is now carrying original or first-generation cladding — wood, hardboard, T1-11, or early stucco — and early or single-pane glazing, all of it at or past service life. For an owner or board, the question stops being whether to renovate and becomes how to phase and fund it. That's the conversation we're built for.

What running it at scale actually requires

• Tenant-occupied phasing. We sequence buildings and elevations so residents keep access, parking, and quiet hours as much as possible, with clear notice windows and staging that doesn't blockade the property. Occupied work is a scheduling discipline as much as a construction one.
• Consistency across the property. Whether it's an HOA architectural standard or an owner's brand look, the material, profile, and color have to read the same across every building. We spec once and hold it across the phases.
• Budget and long-term cost. A portfolio re-side is a capital decision. We help you weigh up-front material cost against decade-out maintenance — fiber cement, for instance, carries a higher install cost but far lower repaint and repair overhead than the organic cladding it usually replaces, which matters when you multiply it across a complex.
• Code compliance across many units. Window replacement at scale means Title 24 fenestration compliance on every opening; re-siding means getting the water-resistive barrier and flashing right building by building. We carry the permitting.

Materials and windows for a Milpitas portfolio

The material logic is the same as single-family, weighted toward durability and low lifecycle cost because you're maintaining it at scale:

• Fiber cement and James Hardie — noncombustible, low-maintenance, the common choice for owners optimizing long-term cost
• LP SmartSide — engineered wood where a warmer look is wanted with better durability than the original
• Vinyl and CertainTeed lines where budget leads
• Window replacement across the property — we install Milgard, Anlin, Andersen, Marvin, and Pella, and match the line to the spec and budget

The fire consideration, per parcel

Most Milpitas multifamily sits on the flat valley floor, outside any fire mapping. But properties along the eastern hill edge can include parcels that fall inside a fire-hazard zone under Santa Clara County's updated 2025 maps, and where that designation applies, noncombustible cladding and compliant assemblies come into play. It's parcel- and scope-specific — we confirm each property's status and what the AHJ requires rather than applying a blanket rule across a portfolio.

Permitting and the wall behind

Exterior work in Milpitas is permitted through the City's Office of Building Safety, and we pull and carry the permits across the phases. On every building, the value of a full tear-off is the same: removing the old cladding to the sheathing and substrate — not the framing — lets us confirm the water-resistive barrier and correct the flashing at windows, doors, and penetrations. On stock of this era, that flashing and building paper is frequently spent, and covering over it just hides the problem and defers a bigger bill. Framing repair only enters where the sheathing itself has rotted.

How we scope a portfolio bid

There's no online quote for work like this. We walk the property, assess representative buildings, and build a scope and phasing plan around the material, the number of buildings and elevations, the window count, concealed-condition risk, HOA or ownership standards, and your budget and timeline. You get a written scope, a phasing schedule, and a single point of contact. See finished exteriors in our project gallery, read about our South Bay service area, and note that we also handle single-family window replacement and siding replacement in the city.

FAQ

Can you work on our apartments while they're occupied? Yes — the majority of our multifamily work is tenant-occupied. We phase by building and elevation, coordinate notice and access with your management, and stage to keep parking and entries usable. Minimizing disruption is part of the plan, not an afterthought.

How do you keep the look consistent across an HOA property? We spec the material, profile, and color to your architectural standard once and hold it across every phase and building, and we help with any board submittal or approval detail. Consistency is a requirement we design the project around.

Does a fire-hazard zone affect our Milpitas property? Only if the property includes parcels along the eastern hill edge that fall in a fire-hazard zone under the county's 2025 maps. Most Milpitas multifamily is valley floor and outside those zones. We confirm each property's status and the AHJ requirement before speccing materials.

Do you handle both siding and windows in one project? Yes. Combining re-siding and window replacement lets us sequence the flashing correctly where the two meet and consolidate the disruption into one mobilization — often the more economical path for a portfolio.
