San Bruno Multifamily Exterior Siding & Windows Renovation

Bay Area Siding Company re-sides and replaces windows on multifamily and small commercial buildings in San Bruno. We work for property managers, HOA boards, and apartment owners who need an exterior renewed while residents keep living inside. We're a Larkspur-based siding and window contractor that works across the Peninsula. On a multi-unit job we handle the scope, the permit with the city, sequencing around occupied units, and the building-envelope details that decide whether the new exterior lasts.

What makes a San Bruno multifamily exterior different

Three local conditions shape these projects more than anything else.

Weather comes through the gap. San Bruno sits where marine air, fog, and afternoon wind push inland from the coast. On a two- or three-story building, the windward elevations take wind-driven rain and damp mornings year after year.

• Where failures show up: in the details. Look at flashing at window heads, joints at floor lines, deck and balcony ledgers, and the bottom courses near grade.
• What it means for your bid: a good scope puts as much weight on water management as on the siding product itself.

Many units sit under SFO flight paths. San Bruno lies within the San Francisco International Airport influence area, and aircraft noise is part of daily life for many residents.

• Why it matters for windows: glass choice has a real effect on tenant comfort.
• What we can do: we can specify sound-rated glass packages, such as laminated glass or panes of differing thickness, on the elevations and units where noise matters most.
• Why it matters to owners: quieter units help with tenant satisfaction.

Fire-hazard designation is parcel by parcel. Most of San Bruno is not in a mapped high-fire zone. However, the city has adopted the state's updated Fire Hazard Severity Zone map, and properties along the western hills and open-space edges can be designated.

• If your property is designated: California Building Code Chapter 7A can govern exterior wall coverings and certain window and vent assemblies on the work being done.
• Other factors: construction type and occupancy add their own layer.
• How we handle it: we check the address and confirm requirements with the city before speccing materials. We don't assume either way.

Built for boards, managers, and owners

A single-family homeowner makes a decision in one conversation. Your process involves reserve studies, board votes, owner notices, tenant communication, and competing bids. We structure our work to fit that process.

Scopes you can compare

We write scopes by building and by elevation, so a board can compare bids line by line. Each scope covers:

• Cladding removal
• Water-resistive barrier and flashing
• Trim and sealants
• Windows, if included
• Paint or finish

If the reserve budget calls for phasing the work across fiscal years, we can break the scope into logical stages. For example, the worst-exposed elevations can go first and the sheltered sides later.

Phasing around occupied units

Most multifamily exteriors in San Bruno stay occupied during the work. We plan the sequence so each unit's disruption is short and predictable:

• Staged work: we work a stack or elevation at a time rather than opening the whole building at once.
• Daily close-up: we close up openings at the end of each day.
• Access plans: we coordinate access for window work inside units.
• Resident notices: we give you a schedule you can pass along to residents.

For sites near busy streets, near the BART and Caltrain stations, or with tight parking, we also plan staging, material deliveries, and debris removal so common areas stay usable.

Uniform appearance across the property

HOAs usually need the finished exterior to look consistent from building to building and to match what the CC&Rs and architectural guidelines allow. We help boards choose a profile, reveal, and color palette that can be repeated across every structure. We also think about how the property will be maintained years from now, not just how it looks at completion.

What a proper re-side involves

Siding on older multifamily buildings in San Bruno often covers problems that don't show from the parking lot. Much of the city was built out in the postwar decades, and many older buildings still have original wood, T1-11 panel siding, or aged stucco.

In a full re-side:

• Removal: we take the cladding off down to the sheathing and substrate.
• Inspection: we check the water-resistive barrier and flashing. On buildings of that era, the barrier is sometimes missing or deteriorated.
• Repairs: we find damaged sheathing, especially around windows, decks, and roof-to-wall intersections, and repair it before new material goes on.
• When framing gets involved: framing is only exposed where the sheathing itself has failed and must come out. We flag that as a separate, documented condition so there are no surprises in the change-order process.

Covering old siding with new material skips all of this. On a building your association or ownership plans to hold for decades, that's usually a false economy.

Coordinating with balcony and elevated-element inspections

California law requires periodic inspection of balconies, decks, and other exterior elevated elements on many multifamily buildings. Those inspections are performed by qualified licensed professionals, not by us. If your building has recent findings, or an inspection coming up, a re-siding project is a sensible time to coordinate the work. The cladding and flashing around those elements get opened anyway, so bring your inspector's report to the site walk.

Material and window options for multi-unit buildings

We install several siding systems. The right choice depends on your budget, exposure, maintenance plan, and any fire-zone requirements for the parcel.

• Fiber cement, including James Hardie:
  • Noncombustible.
  • Resists rot and moisture.
  • Holds paint well in damp coastal air.
  • A common choice for long-hold properties.
• LP SmartSide: engineered wood with a real-wood texture. It is lighter to handle and needs periodic repainting.
• Vinyl and CertainTeed lines: budget-conscious options with low painting maintenance.
• Wood: for properties where matching existing character matters more than keeping maintenance low.

For windows, see our window replacement hub.

• Brands we install: Milgard, Anlin, Andersen, Marvin, Pella, and aluminum windows.
• Energy paperwork: in San Bruno, window replacement is treated as an alteration under the Energy Code, so Title 24 fenestration documentation goes in with the permit. Performance values vary by climate zone and code cycle, so we confirm the numbers in effect at permit time.
• Install methods:
  • Retrofit (insert) installs keep the existing frame and minimize disruption inside units.
  • New-construction (full-frame) installs let the flashing be fully renewed. They are the better choice where there's been rot or water intrusion.

For single-family owners in your community, our San Bruno siding replacement and window replacement pages cover the homeowner side of the same decisions.

Permits in San Bruno

Siding and stucco work, and window replacement, require a building permit through the City of San Bruno's Community & Economic Development Department, Building Division. We prepare and pull the permit as part of the job and schedule inspections around the phasing plan. Some multifamily projects need extra review depending on:

• The building's construction type
• The extent of the work
• Whether the parcel sits in a designated fire-hazard zone

We confirm these with the Building Division during scoping.

What drives the budget

We don't publish prices, because multifamily costs depend heavily on the site. The main drivers are:

• Size and access: building height, and whether the work needs scaffolding or lifts.
• Wall area and complexity: total wall area and how many corners, balconies, and penetrations it includes.
• Hidden repairs: the amount of sheathing and flashing repair uncovered once cladding comes off.
• Materials: the siding material and finish you choose.
• Windows: window count, glass package (sound-rated glass adds cost), and whether the installs are retrofit or full-frame.
• Phasing: schedule constraints for occupied units.
• Code requirements: any fire-zone requirements for the parcel.

A detailed scope up front narrows the range of unknowns before your board votes. You can see examples of our exterior work on the projects page.

FAQs

Can residents stay in their units during the work? In most cases, yes. We phase by elevation or building, close up openings daily, and give you a schedule to share with residents. Window replacement needs brief interior access to each unit, and we coordinate that with management.

Is our San Bruno property in a fire hazard zone, and does that change the materials? Most of the city isn't in a mapped zone. Properties along the western hills and open-space edges can be, under the state map the city has adopted. If your parcel is designated, Chapter 7A can affect the wall covering and certain window and vent choices on the altered work. We verify your address and confirm with the city before specifying.

Can the new windows cut aircraft noise for tenants? Glass selection makes a meaningful difference in San Bruno. Laminated glass and dual-pane units with panes of differing thickness perform better against noise than older single-pane windows. We can target the most-affected units or elevations if you're balancing budget.

Can the project be split across budget years? Yes. We can break the scope into phases, typically starting with the most weather-exposed elevations. Each phase is priced so it fits your reserve plan.
