Lafayette Multifamily Exterior Siding & Windows Renovation

Re-cladding a multi-building property is a different job than re-siding a single house, and it's run by different people — property managers weighing a capital budget, HOA boards answerable to owners, apartment owners protecting a rent roll. Bay Area Siding Company takes on multifamily and community-association exterior work in Lafayette: portfolio-scale siding replacement and window replacement, planned and phased so the buildings stay livable and the schedule stays predictable. If you're responsible for the envelope of an apartment community, a condo or townhome association, or a small portfolio in Lafayette, this page is for you.

What large-scale work demands that single-family doesn't

• Tenant-occupied phasing. People live and work behind these walls. We sequence the job building by building and elevation by elevation, with notice and access coordination, so units stay occupied and disruption is contained to a known window rather than sprawling across the property.
• Predictable scheduling and communication. Boards and managers need dates they can hold and report on. We plan the phases, staging, and access up front and keep a single point of contact through the project.
• Budget and life-cycle thinking. A reserve study or a capital plan doesn't want surprises. We scope the work so the numbers are defensible, and we talk honestly about long-term maintenance economics — where a higher-durability, lower-upkeep cladding lowers the total cost of ownership across a portfolio versus a cheaper material that comes back around sooner.
• Architectural consistency. For an HOA, uniformity is often a governing-document requirement. We work to a single specification across buildings — matching profile, color, and detailing — so the community reads as one coherent property when the work is done.
• Compliance across many units. Permitting, inspection, and code apply to every building, and a large property multiplies the coordination. We manage the submittals and inspections rather than leaving that to the board.

The Lafayette specifics that shape a multifamily project

Lafayette's building department administers permits through its Planning & Building Department, with plan review and inspection contracted to the Contra Costa County Building Inspection Division — the same authority for a fourplex or a townhome association as for a single home, but at portfolio scale the inspection coordination is a project in itself. We handle it as part of the job.

Fire is the other Lafayette-specific factor, and it's genuinely parcel-dependent. A large share of the city sits in mapped Fire Hazard Severity Zones — mostly High, with a smaller Very High area on the wooded hillsides — and a multi-building property can straddle more than one designation. On regulated parcels, noncombustible cladding such as fiber cement may be the appropriate choice and a fire-rated assembly may be required, but whether it applies depends on each building's parcel and the scope of work. We confirm the requirements with the City and the county across the whole property rather than assume a single answer for it, and we build the compliance into the specification.

Lafayette's climate adds the practical case for durable materials at scale: shaded, canyon-facing elevations that hold moisture, and long, hot inland summers. Across many units, the walls that fail first are the damp, north- and downhill-facing ones — and a cladding chosen for that reality pays back over the life of the property.

Siding and windows, planned together

Many envelope projects are the moment to address windows alongside siding — it's more efficient to integrate flashing and openings once than to disturb the wall twice. We handle both: portfolio re-siding and window replacement across the buildings, retrofit or new-construction installs depending on the openings, with Title 24 energy compliance handled where the work requires a permit. Keeping siding and windows on one coordinated schedule is usually the lower-disruption, lower-cost path for a community.

What we install

We work in the full range so the specification can be matched to the property and its parcels: fiber cement and James Hardie where fire performance and low maintenance lead, vinyl and insulated CertainTeed lines where maintenance economics dominate outside the fire zones, and LP SmartSide where a wood look is wanted. On the window side we install Anlin, Milgard, Andersen, Marvin, and Pella — spec'd to the community's standard.

What drives the cost

We bid from the property, not a chart. The drivers on a multifamily job are the number of buildings and units, the total wall and opening count, the material specification, how much concealed substrate repair surfaces once walls are open, the phasing and access constraints of an occupied property, staging on hillside or tight sites, and any fire-zone assembly detailing across the parcels. A walkthrough and a look at your drawings is how we build a defensible number.

FAQ

Can you re-side our community while it stays occupied? Yes — that's the norm for this work. We phase the project building by building and elevation by elevation, coordinate access and notice with management, and contain the disruption to a scheduled window rather than the whole property at once.

Our property spans different fire-zone designations — how do you handle that? We confirm each building's parcel designation and scope with the City of Lafayette and the Contra Costa County Building Inspection Division, then build the appropriate compliance — including noncombustible cladding and fire-rated assemblies where required — into a specification that still keeps the community architecturally consistent.

Can you keep every building matching for our HOA? Yes. We work to a single specification across the property — profile, color, and detailing — so the community reads as one coherent whole, which is usually a governing-document requirement as well as a curb-appeal one.

Do you handle the permitting and inspections for all the buildings? Yes. Permits run through the City of Lafayette Planning & Building Department with inspection contracted to the Contra Costa County Building Inspection Division. We manage the submittals and coordinate inspections across the property.
