ADU Company in West Hills, CA
Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions in West Hills, CA – a San Fernando Valley community where the housing stock, the heat, and the fire-hazard terrain all shape how a project should be designed and priced. Most homes here are post-WWII ranch-style builds from the 1950s through the 1970s, sitting on lots of 8,000 to 12,000 square feet that give homeowners real options for adding living space. Call (254) 602-5618 to talk through what’s possible on your specific West Hills lot.
Why West Hills Homes Are Different
West Hills sits at the western edge of the San Fernando Valley, pressed against the Simi Hills. That geography means two things for anyone planning an ADU or home addition here. First, summer temperatures regularly hit 100°F to 108°F, and dry Santa Ana winds sweep through every fall. Any attached or detached living space needs serious insulation and HVAC sizing – mini-split systems sized for genuine heat gain, not the mild-coast assumptions a contractor from outside the Valley might bring. Second, the hillside tracts that climb toward the Simi Hills fall inside the City of Los Angeles’s Very High Fire Hazard Severity Zone. The Woolsey Fire in 2018 burned through the northern and western edges of this community, and that experience still shapes local permitting requirements. Homes in VHFHSZ parcels face Chapter 7A wildfire-resistant construction standards: Class A roofing, ember-resistant vents, ignition-resistant siding, and fire-rated eaves. Those requirements can add $15,000 to $30,000 to a detached ADU or substantial garage conversion, and contractors quoting from outside West Hills routinely miss them until the plans come back rejected.
We’ve seen the sequencing problems this creates. A detached ADU just 500 feet uphill from an identical lot on the valley floor can trigger full Chapter 7A requirements, including ember-resistant attic vents that have to go in before the roof deck gets sheeted – a step that surprises framing crews who’ve never worked a VHFHSZ jobsite. West Hills lots are also unusually generous for the City of Los Angeles, which means detached backyard ADUs and garage conversions are setback-feasible on a high percentage of properties. The tradeoffs are different here, and they should be on the table before you commit to a design.
Our Main West Hills Services
West Hills homeowners most often call us about three ways to add living space on an existing lot: a full home addition, a garage conversion, or a detached ADU. Each has its own page for West Hills, with local pricing and the specific fire-zone and setback realities that apply.
Home Addition Contractor in West Hills
Home additions in West Hills usually mean extending a ranch-style house into its wide rear yard or adding a second story onto a single-level floor plan. The lot sizes here make rear additions feasible on many properties, but hillside lots and VHFHSZ parcels can change the wall and roof assembly requirements quickly. We handle the design, structural work, and Chapter 7A compliance as one scope – so the fire-resistant details are in the price from the start, not a change order later. See Home Addition Contractor in West Hills for full local pricing and a walk through how additions on West Hills lots typically come together.
Garage Conversion Contractor in West Hills
West Hills homes from the 1950s through the 1970s almost universally have attached two-car garages, and converting that existing footprint into a studio or one-bedroom living space is often the fastest way to add rental income or space for family. The catch in West Hills is fire-zone compliance: if your parcel is in the VHFHSZ, a garage conversion that changes the building envelope can trigger Chapter 7A siding, vent, and eave requirements that a valley-floor conversion would never face. We price those in before work starts. See Garage Conversion Contractor in West Hills for specific garage-conversion costs and the West Hills permit path.
ADU Builders in West Hills
Detached ADUs in West Hills go into backyards that are large enough to hold them without fighting setbacks – a real advantage compared to much of Los Angeles. But hillside fire-zone requirements change everything: a prefab or panelized ADU that’s simple on paper can need ignition-resistant exterior assemblies and fire-rated eaves once the parcel’s hazard status is checked. We work with manufacturers like Cover, Dvele, and Mighty Buildings, matching each unit to the lot’s actual Chapter 7A obligations rather than assuming a standard Vallejo spec. See ADU Builders in West Hills for full ADU pricing and the brands we recommend for West Hills parcels.

We put the full written price in front of you before any work starts, with no price changes at the door.

Yes, if your parcel falls inside the City of Los Angeles Very High Fire Hazard Severity Zone, and much of the hillside portion of West Hills does. We pull the hazard-zone status before we price your project, so Chapter 7A costs are in your written quote from the beginning, not added later.
No. Every West Hills project gets a written price before any work begins, and that number doesn’t change at the door or mid-job unless you change the scope. If we uncover a fire-zone requirement we missed, that’s on us to resolve, not a surprise line item for you.
