ADU Company in Westlake Village, CA
Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions across Westlake Village, CA. Most homes here were built between the late 1960s and mid-1980s on large lots, which means real square footage to work with, but also aging electrical panels and HOA architectural review committees that shape what gets approved. Our work starts with a written price and a clear path through both City and ARC requirements. Call (254) 602-5618 to talk through your lot.
Why Westlake Village Homes Are Different
Westlake Village is a master-planned community, and that planning never stopped. Virtually every neighborhood operates under an HOA with its own Architectural Review Committee, and California’s AB 670 says an HOA cannot flatly ban an ADU, but Westlake Village ARCs keep enforceable authority over materials, roof pitch, exterior colors, and massing. That creates a two-track approval process: the City of Westlake Village building permit plus separate ARC sign-off. Contractors who pull the city permit first and discover the ARC’s design standards second often eat months of redesign. We clear the ARC before the permit submission goes in, because the lakefront ARCs in particular care as much about sightlines as the city cares about setbacks.
Many parcels sit within or next to a High Fire Hazard Severity Zone, which triggers Chapter 7A ignition-resistant construction on new ADU structures. Exterior wall assemblies, vent covers, and roofing all carry different material requirements than a coastal project would. And the existing homes themselves, mostly ranch and two-story traditional builds with attached two- or three-car garages, often need a 100-amp panel upgraded before a garage conversion or ADU can pull real load. Every one of these details changes the price and the schedule, and we plan around them from the first site visit.
Our Main Westlake Village Services
The three most common calls we get in Westlake Village are home additions for growing families, garage conversions that turn underused square footage into rentable or in-law space, and detached ADUs in backyards that already have the room for one. Each has its own page below.
Home Addition Contractor in Westlake Village
A home addition in Westlake Village means matching rooflines and exterior materials to a house built decades ago, and it means walking the addition through the same ARC review that governs everything else on the property. We handle the structural work, the city permit, and the ARC package as one job, then build to a fixed written price. Home Addition Contractor in Westlake Village
Garage Conversion Contractor in Westlake Village
Garage conversions are the most common ADU path in Westlake Village because the footprint already exists and the ARC conversation is often simpler than a new detached build. The catch is that those original garages from the 1970s and 1980s frequently have post-and-beam framing that fights interior wall placement, and the 100-amp panels feeding them usually need an upgrade.

ADU Builders in Westlake Village
A detached ADU on a Westlake Village lot usually means a new structure in a backyard with real space, and that means Chapter 7A materials if the parcel is in a fire hazard zone and a rendering package the ARC will accept on the first pass. We match the build method and the materials to the lot, the budget, and the HOA’s published standards. ADU Builders in Westlake Village

What moves the number in Westlake Village is almost always the ARC layer plus the fire-zone materials if the parcel is in a High Fire Hazard Severity Zone. A project that clears the ARC on the first submission costs what we quoted; one that goes back for redesign costs more in both time and money. Our price is written before any work starts, and it does not change at the door.

FAQs About ADU Company in Westlake Village
Most Westlake Village homes are within a short drive of our LA dispatch office, and our crews schedule around your availability and any ARC hearing date. Call (254) 602-5618 and a live person will give you a real arrival window, not a voicemail loop.
Yes. We prepare the ARC package (renderings, materials, colors, roofline) and submit it before the city permit goes in, because Westlake Village ARCs routinely require changes that the city’s setback math alone would not. Getting that order right avoids months of redesign. Call (254) 602-5618 for specifics on your HOA.
No. Every project gets a written price before any work starts, and that number holds unless you change the scope. The Kingswell Guarantee covers it, and it includes a free return visit if the work fails within the 365-day guarantee period. Call (254) 602-5618 for a line-item estimate.

What Westlake Village Customers Say
"Built a backyard unit for my mother in law. They handled the permits, gave me a real timeline, and stuck to it within a few days. The written price is what we paid, which anyone who's done construction knows is rare."
- Dennis Fairchild"Garage conversion into a studio for our teenager. Honest about what was realistic and what wasn't, finished close to schedule, and cleaned up the site daily."
- Marcus Beaumont"I was nervous about adding on but they walked me through every step and every cost before we started. No surprise change orders halfway through like I'd heard horror stories about."
