Fielding ADU Builders works inside the Garrison Partners family, and our Garage Conversion Contractor team has handled conversions on hillside lots, flatland tracts, and equestrian-zoned properties throughout Agoura Hills. We know where the post-tension slabs run thick, which streets back into Fire Hazard Severity Zones, and what the plan-check counter asks for before they’ll stamp a change-of-occupancy permit. That local knowledge shows up in the price and the schedule, not as a line item, because it keeps the job from stalling.
Why Fielding ADU Builders Is Agoura Hills’s Preferred Garage Conversion Contractor Company
Reed Calloway leads our conversion team, and he’s walked more Agoura Hills garages than most people have walked Kanan Road. Homeowners here don’t call us because they found the cheapest bid. They call because they’ve already dealt with a contractor who missed the schedule, moved the price at the door, or left the permit board blank. We price the job in writing before work starts, and that number doesn’t move unless you change the scope in writing.
Our reputation in Agoura Hills rests on the Garrison Standard, which has been in force since 2006. That means every project gets a written one-year guarantee. If something fails inside 365 days, we come back and make it right at no charge. No phone tree, no argument about whose fault it is. The crew shows up background-checked and uniformed, you know exactly who’s on your property, and a live person answers our phone 24 hours a day, seven days a week.
For Agoura Hills specifically, that matters because most garage conversions here are reviewed as new dwelling units, not remodels. The City of Agoura Hills plan-check process pulls fire authority review on lots that back into the Very High Fire Hazard Severity Zone. A contractor who doesn’t plan for that gets a stop-order and a rewrite. We build it into the estimate from day one.
Garage Conversion ADU in Agoura Hills
A garage conversion ADU in Agoura Hills turns an attached or detached garage into a legal, separately rentable dwelling unit with its own kitchen, bath, and entrance. Most attached garage ADUs here run $105,000 to $185,000, and detached conversions land between $110,000 and $175,000 depending on whether the existing structure can be reinforced or has to come down. A homeowner wants this when the garage is dead space, the lot is too small for a backyard unit, and the rental income pencils out against the construction cost.
Attached Garage Conversions
An attached conversion reuses the existing garage shell and ties into the house’s systems, which usually saves money on foundation and roof work. In Agoura Hills, the catch on many hillside lots is the post-tension slab under the garage floor. Core-drilling for a new bathroom wet wall has to be mapped against the tensioned cables before the saw touches concrete. We locate the cables first, every time.
Detached Garage Conversions
A detached garage becomes its own structure with separate utilities and a separate address. On Agoura Hills lots that front equestrian easements or sit back from the street, the setback rules still apply the same way, but the fire review gets stricter the closer the structure sits to wildland brush. We price ignition-resistant eave and vent detailing into detached jobs up front, not as a change order.
Garage Apartment Conversion in Agoura Hills
A garage apartment conversion in Agoura Hills creates a self-contained living space, often for a family member, a caregiver, or a long-term tenant, with a full bath and a real kitchen. These jobs typically run $115,000 to $175,000 in Agoura Hills before permit fees because the city reviews them as new dwelling units with fire-rated separation from the main house if attached. Homeowners choose this over a simple bedroom conversion when the unit needs its own entrance, its own meter, and its own legal status.
Garage to Living Space
When the goal is a media room, office, or kids’ playroom without a kitchen, the scope shrinks and the price drops into the $75,000 to $110,000 range. But in Agoura Hills, even a non-rentable conversion on a fire-zone lot has to meet ignition-resistant exterior standards if the garage walls face the hillside. That’s a real cost driver people miss on their own estimates.
Garage to Bedroom
A garage-to-bedroom conversion works when the house needs one more private room and the lot can’t take an Agoura Hills Room Addition Contractor addition. We insulate the slab, reframe the garage door opening, run HVAC, and finish the space to match the house. Expect $65,000 to $95,000 in Agoura Hills, and expect the permit to hinge on egress windows and smoke detection hardwiring rather than square footage.
Trusted Brands We Service in Agoura Hills
We build garage conversions as conventional stick-frame work, and we also work directly with prefab and modular ADU platforms when the lot and budget call for it. That includes Abodu and Dvele panels, which some Agoura Hills homeowners prefer because the wall assemblies arrive with fire-rated sheathing already specified and ready for the fire authority review. If the project calls for a simpler approach, we also frame with James Hardie siding on the exterior and conventional lumber inside. We don’t push one system. We match the method to your lot, your setback, and the number you approved.
Common Garage Conversion Contractor Problems We See in Agoura Hills Homes
- Post-tension slab strikes. Hillside builds across Old Agoura and Morrison Ranch often sit on post-tension slabs. Blind core-drilling for a wet wall can cut a tensioned cable and trigger a structural repair that costs thousands and stops the job cold. We locate every cable before the drill starts.
- Fire Hazard Severity Zone surprises. Lots backing into the Santa Monica Mountains are often inside the Very High FHSZ boundary. That changes the exterior wall assembly, the eave details, and the venting spec. A bid that ignores it is a bid that changes the week work starts.
- Change-of-occupancy permit misfiling. Treating a garage ADU as a remodel instead of a change of occupancy sends the plan to the wrong review path and bounces back at the counter. The City of Agoura Hills sees an ADU permit differently than a garage finish-out, and the fire authority signs off on one but not the other.
- Undersized electrical service. Older Agoura Hills tract homes from the 1960s and 1970s often have 100-amp panels. A garage ADU with a kitchen, bath, and HVAC can push that past capacity, and the fix is a service upgrade before drywall goes up. We check the panel on the first walkthrough.
Pricing for Garage Conversion Contractor in Agoura Hills, CA
Here’s what we tell Agoura Hills homeowners on the first call. A simple garage-to-bedroom conversion runs $65,000 to $95,000. A garage-to-living-space with no kitchen lands $75,000 to $110,000. A full attached garage ADU runs $105,000 to $185,000, and a detached garage apartment conversion runs $110,000 to $175,000. Permit fees sit on top of those numbers, and the City of Agoura Hills permit schedule changes by valuation, so we give you a written line-item estimate that separates construction cost from city fees.
What moves the price in Agoura Hills is fire-zone review, slab conditions, electrical service capacity, and whether the existing garage walls and roof can be reused or need to come down. None of that should be a surprise after your first walkthrough. Call (361) 315-4177 and we’ll put the number in writing before you decide anything.

FAQs About Garage Conversion Contractor in Agoura Hills
Yes. If your lot backs into a Very High Fire Hazard Severity Zone, the City of Agoura Hills will require ignition-resistant exterior materials, specific eave and vent detailing, and possibly tempered glass on the fire-facing side. That typically adds $8,000 to $18,000 to a garage conversion in Agoura Hills. Call (361) 315-4177 and we’ll check your lot’s designation on the first call.
Sometimes. If the bathroom and kitchen can be positioned along an exterior wall where plumbing can stub out above grade or through a non-tensioned portion of the slab, we can keep core-drilling minimal. But most Agoura Hills hillside slabs require at least some strategic drilling, and we map every tensioned cable before the saw goes down. A free site visit tells you whether your slab allows a low-touch conversion.
A garage conversion ADU in Agoura Hills requires building, electrical, plumbing, and mechanical permits, plus a fire authority review when the lot sits in the Very High Fire Hazard Severity Zone. The application goes through the City of Agoura Hills as a change of occupancy, not a remodel. We pull every permit, coordinate the inspections, and you get a final sign-off before we hand you the keys.
Most garage conversion ADUs in Agoura Hills take 10 to 16 weeks from permit submittal to final inspection. Fire authority review can add two to three weeks on hazard-zone lots, and post-tension slab mapping adds a few days before plumbing rough-in. We put the calendar in writing with the price, so you know the schedule on day one. Call (361) 315-4177 for an exact timeline on your property.
Three things: fire-zone requirements your original contractor missed, post-tension cable strikes from blind drilling, and electrical service capacity that can’t carry the new unit. We price all three into the written estimate before work starts, and the Garrison Standard means the number you approve is the number on the final invoice. If something unforeseen comes up, it goes in writing before it goes into the wall.
