A garage conversion in West Hills typically runs $85,000 to $165,000 for a full ADU with kitchen and bath, and $55,000 to $95,000 for a bedroom conversion without plumbing. That range covers the structural work, insulation, drywall, electrical, and finishes. What moves the number is what we find when we open the walls.
We work throughout West Hills, from the streets off Vanowen and Platt to the hillside lots above Bell Canyon Road and the neighborhoods around Capistrano Avenue. Our crews know the difference between a 1958 tract garage and a newer one off Roscoe Boulevard, and that knowledge changes how we price the job before we start. Call (361) 315-4177 for a written estimate.

Garage to Bedroom Conversion in West Hills
A garage to bedroom conversion in West Hills turns an attached or detached garage into a finished sleeping room. The first sentence tells you the scope: re-frame the walls, insulate, run electrical, add egress windows, finish with drywall and flooring, and tie into the existing HVAC where code allows. The cost for a garage to bedroom conversion in West Hills typically runs $55,000 to $95,000, before permit fees.
What the Job Actually Involves
We start with the slab and the framing. Most West Hills garages were built in the 1950s through 1970s tract boom, and many of those slabs are three inches thick with no footing. That does not pass current structural code for living space. We lift the garage, pour a proper foundation, and address the header before we spend a dollar on drywall.
When a Bedroom Makes Sense
A bedroom conversion works when the goal is more sleeping space for family, a quiet room for an aging parent, or a home office with a door that closes. It is a smaller project than a full ADU, and it moves faster: six to ten weeks once permits are in hand. Some West Hills homeowners start with a bedroom and add plumbing later, which is fine, as long as the framing we put in today is sized for the future.
Garage Conversion ADU in West Hills
A garage conversion ADU in West Hills is a fully permitted dwelling unit with its own entrance, kitchen, bath, and utility connections. The cost in West Hills runs $85,000 to $165,000, depending on whether we are converting an attached garage or a detached one, and whether the existing utility lines can carry the added load. This is the project that lets you rent the unit out or house a relative with real privacy.
The Structural Reality in West Hills
We converted a detached two-car garage off Bell Canyon Road into a 420-square-foot ADU with a kitchenette and full bath. The existing slab and header were undersized, so we had to pour a new foundation and replace the header. That added cost and time that would not have applied to a newer garage. That is the honest structural reality in much of West Hills.
Permits and the Hillside Ordinance
Many West Hills properties sit in a hillside ordinance overlay district. That means the city reviews the project for slope stability, drainage, and geotechnical impact before we get a building permit. The review can add weeks. We check the overlay status on day one, because it changes the timeline and the budget, and we would rather you know both before we sign.
Trusted Brands We Service in West Hills
We work with the systems West Hills homeowners already research. Abodu, Cover, and Dvele are prefab and modular platforms we know well, and we pair them with conventional builds using James Hardie siding where the site or the budget calls for it. We can also repair or upgrade an existing garage structure we are converting, using the same materials list we would spec for a new build. Because we work with these platforms regularly, we can get West Hills projects scheduled and priced faster than a general contractor who is seeing the system for the first time.
Common Garage Conversion Contractor Problems We See in West Hills Homes
- Slabs that pass as parking surfaces but not as living floors. A 1962 garage slab was poured for a car, not a bedroom. We regularly find undersized footings and cracked slabs that must be replaced before walls go up. That changes the budget after demo, and it is the single biggest cost surprise in West Hills.
- Missing the hillside ordinance review. Properties above Bell Canyon Road and along the slopes near Roscoe Boulevard often need geotechnical or drainage review before permit approval. Skipping that step delays the project by weeks. We check it before we draw the first plan.
- Prior unpermitted work surfacing late. A title and permit history check shows us whether a previous owner added a wall, a window, or a subpanel without a permit. If we find it, we correct it before it becomes a correction notice in the middle of your build. That is cheaper than finding it at final inspection.
- Undersized headers on wide garage openings. The original double-wide header was sized for a garage door, not a solid wall with a window and a door. When we convert the opening, that header usually needs to be replaced. We price it in from the start on West Hills properties from the 1950s and 60s.

FAQs About Garage Conversion Contractor in West Hills
Plan for three to six months from submittal to permit issuance, and longer if your West Hills property is in a hillside ordinance overlay. The overlay triggers geotechnical and drainage review, which adds weeks. We submit complete plans the first time, which is the single best way to hold the timeline. Call (361) 315-4177 and we will check your address before you spend a dollar on plans.
Probably, if the garage was built in the 1950s, 60s, or 70s. Most slabs from that era are three inches thick with no footing, and they do not pass structural code for living space. We will inspect the slab, and if it needs replacement, we will put that number in writing before demo starts. You will not find out at the framing inspection.
Usually yes for a full ADU. The kitchen and bath need sewer, water, and electrical runs sized for the new load, and that means trenching from the main line. Some attached garages can tie into existing lines; most West Hills detached garages cannot. We map the utility path during the site visit and price it accordingly.
The three things that change price are: foundation replacement, header replacement, and unpermitted prior work we did not know about. We find all three before we start, not after, which is why our written price includes a structural inspection before the contract is signed. If a change is required by the inspector, we write the change order and get your approval before the work continues. Nothing moves without your signature. Call (361) 315-4177 for a written estimate built on the actual condition of your garage.
Yes, and it is a common choice when the goal is a guest room, office, or hobby space rather than a rentable unit. A detached garage to bedroom conversion in West Hills runs $55,000 to $95,000. The garage still needs a proper foundation and insulation, but you avoid the kitchen, bath, and utility upgrades a full ADU requires. We can also frame it so plumbing can be added later without tearing out walls. Call (361) 315-4177 and we will walk you through both paths.
