Fast, Reliable Garage Conversion ADU Across Clovis
Garage conversion ADUs in Clovis, CA typically run $140,000-$210,000 all-in, drawings through final inspection, depending on whether you’re converting an attached two-car garage in a 1990s tract home or a detached three-car bay in a Harlan Ranch property. The biggest variable isn’t square footage. It’s whether your HOA requires a ghost garage door and how much electrical panel work the existing structure needs. We’ve designed, permitted, and built garage conversions across Clovis since 2015, and we’ll give you a written price before any work starts. Call (971) 497-2402 to schedule a free estimate.
Why Ellery ADU Studio Is Clovis’s Preferred Garage Conversion ADU Company
Nadia Ellery founded this design-build studio in 2015, the year California’s ADU permitting landscape shifted, and she built it around one principle: the drawings, the permit set, and the construction are a single contract at a single written price. That matters in Clovis more than most cities. When the HOA’s architectural committee in Loma Vista rejects a window placement and your designer works for one firm and your builder for another, you get a blame loop. We eliminate that. One contract, one team, one price. The license number appears on every page, and the crew that shows up is background-checked and uniformed.
We’ve completed over 900 ADUs since 2015, many of them garage conversions in Clovis. Every project comes with a documented photo record on every visit, so you see what we found under the slab and what we did about it. Under Haven Standard Clause 1, the written price comes before any work begins. Under Clause 5, the scope is locked at signing. No door-side upsells, no scope creep. A live person answers calls 24/7 at (971) 497-2402.
We also offer a Free Second Opinion on any written estimate you already have in hand. If another builder quoted you a number without walking the slab or reading your HOA’s CC&Rs, bring it to us. We’ll tell you what they missed.
Our Garage Conversion ADU Services in Clovis
Our Garage Conversion ADU team handles the full scope, from first site walk through final inspection. Here’s what we do most often in Clovis.
Attached Garage Conversion
The dominant Clovis housing type is the 1990s-2010s two-story stucco tract home with a three-car garage. Attached conversions here are efficient because the structure already shares a wall with the house, and you’re not pouring a new foundation. But the HOA piece is the real work. In north Clovis, most of these projects need a ghost garage door - a non-functional garage door mounted over the converted opening to satisfy the architectural committee. We handle that coordination directly.
Carport Conversion
Less common in Clovis’s newer subdivisions, but older ranch-style homes near Old Town Clovis sometimes have carports that were never enclosed. Converting a carport means new walls, insulation, and often a full electrical run from the main panel. Those 1950s-1970s homes typically need a panel upgrade to support a second dwelling, and we’ll flag that in the written scope before you commit.
Garage Partition & Bathroom Add
Some Clovis homeowners only want part of the garage converted - a studio or a bedroom with a bath - while keeping one bay for storage or a workshop. The partition wall has to be engineered for seismic shear, and the bathroom drain line often ties into the main sewer at the garage slab edge, which is a straightforward but specific detail. We’ll spec hot-dip galvanized anchors and stainless wedge anchors so the new wall doesn’t move when the slab shifts through valley temperature swings.
Garage JADU
A Junior ADU within an existing garage footprint is the low-cost path many Clovis homeowners take when they want a rental unit but don’t want a full second kitchen. JADUs cap at 500 square feet and can share the main house’s sewer or water line. In an HOA-governed community, a JADU often still triggers architectural review, but the ghost garage requirement is less common since the garage door stays functional. We’ll tell you which path applies to your specific lot.

Trusted Brands We Service in Clovis
We specify and coordinate prefab and modular systems from Abodu, Cover, and Dvele within the same single contract. If your Clovis lot is tight or your HOA wants a faster build with less on-site disruption, a panelized or modular garage conversion can cut weeks off the schedule. We don’t push these systems on every project. We name them when they fit, and we coordinate the delivery, set, and finish work so you’re not managing three separate vendors. The written price covers whatever system we spec.
Common Garage Conversion ADU Problems We See in Clovis Homes
- Spalled slabs at saw-cut joints. In a Harlan Ranch three-car garage, our crew found the original stamped-concrete slab had spalled at every joint because the builder used unsealed joints and plain steel dowels. After ten valley summers of 110°F expansion and winter contraction, the edges crumbled and the slab telegraphs cracks through the new LVP. We specified hot-dip galvanized anchor bolts, stainless-steel wedge anchors for the new partition wall, and full-depth polyurea joint sealant before the ADU went in.
- Undersized mini-splits that ice over. A garage conversion with a standard inland-spec mini-split run at 105°F+ fails to hold 78°F because the builder sized for 400 sq ft but ignored the uninsulated slab edge and west-facing garage door. The compressor short-cycles and the indoor coil ices over within two summers. In Clovis, standalone ADU HVAC sizing is a design decision, not an afterthought.
- Rust streaks from electro-galvanized fasteners. Using electro-galvanized roofing screws on the new shed roof leads to rust streaks down the stucco within three years, driven by valley fog and irrigation overspray. We see this on older Loma Vista conversions where the original garage had no roof penetrations. We spec hot-dip galvanized or stainless fasteners on every exterior surface.
- Ghost garage doors with seized rollers. An HOA-required ghost garage door installed with standard steel track rusts at the bottom roller and binds after two winters of Clovis’s alkaline dust. The door then fails the architectural committee’s re-inspection and costs $800 to re-hang on stainless rollers. We mount ghost doors with marine-grade hinges and stainless track from day one.

FAQs - Garage Conversion ADU in Clovis
A ghost garage door is a non-functional garage door mounted over a converted garage opening to satisfy an HOA’s architectural requirement that the façade still read as a garage. You need one in north Clovis because HOA-governed communities like Harlan Ranch and Loma Vista have CC&Rs written before California’s ADU reform laws, and those CC&Rs require a garage-door-style façade even after the garage becomes living space. State law voids the parking mandate, but the HOA’s architectural committee still controls exterior appearance. Call (971) 497-2402 to find out if your specific HOA requires one.
Yes. California law bars HOAs from outright prohibiting ADUs, but it does not stop architectural review, and in Clovis that review often means a ghost garage door. We handle the HOA paperwork and the design so the door satisfies the committee while the interior meets city code. The door we mount uses stainless rollers and marine-grade hinges so it doesn’t seize in Clovis’s alkaline dust. Call (971) 497-2402 and we’ll review your CC&Rs.
Clovis sits in the San Joaquin Valley and routinely sees summer highs of 105-112°F, and a converted garage lacks the thermal mass of an attached home. The slab edge is uninsulated, the west-facing wall absorbs direct afternoon heat, and the original garage door opening creates a thermal bridge. An undersized mini-split short-cycles, ices over, and fails within two summers. We size the HVAC for the actual structure, not the square footage alone. Call (971) 497-2402 for a load calc on your specific garage.
Usually yes. Saw-cut joints are control joints, and when the original builder used plain steel dowels and left the joints unsealed, the edges spall after years of valley temperature swings. We specified hot-dip galvanized anchors, stainless wedge anchors, and full-depth polyurea joint sealant in a Harlan Ranch conversion where the slab had crumbled at every joint, and the ADU went in without issue. The written scope will include whatever slab remediation your specific garage needs. Call (971) 497-2402 for a slab inspection.
A Clovis HOA-compliant conversion typically runs $15,000-$25,000 more than the same job in a non-HOA Clovis neighborhood. That gap covers the ghost garage door and stainless hardware, architectural review fees, and additional exterior design work to match the HOA’s palette. On a $160,000 conversion, the HOA piece is about 10-15% of the total. The written price accounts for it before work starts. Call (971) 497-2402 for an exact quote - estimates are free.
