Fast, Reliable Garage Conversion ADU Across Lemoore
Garage conversion ADUs in Lemoore typically run $145,000-$210,000 all-in, from the first plan set through final Kings County inspection. That figure assumes a standard attached two-car garage on a 1960s-1980s slab-on-grade ranch, which describes most homes here. The number moves based on what’s inside your walls: electrical panel condition, slab flatness, and the moisture damage that tule fog leaves behind. Call (971) 497-2402 and we’ll walk the garage with you, then put the price in writing before any work starts.

We know Lemoore’s housing stock. Not in a brochure sense. We know that most garages here were framed during successive NAS Lemoore expansion phases, which means aluminum branch wiring, unsealed stem walls, and slabs that have moved on Kings County’s expansive clay. That’s not a problem to be discovered on day 14 of your build. It’s a line item we expect and price before the first permit drawing leaves our desk. Our Garage Conversion ADU team works from the Fresno, Central Valley office, and we schedule crews in Lemoore every week.
Why Ellery ADU Studio Is Lemoore’s Preferred Garage Conversion ADU Company
Since 2015, we’ve designed, permitted, and built more than 900 ADUs across the Central Valley. Every single one started with a written price before work began, under Haven Standard Clause 1. That matters in Lemoore because Kings County’s building department runs a small operation, and the post-AB 68 surge in ADU applications has stretched permit-review timelines longer than in Fresno or Tulare County. Out-of-county contractors who don’t front-load plan sets with state-mandated ADU exemption language and utility letters stall out. We don’t, because we know the office’s review rhythm and we submit accordingly.
Our Lemoore clients don’t get a sales pitch about how many years we’ve been in business. They get a permit set that passes Kings County review without three rounds of corrections, a documented photo record on every visit showing what was found and what was done, and a 365-Day Done Right Promise in writing: if the finished ADU isn’t built to the permitted drawings, we make it right. Nadia Ellery set that standard when she founded the studio, and it governs every contract we sign.
The old-model problem with ADUs isn’t design skill. It’s the gap between the designer’s drawings and the builder’s execution, the two of them pointing at each other when the inspector flags something. We closed that gap by making Ellery ADU Studio a single-contract design-build firm. Drawings, permit set, construction: one contract, one price, one name on the punch list. Homeowners in Lemoore who’ve heard horror stories from friends in Hanford or Visalia tend to appreciate that arrangement.
Our Garage Conversion ADU Services in Lemoore

Attached Garage Conversion
The most common conversion in Lemoore, because the bulk of the city’s residential stock is single-story ranch homes with attached two-car garages built between 1965 and 1985. These garages share a wall with the main house, which cuts foundation costs, but it also means your electrical panel, your roofline, and your existing HVAC all become part of the project. We inspect all three before we price, and anything we find goes into a written allowance so you approve it before we touch it.

Detached Garage Conversion
Detached garages in Lemoore, especially on older lots off Hanford Armona Road and up toward the west side, tend to be smaller and rougher. Many were built as afterthoughts with minimal footings and no vapor barrier. Converting one into a compliant ADU usually means grinding the slab, adding a capillary break, and running new underground utilities from the main house. The good news: Kings County’s post-2020 ADU streamlining laws generally treat a conversion of an existing structure more leniently than new construction, so setbacks rarely block the project.

Garage Partition & Bathroom Add
Some Lemoore homeowners don’t want to lose the whole garage. They want a studio unit in the back half and storage or a workshop up front. A partition wall with proper fire separation, a new bathroom, and a separate exterior entry turns part of the garage into a rentable space without surrendering the entire footprint. We run these as full ADU permits, not unpermitted “bonus rooms,” because anything short of that creates problems when you sell or refinance the property.

Garage JADU
A Junior ADU carved out of an existing attached garage is the least expensive path to a legal rental unit in Lemoore, often running $80,000-$120,000 when the garage already has a bathroom or one can be added against an existing wet wall. JADUs cap at 500 square feet and don’t require their own parking space, which matters on Lemoore’s modest lots. The catch is that JADUs must be attached to the main house and share systems, so they work best when your main panel has capacity to spare.

Trusted Brands We Service in Lemoore
We specify and coordinate prefab and modular systems from Abodu, Cover, and Dvele within the same single contract that covers our site-built conversions. That means a Lemoore homeowner weighing a detached prefab unit against a garage conversion gets one written price for either path, with James Hardie siding and trim specified where the design calls for it. We stock common conversion materials locally in the Central Valley and order prefab panels with Lemoore’s climate in mind: the 105-110°F summer heat and the dense tule fog from November through February both shape what we put on the exterior and inside the walls.
Common Garage Conversion ADU Problems We See in Lemoore Homes

- Undersized electrical panels. A 100-amp Zinsco or Federal Pacific panel in a 1960s-1980s Lemoore ranch can’t pass a garage-to-ADU permit inspection once walls are open. The upgrade becomes unplanned work mid-project unless someone planned for it. We plan for it.
- Tule fog moisture damage. Dense fog from November through February creates extended high-ambient moisture. Unsealed stem walls and slab edges wick that moisture into sill plates and framing, so what looks like a solid garage stud often crumbles when you strip the drywall. A capillary break and vapor barrier under new flooring aren’t optional here.
- Slab heave on expansive clay. Kings County’s clay soils move. Garage slabs that looked flat at the home inspection are often out ¾-1¼ inches by the time we run a level across them. Grinding or a self-leveling underlayment becomes a line item, and it’s better priced up front than discovered after tile goes down.
- Kings County permit review delays. The small rural building department can take weeks on plan reviews. Homeowners who gut a garage before front-loading AB 68 exemption language and utility letters end up with a torn-apart garage and no permit. We submit the permit set before demo day, every time.

FAQs - Garage Conversion ADU in Lemoore

Plan review in Kings County currently runs four to eight weeks for a garage conversion ADU, depending on workload. That’s longer than Fresno or Tulare County, and the main cause of extension is incomplete submittals. We shorten the timeline by front-loading every plan set with the AB 68 exemption language, utility letters, and structural calculations the reviewers flag most often, so your project doesn’t sit in a correction loop. Call (971) 497-2402 and we’ll tell you what current wait times look like before you commit.
Most 1960s-1980s Lemoore ranches have 100-amp panels, and many are Zinsco or Federal Pacific brands that inspectors won’t pass once walls are open for a garage-to-ADU conversion. You will very likely need a panel upgrade to 200 amps, which runs $3,500-$6,500 as part of the conversion scope. We inspect the panel during our first walk-through and price it into the written quote, so you know before signing.
Lemoore routinely hits 105-110°F for weeks in summer, and an undersized mini-split fails quickly in that heat. We size every ADU’s cooling system for the unit’s square footage, insulation level, and orientation, not for a generic California climate. That means a one-bedroom garage conversion here usually needs a 12,000-18,000 BTU high-efficiency mini-split rather than the 9,000 BTU unit people sometimes get quoted elsewhere.
Because the tule fog season from November through February pushes moisture into unsealed slab edges and stem walls, and a contractor who skips the capillary break and vapor barrier won’t see the failure until the first spring after move-in. We open up the walls, inspect the sill plates, and write the waterproofing scope into the contract before drywall comes down. The Kings County inspector sees the vapor barrier before we re-close the walls, and our photo record documents every step.
Yes. A JADU under 500 square feet carved from an existing attached garage is legal in Lemoore under state law, and it skips the parking-space requirement that full ADUs sometimes trigger. The trade-off is that a JADU must share systems with the main house and is typically rent-restricted compared to a full ADU. For a military rental play near NAS Lemoore, a full ADU usually commands higher rent, but a JADU gets you a legal unit for less money up front. Call (971) 497-2402 and we’ll run both scenarios for your specific garage.
What Opening Up a Lemoore Garage Actually Turns Up
Here’s what nobody tells you about converting a 1970s Lemoore garage into an ADU: the walls hide things. On a slab-on-grade ranch near the west side, our crew opened an attached two-car garage and found aluminum branch wiring from the original NAS expansion build, a sill plate rotted from years of tule fog moisture wicking through unsealed stem walls, and a garage slab that had heaved 1¼ inches from expansive clay. We wrote the panel upgrade, rewire, sill replacement, and slab grinding into a written allowance before drywall came down, then got the Kings County inspector to sign off on the vapor barrier and mini-split sizing before we re-closed the walls. The surprise total was approved, not argued, on move-in day.
That’s the core of how we work in Lemoore. Because Lemoore sits 12 miles from NAS Lemoore with a military tenant pool rotating on 2-3 year PCS cycles, garage conversion ADUs here are underwritten by Kings County BAH rates that make rental income projections far more concrete than in Hanford or Visalia. That same tenant pipeline means vacancy risk is predictable, not speculative, if the unit is code-compliant and weather-tight. The property owner near the base who converts a garage into a one-bedroom ADU isn’t guessing what it will rent for. They know the BAH rate.
Our job is to make sure the unit we hand you passes inspection, holds up to Lemoore’s heat and fog, and rents at the number you budgeted. The way we do that is the least exciting part of the whole project, and the most important: we inspect before we price, we document every visit with photos, and we put the written price on paper before the walls come down.
