Fast, Reliable New Detached ADU Across Lemoore
A new detached ADU in Lemoore typically runs $285,000 to $340,000 all-in, from permit drawings through final inspection, for a 750 to 900 square foot one-bedroom or two-bedroom unit built on a slab-on-grade lot. That price assumes marine-grade exterior hardware and a properly sized mini-split for San Joaquin Valley summers, which we’ll get to. The good news: Lemoore’s rental math is the strongest in Kings County because NAS Lemoore keeps a steady pipeline of military families on two- to three-year rotations. Call (971) 497-2402 and we’ll walk you through what your specific lot can support, in writing, before you commit to anything.
We’re Ellery ADU Studio, a design-build practice that has designed, permitted, and built more than 900 ADUs since 2015. We serve Lemoore homes throughout the city, from the older ranch subdivisions near Cinnamon Drive down to the newer lots west of Highway 41. If you’re weighing a detached ADU as a long-term rental asset or a place for aging parents, you want a studio that already knows what Lemoore’s fog, clay soil, and Kings County permitting office will ask for.
Why Ellery ADU Studio Is Lemoore’s Preferred New Detached ADU Company
What we bring to a Lemoore ADU project is documentation, not vague promises. Every homeowner we work with receives a written price before any work starts, under Haven Standard Clause 1. That’s not a marketing line. It’s the contract you sign. If the scope changes later, that’s a conversation about a written change order, not a door-side upsell. We also hand you a documented photo record on every visit, so you can see what the crew saw, not just read a summary of how it went.
Lemoore presents a specific set of conditions that out-of-area contractors routinely underestimate. The tule fog that settles over the valley from November through February isn’t just a visibility problem for the drive to the lumberyard. It carries saline moisture that attacks standard fasteners, window frames, and paver joints. Our crews have built enough detached ADUs in Lemoore to know which materials survive here and which ones start failing before the first tenant finishes unpacking. We also know Kings County’s building department rhythm, which we’ll explain below.
Nadia Ellery, our founder, runs the studio with a bias toward evidence. If a foundation line item will cost more because your lot sits on expansive clay, you’ll hear that with a soil report in hand, not as a guess. Lemoore homeowners tell us that straightforwardness is the main reason they call us back and refer neighbors.
Our New Detached ADU Services in Lemoore
Custom Built ADU
A custom-built detached ADU in Lemoore gives you full control over the floor plan, roofline, and finish package. Most of the lots we see are single-story ranch homes on slab foundations from the 1960s through 1980s, which means we’re typically designing a unit that respects the original house’s scale while adding a separate, fully independent dwelling. We handle the full permit set, including all state-mandated ADU exemption language for setbacks and utility letters, because Kings County’s building department reviews faster when the plan leaves nothing to interpret.
Prefab ADU Installation
Prefab ADUs from Abodu, Cover, and Dvele can cut months off a Lemoore timeline, but the installation is not a simple drop-and-bolt job here. The slab and foundation still have to be engineered for expansive clay, and the mechanical connections have to be right for 105°F summers. We specify and coordinate the prefab system within our single design-build contract, so you get one written price for the factory unit, the site work, the utility hookups, and the finish.
Modular ADU
Modular ADUs sit between prefab and fully custom. The modules are built off-site to plan, then trucked to your Lemoore property and set on a foundation we’ve already poured and waterproofed. Modular construction works well on the modest lot sizes common across Lemoore, especially when the access path from the street to the back yard is tight. We route utilities before the modules arrive so the set day is mostly connecting, not digging.
Studio ADU
A 400 to 550 square foot studio ADU is the most common request we get in Lemoore, and it’s often the smartest first move. It keeps the total project cost lower while still producing a rentable unit for the NAS Lemoore tenant pool. The catch is that a studio still needs a correctly sized mini-split, a vapor barrier spec’d for fog-season moisture, and exterior hardware that won’t pit within a year. We build studios with the same coastal-grade shell as our larger units.
1-Bed & 2-Bed ADU
One-bedroom and two-bedroom detached ADUs in Lemoore rent more reliably to military families than to single service members, and the Kings County BAH rates support the math. A two-bedroom unit on a lot off Cinnamon Drive or near the Lemoore Golf Course will command meaningfully higher rent than a studio, though the construction cost rises with square footage and bathroom count. We’ll give you the rent range and the build range together so you can see whether the extra bedroom pencil outs.

Trusted Brands We Service in Lemoore
We specify James Hardie siding on most Lemoore ADU shells because it handles the fog-season moisture cycle better than cheap composite lap. For prefab and modular work, we coordinate Abodu, Cover, and Dvele systems regularly and know their panel connection details well enough to catch factory oversights before they become site problems. We don’t stock parts for every brand, but we pre-order the exact fastener and flashing kits each system requires for Lemoore’s salty fog belt.
Common New Detached ADU Problems We See in Lemoore Homes
- Powder-coated steel posts rusting at the base. Where the post meets the concrete, fog-season moisture wicks into the unsealed joint and rust blooms within three winters. We seal every post-to-concrete connection with a marine-grade sealant and use hot-dip galvanized bases even under powder coat.
- Standard aluminum window frames pitting on north-facing walls. Salty morning dew from tule fog settles on mill-finish frames and starts electrolytic pitting, which lets water into the rough opening. We specify marine-grade anodized aluminum on all exterior windows.
- Paver joints washing out under wet-dry cycles. Fog saturates the joints, then 110°F days bake them, and plain sand erodes or compacts unevenly. We fill patio and walkway joints with polymer sand and slope the base so water moves away from the ADU entrance.
- Undersized HVAC units failing by August. A small ADU still needs a heat load calculation for Lemoore’s sustained 105°F weeks. A one-ton mini-split in a 500 square foot studio will not keep up. We size every unit with a Manual J and show you the report.

FAQs - New Detached ADU in Lemoore
We use hot-dip galvanized or stainless fasteners on every exterior connection, because standard zinc-plated hardware corrodes within two or three fog seasons. The added cost is roughly $800 to $1,400 on a typical shell, and it prevents the rusted screw heads and loose siding nails we see on Lemoore ADUs built to inland spec. Call (971) 497-2402 and we’ll include the fastener line item in your written quote.
Marine-grade anodized aluminum frames resist the electrolytic pitting that salty tule-fog dew causes on standard mill-finish aluminum and on many vinyl frames, especially on north-facing walls. We’ve replaced pitted frames on Lemoore builds before the siding went up. A full window package upgrade runs $3,000 to $6,000 on a typical ADU and buys you decades of dry rough openings.
They wash out and erode under the repeated wet-dry cycle of winter fog and 110°F summer heat, creating uneven steps and a tripping hazard at the ADU entrance within about two years. We fill joints with polymer sand and slope the base away from the door, which adds roughly $1,200 to $2,000 to a typical patio. Call (971) 497-2402 and we’ll show you the joint spec in your quote.
Yes, because the failure cost lands fast. A pitted window frame that lets water into the rough opening can require siding removal and reframing at $4,000 to $9,000, and a wobbling railing post on a tenant-occupied ADU is a liability. The 8 to 10 percent shell premium on coastal-grade materials is cheaper than one remediation cycle, which is why we write it into every Lemoore quote as standard, not as an upgrade.
Military tenants rotate every two to three years, which means high tenant turnover, which means your exterior materials need to survive not only the fog but also periodic vacancy and deferred maintenance between leases. Marine-grade hardware, low-maintenance James Hardie siding, and sealed joints all reduce the repair burden between PCS cycles. We’ll spec those materials as default on your Lemoore ADU and explain the line-item cost in person. Call (971) 497-2402 and ask for a written quote; we’ll walk the lot with you and show you exactly what makes sense for your property.
