Homedale's ADU builder for farm and family land
A small Owyhee County ag town on the Snake River. Most Homedale lots have the acreage that Boise homeowners only dream about — which makes a backyard ADU one of the most practical housing moves out here.

Why Homedale homeowners are building backyard homes
Homedale is a small farming town — roughly 3,200 people, the largest city in Owyhee County, sitting right on the Snake River where it forms the line with Canyon County. We are not going to pretend it is a hot urban rental market. What Homedale has instead is land. Lots here run bigger than almost anything in Ada County, a lot of households sit on a parcel with real acreage, and that changes the entire ADU conversation. Out here an accessory dwelling is less about squeezing a rental into a tight backyard and more about housing the people already on your land — a parent, an adult kid starting out, a seasonal farm hand, or a caretaker.
The economics work differently than they do in Boise too. Land you already own carries no extra cost basis, so when you build an ADU on a Homedale acreage lot, nearly every dollar goes into the structure rather than into buying or carving out a buildable footprint. Flat, open ag ground also skips the foothill problems — no hillside grading, no engineered retaining walls, no access headaches. For a family that wants to keep three generations on the same property, or a grower who needs decent housing for help during harvest, that is a far cheaper path than a second house or a new mortgage.
Homedale also sits in the heart of Idaho's Sunnyslope wine country, with the Snake River Valley AVA, orchards, and a growing agritourism scene right up the road toward Caldwell. That backdrop opens a second use case: a clean, permitted detached unit on a rural property can serve as a long-term rental, a farm-stay, or guest quarters. Demand is thinner than in Nampa or Caldwell, so we are honest about that in planning — but the low build basis means the numbers can still pencil, especially when the unit doubles as family housing first and income later.

Neighborhoods
Where we build in Homedale
We've worked across most of Homedale — here are the neighborhoods most homeowners are asking us about.
In-town residential streets
The blocks just off the core inside city limits. Standard single-family lots, some with alley access — a good fit for a detached studio behind an existing home.
Sunnyslope / Wilson-area rural
Acreage and farm parcels on the Sunnyslope side toward the wine trail. Plenty of room for a detached unit; we work the Owyhee County and area-of-impact rules rather than city zoning.
Snake River edge lots
Parcels along the river on the east side of town. Watch floodplain mapping and setbacks here — we pull the panel before we site anything near the bank.
Ag parcels north of town
Working farm ground toward Wilder and the Canyon County line. Big footprints make multigenerational and seasonal-worker housing the natural ADU use case.
Rural-residential fringe (county)
Larger lots outside city limits under Owyhee County jurisdiction. Different review path than in-city builds — septic and well capacity usually drive the plan more than zoning does.
Zoning + Permits
Homedale's ADU rules in plain English
Homedale ADU rules depend on whether your lot is inside city limits or in unincorporated Owyhee County — and the answer changes the whole permit path. Idaho's 2026 ADU law (SB 1354) only forces ADU allowances and removes owner-occupancy for cities over 10,000 people, so it does not compel Homedale (about 3,200) or the county. That means local ordinance governs here, and the single most important step is confirming your jurisdiction and pulling the current rules before you design anything.
City vs. county is the first question
In-city Homedale lots follow the city's code through the Homedale building department; lots in the surrounding area-of-impact or unincorporated Owyhee County follow the county's Title 9 zoning. We confirm which set applies to your parcel before drawing a thing.
SB 1354 does not mandate ADUs in Homedale
Idaho's 2026 ADU law (effective July 1, 2026) requires cities over 10,000 to allow an ADU per single-family lot and bans owner-occupancy rules for them. Homedale is well under that threshold, so the state mandate does not apply — local ordinance still controls.
Septic and well drive most county lots
On unincorporated acreage, the binding constraint is usually Southwest District Health septic capacity and your well, not a setback line. We size the ADU to what your system can carry, or budget the upgrade up front so it does not stall the permit.
Floodplain matters near the Snake River
Homedale sits on the river, and some east-side and Sunnyslope-area parcels touch mapped floodplain. We pull the FEMA panel for your lot early — building in or near a flood zone changes foundation, elevation, and permitting requirements.
Confirm setbacks and size with the jurisdiction
Setbacks, lot-coverage caps, and any ADU size limit vary by district and by whether you are in city or county. We verify the current numbers with the right office for your parcel rather than assume a figure — and put what we confirm in writing.
Why Homedale
What makes Homedale a strong ADU market
Acreage lots most cities can't offer
Homedale parcels run far larger than Boise or Meridian backyards. There is room for a real detached ADU, a driveway, and the building you already use — without crowding anything or fighting a tight envelope.
Built for multigenerational land
The most common Homedale ADU is family housing — a parent, an adult child, or a caretaker staying on the same property. Our one-bedroom Kingfisher and two-bedroom Kestrel are sized exactly for keeping a household together on one lot.
Farm and seasonal-worker housing
For growers, a permitted detached unit is decent year-round or harvest-season housing for help, instead of a trailer or a long commute. Built to code from day one, it doubles as a rental or guest unit in the off-season.
Low cost basis on land you own
Build on acreage you already own and there is no land to buy and no lot to carve out. Flat ag ground skips foothill grading and retaining walls, so nearly every dollar goes into the structure — a cheaper path than a second house.
Recommended Plans
Best pre-approved plans for Homedale lots
The City of Boise's pre-approved plans work in every Treasure Valley jurisdiction. Here are the picks that fit this city's lots and rental market best.
Type CThe Kingfisher
From $170k
491 sq ft · 1 · 1 ba
The 491 sq ft Kingfisher is the workhorse for Homedale acreage. A walled-off bedroom, full kitchen, and real living room give a parent, adult child, or year-round farm hand genuine privacy — and the generous lots out here mean siting it is rarely the constraint.
See the The Kingfisher
Type DThe Kestrel
From $245k
695 sq ft · 2 bd · 1 ba
On larger Homedale parcels where one bedroom isn't enough — a young family member with a kid, or two people sharing — the 695 sq ft two-bedroom Kestrel fits without crowding anything. Big lots are exactly what this plan wants.
See the The Kestrel
Type G-1The Sandpiper
From $145k
396 sq ft · Studio · 1 ba
If you want covered storage or shop space alongside the dwelling, the Sandpiper pairs a 396 sq ft studio with a single-car garage on one foundation. Practical on a rural lot where a sheltered bay earns its keep year-round.

What ADU homeowners in Homedale actually check
Local specifics — not generic Treasure Valley copy.
What to check first on a Homedale lot
First, confirm whether your lot is inside Homedale city limits or in unincorporated Owyhee County — the rules and the permitting office are different. Then check septic and well capacity (the real constraint on most rural lots) and pull the FEMA flood panel if you're anywhere near the Snake River. Parcel records are with the Owyhee County Assessor.
Common Homedale lot types
Homedale lots split into two worlds. In-town parcels on the original grid are standard single-family lots, some alley-loaded. Outside the core — Sunnyslope, north toward Wilder, the county fringe — you get acreage and working farm ground with room to spare. Buildable envelope is rarely the issue out there; septic, well, and floodplain are.
Detached vs garage conversion in Homedale
Detached wins almost everywhere in Homedale — lots are large and the use case is usually housing a family member or worker who needs their own door, not converting an attached garage. The Kingfisher and Kestrel are the typical picks; the Sandpiper makes sense when a sheltered garage bay is genuinely useful on a rural property.
Cost considerations in Homedale
Labor and materials track at or slightly below the Boise baseline. The Homedale-specific swings are septic and well: an acreage lot whose system can't carry a second dwelling needs an upgrade, which is the most common cost surprise out here. Flat ag ground, by contrast, saves real money versus a foothill site — no grading, no retaining walls.
"We farm out past the edge of town and my father-in-law could not keep living alone anymore. Buying him a second house was never going to happen out here. Boise ADU put up a Kingfisher on our place — his own kitchen, his own door, fifty feet from ours. They sorted out the septic question early so the permit never stalled."

FAQ
Homedale ADU questions, answered
Can I build an ADU on my Homedale property?
Most likely yes, but the path depends on whether your lot is inside city limits or in unincorporated Owyhee County. We start by confirming your jurisdiction, then pull the current ADU rules from the right office — the city building department for in-town lots, the county for acreage — before any design work begins.
Does Idaho's new 2026 ADU law apply to Homedale?
Not the mandate part. SB 1354 (effective July 1, 2026) requires cities over 10,000 people to allow an ADU per single-family lot and removes owner-occupancy rules for them. Homedale is around 3,200 residents, so the state requirement does not force the city's hand — local ordinance still governs. We verify what your specific parcel allows.
I'm on acreage outside the city. What's different?
On unincorporated county land, septic capacity and your well usually matter more than zoning setbacks. Southwest District Health reviews the septic; if your system can't carry an added dwelling, we budget the upgrade up front so it doesn't stall the build. The county's Title 9 zoning, not the city code, sets the land-use rules.
Does being near the Snake River cause problems?
Sometimes. Homedale sits on the river, and some east-side and Sunnyslope-area parcels touch mapped floodplain, which changes foundation height and permitting. We pull the FEMA flood panel for your exact lot early so there are no surprises — most properties are clear, but it's worth confirming before you design.
Can I house seasonal farm workers in an ADU?
A permitted ADU is a legitimate, code-built option for year-round or harvest-season housing on your property — far better than a trailer or a long commute for help. Because we build it to full rental standard (real kitchen, code egress), the same unit can serve as a rental or guest quarters in the off-season.
Is it worth building an ADU here for rental income?
Be realistic: Homedale's rental demand is thinner than Nampa's or Caldwell's, so we don't oversell yield. What makes the numbers work is the low cost basis — building on land you already own, on flat ground, with no lot to buy. When the unit houses family first and rents later, the math often pencils where a pure rental play wouldn't.
