ADU options for Boise properties

Every lot is different, so we start with what yours can support. Some homeowners want a detached backyard cottage for privacy and rental potential; others want a suite attached to the main home or built above a garage. We walk your property, weigh the trade-offs, and recommend the option that fits your goals, your budget, and Boise's rules.

Mother-in-law suites and backyard cottages

Both are complete, independent living spaces with a kitchen, bathroom, and living area — the difference is whether they connect to your home or stand on their own. We build either as custom work, designed to look like it belongs with your house rather than an afterthought bolted onto the yard.

Boise zoning, permits, and site planning

ADUs live and die by the details of local code — lot coverage, setbacks, height limits, parking, and utility connections. We review your property against current Boise zoning before design, then handle the permits and inspections so the project is buildable and on the record from the start.

ADU budget and timeline factors

Size, site work, and how far utilities have to run are the biggest cost drivers, along with your finish choices. Design and permitting typically take a few months, and a detached build usually runs four to eight months. We give you an itemized estimate and a realistic schedule up front — no surprises.

Our ADU design and construction process

We start with your goals and a look at the property, then move to a design and a clear estimate. Once you approve, we handle permitting, site work, framing, the trades, and finish work through to the final walkthrough — with one point of contact the whole way, the same as any custom home we build.

Boise ADU builder FAQs

Does my Boise property qualify for an ADU?

Most single-family lots can support one, but lot size, setbacks, existing structures, and parking all factor in. We review your property against current Boise zoning early — before design — so you know what is possible.

Mother-in-law suite or backyard cottage?

A suite attaches to or sits within the main home; a cottage is detached. Both are full living units — the right choice depends on your lot, budget, and how you plan to use it.

How long does it take to build an ADU in Boise?

Design and permitting usually take a few months, and a detached build typically runs four to eight months depending on size, site work, and finishes.
