What to Expect: ADU Permitting Process

Boise’s pre-approved ADU program is designed to simplify what has traditionally been a complex process. While every property is unique, most homeowners can expect the following steps:

Confirm Your Property is Eligible

We’ll help verify zoning, size limits, and any special conditions (such as Historic District requirements).

Choose Your ADU Plan

Select from the city’s pre-approved designs that best fit your property and goals.

Create a Simple Site Plan

A basic layout showing where the ADU will sit on your property, along with access and existing structures.

Concept Review with the City

A quick, high-level review with a city planner to confirm everything is on the right track before moving forward.

Planning Application & Approval

Submit final documents for city review. Once approved, you’re ready to move to building permits.

Building Permit & Construction

After permits are issued and fees are paid, construction can begin.

Good to Know:

Even with pre-approved plans, homeowners should plan for standard costs such as permit fees, impact fees, and site work (utilities, access, etc.).


Our team helps guide you through each step—making the process as smooth and efficient as possible.
