How accessory dwelling units add usable space, property value and rental income in Kootenai County — what Idaho allows, and what it costs to build one.
An Accessory Dwelling Unit (ADU) is a smaller, self-contained home built on the same lot as your main house. It usually includes a kitchen, bathroom, living space, and private entrance.
Common types of ADUs:
Detached Tiny Homes (aka backyard bungalows)
Garage Conversions
Above-Garage Apartments
Basement Apartments
Attached Additions
In Idaho, detached ADUs are increasingly popular because they add usable space without altering the main home—and offer privacy for everyone.
Why Idaho Homeowners Are Building ADUs
Here in North Idaho, ADUs are in high demand because they’re:
✅ Flexible – Use it for guests, in-laws, a college kid, or your home office.
💰 Profitable – Rent it on Airbnb or long-term to offset your mortgage.
🏡 Valuable – Increase property value and resale appeal.
🛠️ Customizable – Built to match your vision, lifestyle, and lot layout.
Whether you’re in Coeur d’Alene, Sandpoint, Rathdrum, or Hayden, adding an ADU is one of the most cost-effective ways to grow your property’s function and value.
