Thinking about ways to add value to your Salt Lake City home — or generate rental income without buying a second property?
An ADU (Accessory Dwelling Unit) might be exactly what you're looking for.
Whether it's finishing your basement into a legal apartment, converting your garage, or building a backyard cottage — ADUs are one of the most powerful tools available to SLC homeowners right now. And Salt Lake City's 2023 ordinance update made them easier to build than ever.
Here's what you need to know at a glance 👇
✅ One ADU per lot — internal or detached
✅ Internal ADUs have no maximum size and are exempt from impact fees
✅ Detached ADUs can be up to 1,000 sq ft
✅ No minimum lot size required
✅ Owner must live on the property (primary or ADU)
✅ Short-term rentals (Airbnb/VRBO) are prohibited — long-term rentals are fully permitted
💰 Costs range from $75,000 for a basement conversion up to $400,000+ for a detached new build — and there are city-backed financing programs available for Westside homeowners.
We've put together a complete guide covering rules, costs, financing, permit process, and what an ADU can do for your property value. Link in the comments below!
