Basement finishing in Lehi, Utah.

About 3 in 4 Lehi homes were built in 2000 or later, so most basements here sit on newer foundations. Lehi City also has its own rules for basement apartments, from a parking stall to an owner affidavit recorded on the property. We plan your finish around those rules from the first sketch.

Lehi basements, by the numbers

Most Lehi homes went up after 2000.

Census numbers show about 3 in 4 Lehi homes were built in 2000 or later. The busiest decade was 2000 to 2009, with more than 8,500 homes. So most basement finishes here start with a newer foundation, not a 1950s fix-up.

A newer house does not mean a lighter permit, though. Lehi's Residential Basement Finish checklist asks for a floor plan with every window's location and size, plus the electrical, plumbing and mechanical layout. If a gas line moves or the furnace room changes, the city wants a gas piping diagram on paper too.

The plans go in through the city's online portal and come back stamped on every page. A printed copy of that stamped set has to be on site for every inspection. It lives in your basement until the last inspection is signed.

Thinking about a rental downstairs? Read the next section before you pick a layout. It can change where the door, the kitchen and the parking go.

Basement apartments in Lehi

What Lehi asks before a basement can be rented.

Lehi allows one accessory dwelling unit, or ADU, in an owner-occupied single-family home. The rules sit in Section 26.030 of the Lehi Development Code, under the state rules in Utah Code 10-21-303. Here is what they mean for your layout and your budget.

You have to live there

The owner signs an affidavit that the home is owner occupied, and the city records it against the property. If you sell, the new owner signs and records a new one to keep the unit legal.

Lot size and the restricted map

The lot has to be at least 6,000 square feet. The home also cannot sit in an area on Lehi's ADU Restricted Area Map, so check with the Planning Division before any plans get drawn.

One more parking stall, with a lit path

An internal ADU needs one off-street stall of at least 9 by 20 feet. It cannot be stacked behind your own cars, and a lighted walkway has to run from that stall to the unit's door. Budget for concrete and an outdoor light, not just the basement.

A locking door between the two

Lehi wants a real connection, like a locking door, between your home and the unit. If you stop renting, the space has to work as part of the house again. A planning permit comes first, then the building permit.

Good questions

Lehi basement finishing questions.

Can I rent out my finished basement in Lehi?
Yes, if it meets Lehi's ADU rules. You must live in the home, the lot must be 6,000 square feet or more, and the unit needs its own parking stall. While it is rented, Lehi requires an active ADU license. Check the current rules with Lehi Planning before you sign a lease.
How much does Lehi charge to approve a basement apartment?
The city's ADU FAQ lists a $25 application fee, and a $4,528 impact fee for detached units. The code also says to pay any impact fees that apply before you build. Building permit fees are separate, so ask the Building Division for your number.
Can my Lehi basement apartment be an Airbnb?
Not while it is an ADU. Lehi does not allow ADUs to be rented for less than 30 days. You can hold both an ADU permit and a short-term rental permit, but only one can be active at a time.
Is there a size limit for a basement apartment in Lehi?
Lehi's ADU FAQ says there is no size limit for an internal unit. The limits that bite are the lot size, the extra parking stall, and the locking door to your side of the house. A full basement can work if those line up.
What does Lehi need on the plans for a basement finish?
The city's checklist asks for a floor plan with dimensions and window sizes, the electrical, plumbing and mechanical layout, and the contractor's license number. An engineering packet or a gas piping diagram gets added if the job needs one. Everything is submitted online.
How are basement inspections booked in Lehi?
By phone, with 24 hours' notice. Lehi does not book inspections by voicemail, email or online. If the work is not ready when the inspector shows up, the city can charge a re-inspection fee, so each one should be called in only when that stage is done.
