The "Hidden" Square Footage: Navigating Unpermitted Additions When Selling Your Springville Home

by Lori Collins

Selling a home in Springville is usually a dream—between the mountain views and the "Art City" charm, buyers are always looking. But what happens when your home’s reality doesn't match the city’s records?

If you own a home built in the 90s (like many in our beautiful neighborhoods) and realized your 1,500 sq. ft. bungalow is actually a 3,600 sq. ft. footprint thanks to a finished basement and a large addition, you might feel like you've struck gold. However, if that work was done without permits decades ago, you’re facing a common but tricky real estate hurdle.

Here is the breakdown of the situation and how to handle it before the "For Sale" sign goes up.

The Problem: The "Paperwork Gap"

In your case, the Utah County Records show a 1,500 sq. ft. home. They recognize the basement exists, but not that it’s finished, and they have no record of that 600 sq. ft. (20' x 30') addition.

Even though this work was done in the late 90s—long before you even bought the place in 2010—the responsibility now falls on the current seller. This creates three main issues:

Appraisal Hurdles: An appraiser may struggle to give full value to unpermitted space, meaning a buyer’s bank might not loan them the full amount of your asking price.
Buyer Cold Feet: Modern buyers are wary of "unpermitted" work due to concerns about safety, structural integrity, or future city fines.
Liability: You must legally disclose known unpermitted work. Failing to do so can lead to major legal headaches after the closing.

What You Should Do: A Step-by-Step Guide

1. The "As-Is" Disclosure Strategy

The most common route is to sell the home "As-Is" regarding the square footage. You disclose everything clearly: "Basement finished and rear addition completed by previous owner without permits." * Pros: No construction dust or city inspections for you.

Cons: You likely won't get the same "price per square foot" as a fully permitted home.

2. Seek Retroactive Permitting (The "Safe" Route)

Springville City’s building department has seen this before. You can approach them about a Certificate of Occupancy or a retroactive permit.

The Process: An inspector will come out. They may require you to open a small section of drywall to inspect wiring or plumbing.
The Result: If it passes, your home’s official record is updated. This can significantly increase your home's appraised value.

3. Consult a Specialized Appraiser

Before listing, hire a private appraiser who is familiar with unpermitted additions in Utah County. They can give you a "market value" versus a "permitted value," helping you and your realtor set a realistic price that won't fall through during the buyer's financing stage.

4. Focus on the "Grandfathered" Aspect

Since the work was done in the 90s, much of it may be "grandfathered" in regarding certain modern codes, but it still needs to be safe. Having a professional home inspection done before you list can give buyers peace of mind that even though it lacks a permit, it was built to last.

The Bottom Line

Don't panic! Many homes in Springville have "extra" space that isn't on the tax rolls. The key is transparency. By being upfront about the history of the home, you build trust with buyers and protect your investment.

Determining the value of a home with unpermitted space is part science, part strategy. In Springville, where the market has remained relatively steady into 2026, you have a significant amount of "hidden" equity, but unlocking it requires careful navigation of appraisal and disclosure rules.

Part 1: How Much Is It Worth?

In Springville, the median sale price per square foot currently hovers around $225 to $252. However, unpermitted square footage is rarely valued at the same rate as permitted space. Here is how an appraiser or buyer will likely view your 3,600 sq. ft. total:

Area	Size	Estimated Value Logic
Main Level (Permitted)	1,500 sq ft	Full Market Value: ~$240/sq ft. This is your "guaranteed" value.
Finished Basement	1,500 sq ft	Partial Value: Usually 50–70% of main-level value. Since the city knows it exists but not that it's finished, you get credit for the space, but a "deduction" for the lack of a permit.
Addition (Unpermitted)	600 sq ft	Variable Value: This is the wildcard. If it's high quality, a buyer may pay for it, but an appraiser for a bank may give it zero value if they cannot verify it meets code.

The "Value Gap" Estimate:

Permitted Value: If fully permitted, your home might be worth ~$650,000 – $725,000.
Current State: You should expect to list closer to $575,000 – $615,000 to account for the "risk" a buyer takes on and the likely appraisal shortfall.

Part 2: Disclosure Statement Template

In Utah, you are legally required to disclose "material defects," and unpermitted work qualifies. Using a clear, professional disclosure protects you from future lawsuits.

Note: This template should be attached as an addendum to the standard Utah Seller’s Property Condition Disclosure.
