Should I buy an unfinished basement in Herriman?

Usually yes, and in Herriman specifically it is often the smarter of the two buys.

Unfinished basements are the norm on newer Utah construction, and Herriman is mostly newer construction. Builders deliver the main floors finished and the basement as a shell, because it lets them sell at a lower price and lets the buyer decide what the space becomes. It is not a defect. It is how most of the south valley’s housing arrives.

The question is whether the unfinished space is an opportunity for you or a cost you have not budgeted. That depends on three things: how you will use the house, whether you will actually finish it, and how you are financing.

The seller’s side of the same question is should I finish the basement before I sell.

Why Utah homes come this way

Basements are standard in northern Utah because the frost line makes a deep foundation necessary anyway, and once you are digging that deep a basement is nearly free square footage. So the house gets one.

Finishing it is separate work — framing, electrical, plumbing, drywall, flooring, egress windows for any bedroom — and builders leave it undone to hold the sale price down. The new-construction market in Herriman is largely built this way, and so is the near-new resale market that came out of it.

The result is that “unfinished basement” in Herriman is not a warning sign. It is the default.

What it does to the price

Two otherwise identical houses, one with the basement finished and one without, will not sell for the same money. The finished one is worth more, because it has more usable space.

But the gap is rarely the full cost of finishing. Sellers who finished their basement generally do not recover every dollar they spent, which means the buyer of the finished house is getting the space at something of a discount to what it cost to create.

That cuts both ways. If you want the space and will use it, the finished house can be the better value even at the higher price. If you do not need it yet, the unfinished house lets you defer the cost until you do — or never spend it.

What it does to the appraisal

Unfinished square footage does not count the way finished square footage does. An appraiser values finished living area and treats the unfinished basement as a lesser contribution. If the basement is already finished as a separate unit, buying a house with a basement apartment in Herriman covers what changes.

That matters for two reasons.

When you buy: if the appraisal comes in low, it will not be because the appraiser undervalued the unfinished space. Do not pay for the basement as though it were finished.

When you sell: if you finish the basement well, with permits, the square footage becomes countable and the house appraises as the larger home it now is. If you finish it badly or without permits, an appraiser may not credit it at all.

The honest cost of finishing

Finishing a basement is a real project, and I am not going to put a figure on it here because it varies enormously with size, finish level and whether you are adding a bathroom or a kitchen. Get quotes for the specific house.

What I will say is that buyers consistently underestimate it in three ways:

Egress. Any bedroom needs a code-compliant egress window. If the house was not built with the window wells in place, adding them means cutting the foundation, and that is not a small line.

Plumbing. If the builder stubbed in a bathroom rough-in, you are ahead. If not, adding one means breaking the slab.

Permits and time. Finishing a basement in Herriman means permits and inspections with the city. That is right and it protects your resale, but it is slower than a weekend project.

Get an honest quote before you buy on the assumption that you will finish it. The number sometimes changes the decision.

The things to check in any Herriman basement

Moisture. Look for staining on the foundation walls, efflorescence, any smell. A dry basement is the whole foundation of the project. A home inspection that flags moisture is one to take seriously rather than negotiate around.

Radon. Parts of Utah have elevated radon and it accumulates in basements. Test before you buy, and again after you finish, because finishing changes the air flow. Mitigation is straightforward and worth doing.

Ceiling height and mechanicals. Where the furnace, water heater and ductwork sit determines what layout is possible. A basement with mechanicals in the middle is harder to finish well than one with them tucked in a corner.

Window wells and drainage. Where does the water go when it rains hard? Check the grading and the wells.

What the builder roughed in. Bathroom stubs, electrical for a future kitchen, a framed-out furnace room. A builder who planned for the finish saved you money.

When the unfinished basement is the wrong buy

You need the space now and cannot fund the finish. A family that is already tight on the main floor and cannot afford the basement project has bought a smaller house than they needed at a price that assumed they would grow into it.

You are financing at the limit. The finish comes out of savings or a second loan. If the purchase uses everything, the basement stays a shell for years.

You will not do it. Plenty of Herriman basements stay unfinished for a decade. If you are honest that you are unlikely to take on the project, buy the finished house or buy the smaller house — not the unfinished one on the theory of someday.

When it is the right buy

You will finish it to your own plan. The unfinished basement is a blank floor. Buyers who finish it get exactly the layout they want — a suite for a parent, a rental with a separate entrance where zoning allows, a home gym, a theater — rather than someone else’s choices.

You want to grow into the house. Buy the main floors you need today and add the basement when the family or the budget arrives.

You are price-sensitive on entry. The unfinished house is the lower purchase price for the same footprint. A townhome is the other way in at a lower price, with a different set of trades.

What I actually see happen

I am Kelsey Earl, a Realtor with Keller Williams South Valley, and the unfinished basement is where Herriman buyers most reliably underestimate money.

The pattern: a buyer chooses the unfinished house to save on the purchase, plans to finish it “next year,” gets one quote, and the project sits. That is fine if they did not need the space. It is a problem if they bought a three-bedroom on the main floor for a family that needed five.

The buyers who do it well decide before closing whether they will finish, get a real quote, and either fund it or choose the finished house instead. The decision made early is almost always the right one.

What to do next

For any house you are considering, get a finishing quote during due diligence, not after. Then decide with the real number in hand whether the unfinished house plus the finish beats the finished house at its price.

Before you price the finish, find out what the city will allow — whether you need a permit, and what else the zoning decides, is the call to make first.

If you are weighing the value of your own home with a finished or unfinished basement, the difference matters to what it is worth and how I would price it.
