The Utah land and build guide
Buying land to build a house in Utah
Buying land to build a house works best in a set order. Line up the money and a builder, buy land you can legally build on, get the permit, then build. The ten steps below name the Utah offices that sign off before anyone digs.
My build
- Talk to a lender
- Builder walks the land
- Legal lot, water, septic
- Offer with time to check
- Close on the land
- Plans and the permit
- Build and inspect
- Final inspection
Phase 1 of 3
Before you buy the land
The money, a builder's view, the land checks, and an offer that leaves time to make them.
The short answer
From bare land to keys, in plain words
In shortMoney and a builder come first, then land you can legally build on, then the permit. Nothing gets dug until that permit is issued.
Start with a lender and a builder, not a listing. What you can borrow sets your land budget, and a builder who walks a lot can tell you what building there will take. Then buy land you have checked: a legal lot with access, water you can use, and ground that takes a septic system or a sewer line.
Once you own the land, the house work starts on paper: a survey, a soils report, a plan, and the water, septic and power pieces. They all feed one permit from the city or county, and only then does a shovel move. For the design and the build itself, building a custom home in Utah goes deeper.
How long it takes
How long the build takes on your own land
In shortThe build alone averaged about 10.5 months in 2025 when a contractor built on the owner's land. The land search, the design and the permit come before that.
A contractor building on the owner's land, from start of work to completion
A home the owner built
A home a builder put up to sell
Those three numbers cover the build itself, from the first day of work to the last. Getting from the permit to that first day added about 1.4 months more for contractor builds and 1.7 for owner builds.
The land search and the design come before all of that, so lot to keys often runs past a year. Weather, the offices in your county and your own choices can stretch any part of it.

Step 1
Before you shopCan you finance the land and the house together?
In shortOften, yes. Talk to a lender before you shop, because the loan path decides how the land purchase and the build fit together.
Most people pay for land and a house in one of three ways. A lender can show you which ones fit you, and what each one asks of you, before you fall for a lot.
| The path | How the land gets bought | While the house goes up |
|---|---|---|
| Cash or a land loan, then a build loan | You buy the lot first, with cash or a land loan. | A separate construction loan pays the builder. A mortgage replaces it at the end. |
| One construction-to-permanent loan | The same loan can pay for the lot. | It pays the builder in stages, then becomes your mortgage. |
| The builder's own financing | Ask whether it covers the lot or only the house. | Set by the builder and its lender. Read the terms closely. |
Land loans usually ask more of you than a home mortgage, and they get tighter the rawer the land is. That alone is a good reason to make the lender your first call.
If you already own the lot when a one-closing build loan starts, the loan is set up differently, and the land itself can count in your favor. Ask your lender how that works before you decide to close on the land by itself.
Construction loans pay the builder in stages, called draws, as each stage is done and checked. Interest is generally owed only on what has been paid out so far. FHA, VA and USDA each have a build loan with one closing, offered through the lenders that choose to make them. VA construction loans in Utah covers the VA version.
A builder's bid usually covers the house. Ask what it leaves out, because these costs often sit outside it:
- The land
The price of the lot, plus its own closing costs.
- Design
The plans, any engineering, and the site plan the county asks for.
- Permits and impact fees
The permit fee, plus the impact fees your city or county charges.
- Hookups
Connection fees for water, sewer and power, or a well and a septic system.
- Site work
Getting the ground ready, such as grading and the driveway.
- The finishing touches
Landscaping outside, and window coverings inside.
- Carrying costs
Interest on the loan while the house goes up.
I'm a mortgage lender as well as a REALTOR, so that first call can be with me, or with any lender you choose.
You do
- Talk to a lender before you shop
- Ask which loan path fits a lot and a build
- List the costs outside the builder's bid
Lender or office does
- Your lender shows what you can borrow
- Your lender explains which path fits
Step 2
Before the land closesShould you buy land or find a builder first?
In shortWork on both at once. A builder who walks the land before you close can price the work on that lot while you can still walk away.
People argue about this one, and a lot of the builder-first advice comes from builders. My answer sits in between: call the lender first, then shop for land and a builder side by side.
The point is timing. A builder who walks a lot before your due diligence window closes can spot what will cost extra to build on, and fold it into a rough price. After closing, those surprises belong to you.
Land first
- You find the lot you love
- It may cost more to build on than you planned
- The house you want may not fit it
Builder first
- You know the house and who builds it
- You may only see the lots that builder offers
- The plan may not suit the land you find
Doing both at once avoids most of each risk. Get more than one builder's view of the same lot.
The builder visit and the land checks happen before closing; the survey, the plan and the utility paperwork follow once you own the land. Nothing physical happens on the lot until the building permit is issued.
You do
- Get two or three builders' views
- Ask for a site visit before closing
- Keep shopping while you compare
Your agent or builder does
- Your builder walks the lot
- Your builder gives a rough price for this lot
Step 3
While you shopWhy some land is not buildable
In shortA lot can look perfect and still fail on paper or in the ground. Ask the offices that decide before you buy.
The listing says land, and the price looks right. Before you fall for it, check that it can legally take the house you want. Each of these can stop a build or add a big cost, and each one has an office that can answer for it.
- Not a legal lot
Where a split needs a plat, a piece sold off without an approved, recorded plat can be yours on paper and still not be a lot you can build on. Ask the city or county planning office.
- Zoning and setbacks
Zoning sets what you may build, and setbacks and easements push the house back from each line. Ask the planning office where a house can go.
- No legal access
A road you can drive is not always one you have a right to use. The title report and a survey show what is recorded.
- No water you can use
In Utah, water rights are separate from the land and do not come with the deed on their own. A new well needs a water right first. Ask the Division of Water Rights or the water provider.
- Soil that fails for septic
Without a sewer line, the local health department has to accept a soil test before it issues a septic permit. Ask the health department.
- Mapped hazards
Flooding, soil that settles when wet, and ground cracks can each call for a study first. Ask the county, and look the spot up on the state's hazards map.
- A wildlife check
In Iron County, the first step toward building is checking the land against the state's Utah prairie dog clearance map. Ask the county building office.
- Wildfire rules
Near wildland, your city or county may add fire rules for how you build. Ask the building or fire office early.
The ground left for the house is smaller than the lot. Setbacks, easements, the well, the septic field and drainage all claim their own space, and the county wants every one of them on your plot plan.
Soil that settles when wet sounds odd, but it is real. The Utah Geological Survey's Cedar Valley study, released in May 2026, named that kind of soil and flooding as the valley's costliest hazards. It called ground cracks from falling groundwater a growing concern, above all for new building in Enoch. I live in Cedar City, and Enoch is just up the road, so I pay attention to this one. Radon is common in the valley too, so testing inside the house is advised.
The survey's online Geologic Hazards Portal shows what is mapped for a spot. Treat it as a first look, because a city or county can ask for a study of your own lot, and Iron County asks for soils reports on every new home.
You do
- Ask planning if it is a legal building lot
- Confirm water, access and septic in writing
- Look the spot up on the hazards map
Your agent or builder does
- Your agent pulls what the listing and records show
- Your builder flags what will cost extra
Lender or office does
- Planning answers the lot and zoning questions
- The health department answers on septic
Step 4
Inside your due diligence windowWriting the offer on land you plan to build on
In shortBuild time into the contract to answer the land questions. Then use every day of it.
Utah's state-approved forms include one purchase contract, plus add-on forms called addenda. None of them is a contract made just for land. For land, agents commonly use the Real Estate Purchase Contract for Land that Utah REALTORS publishes for its members, last updated in November 2024. A licensee may also use a form a lawyer prepared when no state form fits.
Whatever the form, the window that matters most is due diligence, the time your contract gives you to check the land before you are locked in. Fill it with the questions from step 3: legal lot, zoning, access, water, septic or sewer, power and hazards. Your contract sets the length, so ask for enough time to get real answers.
Ask in writing which water rights, if any, come with the land. Get the title company's report early too, so you see the recorded easements before the window closes.
Get it in writing. If the seller says water, access or a septic approval comes with the land, make the contract say so.
You do
- Ask for a window long enough for the checks
- Get the water rights answer in writing
- Read the title report for easements
Your agent or builder does
- Your agent writes the offer on the land form
- Your agent tracks your due diligence date
Lender or office does
- The title company sends its report
Own a home now?
Selling first, then building?
If the build depends on the money in your current home, the order matters. You may also need a place to live while the house goes up, often for a year or more.
Tell me about your home and your land plans, and we will work out the order together. No pressure, and no obligation.

Phase 2 of 3
Own the land, get the permit
Close, fit the house to the lot, line up utilities, and get the county's yes.
Step 5
On the date in your land contractClose on the land
In shortThe deed records at the county, and the land is yours, along with its taxes and anything the checks missed.
Closing on land works much like closing on a house. A title company runs it, and the deed gets recorded with the county. If one loan will cover the lot and the build, ask your lender whether the land should close now or with the build loan.
From the day you own it, the land's property taxes are yours. Vacant land does not get Utah's primary home exemption, so the whole value is taxed until the house can qualify. If the land sits in greenbelt and the house will take part of it out, read step 10 before you close.
You do
- Sign and fund at the title company
- Keep the deed and title policy safe
- Note when the land's taxes start
Your agent or builder does
- Your agent checks the closing numbers with you
Lender or office does
- The title company records the deed
Step 6
Weeks to months, by county and designerSurvey, soils and a house plan for this lot
In shortThe house has to fit this ground. A survey, a soils report and a site plan come before the drawings are final.
A survey marks the lot lines and shows the easements, so the house lands where it is allowed to. A soils report then tells the engineer what the ground can hold. Iron County's posted checklist asks for soils reports on the footings and on the backfill and final grade of every new home.
With those in hand, the plan gets drawn for the lot, not the other way round. The county will want a plot plan, a drawing of the lot from above. It shows the house, the setbacks to each line, the driveway, every utility and any well, ditch or drainage. A full set of house plans goes in too, and some need engineering.
Building in Southern Utah? Ask early about the geologic hazard form. Iron County's packet has one, and the Cedar Valley study in step 3 shows why.
You do
- Order a survey
- Get the soils report
- Have the plan drawn for this lot
Your agent or builder does
- Your builder or designer fits the plan to the lot
Lender or office does
- The county reviews the plot plan
Step 7
Each office runs its own calendarWater, sewer or septic, and power
In shortThe county wants proof of water and a plan for waste before it issues a permit. Power needs its own call.
Iron County's permit form asks where your water will come from: a public system, a well, hauled water or a spring. Each answer brings its own paperwork, and the waste side works the same way.
- 01Public water
Proof of water from the provider, or a paid water hookup receipt.
- 02A well
A valid water right comes first. Once it is approved, the Division of Water Rights issues a Start Card, the permit to build the well. A licensed driller builds it and files a log when the work is done.
- 03Hauled water
A tank you fill by truck. Ask the county whether it accepts that for a new home before you count on it.
- 04Sewer
A paid sewer hookup receipt and a connection letter from the provider.
- 05Septic
A soil test that the local health department accepts, then its septic permit, before anything is designed or put in. In the five southwestern counties, that office is the Southwest Utah Public Health Department.
- 06Power
Rocky Mountain Power or a member-owned co-op, such as Garkane Energy or Dixie Power, each with its own rules for running a new line. Your builder also needs temporary power on site before the house exists.
Utah's well rules changed in 2022, so older advice may be out of date. There is no exemption that lets a home well skip the water right.
You do
- Decide your water source
- Start the septic soil test or the sewer letter
- Call the power provider about a line
Your agent or builder does
- Your builder sets up temporary power
Lender or office does
- Water Rights issues the Start Card
- The health department issues the septic permit
Step 8
No digging until it is issuedWhat it takes to get a building permit in Utah
In shortOne building permit from your city or county, with every other approval inside it. Then 811 before anyone digs.
Every city and county in Utah builds to one statewide construction code, based on the International Residential Code with Utah's own changes. Inside city limits, the city sets the land rules; outside them, the county does. In some small towns, the town signs off first and the county issues the permit.
The permit is the gate. Planning, your water source, the health department or a sewer letter, the power company and the soils reports all feed it. The dashed boxes apply only in some places: the wildlife check inside Iron County's clearance area, and fire rules where a local code adopts them.
Iron County shows what a full packet holds. As of November 2026, its posted checklist for a new home asks for these pieces:
- 01A permit information sheet
Including where your water comes from.
- 02Water and waste
Proof of water or a paid hookup receipt, plus a septic permit or a paid sewer hookup with a connection letter.
- 03A plot plan
The lot from above, with setbacks, utilities, easements, ditches, drainage, the driveway and any wells or springs.
- 04Soils and geology
A geologic condition form, plus soils reports for the footings and the final grade.
- 05A prairie dog letter
The Utah prairie dog clearance check. Inside the clearance area a survey is required, and the Division of Wildlife Resources helps with it.
- 06House plans
A full digital set, which may need engineering.
- 07Owner-builder certificate
Only if you build it yourself. Step 9 has the limits.
- 08Town sign-off
For land inside one of the incorporated towns.
From Iron County's posted building packet and prairie dog form, as of November 2026. Your county's list may differ, so confirm it with the building office.
Fees come in three kinds, and a new home can owe all three: the permit fee, the hookup fees and impact fees. An impact fee pays for the load a new home puts on public systems like water lines and roads. By law it cannot be more than the local study behind it supports.
Near wildland, your city or county may have adopted Utah's wildland urban interface code, which adds fire rules for how you build. Since 2026, owners of buildings in a city's high risk area also pay a yearly wildfire fee, collected by the county. Ask the building or fire office before the plans are final.
No digging yet. Iron County's packet says it in bold: no digging, trenching or excavation until the permit is issued. After that, whoever digs must call 811, Blue Stakes, at least 48 hours and no more than 14 days before the work starts.
You do
- Ask your building office for its list
- Gather each approval
- Wait for the permit before any digging
Your agent or builder does
- Your builder files for the permit, if you hire one
Lender or office does
- Planning and building review the plans
- The city or county issues the permit
Phase 3 of 3
Build and move in
Inspected stages, a final sign-off, then the keys and the paperwork that follows.
Step 9
About 10.5 months on average (US, 2025)Who builds it, and how you stay protected
In shortHire a licensed contractor on a written contract, or build it yourself within Utah's limits. Inspectors check each stage either way.
Most people hire a licensed general contractor. Look up the license on the state's license lookup before you sign, then put the whole job in a written contract.
That contract does more than set the price. Under Utah law, if the home will be yours to live in, and you sign a written contract with a licensed contractor and pay that contractor in full, a company or supplier the contractor hired and did not pay generally cannot keep a lien, a legal claim, on your home. Ask a real estate attorney how it applies to your contract.
Ask before you sign. Ask how your contract protects you from liens, and who checks each stage before a payment goes out.
You can also be your own builder. A sole owner may build one home a year, and no more than three in five years, on their own land for their own use, without a contractor license. You sign an owner-builder certificate with the permit. Anyone you pay for licensed work, like wiring or plumbing, still needs a license, and paying someone who does not have one can be a crime.
Building it yourself also means you hire each crew directly, so the lien protection above may not work the same way. Talk to an attorney before you start.
As the house goes up, an inspector checks each stage before it gets covered, from the footings and framing to the plumbing, wiring, heating and insulation, then a final. Your loan pays the builder in draws that follow those stages, so each payment waits for its stage to be done and checked.
You do
- Look up the license before you sign
- Sign a written contract
- Keep a record of each payment
Your agent or builder does
- Your builder runs the work
- Your builder books the inspections
Lender or office does
- Inspectors pass each stage
- Your lender pays out each draw
Step 10
Certificate of occupancy firstFrom final inspection to living there
In shortNo one moves in until the building official issues a certificate of occupancy. Then the loan and the tax paperwork follow.
After the final inspection, once the house meets the code, the building official issues a certificate of occupancy. Until then, no one may live in it.
Then the construction loan ends. With one loan, it turns into your mortgage. With two, your new mortgage pays the build loan off. A few tax jobs follow:
- 01File for the primary home exemption
For a primary home, Utah taxes only 55% of its market value. Vacant land does not get it, but a home still under construction can, if the county assessor decides it will be your primary home. File with the assessor.
- 02Mind the one acre cap
The exemption covers no more than one acre per home. The rest of an acreage parcel is taxed at full market value, unless it qualifies for greenbelt.
- 03Greenbelt land
If you build on land in greenbelt, a rollback tax can come due for up to the five years before the assessor's notice. Tell the assessor within 120 days of taking the land out.
- 04January 1 counts
Utah values property for tax at its market value as of January 1 each year. Ask your assessor how a house still going up on that date is counted.
You do
- Pass the final inspection
- Get the certificate of occupancy
- File with the assessor for the exemption
Lender or office does
- The building official issues the certificate
- Your lender turns the build loan into a mortgage or pays it off
- The assessor decides the exemption
After the steps
Weighing it up
Whether building beats buying a finished home, and where I fit in.
Build or buy?
Is building cheaper than buying a finished home?
In shortOften not, once every cost is counted. What you get is a home planned for that piece of ground.
Compare the whole bill, not the lot price plus a builder's base number. Add the site work, the permit and impact fees, the hookups, a well or septic system if you need one, and the interest you pay while the house goes up. The cost list in step 1 has them all.
Time counts too. A finished home can be yours within weeks of an accepted offer, while a build on your own land often runs past a year. You may be paying rent or another mortgage the whole time.
So is a set budget enough to build? It depends on the lot more than people expect. The only real test is a builder's bid on your actual lot, set next to finished homes for sale in the same area. What building gets you is a house drawn for that lot, its views and its sun, with the rooms you chose.
Building with me
Land, loan and build questions in one place
In shortI sell real estate, and I also make mortgage loans. On any one deal I take one role, and you know which one up front.
I have more than 20 years living in Southern Utah. In Iron, Washington, Kane, Garfield and Beaver counties, I can be your agent on the land myself, or your lender on the build loan, but never both on the same deal.
Elsewhere in Utah, a partner agent I trust is your local expert on the land. If you buy through an agent I refer, their brokerage pays mine a referral fee out of their own pay, never an added cost to you. You are free to pick any agent and any lender. How I work has the details, and you can tell me about your land plans whenever you are ready.

Questions, answered
What people ask about buying land to build
Work on both at once. Talk to a lender first, then have a builder walk the land before you close, so the work on that lot gets priced while you can still walk away. Builders who tell you to start with a builder may be selling, so get more than one view.
It may not be a legal lot, such as a piece split off without an approved, recorded plat. The zoning or setbacks may not allow your house, there may be no legal access or no water you can use, or the soil may fail for a septic system. A mapped hazard or a protected species can also call for a study first. The city or county planning office can answer the legal lot question before you buy.
Often, yes. A construction-to-permanent loan can pay for the lot and the build, then become your mortgage. If you already own the lot, it can count in your favor. Programs and lender rules vary, so ask a lender before you buy the land.
In 2025, homes built by a contractor on the owner's land took an average of 10.5 months from start to finish across the US, and owner-built homes took 12.8. Getting from the permit to the start of work added more than a month, and the land search and design come before that. Lot to keys often runs past a year.
Yes, within limits. A sole owner may build one home a year, and no more than three in five years, on their own land for their own use. Anyone you pay for licensed work still needs a license, and the county will ask you to sign an owner-builder certificate.
A building permit from the city or county, plus the pieces it asks for: proof of water or a well permit, a septic permit or a sewer connection, a site plan, and in some counties geologic reports or a wildlife check. No digging until the permit is issued.
Often not, once you add the site work, the permit and impact fees, the hookups, and the interest you carry while the house goes up. In return, you get a home planned for that piece of ground. A builder's bid on your actual lot is the only real way to compare.
