Complete Guide to Subdivision Plat Surveys and Development in Utah.
How a parcel becomes recorded lots: lot splits versus subdivisions, the six steps from concept to recorded plat, what cities review, and real plats from our files. From a firm that has prepared 529 subdivisions and plats since 2000.
How Does Subdividing Land Work in Utah?
A licensed surveyor establishes the parcel’s boundary and maps the terrain and utilities. An engineer designs the lots, streets, grading and utilities. The city or county reviews a preliminary plat, then a final plat; improvements are built or bonded; and the plat is recorded with the county and the lot corners are set.
Small splits can take a few months. Larger subdivisions with new streets often take six months to a year, mostly in review and construction.

Lot Split, Minor Subdivision or Major Subdivision?
The right path depends on how many lots, whether new streets are needed, and your city’s ordinance.
Lot split
One parcel into two, often with new legal descriptions. Some Utah cities allow simple splits without a full plat; others require a minor subdivision.
Minor subdivision
A handful of lots on an existing street, like the one-, three- and four-lot subdivisions we plat every year in Spring City, Mona, Fairview and Nephi.
Major subdivision
New streets, water and sewer, and dedication to the city, like Nebo Meadows (42 lots) and Hawks Landing (16 lots).
Commercial subdivision
Lots for businesses, with shared access, utility and sign easements, like Reed Ridge on Nephi’s Main Street.
Plat amendments & adjustments
Moving lot lines, combining lots or revising a recorded plat. 30 lot-line adjustments in our records, plus many plat revisions.
Agricultural splits & annexations
Dividing farm ground or bringing it into a city, often with roads, sewer and water engineering.
Six Steps From Raw Land to Recorded Lots
The order is the same across Utah; the details, fees and review times vary by city and county.
Feasibility & concept
Check zoning, lot sizes, access and utility service, then sketch a concept layout. Many cities want a concept meeting first.
Boundary & topographic survey
Establish the outer boundary, recover section and block corners, and map the terrain and existing utilities.
Preliminary plat & engineering
Lot layout, streets, grading, drainage, water and sewer, reviewed by the planning commission and city engineer.
Final plat
The signed, stamped plat with lot dimensions, easements, dedications and the owner’s and surveyor’s certificates.
Improvements
Roads, curb and gutter, water and sewer built or bonded, with construction staking from the same survey control.
Record & monument
The plat is recorded with the county, and lot corners are set so every buyer can find their lines.

What Keeps a Subdivision on Schedule
Habits from decades of platting in central Utah.
Survey before you sketch.
A concept drawn on a county parcel map can lose a lot when the real boundary comes in short. We survey first, then lay out lots.
Find water and sewer early.
Lot yield often depends on where sewer can reach by gravity and how much water the city can serve. Ask before you design.
Write the easements into the plat.
Access, utility and irrigation easements are easiest to create on the plat, before lots have different owners.
Set the corners when you record.
A recorded plat with no monuments in the ground leads to fence disputes. We set lot corners so buyers can find their lines.

Subdivision Questions, Answered.
What is a subdivision plat?
A recorded map that divides a parcel into lots, shows streets and easements dedicated to the public, and gives every lot's dimensions. Once recorded with the county, lots can be sold by lot number.
What's the difference between a lot split and a subdivision?
A lot split divides one parcel into two, often with new deed descriptions. A subdivision creates several lots on a recorded plat and may add streets and utilities. Each Utah city and county decides which applies, so check your local ordinance or ask us.
How long does a subdivision take in Utah?
A simple minor subdivision can take a few months from survey to recording. Larger subdivisions with new streets and utilities often take six months to a year or more, mostly driven by city review and construction of improvements.
How much does a subdivision plat cost?
It depends on the number of lots, whether new streets and utilities are needed, and the city's requirements, so we quote each one by scope. The boundary survey that starts the process runs from $1,025 for a recorded lot, and larger parcels more.
Do I need an engineer as well as a surveyor?
For anything beyond a simple split, usually yes. Streets, grading, drainage, water and sewer need engineering. Our engineer, J. Brett Ludlow, PE, works in the same office as our surveyors.
Who approves a subdivision?
Usually the city's planning commission and city council, or the county for unincorporated land, after review by the city engineer and utilities. The final plat is then recorded with the county recorder.
What should I bring to a first meeting?
The parcel number, your deed, how many lots you're hoping for, and any conversations you've had with the city. We'll check zoning, access and utilities and tell you what's realistic.
Thinking About Subdividing?
Send the parcel number and how many lots you’re hoping for. We’ll check zoning, access and utilities and tell you what’s realistic, then quote the survey and engineering as a fixed fee.
