Subdivision Approval in Unincorporated Weber County

Outside its cities, Weber County reviews subdivisions under Part II of the Weber County Code, the Land Use Code: Title 106 (“Subdivisions”) carries the process and Title 102 (“Administration”) names the decision-makers. Both were reorganized by Ordinance 2026-09, adopted May 26, 2026, after Ogden Valley incorporated as a city. This is a civic reference, not legal advice; the code text controls.

Who decides

One planning commission. Section 102-2-2 states that “Weber County has established a single Weber County Planning Commission that has jurisdiction over all of the unincorporated area in Weber County,” and Ordinance 2026-09 struck the former planning-area references to separate Western Weber and Ogden Valley commissions.

The County Commission is the legislative body. Under § 102-2-4 the Planning Commission “shall be an advisory board to the County Commission” on zoning map and land use regulation amendments. The County Commission adopts ordinances and fees but does not vote on plats.

Subdivision plats are administrative. Title 106 names an administrative land use authority for each step:

Step	Land use authority	Code section
Preliminary plat (other than a small subdivision)	Planning Commission	§ 106-1-4.040
Preliminary plat of a small subdivision, as defined in the Land Use Code	Planning Division Director	§ 106-1-4.040
Final plat, all subdivisions	County Planning Division Director	§ 106-1-5.040
Improvement plans (required before a final plat is “valid or effective”)	County Engineer	§ 106-1-5.040

Under § 106-1-6, a “simple boundary adjustment” that creates no new lots is exempt from the subdivision process and needs only a notice of consent; a “full boundary adjustment” goes through the applicable approval process.

The steps

Pre-application. The county’s Frontier portal lists pre-application meeting notes among the preliminary application items and gives 801-399-8371 to schedule a meeting.
Preliminary subdivision application (§§ 106-1-4.010 through 106-1-4.050). The applicant files through Frontier with a preliminary plat, title report, street connectivity plan, feasibility letters for culinary water, secondary water and wastewater, improvement plans and, where required, a geologic hazards report. The Planning Division circulates the application to county departments and, where applicable, UDOT; the applicant obtains outside-agency reviews. Once the application is complete, the county “shall observe the state’s timely review requirements and limited review cycles” (§ 106-1-4.030). The land use authority approves a complying application, with conditions as needed. Preliminary approval expires if final approval is not obtained within 18 months; the Director may grant up to two 18-month extensions (§ 106-1-4.050).
Final subdivision application (§§ 106-1-5.010 through 106-1-5.040). Requires the approved preliminary plat with conditions satisfied, improvement plans approved by the County Engineer, the final plat and an updated title report. The Director approves the plat; the county may withhold approval until a tax clearance letter is provided, and a record of survey must be filed with the County Surveyor before the Surveyor signs.
Recording (§ 106-1-5.050). The signed 24-by-36-inch mylar is recorded at the applicant’s expense with the County Recorder within 12 months of final approval, after the improvement guarantee is posted.

Where to find the agenda and how to comment

Utah Public Notice Website: Weber County Planning Division, which lists Weber County Planning Commission meetings and separate Administrative Review meetings.
County Planning Commission page with agendas, minutes and staff reports.
Project files are posted on the Frontier portal.

Title 106 does not itself require a public hearing on a plat. Section 102-2-6 requires meetings to be noticed under the open meetings law, and § 102-1-4 requires a final written decision mailed to the applicant and to anyone who requested notice in writing beforehand. Agenda contacts are listed on each notice (Planning Division, 801-399-8374). An agenda item is not a final approval.

What preliminary approval does and does not mean

Preliminary approval confirms the layout complies with county ordinances and lets the applicant move to improvement plans and a final plat. It creates no lots and permits no sales or building permits. Under § 102-1-4 a decision “is not final until the notice of final written decision is sent.” The subdivision exists only when the final plat is recorded.

Timelines and fees

Fees are set by ordinance in Weber County Code § 16-2-5 and reproduced on the Planning Division fee chart:

Fee	Planning Division	Engineering Division	Surveyor’s Office
Large subdivision (5 or more lots)	$815 + $25 per lot	$385 + $50 per lot	$400 + $25 per lot (or + $50 per condo unit)
Small subdivision (fewer than 5 lots)	$520 + $25 per lot	$230 + $25 per lot	$400 + $25 per lot (or + $50 per condo unit)
Re-review	$200	$200	$75
Subdivision change	$250	$100	$100
Final subdivision time extension	$225	—	—

Confirm current amounts with the Planning Division before relying on them.
