Tremonton, UT Zoning

Euclidean-zoning. 14 districts · 7 overlays · 4 applicable state preemptions.

Overview

Code type
euclidean
Naming convention
Residential: RR-1 (rural), R1-20/R1-12/R1-10/R1-8 (SF by lot size), RM-8/RM-16 (multi-family, du/ac-encoded). Commercial: CD (central dev), CG (general), CH (highway), CN (neighborhood). Industrial: MD (manufacturing/distribution), MD-B (business park), MG (general industrial). Project-specific overlays named after subdivisions (Spring Hollow Legends, Tremont Center, Aspen Grove, Edgewood, Aspen Ridges, Rivers Edge).

Standard Euclidean small-city Utah code; chapters are 1.07 (residential), 1.08 (commercial/industrial), 1.09 (mixed use), 1.16 (overlay zones). All Chapter 1.16 overlays are project/subdivision-specific (no traditional hazard overlays like floodplain codified as overlay districts — FEMA NFIP compliance handled via separate flood-damage-prevention ordinance). 1000 North Corridor Preservation is the closest to a traditional corridor overlay.

Worth knowing
  • Five-Tier Single-Family Lot-Size Ladder. RR-1 (43,560 sf) → R1-20 → R1-12 → R1-10 → R1-8 creates an explicit five-step density gradient encoded in district names (R1-N = N×1,000 sf minimum). This is finer-grained than most small Utah cities, reflecting Tremonton's agricultural-to-urban transition zones. Uniform 36 ft / 2.5-story height cap across all residential districts; density is modulated entirely via minimum lot area and setbacks, not height.
  • No Traditional Floodplain or Hazard Overlays in Chapter 1.16. Chapter 1.16 overlays are EXCLUSIVELY project/subdivision-specific (Spring Hollow Legends, Tremont Center, Aspen Grove RV, Edgewood, Aspen Ridges, Rivers Edge, 1000 North Corridor). Floodplain management is handled outside the zoning overlay framework — via FEMA NFIP compliance and a separate flood-damage-prevention ordinance referenced through Chapter 1.19 supplementary regulations rather than codified as an FP overlay district. This differs from Brigham City (same county), which does use FP/CC/HS hazard overlays.
  • Bear River Floodplain Constraint — Handled Via Separate Ordinance. Significant Bear River floodplain coverage on Tremonton's northern and western fringes triggers FEMA NFIP development review (elevation above BFE, compensatory storage) via the city's flood-damage-prevention ordinance — NOT via a codified Chapter 1.16 overlay zone. Bear River floodplain materially constrains residential and commercial development on northern and western parcels regardless of base district.

State preemptions

UT-HB82-InternalADUapplies
Qualifying condition
Applies to all Utah cities of 1st-5th class (Tremonton is a 5th-class city, pop ~9,500 — between 1,000 and 10,000). Internal ADU mandate attaches within residential zones; Tremonton has RR-1 and R1-8/R1-10/R1-12/R1-20 single-family districts.
UT-SB174-SingleFamilyHousingModificationsapplies
Qualifying condition
Applies to all Utah cities; limits certain local restrictions on single-family housing (aesthetic/materials review). Tremonton RR-1 / R1-* residential standards are subject to these limits.
UT-HB406-DetachedADUapplies
Qualifying condition
Applies to Utah cities; extends HB 82 framework to allow detached ADUs in certain residential zones. Tremonton has multiple single-family districts (RR-1, R1-8 through R1-20) that would be within scope.
UT-LUDMA-Frameworkapplies
Qualifying condition
LUDMA governs all Utah municipal land use. Tremonton as a 5th-class city operates under LUDMA procedural framework.

Quirks & notes

  • Five-Tier Single-Family Lot-Size Ladder. RR-1 (43,560 sf) → R1-20 → R1-12 → R1-10 → R1-8 creates an explicit five-step density gradient encoded in district names (R1-N = N×1,000 sf minimum). This is finer-grained than most small Utah cities, reflecting Tremonton's agricultural-to-urban transition zones. Uniform 36 ft / 2.5-story height cap across all residential districts; density is modulated entirely via minimum lot area and setbacks, not height.
  • No Traditional Floodplain or Hazard Overlays in Chapter 1.16. Chapter 1.16 overlays are EXCLUSIVELY project/subdivision-specific (Spring Hollow Legends, Tremont Center, Aspen Grove RV, Edgewood, Aspen Ridges, Rivers Edge, 1000 North Corridor). Floodplain management is handled outside the zoning overlay framework — via FEMA NFIP compliance and a separate flood-damage-prevention ordinance referenced through Chapter 1.19 supplementary regulations rather than codified as an FP overlay district. This differs from Brigham City (same county), which does use FP/CC/HS hazard overlays.
  • Bear River Floodplain Constraint — Handled Via Separate Ordinance. Significant Bear River floodplain coverage on Tremonton's northern and western fringes triggers FEMA NFIP development review (elevation above BFE, compensatory storage) via the city's flood-damage-prevention ordinance — NOT via a codified Chapter 1.16 overlay zone. Bear River floodplain materially constrains residential and commercial development on northern and western parcels regardless of base district.
  • Agricultural-Use Overlay Absent — Agricultural-Use is Permitted-By-Right in Most Commercial/Industrial Zones. Chapter 1.08 Uses table lists 'Agriculture, Existing' as permitted-by-right in CD, CG, CH, CN, MD, MD-B, and MG districts. Tremonton does NOT use an AP-style agricultural preservation overlay to protect farmland at the city edge — instead, existing agriculture is grandfathered in all commercial/industrial zones, and rural character is preserved via the RR-1 district and large-lot R1-20.
  • Project-Specific Overlays Encode Development Agreements. Most Chapter 1.16 overlays (Spring Hollow Legends, Edgewood, Aspen Ridges, Rivers Edge) are tied to specific subdivision developments with required-amenity schedules and, in Rivers Edge's case, an explicit pre-annexation and master development agreement. Density up-zoning (6,000 sf lots vs. underlying R1-12's 12,000 sf) is traded for amenity infrastructure (clubhouse, trails, courts, fencing). This contract-zoning style is common in small Utah cities experiencing subdivision growth.
  • Two-Tier Commercial Height Split (75 ft vs. 35 ft). CD / CG / CH commercial districts permit 75 ft / 7 stories — unusually tall for a 9,500-population city, reflecting mixed-use ambition in the downtown core and highway corridors. CN (Neighborhood Commercial) is capped at 35 ft / 2 stories. This 40-foot height gap creates a sharp form transition between neighborhood-embedded CN and corridor/downtown CD/CG/CH.
  • Industrial Districts Have No Codified Maximum Height. MD, MD-B, and MG industrial districts defer maximum height to Conditional Use Permit process (marked 'C' in c§1.08.015). This gives the city discretionary control over tall industrial structures (grain elevators, silos, distribution-center racking) rather than a hard numerical cap. Combined with 100-foot loading-dock-facing-front setbacks, this makes Tremonton's industrial zones flexible for agricultural-industry and logistics uses that drive local economy (Malt-O-Meal / Post plant).
  • Tremont Center Overlay Enables Mixed-Use Without MU-Zone Lot Standards. TC-MU overlay defers nearly all dimensional controls to Site Plan review (Notes 3, 4, 5 in 1.16.040) rather than prescribing fixed lot / setback / FAR standards. This gives the city full discretion over Tremont Center development form — effectively a form-based-code-lite approach confined to a single overlay zone, while the rest of the city operates on traditional Euclidean dimensional tables.
  • Edgewood Overlay Subtracts Commercial Uses from Underlying MU. Edgewood Overlay is unusual: instead of ADDING uses to an underlying district, it subtracts — expressly prohibiting commercial uses permitted in the underlying Mixed Use (MU) district, leaving only residential typologies (single-family, twin home, attached) and narrow support uses (church, residential assisted-living C, ADU prohibited, residential facilities permitted). This creates a residential-only carve-out within an otherwise mixed-use district.
  • State Preemption Footprint is Light. As a 5th-class Utah city (pop ~9,500) outside any UTA fixed-guideway service area and of ambiguous MPO scope, Tremonton's state-preemption obligations are limited to HB 82 internal ADUs, HB 406 detached ADUs, SB 174 single-family modifications, and LUDMA procedural framework. HB 462 MIH applicability depends on WFRC MPO scope (adjacent county Box Elder is not a core WFRC member) — provisionally treated as not-applicable pending confirmation.

lot_coverage
Building footprint / lot area; not explicitly codified in Chapter 1.07 or 1.08 for Tremonton — derived inferentially from setback envelope and character.
far
Gross floor area / lot area; not explicitly codified in Tremonton's land use code — inferred from setback/height envelope for comparative purposes only.
du_ac
Dwelling units per acre. RM-8 = 8 du/ac maximum (attached housing); RM-16 = 16 du/ac maximum (attached housing) per c§1.07 RM district standards. SF districts du/ac derived from 43,560 / min_lot_sf.
setback_front
Minimum front-yard setback in feet per c§1.07.015 / c§1.08.015
setback_side
Minimum side-yard setback per side; most residential districts also specify a total-both-sides figure per c§1.07.015
setback_rear
Minimum rear-yard setback per c§1.07.015 / c§1.08.015
parking
Off-street parking per Chapter 1.17 of Title I — not specified per district in 1.07/1.08 dimensional tables; handled via separate chapter
