Williston Zoning Overview

Williston is located in Williams County, North Dakota, with a population of 29,160 (2020 Census). A major hub of the Bakken oil region, Williston has experienced significant growth and manages land use and development through its zoning ordinance, which is administered by the Williston Planning Department. The zoning code divides the city into residential, commercial, and industrial districts, each with specific dimensional standards governing lot size, building height, setbacks, and density.

Building Code

Williston follows the ND State Building Code, which is based on the International Building Code (IBC) and the International Residential Code (IRC). All construction, renovation, and demolition projects must comply with this code. Contact the Williston Planning Department at (701) 577-8100 for information about any local amendments or additional requirements.

ADU (Accessory Dwelling Unit) Rules

ADU regulations for Williston have not been confirmed. North Dakota does not have a state-level law mandating that cities allow accessory dwelling units. Property owners interested in building an ADU should contact the Williston Planning Department to determine whether ADUs are permitted in their zoning district and what standards apply.

Development Process

Development in Williston requires obtaining the appropriate permits from the Planning Department. The process typically involves:

  1. Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
  2. Site Plan Review — For commercial and multi-family projects, submit a site plan for review
  3. Building Permit Application — Apply for a building permit with construction documents
  4. Inspections — Schedule required inspections during construction
  5. Certificate of Occupancy — Obtain final approval before occupying the structure

For projects that do not conform to existing zoning, property owners may need to seek a variance, conditional use permit (CUP), or rezoning through the Board of Adjustment or Planning and Zoning Commission.

Key Considerations

Before starting any development project in Williston, property owners should:

  • Verify the zoning classification of their property through the Planning Department or the municipal code
  • Review setback, height, and lot coverage requirements for the applicable district
  • Check for any overlay districts or special regulations
  • Determine if the property is in a flood zone using FEMA's flood map service
  • Confirm whether HOA covenants or deed restrictions apply
  • Contact the Planning Department at (701) 577-8100 for pre-application guidance
