Farmington updating building codes; 90-day review starts June 20, 2026

Farmington is updating the building codes it references for construction permits, switching from its current ICC and NEC editions to newer versions. The city has opened a 90-day inspection and written-comment period starting June 20, 2026, before City Council considers adoption by ordinance.

In its announcement, the City of Farmington says it is currently operating under the 2015 International Code Council (ICC) family and the 2014 National Electrical Code (NEC), which were adopted in 2018. The update would replace those references with the most current code cycle.

What Farmington is considering adopting

The city’s proposed adoption by ordinance includes multiple updated ICC codes and a newer NEC edition. Farmington lists the following codes for consideration:

• 2024 International Building Code
• 2024 International Residential Code
• 2024 International Plumbing Code
• 2024 International Mechanical Code
• 2024 International Fuel Gas Code
• 2024 International Energy Conservation Code
• 2024 International Existing Building Code
• 2024 International Property Maintenance Code
• 2024 International Swimming Pool and Spa Code
• 2024 International Private Sewage Disposal Code
• 2024 International Fire Code
• 2023 National Electrical Code (NFPA 70)

Farmington notes that ICC updates are released every three years, but the city does not adopt every cycle. The city links that approach to adoption costs including staff time, legal review, and reference-material updates—plus the time it takes builders and design professionals to become familiar with new requirements.

The 90-day review and comment window (starting June 20)

Farmington says residents can review the updated code materials for ninety days. During that inspection-availability timeframe—and before final adoption—residents may inspect the materials or submit written comments to the City Clerk.

The city also says no public hearing is required; the key step is the inspection-availability period. The period begins June 20, 2026. Copies of the codes, along with the proposed adopting ordinance with local amendments, are on display for public review at the City Clerk’s office at Long Memorial Hall, 110 West Columbia Street in Farmington.

Why this can matter for remodeling, additions, and new construction

The city says the updated codes cover the full range of construction, from structural, plumbing, mechanical, and electrical systems to fire safety—for both new construction and major renovations. That means the specific code edition that applies to a project can affect how permit applications are reviewed and what builders design to.

Farmington also says its Building Code Advisory Board—which includes local contractors and a local architect—reviewed the updated codes and proposed local amendments before recommending adoption to City Council.

If you’re planning ahead, the practical takeaway is to check what’s proposed now—before you finalize plans and apply for permits. Farmington’s published building permit fees may also be relevant as you move from design to permitting, and the city’s permit fee schedule is listed as subject to change.

Where to verify what’s current

Farmington directs residents to its Codes and Ordinances page for the official/current workflow. That page notes that codes and ordinances shown online may not be the most recent, and that the most current edition is available in City Hall. If what you see online doesn’t match what you’re planning—or if you have questions about the update process—Farmington says to contact the City Clerk.
