Most homeowners don’t notice when electrical codes change — but those updates affect how safe, efficient, and compliant your home’s wiring is. In Utah, electrical code revisions are adopted regularly, and they can impact everything from where outlets are placed to how breakers are installed.
For homeowners in Lehi and throughout Utah County, understanding these changes can prevent surprise costs during renovations or inspections. In this blog, we’ll explain the most important updates and what they mean for your home.
Electrical codes are rules that guide safe installation of wiring, panels, outlets, and other components. These rules are updated every three years at the national level through the National Electrical Code (NEC). Utah adopts a version of the NEC and occasionally adds its own amendments to reflect local needs.
When Utah adopts a new code cycle, contractors, builders, and electricians must follow the updated requirements for all new construction and major remodels. Even small upgrades, like adding a circuit or rewiring a basement, may trigger compliance with certain sections of the new code.
While there are many small updates, here are the most important ones homeowners should know about.
Utah now follows the 2021 International Residential Code (IRC), which includes several building and electrical provisions that impact new construction and remodels.
Ground Fault Circuit Interrupter (GFCI) protection is now required in more areas, including basements, garages, and certain outdoor locations. The wording has been updated to clarify when unfinished spaces need protection.
Kitchen remodels must now provide receptacles in certain locations on countertops, islands, and peninsulas — or at least leave space and wiring provisions for future outlets.
Your home’s main disconnect switches are now limited to a maximum of six, all grouped in one location. This matters if you have multiple panels or subpanels that need to be consolidated.
Any outlet box used to mount a ceiling fan must be rated specifically for that purpose and able to support the weight and movement of the fan.
Changes were made to how certain cables must be bent when routed through studs, joists, or tight spaces. This affects how wiring is installed during remodels and may require extra planning to maintain compliance.
These code updates are not just technical—they affect real projects. Here’s how they may apply in your home:
Kitchen Remodels – You may need to add or relocate outlets on islands and countertops.
Basement Finishing – Circuits may require GFCI protection depending on whether the space is finished.
Panel Upgrades – Multiple panels or disconnects may need to be grouped or reduced.
Ceiling Fan Installations – Boxes must be rated to support the fan safely.
Rewiring Projects – Cable routing and bend radius must meet updated specifications.
Understanding these rules before work starts prevents failed inspections, added costs, and project delays.
If you are planning electrical work in your home, here’s how to prepare:
A local Lehi electrician will be familiar with Utah’s specific code amendments and ensure your project passes inspection the first time.
Before starting a remodel or panel upgrade, ask your electrician to review the project for code requirements.
Older homes may not meet today’s standards. Use remodels as an opportunity to bring wiring and panels up to date for safety.
If codes require you to leave space or provisions for future outlets or circuits, plan ahead for possible EV chargers, solar systems, or additions.
Proper permitting ensures work is safe and that your home remains insurable and marketable when you sell.
They apply to new construction and to any remodel or upgrade that modifies wiring or adds new circuits. Existing systems are usually grandfathered unless altered.
No. You only need to bring parts of your home up to code when you modify them. However, it may be smart to upgrade old wiring if walls are open.
Non-compliant work can fail inspection, delay your project, and even create safety hazards. It may also affect insurance coverage.
Sometimes. Extra outlets, GFCI devices, and proper-rated boxes can add cost. But they also improve safety and reduce future risk.
A licensed electrician can review your plans and explain which sections of the code will affect your work.
Utah’s adoption of the 2021 residential and electrical code, along with updates to GFCI protection, receptacle placement, disconnect requirements, and wiring rules, will affect how many homeowners approach remodels and upgrades. Staying ahead of these changes helps avoid surprises and keeps your home safe and compliant.
