Solar site surveys · UtahA technician on the roof, in the attic and at the service panel, with the survey read against the code editions, AHJs and utilities that apply in Utah.
Utah's Legislature adopts the State Construction Code by statute: as of July 1, 2026 it pairs the 2021 IRC with the 2023 NEC and the 2024 IBC, and the State Fire Code is the 2024 IFC. Rocky Mountain Power's Schedule 137 net billing credits exports at an avoided-cost rate reset each March. Surveys along the Wasatch Front must account for Utah's own ground snow load table, high seismic design categories and downslope wind events.
The capture spec is the same everywhere. What the engineer and the plan reviewer read it against is not.
Utah replaces the IRC snow map with its own table and the Utah Snow Load Study. Salt Lake City is listed at 28 psf at 4,239 feet, while mountain towns such as Heber City (60 psf) and Coalville (57 psf) are far higher.4
The Wasatch fault runs along the populated Front. The state's worst-case planning scenario is a magnitude 7.0 quake on its Salt Lake City segment, and the March 2020 M5.7 Magna earthquake damaged buildings and homes in the valley.6,7
Easterly downslope wind events can drive damaging gusts into Wasatch Front valleys, as in September 2020, when widespread damage and outages hit northern Utah. Check attachment spacing against the local design wind speed.8,9
HOA rules alone cannot ban solar on detached homes, but associations can impose reasonable conditions, such as not extending above the roof line or matching frame colors to the roof. Record any HOA condition at the survey.10
Who reviews the plan set, and what the state layers on top.
Rocky Mountain Power is regulated by the Utah Public Service Commission, which approves its Schedule 137 export credit rate each year. Earlier Schedules 135 (net metering) and 136 (transition) are closed to new applicants.12,13
Installers apply online with a photo of the meter and wait for approval, then permit, install and upload the passed inspection before RMP sets the meter (about 7 to 10 days) and authorizes the system to be turned on. Inverters must use RMP's required settings, and 5-jaw meter-mounted adapters are not permitted.13
Interconnection page ↗One standard, one visit, the same record in Utah as everywhere else. What it gets checked against is the code stack above.
The 2023 NEC. The Legislature adopts it by statute in Utah Code 15A-2-103, and it has been in force statewide since July 1, 2025.1,2
New customers are on Schedule 137 net billing. Since March 1, 2026, exports earn 4.855 cents/kWh from June to September and 4.033 cents/kWh from October to May, and the rate is reset each year.12
Not through its rules for lots with detached homes; only the declaration can restrict it, and adding a ban requires a vote of at least 67% of voting interests. HOAs can still set conditions such as keeping panels below the roof line.10
Use Utah's own snow load table and the Utah Snow Load Study rather than the IRC map. Salt Lake City is 28 psf, but mountain towns such as Heber City reach 60 psf.4
RMP publishes a typical step-by-step timeline and notes that some projects take longer than 70 business days, especially if its equipment needs upgrades. After the passed inspection is uploaded, meter installation takes about 7 to 10 days.13
