Overview

GridPermit collects Utah residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Permit timeline

28–56 days

Search-derived reporting (not the City's own page directly) cited a 4-8 week standard review timeline for residential projects; the City's own Solar PV Systems page states the permit becomes null and void if work is not commenced within 180 days of issuance, or if work is suspended/abandoned for 180 days, but does not itself state a review-turnaround day-count.

Interconnection

https://commerce.utah.gov/ocs/rooftop-solar/

Utah's rooftop-solar customer classification is governed by a settlement agreement and Utah Public Service Commission order, summarized on the Utah Department of Commerce Office of Consumer Services' own page: customers fall into one of three tiers based on when their complete interconnection application was submitted to Rocky Mountain Power — Net-Metered (NEM) if before 2017-11-15, Transition if 2017-11-15 through 2020-10-30, and Post-Transition/Export Credit if after 2020-10-30 (the tier all new applicants fall under today). The exact current Schedule 137 Export Credit Rate dollar/cents-per-kWh figure was not independently confirmed from a primary Utah PSC tariff filing this session (a specific PSC document URL located via search returned HTTP 404) — left unrecorded rather than using a third-party-reported figure.

Confidence: High (0.85)

Permit authority

Salt Lake City Building Services

Utah has no single statewide residential solar permitting portal — permitting authority sits with the local municipality (inside its boundaries) or the county (in unincorporated areas). Salt Lake City's own Building Services division is the permitting authority within city limits.
