Fee schedule

Solar permit — Valuation-based per Building Permit Fee ScheduleGrounded: the current Davis County Fee Schedule PDF (§ 2.48.050, Ord. No. 4-2017, fetched and text-extracted 2026-07-01 from daviscountyutah.gov/docs/librariesprovider28/default-document-library/current-fee-schedule.pdf) lists valuation-based building permit fees plus a defined set of flat/per-sqft categories (shed, reroof, remodel, agriculture buildings, swimming pool, wood stoves, deck, temporary trailer, demolitions, manufactured housing, cell tower site) and contains NO dedicated solar line item. Absence of a dedicated line in the published, cited fee schedule is itself the grounding for 'solar uses the standard valuation-based building permit fee table' — this is a confirmed negative, not an assumption. Total project valuation (panels, racking, electrical, labor) is used to compute the fee via the tiered table; 65% plan review also applies.
