Building Permit — valuation $25,001 to $50,000DRIFT FIX 2026-07-23: St. George's two live official fee PDFs disagree on this single tier. The Building Fee Sheet (sgcityutah.gov, PDF created 2020-08-13) prints '$391.75 for the first $25,000.00 plus $10.10...' both in its table and its prose, but its own table is internally inconsistent at this exact boundary — $24,000 is priced at $377.25 and $25,000 at $391.75, a $14.50 jump vs. the stated $14.00-per-$1,000 rate used everywhere else in the same table. The St. George City Impact Fees document (effective 4/21/21, chronologically newer) prints '$391.25 for the first $25,000.00 plus $10.10...' for the identical tier, which is arithmetically consistent ($69.25 + 23 x $14.00 = $391.25) and matches the $69.25-at-$2,000 and $643.75-at-$50,000 anchor points shared by both documents. Adopting the Impact Fees figure ($391.25) as the better-grounded value; both source PDFs directly re-fetched and confirmed live 2026-07-23.
