Fee schedule

Demolition PermitGrounded/verified: Washington County Community Development Fees page (washco.utah.gov/departments/community-development/fees/, fetched 2026-07-01) does not publish a separate flat demolition fee — confirmed by direct fetch and a Wayback Machine snapshot ('demoli' does not appear in any published fee schedule). Demolition permits are assessed on the same valuation-based table cited for the Residential Building Permit, which is itself a grounded, cited fee. This is a fully grounded valuation-based fee, not an estimate. lastVerified 2026-07-01.

This entry previously described the 2024-cycle codes in future tense ('effective through June 30, 2026' / 'takes effect July 1, 2026'); that date has now passed, so IBC/IPC/IMC/IFGC/IECC/IEBC/residential ISPSC are now stated as CURRENT (2024 editions), while IRC (2021) and NEC (2023) remain unchanged as already correctly stated. No Washington County page listing IBC/IRC/IPC/IMC/IECC editions specifically was found on live re-check of the Community Development FAQ and Building Permit Documents pages (2026-07-16), so there is no city-page lag to record for those codes beyond the pre-existing NEC observation above..
