Full Breakdown
Section 10-13-24 of the Washington County Code sets a single, zone-blind construction schedule that applies to all construction sites regardless of zone, covering the unincorporated county from St. George's outskirts to the Zion gateway communities. m. , cutting four hours off the evening end. The ordinance then adds a standing rest-day rule: no work shifts are allowed on Sundays or legal county holidays unless the Public Works Department, or its designee, has given prior written approval for that specific day or time. That approval requirement is site- and date-specific, so a blanket weekday permit does not extend to a Sunday pour or a holiday grading shift without a separate written sign-off.
The section was amended by Ordinance 2025-1292-O on May 6, 2025, replacing an earlier version adopted under Ordinance 2022-1205-O on March 15, 2022, and it sits in the same Title 10, Chapter 13 group as the county's Short Term Rental noise and events rules, reflecting the county's broader effort to manage construction and rental noise together as residential growth spreads across unincorporated Washington County.

Construction outside the permitted hours, or on a Sunday or county holiday without the Public Works Department's prior written approval, is a violation of Title 10 enforced under § 10-1-12 by the county's building inspector and public works director.
