Del Norte County, CA Noise Ordinances: Construction Hours (2026)

In the unincorporated area of Del Norte County, construction noise is addressed as an exemption inside the county's noise ordinance rather than a separate building-hours code. The ordinance text (proposed for Title 7, Chapter 7 of the County Code) lists as exempt 'Noise sources associated with construction, repair, remodeling, or grading of any real property, provided said activities do not take place between the hours of 8:00 p.m. and 7:00 a.m. on weekdays, including Saturday, or at any time on Sunday or a Federal holiday.' In plain terms, ordinary daytime construction noise is permitted, but work outside the 7:00 a.m. to 8:00 p.m. weekday/Saturday window, or any work on a Sunday or federal holiday, loses the exemption and can be cited under the noise standards or the county nuisance ordinance. 'Grading' is defined as excavating or filling earth to prepare a site for construction. These rules cover unincorporated communities such as Klamath, Gasquet, Smith River, and Fort Dick. Because this is a county exemption, it applies to property in the unincorporated area; Crescent City sets its own construction-hour rules. Always confirm current adopted language and any permit conditions with Del Norte County Community Development before relying on a specific window.
