Glenn County, CA Building Safety: Building Permits (2026)

Glenn County's building department, run by the building official, enforces Title 15 and the incorporated construction codes in unincorporated Glenn County (Section 15.11.010). Section 15.11.030 requires anyone who wants to erect, construct, reconstruct, move, enlarge, convert, alter, repair or demolish an apartment, house, manufactured or mobilehome on a foundation, hotel, dwelling or other building to file an application with the building department. The application must name the property owner and contractor, list their residence and business mailing addresses, give the legal description and street address of the property, describe the kind of building and its purpose, state the number of stories and square footage, estimate the cost of the work, and include any plans, diagrams, computations or specifications the building official requires.

Applications must also include the contractor's certificate required by Labor Code Section 3800 (Section 15.11.050) and be accompanied by permit fees set by the Board of Supervisors (Section 15.11.060). Certain projects, such as those adding a driveway approach or converting between residential, commercial, industrial or agricultural use, trigger frontage improvement requirements before final inspection (Section 15.11.070). A permit expires and becomes void if work is not started within 180 days of issuance, or if work is abandoned or suspended for 180 days; the chief building official may grant one 180-day extension in writing on a showing of justifiable cause (Section 15.11.090).
