Full Breakdown
without limiting the intended function of fences and walls' (subsection A), then requires a permit before anything gets built. 120, the code's general permit-review section: the applicant submits building-permit materials to the planning and development services department, and the chief building official issues the permit once the application complies with code requirements, all applicable land-use approvals such as an approved plat or site plan, and, for construction in a floodplain, the floodplain development-permit rules in Title 20. B. b. The permit requirement applies citywide inside Longmont; homeowners in the small part of the city that sits in Weld County still apply through the city, not the county, because it is city zoning that governs.
Violations & Fines
Building without the required permit is a development-code violation under § 15.09.030, and § 15.09.040 treats each day the unpermitted fence stands as a separate offense. Under § 15.09.050 the city can withhold or deny the permit outright, revoke or suspend a permit already issued, issue a stop-work order on the construction, and go to court for an injunction requiring the fence's removal or modification.
