Denver, CO Code Violation Reporting: Common Violations (2026)

The most frequently reported code violations in Denver include: weeds and overgrown vegetation exceeding 6 inches (Denver Revised Municipal Code Section 49-246), junk and debris accumulation on residential property, abandoned or inoperable vehicles, parking on unpaved surfaces in residential areas, graffiti, unpermitted construction or remodeling, fence violations, and signage violations. Denver is particularly strict about weed control during growing season (May through October), when city inspectors actively patrol neighborhoods. The city's Neighborhood Inspection Services (NIS) division handles most property maintenance complaints. Building code violations are handled by Community Planning and Development. Denver also enforces snow removal requirements, requiring property owners to clear sidewalks within 24 hours after snowfall. Trash and recycling container storage violations are common, as containers must be stored out of public view except on collection days. The city maintains an online portal for checking violation status.
