Building Permit
A building permit is official authorization from the local building department allowing specific construction work to proceed in compliance with building codes and zoning regulations.
Building permits ensure construction work meets safety codes and zoning requirements. Denver requires permits for structural work, additions, new construction, major remodels, plumbing, electrical, and mechanical systems. The permit process includes submitting plans, paying fees, and receiving approval before starting work. Inspections occur at specific stages: foundation, framing, rough-in, insulation, and final. Working without permits risks fines, work stoppage, and complications when selling your home—unpermitted work must be disclosed and often requires retroactive permitting.
What Requires a Permit in Denver
Structural changes, additions, new construction, plumbing, electrical, and mechanical work require permits. Finishing basements, removing walls, adding bathrooms, replacing windows, and re-roofing all need permits. Minor work typically doesn't: painting, flooring, cabinets (without plumbing changes), and cosmetic updates. When unsure, call Denver Development Services—working without required permits creates liability. Permit costs vary by project scope: simple electrical permits may cost $100-200, while major remodel permits can reach $2,000-5,000.

Occupancy Permit
An occupancy permit (certificate of occupancy) is official documentation from the building department certifying that construction is complete, inspections passed, and the building is safe for occupancy.
