Change of Use / Change of Occupancy in Lyons, Colorado

The Town of Lyons publishes a dedicated 'Change in Use/Occupancy (No Work) Permit' for when a new business is preparing to move into an existing building/tenant space, NO work requiring a permit is being done to that space, and the occupancy type remains the same — a directly-confirmed, named permit category distinct from the general Building Permit process.

Tips

  • Lyons' 'Change in Use/Occupancy (No Work) Permit' is specifically for a same-occupancy-type tenant swap with zero permit-triggering construction — if your new business involves ANY work requiring a permit, or an actual change in occupancy classification, you'll need the standard Building Permit process instead.
