Time Period Building is Vacant | Requirement |
Within 1 year of vacancy | Install a Fire Department access box for annual fire inspection if the Fire Department determines it is necessary. Remove signage and sign structures |
Within 3 years of vacancy | City may require owner to paint the building a neutral color, if not already done |
Within 5 years of vacancy | City may require the removal of all hard surfaces, with the exception of the main driveway and fire lane around the building, restore the former hard-surfaced areas with black dirt and grass, or any combination of the above |
