Demolition Permit: A permit issued by a local building department authorizing the demolition of a structure or significant portion of a structure, typically requiring documentation of utility disconnections, asbestos and lead abatement, and disposal plans.
When a Demolition Permit Is Required
Demolition permits are required for tearing down an entire structure (house, garage, shed above a certain size), removing a major structural element (load-bearing wall, chimney, foundation section), and in many cities, selective interior demolition beyond a certain scope. Minor interior demolition — removing non-structural walls during a remodel — is typically covered by the building permit for the remodel rather than requiring a separate demo permit.
Pre-Demolition Requirements
Before a demolition permit is issued, most jurisdictions require: disconnection of all utilities (gas, electric, water, sewer) with documentation from the utility companies, an asbestos survey for buildings built before 1980, asbestos abatement if asbestos-containing materials are present (required by EPA regulations), a lead paint survey for buildings built before 1978, and sometimes a structural pest inspection. These requirements exist to protect workers and the surrounding environment.
Historic Preservation Restrictions
In many cities, demolition permits for older buildings trigger historic preservation review. Buildings on local, state, or national historic registers may require approval from the historic preservation commission before demolition is permitted. Even buildings not formally designated may be subject to pre-demolition review if they fall within a historic district. This review can add months to the process.
Debris Disposal Requirements
Many jurisdictions require documentation of where demolition debris will be disposed. Some require a recycling or waste diversion plan to meet local sustainability requirements. Concrete, wood, metal, and other materials may need to be sorted and disposed of separately. Check your city's demolition permit requirements for specific debris management rules.
