Deconstruction Requirements

On July 6, 2016, Portland City Council adopted an ordinance, including code language, which requires certain projects seeking a demolition permit to be fully deconstructed as opposed to mechanically demolished. With Council’s unanimous approval of that ordinance, Portland became the first city in the country to ensure that valuable materials are salvaged for reuse instead of crushed and landfilled. The ordinance became effective on Oct. 31, 2016.

All single-dwelling structures (houses and duplexes) in all zones are subject to the Deconstruction Ordinance if:

  • The structure was built in 1916 or earlier; or
  • The structure is designated as a historic resource subject to the demolition review or 120-day delay provisions of Title 33.

A Certified Deconstruction Contractor must perform the deconstruction work. Certified Deconstruction Contractors are trained to safely and effectively disassemble the house and salvage valuable materials for reuse. Once you have selected a deconstruction contractor for your project, they will need to submit a Pre-Deconstruction Form before your demolition permit can be issued. Only certified contractors have access to the Pre-Deconstruction Form.
