Deconstruction Ordinance Expansion


November 19, 2019

Deconstruction Ordinance Expansion

Portland’s existing deconstruction ordinance is expanding. Effective on and after January 20, 2020 permit applications for demolition of a house or duplex built in 1940 or earlier will be required to deconstruct using a Certified Deconstruction Contractor. Since October of 2016 the deconstruction ordinance has applied to houses and duplexes built in 1916 or earlier (or designated historic regardless of age). Only the year-built threshold changes on January 20th. Houses and duplexes designated as a historic resource, even if built after 1940, will continue to require deconstruction. A copy of the adopted code can be found here.
