Demolitions and Major Residential Alterations and Additions

BDS has compiled the following information regarding demolition and major alterations and additions. Please use the links below to view information on City Code requirements.

Residential Demolition Inspection Requirements

As of February 10, 2020, new Interim Administrative Rules for the City of Portland Residential Building Demolition program are in effect.

New DEQ Regulations Require Residential Renovation Asbestos Survey

The Oregon Department of Environmental Quality adopted new asbestos regulations in fall 2018. DEQ now requires all houses and other residential buildings constructed prior to 2004 to have an asbestos survey conducted by an accredited inspector prior to demolition and renovation activities, with one exception. Owner-occupants doing their own home renovation work are exempt from this rule. This exemption does not apply when the residence is going to be demolished.

Changes to Requirements Around Residential Demolitions, Major Residential Alterations and Additions

Dust and site control measures are now required for demolitions of structures used for residential purposes with four or fewer dwelling units.

Additional Asbestos and Lead-Based Paint Information

The Oregon Department of Environmental Quality (DEQ) regulates renovations, repairs and removal of asbestos-containing materials. The Oregon Health Authority (OHA) provides information regarding lead-based paint and renovation, repair and painting.

How asbestos abatement and demolition affects Portland's sewer system

Asbestos abatement and structural demolition activities may discharge asbestos and lead paint particulates as well as other pollutants that are prohibited from entering the City stormwater system, but may be authorized to enter the sanitary sewer system.
