New requirements relating to the moisture protection of multi-unit residential buildings containing more than two units were approved in the recent session of the Washington State Legislature. Engrossed House Bill 1848 (EHB-1848) requires several new actions by design professionals and qualified inspectors.

These requirements go into effect Aug. 1, 2005, and will apply to building permits issued on or after that date. The new law requires that:

• the plans, details and specifications for the construction of the building enclosure of new multi-unit residential buildings with more than two units, and most multi-unit residential buildings being rehabilitated, be stamped by a licensed engineer or architect
• the design professional of record submit a statement affirming that the building enclosure documents satisfy the requirements of EHB-1848
• DPD not issue the building permit without those design documents and statement being on file
• a third-party, qualified inspector inspect the building enclosure during the course of construction for compliance with the building enclosure design documents
• the third-party inspector submit a signed letter of certification to DPD regarding the inspection and substantial compliance of the building with the building enclosure design documents
• DPD not issue a certificate of occupancy or equivalent prior to receiving the inspector’s certification

Please note that DPD staff will not:

• review the building enclosure details for adequacy
• review the qualifications of the third-party building enclosure inspector
• review the inspection record of the building enclosure construction
