Where in Portland: the Central Eastside Industrial District, the Lloyd District and the Swan Island industrial peninsula.
Typical buildings: converted warehouse buildings turned office and flex space on the Eastside, mid-rise office towers in the Lloyd District, and heavy industrial and marine-terminal buildings on Swan Island.
Permitting: Portland runs its own program: the City of Portland Bureau of Development Services (BDS) reviews and inspects both the building and the electrical permit inside city limits, rather than deferring to a county.
