What the Oregon permit process involves
Wherever you are in Oregon, the mezzanine permit package looks the same: PE-stamped structural drawings with load calculations, slab adequacy analysis, and connection details, submitted to the authority above. Permit fees typically run 1–3% of construction value, plan review typically takes 6–14 weeks, and the full kickoff-to-occupancy cycle runs 10–16 weeks — the sources behind those figures are in our full permit guide. The plan reviewer checks your drawings against the code above — including the one-third rule and 7-foot clear heights and, where triggered, sprinkler requirements below the deck.
