Building Code
Oregon Structural Specialty Code (OSSC), 2022 edition
Oregon · Licensed Professional Engineering
Site engineering that clears local review — grading, drainage, and utilities designed to each jurisdiction's published standards from day one.
Civil and site engineering in Oregon is defined by stormwater. West of the Cascades, heavy rainfall combined with some of the strictest on-site management rules in the country — Portland's infiltration and green-infrastructure requirements in particular — mean bioretention, vegetated facilities, and infiltration testing shape site layout from the outset. We design stormwater treatment and flow-control facilities, grading, utility connections, and ADA-compliant paving to each jurisdiction's standards and to Oregon's construction stormwater permit. Land-use planning under Oregon's statewide goals and urban growth boundaries adds an entitlement layer unfamiliar to many out-of-state developers. East of the Cascades, the high-desert hydrology and drywell-based drainage in the Bend area change the approach entirely, so we tailor stormwater strategy to the specific regional conditions rather than applying a single template.
Code adoptions change on multi-year cycles and many states allow local amendments. The researched source verification date is 2026-07-28; we verify the governing edition with your permitting jurisdiction at project kickoff.
Oregon's uniform statewide code makes plan review consistent across jurisdictions, though metro Portland and Washington County (Hillsboro's Silicon Forest) run high-volume review. Stormwater is a defining permitting issue — Portland's on-site infiltration and green-infrastructure requirements are among the strictest in the country — and Cascadia seismic detailing is expected on essential facilities.
Oregon licenses PEs by comity for qualified out-of-state applicants and accepts electronic seals; the state applies specific rules on seal and signature requirements for digital submittals.
Oregon's construction market is anchored by the semiconductor and high-tech cluster in Washington County (Intel and the Silicon Forest), data centers in the Columbia River corridor near The Dalles and Hermiston, and steady Portland-metro commercial and institutional work. Fast-growing Bend adds high-desert development, and mass-timber construction is a notable regional strength.
Key markets: Portland, Salem, Eugene, Gresham, Hillsboro, Bend.
