How Does Plan Review Work at Portland's Bureau of Development Services?

By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15

Portland BDS runs plan review through Development Hub PDX for applications and ProjectDox for electronic drawing review, with structural, life-safety, energy, accessibility, and zoning reviewers working in parallel. Structural submittals need stamped calculations and geotechnical reports where required, and permits issue only after every review group approves. Sites outside city limits follow the county's separate process.

The Electronic Submittal Path

The modern Portland submittal never touches paper. The applicant creates the project in Development Hub PDX, uploads the drawing set and supporting documents, and pays fees online. ProjectDox becomes the shared workspace where BDS reviewers and partner bureaus mark up the same files, and corrections come back as consolidated review comments the design team answers with revised sheets uploaded to the same system. The electronic workflow eliminates the old ritual of driving plan sets to the permit center, and it creates a complete record of every comment and response. A clean first submittal is the fastest path through review. Reviewers see hundreds of projects, and the sets that move are the ones where the structural calculations reference the drawings sheet by sheet, the code analysis matches the occupancy and construction type, and the zoning diagrams answer the planner's questions before they are asked. Incomplete submittals stall in intake or draw correction cycles that each add weeks. The bureau publishes checklists and handouts for common project types, and the experienced applicant treats them as the minimum rather than the goal.

Structural Review in a Cascadia City

The structural reviewer reads the calculations the way a proofreader reads a manuscript: every load needs a source, every member needs a demand-capacity check, and the load path needs to be continuous from roof to foundation. Seismic design gets the closest reading, because Portland's design earthquake is dominated by the Cascadia subduction zone's long-duration, long-period shaking. The reviewer checks that the lateral system is complete and properly detailed, that diaphragms and collectors deliver forces to the vertical elements, and that foundations address the geotechnical report's liquefaction and lateral-spread findings. Nonstructural components get their own scrutiny. Equipment anchorage, cladding connections, and ceiling systems must be designed for the seismic forces the code assigns, with the calculations and details in the permit set rather than deferred to the field. Special inspection requirements are established at permit issuance, covering structural steel, concrete, masonry, and soils work as applicable. When the reviewer issues corrections, the engineer answers each one directly with revised calculations or details, because an unanswered comment returns in the next cycle.

What else do project teams ask?

What is Development Hub PDX?
Development Hub PDX is the City of Portland's online permitting portal, available around the clock for submitting most building permit applications, paying fees, and tracking review status. It replaced much of the in-person permit counter workflow. Applicants who need help using it can visit the Development Services Center, where staff assist with uploads and scheduling.
What is ProjectDox?
ProjectDox is the electronic plan review system BDS uses to review drawings and documents online. Applicants upload their plan sets, and city reviewers across bureaus mark up and comment on the same files simultaneously. Corrections and resubmittals happen in the system, so the entire review history lives in one place instead of in stacks of paper plan sets.
Do I need an engineer for a Portland building permit?
Commercial, multifamily, and most structural work requires drawings and calculations stamped by a licensed design professional. Even residential projects need engineering where the work exceeds prescriptive code limits, involves retaining walls, sits on steep slopes, or falls in a hazard area. The BDS checklists identify when stamped calculations are required for common project types.
How does Portland's seismic setting affect plan review?
Portland's design earthquake is shaped by the Cascadia subduction zone, which produces long-duration shaking that is especially demanding for taller and flexible structures. Structural reviewers expect complete lateral systems, proper seismic detailing, nonstructural anchorage, and geotechnical reports that address liquefaction and lateral spread near the rivers. The seismic design cannot be an afterthought in the submittal.
What if my site is outside Portland city limits?
Then BDS is not the AHJ. Unincorporated areas of Multnomah, Washington, and Clackamas counties run their own building and land-use programs with separate portals, checklists, fees, and timelines. Because annexation boundaries are irregular, the design team verifies the jurisdiction from the parcel address before preparing the submittal, since a set prepared for Portland's amendments will draw corrections under the county's process.
