How Remodeling Permits Differ Between Vancouver, WA and Portland
Two states, two codes, two calendars
Oregon projects are reviewed under the Oregon Residential Specialty Code. Washington projects are reviewed under the Washington State Residential Code, with the Washington State Energy Code layered on top.
The energy code is the difference homeowners feel first. Washington's residential energy provisions are among the strictest in the country and use a credit system: a project has to earn energy credits through measures such as high-efficiency heat pumps, heat pump water heaters, improved envelope air sealing or upgraded windows.
That shapes mechanical selection on a Vancouver or Camas remodel in a way it does not on a Portland one. It is not a surprise cost if it is designed in from the start, and it is an expensive surprise if it is not.
Jurisdictionally, Portland work goes through Portland BDS. Vancouver work goes through the City of Vancouver, and anything outside city limits — Felida, Salmon Creek, much of Ridgefield — goes through Clark County.
Review timelines
Trade permits behave similarly on both sides. Electrical, plumbing and mechanical permits for work inside an existing footprint are typically issued quickly, sometimes over the counter or online.
Structural review is where the two systems diverge. Portland BDS handles a very high volume of residential permits, and plan review on an addition or a structural remodel can sit in queue for months during busy periods. Historic and design-overlay reviews add their own cycles.
Vancouver and Clark County generally move a comparable residential addition through review faster, though volume and staffing swing both. Clark County work outside the urban growth boundary can add septic and well review, which adds time back.
Neither timeline is something we guess at. We confirm the current queue with the jurisdiction before we publish a schedule.
Fees and what drives them
Both sides calculate building permit fees from project valuation, plus plan review as a percentage, plus separate trade permits. The structure is similar; the add-ons are not.
Portland layers system development charges on projects that add plumbing fixtures or dwelling units, and those charges can be substantial on an addition or an ADU. Portland has at times waived or reduced certain ADU charges, and those programs change — we verify the current rule at the time you permit rather than quoting last year's.
Vancouver and Clark County apply impact fees for traffic, parks and schools on projects that add a dwelling unit. On a straight remodel or an interior reconfiguration, neither side triggers much beyond the permit itself.
We put the actual, verified fee figures into your budget before you sign, rather than carrying them as an allowance.
ADU rules are the biggest single difference
Portland is unusually permissive. City code allows accessory dwelling units broadly on residential lots, and recent state and city changes have gone further on unit counts and parking.
Washington has moved in the same direction under state law requiring cities to allow accessory units in urban growth areas, but the local implementation in Vancouver and Clark County carries its own size caps, setback rules, owner-occupancy history and parking treatment.
The practical effect: a detached ADU that is straightforward in Southeast Portland may need a different footprint, height or siting in Felida or Salmon Creek to clear local standards.
Our ADU cost guide for Portland and Vancouver covers both sides, and our ADU builder service explains how we run these projects.
What we handle
Permitting is inside our contract, not billed as an extra when the drawings are done. We prepare the permit set, coordinate the structural engineer, submit the application, respond to plan review corrections and schedule every inspection.
That includes the parts homeowners rarely see: energy code compliance paperwork on the Washington side, deferred submittals for engineered products, and revisions when a field condition forces a change to an approved drawing.
Being licensed in both states — Oregon CCB #248237 and Washington — means a Camas or Washougal project runs the same way a Portland one does, with the same project lead and the same written weekly update.
