Hiring the designer is the moment the project starts feeling real, and it's the highest-leverage decision you'll make. A designer who has finished several Portland pop-ups has muscle memory for what PP&D reviewers ask for and what older Portland houses actually hide — that's most of what you're paying for.
Architect vs. residential designer
For most Portland additions, you have a real choice:
- Licensed architect (Oregon Board of Architect Examiners). Required for projects above certain occupancy thresholds; rarely required for single-family additions, but many architects work in this segment. Higher fee, broader scope, fuller construction administration.
- Residential designer. Not licensed as architects but typically CCB-registered as residential design contractors. Most Portland addition projects use this path. Lower fee, narrower scope. Best ones have produced dozens of permitted additions and know PP&D reviewers by name.
For a project in a Historic District or Conservation District, lean toward an architect with HD/CD experience — the design-review process rewards experienced submitters.
What you're hiring
A designer's scope on a Portland addition typically covers:
- Schematic design — preliminary plans, elevations, massing.
- Design development — refined plans, sections, exterior materials, basic specifications.
- Construction documents — the full permit-set drawings.
- PP&D submittal — application, response to corrections.
- Construction administration (optional) — periodic site visits, response to GC questions, change-order review.
Pick the scope. Construction administration is worth it on additions; cutting it to save 10% on design fees is a false economy when the GC has a question every other week.
Fee structures
Three common structures:
- Percentage of construction cost — 10–15% for design only, 12–18% with construction administration. Aligns the designer's incentive with the project budget.
- Fixed fee — a single number tied to a defined scope. Good if the scope is well-bounded.
- Hourly with cap — for early phases when scope is uncertain.
Fixed fee with a clearly-defined scope works best if you know what you want. Percentage works best if scope is still moving.
Where to find a designer or architect
Three reliable channels, in order of how the founder would actually shop:
- Recent permit history. Portland Maps Permits & Inspections — filter recent residential addition permits in your neighborhood. Designers of record who appear repeatedly are local specialists who already know what PP&D expects. Single best discovery channel.
- GCs from your feasibility walk-through. Builders know designers they like to work with — biased toward designers who collaborate well, which is what you want.
- AIA Portland. AIA's Portland chapter maintains a residential referral list — useful when you specifically want a licensed architect (vs. a CCB-registered residential designer).
What to look for: recent PP&D submittals on similar project types and price band; finished projects you can visit; clear scope and fee structure; willingness to describe what's NOT in the design fee (construction administration is the most commonly excluded). Three meetings, three proposals, one hire — pick the designer who asked the best questions about your house and your budget, not the one with the most polished portfolio.
Initial payment ("deposit")
Most architects and residential designers ask for an initial payment of 5–15% of their fee before producing drawings. Per AIA standard practice for architect compensation, this is a non-refundable initial payment held on account against the final invoices, not a refundable retainer — if you cancel mid-project, it's gone. Trades that order custom materials (cabinets, windows, specialty doors) also typically require a deposit at order time — often 30–50%, because those items aren't returnable.
