The problem
Why most jobs like this go sideways.
Additions and ADUs die in pre-construction - drawings stall, the engineer can't be reached, the permit gets bounced for something the architect should've caught. You wanted a guest suite for your mother-in-law. You got a six-month delay and a stalled hole. You deserve a contractor who keeps the architect, the engineer, the permit, and the crew under one roof - literally on the same payroll - so the project actually moves on a calendar you can plan around.

Questions, answered
Frequently asked.
How long does an ADU take?
Detached ADU typically 5-7 months from permit issue to CO. Permits themselves are 2-4 months in most jurisdictions. We give you a real calendar before you sign - not a hopeful guess.
Can you build an ADU on my Beaverton lot?
Beaverton allows ADUs in most R-zones. We do the lot feasibility for free as the first step - so you know whether it pencils before you commit a dollar.
Do you finance ADUs?
We don't lend, but we partner with Hearth + Service Finance Co for HELOC and construction-to-perm options.
Garage conversion - do I lose my garage?
Yes if it's a full conversion. Detached ADU keeps the garage. We help you compare both options in the free feasibility - no upsell.
What happens if I pick the wrong contractor?
Wrong contractor takes a deposit, files an incomplete permit application, the city bounces it, and you sit on a stalled lot. Or worse - they pour a foundation that doesn't meet setback and you face teardown. 17 years of Beaverton permitting means we know what the inspector will flag - before he flags it.
Can you build an ADU on my Beaverton or Portland lot?
Yes — ADUs are one of our most-requested adds. We handle the survey, design, permit, foundation, framing, MEP, and finish in-house. Architect on payroll keeps the design loop tight.
How long does an addition take, foundation to final?
Most residential additions run 4-7 months from permit to certificate of occupancy. We give you a written calendar, not a verbal guess.
