We Handle the Hard Part. Clackamas County ADU, Garage & Shop Builder
With 15+ years building residential, Friday Design Build handles the drawings, the permits, and the crews — one team, start to finish. Get real numbers before anything starts — whether it's an unfinished garage shell or a fully finished ADU.
What you get with Friday
Why Friday?
Start to Finish
We handle the whole process — design, zoning, permits, inspections, and construction — from the first sketch to the final walkthrough. You pick finishes and watch it go up; the paperwork never lands on your desk.
A Number Up Front
Tell us what you want to build and you'll get an estimated cost range back — before the site walk, before you commit to anything. The real, fixed bid comes with the paid Design Agreement.
ADUs
From $300/sq ft · Shell or Turn-KeyStudio through two-bedroom accessory dwellings — 400 to 800 SF. Rental income, aging parents, or a returning kid: same building. Take it turn-key to occupancy, or take the shell and finish the interior yourself.
Price My ADU
Garages, Shops
& Additions
From $115/sq ft · Detached, attached & shops
Detached and attached garages, plus shops and workspaces. Framed for the ceiling height you actually need — lifts, lofts, RV doors — and, on attached builds, matched to your existing home so it reads as original.

We Make It Easy.
Construction gets complicated fast — jurisdictions, permits, feasibility, financing. We've been navigating that for 15+ years, so we take on the heavy lifting. Two simple agreements: a design agreement to lock in your plans, then a construction contract with firm pricing.
Free Site Walk
We meet at your property, walk the lot, and answer your questions — no cost, no obligation.
Design Agreement
A paid engagement to draw the plans, pull the permits, and produce a fixed bid — with subcontractor walk-throughs so the number is real.
Construction Contract
Design and price are locked. We sign the construction contract, get the trades scheduled, and start building.
Complete
Inspections closed, punch list handled, keys in hand. Increased value, real space, jealous neighbors.

We Love Our Clients.
Erich with Friday Design Build was great to work with. I hired Erich to build a detached ADU and garage in my backyard, and he walked us through the design, permitting, demolition, and construction process. He made everything easy to navigate and worked with us to build something we love while staying within our original budget. I would highly recommend Friday Design Build to anyone considering building an ADU on their residential property.
