Portland ADU Builder & Home Additions Contractor
New Builds, ADUs & Home Additions in Portland, Oregon
Rip City Construction builds custom accessory dwelling units and home additions throughout Portland — detached backyard ADUs, garage conversions, and ground-up construction designed for rental income, multigenerational living, or simply more space.
From feasibility and permitting through final finishes, we manage the entire build in-house. Portland's ADU rules are complex; our experience with local zoning and permitting keeps projects moving. See our recent ADU and addition projects below.
