Home Remodeling & Additions Across the Portland Metro

Masters Construction proudly serves homeowners throughout the Greater Portland Metropolitan Area, including communities in Oregon and Southwest Washington. Our second-generation building expertise, design-build capabilities, and commitment to master-level craftsmanship make us a trusted choice for premium renovations, custom additions, and outdoor living projects across the region.

Every project starts with full-service architectural design, so you can walk the design before construction begins.

We design and build custom additions for homes across the Portland Metro, managing every detail from initial concept and engineering to permitting and final finishes. Our integrated design-build approach ensures cohesive results, controlled budgets, and efficient timelines.

Masters Construction is a design-build general contractor working on both sides of the Columbia. We build from the historic streets of inner Portland to acreage in Clackamas County, and new construction in Clark County, Washington.

This page is the hub: use the county sections below to reach the city or neighbourhood page for your address. There you will find the local permitting office, the neighbourhoods we build in, and what the housing stock means for a remodel. You will also find the guides most relevant to that area.

We are licensed in both states, Oregon CCB #248237 and licensed, bonded and insured in Washington. We handle design, engineering, permitting and construction under one contract wherever we work. If your city is not listed, call us anyway.

We build throughout the metro and will tell you honestly whether your address is inside a sensible travel radius for the project you have in mind.

In Clackamas County we build in Lake Oswego, West Linn, Happy Valley, Milwaukie, Gladstone and Oregon City, Wilsonville, Stafford and Damascus and Boring.

Incorporated cities run their own building divisions. Lake Oswego, West Linn, Happy Valley, Milwaukie, Oregon City and Wilsonville each review their own permits. That is typically two to four weeks for interior remodels and six to twelve weeks for additions.

Unincorporated areas including Stafford, Boring and parts of Damascus are reviewed by Clackamas County. There, land-use review, accessory-structure limits and septic capacity often matter more than the building permit itself. Acreage properties on well and septic need a health-department review whenever bedrooms or bathrooms are added. That step, not plan review, usually sets the schedule.

In Southwest Washington we build in Vancouver, Camas, Washougal, Salmon Creek, Felida and Ridgefield.

Addresses inside city limits are permitted by the City of Vancouver, Camas, Washougal or Ridgefield. Salmon Creek, Felida and much of the surrounding area are unincorporated and reviewed by Clark County Community Development, even though the mailing address reads Vancouver.

Interior remodels typically clear review in two to four weeks and additions in six to twelve. Shoreline, wetland and floodplain boundaries near the Columbia, Lake River, Vancouver Lake and Salmon Creek are verified during design. Well or septic properties need a health-department review when bedrooms or bathrooms are added.

Masters Construction is licensed, bonded and insured in Washington and holds Oregon CCB #248237.
