Planning a home addition in Beaverton, Oregon? When your family outgrows a ranch or two-story but loves the neighborhood and schools, an addition is the answer, and Beaverton’s larger lots often give you room to build out. It extends your footprint or adds a level with new foundation, framing, roofing, systems, and finishes that tie cleanly into your existing house.
It gives you the extra bedroom, primary suite, or larger kitchen you need while keeping the west-side neighborhood, schools, and lot you already love. Because the work involves structure, Beaverton and Washington County setback rules, and a seamless tie-in, the contractor you choose controls the outcome.
The right partner gets the engineering and Building Division permits right, matches the new space to a ranch or two-story, protects your budget, and holds your schedule from groundbreaking to final walkthrough.
A home addition in Beaverton typically runs $80,000 to $300,000+ in 2026, depending on whether you extend a ranch at grade or build a second story that needs foundation reinforcement. As a rule of thumb expect $200 to $500 per square foot, with at-grade additions on Beaverton’s roomier lots often landing more efficiently than going up.
An addition lets you gain the space your family needs without buying a larger home in the same Beaverton school district, where move-up homes are competitive, and the added square footage increases resale value, making it one of the strongest long-term investments on the west side.

An addition solves the space problem without leaving the Beaverton schools and neighborhood you chose. You keep your location, your lot, your schools, and your neighbors, and you gain exactly the room your family is missing, tailored to how you actually live rather than whatever happens to be on a competitive west-side market.
The 2026 Beaverton addition is about seamless integration. Done right, a new primary suite over a ranch or an expanded family room reads as part of the original house, matching rooflines, siding, and finishes so there is no visible seam between old and new. That continuity is what protects both daily livability and resale value on the west side.
Pair that with how competitive larger homes are in Beaverton’s school districts, and a well-built addition delivers an immediate lifestyle upgrade and a strong long-term return. Considering a separate unit on your lot instead? See our ADU builder page.

Our team of licensed contractors specializes in room and second-story additions across the Portland metro, handling structural engineering, permitting, and seamless tie-ins to the existing home.

Six addition types show up most often on Beaverton’s lots. Each one is engineered to expand your home, out or up, and tie into the existing structure seamlessly, not just bolt on more space.
New bedrooms, family rooms, offices, or expanded living space built out at grade, the most efficient option on Beaverton’s roomier lots, with new foundation, framing, and a clean tie-in to the existing home.
Building up to roughly double your living space when the lot is tight or sloped, with the structural engineering and reinforcement to carry a new level safely over a ranch or two-story.
Spacious primary bedroom additions with walk-in closets and en-suite baths, a popular way to give a 1960s Beaverton ranch the owner’s retreat it never had.
Attached suites with their own kitchen, bath, and entrance for family or rental income, designed to meet Beaverton and Washington County accessory dwelling requirements.
Light-filled sunrooms and kitchen or family-room bump-outs that add usable square footage and open a west-side home onto its yard.
Rooflines, siding, windows, trim, and finishes matched to the original house so the addition reads as part of the home, whether it is a mid-century ranch or a newer Beaverton build.
How We Work
One team, one contract, from the first measurement to the final walkthrough, with no handoffs between designer, builder, and trades: design and 3D layouts, material selection, permitting and inspections, careful demolition, licensed construction, and a final walkthrough, all backed by our 1-year craftsmanship warranty.

We had outgrown the house but did not want to leave our neighborhood. The addition gave us the family room and extra storage we were missing. What impressed us most is that it does not look added on - the transition from the original house feels natural.
Adding a bedroom and bathroom was a much larger undertaking than any project we had done before. Tyrone helped us understand the order of construction and what decisions had to be made early. Having a clear process made the project feel manageable.
We were concerned about matching the exterior materials on a house that is more than 30 years old. Woodland took the time to find finishes that worked with what was already there. The new section looks like it has always been part of the home.
Timelines, permits, cost, and what an addition on a Beaverton lot involves in 2026. If your question is not here, call us. We would rather answer it directly.
A typical Beaverton home addition takes 3 to 6 months from groundbreaking to final walkthrough, depending on size and complexity. A single-room or at-grade bump-out can finish in 2 to 3 months, while a second-story addition or large multi-room expansion with new foundation work can run 5 to 8 months. We set a detailed timeline during design and hold to it.
In Beaverton, home additions run $80,000 to $300,000+ in 2026 depending on size, type, and finish level. As a rule of thumb, expect $200 to $500 per square foot, with second-story additions and work requiring new foundation or structural reinforcement landing at the top of that range, and at-grade additions on roomier lots often more efficient. You get an itemized estimate during the consultation phase.
Yes. Home additions require building permits and often zoning review, since you are changing the footprint or height. Setbacks, lot coverage, and height limits all come into play, and they vary by zone across the west side. We handle every application, structural engineering, inspection, and coordination through the City of Beaverton Building Division, or Washington County for unincorporated lots, to keep the project compliant and on schedule.
Yes. A seamless addition is the whole point. Our design team matches rooflines, siding, windows, trim, and interior finishes so the new space reads as original construction, not a bolt-on. We pay close attention to how the addition ties into existing structure and flow, whether your Beaverton home is a 1960s ranch or a newer two-story.
We build room additions, second-story additions, primary suite additions, in-law and ADU suites, sunrooms, family-room and kitchen bump-outs, and garage conversions. Whether you need one more bedroom, a larger kitchen, or a whole new level, we design the addition around how your family lives and how it fits your Beaverton lot, zoning, and budget, often building out where the lot allows.
Usually, yes, and an at-grade addition makes it easier. Because the work mostly happens alongside the existing structure, most Beaverton families stay in their home throughout, with a temporary wall sealing the work area until we connect the new space. For a second story we plan the open-roof phases tightly and keep your home secure and weather-tight the entire time.
Yes. An addition lets you gain the bedroom, suite, or living space your family needs without leaving the Beaverton schools, neighborhood, and lot you love, often for less than buying a larger home in the same competitive district. Added square footage also increases resale value, which makes a well-built addition one of the strongest long-term investments on the west side.
Built for Beaverton
Adding on in Beaverton often means building out, not just up. The larger suburban lots of Murray Hill, Sexton Mountain, Cooper Mountain, and Five Oaks usually leave room to extend a ranch at grade, push out a primary suite, or add a family room and still meet setbacks. Where lots are tighter or sloped, we build up instead. Either way, the goal is the same: more room that ties into the existing house so cleanly that no one can tell where the original ends.
A few west-side realities shape every addition. Building permits, structural engineering, and zoning review for setbacks, lot coverage, and height route through the City of Beaverton Building Division, with some unincorporated lots handled by Washington County instead. We confirm what your lot and zone allow before design begins, then manage the engineering, permits, and inspections so the addition clears the right jurisdiction and matches your home inside and out.
Family-owned and based in Northwest Portland, we build home additions across the city and the west-side suburbs.
