General Contractor in Sherwood, Oregon

A town with an 1890s main street on one edge and farm fields on the other. We build for both — and for everything filling in between.

Who is the best general contractor in Sherwood?

Green O Construction is a CCB #204939 unlimited general contractor, veteran-owned since 2008, based twenty minutes up Highway 99W in Beaverton. We work Sherwood's whole spectrum — Old Town's 1890s housing, the 90s-2000s subdivisions, and rural shops on Ladd Hill acreage — with permits pulled in our name.

Building in Sherwood: a small town growing on purpose

Sherwood is a Washington County city of roughly 20,000 that has multiplied several times over since the 1990s, and the growth is not done. In December 2024 the Metro Council voted to bring the roughly 1,200-acre Sherwood West urban reserve inside the regional urban growth boundary — a decision upheld by the state in September 2025 — which sets up the largest expansion in the city's history. That is the Sherwood pattern: an 1889 railroad town at the core, rings of subdivisions around it, and a hard edge where the streets simply stop and farmland starts.

For construction, that edge matters. Inside city limits, permits run through the City of Sherwood. Step past the boundary toward Ladd Hill or the Middleton corridor and you are on unincorporated county land with different rules, different setbacks, and — on acreage — septic and well considerations the city never asks about. We work both sides of that line weekly, so the first thing we check on any Sherwood lead is simple: which jurisdiction actually owns your permit?

What we build in Sherwood

Old Town remodels

Old Town's houses predate almost every code on the books. Remodeling one means EPA lead-safe containment (we hold the LBPR credential), framing corrections made a century after the fact, and finish work that fits the street. Our architect drafts in-house, so a wall you want moved gets an engineered answer, not a guess.

Subdivision roofing + exteriors

Whole Sherwood neighborhoods were roofed in the same two-year window, so failures arrive street by street. As a CertainTeed SELECT ShingleMaster 4-Star contractor we replace builder-grade three-tab with dimensional systems, correct the ventilation the production builder skipped, and register the 50-year material warranty in your name — not the neighborhood's.

Shops, barns + rural outbuildings

Toward Ladd Hill and the rural fringe, the request changes: a shop with a real concrete apron, a pole structure done right, a barn conversion with power and plumbing that passes county inspection. We own our excavators, keep PE engineering partners on retainer, and handle the county permit path from first call to final.

Storm restoration

Sherwood's exposure runs southwest — wind comes across open farmland with nothing to slow it down before it hits the first line of fences and roof edges. After wind events we inspect, tarp same-day when the envelope is breached, and write scopes in the format insurance adjusters approve without three rounds of supplements.

Sherwood areas we work

From the historic grid to the last paved street before farmland, here is how Sherwood reads from the field.

Permits through the City of Sherwood

Inside city limits, building permits run through the City of Sherwood Building Department at 22560 SW Pine St — part of the Community Development department that also houses Planning and Engineering, which keeps plan review conversations short. Residential and commercial plan review and inspections are handled by the city.

Outside city limits — Ladd Hill, parts of Middleton, and rural parcels — permits shift to Washington County (or Clackamas County south of the ridge), and the rules shift with them. We confirm jurisdiction on day one so the application lands on the right desk the first time.

City or county, the permit goes in Green O's name. Our license carries the code responsibility, and you keep a clean, inspectable paper trail for resale.

What a typical Sherwood job looks like

A representative scope for this market: a late-90s two-story in Woodhaven with the original builder-grade roof at year 26 — three-tab shingles lifting at the edges, bathroom fans venting into the attic instead of through the roof, and moss doing what moss does on the north slope. The rebuild: full tear-off, dimensional CertainTeed system, new intake and ridge ventilation, fan ducts terminated through proper roof caps, and gutters sized for the fir debris. Two days on the roof, one permit file with the city, warranty registered to the homeowner the same week.
