Tigard General Contractor Built for Hillside Homes
Tigard runs from Bull Mountain's slopes down to the Tualatin River floodplain. The contractor you hire should understand both ends of that hill.
Who is a good general contractor in Tigard?
Green O Construction is a CCB #204939 unlimited general contractor 15 minutes north of Tigard, veteran-owned since 2008, with PE engineering partners on retainer, our own excavators, and a CESCL erosion-control credential - the combination hillside work on Bull Mountain actually requires.
What building in Tigard actually looks like
Building on your Tigard lot depends on where it sits: Bull Mountain climbs over 700 feet with steep, wind-exposed slopes, the valley floor along 99W carries 1960s-80s subdivisions, and the southern edge drops to the Tualatin River floodplain with Fanno Creek threading the whole city. Terrain, not preference, writes the scope.
- Tigard counted 54,539 people at the 2020 Census.
- Retaining walls over four feet on Bull Mountain need PE-stamped engineering.
- Floodplain and wetland setbacks along Fanno Creek and the river decide what a lot can take before design starts.
- The January 2024 ice storm hit Bull Mountain's firs hard; the June 2021 heat dome aged south-facing roofs a decade in three days.
- Four housing eras: postwar Metzger ranches, 70s-80s Summerlake, 90s-2000s Bull Mountain, and River Terrace still building today.
Tigard counted 54,539 people at the 2020 Census, spread across terrain that changes more in three miles than most cities change in twenty. Bull Mountain climbs over 700 feet on the west side - steep, wooded, and wind-exposed. The valley floor along 99W carries the 1960s-80s subdivisions of Summerlake and Metzger. And the southern edge drops to the Tualatin River, with Fanno Creek threading the whole city on its way there.
That geography writes our scopes. On Bull Mountain, gravity is the client: retaining walls over four feet need PE-stamped engineering, downhill lots need drainage designed before anything else, and erosion control is not optional on a sloped dig - it is why our CESCL credential earns its keep here. Down along Fanno Creek and the river, floodplain and wetland setbacks decide what a lot can take before design starts, and crawlspace moisture is the first thing we check on any remodel bid.
Weather runs the same calendar as the rest of the metro - November-to-April wet season, the June 2021 heat dome that aged south-facing roofs a decade in three days, and the January 2024 ice storm that hit Bull Mountain's firs hard enough to keep tarp crews busy for weeks. Elevation makes the difference: the top of the hill ices while the bottom rains.
The housing stock tracks the terrain. Metzger and the Greenburg Road corridor carry postwar ranches on generous lots. Summerlake and the 99W spine were built out in the 70s and 80s. Bull Mountain filled in through the 90s and 2000s with larger two-stories on engineered pads, and River Terrace is still coming out of the ground today. Four eras of construction means four different failure patterns - and we have opened walls in all four.
What we build in Tigard
In Tigard you can call us for roofing, siding, interior and accessibility remodels, additions and ADUs, structural and drainage work, commercial tenant improvements, storm restoration, and maintenance membership. Structural is our busiest Tigard category, with engineered retaining walls, French drains, and hillside water management built for Bull Mountain's slopes.
- Roofing: CertainTeed SELECT 4-Star install with the warranty registered in your name.
- Structural: PE partners on retainer, owned excavators, CESCL erosion control on every sloped dig.
- Additions + ADUs: free lot check reads grade, setbacks, and utilities; Metzger's larger lots are some of the best ADU ground in Washington County.
- Storm restoration: 24-hour callback, same-day tarps, and drone documentation written the way adjusters approve.
Roofing
Bull Mountain roofs take more wind and more debris than valley-floor roofs, and Summerlake's 1970s-80s stock is on its second or third cycle. CertainTeed SELECT 4-Star install, warranty registered in your name, and a straight answer when a repair is the smarter buy.
Exterior + Siding
Metzger ranches with original T1-11 and Summerlake homes with tired lap siding both get the same treatment: WRB flashed first, Hardie or LP installed to spec, manufacturer warranty in the homeowner's name.
Interior Remodel
Kitchens and baths across Tigard's 60s-80s housing stock, plus accessibility remodels near King City - curbless showers, wider doorways, grab-rail blocking done during the remodel instead of bolted on after.
Additions + ADUs
Metzger's larger lots are some of the best ADU ground in Washington County. On Bull Mountain, slope decides feasibility - our free lot check reads grade, setbacks, and utilities before you spend on drawings.
Structural
Our busiest Tigard category: engineered retaining walls, French drains, foundation repair, and hillside water management on Bull Mountain. PE partners on retainer, owned excavators, CESCL erosion control on every sloped dig.
Commercial
Tenant improvements and flat-roof work in the Tigard Triangle and along the 99W corridor - COI with additional insured in 24 hours, off-hours scheduling for open storefronts.
Storm Restoration
When ice loads Bull Mountain firs, limbs find roofs. 24-hour callback, same-day tarps, drone documentation, and claim scopes written the way adjusters approve them.
Maintenance Membership
Hillside homes under firs need their gutters, valleys, and drains checked every year - membership puts that on our calendar so it never falls off yours.

Permits through the City of Tigard
Your Tigard building permit runs through the Community Development department's Permit Center at 13125 SW Hall Blvd, with applications filed through the online Community Development Hub. We file digitally, track review from our office, and pull every permit in Green O's name so the code exposure sits with our license, not yours.
- The Permit Center is open Monday through Thursday, 8 AM to 6 PM.
- Parts of Bull Mountain remain unincorporated Washington County, so jurisdiction gets confirmed on day one.
- Projects near Fanno Creek or the Tualatin River can touch floodplain and sensitive-lands review.
- Fees run from project valuation on the city's adopted fee schedule, line-itemed before you sign.

Two Tigard-specific wrinkles worth knowing. Parts of Bull Mountain remain unincorporated Washington County, so jurisdiction gets confirmed on day one - filing at the wrong counter costs weeks. And projects near Fanno Creek or the Tualatin River can touch floodplain and sensitive-lands review, which we scope into the calendar up front instead of discovering at plan check.
On fees: Tigard calculates building permit fees from project valuation on the city's adopted fee schedule, and engineered work like retaining walls adds a plan review line. We put every city fee in the written scope before you sign - the number you approve is the number you pay.
Every permit goes in Green O's name - the code exposure sits with our license, not yours - and we meet the inspector at every hold point.
A representative Tigard job
Picture a 1990s home on Bull Mountain's north slope: winter water sheeting off the uphill neighbor's lot, a bowing timber wall at the property line, and a wet crawlspace every February. The right scope is a PE-engineered segmental block wall with drain rock and geogrid, a French drain intercepting the uphill flow, downspout tie-ins to daylight, and CESCL erosion control through the wet-season dig. Roughly a two-week job - and the crawlspace stays dry because the water never reaches the house.
