Hillsboro General Contractor From Orenco to Reed's Crossing

Our Beaverton HQ sits on TV Highway - the same road that runs straight into Hillsboro. We have been working Washington County's county seat since 2008.

What building in Hillsboro actually looks like

Hillsboro is Oregon's fifth-largest city - 106,447 people at the 2020 Census and still growing - and it is really three housing markets wearing one name. Old Town around the Civic Center carries pre-war homes and mid-century ranches. The Silicon Forest era built Tanasbourne and Orenco Station for the tech workforce, and those 1985-2005 roofs and siding systems are aging out on the same schedule they went in. And South Hillsboro is brand new: Reed's Crossing alone is Oregon's largest master-planned community at 465 acres, with roughly 2,000 single-family homes planned.

That third market matters more than people think. New-construction owners in Reed's Crossing call us for what production builders leave behind: warranty punch items the builder is slow to close, fences and decks the base contract never included, and garage or bonus-room finish work. On tight new lots, HOA design standards and five-foot setbacks decide what is buildable before the tape measure comes out.

Weather is classic Tualatin Valley: a wet season from November through April, the June 2021 heat dome that cooked west- and south-facing shingles, and the January 2024 ice storm that overloaded gutters valley-wide. Hillsboro sits at the farmland edge, so wind fetch across open fields west of town hits exposed elevations harder than anything comparable in Beaverton. Growth also keeps Washington County trades busy - one more reason a complete, correct first permit submittal is worth real money in schedule time.

What we build in Hillsboro

Roofing

Tanasbourne and Orenco roofs installed in the 90s and 2000s are hitting end-of-life together. As a CertainTeed SELECT ShingleMaster 4-Star contractor, we replace them with the long-form material warranty registered in your name - and we tell you when a repair beats a tear-off.

Exterior + Siding

First-generation composite siding from the 90s boom is Hillsboro's most common envelope failure. We re-side in Hardie and LP SmartSide with the WRB flashed before board goes up - and we match HOA color and profile requirements in Orenco and South Hillsboro.

Interior Remodel

Kitchens and baths in Tanasbourne-era homes are 30 years old and showing it. Our architect drafts in-house, our finish crew closes the punch list to zero, and you sign it off before we invoice the final draw.

Additions + ADUs

Older Hillsboro lots near downtown and Witch Hazel have the room newer subdivisions do not. Our free feasibility check reads setbacks, lot coverage, and utility capacity before you pay for drawings.

Structural

Tualatin Valley clay soils move seasonally. Foundation repair, drainage, and engineered retaining walls run with PE partners on retainer and excavators we own outright.

Commercial

Hillsboro's tech economy fills strip retail, flex space, and offices that need tenant improvements and flat-roof work. COI with additional insured in 24 hours, and we know Hillsboro's planner queue is separate from Beaverton's and Portland's.

Storm Restoration

Wind off the open valley floor west of town does real shingle damage. We document with drone imagery, meet the adjuster on site, and write scopes carriers approve - 24-hour callback, same-day tarps.

Maintenance Membership

For Orenco townhomes and Reed's Crossing new builds alike: annual roof, gutter, and envelope checks that catch small failures before Washington County's wet season finds them for you.

Hillsboro neighborhoods we know

TV Highway runs from our front door into Hillsboro, which makes these neighborhoods part of our daily routes - not a special trip.

Permits through the City of Hillsboro

Building permits inside city limits run through the City of Hillsboro Development Services & Permitting Center at 150 E Main St, on the fourth floor of the Hillsboro Civic Center. Staff are available Monday through Friday, 8 AM to 5 PM, and walk-ins are welcome - a friendlier counter than most metro jurisdictions.

Homes in unincorporated pockets around Hillsboro permit through Washington County instead, and the two queues do not move at the same speed. We confirm jurisdiction on day one so your project is not filed at the wrong counter - a mistake that costs weeks.

On fees: Hillsboro building permit fees are calculated from project valuation on the city's published fee schedule, with plan review billed alongside. We line-item every city fee in the written scope before you sign, so the approved number is the real number.

Every permit goes in Green O's name. The code exposure sits with our license, we schedule the inspections, and we meet the inspector on site.

A representative Hillsboro job

Picture a 1996 two-story in Tanasbourne: original composite siding chalking and swelling at the butt joints, window flashing installed over the housewrap instead of under it, and a north wall that never fully dries. The right scope is a full tear-off to sheathing, new WRB with flashing sequenced correctly, Hardie plank with matching trim, and paint in a 15-year system - roughly a two-week job with the envelope weather-covered every night. That flashing sequence is the difference between siding that lasts 30 years and siding that rots in seven.
