A finished basement is the most affordable square footage you can add, because the structure and roof already exist. The work is about moisture control, egress, insulation, and finish, not new foundation.
Done right, a Hillsboro basement becomes a true second living level: a family room, guest suite, office, or even an income unit. Done wrong, it traps moisture and fails inspection. In our climate, the details below grade matter more than anywhere else in the house.
The right partner waterproofs first, builds to egress and insulation code, and delivers a lower level that feels as warm and dry as the rest of your home.
A basement remodel in Hillsboro typically runs $50 to $110 per square foot to finish, with most full projects landing between $40,000 and $120,000+ depending on moisture work, egress, bathrooms, and finish level.
Finished basement space is among the lowest cost-per-square-foot living area you can add to a Hillsboro home, and a legal lower-level suite can also generate rental income or house multigenerational family.

A basement is square footage you are already paying for. Finishing it is the cheapest way to add a family room, guest suite, office, or gym to a Hillsboro home, without the cost or permitting of building up or out.
The payoff is flexibility. A finished lower level absorbs the functions a busy household outgrows, from a teen hangout to a work-from-home office for the Intel and Genentech crowd, to a private suite for visiting family.
Built correctly, with moisture control and egress handled first, a finished basement adds genuine, livable space and real resale value. A legal suite can also offset the mortgage as a rental in Hillsboro’s tight housing market.
Woodland Construction Group · 18 Years Experience · Serving Hillsboro, Oregon
Our licensed team finishes and remodels basements across Hillsboro and Washington County with a moisture-first approach, handling waterproofing, egress, insulation, and finish so the lower level performs in the Pacific Northwest.
Finished basement space is some of the lowest cost-per-square-foot living area you can add to a Hillsboro home, and a legal lower-level suite can also generate rental income.
Daylight and full basements are common in Hillsboro’s mid-century and split-level homes near Reedville and Jackson School, and they are some of the best candidates for finishing in Washington County. The catch is our climate: the Tualatin Valley water table and steady winter rain make moisture control the first job, not an afterthought.
Newer two-stories in Brookwood and parts of South Hillsboro sometimes have unfinished lower levels or crawl spaces with finishing potential. We assess drainage, grading, and existing waterproofing before we frame a single wall.
A finished basement requires building, electrical, plumbing, and mechanical permits, and bedrooms below grade must meet egress-window and ceiling-height code. We handle the full permit set and inspections through the City of Hillsboro Permitting Center so your lower level is legal, safe, and dry.
Six things separate a basement that lasts from one that fails inspection or smells of damp. Each is engineered for a Pacific Northwest lower level, where what you do below grade matters most.
Drainage, vapor barriers, sump systems, and proper waterproofing handled first, so the finished space stays dry through Oregon’s wet season.
Code-compliant egress windows and wells for any below-grade bedroom, plus smoke and CO protection, so the space is legal and safe to sleep in.
Wall and floor insulation and tuned-in heating that make the lower level feel as comfortable as the main floor, not a cold afterthought.
Bedrooms, full bathrooms, and even kitchenettes built to code for visiting family, long-term guests, or a private multigenerational space.
Family rooms, home theaters, gyms, and play spaces with the wiring, lighting, and sound treatment each use actually needs.
Where zoning allows, a legal income or in-law suite with its own entrance, kitchen, and bath, designed to City of Hillsboro standards.

We had our 1,250 sq ft unfinished basement completely remodeled, a full bathroom, two bedrooms, and a family entertainment room with a custom bar and luxury hardwood. Tyrone and Anna listened to our ideas and made the process stress-free. We absolutely love it.
Woodland completed a full basement remodel for us, two egress windows, a kitchenette, full bathroom, two bedrooms, a family room, and a laundry room. The egress windows brought in so much natural light, and the craftsmanship is top-notch. Delivered on time and within budget.
Great communication and very reliable work done by Tyrone. Would definitely hire again for future projects.

A typical Hillsboro basement finish takes 6 to 12 weeks depending on size, moisture work, and whether it includes a bathroom or kitchenette. Projects that need drainage correction or egress windows added run toward the longer end. We set the schedule during design.
Finishing a basement in Hillsboro generally runs $50 to $110 per square foot, with most full projects between $40,000 and $120,000+. Moisture remediation, egress windows, bathrooms, and a kitchenette for a suite raise the figure. You get an itemized estimate during the consultation.
Yes. Finishing a basement requires a building permit plus electrical, plumbing, and mechanical permits as applicable. Any below-grade bedroom must meet egress and ceiling-height code. Woodland handles every application and inspection through the City of Hillsboro Permitting Center.
Moisture control comes first. We assess grading, drainage, and existing waterproofing, then add the drainage, vapor barriers, sump systems, and sealing needed before any framing. In the Tualatin Valley climate, this is the single most important step.
Often, yes. A below-grade bedroom needs a code-compliant egress window and well, and a legal lower-level suite needs its own egress, kitchen, and bath where zoning allows. We design to City of Hillsboro standards and manage the inspections.
Yes. It is among the lowest cost-per-square-foot living space you can add, it adds real resale value, and a legal suite can generate rental income or house family in a tight Hillsboro housing market.
Possibly. Code sets a minimum finished ceiling height, and some homes need underpinning or floor lowering to meet it, which adds cost. We measure and assess feasibility honestly during the consultation before you commit.
