Adding Value To Your Property

Converting a garage into a home office, studio, or rentable living space is one of the most popular projects we build right now in Eugene, Springfield and surrounding areas. Foshay Contracting handles the permits, framing, insulation, drywall, flooring, layout changes, and the electrical, plumbing, and HVAC work needed to make the space comfortable and functional.

What we do

Garage Conversions Add Space & Value

ADU & Living Space Conversion

We convert garages and underused areas into finished living spaces, home offices, bedrooms, studios, and ADU-style spaces for homeowners throughout Eugene, Springfield, and Lane County. The project is planned around the existing structure so the finished space feels like a natural extension of the home instead of a converted garage.

New Windows & Doors

New windows, sliding doors, and exterior doors can completely change the comfort, natural light, and usability of a converted space. We modify existing openings or create new ones as needed, then properly frame, flash, seal, and finish each installation for long-term weather protection in Western Oregon.

Insulation & Weatherproofing

Garage conversions require more than finished walls to become comfortable year-round living space. We improve insulation and weatherproofing around walls, ceilings, doors, windows, and other vulnerable areas to help control drafts, moisture, and temperature changes common throughout the Eugene, Springfield and surrounding areas.

Flooring & Floor Leveling

Garage slabs are often uneven, sloped, or not ready for residential flooring without additional preparation. We level and prepare the floor before installing LVP, hardwood, tile, or other finished flooring so the converted space looks and feels consistent with the rest of the home.

Electrical, Plumbing & HVAC

We coordinate the electrical, plumbing, and HVAC work needed to turn unfinished garage space into a functional part of the home. This can include new outlets and lighting, plumbing for bathrooms or living areas, and heating and cooling solutions such as duct extensions or mini-split systems.

Drywall, Trim & Paint

Once the structural and mechanical work is complete, we finish the space with drywall, interior trim, doors, baseboards, and paint. Finishes are selected and installed to blend with the existing home, giving Eugene and Springfield garage conversions a clean, complete residential appearance.

Straight answers

Cost, Timeline, Warranty & Financing

What it costs

Cost depends on the scope of the conversion, whether plumbing and HVAC are being added, and the condition of the existing garage structure. An in-home inspection is the only way to get accurate pricing.

How long it takes

Timeline depends on how much framing, insulation, drywall, and mechanical work the conversion needs. We give a firm timeline once we’ve inspected the garage in person.

Our warranty

Coverage holds until you’re satisfied, with no arbitrary cutoff date. If something shifts or needs attention after the conversion, we come back and fix it.

Financing available

Hearth financing is available with flexible payment options, so a garage conversion doesn’t have to wait until the full budget is saved up.

What Our Clients Say

★★★★★

“Foshay Contracting is incredible. I have worked with Josh and his crew for several projects, and I feel grateful to know of a reliable, honest contracting company we can call for future projects. One of our projects was complicated, installing an access door for our garage that is built into a hill. After reviewing several options and considering our budget, Josh and Mike created a solution that didn’t cost us a ton of money but resolved our problem.”

How much does it cost to convert a garage into living space in Eugene or Springfield?

The cost depends on the size and condition of the garage, the intended use of the space, insulation, electrical work, heating and cooling, flooring, windows, plumbing, and any structural changes required. A simple office or bonus room conversion may cost considerably less than a full bedroom suite or ADU with a bathroom and kitchen. An on-site evaluation is the best way to determine an accurate budget.

Do I need a permit to convert my garage into living space in Eugene or Springfield?

Yes, in most cases. Converting a garage into habitable living space generally requires a building permit, and additional electrical, plumbing, or mechanical permits may be needed depending on the project. The exact requirements depend on the property, existing structure, and intended use of the converted space.

What happens to the garage door during a garage conversion?

The existing garage door opening is often reframed and finished as an exterior wall. Depending on the design, the new wall may include windows, a patio door, or another exterior entrance. The goal is to make the former garage look and function like an intentional part of the home rather than simply covering the garage opening.

How do you heat and cool a converted garage?

Heating and cooling options depend on the size of the conversion and the existing HVAC system. A ductless mini-split is often practical for garage conversions because it can provide both heating and cooling without extending the home’s existing ductwork. In some projects, the main HVAC system can also be extended if it is properly sized for the additional space.

Can you add a bathroom or kitchenette to a garage conversion?

Yes, if the property layout and plumbing system make it feasible. Adding a bathroom or kitchenette usually requires plumbing, electrical, ventilation, and additional permitting. The location of existing water and sewer lines can significantly affect the complexity and cost of the project.

How long does a garage conversion take?

The timeline depends on the scope of the project and permitting requirements. A straightforward conversion into finished living space may take several weeks, while projects involving structural changes, bathrooms, kitchens, or ADU requirements can take longer. Permitting and inspections should also be included in the overall project timeline.

Can a garage conversion increase the value of my home in Eugene or Springfield?

A well-designed and properly permitted garage conversion can increase a home’s usable living space and may improve its overall value and appeal to future buyers. The actual impact depends on the quality of the conversion, how the new space is used, local buyer demand, available parking and storage, and whether the work was completed with the required permits. In some homes, converting a garage can add valuable living space, while in others the loss of enclosed parking may offset some of that benefit.
