Professional Garage Conversions in Tacoma — From Parking Space to Living Space

Turn your underused garage into a fully finished, code-compliant living space. Cascade Pro, Inc specializes in garage-to-living-space conversions throughout Tacoma and Pierce County — handling design, permits, construction, and final inspection.

Whether you want a rental unit, guest suite, home office, or in-law apartment, a garage conversion is one of the most cost-effective ways to add usable square footage to your Tacoma property.

Types of Garage Conversions We Handle in Tacoma

Every garage is different, and so is every conversion. Here are the most common projects we take on:

Detached Garage to ADU

Converting a standalone garage into a separate living unit. This is ideal for rental income or housing a family member with full privacy and independence. We add a bathroom, kitchenette or full kitchen, bedroom area, and separate entrance.

Attached Garage to Living Space

Transforming an attached garage into an extension of your home — a bedroom suite, family room, home office, or in-law apartment. We seal the garage door opening, match finishes to the existing home, and ensure seamless integration.

Partial Garage Conversion

If you want to keep some garage storage or parking space, we can convert a portion of the garage while preserving the rest. This works well for larger two- or three-car garages.

Garage + Addition Combo

Sometimes a garage conversion works best when combined with a small addition to meet size or layout requirements. We can extend the footprint if your lot and zoning allow it.

Our Garage Conversion Process — Step by Step

Every garage conversion project follows a structured process to keep timelines tight and surprises to a minimum:

  1. Consultation & Garage Assessment — We evaluate your existing garage structure, foundation condition, ceiling height, utility access, and local zoning to determine what’s possible. We’ll discuss your goals and how to get the most value from the conversion.
  2. Design & Structural Planning — Our team designs a layout that maximizes the space — whether that’s a studio, one-bedroom, or open-concept unit. We coordinate structural engineering for any wall modifications, load-bearing changes, or foundation upgrades needed.
  3. Permits & Code Compliance — We submit plans directly to the City of Tacoma and manage the review process through all stages. Garage conversions have specific requirements for egress, insulation, electrical, plumbing, and ventilation that differ from standard remodels — we handle all of it.
  4. Construction & Build-Out — Our crew transforms the space: framing interior walls, upgrading insulation, installing electrical and plumbing, adding HVAC, hanging drywall, and completing all finishes including flooring, kitchen or kitchenette, and bathroom.
  5. Inspection & Handoff — We coordinate all required inspections and address any final items. You get a fully finished, permitted living space ready for use.

What Does a Garage Conversion Cost in Tacoma?

Garage conversions in Tacoma are generally more affordable than ground-up construction because the shell — foundation, walls, and roof — already exists. However, costs vary based on the scope of work and the condition of the existing structure.

Key factors that influence your project budget:

  • Structural condition — older garages may need foundation or framing upgrades to meet residential code
  • Plumbing scope — adding a full bathroom and kitchen costs more than a simple living space conversion
  • Electrical and HVAC — most garages need significant electrical upgrades and a new heating/cooling system
  • Garage door opening — sealing and insulating the opening with a proper wall, window, or entry door
  • Finish level — standard vs. upgraded flooring, fixtures, countertops, and cabinetry

We provide transparent, line-item estimates after evaluating your specific garage. No surprises — you’ll know what to expect before we start.
