Turn Your Garage or Basement into a Cash-Flowing Asset
Leverage WA House Bill 1337 to unlock rental income. We specialize in STFI Garage Conversions, Basement Suites, and ADU/DADUs across Seattle & Surrounding Areas
Let’s Discuss Your Project
Maximize Your Existing Footprint
Garage Conversion (STFI)
The fastest path to ROI. For qualifying garages under 750 sq. ft., we utilize Subject to Field Inspection (STFI) permits to bypass long city reviews and get you building faster.
Basement Income Suites
Unlock the value inside your thermal envelope. We handle the complex structural underpinning and egress window requirements to turn dark storage into a legal, fire-rated apartment.
Suburban Integration
We respect your neighborhood's character. Our designs match your existing rooflines and siding (ACC 18.32 compliant), ensuring your addition looks cohesive and natural.
Future-Proof Investment
Building for equity? We design independent structures ready for future condoization, allowing you to potentially split your lot and sell the unit separately down the road.
The Financial Reality
We don't hide the "Soft Costs." Here is the reality of building a legal unit in 2025.
The Soft Costs
Architectural plans, structural engineering, and city impact fees typically range $10k - $20k before hammers swing. We manage this entire bureaucratic process for you.
The Hard Costs
Quality labor and materials in the Puget Sound region run $120 - $300/sq. ft. We provide detailed, line-item proposals so you see exactly where every dollar goes.
The ROI
With rental rates in King County averaging $2,200+ for ADUs, most projects generate positive cash flow immediately after financing is settled.
Our Proven Process
From initial consultation to final inspection, we handle every step of your conversion project.
Zoning & Feasibility Audit
We analyze your lot's specific zoning (Seattle NR vs. Auburn City Code) to confirm exactly what you can build before you spend a dime on design.

Design & Engineering
We create smart floor plans that maximize limited square footage while solving for insulation, egress, and fire separation requirements.
Permitting (Change of Use)
We manage the complex 'Change of Use' permit process with the city to legally reclassify your garage or basement as habitable space.
Construction & Utilities
We expertly run new plumbing, electrical, and HVAC lines into your existing walls, ensuring a seamless connection to your main systems.
Final Inspection
We walk the final inspection with city officials to ensure your new unit is fully certified for occupancy and rental use.
