Add livable square footage without moving
Washington's ADU rules have loosened considerably, and Vancouver homeowners are using that to add rental income, house family, or create a work-from-home space that isn't a spare bedroom. The build itself is straightforward; the permitting, utility connections, and egress requirements are where projects stall.
We manage the whole thing — feasibility, design coordination, permits, trades, inspections, and finish work — as one written scope with one accountable lead.

Garage Conversion
The most cost-effective ADU: insulate, add egress and a bathroom, upgrade electrical, and finish.

Detached ADU
New slab or crawlspace, framing, utility trenching, and finish for a standalone backyard unit.
Permits & Zoning
Setback, lot coverage, parking, and utility review, then permit submittal to the jurisdiction.
Utilities & Systems
Sub-panel, water and sewer connection, mini-split HVAC, and ventilation to code.
Rental-Ready Finish
Durable flooring, efficient kitchen layout, laundry, and finishes chosen for tenant turnover.
Vancouver ADU FAQ
Can I build an ADU on my Vancouver lot?
Most single-family lots now allow one, but setbacks, lot coverage, and utility access decide the specifics. We run a feasibility review before you commit to a design.
What does an ADU cost in Clark County?
Garage conversions typically land well below a detached build, since the shell already exists. Detached units cost the most because of foundation and utility trenching. We give a firm written number after the site visit.
How long does the process take?
Permitting is usually the longest phase. Construction on a conversion runs a couple of months; a detached unit runs longer.
