Eugene made it easier
than ever to build.

Full plan documents and drawings available through the City of Eugene's ADU program. We'll help you pick the right plan for your lot.
Built for your lot,
your style, your life.
Pre-approved plans are a great fit for many lots — but not every property is standard. If you have an irregular lot, specific design goals, or want something beyond the 13 plans, we design and build fully custom ADUs from the ground up.
Lot Optimization
Custom siting to maximize your yard, views, and privacy — designed around your specific parcel and setbacks.
Custom Floor Plans
Design the layout you actually want — number of bedrooms, bathroom configuration, kitchen placement, indoor/outdoor flow.
Energy Efficiency
Specify insulation, windows, HVAC, and solar-ready design from the start. Build it right the first time.
Permit Management
We handle every permit, inspection, and city coordination — so you don't have to become an expert in Eugene's building code.
Don't have the right lot yet?
We can help with that too.
Not every ADU project starts with a property that's ready to build on. Whether you're shopping for a lot, want to add infill to your current property, or need help figuring out if your yard can actually support an ADU — we do that work with you.
Find the Right Property
Looking for a lot that's ADU-friendly? We help you evaluate properties before you buy — checking zoning, setbacks, utility access, and slope so you know what's buildable before you close.
Infill Development
Already own a property with room to add density? We handle the full infill process: site analysis, design, permitting, and construction. Turn unused yard space into a rental unit or family housing.
Investment Strategy
Building an ADU is a real estate investment. We walk you through the numbers — construction costs, rental income potential, and property value impact — so you can make a confident decision.
From first conversation
to keys in hand.
Consultation
We assess your lot, discuss your goals and budget, and help you decide between a pre-approved plan or a custom design. No commitment, no pressure.
Design & Plan
Choose from Eugene's 13 pre-approved designs or work with us on a custom plan. We handle site-specific engineering and any required modifications.
Permits & Build
Pre-approved plans move faster through permitting — sometimes 2–4 months faster. We manage inspections and construction from groundbreak to final walkthrough.
Move-In Ready
Final inspections, certificate of occupancy, utility connections, and a full walkthrough before we hand over the keys.
The local builder
who knows ADUs.
Local Eugene Expertise
We know Eugene's zoning, setback rules, and city staff. That local knowledge prevents surprises and keeps your project on track.
Pre-Approved Plan Specialists
We've built from Eugene's pre-approved library and know which plans work best for common lot configurations in the area.
Transparent Pricing
Line-item estimates, not lump sums. You see exactly where every dollar goes — and we track it through the entire build.
Licensed & Insured
Oregon CCB licensed (#245662), fully insured, and accountable. Your ADU is backed by our reputation in the Willamette Valley.
