ADU Builder in Eugene, Oregon
Oregon's ADU rules changed — you can likely build an accessory dwelling unit on your Eugene lot now. HomeShield Construction handles the whole thing: feasibility, design coordination, permitting, utilities, and the full build from slab to certificate of occupancy — at a fixed price.
- Detached ADUs, garage conversions, and attached in-law suites
- We confirm what your lot and Eugene/Lane County code actually allow
- Permitting, utility hookups, and inspections managed in-house
- Fixed price in writing before work starts — no draw-by-draw surprises
Building an ADU in Eugene, done right
An ADU is one of the highest-return things you can build on a Eugene lot — rental income, multigenerational living, or a future downsizing option. But the value only shows up if it's permitted correctly and built to last, and that's exactly where DIY-ish contractors get homeowners in trouble.
We start by confirming feasibility: setbacks, lot coverage, utility capacity, and current Eugene/Lane County ADU rules. Then we coordinate design, pull the permits, and build with the same crew you met on day one. You're never handed off to a stranger halfway through.
Because the whole project is under one fixed-price contract, the hidden-condition surprises that blow up ADU budgets — a utility run that's farther than expected, a foundation detail the soils report demands — are our problem to solve, not a change order for you.
What's included
Every project is one fixed-price contract with the same licensed crew from consultation through final walkthrough.
Feasibility + code check
Before you spend on design, we confirm what your specific lot allows under current Eugene/Lane County ADU rules.
Design coordination
We work with your designer or bring one in, matching the ADU to your main home and your budget.
Full permitting
Building, electrical, plumbing, and mechanical permits pulled and managed in-house — with the inspections scheduled for you.
Utilities + site work
Water, sewer, and electrical hookups, plus grading and drainage handled as part of the fixed price.
Complete build
Foundation to finishes — framing, systems, insulation, and interior — by one licensed crew, start to finish.
Certificate of occupancy
We take it all the way through final inspection so your ADU is legal to live in or rent the day we hand you the keys.
How we work
Free on-site consultation
We walk the project with you, document the scope, and talk through goals and constraints before any numbers change hands.

Frequently asked
Can I build an ADU on my Eugene lot?+
Most likely, yes — Oregon and Eugene loosened ADU rules significantly. The real answer depends on your lot's size, setbacks, and utilities. We check all of that for free during the consultation before you commit to anything.
How much does an ADU cost in Eugene?+
A detached ADU of roughly 400–800 sqft typically runs $120k–$250k depending on size, site conditions, and finishes. Garage conversions are often less. You get an exact fixed price in writing after the site visit.
How long does an ADU take to build?+
Plan on 4–7 months for a detached ADU including permitting, sometimes faster for a conversion. We give you a milestone schedule with buffer before you sign.
Do you handle the permits?+
Yes — all of them, in-house. Building, electrical, plumbing, mechanical, and the inspections. ADU permitting is where most delays happen, so we manage it directly.
