Full-service ADU construction in Portland from permits through occupancy.

Local ADU Construction Expertise

In Portland, ADU construction unlocks housing options for growing families and rental income. We handle full-scope ADU builds—from permits and framing through final inspections. Our process keeps you informed every step.

How We Work

Our ADU construction approach combines permit expertise with skilled framing and quality finishing. We manage complexity so you focus on your project goals.

Planning and Permits

ADU regulations in Portland shift frequently. We navigate setbacks, lot coverage, and parking requirements so your design complies from day one. Early clarity prevents costly rework.

Framing and Structure

Precise framing sets the tone for everything that follows. We use proven techniques and quality materials to build sturdy, straight frames that take finishes well.

What's Involved

Below is the phased breakdown of ADU construction from ground-up to lockup.

Site Prep and Demo

Clear the lot, handle existing utilities, and establish grade for a clean foundation start.

Foundation and Framing

Pour foundation, install sill plate, and frame walls, roof, and floor systems with precision.

Rough Ins and Inspections

Install electrical, plumbing, HVAC rough-ins; pass framing and MEP inspections on schedule.

Enclosure and Sheathing

Sheath walls and roof, install windows and exterior doors, and seal the building envelope.

Finishes and Systems

Install drywall, flooring, cabinets, fixtures, and complete mechanical and electrical hookups.

Final Inspection and Closeout

Pass final city inspection, obtain certificate of occupancy, and complete punch list items.

You'll always know what's happening next—and when.

Permit and Compliance Support

Portland's ADU code evolves regularly. We ensure your design meets current setback, height, lot coverage, and parking standards before ground-breaking, preventing delays and rework.

Early permit clarity saves weeks of revision and rework downstream.

Custom Home and Addition Work

Beyond ADUs, we build custom homes and home additions in Portland with the same attention to code, quality, and timeline. Whether you're adding a room, expanding a kitchen, or building new, we manage the work.

Why It Matters

ADU construction is investment and compliance combined. Getting both right takes expertise in Portland's building code, material quality, and schedule discipline.

Code Compliance Prevents Costly Rework

Portland's setback and lot coverage rules shift frequently. A design that clears the city on day one prevents failed inspections, redesigns, and timeline slips later.

Permit issues caught early cost hours; caught late, they cost weeks.

Quality Framing Increases Value and Lifespan

Plumb, square framing takes drywall, finishes, and fixtures cleanly. Precision also reduces future settling and cracking, protecting your investment for decades.

Straight, solid structure pays back in durability and rental or resale appeal.

Serving Portland and Surrounding Areas

We serve Portland metro neighborhoods including Southeast Portland, Southwest, Hillsboro, Tigard, and Beaverton. Local knowledge of zoning, building inspector practices, and material suppliers keeps projects efficient.

Our team has built ADUs in neighborhoods across Portland from the Pearl District to Eastmoreland, and new construction homes from Bend to the Willamette Valley. We understand local lot constraints, weather patterns, and permitting pace.

How Much Does ADU Construction Cost?

ADU construction cost in Portland varies by size, finishes, site conditions, and whether you handle permits separately. A full turnkey build typically ranges from mid-five figures to six figures depending on square footage and finish level.

We recommend scheduling a site walk and detailed estimate conversation. We'll outline the scope, timeline, and costs for your specific project without hidden fees.

Frequently Asked Questions

Common questions about ADU construction in Portland.

How long does ADU construction take in Portland?

Permit review typically takes 2–6 weeks. Construction itself runs 3–6 months depending on size, weather, and material availability. Full timeline from permit application to occupancy is usually 5–8 months.

Do you handle ADU permits and plan submissions?

We manage permit coordination with the City of Portland. If you have plans, we ensure they meet code before submission. We also connect you with architects or plan services if you need design support.

Can you build an ADU on a narrow or sloped lot?

Yes. We've built ADUs on tight Portland lots with challenging slopes. Costs and timeline may increase slightly for foundation work and retaining walls, but tight sites are manageable with experienced framing and planning.

What is included in a full-service ADU build?

Full-service includes site prep, foundation, framing, electrical, plumbing, HVAC rough-in and finish, drywall, flooring, cabinets, fixtures, and all labor through certificate of occupancy. We coordinate inspections and manage the entire process.
