Q: Do you also build ADUs? What's the difference between a home addition and an ADU?

Yes, we build both. A home addition expands your existing house — adding rooms, square footage, or features. An ADU (Accessory Dwelling Unit) is a separate self-contained dwelling on the same property, with its own kitchen, bathroom, and entrance. ADUs follow specific Clackamas County regulations. If you're not sure which fits your goals, we'll walk you through both options at the free estimate.

Q: Can Gencon work on condos or townhomes?

Yes. As a condo renovation contractor, we work within HOA requirements, building rules, and shared-wall constraints. From single-room interior remodels to full unit renovations, our team handles condo and townhome projects throughout Clackamas County and the Portland metro area.

What types of home additions does Gencon build?

Our home addition contractors build garage additions and garage conversions, sunrooms and backyard additions, full second-story additions, deck additions and deck replacements, staircase renovations, fireplace remodels, and full interior remodeling for condos and townhomes. If you need it added, expanded, or rebuilt — we can scope it.

How long does a home addition take?

A small interior addition or deck replacement can be completed in 3–6 weeks. A garage conversion typically takes 8–12 weeks. A full second-story or large room addition generally runs 4–6 months from permits through final walkthrough. Project manager Alex coordinates every trade so your timeline stays predictable.

Do you handle both garage additions and garage conversions?

Yes. As experienced garage remodel contractors, we build new attached and detached garage additions, and we convert existing garages into livable space — home offices, gyms, guest suites, or studios. We handle the framing, insulation, electrical, HVAC, and finishes so the converted space feels like it was always part of the house.

Can you build a sunroom or backyard addition?

Absolutely. Backyard remodels, sunrooms, screened porches, and outdoor living additions are some of our most-requested projects. We design them to match your existing home architecture so the addition looks intentional — not bolted on.

An ADU (Accessory Dwelling Unit) is a separate self-contained dwelling on the same property, with its own kitchen, bathroom, and entrance. ADUs follow specific Clackamas County regulations. Not sure which fits your goals? We'll walk you through both options at the free estimate. Learn more about ADU construction.
