Gencon: ADU Contractors Serving Clackamas County

Gencon is a family-owned accessory dwelling unit construction company serving homeowners throughout Clackamas County, Oregon. Founded by brothers Max, Alex, and Oleg, the company combines hands-on craftsmanship with structured project management to deliver complete ADU builds — from compact in-law suites to fully detached backyard cottages.

Gencon operates as a design-first ADU builder. Every accessory dwelling unit they construct is intended to feel like a natural extension of the existing property — thoughtfully positioned, properly finished, and built to the same standard as the main home. Whether the goal is rental income, multigenerational living, or long-term property value, Gencon manages the entire process from initial design through final walkthrough.

Oregon's HB 2001 legislation significantly expanded ADU rights for homeowners, and Clackamas County has implemented those changes. This means more properties now qualify for ADU construction than before, making it a practical option for a wider range of homeowners.

ADU Types Gencon Builds

Gencon offers a range of ADU construction services to suit different property types, budgets, and goals:

1. Detached ADU (Backyard Cottage): A fully separate structure built from foundation through final finish. Detached accessory dwelling units are sited and designed to complement the existing home, and are commonly used for rental income or independent living.
2. Attached ADU: Connected to the main home but with its own entrance, kitchen, and living space. Attached ADUs add rentable square footage without the complexity of a full detached build.
3. Garage Conversion ADU: Gencon converts underused garages into fully permitted, livable dwelling units. This includes insulation, drywall, plumbing, electrical, and complete interior finishing — turning storage space into a functional rental unit.
4. In-Law Suite: Purpose-built for multigenerational living, these units are designed to provide comfortable, accessible space for family members who want independence without distance. Gencon's in-law suite construction is integrated thoughtfully with the existing home.
5. Backyard Cottage: A custom-built structure designed to function as a real home. Gencon approaches backyard ADU construction with the same design planning and craftsmanship applied to every other project type.
6. Junior ADU (JADU): A conversion of an existing bedroom, basement area, or attached space into a fully permitted dwelling unit within the home's existing footprint. JADUs are well-suited to properties with limited lot space or tighter budgets.

A garage conversion ADU typically takes 3–5 months from permit approval to move-in. A new detached ADU build generally runs 6–10 months, depending on design complexity, site conditions, and material selections.

How Gencon Manages the ADU Build Process

Gencon follows a structured five-step process for every ADU project in Clackamas County:

1. Free Property Consultation: One of the Gencon brothers visits the property, assesses the lot and existing structures, discusses ADU type options, and provides an estimate.
2. Design & Space Planning: A design plan is developed covering layout, exterior finish, interior materials, and utility connections — all finalized before construction begins.
3. Permits & Approvals: Alex, the project manager, handles all permit applications and coordinates directly with Clackamas County building officials to ensure full code compliance.
4. Site Prep & Foundation: For detached ADUs, site preparation, foundation work, and utility rough-ins — plumbing, electrical, and HVAC — are completed and inspected before framing begins.
5. Build, Finish & Walkthrough: Max leads the complete build through framing, MEP systems, insulation, drywall, and all finish work. The unit is not handed over until it meets the agreed standard.

Gencon delivers fully finished, move-in-ready units. This includes flooring, cabinetry, bathroom fixtures, kitchen, paint, and trim — not a structural shell requiring additional contractors to complete.

The team behind Gencon brings complementary experience to each project. Max has over 20 years of construction experience, including running Honest Quality Construction. Alex managed large multifamily projects across the US at Redwood Construction, bringing systematic coordination to each ADU build. This combination of craftsmanship and project management is central to how Gencon operates as an ADU contractor in Clackamas County.

ADUs built by Gencon are constructed to full residential building code, making them legally rentable in Oregon from day one. Clackamas County's rental market means a well-built ADU can generate meaningful monthly income, and properties with ADUs have consistently shown increased resale value in the local market.

Most residential properties in Clackamas County can accommodate at least one ADU under current Oregon law and local zoning codes. Gencon assesses each property individually to determine what is buildable given the specific lot, existing structures, and homeowner goals.
