ADU construction

Build useful living space on the property you already own.

Dominion helps homeowners evaluate feasibility, plans, budget, permitting, and construction for ADUs in Oregon communities where local rules support added housing.

ADU planning and construction priorities

Start with feasibility

The first discussion should cover property location, zoning, whether plans already exist, financing readiness, utility questions, and whether an off-the-shelf plan could work.

Design and pre-construction

For homeowners who need design help, Dominion can guide a pre-construction contract to develop plans, criteria, elevations, budget assumptions, and permit-ready scope.

Permits and build management

Dominion can coordinate permitting assistance, subcontractors, vendors, schedule, warranty expectations, and communication through the build.

Oregon ADU context

Local rules can be ADU-friendly, but every property still needs review.

The site should frame ADU planning as practical and feasible in many Oregon communities while avoiding legal or lending guarantees. City or county zoning, utility capacity, plans, financing, and permits still need project-specific confirmation.

Salem permit planning

Use Salem ADU rules and ready-build plans as early feasibility inputs.

The City of Salem says ADUs are treated as a special use when they meet the applicable standards, but a building permit is still required. Salem also notes that off-street parking spaces are not required for ADUs.

For some detached ADUs under 600 square feet, Salem offers ready-build plans that can be used with the current building permit process. Dominion should review whether those plans fit the property, scope, utilities, and homeowner goals before assuming they are the right path.
