An accessory dwelling unit (ADU) is a second, smaller home on a lot that already has one: a detached cottage, a garage or outbuilding conversion, or a unit attached to the main house.
What can be built depends on the property. Zoning, setbacks, height, utilities, stormwater and any HOA covenants all matter, and requirements differ by city and county. We start with a property-specific feasibility check, then handle planning, permits and construction.
People build ADUs for family, rental income or housing during a renovation. The reason shapes what makes sense to build, so it is the first thing we ask.
