Talk over your lot and your ADU idea — (000) 000-0000A Small House on Your Lot
An accessory dwelling unit fits a household's daily needs into a compact footprint: its own door, somewhere to cook, a bathroom and a bedroom. It could be a backyard cottage, an attached suite or a garage given a second life.
Zoning answers the first questions: whether your lot qualifies, the largest size allowed, the setbacks, and whether the unit may be rented. With those settled, most of the construction happens away from your house.
What an ADU Involves
-
The structure
Detached units start with fresh footings and framing; garage conversions get the existing structure reinforced, insulated and split into rooms.
-
Utility connections
Water, sewer and power brought from the main house or the street. How far those lines travel is one of the biggest swings in cost.
-
Everything inside
Kitchen cabinets and appliance hookups, a full bathroom, a bedroom and living space, insulated, wired, plumbed and finished like any other home.
Order of Work
-
Zoning comes first
County or city zoning sets lot eligibility, maximum size, setbacks and rental use. We get those answers before anything is priced.
-
Utilities and foundation
Water, sewer and power are trenched in from the house or street, and a foundation goes in, or an existing garage slab is checked and reused.
-
Build and finish
Framing, insulation, the kitchen, the bathroom and finishes follow, with deliveries and debris staged so your driveway and yard stay usable.
ADU Questions
Can I rent the unit out?
Possibly, but confirm it before counting on the income. County and city rules decide whether a unit may be rented and under what conditions, and those rules differ from one place to the next.
Does converting a garage cost less than building new?
Usually, since the slab and walls already exist. A detached unit costs more but gives more privacy and doesn't take away your parking or storage.
Got Space Out Back?
Say where the unit might go, who it's meant for and whether rental income figures into it. We'll start from there.
