Zoning Comes First

Whether you can build an ADU, how big it can be and whether it may be rented depend on city or county zoning, and those rules differ from one jurisdiction to the next. That question gets answered before anything else.

Once your lot qualifies, the scope breaks the unit into its parts so you can compare a garage conversion with a new cottage on real numbers.

What an ADU Scope Lists

  • Foundation or slab

    A new foundation for a detached unit, or an assessment of the existing slab when a garage is converted into living space.

  • Utility connections

    Trenching and hookups for water, sewer and power, with the distance to each connection point priced as its own item on the scope.

  • Structure and shell

    Framing, insulation, windows and exterior finish for a new unit, or new walls, insulation and an entry door for a conversion.

  • Kitchen, bath and finishes

    A compact kitchen, a full bathroom and the interior surfaces, fixtures and paint, each named on the scope with its price.

Questions to Settle Early

  • Who will live there

    A unit for a relative and a rental can need different things, such as separate meters or a private entrance. Knowing the use up front shapes the scope.

  • Conversion or new build

    A garage conversion builds on what is already standing, which tends to keep cost lower. A freestanding cottage offers more privacy and separation, but every part of it is new construction.

  • Parking and access

    Some jurisdictions require parking for an ADU, and construction access to the backyard affects how materials are delivered and priced.

ADU Questions

What does the build schedule look like for an ADU?

Garage conversions tend to move faster since the shell already stands. A new detached unit usually runs several months after approval, with inspections at each stage of the build.

Is renting the unit allowed?

Zoning decides it. Certain jurisdictions permit ADU rentals, others restrict them, and owner-occupancy rules may apply. Those rules get confirmed before any construction plan.

Weighing a Second Unit?

Describe the lot, the person you picture living there and whether a garage conversion or a new structure appeals more. We will go over what each path involves.
