Why Hire a Professional ADU Contractor Near You?

An ADU is not a standard room addition or remodel. Its a fully independent structure or conversion that must meet strict building codes, zoning requirements, and utility standards. Local expertise matters.

• Understands your local city or county codes

• Can navigate permitting efficiently

A local ADU contractor offers responsiveness and insights that out-of-town or general contractors simply cant match.

Types of ADUs You Can Build

Before hiring a contractor, its helpful to know your options. There are four main types of ADUs:

1. Detached ADU A standalone structure built in the backyard or side yard

2. Attached ADU An addition connected to the primary home

3. Garage Conversion ADU Repurposing an existing garage into a livable unit

4. Junior ADU (JADU) A smaller unit (?500 sq. ft.) carved out within the existing home

Each comes with unique design, permitting, and construction considerations. An experienced ADU construction team will help you choose the best option based on your goals, lot size, and budget.

A site evaluation to check zoning rules, setbacks, easements, utility access, and structural constraints.

? Step 2: Design & Planning

Architectural designs are drafted and refined with your input. Contractors coordinate with engineers as needed.
