Premium Accessory Dwelling Units (ADUs) and Tiny Homes

An ADU (Accessory Dwelling Unit) is a secondary housing unit located on the same lot as a primary residence. It can be attached, detached, above a garage, or a converted interior space like a basement.

Costs vary widely based on size, design, finishes, and site conditions, but most ADUs range from $100,000–$350,000. Permitting, utilities, and foundation work also impact price.

Yes, nearly all municipalities require building permits and zoning approvals for ADUs. Requirements can include setbacks, maximum square footage, parking rules, and utility connections.

Typical timelines run 6–12 months from design to final inspection. Factors include permitting speed, design complexity, and contractor availability.
