Create an independent living space with compliant construction planning.

Accessory dwelling units and similar secondary residences offer flexibility for families and property owners. H&M BUILDERS USA, INC. assists in evaluating lot conditions, zoning considerations, and structural requirements prior to development. Whether detached or attached, these units are planned to maximize space efficiency and functional comfort. Careful coordination ensures alignment with municipal regulations and property guidelines. Each project is approached with clarity to support multi-generational or rental living solutions.

Below are the most common types and how each serves different residential needs:

  • Casita

A casita is a detached, self-contained residential structure built on the same property as a primary home. It typically includes a bedroom, bathroom, and small living area, making it suitable for guest accommodations, extended family housing, or private workspace use. Casitas provide flexibility without altering the main residence layout.

  • ADU (Accessory Dwelling Unit)

An ADU is a secondary residential unit located on a single-family or multifamily lot. It contains essential living features such as a kitchen, bathroom, sleeping area, and separate entrance. ADUs can be detached, attached, or converted from existing structures like garages.

  • JDU (Junior Dwelling Unit)

A JDU is a smaller residential unit created within the walls of an existing primary home. It usually features a compact living area with an efficiency kitchen and may share certain utilities or bathroom access. JDUs are designed to maximize underutilized interior space without major structural expansion.

  • In-Law Unit

An in-law unit is a secondary living space intended to accommodate extended family members. It may be attached to or detached from the primary residence and includes essential living amenities for privacy and comfort. These units are designed to support independent living while remaining close to the main household.
