Building an accessory dwelling unit (ADU) is an excellent way for homeowners to add more space, increase property value, and generate additional rental income. Before starting, it's important to evaluate if your property is ADU ready by considering zoning laws and space availability.
Whether you’re looking to create a detached ADU, an attached ADU, or convert an existing garage into a garage conversion ADU, working with a reliable ADU builder is essential to ensure a smooth and successful ADU project. Assessing your property's potential for an ADU can help you maximize benefits like increased property value and rental income.

An accessory dwelling unit, often called an ADU, granny flat, guest house, or accessory dwelling unit (ADU), is a secondary living space on a property that provides independent living quarters. ADUs are built on the same lot as the primary residence, serving as secondary structures to the main home. They can be attached to the main house or exist as detached ADUs, which are standalone backyard homes that offer privacy and flexibility. Accessory dwelling units ADUs offer several advantages, including more living space for extended family, a rental unit for additional income, or a private guest house.
The size and design of an ADU can vary greatly depending on local regulations, zoning laws, and the property’s potential. Selecting the right ADU size is important, as it impacts both construction costs and how well the space meets your needs.
