Different types of ADUs:

Garage conversion
Garage conversions provide a cost-effective solution for homeowners seeking to expand their living space without undergoing new construction, making them a popular choice for adding an ADU to a property. Depending on the garage’s configuration, it can be converted into either an attached or detached ADU. It’s important to note that the converted space will generally adhere to the garage’s original blueprints. Consequently, garage conversions are typically more affordable compared to constructing an entirely new unit from scratch.

Above a garage
While the concept of an accessory dwelling unit (ADU) above the garage might seem similar to a garage conversion, it often involves additional complexities. For example, most garages lack sufficient structural support to accommodate a second floor. In many cases, reinforcing the garage to bear the weight of an additional level can be quite costly. Consequently, many homeowners choose to demolish the existing garage and construct a new unit from scratch.

Detached new construction
Detached ADUs, also known as standalone ADUs, are accessory dwelling units that are separate structures from the primary residence. They are constructed as independent units on the same property but are not physically connected to the main house. Detached ADUs can take various forms, such as a small cottage, a converted garage, or a purpose-built structure. They offer greater privacy and separation from the main house, making them an attractive option for extended family members, guests, or as rental units.

Bump out
A bump-out ADU is an internal conversion of the main residence. The best way to imagine it is as an extension that shares a wall with the primary house. This ADU option is commonly chosen in cases where a garage is not available for conversion.

Attic conversion
An attic conversion refers to the process of transforming an attic space into a livable and functional accessory dwelling unit (ADU). It involves renovating and modifying the attic to meet the necessary building codes and requirements for residential occupancy. This conversion typically includes adding insulation, proper ventilation, windows, flooring, electrical wiring, and plumbing to create a self-contained living space within the attic. The attic ADU can serve as an additional dwelling unit for rental purposes

Interior ADUs
Interior ADUs, also known as internal ADUs, are accessory dwelling units that are located within the existing interior space of a primary residence. Rather than being separate structures or conversions of external spaces like garages or attics, interior ADUs are created by repurposing existing rooms or areas within the main house. This can include converting basements, unused rooms, or even dividing larger rooms into separate living spaces. Interior ADUs offer a convenient and space-efficient solution for adding additional housing units within the primary residence, allowing for multigenerational living, rental income, or flexible living arrangements. These units typically have their own entrance, kitchen, bathroom, and living area, ensuring privacy and independence for the occupants.
