Exploring the Different Types of Accessory Dwelling Units (ADUs)

As the world of home building evolves, Accessory Dwelling Units (ADUs) have emerged as a versatile and valuable addition to modern living spaces. These secondary housing units, also referred to as in-law suites or backyard cottages, offer a plethora of benefits from additional income streams to enhanced property value. In this blog post, learn about the different types of ADUs and the factors to consider when looking to add this type of home to your property.

What Are ADUs?

ADUs are self-contained residential units located on the same lot as a primary dwelling. They can be detached, attached, or even internal conversions of existing structures. ADUs serve various purposes including, providing housing for extended family members, generating rental income, or serving as a private home office or studio.

Types Of ADUs

Detached ADUs

Detached ADUs are standalone structures separate from the main house. They are often located in the backyard and can range from compact tiny homes to more sizable fully-equipped residences. This type of ADU is good for homeowners that have a lot of outdoor space and want to create a rental unit, guest house, or private residence for family members.

Pros:

  • Complete privacy and independence from the main dwelling.

  • Flexibility in design and layout.

  • Potential for increased property value.

Attached ADUs

Attached ADUs are extensions or additions built onto the existing primary residence. They share at least one wall with the main house but have a separate entrance and living quarters. This type of ADU is good for homeowners looking to add an in-law suite or rental unit without drastically altering their property.

Pros:

  • Generally lower construction costs compared to detached units.

  • Easier access to existing utilities and infrastructure.

  • Maintains some level of connection with the main house.

Garage Conversion ADUs

Garage Conversion ADUs involve transforming an existing garage into a livable space. This type of ADU makes use of pre-existing structures and can be a cost-effective way to add additional housing. This type of ADU is good for homeowners with unused or underutilized garages who want to create a compact living space for rental income or family use.

Pros:

  • Utilizes existing structures.

  • Typically faster to build and permit.

  • Preserves yard space for other uses.

Basement Conversion ADUs

Basement Conversion ADUs involve repurposing an existing basement into a separate living unit. This type of ADU maximizes the use of available space within the home and is good for homeowners with underutilized basements looking to create additional living space for family members or tenants.

Pros:

  • Cost-effective, utilizing existing square footage.

  • Minimal impact on the exterior appearance of the home.

  • Potentially faster to complete than new construction.

Internal ADUs

Internal ADUs are created by reconfiguring existing space within the primary home. For example, this could be converting a portion of the home into a separate unit. This type of ADU is good for homeowners looking to create a small, self-contained unit within their home for rental income or to accommodate family members.

Pros:

  • Cost-effective.

  • Minimal impact on the exterior of the home.

  • Can be completed relatively quickly.
