Why Choose An ADU?

Excellent Investment

Offering a better ROI than most residential real estate. Since you already own the land and SDC beforehand, costs are greatly reduced.

Long Term Usage

ADU’s are great for multigenerational living. Keep your loved ones close to home, without sharing yours.

Versatile Solution

ADUs are versatile and can be used as long-term (as a consistent rental income) or short-term rentals (30-day or VRBO vacation rental).

In Demand

ADUs fulfill the demand and desire for higher-density residential development in a rapidly-growing urban area.

Frequently Asked Questions

What are ADUs (Accessory Dwelling Units)?

Accessory dwelling units (ADUs) may also be known as “granny flats,” “granny pods,” or “mother-in-law apartments.” ADUs are add-on living quarters that provide room for the current property to house additional people comfortably. ADU’s are not shared living spaces — they are separate living spaces that include a kitchen and bathroom. Some ADUs are attached to the main home, while others are separated structurally from the primary dwelling unit.

What are the benefits of ADU’s?

Benefits of ADU’s to Property Owners

  • ADU’s can provide extra income from the same property
  • ADU’s are a less expensive way to build
  • ADU’s can pull from an already existent infrastructure
  • ADU’s can blend in with the current property to maintain character
  • ADU’s help property owners get more value from their current holdings

Community Benefits of ADU’s

  • ADU’s add to the housing supply to relieve shortages
  • ADU’s can be an affordable housing option for many who couldn’t otherwise afford a home
  • ADU’s allow families to take better care of elderly or disabled loved ones
  • ADU’s can be perfect for young people or single people to lower the cost of living
  • ADU’s can be a stop-gap to urban sprawl and zone changes

What types of Accessory Dwelling Units are there?

ADUs can be classified into three categories, depending on their relation to the main home: interior, attached, and detached.

  • Interior ADUs are located within the primary dwelling. Normally, that calls for converting a basement or attic into living quarters.
  • Attached ADUs are built alongside the main home. Many owners choose to add an ADU above the garage, rather than add on to the side or rear of the primary dwelling place.
  • Detached ADUs are structures completely separate from the main home. They can be built over a detached garage or shop, or they can be located on a different part of the lot, depending on space available.

What are the Regulations Concerning ADUs?

Every locality manages its own building and planning. Once you’ve decided where you want an ADU built, check with the local governing body to determine whether ADUs are allowed and which regulations affect the construction.
