Cape Accessory Dwelling Unit: Exterior Attached Addition

Description of Conversion

Exterior Attached Additions can be more feasible when it comes to Cape style homes. The homeowner has a lot more freedom when it comes to parameters to build within. As long as the addition is within the zoning laws, the ADU isn’t limited by existing space. This allows for more flexibility to create a space that is ADA accessible while also allowing the ADU to be accessed from within the existing home.

• Space is less limited
• Don’t need to worry about fitting within a existing parameter

• Space to build is limited by local zoning

• New construction, from foundation to facade
