Accessory Dwelling Units: Case Study

Accessory dwelling units (ADUs) — also referred to
as accessory apartments, second units, or granny flats
— are additional living quarters on single-family lots that
are independent of the primary dwelling unit. The separate
living spaces are equipped with kitchen and bathroom facilities,
and can be either attached or detached
from the main residence.

This case study explores how the adoption of ordinances,
with reduced regulatory restrictions to encourage ADUs,
can be advantageous for communities. Following an
explanation of the various types of ADUs and their benefits,
this case study provides examples of municipalities
with successful ADU legislation and programs.
