However, if the ADU is detached and higher than 16 feet, it's allowed to have two-story ADUs.

What ADU types are allowed to build in Monterey Park?

Monterey Park offers several options for adding an ADU to your property:

  • Converted ADU: Converting spaces like garages, sheds, or storage areas into fully functional living units with amenities such as a kitchen and bathroom.

Homeowners can choose to either build a new ADU or convert an existing structure. Converting areas like garages or sheds may allow you to bypass certain zoning regulations, such as setbacks or height limits, and may permit small additions. However, renovating older structures could uncover unexpected issues that increase costs.
