Can I build an ADU on the side of my house or in the front yard?

Attached ADU – An attached ADU can be built on any side of the house, but all required setbacks apply.

Detached ADU – A detached ADU is generally constructed behind the primary residence, however due to existing conditions and site constraints, they may be permitted in other areas provided all development standards are met.
