Frequently asked in Los Angeles
What makes a detached ADU different from an attached one in Los Angeles?
In Los Angeles, a detached accessory dwelling unit is a completely separate structure on your property, like a backyard cottage. An attached ADU, on the other hand, is built as part of your existing home, sharing a wall. Detached units often provide more privacy and can be designed with their own distinct feel. The permitting process and some zoning rules might differ slightly between the two types. Talking to a local pro can clarify which option best suits your specific needs and property.
Are there any grants available for building an ADU in Los Angeles?
Currently, there aren't widespread direct ADU grants specifically for homeowners in Los Angeles. However, some programs might offer low-interest loans or financing assistance for ADU construction. The availability and specifics of these programs can change. It's best to ask the specialists you speak with about any potential financing options they are aware of.

How does a modular ADU compare to a site-built one in Los Angeles?
