What is an interior conversion ADU
An interior conversion Accessory Dwelling Unit (ADU), also known as a Junior Accessory Dwelling Unit (JADU), involves converting part of an existing primary dwelling into a separate living unit. This could involve converting a basement, an attic, a garage, or even one or more rooms of a house. Like other types of ADUs, an interior conversion ADU is meant to be a completely independent living space with its own living area, kitchen, bathroom, and sleeping area.
Here are the typical requirements for creating an interior conversion ADU in Los Angeles. Please verify these with local planning officials or a planning professional for the most recent regulations:
- Zoning: The property must be zoned for residential use.
- Existing Primary Dwelling: There must be an existing primary dwelling on the property to be partially converted into an ADU.
- Size: The size of the ADU must not exceed 50% of the primary dwelling. The maximum size is typically up to 500 square feet for a JADU.
- Entrances: The ADU must have its own separate entrance from the primary dwelling. However, a JADU can share an entrance with the primary dwelling.
- Kitchen and Bathrooms: The ADU must have its own kitchen facilities, and can have its own bathroom or share one with the main dwelling. A full ADU must have its own bathroom, while a JADU can share a bathroom.
- Parking: If the ADU involves the conversion of a garage, the required parking for the main house must be replaced elsewhere on the lot. However, no additional parking is required for the ADU itself if it is within a half-mile of public transit.
- Owner Occupency: There is no owner-occupancy requirement for full ADUs, meaning the owner is not required to live in either the ADU or the primary dwelling. For JADUs, owner occupancy in the primary dwelling or the JADU is required.
- Utilities: The ADU must have proper utilities, which can either be shared with the main house or separate, depending on local regulations and the preferences of the owner.
- Building Code Compliance: The design and conversion of the ADU must comply with all local and state building codes.
Remember that these requirements are subject to change and can also vary depending on specific situations and locations. Always consult with local planning officials or a planning professional for the most accurate and up-to-date information.
