ADU & Garage Conversions in Elftman, CA

These options provide additional living space and can enhance property value, particularly for families, seniors, or rental purposes in an area where 98.1% of homes are small (studio to two-bedroom) units.
What Is an Accessory Dwelling Unit (ADU)?
An accessory dwelling unit (ADU) is a secondary housing unit on a single-family lot. It can be a separate structure or part of the main home, such as a basement or attic conversion. ADUs are ideal for multi-generational living or as rental units to generate extra income in a neighborhood where the average rental price is currently $4,457 (higher than 81.4% of California neighborhoods).
