About ADUs
Learn about Accessory Dwelling Units and their benefits
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. ADUs can be attached to the main house, detached, or created by converting existing space like a garage.
ADUs are becoming increasingly popular in Sacramento as they provide flexible housing options, additional income potential, and solutions for multi-generational living.
- •Rental Income: Generate additional monthly income by renting out the ADU
- •Multi-Generational Living: Provide independent living space for family members
- •Increased Property Value: ADUs typically increase overall property value
- •Flexibility: Use as home office, guest house, or rental unit
- •Tax Benefits: Potential tax advantages for rental income
Detached ADU
A standalone structure separate from the main house, offering complete privacy and independence.
Attached ADU
Connected to the main house but with a separate entrance, often more cost-effective to build.
Converted Garage ADU
An existing garage converted into living space, typically the most affordable ADU option.
Sacramento has streamlined ADU regulations to encourage their development. Key points include:
- • Maximum ADU size: 1,200 square feet or 50% of the main house (whichever is less)
- • Minimum lot size: Typically 5,000 square feet
- • Setback requirements: Vary by zoning district
- • Parking: May be required depending on location
- • Owner occupancy: May be required for the main house or ADU
Always consult with local planning departments and professionals for current regulations.
