Benefits of Building an 800 Sq Ft ADU

Building an 800 sq ft ADU allows for efficient, independent living space while maximizing property use. As a statewide exemption ADU, units up to 800 sq ft must be allowed by California state ADU laws in all municipalities, as long as they meet ADU setback requirements. This size is ideal for adding value without exceeding local size limits.

Key Benefits and Cost Considerations:

• Compact Yet Spacious: With three bedrooms in an 800 sq ft footprint, this layout offers a practical solution for family or rental use.
• Cost-Effective for Maximum Space: For an ideal lot for an ADU, this unit can be completed for under $400K. However, it’s important to keep in mind site conditions such as slope or being on septic can impact total cost.
