SB-684 streamlines the approval process for small housing projects in San Diego, even in high-risk CEQA zones. However, strict environmental and safety regulations apply to ensure new developments are both resilient and compliant with state standards.

How SB-684 Works in High-Risk CEQA Zones


// Property & Lot Requirements
· SB-684 applies to properties up to 5 acres.
· Allows 2 to 10 residential units, each up to 1,750 sq. ft.
· A maximum of 10 lots per project, with each lot at least 600 sq. ft.

// Fire & Earthquake Safety
· No building allowed in Very High Fire Severity Zones, as designated by state fire maps or the Department of Forestry and Fire Protection.
· In earthquake fault zones, construction is restricted unless the project meets strict seismic safety standards.

// Flood Zone Restrictions
· Development in flood zones must follow floodplain management and federal flood control regulations.
· Projects in floodways require certification to ensure they don’t increase flood risks.


How SB-684 Benefits Real Estate Agents and Investors

If projects meet environmental safety standards, SB-684 still can create new development and sales opportunities in areas were zoning once restricted growth. More units mean more listings, more transactions, and higher returns. Agents and investors who understand these regulations can capitalize on small-lot development and turn overlooked properties into profitable projects.
