Which Should You Choose?

  • You want a simpler, faster process
    • You're not planning immediate construction
      • You want maximum flexibility for future use
      • Choose SB-9 if

        • You plan to develop rental housing
          • You want to build duplexes or multiple units
            • You're committed to long-term housing development
              • You can navigate more complex requirements
              • Local Jurisdiction Considerations

                Each California city and county implements these laws differently. Some jurisdictions favor one approach over another, while some have specific local requirements that affect your choice.

                Financial Comparison

                While SB-9 has higher upfront costs, it may provide greater long-term returns through rental income. SB-684 offers quicker returns through increased property values with lower initial investment.

                Professional Consultation

                Given the complexity of both laws, professional consultation is essential. An experienced consultant can analyze your specific property, local regulations, and financial goals to recommend the best approach.

                The choice between SB-684 and SB-9 depends on your goals, timeline, budget, and local regulations. Both laws offer valuable opportunities for California property owners.
