Lot Splits. Urban Infill. Smarter Housing Solutions.

With California Senate Bill 9 (SB9), homeowners and developers can now build additional housing units or split their lots in previously single-family-only zones. At Aventiq Development Group, we specialize in SB9-compliant construction that transforms underused land into valuable, livable spaces—without the headaches of navigating city red tape alone.

What Is SB9?

SB9 is a California state law that allows eligible property owners to:

  • Split single-family lots into two parcels
  • Build up to 2 units per lot (4 total after split)
  • Bypass traditional rezoning restrictions
