CA AB2666

Authorizes development of "small home lot developments" in multifamily zones that meet specified criteria, allowing single-family housing units on individual fee-simple lots while maintaining minimum general plan density.

Requires small home lot developments to be located on parcels no larger than 5 acres, substantially surrounded by qualified urban uses, zoned for multifamily residential use, and consist of units with 1,600 net habitable square feet or less.

Exempts small home lot developments from most Subdivision Map Act requirements, though developers must submit a map meeting Section 66434 standards without requiring discretionary approval or public hearings.

Prohibits local agencies from imposing setback requirements between units, minimum lot sizes, or parking requirements exceeding 0.5 spaces per bedroom for developments within one-half mile of major transit stops.

Prohibits development if it would require demolition or alteration of affordable housing subject to covenants or rent control, housing occupied by tenants within seven years, or properties where owners exercised withdrawal rights under Chapter 12.75 within 15 years.
