§ 66310

Government Code §§ 66310–66342 — Accessory Dwelling Unit and Junior ADU Law · 2026 edition · updated 2026-07-29 · California

  1. The Legislature finds and declares all of the following:

(a) Accessory dwelling units are a valuable form of housing in California.

(b) Accessory dwelling units provide housing for family members, students, the elderly, in-home health care providers, the disabled, and others, at below market prices within existing neighborhoods.

(c) Homeowners who create accessory dwelling units benefit from added income, and an increased sense of security.

(d) Allowing accessory dwelling units in single-family or multifamily residential zones provides additional rental housing stock in California.

(e) California faces a severe housing crisis.

(f) The state is falling far short of meeting current and future housing demand with serious consequences for the state’s economy, our ability to build green infill consistent with state greenhouse gas reduction goals, and the well-being of our citizens, particularly lower and middle-income earners.

(g) Accessory dwelling units offer lower cost housing to meet the needs of existing and future residents within existing neighborhoods, while respecting architectural character.

(h) Accessory dwelling units are, therefore, an essential component of California’s housing supply.

(Added by Stats. 2024, Ch. 7, Sec. 20. (SB 477) Effective March 25, 2024.)
