What’s posted
City's ADU page has a Pre-Approved Plans section linking to freely downloadable LA County Building & Safety PDFs (garage conversion/JADU standard notes and details), no login/paywall.
Gap from a fully compliant program: Scope limited to garage conversion/JADU, not a multi-option new-construction catalog; hosted on LA County's domain, not the city's own, though AB 1332 §(a)(5) explicitly permits admitting another agency's preapproved plans.

Independently re-verified 2026-08-04: confirmed free, no-login PDFs linked directly from the city's own ADU page; scope caveat preserved.
Any other agency can adopt these plans
Cal. Gov. Code § 65852.27, added by Stats. 2023, ch. 759, amended by Stats. 2024, ch. 7 (SB 477) (§ 65852.27(a)(5)) lets any California local agency admit into its own program plans “A local agency may also admit the following accessory dwelling unit plans into the program: (A) Plans that have been developed and preapproved by the local agency. (B) Plans that have been preapproved by other agencies within the state.” A city or county without a preapproval program of its own can post City of Westlake Village’s plans as part of its own program instead of designing new ones — see the full statewide catalog for more options.
We build and maintain the program page, the plan library and the required third-party submission path for agencies that want to stand this up: $1,950 setup + $3,600/year (year one all-in $5,550).
