What’s posted
Oakley's Pre-Approved ADUs page explicitly cites the state law requiring an online library of preapproved ADU designs and lists six free downloadable plan sets (375, 550, 743, 850, 990, 1200 sq ft) meeting 2025 CRC requirements, plus a private designer gallery.

Second independent WebFetch of the first plan PDF (DocumentCenter/View/1999, 375 sq ft plan) failed only because the file exceeded the 10MB fetch limit -- confirming it is a real, large, non-placeholder document at the documented URL on the city's own DocumentCenter. Confirmed posted.
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 Oakley’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).
