Adversarially re-verified: performed two independent WebFetch calls to the same evidence URL. First fetch confirmed 4 downloadable plan PDFs hosted on gonzalesca.gov; second, separately-worded fetch re-confirmed the same 4 files (1A-, 2A-, 1B-, 2B-Plans, all on gonzalesca.gov) with no payment/login/vendor-contact prerequisite, explicitly noting Design Path Studio is credited as the plan designer but distribution/download happens directly through the city's own site. Bucket confirmed as 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 Gonzales’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).
