What’s posted
The Building Division page posts one city-developed pre-approved ADU plan set ('ADU Plans and Specifications', the City of Atwater Pre-Reviewed Accessory Dwelling Unit Program PDF) together with Resolution No. 3472-24 (adopted 7/8/2024) approving the plans and specifications and initiating the ADU program.
Gap from a fully compliant program: Only a single city plan set is posted; no third-party submission process or applicant contact listing was found on the page.

Adversarially re-verified 2026-07-30: Building Division page re-fetched (still links 'ADU (Plans and Specifications)' and Resolution 3472-24); the 14.9MB plan-set PDF was downloaded in full and text-extracted with pdftotext - it is a complete 'CITY OF ATWATER ACCESSORY DWELLING UNIT PROGRAM' construction set (sheet indexes, floor plans, four elevations each) containing FOUR designs: 375, 550, 743, and 908 sq ft. plansCount updated 1 -> 4 accordingly.
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 Atwater’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).
