Fetched the city's own pre-approved-adu-plans page (www.santa-ana.org redirects to santa-ana.gov). Confirmed named/downloadable plan catalog with ZIP file links per plan. Adversarially re-verified 2026-08-06 by an independent re-fetch agent: Page lists 10 named plans across Studio (3), One Bedroom (6), and Two Bedroom (1) categories, each downloadable as a ZIP of submittal documents hosted on santa-ana.gov, credited to Design Path Studio and James Gartner & Associates but files served by the city.
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 Santa Ana’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).
