WebFetch succeeded directly; confirmed 3 named plan sets. Distinct from the County of Sacramento row (unincorporated area, different plan names/count) — verified these are two genuinely separate agencies/programs, not a duplicate. Adversarially re-verified 2026-07-31: independent re-fetch confirmed all 3 plans; also confirmed this is a genuinely separate program from the County of Sacramento's (different agency, different site, different plan names) — not a duplicate.

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 Sacramento’s plans as part of its own program instead of designing new ones — see the full statewide catalog for more options.
