What’s posted

The County's Pre-Approved ADU Program page posts one completed plan, 'North Fork Cottage,' a 600 sq ft detached ADU plan set owned by the County and offered to the public for free with a direct download link.

Gap from a fully compliant program: Beyond this one County-owned plan, the vendor-submission track for additional designer plans has not yet added further listings.

Fetched the program page directly and confirmed the North Fork Cottage plan set is posted with a working download link, distinct from the still-developing vendor-application section. Adversarially re-verified 2026-08-06 by an independent re-fetch agent: Page names one plan, 'North Fork Cottage' (600sf detached ADU), owned by the County and free to the public, with a direct download link (hosted on Google Drive but linked from the county's own page).

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