Editor's note— Ord. No. 3658, § II(exh. A), adopted Nov. 15, 2016, amended Ch. 19.20 in its entirety to read as herein set out. Former Ch. 19.20, §§ 19.20.010—19.20.070, pertained to similar subject matter, and derived from Ord. No. 3619, § II(exh. A, § III), 2014.

Express finding—Pursuant to California Health and Safety Code Section 17958.2(a), the Marin County Board of Supervisors hereby finds the application of regulations adopted by the California Department of Housing and Community Development for limited density owner-built rural dwellings, which are codified in the 2022 edition of Article 8 (commencing with Section 74) of Subchapter 1 of Chapter 1 of Title 25 of the California Code of Regulations, is reasonably necessary in rural portions of the unincorporated county of Marin, where local conditions, such as lack of readily available district water, sewer or utility power connections, exist to the extent it would exclude participation in the normal permit process and create an unreasonable burden to the property owner to comply with prescriptive building and development requirements, which are codified in the 2022 California Building Standards Code (Title 24 of the California Code of Regulations); (b) the Marin County Board of Supervisors also finds the following changes or modifications to the provisions contained in the 2022 edition of Article 8 (commencing with Section 74) of Subchapter 1 of Chapter 1 of Title 25 of the California Code of Regulations, and which are codified in Chapter 19.20, of Title 19 of Marin County Code are reasonably necessary to remove conflicting administrative provisions and integrate the requirements of this chapter into Marin County Code, insofar as the substantive application of these provisions is consistent with those contained within the 2022 edition of Article 8 (commencing with Section 74) of Subchapter 1 of Chapter 1 of Title 25 of the California Code of Regulations, as set forth in this chapter. (Amended by Ord. No. 3777, § II, 2022)
