Eastvale, CA Accessory Structures: Tiny Homes (2026)

05, the Residential Code, most recently rewritten by Ordinance No. 25-15 (adopted November 12, 2025, effective January 1, 2026). Sec. " Naming Appendix BB specifically means the city has opted into the state's tiny-home construction standard rather than leaving it unadopted, which some California jurisdictions do; without that express reference, Appendix BB would not apply locally. Because Appendix BB is folded into the adopted Residential Code, a tiny home built under it goes through the same permit and inspection track as any other detached dwelling: an application to the Building Official under Sec.

050, plan review and construction documents under Sec. 070, and the staged inspections in Sec. 110, ending with a certificate of occupancy under Sec. 120. A copy of the adopted 2025 California Residential Code, including Appendix BB, is on file with the Building and Safety Division and the Office of the City Clerk for anyone to review before designing a project. The city's Residential Code chapter also carries forward exceptions for structures that comply with fire sprinkler standards, covering live/work units, small owner-occupied lodging houses and small licensed care facilities, under Sec. 010(d)(2).
