Rancho Cucamonga, CA Rental Property Rules: Rental Registration (2026)

Unlike some Southern California cities that require annual rental unit registration and proactive inspections, Rancho Cucamonga has not adopted a mandatory rental housing registry or periodic inspection ordinance. Landlords operating rental property as a business may be required to obtain a Rancho Cucamonga business license through the Finance Department depending on the number of units and structure; most owners of one to three rental units are not required to register as a business, but commercial rental operators and property management companies generally must hold a city business license under Municipal Code Title 5. All rentals must still comply with California Civil Code Section 1941.1 habitability standards, the state AB 1482 disclosure notice for covered units under Civil Code 1946.2(f), lead-paint disclosures for pre-1978 units, and the Bed Bug Disclosure requirement under Civil Code 1954.603. Tenants with habitability complaints can contact San Bernardino County Department of Public Health or Rancho Cucamonga Code Enforcement, which inspects on a complaint-driven basis rather than proactively. Short-term rentals have separate permitting under the Municipal Code and are not part of the long-term rental framework.
