Civ. Code 1962 requires a residential landlord to give the tenant notice of the name, phone number and street address of each owner and manager of the premises and to update that information if it changes, as by sale of the property to a new owner. The statute forbids service of a notice to quit or commencement of an unlawful detainer action during any period of non-compliance with the statute. This decision holds that strict compliance with the statute is required. Substantial compliance does not suffice. So even though the tenant supposedly knew who the manager was, having paid her rent before, failure to serve an updated notice after a change in ownership constituted a complete bar to the new owner’s unlawful detainer action.
