Cal. Civ. Code § 17970.7
California Health and Safety Code
Operative Text
(a) By January 1, 2025, local enforcement agencies shall develop policies and procedures for inspecting a building with multiple units if an inspector or code enforcement officer has determined that a unit is substandard pursuant to Section 17920.3, or is in violation of Section 17920.10, and the inspector or code enforcement officer determines that the defects or violations have the potential to affect other units of the building. (b) The policies and procedures developed pursuant to subdivision (a) shall meet all of the following requirements: (1) Include criteria that inspectors or code enforcement officers shall use to determine if the substandard condition could reasonably affect other units, taking into account factors, including, but not limited to, the building type, age, size, type of construction, cause of the substandard condition, and history of violations. (2) Require inspectors or code enforcement officers to reasonably attempt to inspect additional units at the property, including at least units adjacent to, above, and below the unit in which the defect or violation was found, consistent with existing law and inspection practices. (3) Allow for the inspection of all of the units on the premises if severe, buildingwide defects or violations are found. (c) (1) Upon determining that a substandard condition in a unit could reasonably affect other units, the local enforcement agency shall provide the property owner with a notice or order to repair or abate within a reasonable time after the inspection is completed. (2) The local enforcement agency shall advise the owner or operator of each known violation and of each action required to remedy the violation and schedule a reinspection to verify correction of the violations.
California Health & Safety Code § 17970.7 requires local enforcement agencies to establish, by January 1, 2025, written policies for expanding inspections beyond a single substandard unit when conditions could reasonably spread to neighboring units. At minimum, inspectors must attempt to examine units adjacent to, above, and below the problem unit, and may inspect an entire building if widespread defects are found. When a potentially spreading violation is confirmed, the agency must notify the property owner with a repair or abatement order and schedule a follow-up reinspection to verify corrections.
Plain English — not legal advice.
Under Cal. Health & Safety Code § 17970.7, a compliant property owner generally responds promptly to any notice or order issued after an expanded inspection, addresses each violation identified by the enforcement agency, and cooperates with the scheduled reinspection. Because a single substandard unit can trigger inspections of adjacent, above, and below units—or even the entire building—operators typically maintain proactive maintenance programs that reduce the likelihood of conditions spreading across units. Keeping clear records of repairs and communications with the local enforcement agency supports a documented history of compliance.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Cal. Health & Safety Code § 17970.7 gives tenants an interest in knowing that a substandard condition found in one unit can legally trigger inspections of neighboring units, including those above, below, and beside the affected unit. If a tenant believes their unit may be affected by conditions found elsewhere in the building, they can contact their local code enforcement or housing department to inquire whether an expanded inspection has been initiated under this provision. Tenant-rights organizations and local rent boards can also help residents understand how inspection findings and resulting repair orders may relate to their housing conditions.
