Cal. Civ. Code § 17970.3
California Health and Safety Code
Operative Text
(a) This section shall only apply to both of the following: (1) A new residential construction of a building that contains at least 1 unit, but no more than 10 units, contains only residential units, and has no floors used for human occupancy located more than 40 feet above ground level. (2) A residential addition to an existing building that contains one to nine dwelling units, inclusive, contains only residential units, and has no floors used for human occupancy located more than 40 feet above ground level, for the purpose of adding new residential units to the existing building, not to exceed 10 total units in the building as proposed to be constructed. (b) Within 10 business days of receiving a notice of the completion of the permitted work authorized by a building permit issued for a project subject to this section, the building department of every city or county shall conduct an inspection of the permitted work. (c) If a building department of a city or county fails to meet the time limit in this section, it shall be in violation of Section 65589.5 of the Government Code.
California Health & Safety Code § 17970.3 establishes a mandatory inspection timeline for certain small residential construction projects. It applies to new residential buildings of one to ten units, and to additions that bring an existing one-to-nine-unit building up to a maximum of ten units, provided no occupied floor exceeds 40 feet above ground. Once a building department receives notice that permitted work on a qualifying project is complete, it must conduct an inspection within 10 business days. A building department that misses this deadline is deemed in violation of Government Code § 65589.5.
Plain English — not legal advice.
For property owners and developers undertaking projects covered by § 17970.3 — small residential builds or additions within the one-to-ten-unit and 40-foot-height thresholds — the practical implication is that the local building department is legally obligated to inspect within 10 business days of receiving a completion notice. Operators managing these projects typically document the date they submit their completion notice and track the 10-business-day window to ensure the inspection occurs on schedule. If the department does not respond within that period, the failure carries a statutory consequence under Government Code § 65589.5, which may be relevant when pursuing project closeout or certificate of occupancy timelines.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
For tenants moving into or living in small residential buildings that were newly constructed or expanded under a permit subject to § 17970.3, this provision means the local building department was required to inspect the completed work within 10 business days of receiving a completion notice. If that inspection did not occur within the required window, the building department was in violation of Government Code § 65589.5. Tenants who have concerns about whether required inspections were completed on a qualifying building can request public records from the local building department, contact a local tenant-rights organization, or raise the issue with the relevant city or county housing authority.
