Cal. Civ. Code § 460.700

(A) Responsibilities Generally. Pursuant to M.G.L. c. 111, §§ 194 and 198, local code enforcement
            agencies have the responsibility for making inspections of residential premises and other buildings which
            children utilize, and for enforcing the lead poisoning prevention laws, consistent with their sanitary code
            inspection and enforcement responsibilities under M.G.L. c. 111, §§ 127A through 127K.

            (B) Inspection Responsibility. A local code enforcement agency must inspect for lead paint whenever
            it receives a signed parental request for a lead inspection from an occupant or conducts an inspection
            for violations of the State Sanitary Code in a dwelling unit or residential premises constructed before
            1978, where a child younger than six years old resides. If the inspector is not certain whether or not
            a residence was constructed before 1978, the inspector shall check the relevant building permit at the
            city or town building department. If the inspector verifies that the dwelling was constructed in 1978
            or later, the inspector shall nevertheless determine whether any other structures within the same lot line
            were constructed before 1978, and if so, inspect them for lead paint. The obligation to inspect for lead
            paint must be fulfilled in one of the following two ways:
                 (1) A lead inspection shall be conducted at the time of the Sanitary Code inspection, or the
                 person conducting the Sanitary Code inspection shall ensure that a separate lead inspection by a
                 code enforcement lead inspector is conducted within the timelines specified in the Sanitary Code;
                 or
                 (2) In lieu of a complete lead inspection by a code enforcement inspector, the lead determination
                 enforcement procedure may be followed at the time of the Sanitary Code inspection and in all
                 circumstances covered by 105 CMR 460.710, except 105 CMR 460.710(A). A lead
                 determination report format approved by the Director shall be used to record test results. The lead
                 determination enforcement procedure shall be performed in accordance with guidance approved
                 by the Director. If the lead determination enforcement procedure identifies at least one surface with
                 a lead violation, the code enforcement agency shall issue an Order to Correct Violation(s) in
                 accordance with the procedures set out in 105 CMR 460.750(B), stating the enforcement
                 deadlines set out in 105 CMR 460.751(C), or in post-compliance cases, the deadlines set out in
                 105 CMR 460.760(E). Said Order to Correct Violation(s) shall be enforced through judicial
                 proceedings, in accordance with 105 CMR 460.800.

            (C) Emergency Matters. Violations of M.G.L. c. 111, §§ 196 and 197 produce immediate danger
            of lead poisoning and constitute emergency matters pursuant to M.G.L. c. 111, § 198 and the State
            Sanitary Code. Local code enforcement agencies shall treat them as emergency matters, giving such
            violations preference over all other violations, except other emergency matters, and shall follow the time
            limitations in 105 CMR 460.750, 460.751 and 460.800.
