Cal. Civ. Code § 410-38-5-2
Inspection of contaminated property following decontamination
Operative Text
Sec. 2. (a) Before issuing a certificate of decontamination, the qualified inspector shall inspect the contaminated property for the chemicals listed in Table 1 that are determined to be present during the review of law enforcement reports and the assessment required by section 1(1) through 1(3) of this rule. (b) The qualified inspector shall use the sampling procedures in this rule. (c) Analysis for the contaminants listed in Table 1 must use: (1) Method 8270C; or (2) an equivalent method or practice. (d) The qualified inspector shall determine if the levels of chemicals listed in Table 1 that were identified during the initial assessment performed under section 1(3) of this rule are equal to or lower than the decontamination levels in Table 1. Table 1. Chemical Chemical Abstract Service Registry Number Final Decontamination Level Methamphetamine 7632-10-2 or 537-46-2 0.5 μg/100 cm2 Amphetamine 300-62-9 0.5 μg/100 cm2 Ephedrine 299-42-3 0.5 μg/100 cm2 Pseudoephedrine 90-82-4 0.5 μg/100 cm2 Methcathenone 112117-24-5 0.5 μg/100 cm2 Lysergic acid diethylamide (LSD) 50-37-3 0.5 μg/100 cm2 3,4-methylenedioxy-methamphetamine (MDMA) (Ecstasy) (No CAS number) 0.5 μg/100 cm2 Phencyclidine (PCP) 60124-79-0 0.5 μg/100 cm2 Gamma hydroxybutyrate (GHB) 591-81-1 0.5 μg/100 cm2 1 An alternate final decontamination level may be used for a specific contaminated property if that alternate level is based on the levels of chemicals found during the initial assessment required by section 1 of this rule and the planned reuse of the property is at least as protective of human health as the corresponding final decontamination level and is accepted by the commissioner. (e) All sample analysis must be conducted by an independent laboratory.
Under 410 IAC 38 § 410-38-5-2, before a certificate of decontamination can be issued for a property formerly used in illegal drug activity, a qualified inspector must test the property for a specific list of controlled-substance chemicals—including methamphetamine, amphetamine, LSD, MDMA, PCP, and others—using approved sampling and laboratory methods. Each chemical must be measured at or below 0.5 micrograms per 100 square centimeters to meet the standard decontamination threshold. An alternate threshold may be accepted by the commissioner if it is at least as protective of human health given the property's planned reuse. All sample analysis must be performed by an independent laboratory.

Property owners managing a formerly contaminated site under 410 IAC 38 § 410-38-5-2 generally work with a qualified inspector who reviews law enforcement reports and prior assessments to determine which Table 1 chemicals were present, then conducts sampling using Method 8270C or an equivalent approved method. Compliant operators ensure that all sample analysis is sent to an independent laboratory and that results confirm chemical levels at or below the 0.5 μg/100 cm² decontamination threshold before pursuing a certificate of decontamination. If the property's planned reuse warrants an alternate decontamination level, operators typically document that the alternate level is at least as protective of human health and seek acceptance from the commissioner as outlined in the provision.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Under 410 IAC 38 § 410-38-5-2, tenants have an interest in knowing that a property formerly associated with illegal drug manufacturing or use must meet specific chemical decontamination standards—verified by a qualified inspector and an independent laboratory—before a certificate of decontamination can be issued. If a tenant has concerns about whether a rental property has been properly decontaminated, they may request documentation of the certificate of decontamination or inquire about the inspection results with the relevant Indiana state authority. Tenant-rights organizations and local health departments can be resources for understanding what documentation a tenant may be entitled to review in connection with this provision.
