Cal. Civ. Code § 6-830
Md. Code Ann., Environment Art. Title 6, Subtitle 8 — Lead Poisoning Prevention Program
Operative Text
(a) If, between February 24, 1996 and February 23, 2001, inclusive, the concentration of lead in a whole venous blood sample of a person at risk tested within 30 days after the person at risk begins residence or to regularly spend at least 24 hours per week in an affected property that is certified as being in compliance with the provisions of § 6–815 of this subtitle is greater than or equal to 25 �g/dl, or, between February 24, 2001 and February 23, 2006, inclusive, greater than or equal to 20 �g/dl, or, on or after February 24, 2006, greater than or equal to 15 �g/dl, it shall be presumed that the ingestion of lead occurred before a person at risk began residing or regularly spending at least 24 hours per week in the affected property. (b) On or after July 1, 2006, the EBL concentration of lead in a blood sample shall be determined in accordance with § 6–801(f) of this subtitle.
Under Md. Code Ann., Env. §§ 6-801 to 6-852 § 6-830, Maryland law establishes a legal presumption about the source of lead exposure when a person at risk is tested shortly after moving into or regularly spending time in a certified rental property. If that blood-lead test meets or exceeds the applicable threshold—which has been lowered in phases from 25 µg/dL before 2001, to 20 µg/dL through 2006, and to 15 µg/dL thereafter—the law presumes the lead ingestion happened before the person arrived at that property. This presumption effectively shifts the evidentiary burden regarding where the lead exposure originated, and blood-lead determinations made on or after July 1, 2006 must follow the definition set out in § 6-801(f).
Plain English — not legal advice.
Property owners and managers operating under Maryland's lead-paint risk-reduction program should be aware that § 6-830 creates a presumption that works in favor of a certified property when a person at risk tests above the threshold blood-lead level within 30 days of taking up residence or regular occupancy. Maintaining current certification under § 6-815 and documenting the timing of that certification relative to a new occupant's arrival are practices consistent with being able to invoke this presumption. Operators generally keep records of inspection dates, certification status, and tenant move-in dates so that the timeline required by Md. Code Ann., Env. §§ 6-801 to 6-852 § 6-830 can be clearly established if a blood-lead issue arises.

Md. Code Ann., Env. §§ 6-801 to 6-852 § 6-830 contains a presumption that can affect how a lead-exposure claim is evaluated: if a person at risk has a blood-lead level at or above the applicable threshold when tested within 30 days of moving in, the law presumes the exposure happened before that move-in—potentially limiting the property's liability for that exposure. Tenants and families who believe lead exposure occurred at a rental property may want to understand how this presumption interacts with their situation, including whether the property held valid § 6-815 certification at the time of occupancy. Tenant-rights organizations and local health departments can help explain how blood-lead testing timelines and certification records factor into any complaint or legal proceeding under this provision.
