Summary
Rancho Cucamonga follows federal EPA RRP rules and California H and S 17920.10 treating deteriorated lead paint as a substandard housing condition. Pre-1978 homes are presumed to contain lead paint.
17920.10. (a) Any building or portion thereof including any dwelling unit, guestroom, or suite of rooms, or portion thereof, or the premises on which it is located, is deemed to be in violation of this part as to any portion that contains lead hazards. For purposes of this part, "lead hazards" means deteriorated lead-based paint, lead-contaminated dust, lead-contaminated soil, or disturbing lead-based paint without containment, if one or more of these hazards are present in one or more locations in amounts that are equal to or exceed the amounts of lead established for these terms in Chapter 8 (commencing with Section 35001) of Division 1 of Title 17 of the California Code of Regulations or by this section and that are likely to endanger the health of the public or the occupants thereof as a result of their proximity to the public or the occupants thereof.
(c) In the absence of new regulations adopted by the State Department of Health Services in accordance with the rulemaking provisions of the Administrative Procedure Act defining the term "disturbing lead-based paint without containment" or modifying the term "deteriorated lead-based paint," for purposes of this part "disturbing lead-based paint without containment" and "deteriorated lead-based paint" shall be considered lead hazards as described in subdivision (a) only if the aggregate affected area is equal to or in excess of one of the following:
(1) Two square feet in any one interior room or space.
(2) Twenty square feet on exterior surfaces.
(3) Ten percent of the surface area on the interior or exterior type of component with a small surface area. Examples include window sills, baseboards, and trim.
(d) Notwithstanding subdivision (c), "disturbing lead-based paint without containment" and "deteriorated lead-based paint" shall be considered lead hazards, for purposes of this part, if it is determined that an area smaller than those specified in subdivision (c) is associated with a person with a blood lead level equal to or greater than 10 micrograms per deciliter.
Full Breakdown
The federal Renovation, Repair, and Painting (RRP) Rule (40 CFR Part 745) requires EPA-certified firms and certified renovators to perform work that disturbs painted surfaces in pre-1978 housing and child-occupied facilities. California Health and Safety Code 17920.10 defines deteriorated lead-based paint in housing as a substandard building condition subject to enforcement under the Health and Safety Code and local code enforcement. Landlords must deliver the federal Protect Your Family from Lead pamphlet and a lead disclosure form to tenants in pre-1978 units, and sellers have similar disclosure obligations under 42 USC 4852d. Rancho Cucamonga Building and Safety handles abatement orders when deteriorated lead paint is reported. California Department of Public Health Childhood Lead Poisoning Prevention Branch investigates elevated blood-lead cases and can order remediation. Certified abatement contractors are required to perform actual lead hazard control. Use of prohibited lead-based paint and unsafe work practices can trigger both federal EPA penalties and local code enforcement.
