If you own a California residential or public building constructed before January 1, 1978, California lead abatement regulations presume the paint contains lead and require you to use state-certified people to evaluate and remove it, notify the Department of Public Health five days before work begins, and pass an independent clearance test before the space is reoccupied. Violate the certification requirement and the civil penalty starts at $5,000 per day, per violation.
When the Rules Apply to Your Property
California defines lead-based paint as any paint or surface coating with lead at or above one milligram per square centimeter or half of one percent by weight.1Legal Information Institute. California Code of Regulations Title 17 Section 35033 – Lead-Based Paint Any paint on a structure built before January 1, 1978, is treated as presumed lead-based paint unless testing proves otherwise. If your building is newer, these rules generally don’t reach you.
Under Health and Safety Code Section 17920.10, deteriorated lead-based paint, lead-contaminated dust, lead-contaminated soil, and disturbing lead-based paint without containment all qualify as lead hazards when present in amounts that meet or exceed regulatory thresholds. Those thresholds are lower than most owners expect:
- Interior deteriorated paint: two square feet in a single room
- Exterior deteriorated paint: twenty square feet
- Small components (window sills, baseboards, trim): ten percent of the surface area
A single peeling bedroom window frame can be enough to make a rental unit legally substandard when the paint is presumed to contain lead.
Who Has to Comply
The regulations primarily target pre-1978 residential dwellings and child-occupied facilities. Child-occupied facilities include daycare centers, preschools, and similar buildings regularly visited by children under six.3eCFR. 40 CFR Part 745 – Lead-Based Paint Poisoning Prevention in Certain Residential Structures These sites face heightened scrutiny because young children are the most vulnerable to lead poisoning.
Landlords and property management companies carry direct legal responsibility for identifying and addressing lead hazards in rental housing. Local code enforcement agencies can order abatement in any rental unit found to be substandard, and state Housing Law requires those orders when hazards are identified.2California Legislative Information. California Health and Safety Code 17920.10
Some properties sit outside the federal evaluation and hazard reduction rules: zero-bedroom dwelling units, housing designated exclusively for the elderly or persons with disabilities where no child under six resides, and properties already confirmed lead-free by a certified inspection. Federally assisted housing has an extra layer: when a child under six living there is identified with an elevated blood lead level, the owner must complete an environmental investigation within 15 calendar days and finish hazard reduction within 30 days of the investigation report.4eCFR. 24 CFR Part 35 – Lead-Based Paint Poisoning Prevention in Certain Residential Structures
Abatement Is Not the Same as Renovation
This distinction trips up owners constantly. Lead abatement is a specialized project designed to permanently address lead-based paint hazards. A renovation, repair, or painting (RRP) project disturbs lead-based paint as a side effect of other work, such as remodeling a kitchen, replacing windows, or repainting a room.5U.S. Environmental Protection Agency. Lead Abatement Versus Lead RRP
Both require certified workers and firms, but the rules differ:
- Abatement projects require occupants to leave the home, child care facility, or preschool. RRP projects don’t force occupants out, though they must stay out of the active work area.
- Abatement may be ordered by a government agency (for example, after a child is diagnosed with lead poisoning) or requested voluntarily. RRP projects are always initiated by the property owner.
- Abatement requires post-work clearance by an independent certified inspector. RRP projects require cleaning verification under a different protocol.
Under the federal RRP rule, minor repairs disturbing six square feet or less of painted surface per room indoors, or twenty square feet or less outdoors, are exempt, as long as no prohibited work practices are used and the work doesn’t involve window replacement or demolition.3eCFR. 40 CFR Part 745 – Lead-Based Paint Poisoning Prevention in Certain Residential Structures Replacing a single window would not qualify, even if the paint area disturbed is small.
A Major Change Coming July 1, 2027
After July 1, 2027, any firm performing renovation, repair, or painting work for compensation that disturbs lead-based paint or presumed lead-based paint in a residential or public building must hold a CDPH certificate, and at least one certified person must be on-site and employed by the firm during the work. That dramatically widens the pool of certified labor you’ll need: general contractors doing routine renovation in pre-1978 buildings will fall under the rule if their work disturbs any painted surfaces. CDPH must run an education and outreach program on or before July 1, 2026, to prepare affected firms.6California Legislative Information. California Health and Safety Code 105254 Hiring an uncertified firm for RRP work after that date exposes you to a $10,000-per-day minimum penalty alongside the contractor.
Hiring Certified People
The California Department of Public Health requires certification for anyone performing lead hazard evaluations, abatement plan preparation, abatement work, or clearance inspections in residential and public buildings.7California Department of Public Health. Childhood Lead Poisoning Prevention Branch – Types of Certification Firms doing abatement must also hold CDPH certification and employ properly trained personnel.
Verify both the firm’s certification and each worker’s certification before any work starts. Hiring uncertified workers doesn’t just expose you to penalties; it likely voids any clearance results and forces you to start over. Also check that the person evaluating your property is not from the same firm you plan to hire for the abatement. The inspector who evaluates the property cannot also perform the abatement on the same structure.8Legal Information Institute. California Code of Regulations Title 17 Section 36000 – Requirements for Lead Hazard Evaluation for Public and Residential Buildings
What a Compliant Abatement Project Looks Like
A lead hazard evaluation must be performed by a certified lead inspector/assessor using the procedures in HUD’s Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, and must produce quantitative results. Inspectors using X-ray fluorescence (XRF) analyzers need a separate license and eight hours of specialized training beyond their base certification. A risk assessment goes further than a basic inspection, adding a written description of abatement options for each identified hazard, suggested prioritization, and recommendations for ongoing maintenance and monitoring.8Legal Information Institute. California Code of Regulations Title 17 Section 36000 – Requirements for Lead Hazard Evaluation for Public and Residential Buildings
Before abatement starts, the person doing the work must complete an Abatement of Lead Hazards Notification (CDPH Form 8551) and deliver a copy to CDPH at least five days before work begins. A copy must also be posted at all entrances to the work area and stay posted until abatement and clearance inspection are complete.9Legal Information Institute. California Code of Regulations Title 17 Section 36100 – Requirements for Abatement for Public and Residential Buildings10California Department of Public Health. Childhood Lead Poisoning Prevention Branch – Lead Hazard Reduction Activities Abatement Notification Requirements Frequently Asked Questions Abatement conducted in response to an identified case of lead poisoning (as defined in Health and Safety Code Section 105280(b)) is exempt from the five-day advance period, but notification is still required.
Keep records. Work plans, containment strategies, worker certifications, and clearance testing results all need to be maintained, along with a post-abatement report covering methods used and clearance results. Under California’s occupational safety regulations, training records and written compliance program records must be retained for at least three years. Regulators can request these during inspections or enforcement actions.
Clearance Testing
This is where corners get cut most often, and where regulators look hardest. A clearance inspection must be conducted by a certified lead inspector/assessor or certified lead project monitor who is independent of the firm that performed the abatement.8Legal Information Institute. California Code of Regulations Title 17 Section 36000 – Requirements for Lead Hazard Evaluation for Public and Residential Buildings
The EPA’s dust-lead clearance levels decide whether a property is safe for reoccupation:
- Floors: 5 micrograms per square foot
- Window sills: 40 micrograms per square foot
- Window troughs: 100 micrograms per square foot
Fail clearance and the space is still contaminated. Nobody moves back in until additional cleaning and retesting produce a passing result. Build time and budget for the possibility; a single failed test can delay a project by days or weeks.
Disclosure When You Sell or Lease
Before selling or leasing any pre-1978 housing, federal law requires you to disclose known information about lead-based paint hazards, provide all available records and reports on lead in the property, include a specific lead warning statement, and give buyers up to ten days to hire a certified inspector.12Environmental Protection Agency. Protect Your Family From Lead in Your Home You must also provide the EPA-approved pamphlet “Protect Your Family from Lead in Your Home” to prospective tenants or buyers.4eCFR. 24 CFR Part 35 – Lead-Based Paint Poisoning Prevention in Certain Residential Structures
The duty applies whether or not you’ve tested. If you know about hazards, disclose them. If you don’t know, say so. Claiming ignorance later won’t protect you if records show you had reason to know.
Enforcement and Penalties
Local health departments, code enforcement agencies, and CDPH inspect in response to tenant complaints, routine housing code enforcement, and reported cases of childhood lead poisoning. Active abatement projects are also inspected for compliance with safety protocols.
Under Health and Safety Code Section 105256, agencies can issue an order to abate or a cease-and-desist order for any activity creating a lead hazard. State Housing Law requires local agencies to order abatement of lead hazards identified as substandard conditions, typically with a 30-day compliance deadline.2California Legislative Information. California Health and Safety Code 17920.10 Refusing to obey an abatement order is an infraction with a fine up to $1,000 for the first offense, and a misdemeanor with a fine up to $5,000 or up to six months in county jail for repeat offenses.13California Legislative Information. California Health and Safety Code 105256 When inspectors find an imminent health risk, agencies can require tenant relocation at the owner’s expense.
The civil penalty structure under Health and Safety Code Section 105254 is steeper than many owners realize. Violating the certification requirement for abatement work carries a civil penalty of no less than $5,000 per violation per day. Starting July 1, 2027, violating the RRP certification requirement carries a minimum of $10,000 per violation per day. Each subsequent violation can reach $37,500 per violation per day. When setting penalties, the court or agency considers the seriousness of the misconduct, the number of violations, how long it persisted, whether it was willful, and the violator’s financial situation.6California Legislative Information. California Health and Safety Code 105254
Federal exposure stacks on top. The EPA enforces the RRP rule and can impose its own penalties. Landlords who skip required federal lead disclosures can be sued by tenants under consumer protection statutes, and those cases often settle for significant amounts. Repeated violations or willful concealment of known hazards can lead to a property being declared uninhabitable.
What This Costs
Professional lead paint inspections for a residential property generally run between $300 and $700, depending on the size of the home and the number of surfaces tested. A full risk assessment, with dust and soil sampling alongside paint testing, sits at the higher end of that range or above it.
Abatement varies widely. Professional lead paint removal typically ranges from roughly $6 to $17 per square foot, which pushes a full-house project into five figures quickly. Encapsulation and enclosure methods generally cost less than full removal, though they may not satisfy every regulatory requirement depending on the severity of the hazard. Get multiple bids from CDPH-certified firms and confirm each bid accounts for independent clearance testing, which contractors sometimes leave out of initial estimates.
