This Regulation Affects... 
The standards established in this regulation apply 
to most pre-1978 housing and child-occupied 
facilities (pre-1978 non-residential properties 
where children under the age of six spend a 
significant amount of time such as daycare 
centers and kindergartens). 
Anyone who must comply with other Title X 
regulations, whether issued by EPA, HUD, or by a 
State under an authorized program, may be 
affected by this regulation. The following list 
identifies some of the groups potentially affected 
by these standards: 
- Residential and child-occupied property owners, 
and owners receiving federal housing assistance. 
- Lead paint professionals. 
- Training providers. 
- Federal agencies. 
- Parents. 
What Happens If a Lead Hazard Is Identified? 
Property are required to notify occupants if they 
are aware of lead, whether or not it is identified as 
a hazard. However, this regulation does not 
require anyone to identify lead hazards, or that 
any specific action be taken if a lead hazard is 
identified. Please refer to the Protect Your Family 
brochure available through the National Lead 
Information Center for further information on 
disclosure of lead hazards to residents. 
Owners and other decision-makers should 
actively seek to reduce or prevent children’s 
exposure to lead in paint, dust, or soil that equals 
or exceeds these hazard levels. The Protect Your 
Family brochure provides some of these options. 
State, local, or tribal governments may have 
different standards or requirements. EPA 
recommends you contact them before beginning 
any work with lead paint.
