For a Target Housing dwelling with 25 units, how many units must be tested?

In the context of lead-based paint regulations, particularly for Target Housing, there are specific guidelines related to the sampling and testing of residential units for lead hazards. When a dwelling consists of multiple units, the regulations stipulate that a certain percentage of the total units should be tested to ensure that the presence of lead is properly assessed.

For a property with 25 units, a standard practice is to test 4 units, which aligns with the requirement of testing a minimum proportion of the total number of units. This approach balances the need for a comprehensive assessment of lead hazards with practical considerations regarding the resources and time required for testing.

The rationale for testing 4 units specifically comes from established sampling strategies that provide sufficient data to determine the likelihood of lead contamination across the entire property without overburdening the evaluation process. It is essential to follow these guidelines to ensure compliance with EPA regulations and to adequately protect residents from potential lead exposure.
