Title X Amendments Act of 2013

Title X Amendments Act of 2013 - Amends the Residential Lead-Based Paint Hazard Reduction Act of 1992 to revise the purpose for grants for lead-based paint hazard reduction in target housing.

Requires such grants to be made instead for reduction of lead-based paint hazards and correction of other housing-related hazards.

Authorizes the Secretary of Housing and Urban Development (HUD) to establish a process by which, in order to verify a family's income level, a grantee may first obtain and use income and program participation information from an entity administering: (1) the HOME Investment Partnerships program under the Cranston-Gonzalez National Affordable Housing Act; (2) the special supplemental nutrition program for women, infants, and children (WIC) established under the Child Nutrition Act of 1966; (3) reduced price or free lunches under the Richard B. Russell National School Lunch Act; (4) the weatherization assistance program for low-income persons established under the Energy Conservation and Production Act; (5) the temporary assistance for needy families (TANF) program under part A of title IV of the Social Security Act (SSA); (6) the supplemental security income (SSI) program under SSA title XVI; or (7) any other program consistent with the family income requirements of the Residential Lead-Based Paint Hazard Reduction Act of 1992.

Makes eligible to apply for such a grant, in addition to certain state or local governments, for specified activities relating to lead-based paint hazards: (1) an Indian tribe, and (2) private nonprofit organization partnering with the state or unit of general local government in which the activities will be carried out.

Makes a private nonprofit organization not partnering with a state or local government eligible all the same to apply for a grant to reduce housing-related health hazards, including any condition of residential real property that poses a risk of biological, physical, radiological, or chemical exposure that can adversely affect human health.

Revises grantee selection criteria for a grant to carry out activities relating to lead-based paint hazards, and prescribes criteria for activities relating to housing-related hazards.

Prescribes an allocation of funds for grants to assess and correct housing-related health hazards and evaluate the effectiveness of such assessments and corrections.

Reauthorizes the Act for FY2014-FY2018.
