Certain families in Lawrence may qualify for financial assistance in weatherizing their homes, the city said Monday in a news release.

Weather preparation includes tasks such as installing storm windows, weather-stripping doors and insulating attics. The money is available for qualifying families through a Community Development Block Grant from the city’s Planning and Development Services Department.

Mobile homes are not eligible for assistance, the release said.

Homes applying for assistance must not have received similar financial aid from the city since Jan. 1, 1993, the release said. Each home must be owner-occupied and hold no more than two dwelling units.

To qualify for financial assistance each family’s gross annual income may not exceed the following family-size/maximum-income guidelines:

• 1: $39,950
• 2: $45,650
• 3: $51,350
• 4: $57,050
• 5: $61,650
• 6: $66,200
• 7: $70,750
• 8+: $75,350

Grants for energy-saving improvements do not need to be repaid.

Money will be allocated on a first-come, first-served basis, the release said. Grant applications are available at the Planning and Development Services offices at 1 Riverfront Plaza, Level 1, Suite 110, or online at www.lawrenceks.org/pds/housing_programs.

The application deadline is Aug. 31 by 5 p.m.
