IL HB4059

Amends the Rental Property Utility Service Act to require utility companies to provide prospective tenants and landlords with utility billing information for the preceding 2 years upon written request, identified only by unit address with no tenant or owner identifiers.

Requires landlords to provide prospective tenants with a written statement detailing all building areas served by the unit's meter and potential future utility uses before offering a lease or accepting a deposit.

Mandates landlords provide prospective tenants with copies of utility bills for the previous 12 months unless waived in writing, and prohibit landlords from suggesting or requiring tenants to collect utility payments from neighboring tenants.

Requires landlords to set forth in writing any proposed rent reduction offered to compensate tenants for utility payments outside their unit.

Prohibits landlords from changing utility payment arrangements from landlord-paid to tenant-paid during a lease term and requires a minimum of 30 days' notice before such changes, with written lease amendment required if both parties agree to change the arrangement.
