Sun Communities Inc. Discloses Data Breach Affecting Tenant Data

Sun Communities Inc., a company involved in residential property management and real estate, filed a data breach notification with Indiana regulators on February 6, 2026. This filing stemmed from a data security incident that occurred on or about December 25, 2025. The specific method of the breach was not detailed in the public records available.

According to the official filing, the exposed categories of personal information include Full Name, Social Security Number, Date of Birth, Residential Address History, Driver License Number, Banking Account and Routing Numbers, Lease Agreement and Payment History, and Background Check and Screening Files. This range of data, typically stored by property management firms, was reportedly compromised during the incident.

The exposure of such extensive personal and financial data carries risks for affected individuals. Compromised information could potentially be used for various forms of identity theft, unauthorized account access, or other fraudulent activities. Individuals whose lease agreements and background checks were involved may face heightened concerns due to the detail of the information exposed.

Individuals who received a data breach notification from Sun Communities Inc. should consider monitoring their financial accounts and credit reports for any suspicious activity. Placing a fraud alert or security freeze on credit files with the major credit bureaus is a widely recommended precaution. Additionally, be vigilant against phishing attempts or unsolicited communications requesting personal details. Regularly review statements from banks and other financial institutions for unauthorized transactions.
