The "Affordable Housing and Supportive Services Act for Persons with Developmental Disabilities" seeks to improve access to affordable housing and support services for individuals with developmental disabilities in Florida. It introduces a new section in the Florida Statutes, Section 420.629, which includes legislative findings, definitions, and incentives to encourage the development of affordable housing. Key provisions of the bill include exemptions from ad valorem taxation for eligible properties, tax credits for businesses that employ qualified individuals, and the creation of a Tenant-Based Rental Assistance Program to provide rent subsidies. Additionally, it mandates the waiver of certain impact fees by local governments for eligible residential units and requires the Department of Revenue to issue tax refunds for building materials used in these developments.

The bill also enhances support for businesses and individuals with developmental disabilities by establishing a framework for tax credits capped at $500,000 per year, allowing tax refunds on sales tax for electricity, and providing grants for workplace modifications and training. It prioritizes funding for affordable housing developments through the Florida Housing Finance Corporation and establishes a State Loan Insurance Program for qualified developers. The Tenant-Based Rental Assistance Program will offer rental subsidies and wraparound services, including housing transition services and vocational training. Compliance measures include annual audits of participating entities, penalties for noncompliance, and an appropriation of $1 million for the Department of Commerce for the 2025-2026 fiscal year, with the bill set to take effect on July 1, 2025.
