Kolter Group Plans 510-Unit Alton Seminole Development In Sanford

• Kolter Group proposes 510-unit multifamily project in Sanford, Florida
• Two-phase development across 22 acres with a workforce housing component
• Project leveraging Live Local Act incentives to boost density and approvals

What the project means for suburban development in Central Florida

Kolter Group is advancing plans for Alton Seminole, a large-scale multifamily development in Sanford that reflects continued expansion into suburban growth markets. The project will span 22 acres and deliver 510 residential units, replacing underutilized land owned by Central Florida Regional Hospital. This type of suburban infill highlights how developers are targeting larger parcels outside urban cores to meet housing demand. Sanford’s proximity to Orlando and regional employment hubs makes it an attractive location for new residential supply.

What the phased construction plan means for delivery

The development will be built in two phases, allowing Kolter to stage construction and lease-up over time. Phase one includes 270 units across a mix of three- and four-story buildings, while phase two will add another 240 units with a similar configuration. This phased approach helps manage construction risk and align delivery with market absorption. Average unit sizes just under 1,000 square feet suggest the project is targeting workforce renters rather than luxury tenants.

What the Live Local Act means for development strategy

Kolter is utilizing Florida’s Live Local Act to unlock incentives tied to workforce housing. To qualify, at least 40 percent of the units will be designated for households earning up to 120 percent of the area median income. In exchange, developers benefit from increased density and fewer regulatory hurdles. This framework is becoming a key tool for developers across Florida, enabling larger projects while addressing housing shortages.

What amenities and design say about renter demand

The project will include a full amenity package with a clubhouse, pool, dog park, and recreational trails, aligning with suburban renter preferences. These features are designed to attract long-term tenants seeking a balance between affordability and lifestyle, particularly in markets where homeownership has become less attainable. The garden-style format also reflects a cost-efficient construction approach compared to mid- or high-rise buildings.

What this means for developers and investors

Alton Seminole highlights the continued strength of suburban multifamily development in Florida. For developers, leveraging legislation like the Live Local Act can unlock scale and improve project feasibility. For investors, workforce housing projects offer stable demand and lower volatility compared to luxury assets. As population growth continues across Central Florida, projects like this are well-positioned to capture long-term rental demand.
