Note: Dunedin is largely built-out, with most new residential activity consisting of individual custom infill single-family homes or small spec builds by local builders (e.g., Covenant Homes, DiGiovanni Homes) rather than large master-planned communities. The projects above represent the primary verifiable named new construction/mixed-use developments announced or underway. Limited public information is available on additional smaller or pipeline projects.
