Where Crystal Island is

Pinellas County parcel data places Crystal Island homes on Crystal Drive, Johns Pass Avenue, Lillian Drive and Flamingo Drive, all with Madeira Beach addresses. Florida Neighborhood Realty’s Madeira Beach overview calls it an island enclave with waterfront homes, direct water access and boat docks.

What county records show

The county records Crystal Island as three plats, Crystal Island and its first and second additions, with about 267 parcels: 238 coded as single-family homes and 28 vacant, including a park area on Lillian Drive. Neighborhoods.com says the community dates to 1958, with homes built from 1958 to 2003 and roughly 1,300 to 4,500 square feet.

Water and boating

For a waterfront lot, confirm depth at the dock and along the route to open water, bridge clearance, dock and lift permits, and seawall condition. Our seawall and dock inspection guide lists what to look for.

Flood zones, elevation and the 2024 storms

Hurricane Helene pushed a major surge into Pinellas County in September 2024; the National Hurricane Center Helene report lists water levels of 7.26 feet above mean higher high water at Madeira Beach. Hurricane Milton followed two weeks later. For any Crystal Island address, look up the zone on the FEMA Flood Map Service Center, check for an elevation certificate on the Pinellas County elevation certificate map, and ask whether the city made a substantial damage determination. Madeira Beach also runs a Forerunner flood data portal where owners can look up flood zone, base flood elevation, elevation certificates and substantial damage history by address.

Rental rules

According to the Pinellas Realtor Organization summary of local rental rules, Madeira Beach prohibits rentals of less than six months in R-1 districts and less than three months in R-2 districts. The city business license FAQs say every rental needs a city Business Tax Receipt. Check the zoning of the specific Crystal Island lot with the city before you count on rental income, and see our short-term rental rules by city.
