Carrollwood is an unincorporated community, so Hillsborough County, not the City of Tampa, keeps most of its permit, code, and flood records, even though its addresses say Tampa. It also has records of its own to check, from a recreation district tax and deed restrictions in Original Carrollwood to homeowners associations in Carrollwood Village and creek gauges that, by our count, set records during Hurricane Milton. The notes below come from Census, county, state, and federal sources, plus the district's audited report and association websites where named, with rules and figures as of October 2026.
Unincorporated, even with a Tampa address
The Census Bureau counts Carrollwood as a census-designated place, its term for an unincorporated community with no legally defined boundary or government of its own. It had 34,352 residents in the 2020 Census. Addresses here read Tampa, with ZIP codes such as 33618 and 33624, but Census rules say no location can be in both a census-designated place and a city. By our count from Census and city map data, the City of Tampa line runs along part of Carrollwood's southeastern edge, about 600 feet east of Lake Carroll at its closest. Northdale, Lake Magdalene, Egypt Lake-Leto, Town 'n' Country, and Citrus Park are separate Census places, so their figures are not Carrollwood's. In Carrollwood, the county's HillsGovHub portal handles permits, and county code cases go before its Code Enforcement Board or a special magistrate. For a house near the city line, check the city's Address Look-up map first.
Homes from the 1970s and 1980s, and older permit files
Carrollwood's housing is older than the county's. Census Bureau estimates for 2020 to 2024 put its median year built at 1984, against 1991 for Hillsborough County. Of its 15,031 housing units, 41.6 percent went up in the 1980s. By our count, 91.6 percent were built before 2000, and about a quarter are in buildings with two or more units. As of October 2026, county building permits from 1976 through 2004 are not online; you request them with details such as the folio number. The county also says elevation certificates are not typically available for homes built before 2000. If an old permit was never closed, s. 553.79, Florida Statutes, lets the current owner close it, even if someone else applied for it. Under the same law, the county may close a permit 6 years after it was issued if it finds no apparent safety hazard, and it may not fine an arm's-length buyer solely because a prior owner's permit stayed open.
Original Carrollwood: deed restrictions and a district tax
Original Carrollwood, which Matt Jetton started beside Lake Carroll in 1959, is in the Carrollwood Recreation District, an independent special district approved by referendum in 1972 and now governed by chapter 99-418, Laws of Florida. Under that act, each improved residential parcel pays an equal recreation district tax, which appears on the property tax bill and is a lien until paid. The district's audited report shows $800 a unit for 926 units on the 2024 tax roll, under a $1,200 yearly cap that voters set in 2022. The Carrollwood Civic Association's website says it holds the developer's rights under the recorded deed restrictions and owns Lake Carroll. It says plans for additions and docks need its approval before work begins, and the covenants call for masonry construction. Ask the closing agent or a Florida real estate attorney about any past work done without that approval.
Carrollwood Village, other HOAs, and condos
Carrollwood Village, begun around 1970 northwest of the original subdivision, is split into three residential phases, each governed by a separate homeowners association, according to its association website. Phase III's 2024 community standards say a master declaration binds every owner. Under those standards, changing a roof's style or color, repainting beyond touch-ups, or changing a driveway needs approval from its architectural review committee. The county's neighborhood registry, whose entries here were last revised between 2015 and 2018, maps 29 homeowners associations and 10 condominium associations in Carrollwood, by our count. Where association membership is mandatory, s. 720.401, Florida Statutes, requires the seller to give the buyer a disclosure summary before the contract is signed. If it comes late, the buyer may cancel within 3 days of receiving it or before closing, whichever is first. A condo buyer is entitled, at the seller's expense, to the documents in s. 718.503, including the association's most recent structural integrity reserve study or a statement that it has not completed one.
Lakes, creeks, and what Milton did
Lake Carroll, White Trout Lake, Lake Ellen, Boat Lake, and Lake Lipsey all sit inside Carrollwood's Census boundary, and Sweetwater Creek and Brushy Creek run through it. By our count, about 13 percent of its land is in a FEMA special flood hazard area, mostly zone AE, and FEMA maps a regulatory floodway along parts of both creeks. The effective map puts Lake Carroll in zone AE with a base flood elevation of 38.6 feet (NAVD 88). During Hurricane Milton, a U.S. Geological Survey gauge at Roy Haynes Park recorded 13.43 inches of rain on Oct. 9, 2024. By our count, that was about twice its next-wettest day since 1999. On Oct. 10, Sweetwater Creek's gauge set a peak-flow record for data back to 1952, and Brushy Creek's set a record daily average level for data back to 1996, also by our count. Florida's flood disclosure under s. 689.302 treats sustained standing water from rainfall as flooding, not just water from a lake or creek.
The 50 percent rule, elevation records, and insurance
In a FEMA special flood hazard area, the county's 50 percent rule applies: if repairs or improvements cost 50 percent or more of the building's market value, not counting land, the whole house must meet current floodplain rules. The county's construction code and guidance still count work over a 12-month period. But since June 26, 2025, s. 163.31795, Florida Statutes, has barred local governments in the flood insurance program from adopting or enforcing such a period, so ask county floodplain staff how they will count your work. The county also maps its own floodplains from watershed studies and applies development rules there, though federal insurance requirements follow only FEMA's map. Elevation certificates filed after February 2021 are in HillsGovHub, those from 2005 to 2021 are in the county's online PGM Store, and older ones may be available on request. The county says FEMA moved it to Class 4 in the Community Rating System on Oct. 1, 2026, and that Class 4 brings a 30 percent discount on National Flood Insurance Program premiums for residents of unincorporated Hillsborough County.
Sinkhole reports in two public lists
The Florida Geological Survey's database of reported subsidence incidents lists 618 reports in Hillsborough County as of October 2026, more than any other county. By our count, 25 of them map inside Carrollwood's Census boundary, dated from 1975 to 2015, and none is marked as a verified sinkhole. The survey says most reports have not been field-checked. The Property Appraiser keeps a separate subsidence map of activity reported to its office. By our count, it flags 85 Carrollwood parcels, 69 shown as remediated and 16 as not remediated. It treats a parcel as remediated when a remediation permit was completed or the owner reported the repair. It also says a parcel with no flag is not proof that there is no sinkhole. If you made a sinkhole claim that your insurer paid, s. 627.7073(2)(c), Florida Statutes, requires you to tell the buyer before closing that it was paid and whether all of the money went to repairs.
