Polk City is a small municipality of 3,082 people (Census Bureau estimate, July 1, 2025; 2,713 in the 2020 Census) on 4.5 square miles of land in north Polk County. It is on State Road 33 north of Lakeland, about two miles from Interstate 4 by State Road 559, and City Hall is at 123 Broadway Boulevard SE.
The town is in the Green Swamp, the region of wetlands and uplands where four Central Florida rivers begin. The state’s Green Swamp Area of Critical State Concern surrounds it and takes in part of it. That designation is the main thing to understand before building, adding on or buying land here.
Homes and neighborhoods
Polk City has 1,110 housing units (ACS 2020-2024): 82 percent are single-family detached homes and 10 percent are mobile homes. The census median build year is 2007, and about 47 percent of homes were built in 2010 or later. This is a small place, so the survey’s margins of error are wide.
County plat records (read in October 2026) show how the town was laid out:
- The older plats are Railroad Heights (1924), Oakridge Heights (1926) and the Polk City plat (1926).
- Orangewood Village was platted in seven units from 1977 to 1989, Citrus Harbour in 1978 and Sandy Pointe in 1990.
- Mount Olive Shores North was platted in additions from 1997 to 2008, with 270 lots in the fourth.
- Fountain Park was platted in three phases (2007, 2018 and 2019), about 360 lots in all.
- Landings at Mount Olive is the newest, with plats recorded in 2025 and 2026 and 258 lots so far.

The Green Swamp Area of Critical State Concern
FloridaCommerce, the state’s land planning agency, describes the area as about 322,690 acres in northern Polk and southern Lake counties, designated by the Legislature in 1979. The Floridan Aquifer reaches its highest elevation here, and the swamp’s wetlands form the headwaters of the Withlacoochee, Oklawaha, Peace and Hillsborough rivers.
Where the line runs. The state rule that draws the boundary (Rule 28-26.002, Florida Administrative Code) encloses the land around Polk City but leaves out the south half of Sections 28 and 29 and all of Sections 32 and 33 of Township 26 South, Range 25 East. County parcel records put the town’s older plats in those sections. Newer parts of the city, such as Fountain Park and Landings at Mount Olive, are in other sections, and the county’s map shows them and the land on every side of town inside the area. Check a parcel on the Green Swamp layer of the county’s map viewer and confirm with City Hall.
What it means for building. Inside the area:
- FloridaCommerce reviews all local development projects and may appeal a local development order to the Florida Land and Water Adjudicatory Commission. It also has to approve changes to the local comprehensive plan and land development regulations.
- Local rules must follow the state’s principles for guiding development: platting and site alteration only where they will not change the natural flow of surface water or reduce aquifer recharge, stormwater released to wetlands in a way that approximates natural flow, and structures placed in line with floodplain management.
- In the county land around the town (the Polk City/Urban Growth Special Protection Area of Polk County’s Land Development Code), residential development sets aside at least 30 percent of its land as open space, a detached single-family lot may not be more than 50 percent impervious surface, and development connects to central water and sewer where they are available.
- Septic systems there need a lot of at least 40,000 square feet, a 75-foot setback from wetlands and an inspection at least every five years.
- Lots of record are exempt from the county’s Green Swamp density limits, but the other requirements still apply.
Inside the city limits, Polk City’s own Unified Land Development Code and comprehensive plan apply. Before you buy a vacant lot or plan a pool, an addition or a larger driveway, ask the city or the county which impervious surface limit and wetland setbacks apply, and allow time for state review of anything that needs a development order.
Property taxes in Polk City
Florida taxes a home on its assessed value less exemptions, times the millage of its taxing district. The 2025 rates:
| Taxing authority | 2025 millage |
|---|---|
| Polk County general fund | 6.6348 |
| Polk County School Board | 5.2900 |
| Southwest Florida Water Management District | 0.1831 |
| City of Polk City | 5.2500 |
| Total (mills) | 17.3579 |
The Property Appraiser’s 2026 notices proposed a total of 18.0759. Homes outside the city limits pay the county’s unincorporated rate, 12.9291 mills in 2025.
On a home assessed at $300,000 with no homestead exemption, 17.3579 mills is about $5,207 for 2025. With homestead it is about $4,463: the exemption takes $25,000 off for all taxes and a second amount off the non-school taxes on value above $50,000 ($25,722 in 2025; it rises with inflation each January 1).
A homesteaded home’s assessed value can rise no more than 3 percent a year or the change in the Consumer Price Index, whichever is lower (2.7 percent for 2026). Other residential property is capped at 10 percent a year, except for school taxes. A sale resets the assessment to market value the next January 1, so a buyer’s bill can be much higher than the seller’s. TRIM notices arrive in August (mailed from August 18 in 2025). Taxes are payable from November 1, with a 4 percent discount in November falling to 1 percent in February, and are delinquent April 1.
CDD and HOA fees
Polk County’s records list no Community Development District parcels in Polk City as of October 2026. The single-family parcels we checked carry Polk County’s fire services assessment, $385.00 on the 2026 roll.
Some subdivisions have a homeowners association. Florida’s estoppel certificate (section 720.30851, Florida Statutes) is how a buyer gets the association’s own figures, and we can request it and the HOA documents for a home you are considering.
Short-term rental rules
A home’s zoning and its association’s documents both have to allow short-term rental. The city code published on Municode has no short-term rental section, and the city’s Unified Land Development Code is kept separately, so check with the city’s planning office before buying for that purpose. Outside the city limits, Polk County’s Section 303 approves the use by subdivision or phase, not house by house.
State law bars local rules that prohibit vacation rentals unless the rule was adopted on or before June 1, 2011. A short-term rental needs a vacation rental license from Florida’s DBPR, and stays of six months or less owe Polk County’s 5 percent tourist development tax, Florida’s 6 percent sales tax and the county’s sales surtax.
Schools
Polk County Public Schools serves Polk City. Attendance zones go by address: the district’s School Zones page has an address lookup and a GeoZone map for a planned move. The district lists charter schools on its Charter Schools page.
Utilities
The city code sets up city water, sewer and stormwater utilities and has the city arrange solid waste collection. The city’s FAQ says electricity comes from Lakeland Electric or Tampa Electric, depending on the address. Homes outside the city limits may not have city water or sewer, so confirm for the address.
Getting around
From City Hall, the OpenStreetMap route to Lakeland follows State Road 33: about 15 miles and 23 minutes without traffic. I-4 is about two miles away by State Road 559. Orlando International Airport is about 43 miles and 57 minutes by I-4 and the State Road 417 toll road, and Tampa International Airport about 52 miles and 65 minutes. I-4 traffic is heavy at peak hours, so real times vary.
Flood zones and insurance
FloridaCommerce describes the Green Swamp’s wetlands as holding seasonal floodwater, and in the county’s part of the area a flood hazard statement goes on plats and permits. Search an address on FEMA’s Flood Map Service Center; Polk County Floodplain Management offers free flood assistance by phone. Citizens Property Insurance Corporation requires a four-point inspection (electrical, plumbing, heating and cooling, roof) on homes more than 20 years old and explains wind mitigation inspections on its site.
Parks and things to do
- The General James A. Van Fleet State Trail, a Florida state park, is a paved rail trail of about 29 miles that runs north from its Polk City trailhead through the Green Swamp.
- The Green Swamp Wilderness Preserve, managed by the Southwest Florida Water Management District, has five units; its East Tract covers 51,149 acres.
- Fantasy of Flight, an aircraft museum at 1400 Broadway Boulevard SE near I-4, operates seasonally; check its calendar.
