Local data
What is land in Union County worth?
These are open-market sale prices. A direct cash offer is usually lower, because a cash buyer closes in days and takes on the time and cost of reselling the lot.
| Vacant residential lots | 680 parcels classified vacant residential on the 2026 tax roll [1] |
|---|---|
| Most common lot size | One-acre homesite (40,000–46,000 sq ft): 22% of vacant lots; next, mini-estate (2-3 acres) at 15%. Median lot: 1.00 acre (43,560 sq ft). [1] |
| Typical assessed value | $16,900 median just (market) value for a vacant lot; the middle half fall between $11,000 and $25,000 [1] |
| Recent lot sale prices | Too few arm's-length vacant-lot sales in 2025 to report a reliable median for Union County [1] |
| Owners who live elsewhere | 5% of vacant lots have an owner mailing address outside Florida (most often GA, MI, NJ) [1] |
| Appraiser values; clerk records deeds | Bruce D. Dukes places a value on each parcel for tax purposes. He does not set the bill; taxing authorities set the rates. Florida law makes the circuit court clerk the county recorder and directs deeds to the Official Records. [2],[9] |
| November discounts, then a March gross | Collection starts November 1. November payers get four percent off, December three percent, January two percent, and February one percent. The gross amount is due by March 31. [5],[4] |
| A certificate is a lien, not the land | On or before June 1 the collector sells certificates. The amount stacks unpaid tax, paving, stormwater, and solid-waste assessments, a three percent penalty, a five percent commission, and advertising. Bids open at 18 percent and fall. [7],[6],[4] |
| Health department still permits septic | This was not among the 16 counties where DEP began septic permitting on January 2, 2025. DEP directs applicants to send Form DEP4015, a site plan, a floor plan, and the fee to the county health department. A qualified professional performs the site evaluation. [10],[11] |
| Santa Fe plan and the one-acre rule | June 2025 Santa Fe plan covers over one million acres, including parts of this county. The nitrate target is a monthly average of 0.35 mg/L. Without sewer, a new system needs a 65 percent nitrogen cut on an acre or less, or any size in a priority focus area. [12],[13] |
| Well construction is its own permit | The Suwannee River Water Management District must permit every new water well under rule 40B-3. Domestic use is exempt from a water-use permit. That exemption does not replace the construction permit. This county is on the district list. [14],[15] |
| Santa Fe flood study, then a restudy | The February 4, 2009 flood study examined Santa Fe overflow in detail. FEMA set November 2, 2018 for later map changes here. A Santa Fe watershed project with FEMA, started in February 2021, has draft map edits. [17],[18],[3] |
| 2022 built-parcel wastewater mix | A 2022 health-department map of built parcels shows 1,340 known septic parcels (34.4 percent) and 2,144 likely septic parcels (55.0 percent). Known sewer was 1 parcel. That map is not the vacant-lot count. [19] |
| Santa Fe River | The Santa Fe River separates Union County from Alachua County. FEMA studied its overflow in detail and describes adjacent soils as poorly drained and subject to prolonged flooding, making the south-county river edge a parcel-level flood issue. [22],[17] |
| Vacant lots that got a home on the tax roll in 2025 | 24 recorded with new-construction evidence. [1] |
| 2026 so far (Jan-Jun) | 9 recorded vacant-lot sales; median $53,000. [1] |
| FEMA high-risk flood-zone screen | About 11.4% of vacant lots in Union County have their center point in a FEMA high-risk flood zone (effective maps dated June 16, 2006 to November 2, 2018). This is map screening, not a determination; check FEMA's Map Service Center for your parcel. |
| Springs BMAP small-lot screen | About 54.1% of located vacant lots in Union County are 1 acre or less and have their center point in an adopted Florida springs BMAP. |

How selling land works in Union County
One-acre homesites can trigger the Santa Fe septic rule
A one-acre homesite can trigger the Santa Fe septic rule for a new tank. That size is the most common vacant residential lot here, about 22% of them, and the median lot is 1.00 acres. Middle just value on the roll is $16,900, not a sale price. DEP's June 2025 Santa Fe plan covers over one million acres and includes parts of this county, not every parcel. From July 1, 2023, a new conventional tank is barred where central sewer already serves a lot of one acre or less. If sewer is missing inside the plan, a new tank on an acre-or-smaller lot, or on any lot in a priority focus area, must be a DEP-approved enhanced system with a 65 percent nitrogen cut. The Ichetucknee focus area is only about 40 acres here. Existing tanks need not add nitrogen treatment at repair. See whether the parcel is inside that plan before assuming a conventional tank is allowed. [12],[13],[10],[11],[1]
Well permits, building permits, and river permits differ
A well permit, a county building permit, and a river permit are three different approvals. All water-well construction must be permitted by the Suwannee River Water Management District under rule 40B-3. Domestic use is exempt from a water-use permit, but the well still needs a construction permit. The residential application requires a survey and legal description, a health-department septic permit or letter, or a municipal sewer and water tap receipt. Unincorporated land also needs a flood-data letter from the building department. In a flood zone the form requires a base flood elevation and a flood elevation certificate before the permit. Wind calculations must cover at least 130 mph. Filing is online through Cloudpermit. The Santa Fe is a Works of the District river. A house, driveway, fill, or clearing in the floodway can need a separate permit. A written exemption letter costs $100. [14],[15],[16],[20],[21]
Unpaid tax becomes a lien well before a deed sale
Unpaid real estate tax becomes a lien, and only later can it support a tax-deed case. Lisa B. Johnson's office starts collection on November 1. Discounts are four percent in November, three percent in December, two percent in January, and one percent in February. On April 1 the balance is delinquent and a three percent penalty is added. On or before June 1 certificates sell in a reverse auction opening at 18 percent. The amount includes unpaid tax, paving, stormwater, and solid-waste assessments, the penalty, a five percent commission, and advertising. Certificates date from the sale's first day and expire after seven years. If interest earned is under five percent, a mandatory five percent charge is still due. The collector cites a 22-month redemption window. State law allows a tax-deed application two years after April 1 of the issue year, and the collector may charge $75. [4],[5],[6],[7],[8]
Flood risk follows the Santa Fe, not a countywide zone
Flood risk follows the Santa Fe River and the mapped floodway, not one zone for every acre. The February 4, 2009 study examined Santa Fe overflow in detail, plus an unnamed tributary meeting the river just upstream of State Road 121 and running about two miles. FEMA, the district, and the county agreed on that scope. The study calls this the smallest county in Florida, about 240 square miles, with over 80 percent in commercial forest. Riverside soils are described as nearly level, very poorly drained, and subject to prolonged flooding. It calls September 1964 the largest Santa Fe flood in that study. A July 20, 2018 FEMA notice set November 2, 2018 for newer flood-map information here and in incorporated areas. A district and FEMA project begun in February 2021 has draft maps that can move some land into or out of a flood zone. No source gives one zone letter to the whole county. [17],[18],[3]

Questions
Selling land in Union County: common questions
Can I sell my lot here if it has no water or sewer?
Yes. Lots with no water, sewer, or road work can still be sold for cash. Someone who later builds needs a district well-construction permit and, unless a sewer tap exists, a septic permit from the local health department. We check utilities, access, and title on every parcel before offering. The only contingency is our land inspection, and a failed inspection costs the seller nothing.
Will a one-acre lot be allowed a conventional septic tank?
Not always. Inside the June 2025 Santa Fe plan, if central sewer is missing, a new system on an acre or less must be an enhanced system with a 65 percent nitrogen cut. In the Ichetucknee priority focus area, only about 40 acres of this county, that enhanced system is required on any lot size. A lot outside the plan line is not covered just because the county touches the basin. Tanks already installed are not forced by this plan version to add nitrogen equipment at repair. The local health department still accepts the permit packet.
Can I sell land here when the property tax is unpaid?
Yes. Get a payoff from the tax collector before you sign. The balance is delinquent on April 1, a three percent penalty is added, and a certificate is sold on or before June 1. That certificate is a lien, not a transfer of the land. A deed case is later: the collector describes a 22-month redemption window, and state law allows a tax-deed application once two years have passed from April 1 of the issue year. We cover closing costs. Liens or back taxes can be paid from the sale proceeds at closing, with your consent.
Do I need a survey before I can build on a vacant lot?
Yes, if you are pulling a building permit. The residential application lists a survey and a legal description as the first items for a building or addition permit. The site plan has to show the well and the septic tank, and wind calculations must cover at least 130 mph. The form addresses construction permitting, not a land transfer.
Can I close on Union County land from another state?
Yes. You can sign electronically, and the closing papers can be handled by mail. Payment can be by check or wire. About 95% of vacant-lot owners have a Florida mailing address, and about 5% list an address in another state. An independent title company still has to finish the title work, and that review is what sets the closing date.

Guides for your situation
- Selling Land With Boundary or Survey Problems
Land with a boundary or survey problem can still be offered for sale, but closing may depend on how the buyer, lender, and title insurer handle it. The contract and closing requirements determine whether a survey is needed. A fence does not by itself establish the record boundary. A survey can identify gaps, overlaps, occupation lines, and encroachments; a competing Florida title claim may require a quiet-title action.[1][6][7]
- How to Sell Land in a Flood Zone
Flood-zone land can be sellable and sometimes buildable. A FEMA flood zone describes mapped risk; it is not a building permit. The buyer must verify the current effective Flood Insurance Rate Map and any map changes, then ask the local floodplain administrator what elevation, floodway, coastal, permit, and design rules apply.[1][2][4] Vacant land itself is not covered by an NFIP policy; flood insurance covers qualifying buildings and contents, not land value.[5][6]
- Can You Sell Land With Back Taxes in Florida?
Yes. Florida land with back property taxes can often be sold if closing can redeem the tax lien before the tax-deed cutoff. With the seller's consent, the title company can use sale proceeds for the approved payoff. Move quickly: taxes generally become delinquent April 1,[1][2] and redemption ends once a tax-deed buyer makes full payment to the clerk.[4][7]

How we made this page
Parcel Buyers is a land-buying company based in Florida. We buy vacant land directly from owners and publish these local pages so owners can see what land in their area is doing before they sell, to us or anyone else. We count the tax-roll figures ourselves from state data, take local rules and fees from the official sources listed below, and use AI tools to help research and draft the text. Every number links to its source, and we update the page when the data changes.
Method and sources
Tax-roll figures cover all parcels in Union County. Source [1] is our own count of the Florida Department of Revenue's 2026 preliminary property tax roll: "vacant residential" means land-use code 000; lot sizes use the land square footage on the roll; values are the county property appraiser's just (market) value as of January 1, 2026; sale prices count only arm's-length sales of a single lot that was vacant when it sold and was still vacant on January 1, 2026 (bulk and multi-parcel deeds removed). Page updated October 2, 2026. The reviewed 2026 recorded-sale window runs from January through June 2026; unreviewed recent sales are excluded. Flood and springs-BMAP figures screen tax-roll parcel center points, not parcel boundaries. They are aggregate map screens, not flood-zone, insurance, buildability, elevation, septic, or permitting determinations.
