Two county milestones sit between a signed contract and your keys, and neither one is about your house. The plat for your phase has to be approved and recorded, and the subdivision’s roads, drainage and utility lines have to pass final inspection and be scheduled for the county’s acceptance. In unincorporated Polk County, the Land Development Code blocks the certificate of occupancy on any occupiable structure in a development until that second milestone is met.
Who approves the plat, and when it reaches the public record
A to-be-built contract in a new phase usually describes a lot and block in a named subdivision. That description enters the public record when the plat is recorded, and not before. Under the 2026 Florida Statutes, section 177.071(4) requires a plat to be administratively approved before it is offered for recording, with evidence of that approval placed on the plat itself, and section 177.111 then directs the circuit court clerk to record it on submission.
Jurisdiction follows the boundary rather than the mailing address. Section 177.071(4) gives a county exclusive authority over a plat lying wholly in its unincorporated area and a municipality exclusive authority over a plat lying wholly inside city limits. A Davenport or Haines City mailing address does not settle which government reviews your phase, so ask first whether the land sits inside a city or in unincorporated Polk County.
State law keeps the review itself from being open ended. Section 177.071(2) requires written acknowledgment of a plat submittal within 7 business days, naming any missing items and the timeframes that apply, and section 177.071(3) requires a decision inside that stated timeframe.
Polk County approves a plat one of two ways
Section 806 of the Polk County Land Development Code, last amended by Ordinance 2026-024 on April 21, 2026, sets out in subsection A the two conditions under which a plat can be approved. The first is that all private improvements have been installed and approved and all public improvements have been installed and accepted by the county. The second applies when those improvements are not finished, and it requires the applicant to post security under Section 909 instead. Where that assurance is a condition of plat approval, section 177.071(1)(d) of the statutes requires the county to accept commonly used forms, including performance bonds, letters of credit and escrow agreements.
That second route carries the document package in Section 806.B.4.b: a title certification effective within 45 calendar days of final approval, a subdivision agreement, an engineer’s certificate, the subdivider’s guarantee, a cost estimate, performance security and maintenance security. Section 806.C.3 adds a limit worth knowing. Approving the plat and the dedications shown on it does not amount to the Board of County Commissioners accepting the infrastructure or its maintenance, which takes a separate acceptance process.
Section 177.081(3) of the statutes says the same from the state side. Once a plat with the required dedications is approved and recorded, the streets, easements and public areas on it are deemed dedicated to the public, and nothing in that section obligates the governing body to build or maintain anything inside them unless it voluntarily takes that on.
What the subdivision security covers, and who it answers to
Section 909 sets the amounts. Performance security runs at 110 percent of the estimated total construction cost identified by the engineer of record and approved for accuracy by the county engineer. Maintenance security runs at 10 percent of the construction cost of improvements dedicated to Polk County, is held for twelve months, and has to stay effective for at least eighteen months from the date the Board accepts the improvement, extendable by the county engineer to a maximum of five years where special conditions make normal inspection and testing insufficient to assure structural integrity.
Running the formula shows the scale. On an engineer’s cost estimate of $2,400,000, the performance security is $2,640,000, and if $1,500,000 of that work is dedicated to Polk County, the maintenance security on it is $150,000. Those figures are arithmetic on the code’s percentages rather than a quoted price for any real subdivision.
| What happens | Improvements finished first (LDC 806.A.1) | Plat recorded on security (LDC 806.A.2) |
|---|---|---|
| Condition for plat approval | Private improvements installed and approved, public improvements installed and accepted | Performance security plus a subdivision agreement, engineer’s certificate, cost estimate and maintenance security |
| Who holds the remedy if work stalls | Not applicable, the work is done | Polk County, as the obligee on the bond, not the individual lot buyer |
| Risk to your certificate of occupancy | Low, the infrastructure gate in 909.A.7 is already satisfied | Real, your home’s certificate waits on infrastructure in the rights-of-way and easements |
| Document to ask for | Recorded plat book and page | Recorded plat plus the subdivision agreement’s construction completion date |
The sentence in Section 909 that decides your closing date
Subsection 909.A.7 is the provision to read before you sign. A certificate of occupancy will not be released on any occupiable structure within a development until all required infrastructure in the public rights-of-way and easements is completed, approved through satisfactory final inspection, and scheduled for the Board’s acceptance. Your builder can finish your house, pass its own inspections, and still be unable to deliver a certificate because a drainage structure or a stretch of road in the phase has not cleared final inspection.
The county’s own form documents the release. The Subdivision Agreement template Polk County publishes for this purpose, checked on November 10, 2026, commits the county to issue a letter of compliance allowing the release of certificates of occupancy once the applicant submits the required record drawings and the Land Development Division acknowledges that the necessary inspections are complete. The same template carries a construction completion date, an extension mechanism requiring a new instrument for the extended period, and a default clause under which the county uses the security and no further permits or approvals are granted for the project until adequate progress is shown.
Section 909 backs that with a deadline of its own. If the infrastructure has not passed final inspection within 60 days of the security’s expiration, a new security has to be issued or the county may call the existing one and finish the work itself.
Your lot corners may not be set when you close
Section 177.091(9) of the statutes treats monumentation differently depending on whether the local government bonds subdivision improvements. Where a county does not require improvements and does not accept bonds or escrow accounts, monuments have to be set at the lot corners before the lot is transferred. Where a county does require improvements and has a means of ensuring their construction, such as bonding, monuments have to be set before the bond or other surety expires. Polk County bonds. A staked corner at closing is therefore a contract term to negotiate rather than a guarantee the statute hands you, and Section 909 calls for the surveyor’s certificate of installation 45 calendar days before a performance security is released.
What to verify before you sign in an unplatted phase
- Confirm whether the parcel sits in unincorporated Polk County or inside a municipality, because that decides who approves the plat under section 177.071(4).
- Ask the builder which condition in Section 806.A the phase is using. The answer tells you whether the infrastructure is finished or bonded.
- Search the Polk County Clerk’s official records by plat book and page for your phase. If the plat is not there, your lot and block description is not yet of record. The county’s Accela Citizen Access portal carries the development records behind it.
- Get the construction completion date written into the subdivision agreement, then compare it with the closing date your purchase contract contemplates.
- Ask whether the Land Development Division has issued the letter of compliance for your phase. That document releases certificates of occupancy.
- Put lot corner staking in the contract in writing if you want it before closing.
Questions we get next
How do I find out whether my phase’s plat is recorded?
Search the Polk County Clerk’s official records by plat book and page, or by the subdivision name, using the Clerk’s online search, which indexes plats among its recorded documents. Then check the county’s Accela Citizen Access portal, which carries the development records the Land Development Division processes.
If the roads are not finished, can I make a claim on the subdivision bond?
No. Polk County’s performance bond template names the county as obligee, and on default the surety’s obligation runs to completing the improvements and paying the costs, including engineering, legal and contingent costs. Section 909 adds that until the Board of County Commissioners accepts the improvements, maintaining them remains the applicant’s sole responsibility.
Can the builder commit to a closing date before the plat records?
That is a contract question, and the answer separates two timelines. Your home’s construction schedule belongs to the builder. Plat recording and the infrastructure gate in 909.A.7 belong to the county and to the developer’s completion schedule under the subdivision agreement. Ask for both dates in writing, and ask what the contract says happens if the second one moves.
Where to go from here
Everything above is checkable before you sign, and all of it is cheaper to check then. The same holds on the tax side, where a first Polk County tax bill on a new home covers the land only, and on the school side, where zoning for a new address depends on the district’s locator rather than the sales office. Where the phase has a community development district, who controls that district and the association board runs on its own timeline.

We read the plat status, the subdivision agreement dates and the contract’s completion language together, because those three documents decide whether the closing date in front of you is realistic.
