Land due diligence checks 8 things that decide what a parcel can be used for: zoning and future land use, flood zone, access, utilities, wetlands and protected species, boundaries and title, environmental history, and taxes. Run the checks you can do from a desk first, before you pay for a survey or a Phase I.
Key takeaways
- Land has no building to inspect. The checks decide what the parcel can legally and physically support.
- Start with the checks that can end the deal and cost little: zoning, flood zone, and access.
- Count back from the contract's due diligence deadline. Surveys, a Phase I, and species surveys take time to schedule.
- Ask the seller what has already happened on the site. Clearing before surveys are finished can add permit steps.
What decides whether land works
A building shows its problems. A parcel hides them. The questions that decide value are about what the site can be used for, what it costs to prepare, and which agencies have to approve it.
Several of those answers are public and free. Pull them before you spend money on a survey, a Phase I, or a species survey. If a check turns up a red flag, you can negotiate, extend, or walk away while the contract's due diligence period is still open.
The checklist
| Check | What it decides | Where to look | Red flag |
|---|---|---|---|
| Zoning and future land use | Whether your intended use is allowed | The planning department of the jurisdiction where the parcel sits. The Pasco County Property Appraiser lists that jurisdiction in the parcel's legal description | The use needs a rezoning, a variance, or a land use plan amendment |
| Flood zone | Insurance cost, lender requirements, and buildable area | The FEMA flood map for the parcel. Zones beginning with A or V are high risk | Most of the buildable area sits in a high-risk zone |
| Access | Whether the site can be reached legally and built on | Recorded easements and the survey. On a state road, FDOT's connection permit rule (Rule 14-96) | No recorded legal access, or no permit path for a driveway on a state road |
| Utilities | Development cost and timing | The utility that serves the parcel. For septic, the county health department | Lines are far from the site, or availability is not confirmed in writing |
| Wetlands and protected species | Usable acres and permits | Southwest Florida Water Management District for Environmental Resource Permit triggers. FWC for gopher tortoise permits | Wetlands on the site, or a burrow survey that finds tortoises |
| Boundaries, survey, and title | What you are actually buying | A title commitment and a boundary survey | Encroachments, unrecorded easements, or liens |
| Environmental history | Contamination liability | A Phase I environmental site assessment under the EPA's all appropriate inquiries standard | A recognized environmental condition in the report |
| Taxes | Carrying cost after closing | The Pasco County Property Appraiser and the tax collector | The assessment resets at sale, or an agricultural classification ends when your use begins |
Order and timing
- Desk checks first. Pull the parcel record, identify the jurisdiction, request a zoning verification letter, check the flood zone, and ask the utility for written availability.
- Title commitment and survey. Order both early. They show easements, access, and boundaries that change what the parcel can hold.
- Specialist work. A Phase I, a burrow survey, and any wetland review take scheduling time. Order them as soon as the desk checks look workable.
- Lender and valuation. If you are financing, find out what the lender requires. See broker opinion of value for how a BOV differs from an appraisal.
Read the contract's due diligence deadline and count back from it. Put any extension in writing before the deadline passes.
Wetlands, protected species, and permits
The Southwest Florida Water Management District says an Environmental Resource Permit is needed when a project disrupts wetlands, encroaches on a floodplain, changes stormwater runoff, or contributes to water pollution. Site grading and building a subdivision or a business are among its examples. Ask the District's service office what applies to the parcel.
If a site has gopher tortoise burrows, the Florida Fish and Wildlife Conservation Commission (FWC) is involved. It issues a 10 or Fewer Burrows permit for small projects and a Conservation permit for sites with more than 10 burrows. FWC no longer issues incidental take permits. A Disturbed Site permit may be needed if ground was disturbed before surveys and relocation were finished, so ask the seller whether any clearing has already happened.
Access, utilities, and septic
Access has two parts: a legal right to reach the parcel and a physical way to build the driveway. For a parcel on a state road, FDOT's Rule 14-96 governs State Highway System connection permits, and applications go through FDOT's One Stop Permitting system.
For utilities, ask the provider that serves the parcel for written confirmation of water and sewer availability and what connection will cost. Where sewer is not available, the county health department handles septic permitting in Pasco County.
What to ask the seller for
- The most recent survey and any title policy
- Environmental reports, soil tests, and wetland or species studies
- Utility letters, permits, and correspondence with any agency
- Recent tax bills, and any agricultural classification
- Leases or licenses on the land, such as farming, hunting, or signs
- Well and septic records, if any

Common questions
How long should the due diligence period be for vacant land?
The contract sets it, so set it from the longest lead time. A parcel that needs a Phase I, a survey, a species survey, and a utility letter needs more time than one that clears the desk checks. Put any extension in writing.
Who tells me what I can build on a parcel?
The planning department of the jurisdiction where the parcel sits. The Pasco County Property Appraiser says zoning and future land use are managed by that jurisdiction, which is listed in the parcel's legal description. Ask for a zoning verification letter.
Do I need a survey for vacant land?
A boundary survey shows boundaries, easements, encroachments, and flood zone lines. Ask your lender what survey it requires, and order it early because it feeds several other checks.
Will my property taxes change after I buy?
Florida reassesses non-residential property at just value as of January 1 after a change of ownership or control (s. 193.1555). An agricultural classification ends when the land is diverted to a non-agricultural use (s. 193.461). Ask the Property Appraiser what your bill would look like.
