Wood-Destroying Organism (WDO) Reports in Florida: Purpose and Process

Wood-Destroying Organism (WDO) reports are formal inspection documents that identify the presence, absence, or evidence of organisms capable of structurally damaging a building. In Florida, these reports carry significant weight in real estate transactions, insurance evaluations, and construction permitting. Understanding their purpose, regulatory basis, and procedural requirements helps property owners, buyers, and real estate professionals navigate the process with clarity.

Definition and scope

A WDO report — sometimes called a termite inspection report or Form DACS-13645 — is a standardized document produced by a licensed pest control operator following a visual inspection of a structure. The Florida Department of Agriculture and Consumer Services (FDACS) regulates this process under Florida Administrative Code Rule 5E-14.142, which defines the required format, inspection procedures, and disclosure requirements.

The organisms covered under Florida's WDO classification include:

1. Subterranean termites (including Reticulitermes spp. and the invasive Coptotermes formosanus)
2. Drywood termites (Cryptotermes spp. and Incisitermes spp.)
3. Wood-boring beetles (including old house borer and powder post beetles)
4. Wood-decay fungi (wet rot and dry rot organisms that degrade structural wood)

The scope of a WDO report is limited to visible and accessible areas of a structure at the time of inspection. Concealed spaces — such as areas behind finished walls or beneath sealed flooring — are explicitly outside the inspection boundary unless access is available. This limitation does not reflect on inspector competency; it is a structural characteristic of the report type itself.

Scope and geographic coverage: This page addresses WDO report requirements as they apply under Florida state law and FDACS jurisdiction. Federal inspection standards, reports prepared under U.S. Department of Housing and Urban Development (HUD) guidelines for federally backed loans, and regulations in adjacent states such as Georgia or Alabama are not covered here. Multi-state property portfolios or federally regulated housing projects may be subject to requirements beyond Florida's Rule 5E-14.142.

How it works

The WDO inspection and reporting process follows a defined sequence under Florida administrative rules.

Step 1 — Licensing verification. Only a licensed pest control operator holding a category designation under Florida Statute §482 may conduct a WDO inspection and sign Form DACS-13645. The operator must hold a Category 7 (Wood-Destroying Organisms) license or work under the direct supervision of a Category 7 licensee.

Step 2 — Visual inspection of accessible areas. The inspector examines the exterior perimeter, interior spaces, attic (if accessible), crawl space (if applicable), garage, and all visible wood members. The inspection is visual only — no destructive probing or specialized equipment is mandated by Rule 5E-14.142, though inspectors may use moisture meters or borescopes at their discretion.

Step 3 — Report completion on Form DACS-13645. The form requires the inspector to record:
- The address and date of inspection
- Species or organism type identified (if any)
- Whether live infestation, previous infestation, or damage was observed
- Areas of the structure inspected and any areas not inspected
- Existing conditions that may promote WDO activity (e.g., wood-to-soil contact, moisture intrusion)

Step 4 — Distribution. Florida Administrative Code Rule 5E-14.142 requires the original report to be provided to the party who ordered the inspection, with a copy retained by the pest control company for a minimum of 3 years.

The regulatory framework governing this process is detailed in the regulatory context for Florida pest control services, which covers FDACS authority, licensing structures, and enforcement mechanisms.

Common scenarios

WDO reports appear in four primary contexts in Florida:

Real estate transactions. The most frequent trigger for a WDO report is a residential or commercial property sale. Lenders financing with VA loans require a WDO report; FHA loans require one when the appraiser notes visible evidence of infestation. Conventional loan requirements vary by lender. Florida real estate contracts commonly include a WDO contingency clause, allowing buyers to renegotiate or withdraw based on report findings.

New construction pre-treatment compliance. Florida Building Code Section 1816 requires pre-construction soil treatment or physical barriers for new structures in areas of termite activity — which, in practice, encompasses the entire state. The Florida new construction pest prevention process often concludes with documentation that parallels WDO reporting standards.

Post-treatment verification. After a fumigation or localized treatment for drywood or subterranean termites, a follow-up WDO report may be ordered to document clearance. This is distinct from a warranty certificate issued by the treating company. For drywood termite treatment specifics, see Florida Drywood Termite Treatment Options.

Insurance and refinancing reviews. Some property insurers and mortgage servicers require updated WDO reports — typically no older than 30 days at closing — as a condition of policy issuance or loan modification.

Decision boundaries

Understanding what a WDO report can and cannot establish helps prevent misinterpretation.

WDO report vs. home inspection. A licensed home inspector operating under Florida Statute §468, Part XV, performs a broader structural and systems evaluation. A WDO report is narrower — it addresses only organisms within the defined classification. The two documents are complementary, not interchangeable.

Active infestation vs. prior damage. Form DACS-13645 distinguishes between three findings: live/active infestation, evidence of previous infestation (no live activity observed), and visible damage without confirmed source. Each carries different implications for remediation urgency. Active subterranean termite infestation, for example, typically requires treatment within a shorter window than a prior-damage-only finding.

Visible evidence vs. absence certification. A WDO report cannot certify that a structure is free of wood-destroying organisms — only that no evidence was observed in accessible areas at the time of inspection. This distinction is explicit in Rule 5E-14.142 and printed on Form DACS-13645 itself.

Florida-specific organisms. The state's subtropical climate creates year-round pressure from the Formosan subterranean termite (Coptotermes formosanus), which FDACS and the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) identify as among the most economically damaging termite species in North America. WDO reports in South Florida, where Formosan pressure is highest, carry heightened significance compared to reports from cooler northern counties.
