What is a Washington WDO Inspection?

In Washington state, a termite inspection is typically conducted as a Wood-Destroying Organism (WDO) inspection. This is a standardized evaluation performed according to regulations set by the Washington State Department of Agriculture (WSDA) ¹. It's not just a casual look-around; it's a formal process with specific reporting requirements, especially during real estate transactions.

The primary goal is to provide a detailed snapshot of a structure's vulnerability to pests that consume or damage wood. The inspector is looking for three key things:

• Evidence of Active Infestations: Live insects, mud tubes (from subterranean termites), exit holes, frass (sawdust-like droppings), or audible clicking.
• Evidence of Past Damage: Wood that is hollowed out, crumbling, or shows visible tunnels, even if the pests are no longer active.
• Conducive Conditions: Environmental factors that attract or support WDOs, such as excessive moisture, wood-to-soil contact, poor ventilation in crawl spaces, and clogged gutters ^{2 3}.

When is a WDO Inspection Required?

The most common scenario requiring a formal WDO inspection is a residential real estate transaction. Most lenders will require a clear WDO inspection report before approving a mortgage ⁴. Even if not strictly required by your lender, it is a standard and highly recommended part of the buyer's due diligence.

Outside of real estate, inspections are wise for:

• Annual Preventative Maintenance: Especially for older homes or properties in areas known for damp conditions.
• After Suspecting an Infestation: If you see swarmers (winged reproductive termites), mud tubes, or unexplained wood damage.
• Prior to Major Renovations: To ensure the structural integrity of the wood you'll be building onto or enclosing.

The Washington Inspection Process: Rules and Standards

Washington has clear administrative codes (WAC) governing how these inspections must be performed and reported. Here's what you can expect:

Who Can Perform It? Only individuals licensed by the WSDA as Structural Pest Inspectors are authorized to complete official WDO inspection reports for real estate transactions ^{1 5}. These professionals have the training to identify subtle signs of infestation and damage.

Scope of the Inspection The inspector will conduct a thorough, visual examination of all accessible areas of the structure. This includes:

• The exterior perimeter, foundation, and siding.
• Interior rooms, attics, and garages.
• Crawl spaces and sub-areas (if there is at least 18 inches of clearance).
• Decks, fences, and other outbuildings on the property ^{2 3}.

It's important to understand that inspections are non-invasive. Inspectors do not tear into walls, move permanent storage, or cut into structural members. Areas that are inaccessible (e.g., behind finished walls, under immovable carpeting, in a crawl space with less than 18 inches of clearance) must be clearly noted as such on the report, indicating a potential vulnerability ⁶.

The Critical Report: ICN and Diagram The official report is the most important deliverable. In Washington, every WDO inspection report for a property transfer must include a WSDA-issued Inspection Control Number (ICN) ^{1 5}. This number tracks the report and the inspecting firm.

The report must contain:

1. Detailed Findings: A clear description of any WDOs found, evidence of damage, and conducive conditions. Any abbreviations used must be explained in a legend ^{7 8}.
2. A Diagram: A sketch that reasonably resembles the building's footprint, marking the specific locations of any findings and inaccessible areas ^{7 9}.
3. Clear Language: If no issues are found, the report must include prominent preventative language and be signed by the property owner ⁸.

Understanding Inspection Costs in Washington

The cost for a professional WDO inspection in Washington can vary. General estimates typically range from $100 to over $200, though the final price depends on several factors ^{5 10 11}.

• Property Size and Complexity: A large, multi-story home with multiple outbuildings will cost more to inspect than a small, single-story rambler.
• Location and Accessibility: Properties in remote areas or with very difficult-to-access crawl spaces may incur higher fees.
• Bundled Services: Often, the WDO inspection can be bundled with a general home inspection, which may offer some cost savings.
• What the Fee Covers: The inspection fee covers the licensed inspector's time, expertise, and the completion of the official WSDA-compliant report with its unique ICN ¹².

It's advisable to get quotes from several licensed inspectors. Remember, the cheapest option may not provide the most thorough inspection. This report is a key tool in your real estate negotiation and a critical document for your lender.

Why This Inspection is Non-Negotiable for Home Buyers

Securing a WDO inspection is one of the smartest steps a home buyer can take. The report provides leverage and protection in several ways:

• Uncovers Hidden Issues: Termites and other WDOs can cause significant structural damage that is often hidden from the untrained eye during a walk-through.
• Informs Negotiations: If the inspection reveals active infestation or damage, you can use the report to request that the seller pay for treatment and repairs, or you may negotiate a lower sale price to cover the costs yourself.
• Protects Your Financing: As mentioned, most lenders require a clear report. A failed inspection with major findings can jeopardize your loan approval ⁴.
• Highlights Future Maintenance: The report on conducive conditions (e.g., poor drainage, earth-to-wood contact) serves as a to-do list for preventative maintenance once you own the home.
• Insurance Gap: Crucially, damage caused by termites and other pests is not covered by standard homeowners insurance policies ¹³. The inspection is your primary defense against bearing the full, unexpected cost of remediation.

After the Inspection: Treatment and Clearance

If the WDO inspection report indicates an active infestation or damage, the next step is to hire a licensed pest control professional to perform treatment. Treatment options vary based on the pest and the construction of the home.

Once treatment is completed, you can request a WDO Re-inspection or Clearance Letter. This is a follow-up inspection, often by the original inspector, to verify that the treatment was successful and that the active infestation noted on the original report has been addressed. This clearance letter can then satisfy lender and buyer concerns, clearing the path for the sale to proceed.

Finding a Qualified Professional

When searching for a WDO inspector, always verify their WSDA Structural Pest Inspector license. Look for established companies with strong local reputations and clear sample reports. Ask about their inspection process, what their fee includes, and how quickly they can provide the official report with the WSDA ICN. Reading reviews and asking for recommendations from your real estate agent are excellent ways to find reliable service.
