A termite or WDO (wood-destroying organism) inspection is a separate, specialized report by a California-licensed structural pest control company that documents active infestation, past damage, and conditions that invite it. It is not the same as a home inspection – and in San Diego, where both subterranean and drywood termites are common, most buyers should arrange both.
Termite inspection vs. home inspection: two different reports
This is the single point that confuses most buyers, so let’s settle it first. A home inspection is a broad, visual evaluation of a property’s major systems – roof, structure, electrical, plumbing, HVAC, and more. A WDO inspection (often called a “termite inspection” or “Section 1/Section 2 report”) is a narrow, specialized examination focused only on wood-destroying organisms and the damage they cause.
Here is the part that matters legally: in California, termite and other wood-destroying pest work falls under the Structural Pest Control Act. Only a company holding a state structural pest control license can perform a WDO inspection, issue a Section 1 clearance, or treat for termites. A home inspector – even a highly experienced one – is not a licensed structural pest control operator and cannot legally produce that report or sign off on a clearance.
So what does that mean for you when you hire us? As your buyer’s home inspector, we examine the home thoroughly and will flag visible evidence we observe – mud tubes, frass (drywood termite droppings that look like coarse sandy pellets), damaged or hollow-sounding wood, and moisture conditions that attract pests. But when it comes to the formal WDO report your transaction may require, we coordinate with and refer you to a licensed pest control company. The two reports work together; neither replaces the other.
How a WDO (Section 1) inspection works
A licensed pest inspector walks the accessible interior and exterior, the attic, the subarea or crawlspace, the garage, and the foundation perimeter looking for wood-destroying organisms and the moisture problems that fuel them. The findings get organized into a standardized California report with a diagram of the structure, and conditions are typically sorted into two categories:
- Section 1 – active infestation or visible damage from wood-destroying organisms. Think live termites, fungus/dry rot, or wood already eaten or weakened. These are the items lenders and contracts most often require to be cleared.
- Section 2 – conditions that are likely to lead to infestation but where no active problem exists yet. Examples include earth-to-wood contact, excessive moisture, plumbing leaks near framing, or wood debris in the subarea.
“Wood-destroying organisms” is broader than just termites. In San Diego, a WDO report can also note fungus and dry rot – common around aging shower pans, leaky window flashings, and damp crawlspaces near the coast – as well as wood-boring beetles. A Section 1 clearance is the document issued after the noted Section 1 items have been treated or repaired and re-inspected.
Why San Diego homes are a termite hotspot
Two very different termites trouble San Diego County, and where you’re buying changes which one is more likely.
Subterranean termites live in the soil and build mud tubes up foundations to reach wood. They thrive where ground moisture is high – older homes with raised foundations and damp crawlspaces, properties with poor drainage, and irrigation that keeps soil wet against the structure. Inland and slope-built neighborhoods around Escondido, El Cajon, and Santee see plenty of conducive conditions.
Drywood termites need no contact with soil at all. They fly in, settle directly into dry structural wood, attics, eaves, fascia, and trim, and are extremely common along the coast from Oceanside through Encinitas, La Jolla, and Coronado. Their telltale sign is small piles of frass beneath tiny “kick-out” holes. Because they live entirely inside the wood, drywood colonies are easy to miss without a careful, close-up inspection.
Add San Diego’s older housing stock – mid-century and earlier homes with original framing, wood siding, and decades of accumulated moisture issues – and you can see why a WDO inspection is rarely wasted money here. If you’re considering an older home in one of the county’s established neighborhoods, treat the termite report as essential, not optional.
Why lenders and contracts ask for a termite report
You may run into a WDO report requirement even if you weren’t planning on one. A few common reasons:
- Loan program rules. Certain government-backed loans (such as VA financing) commonly require a clear termite report before closing. Conventional loans may require one when the appraiser notes evidence of wood-destroying pests.
- Purchase contract terms. Many California purchase agreements address who pays for the WDO report and any Section 1 corrections. This is negotiable – read your contract and lean on your agent.
- Plain risk management. Even when nobody requires it, termite damage can be expensive and is frequently hidden behind drywall, stucco, and finished surfaces. A report priced as a small fraction of repair costs is cheap insurance.
Because financing and contract deadlines move fast, it’s worth lining up your WDO inspection early – ideally alongside your general home inspection so both reports land within your inspection contingency window.
How we coordinate it into your inspection
When you book a buyer’s inspection with us, you don’t have to chase down a separate pest company on your own. Here’s the practical workflow:
- We perform your full general home inspection and note any visible evidence of wood-destroying organisms or moisture conditions we observe during our walkthrough.
- We help you coordinate a California-licensed structural pest control company to perform the formal WDO inspection and issue the Section 1/Section 2 report – often scheduled the same day for efficiency.
- You receive two complementary documents: our home inspection report on the home’s overall condition, and the licensed pest company’s WDO report. Reviewing them side by side gives you the clearest picture before your contingency expires.
To make sure nothing slips through the cracks, it helps to know what a general inspection covers on its own. Our San Diego home inspection checklist walks through every system we examine, and pairing that with a dedicated WDO report from a licensed operator closes the gap on pests.
A note on treatment and clearances
If the WDO report turns up Section 1 items, treatment and the resulting clearance must come from a licensed structural pest control company – again, not from a home inspector. Treatment options range from localized spot treatments to whole-structure fumigation (tenting) for widespread drywood infestations, and the right approach depends on the type and extent of activity. Your licensed pest operator will lay out the choices, costs, and what a clearance requires.
