Pest Inspections in San Francisco, CA

WDO Reports · Section 1 & 2 · Real Estate · General Assessment

Whether you're buying or selling a home, refinancing, or simply want to know the pest health of your property, a California Structural Pest Control inspection provides a documented, licensed assessment of current infestations, wood damage, and conditions that could lead to future infestation. 101 Exterminators issues state-compliant Wood Destroying Organism (WDO) reports accepted by all California lenders, escrow companies, and real estate agents.. Serving San Francisco and surrounding San Francisco County.

Why San Francisco Homes Need Inspections Services

In California's real estate market, a clean pest report is often a condition of sale or financing. Both buyers and sellers frequently need WDO reports — buyers to understand what they're purchasing, sellers to disclose and address issues proactively before listing. In Central California's coastal markets (Monterey, Santa Cruz), high termite pressure and older housing stock mean that a significant percentage of homes have Section 1 or Section 2 conditions that affect transactions.

Drywood termites in pre-1940 framing are the dominant concern. Subterranean termites active in fog-belt soil. Real estate transaction volume is among the highest in California — WDO inspections are a routine part of every property sale. Swarm season May–October for drywood; February–April for subterranean.

San Francisco Climate

San Francisco's marine climate — persistent fog, moderate temperatures, and year-round mild humidity — supports continuous termite colony activity without winter dormancy. Western neighborhoods (Sunset, Richmond) stay foggy and moist; eastern neighborhoods (Mission, Castro, Noe Valley) are warmer, favoring drywood termite swarm activity May–October.

Housing Stock

The city has approximately 20,000+ pre-1915 Victorian and Edwardian structures, many with original old-growth redwood and fir framing never comprehensively treated for termites. Row house configurations — where buildings share party walls — allow colony spread without typical swarming evidence. Post-1906 and post-WWII construction have separate but significant termite vulnerabilities.

Why Local Expertise Matters

San Francisco termite work is a specialty. Row house fumigation logistics, the city's pesticide ordinances, historic building treatment constraints, and the specific WDO reporting format expected by SF real estate agents all require local expertise. We hold SPCB License #9119 and have direct experience with these city-specific factors.

Pest Inspections FAQs for San Francisco

Who usually pays for the pest inspection in a real estate transaction?

In California, the buyer typically pays for the inspection when ordering it for their own protection. When the seller orders an inspection pre-listing or to clear conditions as a condition of sale, the seller pays. This is negotiable in the purchase contract. Inspection fees typically run $75–$200 for a standard residential inspection.

Do I need a pest inspection for a refinance?

VA loans in California require a pest inspection and clearance of all Section 1 conditions as a loan condition. FHA loans increasingly require pest inspections as well. Conventional loans may or may not require them depending on the lender and appraiser. Your loan officer can confirm the requirement for your specific loan.

What if the inspector finds active termites?

The inspector documents the finding in Section 1 of the report. Treatment options and costs are discussed separately — the inspection report and the treatment are two different engagements. You are under no obligation to use 101 Exterminators for treatment if we performed the inspection.
