Pest Inspections in South San Francisco, CA

101 Exterminators performs pest inspections in South San Francisco for escrow, refinancing and pre-listing, issuing state-compliant WDO reports under SPCB Lic. #9119. Most of this housing came out of the post-war tract wave and the downtown blocks go back before 1940, so an inspection in this city is rarely a formality. We inspect the accessible structure, photograph every finding, and separate Section 1 from Section 2 in writing.

What a Lender Wants Out of a Post-War Tract House Is the Section 1 List

A California WDO report splits findings into two categories, and that split drives the transaction. Section 1 is active infestation or existing damage. Section 2 is a condition likely to lead to infestation — wood-to-soil contact, a leaking shower pan, earth-filled porch steps, inadequate sub-area ventilation. Lenders and escrow generally turn on Section 1. Once those items are done, the Notice of Work Completed is the document your agent is waiting on.

South San Francisco's geography shows up directly in the findings. On the fog side, through Westborough, Buri Buri and Winston Manor, reports skew toward subterranean evidence and fungus damage in sub-areas that stay damp long after March. On the warmer bay-facing slopes below Sign Hill they skew toward drywood damage in eaves, rafter tails and window headers. Downtown, where framing dates before 1940, we find both plus decades of patchwork repair.

Access is the practical constraint. A report covers what is accessible, and in this city that gets limited constantly — a sub-area hatch behind a packed garage, an attic scuttle inside a full closet, a crawl space too shallow to enter, a deck skirt with no removable panel, a locked side gate on a narrow lot. Every inaccessible area is noted as such. On a transaction clock, clearing access before we arrive is the easiest thing a seller controls.

How We Work in South San Francisco

We inspect all accessible structural wood — attic framing, the sub-area, sill plate, exterior siding and trim, decking, fencing and garage framing — and check for drywood and subterranean termites, wood-decay fungi and conducive conditions. In South San Francisco we make a point of getting into the sub-area on the fog side of town and onto the roofline on the bay-facing slopes, because that is where each half of the city hides its findings. The report goes out with photographs, exact locations, and Section 1 and Section 2 called separately.

South San Francisco Climate

South San Francisco has a coastal fog climate similar to Daly City but slightly warmer on the eastern slopes facing the Bay. The San Bruno Mountain ridgeline deflects some marine influence from the western residential areas. Soil moisture remains elevated year-round from fog drip and winter rains averaging 18–22 inches annually.

Housing Stock

Post-WWII housing dominates — 1940s–1960s wood-frame tract homes across the residential hillside neighborhoods. These structures are 60–80 years old and have had significant cumulative termite exposure. The older downtown-adjacent areas have some pre-1940 construction. Commercial and biotech corridor construction is modern.

Why Local Expertise Matters

South San Francisco's mid-century housing stock and coastal fog exposure create a specific termite risk profile. We understand the crawl space issues common in these homes and provide SPCB-licensed (#9119) inspection and treatment with WDO reports accepted for local real estate transactions.

We inspect all accessible structural wood including attic framing, crawl space, exterior siding, decking, fencing, and garage framing. We check for both drywood and subterranean termites, carpenter ants, fungi and wood decay, and conducive conditions such as wood-soil contact, excessive moisture, and improper drainage. Our written report clearly identifies Section 1 conditions (requiring treatment) and Section 2 conditions (requiring further investigation or preventive repair) with photographs.

Pest Inspections FAQs for South San Francisco

Our South San Francisco sale is in escrow and the report came back with Section 1 items — what does that mean?

Section 1 means active infestation or existing damage, and it is usually the part a lender or escrow requires cleared before closing. In this city that is often subterranean evidence or fungus damage in a damp sub-area, or drywood damage in eaves on the bay-facing slopes. Section 2 items — wood-to-soil contact, poor sub-area ventilation, a leaking shower pan — are conditions that could lead to infestation and are more often negotiated than required. Once the Section 1 work is finished we issue the Notice of Work Completed.

Should we get a pest inspection before listing a house in Buri Buri?

Yes, if you want control of the findings instead of a renegotiation. A pre-listing WDO report tells you what the Section 1 items are while there is still time to schedule the work, and on the 1950s and 1960s Buri Buri tract houses those items are commonly sub-area moisture damage or subterranean evidence at the stem wall. Buyers discovering the same things mid-escrow turns a scheduling question into a negotiation on their timeline.

Does a WDO inspection cover the garage and the fence on a South San Francisco lot?

Accessible structural wood gets inspected, and on these lots that normally includes the attached or detached garage, the sub-area, exterior trim, decking and wood fencing where it contacts the structure or the soil. Detached garages on the older downtown lots are frequently where the first Section 1 item turns up, because they were built without the moisture detailing the house got. Anything we cannot reach is written up as inaccessible rather than passed over.
