The inspection contingency is one of the most important protections a buyer has in a Washington real estate transaction. Here's how it works, what inspectors look for in PNW homes, and how to think about waiving it in a competitive market.

The inspection contingency is a clause in your purchase and sale agreement that makes your offer conditional on the results of a home inspection. In Washington, the standard form is NWMLS Form 35E — the Inspection Addendum. When your offer includes this contingency, you have a specified number of business days (commonly 10, though buyers can negotiate shorter or longer windows) to hire a licensed home inspector, complete the inspection, review the report, and decide what to do next. Your options at the end of the inspection period are: proceed as agreed (accepting the home as-is), negotiate with the seller for repairs or credits, or terminate the contract and receive your earnest money back. The contingency exists because home defects are not always visible during a standard showing. Foundation issues, plumbing failures, electrical hazards, mold behind walls, or a failing roof may not be apparent to a buyer walking through a staged, lit home on a sunny afternoon. A professional inspection surfaces what you cannot see so you can make an informed decision before your earnest money is non-refundable.
Once your offer is mutually accepted, the clock starts on your inspection contingency. Your buyer's agent will help you schedule a licensed home inspector — in the Seattle metro, same-week availability is typical, and most inspections take 2.5 to 4 hours depending on the home's size. You should attend the inspection in person; the inspector will walk you through findings live, not just hand you a 50-page PDF. The inspector's report documents everything they observed — from minor maintenance items to significant defects. After the inspection, you have the remainder of your contingency window to decide your response. Most buyers ask their agent to draft an Inspection Response (NWMLS Form 35R) requesting either repairs or a seller's credit. The seller can agree, counter-propose, or decline. If seller and buyer cannot reach agreement on inspection terms before the contingency deadline, the buyer can terminate and recover their earnest money. One practical note: some buyers use a shorter contingency window (5–7 days) in moderately competitive markets to make their offer more attractive to sellers, while still retaining the core protection of being able to walk away.
Pacific Northwest homes have a specific risk profile shaped by the region's climate and building stock. Rain is the dominant concern: inspectors look carefully at roof condition, gutters, downspouts, foundation drainage, crawl space moisture, and any evidence of water intrusion in basements or lower levels. The PNW wet season runs October through May and can reveal drainage failures that are invisible in August. Inspectors will also flag evidence of deferred maintenance on wood-framed structures — dry rot in sill plates, decking, or window casings is common in older PNW homes and can signal more extensive framing damage if left unaddressed. Seattle and Eastside homes built before 1980 may contain asbestos in insulation, floor tiles, or pipe wrap — inspectors flag these and recommend professional testing. Radon testing is increasingly common in the PNW, particularly in areas east of the Cascades and in basements with limited ventilation, though King County levels are generally lower than Eastern Washington. Sewer scope inspections are typically performed as a separate add-on and are strongly recommended for homes built before 1970 — cast iron and clay sewer lines degrade and can fail without warning, and a sewer replacement runs $10,000–$30,000.
After you receive the inspection report, work with your buyer's agent to prioritize findings by severity. Most inspection reports contain 30 to 60+ items ranging from 'suggest monitoring' to 'immediate safety concern.' The strategic question is: which findings are material enough to negotiate, and which are normal wear-and-tear you'd be expected to accept? In general, buyers have the most leverage negotiating on safety hazards (electrical panels, carbon monoxide, fire code issues), structural defects, major system failures (HVAC, water heater near end of life), and moisture damage with evidence of active water intrusion. Buyers have less leverage on cosmetic items, minor maintenance tasks, or deferred items that were visible during showing. Two negotiating approaches: request specific repairs (the seller completes work before close, you verify in the walk-through), or request a credit (the seller reduces the purchase price or provides a closing cost credit, and you arrange repairs after close on your own terms). Credits are generally preferred by buyers because they retain control of contractor selection and timing. If the inspection reveals something so serious that you would not buy the home at any price — a foundation failure, an undisclosed major structural issue — this is the moment to terminate, receive your earnest money back, and continue your search.
In a highly competitive market — spring Seattle, spring Bellevue, any multiple-offer situation — sellers prefer offers without inspection contingencies because they reduce risk and closing uncertainty. Some buyers waive inspection entirely to win. This is not inherently reckless, but it should be a deliberate, eyes-open choice rather than a reflexive bid-to-win move. The downside of a full waiver is significant: you own whatever the home reveals after closing, including a failed sewer line, active foundation movement, or undisclosed mold, with no recourse against the seller for conditions that were inspectable. A middle path used by experienced PNW buyers is the pre-inspection — scheduling an inspector before submitting your offer, at your expense ($400–$600), so your offer can be submitted without a contingency but with the information you need to make an informed decision. This approach works when the seller allows pre-offer access and the timeline is long enough. Another option is a 'seller warranty' or 'as-is addendum with seller disclosure review' — accepting the home without an inspection contingency while still reviewing the seller's required disclosure statement carefully. Sellers are legally required to disclose known material defects in Washington (Form 17). A thorough disclosure review, combined with a cash escrow reserve for unknowns, is a calculated risk posture that some buyers take in strong markets.
