The first things a competent visit gets right
Inspection requests from Seattle are routed to independent licensed professionals who already cover King County and reach Mercer Island on the same run. Where inspection is permitted work, the permit is pulled with Seattle Department of Construction and Inspections (SDCI) by the licensed contractor, not by the homeowner. Roughly 64 ZIP codes fall inside the Seattle routing boundary, and a metro that size usually has several contractors bidding on this work. The statewide view of plumbing inspection explains the job in full, and Seattle is one of 68 markets served by licensed plumbers in Washington. Published ranges are on the inspection costs page.
- 1

Before you sign
What to ask a Seattle contractor first
- 01
Which areas are excluded — crawl space, attic, below-slab piping or anything behind finished surfaces — so gaps are understood upfront?
- 02
Are static pressure and water heater age, venting and relief valve condition all documented, because those drive near-term expenditure?
- 03
Would the same contractor bid on the repairs found, since that arrangement can create an incentive to overstate defects?
Before anyone touches a pipe
Verify the license. It takes two minutes.
- Who licenses the work: Washington State Department of Labor & Industries (L&I).
- Who pulls the permit: Seattle Department of Construction and Inspections (SDCI) — the licensed contractor, never the homeowner.
- What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Inspection in Seattle — common questions
Is a plumbing inspection worth it when buying a house?
On an older property, usually yes — a general home inspection is visual and rarely includes a sewer camera. The two findings that most often justify the cost are a failing sewer lateral and an obsolete supply pipe material, both of which are large numbers.
Does a plumbing inspection include a sewer camera?
Not by default. Ask explicitly, because the sewer lateral is where the expensive surprises live.
How long does an inspection take?
For a typical single-family home, commonly one to a few hours depending on size, access and whether a camera inspection is included.
Do I need a permit for plumbing work in Seattle?
Permits in Seattle are issued by Seattle Department of Construction and Inspections (SDCI). As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
Are night and weekend calls handled differently in Seattle?
Requests route around the clock, but most contractors price after-hours work differently. Ask for the after-hours rate and a committed arrival window before agreeing to a dispatch.
What information speeds up a inspection callback?
Three things: where the water or problem is showing, whether the supply is shut off, and the property type — slab, crawl space or basement. With those, a pro covering Seattle can triage the urgency and bring the right parts.
How should a inspection quote be compared?
Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.
Who handles the permit for inspection in Washington?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.
