Asbestos Testing & AHERA Surveys in Spokane, WA
In Spokane County the survey is not a precaution; it is the first required step. Spokane Clean Air's rule is that an asbestos survey must be conducted by an AHERA-certified Building Inspector prior to renovation or demolition activities, and a copy must be posted in a readily accessible and visible area at the work site at all times. Washington L&I requires a good faith inspection statewide before any construction, renovation, remodeling, maintenance, repair or demolition project. This site coordinates surveys through accredited inspectors and analysis through accredited laboratories, one of which is in Spokane Valley. Below: what the survey is, how sampling works, and what it costs by published ranges.
An AHERA survey is a documented inspection of a building for asbestos-containing material. The inspector walks the whole area the project will touch, identifies each suspect material -- flooring, mastic, ceiling texture, joint compound, pipe wrap, siding, roofing -- and takes physical samples of each. An accredited lab reports whether asbestos is present and in what form. The report is the document Spokane Clean Air wants posted at the job site. It lists each material, its location and condition, whether it is friable or nonfriable, the lab result for each sample, and the quantity in square or linear feet. Those quantities set the Notice of Intent tier and the notice period, so a survey that guesses at quantity costs money later. The report stays with the property.
Sampling has a logic to it. Asbestos was not mixed evenly into products, so one sample of a ceiling or a floor can miss what a second finds; an inspector takes more than one sample of each material and treats the material as positive if any sample is. Layers matter: vinyl over older vinyl over black mastic is three materials, not one, and each gets sampled. Lab turnaround is set by the lab, so ask for the expected date before scheduling a contractor. The alternative to sampling is assumption: an owner can treat a material as asbestos-containing without testing it and have it removed as such. That rarely makes sense for a house full of ceilings, where a negative result would let an ordinary drywall contractor do the work and a positive result changes the whole cost.
Situations that trigger a survey in Spokane County
A survey is required before any contractor renovation or demolition that disturbs more than bare wood, metal or glass. Spokane Clean Air's own examples are broad; these are where the rule shows up.
- Remodeling a residence or other building, inside or out, in Spokane Clean Air's words; a South Hill kitchen counts as fully as a warehouse.
- Replacing, repairing or disturbing flooring, wall, ceiling, siding or roofing materials, or heating, plumbing or electrical systems, the lists on the agency's guidesheet.
- Listing a pre-1980 house for sale, with the question answered on paper before a buyer's inspector raises it.
- A rental turnover with damaged floor tile, ceiling texture or pipe wrap, since rental work must be done by a certified contractor.
- Fire damage: the county's transfer stations cannot accept demolition building materials from the fires without a clean asbestos test.
Spokane Clean Air puts it bluntly: if no survey has been performed, it is likely that asbestos requirements are not being met. The survey rule guide covers the full rule, the exemptions and the fee ladder.
How an AHERA survey is done
The survey is shaped by the project, so the first thing the inspector needs is the plan. A kitchen remodel gets a survey of the kitchen and whatever the work will pass through; a whole-house teardown gets a survey of the whole structure, because demolition disturbs everything, and that is the survey the demolition NOI and the demolition page depend on. The inspector walks every space the plan touches and needs access to the parts nobody looks at: the attic hatch, the crawlspace, behind the furnace, the edge of the carpet where the old floor shows. Clearing those spots ahead of time is the owner's one job. Each suspect material is named and sampled by taking a small physical piece, which leaves a coin-sized mark that a finisher patches later.
Samples are bagged, labeled and logged, then go to an accredited laboratory on the lab's turnaround. A survey covers what is accessible and what the inspector was told about. A good report says what was not sampled and why, so that when a wall comes down and a second layer of flooring appears, everyone knows it was outside the survey rather than missed. Washington L&I puts one duty on the exempt owner-occupant: you must still provide relevant information to contractors and other workers you bring in. The survey report is that information, in a form a contractor can post at the job site as Spokane Clean Air requires.
Reading the survey report
Sort the results table into three groups: sampled and positive, sampled and negative, and assumed. Assumed materials were never sent to a lab and are treated as asbestos-containing by choice; they are removed and filed as such. For a large assumed material, a ceiling or a floor, ask whether sampling would cost less than abating. Next, the friable or nonfriable label on each positive, which changes what the rules ask for. Spokane Clean Air's filing rules exempt removal of only caulking, nonfriable window glazing and nonfriable roofing from the Notice of Intent, while friable materials such as pipe wrap, sprayed texture and attic fill need the tightest containment. Then find the quantities, in linear feet for pipe and square feet for surfaces.
Add them up per structure and set them against the filing line of 10 linear feet or 48 square feet, then against the tier lines at 259 linear or 159 square feet and at 999 linear or 4,999 square feet. Condition notes come last, and they map onto EPA's guidance: material in good condition that will not be disturbed should be left alone. A positive in good condition outside the project area can stay; a damaged positive inside it cannot. The report is not a Notice of Intent, a permit or a clearance; it is the input to all three. Keep it with the house records; a copy is posted at the work site at all times, in Spokane Clean Air's words, while the work runs.
Clearance and air testing after removal
Clearance has two halves, and the order matters. The visual half comes first: with the containment still up and the negative air unit still running, an inspector looks at every surface inside for residue, dust or leftover material. Air testing a room that fails the visual is a wasted lab fee, so the room is cleaned again until it passes by eye. The air half follows: sampling pumps draw room air through filter cassettes, the cassettes go to a laboratory, and the containment stays sealed until the result is back. The scope should name three things about clearance: who performs it, which laboratory reads it, and what happens on a fail. A fail is not a crisis; it means the room is cleaned again and sampled again with the sheeting still in place.
What it must never mean is that the sheeting comes down first. Having clearance done by someone other than the contractor who did the removal keeps the check independent, and the inspector who wrote the survey already knows the building. The clearance report is the last document in the set: survey, Notice of Intent, lab results, clearance, manifest. It is the one that says the work was finished rather than started, which is the question a buyer asks. Clearance is also where an abatement job hands off to ordinary trades: the drywall finisher, the flooring installer and the painter come in after the result, not before, and the negative air unit is the last piece of equipment to leave.
Selling or buying a pre-1980 house in Spokane
Spokane Clean Air's survey rule is triggered by renovation or demolition, not by a sale. What makes the survey part of a Spokane sale is arithmetic: 68.3% of the housing units inside the city were built before 1980 and most buyers of those houses plan to change something, so the first contractor they hire needs an AHERA survey before touching anything other than bare wood, metal or glass. For a seller, the useful move is to gather what already exists: any past survey, lab results, Notice of Intent records, clearance reports and disposal manifests from earlier work. If a textured ceiling was covered with new drywall rather than removed, say so; the material is still there, and the next owner should not drill into it without knowing. A seller who removes something before listing follows the full sequence, survey first, and the NOI and clearance records join the sale file. For a buyer, budget the survey as part of due diligence on any pre-1980 house with a remodel in mind.
Published national ranges put testing at $250 to $850; the report sets the NOI tier and much of the cost of the first project. A buyer who will live in the house gets Spokane Clean Air's owner-occupied exemption for the buyer's own labor, with no NOI required for removal done by the resident owner. A house bought as a rental never gets it; every asbestos job there goes to a certified abatement contractor.
Which survey or test the job needs
Four kinds of testing come up in Spokane, and they are not interchangeable. The project decides which one the rules require.
Full AHERA survey
Required before any contractor renovation or demolition. Every suspect material in the project area is sampled and lab-reported, and the report is posted at the site and used for the Notice of Intent. It sets the NOI tier, and a future buyer can rely on it.
Targeted sampling of one material
Only when you own and live in the house and do the work yourself; Spokane Clean Air says that owner can do his or her own assessment. Sampling just the ceiling you plan to scrape is a version of that. Hire a contractor and the survey must come from an accredited AHERA Building Inspector.
Air clearance testing after abatement
Not a survey of materials but a check of the air inside the containment after removal, before the sheeting comes down. It shows the space is clean enough to reopen and belongs in every abatement scope, ideally performed by someone other than the removal contractor.
Pre-demolition survey
Required for the demolition Notice of Intent, which is itself required before the City of Spokane issues a demolition permit. It covers the whole structure, and the NOI for any demolition carries a 10-day notice and a $250 fee.
If the material will not be disturbed, no test is required and EPA's guidance is to leave it alone. If it will be, the survey comes first, and the abatement page describes what follows.
Asbestos Testing & AHERA Surveys FAQs
Is asbestos testing required in Washington state before a remodel?
Yes, in the form of a good faith inspection. Washington L&I's rule is that prior to any construction, renovation, remodeling, maintenance, repair or demolition project, homeowners, building owners and contractors must have a good faith inspection for asbestos. Work in your own residence, not used for commercial purposes, is exempt from the general survey requirement, though you must still provide relevant information to any contractors or workers you bring in. In Spokane County, contractor work also requires the survey to be performed by an accredited AHERA Building Inspector.
Where can I get an asbestos test done in Spokane?
Through an AHERA-certified Building Inspector who collects the samples and an accredited laboratory that analyzes them. Spokane Clean Air keeps a public list of asbestos service providers; as of September 2026 it carries 39 survey providers and 6 testing laboratories, one of them in Spokane Valley, with the agency's note that appearing on the list is not a recommendation. A homeowner working in an owner-occupied house can do his or her own assessment, which can mean sending samples to a lab directly.
Is a general home inspection the same as an asbestos survey in Spokane?
No. A home inspection report does not satisfy Spokane Clean Air's rule unless it was written by an AHERA-certified Building Inspector who sampled the materials and had them analyzed by a laboratory. The agency's requirement is specific: an asbestos survey must be conducted by an AHERA-certified Building Inspector prior to renovation or demolition activities, and a copy must be posted at the work site. A home inspector may point out a textured ceiling or a wrapped pipe as suspect, which is useful, but suspect is not a result. Only lab-analyzed samples turn a suspicion into the report a contractor can file the Notice of Intent from.
What happens if the asbestos survey comes back negative?
A negative result on every sampled material means the project is ordinary construction: no Notice of Intent, no certified abatement contractor, no containment. A drywall contractor can take down the ceiling and a flooring installer can pull the tile. Keep the report anyway. It is the document that shows the survey Spokane Clean Air requires was done, it is still posted at the work site while the work runs, and it answers the question for the next owner. Read the fine print too: a negative on the ceiling texture says nothing about the pipe wrap in the basement or any material the inspector listed as not sampled.
