What the city's own flood damaged list tells a Yonkers assessor
Asked by the county planners whether it keeps a record of flood damaged properties, the City of Yonkers answered yes and gave seven places: the Nepperhan River Valley, which is the Saw Mill River, the Hudson River, Clunie Avenue, Nepperhan Avenue, the Bronx River Valley, Tibbetts Brook and Harrison Avenue.

Ten square feet is where Article 32 starts. Labor Law section 930 counts something as a project only where the assessment, remediation or abatement covers more than that area, and it leaves out routine cleaning together with construction, maintenance, repair and demolition done for some purpose other than dealing with mold.

New York State Department of Health publication 7287 states that mold testing is not recommended and is not required by any regulatory agency, that there is no state or federal standard for mold in homes, that sampling can cost more than simply cleaning and repairing the water problem, and that knowing which species is present does not change the advice.

What a Yonkers inspection settles before anyone opens a wall
An inspection ends the guessing about a Yonkers basement: the measured area, the wet material behind the plaster, the water feeding it and who has to answer for it. Start with what the city already publishes. Asked whether it keeps a record of flood damaged properties, Yonkers said yes and named seven places, among them the Nepperhan River Valley, Clunie Avenue, Harrison Avenue and Tibbetts Brook. Five of the seven are inland watercourses or the streets beside them, so the useful first question is not how bad the stain looks, it is what your address sits over.
Book the scarce half first, then worry about the wall
Two Yonkers specifics should shape your timing. The state register holds 19 remediation licenses at Yonkers addresses against 8 assessment licenses, and the assessor is the half that has to go first and come back at the end, so that appointment is the one that fixes your dates. The other is the age of the stock: 22,653 of the city's 85,006 homes were built in 1939 or earlier, which makes an unlined masonry foundation the normal case rather than the exception, and it changes where the meter goes. And if the worst patch is smaller than a three foot by three foot square, say so when you write to us, because you may not need anybody.
Say what the street is
Yonkers names the Nepperhan Valley, Clunie Avenue, Nepperhan Avenue, the Bronx River Valley, Tibbetts Brook and Harrison Avenue on its own flood damaged list. If you are on one, the inspection starts somewhere different.
Put a tape across the worst patch
Ten square feet is the line Labor Law section 930 draws between housekeeping and a licensed project. Measuring costs nothing and changes everything after it.
The assessor sets the calendar
Eight assessment licenses in the city against nineteen for removal. The independent half is the constraint, so it is booked first.

What Yonkers owners and tenants ask before booking an inspection
Can the company that finds it also take it out?
Not above ten square feet. Labor Law section 936 bars one licensee from doing both halves at a single property, and bars anyone from holding an interest in both firms there. Two contracts is not an upsell in New York, it is the only lawful shape the job has.
Do I need an air test first?
Usually not. New York State Department of Health publication 7287 says mold testing is not recommended, that no state or federal standard exists for mold in homes, and that sampling can cost more than fixing the water. Sampling earns its place only where the result would change a decision.
Tell us what the tape said
That one measurement decides whether this is a licensed project at all.
