1.3 New York Neighbor Notification Law & Visual Posting

1.3 New York Neighbor Notification Law & Visual Posting

Public transparency and bystander exposure protection are core objectives of New York pesticide legislation. To safeguard residents, children, and pets from unintended chemical drift and post-application contact, New York enforces two interrelated regulatory systems: the Neighbor Notification Law (ECL Article 33 Title 10) and the statewide Visual Notification Marker Posting Regulations (6 NYCRR § 325.40).

The County Opt-In Framework (ECL Title 10)

Enacted as Chapter 285 of the Laws of 2000 and effective March 1, 2001, the New York Neighbor Notification Law (ECL § 33-1004 and § 33-1005, implemented at 6 NYCRR § 325.41) is unusual because it is a state statute that takes effect at the local level through a county opt-in mechanism. A county's legislative body (or the New York City Council) must pass a local law adopting the state statute in its entirety. A county cannot modify or weaken the provisions—it is an all-or-nothing adoption.

Major counties across New York that have enacted local neighbor notification laws include Nassau, Suffolk, Westchester, Rockland, Albany, Erie, Monroe, Ulster, and Tompkins, as well as the five boroughs of New York City.

48-Hour Prior Written Notification Requirements

In any county that has opted into the Neighbor Notification Law, commercial pesticide applicators performing outdoor commercial lawn applications must adhere to strict advance notice rules:

Who Must Receive Prior Notice? (One Test, Not Two)

The statutory trigger is a single compound test, and candidates lose points by splitting it into two independent rules. Notice is owed to the occupants of dwellings and occupied structures on property that is both:

1. Abutting the property receiving the application — it shares a boundary line; and
2. Within 150 feet — that abutting property's boundary lies within 150 feet of the application site.

A house 90 feet away across a road that separates the two parcels is not abutting, so no notice is owed. A house on a directly adjoining parcel whose boundary is 400 feet from the treated area is abutting but outside 150 feet, so again no notice is owed. Both conditions must be true at once.

Multiple dwellings (apartment buildings, condominiums, and similar occupied structures) are handled through the building owner or agent: the applicator delivers or mails written notice to the owner/agent, who is then responsible for notifying tenants and posting in common areas.

Timing and Delivery of Notice

• Provided at least 48 hours in advance: The notice must be given at least 48 hours prior to the commercial lawn application. The regulation allows three delivery methods: mailing it, leaving it with a responsible adult, or leaving it in a conspicuous location on the abutting property. Note what the rule does not say — there is no separate "postmarked five business days ahead" standard. The 48-hour window is the whole test, so when mailing, allow enough transit time that the notice is in the neighbor's hands before it opens.
• Type size: The required information must be printed in at least 12-point type.
• Language: DEC requires notices in English and Spanish, plus any additional language the Commissioner determines is necessary.

Mandatory Written Notice Contents

• The address at which the application is to take place.
• The name and telephone number of the person applying or supervising the application, together with the pesticide business registration number or applicator certification identification number.
• The specific date of each scheduled application, plus two alternate dates in case weather prevents the application on the primary date.
• The product name and EPA Registration Number of each pesticide to be applied.
• The DEC-specified statement advising occupants of potential hazards and of the availability of label information. The regulation prescribes this wording, and the two contacts it names are the National Pesticide Telecommunications Network at 1-800-858-7378 (now operating as the National Pesticide Information Center) and the New York State Department of Health Center for Environmental Health information line at 1-800-458-1158 — not a DEC regional office.

[!NOTE] Title 10 of ECL Article 33 also requires a written contract for commercial lawn applications — listing the application dates, number of applications, product names, applicable warning statements, business and applicator identification, and total cost — and requires the customer to be notified of, or to approve, any alternate date. The contract requirement is statewide; it does not depend on county opt-in.

Visual Notification Marker Specifications (Statewide Mandate)

While 48-hour advance neighbor notification depends on county opt-in status, Visual Notification Posting (6 NYCRR § 325.40) is a MANDATORY STATEWIDE REGULATION applying to every commercial lawn pesticide application in all 62 counties of New York State.

Retail Warning Signs (Opt-In Counties)

ECL § 33-1005 directs the Commissioner to set uniform standards for a consumer pesticide use information sign placed in retail establishments that sell general-use pesticides for commercial or residential lawn application. The statute fixes the sign's content and typography rather than a sheet size:

• Typography: Letters in at least 16-point bold type, printed against a brightly colored background.
• Language: English and Spanish, plus any other language the Commissioner determines is necessary.
• Required content (three elements):
  1. A warning notice directing consumers to follow the directions on the pesticide label.
  2. A statement informing the customer of the posting requirements.
  3. A recommendation that the customer notify neighbors before applying, so neighbors can take precautions to avoid exposure.
• Location: Displayed where the lawn pesticides are offered for sale, so the consumer sees it at the point of purchase.

[!NOTE] Do not memorize a sheet size for this sign. The tested facts are the 16-point bold type, the brightly colored background, the English/Spanish requirement, and the three content elements.

Two Separate Exemption Lists — Know Which One Is Being Asked About

This is the most commonly confused part of the law. There are two distinct lists, and they do different work.

List 1 — Not a "commercial lawn application" at all

If the work falls here, Title 10 never attaches in the first place:

1. Agricultural commodity production — farms, orchards, vineyards, and nurseries growing a commodity.
2. Residential application to your own property — a homeowner treating their own lawn.
3. Applications around or near a building foundation for the purpose of indoor pest control — the classic perimeter barrier treatment done as part of structural work.
4. Applications by, or on behalf of, government agencies — with an important carve-back: agencies must still post visual notification markers where the application is within 100 feet of a dwelling, multiple dwelling, public building, or public park.
5. Golf courses and turf farms.

List 2 — Commercial lawn applications that are exempt from prior notice

These are lawn applications, but the 48-hour neighbor notice is not required:

1. Granular pesticide products — the single most-tested exemption, because granules do not drift the way sprays, dusts, and powders do.
2. Spot applications — small, localized treatments rather than broadcast coverage.
3. Injection of a pesticide directly into a plant or into the ground.
4. Horticultural soaps and oils.
5. Cemetery grounds and turf.
6. Emergency applications.
7. Products meeting EPA standards for minimum-risk, reduced-risk, or biopesticide status.

[!WARNING] Being exempt from the 48-hour prior notice does not automatically exempt an application from the statewide visual marker requirement in 6 NYCRR § 325.40, or from the written-contract and label-information duties in Title 10. Check each obligation separately.
