Direct answer
The short answer for Westport, CT
In Westport, plan meth residue cleanup around the Connecticut Department of Public Health (DPH) target. That target is below, or less than, 0.1 µg/100 cm² of meth. Treat it as a state guideline, not a town law. Saugatuck River apartments, summer leases near Compo, and homes of artists still need wipe tests. They also need choices about wall heat-and-cool units (PTACs). Keep a file on whether meth was made or only used before the next summer booking.

Local planning context
Along the Saugatuck River and near Compo Beach, you find walk-up rentals, artist live/work spaces, and inland colonials. Many are home to creative workers and commuters. Residue often turns up in January, when summer cottages turn over. It may also show up after a tenant leaves smoking debris in a riverfront studio. Or a buyer may ask for wipe tests before a June closing. The Connecticut DPH Guidelines for the Cleanup of Connecticut Methamphetamine Labs list the cleanup target used in the state. That target is below, or less than, 0.1 µg/100 cm² of meth. The guidelines also say no state law requires lab cleanup in ordinary homes. Licensed facilities are different. So is a case where the commissioner finds a public health threat. Cite the state target. Do not make up a microgram rule from a beach committee.
Connecticut DEEP hazardous waste rules may apply when chemically tainted materials leave a riverside rental. Signs of cooking in a garage studio widen the waste review. Those signs include solvents and stained utility sinks. Smoking alone can still coat beach linens, loft furniture, and PTAC coils after months of winter closure. Sand tracked inside can mix with torn-out dust if bags are not sealed. River humidity and salt air slow drying after wet washing. That affects when you can test before the busy booking season.
Art events and summer leases push owners to reopen fast. But a fading smell after a closed-up winter is not a lab result that meets the CT DPH target. Keep test maps and chain-of-custody forms in the rental binder. Chain-of-custody means a signed trail naming every person who held a Westport sample. Also be clear in the binder about what is a guideline and what is an order. Under state guidelines, ozone machines and fresh paint do not meet the below, or less than, 0.1 µg/100 cm² target.
