Ridgefield, CT Business Licensing & Operations: Auto Repair on Residential Property (2026)

Section 6.2 establishes the Public Water Supply Protection Zone as an overlay adopted to protect the Titicus Valley, Upper Titicus, Sugar Hollow and other identified stratified-drift aquifers that supply the town's drinking water. Subsection 6.2.E, Special Permit Activities, lists the uses the Commission may allow inside the overlay despite the contamination risk, subject to the granting of a Special Permit by the Commission when in compliance with the Regulations and other local, state and federal requirements. Item 8 of that list targets home-based work specifically: home occupations where activities may contaminate ground water quality, and its subitem b names repair and/or maintenance of vehicles, engines or equipment as one of the triggering activities, alongside hazardous-materials handling above 2.5 gallons per container or 55 gallons total on-site (8.a), non-residential fuel storage (8.c) and wastewater disposal from the activity (8.d).

Outside the overlay, a home-based automotive business would instead be evaluated under the ordinary Home-Based Business standards in Section 3.3, but within the mapped aquifer zone the vehicle-repair activity cannot rely on that by-right or Zoning-Permit path at all: it needs Commission-level Special Permit review, the same tier required for gasoline stations, auto repair and service stations, and used-car dealerships under 6.2.E.1. The Commission can also require a stormwater management and drainage plan and an operations plan from a Connecticut-licensed professional engineer under 6.2.G before approving the permit, and may order an Environmental Impact Assessment under 6.2.G.3 for larger applications.
