Morris County · Route 46 & Local Services
Mountain Lakes Business & Shopping
Mountain Lakes is primarily residential, so its business community is concentrated rather than sprawling. Route 46 carries most of the borough's medical, professional, automotive and office activity, while a smaller number of long-established service businesses operate on local streets.
This directory focuses on businesses physically located in Mountain Lakes Borough. Restaurants are maintained separately on the Food & Drink page.
Mountain Lakes business areas
The borough has no conventional downtown shopping district. Most commercial activity is concentrated in a few office and business areas.
A compact medical and child-care cluster that includes early education and walk-in/family medical services.

Automotive, real estate, plumbing and other businesses extend along the borough's highway edge toward Denville and Parsippany.
Medical offices, professional services and mixed-use properties form a smaller nonresidential cluster closer to the residential center of town.
The YMCA and long-running automotive, energy and home-service businesses add to the borough's local service economy away from Route 46.
Municipality matters more than the mailing city.Route 46 changes municipal boundaries quickly between Mountain Lakes, Denville and Parsippany-Troy Hills. NJTGO includes a business here only when its location is in Mountain Lakes Borough, not simply because a directory uses the 07046 ZIP code or “Mountain Lakes” as a mailing address.
