Engineering Department

Michael Disko, Engineer

The Engineering Department both assists and protects the public by means of guidance and inspection to see that Borough standards for site work are adhered to, thus ensuring the health, safety and welfare of the general public. The Department will intercede on behalf of the citizens when drainage, roadway or general site work conditions become a matter of public concern and routinely inspects all construction projects in the Borough. The goal of the Engineering review and inspection is to ensure that drainage problems are not created for the homeowner or his neighbors. Generally projects which disturb more than 5,000 sq. ft., add more than 50% to an existing structure, or projects which have significant re-grading, such as driveways which are being curbed, will require professionally engineered plans.

Zoning Requirements

Residential Uses

The rental or resale of residential dwellings requires a Certificate of Continued Occupancy (CCO) which includes the smoke detector inspection.  The fee is $100 and the application is available in the Zoning Department located on the second floor of the Borough Hall. Accessory structures such as sheds, pools, and gazebos require certain setbacks from property lines and may also require a building permit. Call the Zoning Department for information. The Borough of Mountainside's property maintenance ordinance requires: 1) The exterior of dwellings be maintained and painted; 2) Premises be kept free from debris, overgrown grass and weeds, the storage of old parked vehicles, and parts and abandoned appliances. The parking of recreational vehicles and commercial vehicles is prohibited unless in an enclosed garage or shielded from view. 

Commercial Uses

A Certificate of Occupancy is required prior to the occupancy and commencement of new businesses, office tenants, warehouses and industrial uses.  The fee is $75, which includes verification from the Office of Fire Prevention that the annual fire inspection is current and without outstanding violations. Applications are available in the Zoning Department.
