In-house Services
​​​Since 1969, Hartz has created an extensive portfolio of mixed-use developments, premier office buildings, state-of-art industrial facilities, leading hotels and prime residential projects. Today, we own and operate more than 250 properties totaling more than 38 million square feet and we continue to seek opportunities to expand our holdings. The in-house departments detailed below give us the capability to provide unparalleled service to our tenants and to efficiently operate our portfolio.​
Today, Hartz Mountain hosts one of the most comprehensive in-house construction and architecture departments, capable of designing and building a wide range of projects, including commercial office buildings, retail centers, hotels, residential properties, research and development laboratories, and industrial properties. Time and time again, the Hartz team has met the needs of the most demanding clients, whether it be complete site engineering, highly specialized tenant build-outs or complete turn-key building projects.

Despite their distinct appearance, every property has something in common. Quality. Efficiency. Safety. These are the watchwords of the Hartz Construction Services team.
Perhaps that's why Hartz Mountain continues to serve, and satisfy, a stellar roster of clients throughout the Northern New Jersey/New York region. It is our goal to consistently deliver timely, cost effective, and high-quality projects.
We measure our success not only by the outstanding projects we have completed, but by the high percentage of clients who return to us for their construction needs.

​The energy and enthusiasm that underscore the Hartz Property & Asset Management team comes from dedicated professionals who are the most knowledgeable in the industry on property and asset management. Daily, these professionals successfully manage and maintain more than 240 properties and more than 38 million square feet of office, retail, and industrial space. One Executive directs the Property Management team and it is supported by a Vice President of New York properties, a manager of field operations, and property managers. Building portfolios are generally grouped by the type of property or by their geographic location, and property managers are assigned as such.

Their responsibilities range from building operations and systems to roads and grounds, including repairs, maintenance and capital improvements, as well as fire and life safety; security; and appearance and cleanliness of the properties. In addition, the team provides tenant services; lease administration; risk management, and compliance with federal and state laws and regulations.

Items that fall within this area include security, janitorial, cafeteria, landscaping, and maintenance. They include roofing, waterproofing, and parking deck renovations as well as central purchasing of supplies, fleet maintenance and general operational issues. These are traditional property management services. But Hartz Mountain also provides an innovative service in asset management. For example, our team's expertise often includes retrofitting and upgrading properties that require enhancements. The upgrades may improve the look of the building, but more frequently also increase its value. This not only pleases tenants, but also improves the building's marketability to new occupants. In addition, the Hartz Property Management group can get involved at the onset-in the planning stage of a project to ensure that its construction and design are optimal.

Our goal is to control costs, enhance value, and protect the assets for the long term. That is one reason we directly manage the property. That way, we can ensure quality control-that our high standards are being met and exceeded. In addition, we leverage the buying power inherent in our portfolio to operate our buildings. Hartz buildings boast the most competitive operating costs in the State of New Jersey while still being able to deliver first class operations.

We've built an excellent reputation for responsiveness in service, too. It has helped us forge lasting relationships with a broad range of corporate tenants. Based on our strength in retaining existing tenants and attracting new ones, Hartz has an enviable record in maintaining properties consistently at full occupancy levels.

This is exemplified in an achievement, the 2000 National Commercial Real Estate Customer Service Award for Excellence. Hartz Mountain Industries won the Best in the Industry ranking-truly an achievement that reflects our dedication and commitment to the highest level of quality in asset and property management.

With our strong in-house legal team, Hartz has successfully obtained approvals and permits for many high profile, large-scale and complex projects such as our Harmon Meadow and Harmon Cove developments in Secaucus, New Jersey and many others.
