Your leased space, built out and ready to use

A tenant improvement in Newark, NJ turns a leased commercial space into one a tenant can actually use, from new walls, ceilings, and flooring to electrical, HVAC, plumbing, and finishes, anywhere from a quick refresh to a full white-box fit-out. Most landlords and business owners worry about the same three things. Here is how we take each one off your plate.

  • Your business keeps running

    We phase the work around your hours and seal off the dust, so you stay open and operating while we build.

  • On time, as promised

    A realistic schedule in writing before we start, so your move-in or opening date holds and the space is ready when you need it.

  • No hidden costs

    The full price up front with no surprise change orders, plus financing to help you build out sooner.

Our licensed team handles every part of the build-out, from the first walkthrough to the final code-ready handoff.

"Had a really great experience with Ultimate Contractors Corporation on a new construction project. Everything went super smooth from start to finish, and the quality of the work came out even better than I expected. Jeff and the team are awesome to work with. They know what they're doing, stay on top of everything, and actually care about doing a good job. Communication was easy, they showed up when they said they would, and handled everything the right way. It's hard to find a solid, trustworthy crew, but these guys are the real deal. Definitely recommend them if you want the job done right."

"After having a sudden water leak and having the whole house fall apart, I found the UCC team and Jeff was very professional from the very beginning. He was very attentive to everything that needs to be done and most importantly he understood my urgency and started working right away. Words can't even explain how grateful I am for the amazing work Yico and Patricio did. I am so happy with the UCC team and their work."
Ismot Tuba
"I cannot recommend them enought. I am a busy person with a family and I had a severe unexpected plumbing issue with my bathroom. I am not a handyman by any means. I started calling companies and they either stopped replying or wanted my to charge me crazy amounts. I was frustrated. I friend recommended me to this place and I am very thankful. They helped me right away and explained me all I needed to know about the price I was been charge. Specifically that guy tommy. He is a man of a few words. However, was really nice and professional. REALLY RECOMMEND THIS PLACE"
Holger Damian Velez Garcia

Tenant improvements questions, answered

How much do tenant improvements in Newark, NJ cost?
Tenant improvement cost depends on the size of the space, the condition you start from, and how much you need to change, like walls, electrical, HVAC, plumbing, and finishes. Because every space and lease is different, we give you clear, transparent pricing in writing after a free walkthrough, with no hidden fees. Call (908) 344-2984 to get started.
How long does a tenant improvement project take?
Most tenant improvement projects run about 3 to 8 weeks once we start on site. A light refresh finishes faster, while a full fit-out with new walls, electrical, and HVAC takes longer. We give you a realistic timeline before any work begins so you can plan your move-in or opening date.
Do you handle the permits and inspections for tenant improvements?
Yes, we handle the permits. As a licensed New Jersey general contractor, we pull the building, electrical, plumbing, and mechanical permits your tenant improvement needs and we manage the inspections, so you and your tenant do not have to deal with the town or the paperwork.
Can you work around an open business or other tenants?
Yes, we work around your operations. We schedule the loud or disruptive work for off hours when we can, keep the job site clean and safe, and stage the build so a running business or neighboring tenants stay open. We plan the sequence with you before we start.

Yes. Ultimate Contractors Corporation is a licensed, insured, and bonded general contractor in Newark, NJ, holding NJ Home Improvement Contractor license #13VH12312800. You get a credentialed team and clear paperwork on every tenant improvement project.
