What Our Clients Say

REVIEW US ON

We hired Harris & Sons to remodel part of our house and also build an addition. The project involved 3 bedrooms, 2 walk-in closets, and 2 bathrooms. Throughout the construction process, which had a few unforeseen complications, Harris & Sons worked to meet our expectations, gave us constructive options, and pushed to keep as close to the schedule as possible. They worked with us on controlling overall cost and understood and respected our financial capabilities and limits. In the end they gave us a beautiful and good quality home.

From our first meeting, Christian Harris stood out. Not only is he incredibly knowledgeable about construction and design, but he also brought a level of calm confidence that made us feel like our home was in the best possible hands. He took the time to understand our vision, walked us through every step of the process, and communicated consistently, something that’s rare in the construction world these days.

I met with Christian and a tall young man whose name escapes me, and was very impressed by their professionalism. They gave me a quote for remodeling after major water damage. Sadly I couldn't use them as I was fighting with my insurance company at the time!! I still think about the awesome job I KNOW they would've done for me and am still upset it never happened.

We had Brian and his team Marcos & Jackson put in a privacy fence for us. The work done was outstanding and the fence looks great. I’m overjoyed by the job they did dealing with the ‘less-than-friendly” rock pile we live on. The work was done efficiently, clean, and fast. I don’t think I heard one curse-word uttered. These guys are clean, professional, quick, and darn good at what they do! I couldn’t recommend them more and we’ll be calling them again to put in our deck! Thx guys!!!

This team did such an amazing job building my pergola cover and enclosing my deck. Very professional and quality work. All of their suggestions for design were great, and I would recommend them for any project.

We have worked with Christian and his team for numerous projects around our home for the past year. They built and stained a beautiful fence for us, and also built a paver patio and pathway in our backyard. They are consistently friendly, communicative, and deliver high-quality work. Their employees are considerate and helpful. They have excellent follow-through from start to finish, and are exceptionally priced. We would highly recommend this team and we will continue to utilize their skills around our home going forward.

Tenant Improvements for Commercial Spaces

What Are Tenant Improvements?

Tenant Improvements (TIs), also known as leasehold improvements, refer to any changes made to a commercial rental space to customize it for the specific needs of the tenant. These can include layout changes, flooring, lighting, HVAC modifications, wall partitions, painting, or even complete interior rebuilds.

At Harris & Sons, we work closely with both landlords and tenants to design and execute renovations that enhance the value of the space and improve usability, branding, and compliance.

Frequently Asked Questions

1. What are tenant improvements (TIs)?

Tenant improvements refer to custom renovations or modifications made to a commercial space by the tenant or landlord to better suit a tenant’s business needs. This can include building out office spaces, upgrading restrooms, adding partition walls, new flooring, lighting, HVAC systems, and more.

2. Who pays for tenant improvements – the landlord or the tenant?

It depends on the lease agreement. In many cases, landlords offer a Tenant Improvement Allowance (TIA) to cover or offset renovation costs. At Harris & Sons, we work with both landlords and tenants to stay within budget while maximizing value.

3. How long does a tenant improvement project take?

The timeline depends on the scope of work. Simple upgrades may take a few weeks, while full-scale commercial buildouts can take several months. After reviewing your plans and space, we provide a detailed timeline and schedule.

4. Do you help with permits and code compliance?

Yes. We handle all required permits and ensure that all work complies with local building codes, ADA regulations, and commercial zoning laws in New York and New Jersey. Our team stays up-to-date on all regulatory requirements.
