Commercial Questions
What is a change of use?
Before you can open, the town, city or village usually needs to approve how the space will be used. When a space changes from one kind of business to another, such as office to retail, or retail to a fitness studio, that's typically a change of use. It comes with its own review.
What kinds of commercial spaces do you handle?
Tenant changes and fit-outs for retail, fitness, medical, office, restaurant and assembly spaces. We work for business owners, landlords and tenants.
What if the new use isn't allowed by zoning?
We review the records first. If the use isn't allowed as-of-right and needs a variance or a zoning hearing, we'll flag it early. We can refer you to a zoning/land-use attorney before you sink money into a build-out.
The last tenant left violations. Are they my problem?
They often need to be cured before you can move forward. We review what was cited, line up the plans and permits to cure it, and handle the filing and inspections.
Can you help with a sign permit?
Yes. We file sign permits for businesses and close out old ones.
Can you close open commercial permits?
Yes. We close open commercial permits that need to be cleared before a sale, lease or refinance. See Open Permit Close-Outs.
Do you handle commercial work in the villages too?
Yes. We work with every building department in Nassau County, including village departments like the Village of Hempstead.
Do you work outside Nassau County?
No. We serve Nassau County only, not Suffolk County or New York City.
