Commercial real estate is property that is used exclusively for business or commercial purposes such as office space; retail stores; warehouses; industrial space (buildings and manufacturing plants); hospitals; hotels and resorts; restaurants; shopping malls; and strip malls. Multifamily rental properties such as apartment complexes are also classified as commercial real estate.

Most commercial real estate is leased to tenants engaged in business or commercial activities. Commercial real estate is often an investment asset for real estate investment trusts (REITs) and large other investors.

In New York, commercial real estate encompasses properties used for business or commercial activities, including office spaces, retail stores, warehouses, industrial buildings, hospitals, hotels, restaurants, and shopping centers. Apartment complexes, despite being residential in nature, are also considered commercial real estate due to their income-generating purpose. Leasing commercial properties is common, with tenants using the spaces for various commercial operations. The regulation of commercial real estate in New York involves a combination of state statutes and local ordinances that govern land use, zoning, leasing agreements, property sales, and building codes. Additionally, commercial real estate transactions and management are subject to federal laws, such as the Americans with Disabilities Act (ADA) for accessibility, and environmental regulations. Investors, including Real Estate Investment Trusts (REITs), often hold commercial real estate as part of their investment portfolios. It's important for parties involved in commercial real estate to consult with an attorney to navigate the complex legal landscape, ensure compliance with all applicable laws, and protect their investment interests.
