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 Hampshire (NH), commercial real estate is governed by a combination of state statutes and federal law. Commercial properties, including office spaces, retail stores, warehouses, industrial buildings, hospitals, hotels, restaurants, shopping malls, and multifamily rental properties like apartment complexes, are used for business purposes and are subject to specific regulations regarding zoning, land use, and environmental compliance. Leasing of commercial real estate in NH must adhere to the state's landlord-tenant laws, which outline the rights and responsibilities of both landlords and tenants. Additionally, transactions involving commercial real estate must comply with state property laws and may involve considerations such as property taxes, transfer taxes, and recording fees. Investment in commercial real estate, whether by individuals, REITs, or other large investors, is regulated under federal and state securities laws, especially if the investment is structured as a security offering. It's important for parties involved in commercial real estate transactions or management to consult with an attorney to ensure compliance with all applicable laws and regulations.
