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 Massachusetts, commercial real estate encompasses properties used for business or commercial activities, including office spaces, retail stores, warehouses, industrial buildings, hospitals, hotels, restaurants, shopping centers, and multifamily rental properties like apartment complexes. These properties are typically leased to tenants for business purposes. The leasing, sale, and management of commercial real estate in Massachusetts are governed by a combination of state statutes and common law. This includes regulations on zoning, environmental compliance, building codes, and landlord-tenant relationships. Commercial leases are subject to negotiation and must adhere to contract law principles. Additionally, Massachusetts law requires certain disclosures and adherence to anti-discrimination statutes. Real estate investment trusts (REITs) and other large investors often hold commercial real estate as part of their investment portfolios. These entities must comply with both state and federal securities laws if their interests are publicly traded. The regulation of REITs also involves compliance with the Internal Revenue Code for tax purposes.
