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 California, 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. California law regulates commercial real estate transactions through various statutes that govern the sale, lease, and financing of such properties. The California Civil Code provides specific provisions for commercial leases, addressing issues such as lease terms, security deposits, and the rights and obligations of landlords and tenants. Additionally, local ordinances may also impact commercial real estate, including zoning laws that dictate land use and building codes that ensure safety and compliance. Commercial real estate is a key investment vehicle, often held by REITs and other large investors. It's important for parties involved in commercial real estate transactions to consult with an attorney to navigate the complex legal landscape, ensure compliance with state and federal laws, and protect their investment interests.
