California Fourplexes and Quadplexes For Sale

A fourplex, also called a quadplex, is a single four unit apartment building with four separate living units. Each unit usually has its own entrance, kitchen, and bathroom, arranged side-by-side or stacked within one structure. These properties offer investors multiple income streams and the flexibility to live in one unit while renting out the others—making them a practical step into multifamily real estate investing.

How do state regulations affect fourplex and quadplex ownership?

Each state has its own landlord-tenant laws, building codes, and permitting standards. These can influence lease terms, security deposits, notice periods, and renovation requirements. Before investing, review your state's housing regulations and speak with a real estate attorney or broker who specializes in multifamily properties

Are there state-level tax benefits or programs for multifamily owners?

Some states offer property tax abatements, renovation incentives, or energy-efficiency grants for multifamily upgrades. These programs change frequently, so check with your state's housing or economic development agency for current eligibility guidelines.

What types of insurance should I carry for a fourplex or quadplex?

Investors should consider comprehensive coverage that includes property, liability, and loss-of-rent protection. Depending on the state, you may also need flood, windstorm, or earthquake insurance. Before finalizing coverage, review potential commercial property risk factors with an insurance professional familiar with multifamily portfolios.

Should I invest in an existing property or a new development?

An existing fourplex or quadplex may provide immediate cash flow and established tenants. New construction can offer modern features, fewer short-term repairs, and stronger depreciation benefits. The right option depends on your risk tolerance, timeline, and ability to manage development or renovation costs.
