Are Tiny Homes And Houses Legal In California?

    Are Tiny Homes Legal In California?

    Although tiny homes are generally legal in California, there are certain areas where they are not permitted as permanent residences. It is essential to familiarize yourself with the zoning and building codes of your city. If you plan to live in a tiny house, you must determine if California allows them in your location.

    For instance, let’s examine San Francisco‘s zoning laws. These regulations prohibit houses where rooms are smaller than 70 square feet. However, just an hour away in Isleton, you will find Northern California’s first legal tiny house community called Park Delta Bay. Therefore, it’s evident that the legality of tiny houses varies significantly.

    California’s Tiny House Laws

    In 2016, a bulletin issued by the California Department of Housing and Community Development defined the structures that are considered as tiny homes. This definition encompassed Manufactured Homes, factory-built housing, park trailers, recreational vehicles, and camping cabins.

    Here is a list of what cities and counties in California allow tiny homes:

    • Fresno
    • Los Angeles
    • San Diego
    • San Luis Obispo
    • San Jose
    • Santa Cruz
    • California City

    Notably, Sacramento and San Francisco are among the areas where tiny houses are currently illegal. However, please note that these restrictions are subject to change, so it’s important to stay updated.

    Building Codes And Permits

    If you intend to build a tiny house in California, you will need to obtain a permit from your local planning department. To acquire the permit, you must adhere to the applicable building codes. The California State Building Code (CSBC) encompasses both the California Building Code and the California Residential Code.

    The following building codes are relevant to tiny houses:

    • Ceilings must be at least 7 feet and 6 inches high.
    • There must be at least one room with a gross floor area of 120 square feet or more.
    • The net floor area for all other living spaces must exceed 70 square feet.
    • Basic requirements must be met for plumbing, lighting, ventilation, smoke/carbon monoxide detectors, and emergency exits.

    The minimum size of your home will depend on its occupancy. The rules differ for various types of tiny homes. However, accessory dwelling units (ADUs) must have a living room with more than 220 square feet of floor space, with an additional 100 square feet for each additional occupant beyond two. Additionally, ADUs must include the following:

    • Cooking appliances
    • A kitchen sink
    • A separate closet
    • Provision for refrigeration

    Tiny Homes And Zoning Regulations

    Zoning regulations apply to every lot in California. If you plan to build a tiny home on vacant land, it is important to ensure you are familiar with the applicable zoning regulations. Depending on the circumstances and county laws, it may be possible to apply for zoning variances or exemptions before constructing your tiny house in California.

    However, it is essential to keep in mind that there is no guarantee of success in obtaining these variances or exemptions. Additionally, the cost of legal advice, as well as the associated paperwork, can quickly accumulate. Before making an appeal, it is advisable to inquire with your local planning department regarding the relevant codes.

    The optimal approach is to acquire land that is already suitable for your plans, as this can help streamline the process and avoid potential complications. With complex zoning regulations in place, it may be more prudent to seek a more standard type of housing, and we can help with this.
