California Pool Regulations: What You Need to Know
No matter where you live or what type of pool you plan to own, ensuring compliance with state and local regulations is essential throughout the design and construction process. The California Department of Health provides detailed information on swimming pool laws and requirements.
Keep in mind that pool maintenance and safety regulations often change. While these California guidelines are a helpful starting point, always check local laws to ensure compliance with the latest standards.
Before diving into the specifics of California pool ownership, here are five key regulations to consider when planning your residential swimming pool.
• What’s the maximum depth for a residential pool?
Most cities in California have enacted codes that prohibit residential pools from being deeper than eight feet. However, it’s important to check with your city to make sure that a different rule doesn’t apply where you live which is also a good rule to follow for any zoning or permitting issue.
• How far does a pool have to be from a building or property line in California?
For safety purposes, it’s vital to make sure there’s adequate distance between the edge of your pool and the outer wall of your home (which will also make it easier to enjoy your outdoor space). This distance, which is called the “setback,” is usually at least 10 feet but can vary from city to city. In Sacramento, for example,“In no case shall a swimming pool be located within three-feet of a property line, building, or other structure.” By contrast, Torrance, a city within the Los Angeles metropolitan area, requires that “in no case shall the outer walls of a pool be less than five (5) feet from an interior side property line or rear property line or building or be less than ten (10) feet from any side.”
• Are fences required around pools?
Safety fences (also referred to as “enclosures” in some municipal codes) may be required in certain locations in California. For example, under Sacramento’s regulations, pools must feature at least two drowning prevention safety features from a list of seven, with one option being to “isolate” the pool from access by using a fence. Another option is to set up “a gate that is self-closing and self-latching and can accommodate a key lockable device.”
• Are pool covers required?
A pool cover is not strictly required in every location. However, you may be required to include drowning prevention features in or around your pool, like Sacramento’s requirement to choose two safety features from a list of seven possible options. One of these options is to use a safety cover more specifically, “The pool shall be equipped with an approved safety pool cover that meets all requirements of the ASTM Specifications F1346-91.” These types of regulations also exist in other major cities, like Los Angeles, whose detailed pool cover regulations can be viewed here.
• Are there any water regulations?
In recent years, California has been impacted by droughts and severe weather, including wildfires. You can learn about how this might impact your water usage by visiting the State Water Resources Control Board website to read about emergency regulations or, for L.A. residents, the Los Angeles Department of Water & Power, which has shared FAQs about water restrictions. Fortunately, most pool owners in California have not been significantly impacted by drought-related restrictions.
Local regulations can differ even by neighborhood, so it’s smart to work with an experienced San Juan Pools builder who will handle zoning, permitting, and compliance for you—from start to finish.
Seasonality
California’s diverse geography from coastal towns and desert valleys to mountain communities means pool ownership varies by region. While much of the state enjoys warm weather year-round, seasonality still plays a role. Cooler winter months may call for a pool heater or an automatic cover to retain warmth, while summer drought conditions can influence water use and maintenance routines.
That variation also extends to design preferences. Whether you're in a minimalist modern home in Palm Springs or a lush backyard in the Bay Area, Californians tend to seek pools that match their unique style. Fiberglass pools come in a wide range of shapes and finishes, offering flexibility to complement the state’s eclectic aesthetic.
Timing is another key consideration. Fall and winter are often the best seasons to build a pool in California, giving you a head start before summer hits. And because fiberglass pools are pre-manufactured off-site, installation can be quicker and more efficient helping you get from backyard project to poolside lounging with fewer delays.
