We're the #1 Pool Safety Barrier Provider in the U.S.
With the rise in residential pool installations across the state, California pool fence law has become stricter to help prevent avoidable tragedies. If you’re building a new pool or remodeling an existing one in 2025, it’s crucial to stay compliant with updated safety regulations.
The California Pool Safety Act, enacted under Senate Bill SB442, establishes minimum safety standards for residential swimming pools and spas. This law mandates that all new or remodeled in-ground pools in California must have a physical barrier and at least two of the 7 drowning prevention safety features.
According to the CDC, drowning is the leading cause of unintentional injury-related death among children ages 1 to 4. In California alone, dozens of these incidents occur annually in residential pool environments, often when a child is left unsupervised.
Layered safety measures- fences, alarms, and covers significantly reduce drowning risks. Prior to SB442, many incidents involved pools that lacked proper barriers or had outdated safety systems. By strengthening the California pool fence code, lawmakers aimed to ensure that every pool includes multiple fail-safe protections.
Under the California pool fence law, the minimum required height for a pool barrier is 60 inches (5 feet), measured from the exterior side facing away from the pool. This standard is not coincidental.
By setting the minimum height at five feet, the law aims to reduce unintentional drownings, which remain a leading cause of death among young children in California.
To remain compliant:
These specifications are designed to ensure a truly secure perimeter around your pool.
The pool gate requirements in California are strict for good reason. Gates must:
These measures prevent unsupervised access and reduce the risk of gates being accidentally left open.
In addition to a compliant fence, California pool fence law require at least two of the following safety features:
Removable mesh fences are a popular and legal solution. To comply:
At PoolGuard™, we specialize in premium-grade mesh pool fences that are fully compliant with ASTM F2286. Our removable mesh systems are engineered for safety, aesthetics, and code compliance – making them a top choice for California homeowners.
Under the California Pool Safety Act, approved safety covers are one of the permitted secondary safety features, and for good reason. Whether manual or automatic, these covers must meet rigorous standards that ensure they can support weight, resist tampering, and fully prevent access when closed.
Even if a gate is accidentally left open or a child manages to bypass a fence, a properly secured pool cover provides an additional layer of defense that can stop a potential tragedy before it happens.
For compliance, pool covers must adhere to ASTM F1346-23 standards, which verify their ability to block access and withstand environmental exposure.
Under ASTM F2208, approved pool alarms are tested for sensitivity, durability, and effectiveness in real-world scenarios.
Exit alarms are required on any door or window that opens directly into the pool area. These alarms emit a loud, unmistakable sound when opened – helping prevent unnoticed entry, especially by children or guests. To comply with pool fence law in California, these alarms must:
While the pool safety requirements in California set the statewide minimum requirements, many cities and counties enforce stricter regulations, especially in densely populated or high-risk areas. If you’re installing or upgrading a pool fence in California, it’s critical to review your local codes to ensure full compliance.

When a building permit is issued for the construction or remodeling of a pool or spa at a private single-family home, the pool or spa must be equipped with at least two of the following seven drowning prevention safety features:
If your pool doesn’t comply with the CA pool fence law, you may face legal penalties, fines, and delays in home inspections or permits. Non-compliant pool areas are considered a serious safety hazard, especially for children. If an accident occurs, the homeowner can be held liable for injuries or fatalities, and insurance claims may be denied.
