NEW JERSEY FIRE CODE FAQ
What Kind of Properties Does It Apply To?
This new rule applies to all rental properties but does not apply to homes that are owner-occupied and used solely as single-family or two-family residences (like townhouses or attached homes where the owner lives full-time).
What’s Not Allowed Anymore?
You can no longer use wood-based or other combustible mulch:
- Within 18 inches of any building or structure
- Within 18 inches of a deck, porch, balcony, or anything made of combustible material
- Within 18 inches of any designated smoking area (as defined in NJ’s Fire Code)
What Is Allowed?
There are a few exceptions to this rule:
- Live plants (like shrubs, flowers, and trees) are okay as long as they’re not within 18 inches of a building, or under a wooden overhang that’s less than six feet off the ground.
- Buildings with non-combustible exteriors (like concrete or brick with no wood components)
- Fire-resistant mulch (be sure it’s clearly labeled as such)
Even though this rule specifically targets rental properties, every property owner should take it seriously.
How much time do I have to comply?
This revised code states that its provisions will become operative (and, thus, enforceable) twelve months after the effective date of the new rules, which is April 15, 2026. So, while you have a bit of time to prepare, it’s best to begin planning for compliance with this important code update right now.
What is River Stone?
River stone is a smart and safe alternative to traditional wood-based mulch, particularly when fire prevention is a priority. Unlike mulch, which is made from organic, combustible materials like bark or wood chips, river stone is completely non-combustible. This makes it far less likely to ignite, smolder, or contribute to the spread of fire, especially important in areas near buildings, decks, and designated smoking zones. In fact, under hot, dry summer conditions, wood mulch has been known to spontaneously combust or catch fire from something as small as a discarded cigarette. River stone eliminates this risk entirely.
River stone doesn’t break down, fade, or need to be replaced every season the way mulch does, reducing ongoing maintenance and replacement expenses. In addition, it helps with weed suppression and improves drainage without attracting insects or harboring mold, which are common concerns with organic mulch. For property owners, especially those managing rental units or commercial spaces where fire safety codes are tightening, investing in river stone offers long-term peace of mind, curb appeal, and cost efficiency.
