Ontario FAQ
Can I have a small bonfire with friends in Ontario?
Only if the fire is inside an approved pit or portable fireplace burning clean wood, stays 25 feet from structures, and is attended by a sober adult with water nearby.
What about a propane fire table on a patio?
Listed propane appliances are allowed and can sit much closer to structures per the manufacturer instructions, and they are not suspended by SCAQMD no-burn days.
Rialto FAQ
Can I have a backyard fire pit in unincorporated San Bernardino County?
Yes, with California Fire Code 307 compliance: 15 feet from structures (3 feet for small devices under 1 cu ft fuel area), clean dry wood only, attended at all times, water/extinguisher present, and never during a Red Flag warning or in designated fire restriction zones.
Are propane fire pits treated differently?
Yes. Propane and natural gas fire pits are generally allowed without a permit and have lower clearance requirements because they have no embers or sparks. They are often permitted during periods when wood burns are suspended, though local fire district rules in high-hazard zones can vary.
