Full Breakdown
6. 2 sets the baseline distance at 25 feet from any combustible structure unless the fire is contained in an approved permanent fireplace built to California Building Code clearance standards, with the fire inside a firebox that has an attached chimney and an installed, maintained spark-arresting opening. The code makes two exceptions for portable, spark-arrested equipment: a portable fireplace or fire pit/ring fitted with a working spark arrester needs only 3 feet of clearance from combustible construction at single-family and duplex (R-3) properties, or 15 feet at other residential occupancies such as apartments and condominiums.
6. 6 applies specifically to fire pits, fire rings and fireplaces; portable cooking devices used solely for cooking are carved out under a separate exception in that same section and are not subject to these clearance rules at all.
Violations & Fines
Building or operating a wood-burning fire pit, fire ring or outdoor fireplace that does not meet the required clearance, or that lacks a functioning spark arrester, is a Fire Code violation prosecutable as a misdemeanor under Section 113.4 and Municipal Code § 1-33, with each day the condition continues counted as a separate offense.
