Summary
Modesto's Fire Code amendment to the LP-gas permit rule exempts residential barbecue propane containers from a permit only if they hold no more than 5 gallons of water capacity and are used and stored outside of buildings. Larger residential tanks fall under the City's general LP-gas permit and installation rules instead.
Permit(s) shall be required as set forth in Sections 105.5 and 105.6. EXCEPTION: 1. Residential occupancies. Containers shall not exceed five (5) gallons water capacity used for "barbecue" cooking, when used and stored outside of buildings. 2. Approved containers not exceeding sixteen and four-tenths (16.4) ounces when displayed for sale in mercantile occupancies. 3. Factory installed containers for recreational vehicles not exceeding ten (10) gallon water capacity. 4. Factory installed tanks that are permanently attached to recreational vehicles. Distributors shall not fill an LP-gas container for which a permit is required unless the Fire Code Official has issued a permit for installation at the location.

Full Breakdown
6, but it carves out four exceptions so ordinary households and small businesses do not need a permit for common LP-gas uses. The residential barbecue exception is capped at containers not exceeding 5 gallons water capacity, and only when the container is used and stored outside of buildings, not in a garage or enclosed patio. 4 ounces, and two more exceptions cover recreational vehicle propane: factory-installed containers up to 10 gallons water capacity, and factory-installed tanks permanently attached to the RV. Any container that exceeds these thresholds needs a permit before it can be filled: the section specifically bars distributors from filling an LP-gas container that requires a permit unless the Fire Code Official has already issued a permit for that installation at that location.
233, which separately bars LP-gas installations in residential zones outright regardless of water capacity, so the 5-gallon barbecue exception is the narrow carve-out that keeps ordinary gas grills legal on a Modesto patio.
Violations & Fines
A resident or business keeping an oversized or unpermitted LP-gas container, or a distributor filling one without a Fire Code Official permit, is subject to enforcement by the Fire Prevention Division. Because Chapter 3-1 is adopted into the Municipal Code, a violation defaults to the citywide penalty in Section 1-2.01: a misdemeanor with a fine up to $1,000 and up to a year in county jail, or an infraction up to $500 at the City Attorney's election, with each day counted separately.
