Summary
A backyard tool or storage shed in Compton can skip a building permit only if it's a single story, no bigger than 120 square feet, and no taller than 12 feet. Anything larger needs a full building permit application through the Building and Safety Department, under Municipal Code § 15-4.2.
One-story detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area does not exceed 120 square feet (11 m2) and maximum height of 12 feet.

Full Breakdown
2(a)(1) as locally amended and adopted by Ordinance No. 2339 on October 26, 2021: one-story detached accessory structures used as tool and storage sheds, playhouses, and similar uses are exempt from a building permit only while floor area stays at 120 square feet or less and height stays at 12 feet or less. Exceeding either dimension removes the exemption entirely, and the shed must go through the normal building permit process, including plan review and inspections against the 2019 California Building Code's structural and fire standards.
The same subsection carries related accessory exemptions for context: masonry fences under five feet or wood and similar fences under six feet also skip permits, retaining walls up to four feet are exempt unless holding back a surcharge or hazardous liquids, and playground swings and equipment up to eight feet are exempt for one- and two-family homes. 2 states the exemption 'shall not be deemed to grant authorization for any work to be done in any manner in violation' of the Building Code or other city ordinances, so a permit-exempt shed still has to meet setback, zoning, and lot-coverage rules found elsewhere in the code.
In practice, a shed measured at 121 square feet or 12 feet 1 inch tall no longer qualifies and requires full plan check and permit issuance from the Building and Safety Department before construction can begin.
Violations & Fines
Building a shed larger than 120 square feet or taller than 12 feet without first obtaining a building permit is treated as unpermitted construction, enforceable the same as any other Building Code violation. Section 105.2 makes clear the size-based exemption never authorizes work that otherwise violates the Building Code or the City's other ordinances, including zoning and setback requirements.
