How Pomona Handles Building Safety: A Practical Guide

Pomona maintains 146 local ordinances across all categories, and 4 of those deal specifically with building safety. Here is a breakdown of what the city actually requires, what is prohibited, and where Pomona falls on the strict-to-permissive spectrum compared to other cities.

Building Inspections

Converting a Pomona commercial or industrial building into work/live units runs through a defined permit-and-inspection sequence under City Code Sec. 74-133: a work/live unit permit, a separate building permit for construction, a business license, and a final building-official inspection before a certificate of occupancy issues. No occupancy is allowed until every step is signed off.

Key details: Governing section: City Code Sec. 74-133. Permits required: Work/live unit permit and separate building permit. Drawing requirement: 3 sets, 1/4-inch-to-foot scale. Final step: Final inspection then certificate of occupancy. Cure period: 7 days after non-life-threatening violation notice.

Occupying a work/live unit before the work/live unit permit, building permit, and final certificate of occupancy are all in place is a code violation the building official can order discontinued. Where the violation is not life-threatening, the occupant gets seven days after written notice to comply (Sec. 74-133(e)(3)); uncorrected or life-threatening violations can be pursued as a misdemeanor under the Code's general penalty, Sec. 1-7.

Plumbing Permits

Pomona requires all plumbing installation, alteration and repair work to follow the California Plumbing Code, 2025 Edition, based on the 2024 Uniform Plumbing Code, adopted under City Code Sec. 74-31 alongside the Building, Residential, Mechanical and Electrical Codes. The building and safety division issues permits, and fees are set separately by city council resolution under Government Code Sections 66016 and 66020; state regulations control whenever they conflict with the local amendments.

Key details: Adopted plumbing code: California Plumbing Code, 2025 Edition. Base model code: 2024 Uniform Plumbing Code. Enforcing office: Building and Safety Division. Fee authority: Gov. Code §§ 66016, 66020. Latest amendment: Ord. No. 4364, Dec. 15, 2025.

Plumbing work performed without the required permit, or that fails to meet the adopted California Plumbing Code, is a City Code violation. Under the city's general penalty provision (Ordinance No. 4006, Section 5), a conviction is punishable as a misdemeanor with a fine of up to $1,000, up to six months in county jail, or both, and each day a violation continues counts as a separate offense. The building official can also suspend or revoke a permit in addition to any criminal penalty.

Building Permits

Pomona requires a building permit for erecting, enlarging, altering, repairing, moving, converting or demolishing a building or structure, administered under the 2025 California Building Code and California Administrative Code adopted by City Code Sec. 74-31. Permit fees are set separately by city council resolution under Government Code Sections 66016 and 66020, not fixed in the ordinance itself.

Key details: Governing section: City Code Sec. 74-31. Adopted code: 2025 California Building Code (2024 IBC base). Admin procedure source: CBC Chapter 1 and CA Administrative Code. Fee authority: Gov. Code §§ 66016, 66020; Sec. 2-924 schedule. Latest amendment: Ordinance No. 4364, Dec. 15, 2025.

Building, enlarging, altering or demolishing a structure without the required permit under the adopted 2025 California Building Code is a violation the building official can cite and stop-work, and, under the Code's general penalty, Sec. 1-7, is punishable as a misdemeanor with a fine up to the Penal Code Section 19 limit, imprisonment up to six months, or both, with each day of continued unpermitted work a separate offense.

Electrical Permits

Electrical work in Pomona is permitted under the California Electrical Code, 2025 Edition, based on the 2023 National Electrical Code, adopted by City Code Sec. 74-31 alongside the city's other construction codes. Permits and fees follow the same administrative process and city council fee resolution as building, plumbing and mechanical work, not a separate electrical ordinance.

Key details: Governing section: City Code Sec. 74-31. Adopted code: 2025 CA Electrical Code (2023 NEC base). Admin procedure source: CBC Chapter 1 and CA Administrative Code. Fee authority: Gov. Code §§ 66016, 66020; Sec. 2-924 schedule. Latest amendment: Ordinance No. 4364, Dec. 15, 2025.

Performing electrical work without the required permit under the adopted 2025 California Electrical Code is enforceable the same way as any other unpermitted construction-code work: the building official can stop the work, and, under the Code's general penalty, Sec. 1-7, a violation is punishable as a misdemeanor with a fine up to the Penal Code Section 19 limit, up to six months in jail, or both, with each day a separate offense.

The Bottom Line

Pomona's building safety rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Pomona is broadly strict or permissive.
