Glendale's Building Safety: The Rules That Matter

Every city handles building safety a little differently. In Glendale, Arizona, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Green Building Code

Glendale adopted the 2024 International Green Construction Code as Sec. 9-26 of its municipal code, but the city made every substantive requirement in the code optional. Compliance is left entirely to the design professional's choice on each project.

Key details: Code adopted: 2024 International Green Construction Code. Compliance status: Voluntary, chosen by design professional. Enforcement chapter: IgCC Sections 102-110 deleted. Administered under: 2024 International Building Code instead. Adopting ordinance: Ord. No. O25-51, effective 12-9-25.

Because every substantive IgCC provision is optional, there is no separate citation, fine, or stop-work order tied to a builder's decision not to follow the Green Construction Code's sustainability measures. Any enforcement that does occur runs through the standard International Building Code administrative process (Sections 102-110 of that code), not through a distinct green-code violation, since Glendale deleted the IgCC's own administrative chapter.

Glendale is more permissive than most cities when it comes to green building code. That said, there are still limits.

Electrical Permits

Glendale adopts the 2023 National Electrical Code (NFPA 70) by reference, and any electrical work must be permitted and inspected by the Building Safety Division. Violating the adopted code is a misdemeanor, and certain high-voltage or life-safety installations require an independent special inspector before a certificate of occupancy issues.

Key details: Adopted code: 2023 NEC / NFPA 70. Enforcing agency: Building Safety Division. Violation classification: Misdemeanor. Special inspection trigger: ≥1,000 amps or over 600 volts. Permit fees: Set by council resolution.

Violating any provision of the adopted 2023 NEC is a misdemeanor under § 9-16(b). Starting electrical work before a permit issues triggers a mandatory special investigation under the amended Section 109.5 before a permit can be granted. A suspended or revoked electrical permit cannot be worked under once notice is served, and a revoked permit's fee is not refunded under the amended Section 105.6.

Fire Sprinkler Requirements

Glendale requires an approved automatic sprinkler system throughout the entire building for every newly constructed commercial and residential structure, with the code's only blanket carve-out for one- and two-family dwellings covered by the Residential Code.

Key details: Scope: All new commercial and residential structures. Coverage: Throughout entire building. Exempt: One- and two-family dwellings. Retrofit deadline (Group I-2): 12 months of notice. Penalty: Class 1 misdemeanor.

Fire Code violations, including failing to install a required sprinkler system, are prosecuted under Section 113.4 as a Class 1 misdemeanor. Continued work after a stop-work order triggers an additional fee under Section 114.4, set by city council resolution, on top of misdemeanor liability.

This is not one of those rules that cities tend to ignore. Glendale actively enforces its fire sprinkler requirements requirements.

Building Inspections

Glendale's Building Safety Division inspects work under the adopted 2024 International Building Code at rough-in and final stages for electrical, mechanical, and plumbing systems, plus special inspections on complex work under Section 110.3.11. Section 109.6 lets the city charge a reinspection fee whenever a called inspection finds incomplete work, uncorrected deficiencies, no access, or missing inspection records, and it will not inspect again until that fee is paid.

Key details: Enforcing agency: Building Safety Division. Electrical rough-in inspection: Before conduit/wiring concealed. Plumbing rough-in inspection: Before piping buried or concealed. Special inspections trigger: 1,000+ amp or 600+ volt equipment. Frame inspection standard: Building must be weather-tight.

Concealing building service equipment, electrical conduit, or plumbing before it passes inspection, or connecting service equipment to power, water, gas, or sewer before the building official authorizes it, violates Section 110.3.13. Requesting inspection with the work incomplete, uncorrected deficiencies outstanding, no access provided, or the inspection card unavailable triggers a reinspection fee under Section 109.6, and no further inspection occurs until it's paid.

Building Permits

Glendale requires a permit under the adopted 2024 International Building Code for nearly every construction, alteration, or repair project, enforced by the city's Building Safety Division. Glendale Code § 9-17 exempts only specific items from IBC Section 105.2, including fences 7 feet or under and agricultural hoophouses and polyhouses built under A.R.S. § 9-469. Anything else needs a permit before work starts.

Key details: Adopted code: 2024 International Building Code. Enforcing agency: Building Safety Division. Fence permit exemption: Up to 7 feet high. Hoophouse exemption: Per A.R.S. § 9-469. No-permit work found: Triggers investigation fee, § 109.5.

Working under a permit that has been suspended or revoked is unlawful once the city serves notice on the permit holder, owner, or person in charge of the work, and a revoked permit's fee is not refunded. Violating any provision of the adopted codes under Section 9-16 is a misdemeanor. Starting work before obtaining a required permit triggers a mandatory special investigation and an added investigation fee under Section 109.5, regardless of whether a permit is later issued.

Plumbing Permits

Glendale adopts the 2024 International Plumbing Code by reference, administered by the Building Safety Division, and requires permits for plumbing installations with fees set annually by council resolution. Local amendments set minimum sewer depths, water-closet flow limits, and route sewage disposal issues to the Water Services Department.

Key details: Adopted code: 2024 International Plumbing Code. Enforcing agency: Building Safety Division. Minimum sewer depth: 12 inches below grade. Water closet limit: 1.28 gallons per flush. Violation classification: Misdemeanor.

Violating any provision of the adopted 2024 International Plumbing Code is a misdemeanor under § 9-16(b). Commencing plumbing work before a permit is obtained triggers a mandatory special investigation under the amended Section 109.5 before a permit may be issued, and a suspended or revoked permit bars further work until the building official reinstates it in writing.

The Bottom Line

Glendale'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 Glendale is broadly strict or permissive.
