What is the Arizona Building Code

The Arizona Building Code is the building compliance and safety regulations used when developing and renovating homes, offices, buildings, and other public infrastructures in the state.

However, unlike other states, Arizona does not have a state wide building code. Instead, each local jurisdiction is allowed to enforce its building code based on the International Building Code (IBC).

Most jurisdictions in the state, including Phoenix, adopt the 2018 International Building Code with location specific amendments as the standard for construction projects. As such, glass railing system design and installations across the state are widely based on the 2018 IBC.

Where Glass Guardrails are Required

Glass guardrails perform the same function as traditional railings. Therefore, glass railing systems perform the function of guardrails by providing support and protecting users from falling off elevated platforms.

Beyond support, framed and frameless glass railings are safe and offer several benefits, which include ease of installation and maintenance, improved space aesthetics, and an unobstructed view. Considering these advantages, more people are installing glass deck railings on indoor and outdoor elevated spaces, including stairways, ramps, balconies, and terraces.

The basic glass railing safety regulations widely adopted in the wider Arizona Building Code include the following.

• All elevated platforms that are 762 mm (30 inches) higher than the base walking floor must have glass guardrails or other railing systems.
• Glass railing systems must cover the open sides of elevated platforms and not have openings wider than a diameter of 100 mm (4 inches) except for passing service installations like electric wires and plumbing pipes.
• Guardrails above a specific height must not have openings and projections that support climbing.

These building safety compliance guidelines are widely used across most of Arizona State. However, be sure to check with your local regulation agencies for specific safety regulations.

Glass Railing Requirement

Glass guardrail requirements are highlighted in the general Arizona Building Code. Although each locality has a slightly different version of the code, they converge in some compliance guidelines, including railing height, glass panel quality, pool enclosure glass railing enclosure.

These specifications are crucial for the safety of users, especially children who do not understand danger.

Glass Railing System Height

The height of framed and frameless glass railings is enshrined in all building codes across North American countries. It ensures building safety and functionality based on the IBC glass railing safety regulations.

Here are the railing height requirements for framed and frameless glass railings.

• Glass guard railings in residential buildings must be at least 914 mm (36 inches) in height.
• For commercial buildings, glass railing systems should be a minimum of 1067 mm (42 inches) high.

To support young children and disabled people, most localities require handrails to be placed between 864 mm (34 inches) and 965 mm (38 inches).

Glass Panel Specifications

Glass panels must conform to specific safety regulations to be suitable for use in guardrails. Some of these critical glass railing requirements include the following.

• A minimum thickness of 6 mm (0.2 inches) is acceptable for glass railing systems. However, most frameless glass guard railings are 12 mm (0.5 inches) thick.
• Glass railings require fully tempered or heat-strengthened glass panels complying with Class A of ANSI Z97.1 or Category II of CPSC 16 CFR Part 1201 standards.
• Guardrails can also have glass panels with single fully tempered glass complying with Class A of ANSI Z97.1 or Category II of CPSC 16 CFR Part 1201 standards.
• Shade and color are not essential when it comes to glass railing panels for guardrails. What is critical is for glazing to be physically and structurally free of defects.

Pool Enclosure

Different local versions of the Arizona Building Code share a lot in common when it comes to pool enclosures. These similarities are partly due to federal safety regulations that require swimming pools to be inaccessible to unauthorized users.

Pool fencing is necessary for below-ground and above-ground swimming pools. These glass railing requirements are highlighted below.

• Some municipalities in Arizona require glass guardrail fencing to be at least 1219 mm (48 inches) high. However, cities like Phoenix and other locations mandate a minimum fencing height of 1524 mm (60 inches).
• All swimming pool fencings must not have openings wider than 100 mm (4 inches) in diameter.
• Pool enclosure gates must have self-latching and self-closing devices.
• A glass panel thickness of 12 mm (0.47 inches) or higher is preferred for glass pool enclosures.

Differences in Local Arizona Building Codes

Although most cities and towns have adopted the 2018 International Building Code, differences exist between individual codes, which are based on microclimate, topography, zoning safety regulations, historical preservation, and building types. Some of the differences in the Arizona Building Code for glass railings include the following.

• Phoenix has additional building safety for glass railings in playgrounds, pools, and rooftops. In addition, high temperatures in the desert must be considered when designing and installing railing systems.
• Tucson also experiences extreme temperatures, which necessitates the need for extra care when designing and installing systems. Likewise, excessive UV exposure and strong seasonal winds mandate the use of really thick glass panels.
• Frequent wildlife activity in Scottsdale must be accounted for when selecting glass panels and framing structures. As such, appropriate finishing and coating are required to keep glass railings aesthetically pleasing and functional.
• On the other hand, Sedona has many hillsides and steep terrain properties, which require stringent safety regulations for glass railing installation.

Conclusion

The Arizona Building Code is a useful document for designers, engineers, and architects in the state. Yet, each municipality has a slightly different version of the building code, which is largely based on the 2018 International Building Code.

In each case, glass guard railings are required in elevated platforms, which include balconies, terraces, patios, and more. More specifically, glass panel and railing height compliance guidelines allow for the installation of safe buildings.

Similarly, swimming pool enclosures made of glass railing systems must conform to local glass railing requirements. However, special building safety guidelines may be in place due to differences in topology and microclimate.
