8 Common Commercial Building Codes That You Need to Know
Most individuals, when approaching their first construction project, are vaguely familiar with building codes, otherwise known as building regulations. The intent of the Building Code is to detail the minimum provisions acceptable to maintain the safety of buildings, with specific regard to public health, fire protection, accessibility and structural sufficiency. It is not a textbook for building design or not an optional element in construction. Building codes are designed to safeguard the health and safety of all occupants in the building.
Knowledge of building codes is an essential factor when choosing a commercial contractor for your next construction project. An experienced commercial construction company will have Strong knowledge of building codes that will ensure your construction/renovation job goes smoothly without expensive mistakes. Implementation of building codes starts early in design process; your commercial construction contractor submits building plans to your City building department and issues building permit to begin construction. The City inspector will verify compliance to these standards during development during field review and issues permits for the inhabitance of the building.

There’s a ton of building code and can be overwhelming for someone with little or no experience. On top of it, additional codes with more specific requirements apply to places of business. If you’re preparing for a commercial construction project, here are the most common 8 commercial building codes that you need to know.
Means of Egress
The means of egress building code governs the number of exits a commercial building must have, as well as the minimum width of aisles, hallways, doorways, and other means of leaving a building. You’ll want to ensure that your building has been designed with the proper sizing and dimensions to conform to the means of egress building codes in your area.
Boring of Framing (plumbing)
Plumbing systems are an integral part of your commercial building. For this reason, building codes dictate the allowable sizes and locations for holes and cuts into studs needed to make room for plumbing in your building. These commercial building codes help to ensure the structural integrity of walls in your establishments.
Labeling of Circuits
It is one of the building code systems that your electrical contractor will follow. It is often overlooked, every circuit and circuit modification shall be legibly identified as to its clear, evident, and specific purposes or use.” Thus, this is an important final checklist item for your commercial contractor to have in place.

The penetrations from electrical, plumbing, HVAC ducts, and vents need to be properly air sealed. Any penetrations, especially the ones that is leading externally, should be sealed using approved material to ensure air cannot pass through the openings.
Fire resistance is another vital area where many commercial buildings fail inspection. Fire rated drywalls, insulations, etc..are used to prevent the spread of fire through the concealed, open cavities in your building. This is a critical fire safety building code.
Reinforcement or Support of Rebar

Having the proper handrail and guard railing height and spacing is another frequent commercial building code violation. The handrail should be between 34-42 in, guard railing shall be not less than 42 in high and evenly distributed vertical load applied at the top of the guard should be 1.5 kN/m.
