FREE General Contractor License Building Codes and Standards Questions and Answers

Question 1

A contractor is building a new single-story office space with a calculated occupant load of 65 people. According to the International Building Code (IBC), what is the minimum number of exits required from this space?

Accepted Answer

Two

Answer

The International Building Code generally requires a minimum of two exits when the occupant load of a space exceeds 49. Since the occupant load is 65, at least two exits are mandatory to provide adequate means of egress in an emergency.

Question 2

In the International Building Code (IBC), which construction type is characterized by non-combustible exterior walls and interior building elements made of solid or laminated wood without concealed spaces (heavy timber)?

Accepted Answer

Type IV (Heavy Timber)

Answer

Type IV construction, often called Heavy Timber (HT) or 'mill construction', requires noncombustible exterior walls and interior structural elements made of heavy timber. This design provides a degree of fire resistance by using large-dimension wood members that char slowly in a fire.

Question 3

A general contractor is installing an access ramp to the entrance of a public library. To comply with the Americans with Disabilities Act (ADA) Standards for Accessible Design, what is the maximum allowable running slope for the new ramp?

Accepted Answer

1:12 (1 inch of rise for every 12 inches of run)

Answer

The ADA Standards for Accessible Design mandate that the maximum running slope for a ramp in new construction cannot be steeper than 1:12. This ratio ensures the ramp is not too steep for individuals using wheelchairs or other mobility aids.

Question 4

A contractor has completed the foundation and slab-on-grade for a new retail store, including the installation of under-slab plumbing and electrical conduit. Before proceeding with wall framing, which of the following inspections is typically required?

Accepted Answer

Footing and Foundation Inspection

Answer

The footing and foundation inspection is performed after excavation and placement of forms and reinforcement but before concrete is poured. In many jurisdictions, this also includes an under-slab inspection for plumbing and electrical work that will be concealed by the slab. This must be approved before framing can begin.

Question 5

A project's plans are governed by both a state-adopted building code and a more restrictive local municipal amendment. In a situation where the local code requires a higher fire-resistance rating for a specific wall assembly than the state code, which requirement must the contractor follow?

Accepted Answer

The more restrictive local municipal amendment

Answer

When building codes are adopted, the rule is to follow the most restrictive requirement. Local jurisdictions (cities, counties) can amend state or model codes, and if their amendment is stricter, it takes precedence for all construction within that jurisdiction.
