Which building codes are generally applied to residential construction under a Home Owner Builder program?

• A. The National Electrical Code only.
• B. The International Building Code only.
• C. The applicable local residential code (often IRC with amendments), energy code, fire safety code, and zoning/land-use requirements.
• D. No codes apply.

Answer: (C)

Under a Home Owner Builder program, residential construction is governed by the local code framework, not just a single code. The main requirement is to follow the applicable local residential code, which for most single‑family homes is the International Residential Code (IRC) with jurisdictional amendments. But that's only part of the picture: you also must meet the adopted energy code for efficiency, follow the fire safety code to address fire prevention and protection, and comply with zoning and land-use rules such as setbacks, height limits, and lot coverage. Plans are typically reviewed and inspections conducted by the local building department to ensure all these codes are met. While electrical work is covered by the national electrical and related provisions within the local code package, the overall set of requirements generally includes the local residential code along with the energy, fire, and zoning rules, which is why this option is the most accurate reflection of what applies.
