Definition:
A building code is a set of regulations established by local or state governments specifying minimum standards for construction, renovation, and maintenance of buildings to ensure safety and quality.

Example:
When renovating her kitchen, Maria’s contractor must follow local building codes, ensuring electrical wiring, plumbing, and structural changes comply with safety standards. If her renovations don't meet these codes, she could face fines or be required to redo the work.

Explanation:
Building codes exist to protect public safety, health, and general welfare by defining standards for design, construction, materials, and structural integrity. They cover everything from electrical wiring and plumbing to fire safety, ventilation, energy efficiency, and structural stability. Local inspectors enforce codes, reviewing plans before construction begins, inspecting projects during construction, and approving final work before occupancy.

In real estate transactions, code compliance is critical—homes failing to meet building codes may face delays, repairs, or even restrictions on selling or financing.

Importance:
Understanding building codes matters greatly for homeowners, buyers, and sellers. For buyers, compliance ensures the home is safe, structurally sound, and properly constructed, protecting investments and ensuring insurance coverage. Sellers must ensure properties meet code standards to avoid transaction delays, reduce liability, and enhance home marketability.

In short, awareness of building codes helps homeowners maintain safe, compliant properties, avoiding costly problems or legal issues down the road.
