What size gas line do you need for a residience?

The size of the gas line needed for a residence typically depends on the total BTU (British Thermal Unit) demand of all gas appliances. Commonly, a 3/4-inch gas line is sufficient for smaller homes with moderate gas usage, while larger homes or those with multiple high-demand appliances may require a 1-inch line or larger. It's crucial to consult local building codes and possibly a professional to ensure proper sizing and installation based on specific needs.
