01Uniform Mechanical Code
The Uniform Mechanical Code is a minimum-requirements document. It applies to the installation, alteration, repair, replacement, maintenance, and removal of mechanical systems, including heating, ventilating, exhaust, air-conditioning, refrigeration, hydronic, and fuel-gas piping within its scope. The exam tests whether you can locate the governing rule, not whether you can design a system from memory. Definitions control meaning: approved means acceptable to the authority having jurisdiction (AHJ); listed means included in a recognized listing agency directory; labeled means bearing the listing mark.

The UMC does not make the inspector the designer, but it makes design assumptions visible. Check that the appliance input rating, fuel type, altitude, and category match the listing and the venting method. Ducts must be sized and installed to deliver the required airflow; flexible duct must be supported, not compressed, and protected from damage. Refrigerant systems are classified by refrigerant safety group; the installation must match the listed equipment and the occupancy limits.

Mechanical inspection is staged: rough-in before concealment, final after completion. At rough-in, verify support, clearances, duct sealing, vent slope, combustion-air openings, and access. At final, verify appliance listing, labeling, controls, clearances, termination, and operational tests. Concealed work that was not inspected may need to be exposed; the permit holder bears that cost.
359 words, about 2 min04Administration, Permits and Code Enforcement
A permit is the legal authorization to perform regulated work. The application identifies the scope, the contractor, and the property; submittal documents must be adequate to show compliance. The AHJ may require plans, calculations, and equipment listings before issuing the permit. Work within the permit scope may proceed; work outside it requires an amended permit.
