Typical Residential and Commercial Construction Inspections. Residential Inspection Residential Building Inspection: • Structural components (foundations, framing, walls, roofs) • Building materials and construction methods • Means of egress (exits, stairs, ramps) • Fire-resistant construction • Energy efficiency • Accessibility requirements where applicable Residential Plumbing Inspection: • Water supply and distribution systems • Sanitary drainage and venting systems • Fixtures, faucets, and appliances • Water heaters and hot water supply systems • Storm drainage and sump pumps • Pipe materials, installation, and support • Traps, interceptors, and backflow prevention • Minimum fixture requirements and spacing Residential Mechanical Inspection: • Heating and cooling equipment (furnaces, boilers, heat pumps, AC systems) • Duct work installation, materials, and sealing requirements • Ventilation systems, including whole-house and local exhaust • Chimneys, vents, and combustion air requirements • Fuel gas piping and appliances • Fireplaces, solid fuel-burning appliances, and their clearances • Refrigeration systems and condensate disposal • Safety controls, shutdown switches, and protection devices ---PAGE BREAK--- Residential Electrical Inspection: • Electrical service, grounding, and bonding • Branch circuits, wiring methods, and conductor sizing • Overcurrent protection (circuit breakers, fuses) • Panel boards, disconnects, and distribution systems • Receptacle, lighting, and switch installation • GFCI and AFCI protection requirements • Electrical requirements for kitchens, bathrooms, garages, and outdoor spaces • Smoke and carbon monoxide detectors • Special systems (low-voltage, generators, pools, spas, HVAC wiring) Commercial Building Inspection Commercial Building Inspection: • Structural components (foundations, framing, walls, roofs) • Construction materials and fire-resistive assemblies • Means of egress (exits, stairs, ramps, accessibility) • Occupancy classification and allowable building heights/areas • Fire-resistance and life safety provisions • Energy efficiency requirements • Special inspections and structural integrity compliance • Accessibility requirements per ADA and IBC Commercial Plumbing Inspection: • Water supply and distribution systems • Sanitary drainage, venting, and waste systems • Plumbing fixtures, appliances, and minimum facility requirements • Grease traps, interceptors, and backflow prevention devices • Storm drainage systems, roof drains, and sump pumps • Pipe materials, installation methods, and support requirements • Medical gas and specialized plumbing systems hospitals, laboratories) ---PAGE BREAK--- • Commercial water heaters and hot water supply systems • Special occupancies and high-capacity plumbing systems restaurants, hotels, stadiums) Commercial Mechanical Inspection: • Commercial heating, ventilation, and air conditioning (HVAC) systems • Duct work installation, materials, and fire/smoke dampers • Ventilation systems, including commercial kitchen exhaust and makeup air • Combustion air requirements for fuel-fired appliances • Refrigeration systems and cooling towers • Boilers, pressure vessels, and steam systems • Chimneys, vents, and flue gas exhaust systems • Fuel gas piping and appliances (where IMC overlaps with the International Fuel Gas Code – IFGC) • Fire and smoke protection systems related to mechanical components Commercial Electrical Inspection: • Electrical service, grounding, and bonding • Panel boards, switch gear, and distribution systems • Branch circuits, wiring methods, and conductor sizing • Overcurrent protection (circuit breakers, fuses) • Lighting, receptacle, and switch installations • Emergency and standby power systems • GFCI and AFCI protection requirements • Special occupancies (hazardous locations, healthcare, industrial settings) • Low-voltage systems (fire alarms, security, data, communication wiring) • Electrical requirements for elevators, HVAC systems, and commercial kitchens
