The Las Vegas market
The City of Las Vegas issues water heater and HVAC replacement permits online without plans. Its permit list includes "Water Heater (Same for same only including Tankless)" and "HVAC exact change outs/repairs," and the permit is issued at the end of the online submission. Either a licensed building contractor or a residential owner-builder can apply, and inspections are booked at LasVegasNevada.gov/ScheduleInspection. Fees were not published in the pages reviewed, so check the city's fee schedule. Henderson, North Las Vegas and unincorporated Clark County each run their own building departments. DOE's Building America guide puts Clark County in hot-dry climate zone 3B, and EIA's 2020 survey found 78% of Nevada homes have central air, 68% heat with natural gas and 67% heat water with gas.
Matching the old tank's size, fuel and spot keeps a Las Vegas water heater job simple. Changing any of those can turn the swap into a bigger job with new venting or gas work. Ask whether the quote names removal of the old tank, any new connectors or venting, and an expansion tank. A tank in a hot garage should sit in a drain pan, so ask about one. Get the tank size and efficiency rating written on the quote.
