The Orlando market
The City of Orlando's Permitting Services Division does not publish a plain statement that replacements need permits, but its forms imply it: the plumbing application has water heater checkboxes, and the mechanical application has a Repair/Replace work type with fields for system type, tonnage and SEER2. Florida's Building Commission has also held that replacing a water heater needs a permit absent a local exemption. Mechanical fees are $66.24 for the first $1,000 of construction cost plus $11.03 per additional $1,000, residential plumbing and gas is $66.24 plus $7 per fixture, and a 3% technology surcharge applies. Registered licensed contractors apply, or owners with a notarized signature for stand-alone work. Inspections are scheduled through the PROMPT phone system. Kissimmee, Sanford and Orange County issue their own permits.
Few Florida homes have gas, so a gas tankless install in Orlando usually starts with whether gas reaches the house at all. An electric tankless unit needs heavy wiring and possibly a panel upgrade. Either way, the infrastructure tends to cost more than the heater. If the job runs over $2,500, expect the city to want a Notice of Commencement before the first inspection. Ask for the amp draw or gas input in writing.
