Water heater replacement in Santa Fe
The City of Santa Fe lists new and replacement mechanical equipment as permit work and takes Plumbing/Gas and Mechanical permits online, and state rules require the applicable permit for plumbing and mechanical work. The City's page does not name water heaters, so ask the permit counter ([email protected]) or your contractor which permit your swap needs. For a gas heater, check that the contractor's license covers both plumbing and gas.
Do I need a permit to replace a water heater in Santa Fe?
Ask before work starts. The City lists new and replacement mechanical equipment as permit work and offers Plumbing/Gas and Mechanical permits online, and state rules require the applicable permit for plumbing and mechanical work.
The City's building permits page does not name water heaters, so we are not telling you a specific permit is or is not required. Email [email protected], or ask each contractor in writing which permit applies and who will file it. Secondary trade permits can usually be filed without construction drawings, though the City may ask for equipment cut sheets.
What license should my installer have?
For a gas-fired heater, ask for an MM-98 license or both MM-1 (plumbing) and MM-2 (gas fitting). MM-1 alone does not include natural gas appliances or piping.
Check the license number and classification in the NM CID lookup. State rules also require subcontracted work to be performed by a properly licensed entity, so ask who will do the gas connection.
Does the historic district matter for a water heater?
Only if the job changes the exterior. The City says exterior work on structures in its Historic Districts must be pre-approved, and that most simple maintenance and repair work in a Historic District does not require a construction permit.
A new vent, enclosure, or anything visible from outside is worth asking about before the contractor orders equipment. The Historic Preservation Division handles administrative approvals for maintenance and repair; see the City's page.
Replace or repair, tank or tankless?
Storage tanks typically last roughly 10 to 15 years and a tank leaking from the shell cannot be repaired; tankless units are expected to last more than 20 years but may need different venting, gas or electrical work.
Find the date on the tank's label. Ask each contractor to price both options with every required change itemized so quotes can be compared fairly.
What should a quote include?
Equipment, scope, permit responsibility, haul-away, and warranty, in writing.
- Make, model, size, fuel, and efficiency rating.
- Venting, gas connection, shutoffs, and any drain pan or expansion tank the contractor says are needed.
- Who files the City permit and schedules the inspection.
- Disposal of the old unit.
- NM license number and classification, plus warranty terms.
