If a Sanford water heater is leaking from the tank, producing rusty water or failing often, a replacement is usually the right call. Permits in Sanford and the rest of Lee County come from one combined inspections office. Call the number on this page to be connected with a local plumber in Sanford.

Who issues the permit in Sanford?
The City of Sanford and Lee County share an Inspections Division that serves Sanford, Broadway and the unincorporated county. Permits are applied for online through its CSS Portal, and the office can be reached at 919-718-4654. Its page doesn't spell out water heater rules, so let the plumber confirm what your replacement needs and pull the permit. A plumber who works in Lee County regularly will know the routine, including how inspections are scheduled after the new heater is in.
My house is older. Will the swap be more complicated?
Possibly. Sanford's housing is older than the Wake County suburbs: Census survey figures show a median year built of 1985, with about 44% of homes before 1980. In houses from that era, around the Downtown Sanford and Rosemount-McIver Park historic districts and similar neighborhoods, the heater may sit in a hall closet, utility room or basement corner with original valves and connectors. The plumber will usually replace those, correct the relief valve line if it doesn't run to a safe spot, and check the vent on a gas unit. A tight closet can limit the tank size that fits, so measure the doorway and the space if you're thinking about going bigger.
Gas or electric: what should I replace it with?
Usually the same fuel you have now, since that avoids new gas piping, venting or wiring. Lee County has natural gas mains, but the fact sheet for this page couldn't confirm which utility serves Sanford, so check the name on your gas bill. If you smell gas at any point, leave the house and call 911 or your gas utility from outside. Switching from gas to electric means a dedicated circuit; going the other way means a gas line to the heater and a vent. Heat pump electric heaters are another option where there's open space and airflow.
A note on Sanford water
Sanford's water and sewer have been run by TriRiver Water since July 1, 2024, when the name changed from City of Sanford Public Utilities. Its annual water quality reports are posted on TriRiver's site; we couldn't open the latest one for this page, so look there for disinfectant and hardness details. Whatever the chemistry, new connectors and washers are a sensible part of any swap.
