Water heater replacement in Alexandria, VA
Alexandria is two conversations at once: the City of Alexandria, which has its own permit office, and a ring of Fairfax County neighborhoods that still have an Alexandria mailing address. Fairfax Water Heaters covers both, but the paperwork is not the same.
First: which Alexandria?
If your tax bill or assessment is the City of Alexandria, permits go through the city’s APEX system and the Department of Code Administration (Permit Center). Gas water heaters need a permit under Virginia’s statewide rule. Do not assume an electric swap is exempt until you check the city’s current permit requirements.
If your assessment is Fairfax County — common in several 223xx ZIP codes that say “Alexandria” on the mail — the job is a Fairfax County PLUS job, not a city job. This mix-up is one of the easiest ways to send the permit to the wrong office. Check the jurisdiction first — it decides which portal the permit goes through. The permits guide has the full split. We walk you through the permit steps.

Old Town, townhouses, and West End closets
- Older city rowhouses and tight basements (including Old Town and nearby historic blocks) often have limited access, older vents, and little extra room for a larger tank or a heat pump’s airflow. Historic exterior rules are usually not about an interior water heater, but anything that changes a sidewall vent still has to be planned.
- Del Ray and similar early-20th-century streets often have a basement tank and an older flue shared with a furnace.
- West End condos and mid-rises tend to be closet installs, with association rules and pan-drain questions that look more like Arlington than like a Fairfax County split-level.
Tell us the neighborhood and where the unit sits. Replacement and closet notes apply here more often than a wide-open garage swap.

FAQ
My mail says Alexandria, but I think I am in the county. Does it matter?
Yes, because the permit office changes. Include the ZIP and, if you know it, the jurisdiction on your tax bill.
Are condos covered?
Yes, as long as the address is in our coverage and we can work within the building’s rules. Share those rules on the form.
