Hilliard at a glance for homeowners
Hilliard is a city in Franklin County on the northwest side of the Columbus metro and is part of Norwich Township. The 2020 census counted 37,114 residents, and the Census Bureau's 2020-2024 American Community Survey estimates about 38,000 people living in roughly 14,900 housing units. Most homes use the 43026 ZIP code, but a 43026 mailing address does not by itself prove a property sits inside city limits, so check the parcel's taxing district with the Franklin County Auditor before assuming which rules apply.
How old are Hilliard homes, and why it matters
Census estimates put the median Hilliard home at 1997, which makes the housing stock younger than many Columbus neighborhoods. Roughly 43 percent of units were built in 2000 or later and about 27 percent in the 1990s, while around 21 percent predate 1980. Local history explains the mix: three large subdivisions arrived in the 1950s, a connection to the Columbus regional water and sewer systems in the 1960s opened land for building, and the I-270 outerbelt brought another wave of growth in the 1970s. Older houses near Old Hilliard and the Norwich Street historic district may have original drain lines and aging shutoff valves; newer subdivisions more often raise questions about water heaters reaching the end of their service life and furnaces original to the build.
Who handles your water, sewer and gas
The City of Hilliard states that it does not provide water services itself. The Columbus Division of Water provides water and sanitary sewer service to Hilliard residents and handles starting or stopping service, billing, meter questions, water leaks on the public side and emergency turn-offs. Natural gas in Hilliard comes from Columbia Gas of Ohio, and electricity is delivered over AEP Ohio's lines. The city's own guidance is blunt about private plumbing: drains in your yard and home are the homeowner's responsibility, and the city recommends contacting a plumbing company for those problems.
Hilliard permits for plumbing, water heater and furnace work
Hilliard's Building Standards Division issues building permits, approves plans and performs inspections, and applications are filed through the city's OpenGov online portal. The city lists plumbing and furnace replacement among projects that need a permit, and the Ohio Board of Building Standards shows Hilliard as enforcing plumbing locally rather than through the county health department. Every contractor working in Hilliard must be registered with the Building Department, and the homeowner is responsible for making sure contractors pull the necessary permits. Replacing or repairing a sewer or water lateral is handled separately through the city's Engineering Division.
Winter problems Hilliard homeowners call about
Cold snaps are when frozen pipes in exterior walls, crawl spaces and unheated garages show up, often while the furnace is working hardest. If heat stops, check the thermostat, its batteries and the filter, but do not open burner compartments or bypass safety switches. If a pipe has split, close the main shutoff only if you can reach it safely, and never thaw a pipe with an open flame.
Choose the right Columbus service guide
Each problem has its own guide with safety steps and questions to ask a provider: emergency plumbing for active leaks and burst or frozen pipes, water heater repair for no hot water or a leaking tank, drain and sewer for backups and slow main lines, and HVAC and furnace repair for no-heat calls. Links to all five, plus the Columbus hub, appear in the related resources below.
Hilliard homeowner checklist before you call
- 1If you smell gas, leave the house and call 911 or Columbia Gas of Ohio from outside before calling anyone else.
- 2For a leak on the street side of the meter, or to have water turned off at the curb, contact the Columbus Division of Water, which serves Hilliard.
- 3Ask the provider whether it is registered with the Hilliard Building Department and who will pull the plumbing or furnace permit through the city portal.
- 4Write down which fixtures or rooms are affected, when the problem started and whether the home is in Old Hilliard or a newer subdivision, since pipe age can change the diagnosis.
Common homeowner questions
Do I need a permit to replace a water heater or furnace in Hilliard?
Hilliard lists plumbing and furnace replacement among the projects that need a permit from its Building Standards Division, and applications go through the city's online portal. Confirm the exact requirement for your project with the city, and ask your contractor to handle the permit.
How can I check whether a contractor can work in Hilliard?
Hilliard requires every contractor working in the city to be registered with its Building Department, and residents can contact Hilliard 311 to check a contractor's registration. Ohio Service Hub does not license, register or rate providers.
Are Hilliard homes likely to have older plumbing?
Most are relatively young: the Census Bureau's median year built for Hilliard is 1997. About one in five homes predates 1980, though, and houses around Old Hilliard and the Norwich Street historic district can be far older, so original drain lines and valves are worth asking about.
Who is responsible for a clogged sewer lateral at a Hilliard home?
The city's guidance says drains in your yard and home are the homeowner's responsibility. Repairing or replacing a sewer or water lateral also requires a permit from Hilliard's Engineering Division, so ask the plumber whether that permit is part of the job.
