Most comparisons of these two towns start with lot sizes and price. Start somewhere more useful: roughly 88 percent of the land inside the “Waxhaw NC” mailing area is not in the Town of Waxhaw at all. The ZIP covers 106.3 square miles. The town covers 12.9. Before you compare anything else, work out which jurisdiction the specific address is actually in, because it decides the tax bill, the zoning and who picks up the trash.
Quick answer
Waxhaw runs a full municipal government and charges 29 cents per $100. Weddington outsources nearly everything and charges 3.5 cents. Both sit in Union County, both use Union County Water, and a mailing address in either does not tell you which town you are in.
- Combined tax: Waxhaw 0.7242 per $100, Weddington 0.4692. The town portion differs by 8.3 times
- ZIP 28173 is 106.3 sq mi; the Town of Waxhaw is 12.9. About 88 percent of the ZIP is outside town limits
- Weddington zones by minimum lot square footage. Waxhaw has no minimum lot area at all
- Waxhaw was chartered in 1889. Weddington incorporated in 1983 to avoid Charlotte annexation
- Waxhaw has 1,602 approved homes not yet built. Weddington approves subdivisions of 5 to 46 lots
Your address is probably not in the town you think
Waxhaw’s own planning department answers this on its website, and the wording is worth quoting: “My mailing address says Waxhaw, does that mean I live within Waxhaw town limits? Not necessarily. Mailing addresses are often based on historic locations of post offices and do not reflect actual town limits.”
The numbers show how big that gap is. Census figures for 2025 put the 28173 ZIP code area at 106.33 square miles and the Town of Waxhaw at 12.926. The town is about 12 percent of the mailing area. Everything else is unincorporated Union County, or Marvin, or Wesley Chapel.
Weddington’s situation is different rather than better, and I had this wrong at first. Comparing the two areas directly overstates it, because the Town of Weddington straddles two ZIP codes, with roughly a quarter of the town falling inside 28173. Measured properly, about 43 percent of the 28104 ZIP area sits inside Weddington town limits.
The bigger issue in 28104 is not unincorporated land, which accounts for only about 12 percent of it. It is other towns. Stallings, Indian Trail, Wesley Chapel, Matthews and a sliver of Charlotte together make up well over half the ZIP. So a 28104 address is far more likely to be in a different municipality than in unincorporated county, which is the opposite of the pattern in 28173. Note too that the postal city name attached to 28104 is Matthews, even though Weddington Town Hall uses a 28104 address.
Waxhaw maintains a “Do I Live in Waxhaw” page and a public town-limits map for exactly this reason. Use it before you assume anything below applies to a given house.
The tax gap, and the reason for it
Waxhaw’s town rate is 29 cents per $100 of assessed value. Weddington’s is 3.5 cents. That is a factor of 8.3, and it is not because one town is better run than the other. It is because they do different amounts of work.
| Jurisdiction | County | Town | Combined |
|---|---|---|---|
| Town of Waxhaw | 0.4342 | 0.2900 | 0.7242 |
| Town of Weddington | 0.4342 | 0.0350 | 0.4692 |
| Unincorporated Union County | 0.4342 | none | 0.4342 |

Weddington contracts out almost everything. Policing is the Union County Sheriff’s Office under a contract providing five officers. Fire is the Wesley Chapel Volunteer Fire Department. The town states plainly that it maintains no public roads, because NCDOT does. Trash is a private contractor. Water and sewer are Union County.
Waxhaw runs fourteen departments including its own police force, building inspections, a fire marshal, engineering, parks and recreation, public services, code enforcement and a Main Street program, on a general fund of about $26.5 million. You are paying 29 cents for a town that behaves like a town.
On a home assessed at $700,000, the combined difference works out to roughly $1,785 a year. Whether that is a saving or a false economy depends on how much you value having a local government that answers the phone.
They do not even zone by the same unit
This is the part nobody explains properly, and it undermines most of what gets written about lot sizes here.
Weddington regulates by minimum lot area in square feet. Its most common residential district, R-40, requires 40,000 square feet. That is 0.918 acres, not one acre, and the difference matters when someone tells you Weddington is a one-acre-minimum town. It is not. The districts run from 18,000 square feet in the conservation option up to 80,000 in R-80.
Waxhaw has no minimum lot area whatsoever. Its land development code, adopted in 2021, controls density in units per acre together with minimum lot width and depth. R-1 permits one unit per acre with a minimum 100-foot width and 200-foot depth; R-4 permits four units per acre at 60 by 105.
So a straight comparison of minimum lot sizes between the two towns is not possible, because one of them does not have any. Ask about the specific district and the specific parcel.
One more structural point that explains a lot of confusion: Weddington has no extraterritorial jurisdiction. Its 2024 land use plan lists obtaining one as a goal. Its zoning stops dead at the town line, and the land immediately outside is zoned by Union County. That is how a house with a Weddington address ends up on a small lot.
Water, sewer and the capacity problem
Neither town runs its own water or sewer. Union County Water owns and operates both systems in both towns. Waxhaw did once have a municipal system: federal records list it as deactivated on July 1, 1988.
Weddington is often described as having no public sewer at all. That is wrong. The town’s own 2024 plan says the system is expanding within the town but that many parts are not connected and rely on septic. Public water is widespread; sewer is partial. Which one you get is an address-level question, not a town-level one.
The constraint worth knowing about is capacity. As of the figures published in that plan, the Twelve Mile Creek treatment plant was at 94.4 percent of its permitted flow once committed capacity was counted. Waxhaw amended its own code in 2023 to allow private water and sewer connections where public utilities are unavailable or at capacity. Growth here is limited by pipes as much as by zoning.
Different towns, different trajectories
Waxhaw was chartered in 1889 as a railroad town and has a National Register historic district. Weddington incorporated on May 2, 1983, specifically to avoid being annexed by Charlotte, and adopted zoning four years later to protect its rural character. Ninety-four years apart, and it shows in everything.
Weddington’s land is 65.3 percent low-density residential and 0.4 percent commercial, about 48 acres in total, with its future plan calling for 39. Commercial development is permitted only in a downtown overlay. It is zoned to remain a bedroom community and it is doing so deliberately.
Waxhaw more than doubled its population between 2010 and 2020, from 9,915 to 20,534, and as of its most recent code review carried 1,602 approved homes not yet built plus another 1,486 in projects under review. Weddington in the same period grew from 9,207 to 13,181 and approves subdivisions of between 5 and 46 lots.
Price reflects it. Zillow’s home value index for July 2026 put Weddington at $1,059,442 and Waxhaw at $717,174, a premium of about 1.48 times that has widened from 1.37 in 2021. Both were essentially flat year over year. That is a value index rather than a sale price, and Zillow’s town boundaries are its own, so treat it as a directional signal.
The tradeoff
Choose Waxhaw if you want a walkable historic downtown, town services that exist, parks and recreation, and a wider range of price points. Accept that you are paying 29 cents for it, that the town has more than doubled in a decade with over 1,600 approved homes still to come, and that downtown water and sewer mains from the 1930s are being replaced through late 2026.
Choose Weddington if you want larger lots, very low town taxes and almost no commercial development. Accept that the town provides very little directly, that your sheriff coverage is five contracted officers, that your road maintenance is NCDOT’s schedule not the town’s, that sewer may not reach your parcel, and that the entry price is roughly 1.5 times Waxhaw’s.
And in both cases, confirm the jurisdiction before you do any of this arithmetic. For more on each, see Waxhaw and Weddington. If you are ready to compare specific houses, the town guides at The Longleaf Group go deeper on the buying side.
Frequently asked questions
Does a Waxhaw address mean I live in Waxhaw?
Often not. The 28173 ZIP area covers 106.3 square miles while the Town of Waxhaw covers 12.9, so roughly 88 percent of the mailing area sits outside town limits. Waxhaw’s planning department says mailing addresses reflect historic post office locations, not town boundaries. Check the town’s own limits map.
Does Weddington require one-acre lots?
No. Its most common district, R-40, requires 40,000 square feet, which is 0.918 acres. Districts range from 18,000 square feet under the conservation option up to 80,000 in R-80. The “one acre” description comes from the town’s plans describing density loosely, not from the ordinance.
Why are Weddington’s taxes so much lower?
Because it provides far less. Weddington contracts policing to the Union County Sheriff, fire to a volunteer department, road maintenance to NCDOT, trash to a private company and utilities to Union County. Waxhaw runs fourteen departments including its own police force on a general fund of about $26.5 million.
Does Weddington have public sewer?
Partly. The town’s 2024 plan says the sewer system is expanding but many parts of the town are not connected and rely on septic. Public water is widespread. Both systems are owned and operated by Union County Water, not the town. Confirm at the parcel level.
Which schools serve Waxhaw and Weddington?
Both are in Union County Public Schools, a single countywide district. UCPS does not currently offer a working address lookup; its site lists one as coming soon. Check the published attendance boundary maps by cluster and confirm with the district Office of Student Assignment on 704-296-1005 extension 4090.
