One Community, Two Counties

A resident’s guide to the line you can’t see, and what it means for your taxes, roads, and services
Facts current as of August 21, 2026. Tax rates, budgets, and project schedules change; dates are noted where it matters.
Two neighbors in Sun City Hilton Head can share a golf course, a pickleball schedule, and a favorite table at the same restaurant, and still live under different county governments. One gets a tax bill from Beaufort County. The other hears from Jasper County, possibly with a City of Hardeeville line on the bill as well. They may vote in different elections and use different library systems. Inside the gates, nothing marks the boundary. Outside them, it matters.
That invisible line explains a lot about what is happening around the community right now: why one side is growing so much faster, why “which side is cheaper” is harder to answer than the folklore suggests, and why some road projects are under construction while others are still just ideas in a plan.
The short version:
- The community name tells you nothing official. Your address determines your county, taxes, voting districts, and services.
- Jasper County is growing about three times as fast as Beaufort, but Beaufort remains more than five times larger.
- Nobody has proven which side is cheaper to live on. The popular comparisons get the tax math wrong.
- Big road money is in motion: Jasper’s program is approved, Beaufort’s goes to voters this November, I-95 work is underway, and the new light at the Sun City West entrance is approved and in design (no official switch-on date yet).
- Many of the systems that matter most, including water, hospitals, hurricane planning, and emergency response, already operate across the county line.
The rest of this guide fills in the details, and ends with a checklist for answering the questions that depend on your own address.
Start with the address, not the label
“Sun City” is a community name, not a jurisdiction. A mailing address or ZIP code does not tell you which county a home is in, whether it sits inside Hardeeville’s city limits, or which tax districts apply.
What the records do show: the community spans both counties, and Hardeeville’s zoning library lists planned development districts for the Argent 2 and East Argent Sun City tracts, meaning the city has a formal planning role over those Jasper-side sections (Hardeeville zoning). A planned development district is a custom set of zoning rules negotiated for a large project.
What the records do not show is the exact profile of any particular home. For that, three sources are authoritative: your tax bill, your parcel record, and your voter registration at MySCVotes. When in doubt, trust those over neighborhood shorthand.
A mature county beside a growth frontier
The two counties are on very different paths, and a few numbers tell the story.
| Beaufort County | Jasper County | |
|---|---|---|
| Population (July 2025 estimate) | 204,433 | 38,533 |
| Growth, 2020 to 2025 (estimate) | 9.3% | 33.7% |
| Residents 65 and older | 31.2% | 28.0% |
| People per square mile (2020) | 325 | 44 |
Source: Census QuickFacts for both counties. These are countywide figures, not a profile of Sun City households.
In plain terms: Beaufort is the larger, older, more built-out county. Jasper is much smaller and mostly rural, but it is adding people at a remarkable rate, and most of that change is concentrated in and around Hardeeville.
How much more is coming? Hardeeville’s own development ledger is the best public answer (Residential Pipeline, June 2026):
| Hardeeville pipeline, June 2026 | Units |
|---|---|
| Maximum allowed under development agreements | 49,258 |
| In master plans | 20,103 |
| Building permits issued | 9,000 |
Those three numbers describe three different stages, and the difference matters. The 49,258 figure is a ceiling, the most that existing agreements would ever allow, not a forecast. Master plans are closer to reality, and permits closer still. Within the pipeline, the Sun City tracts themselves are nearly built out: Argent 2 shows 1,480 planned units with 1,396 permits issued, and East Argent shows 1,540 planned with 791 permits.
So no, fifty thousand homes are not on the way. But the growth pressure on the community’s western side is real, documented, and trackable through public records.
Who is planning what
Three governments hold the pens around the community, each with its own playbook.
Beaufort County works from Envision Beaufort County 2040, adopted in 2021 and now getting its five-year update (the plan). A comprehensive plan sets long-term priorities without committing money. The companion Action Playbook goes further, proposing a new Okatie-area library, expanded EMS capacity near Sun City at William Pope Drive, and formal three-way coordination with Jasper County and Hardeeville on the SC 170 corridor. These are proposals, not funded construction.
Jasper County is updating its 2018 plan, Jasper’s Journey, and has proposed an overlay district to manage growth in the rural Euhaw area; that proposal had not been confirmed as final law at press time (county planning pages).
Hardeeville governs the fastest-changing ground through its development districts and a budget that reflects a city building itself out: $93.3 million total for FY2027, including $29.4 million for capital projects (budget release).
The detail worth noticing: Beaufort’s playbook explicitly proposes working across the county line on SC 170. The governments know what residents experience daily. Traffic and drainage do not stop at the county sign.
Read the bill, not the myth
Ask around and you will hear confident claims about which side is “cheaper.” The record supports something less satisfying and more useful: nobody has actually established an answer, and the usual comparisons get the mechanics wrong.
South Carolina property tax works in layers. An owner-occupied primary home (a “legal residence” in tax language) is assessed at 4 percent of market value; most other property is assessed at 6 percent. A mill is one dollar of tax per thousand dollars of assessed value, so on a $100,000 legal residence, ten mills equals $40 before credits. Legal residences are exempt from school operating taxes, though school debt still applies. And residents 65 and older who qualify get the state Homestead Exemption, which removes the first $50,000 of market value from taxation (SCDOR).
Here are the county-adopted levies, with a large caution: this is not a complete tax bill for either side.
| Adopted levy | Mills |
|---|---|
| Beaufort County operating, FY2027 | 59.5 |
| Jasper County operating, FY2026-27 | 115.0 |
| Jasper County debt | 5.0 |
| Jasper school operating (legal residences exempt) | 154.0 |
| Jasper school debt | 25.0 |
| Jasper Rural Fire, where it applies | 28.9 |
Sources: Beaufort FY2027 budget; Jasper adopted budgets.
Why can’t you just compare those numbers? Three reasons. The Beaufort figure is the county government’s portion only; Beaufort homes also pay school, fire, and other district levies not shown here. A Jasper-side home inside Hardeeville may add a municipal layer (the city’s final FY2027 rate was not yet verified). And Jasper’s local-option sales tax generates a credit that lowers property-tax bills, which millage tables ignore entirely.
The honest bottom line: comparing the two sides requires two actual tax bills, for comparable homes, in the same year, with all exemptions and credits applied. Anything less is folklore.
Sales tax is simpler. The general rate is 6 percent in Beaufort County and 9 percent in Jasper (SCDOR), though unprepared food is exempt from two of Jasper’s three extra pennies, so the grocery gap is smaller than the headline suggests.
The roads: what’s real, what’s funded, what’s just a plan
Road projects climb a ladder: long-range plan, ballot proposal, funded program, design, construction. Each rung is real news, but only the top ones move traffic. Here is where things stand, starting with the item closest to home.
Approved and in design: the new light at the Sun City West entrance. The long-discussed traffic signal at Sundance Drive and Argent Boulevard is a documented City of Hardeeville project, and it is moving. SCDOT gave the city written approval on February 13, 2026 to proceed, after traffic studies confirmed the intersection qualifies for a signal under the state’s criteria (city announcement). The city’s detailed proposed FY2027 capital plan carries it as a $550,000 project, $50,000 for design and $500,000 for construction, funded by developer agreement fees, the payments builders make to the city under their development deals (FY2027 proposed budget book, pp. 150-151). And by April 28, 2026, the city had advertised for an engineering firm to design it (procurement listing), so the project has moved past approval and into design. It is a separate project from the US 278/Sun City signal on Beaufort County’s November ballot; that one is a different intersection, a different government, and still awaiting a vote.
So when does it light up? The honest answer is that no official date exists. A November 2026 estimate has circulated among residents, but no published schedule or project milestone supports it; hitting that date would require the design award, state plan review, permits, construction bidding, and equipment delivery all to go quickly. Judging from the milestones that are public, the first half of 2027 is the more credible planning assumption, and later remains possible if reviews, bids, or hardware run long. The city’s previous signal, on Latitude Boulevard, offers useful perspective on why these projects take time: it ran about a year from engineering authorization to construction, with the city attributing much of the wait to a 30-to-40-week manufacturing lead time for the mast arms that hold the signal heads. Different project, possibly different equipment, but the same multi-step process. Every date beyond the completed steps is an estimate, not a commitment; the next hard news to watch for is a design award, and after that a construction contract.
Under construction now. SCDOT is rebuilding I-95 from mile markers 0 to 8, including bridge work at the Savannah River and SC 46. John Smith Road is closed for bridge replacement through late 2026. The next stretch, mile markers 8 to 21, is in design, with construction expected in 2027 (SCDOT project pages).
Approved and funded. Jasper County voters passed a 1 percent transportation sales tax in November 2024, running up to 15 years and estimated at $470 million: $376 million for roads and $94 million for greenbelt land purchases. Program documents earmark $57 million for Argent Boulevard and $65 million for two stretches of US 278 between the county line and I-95 (county referendum materials). Funded, yes; but each project still has to move through design and construction individually.
On the ballot. Beaufort County voters decide on November 3, 2026 whether to approve an eight-year transportation sales tax estimated at $780 million: $326 million for safety and intersections, $205 million for widening, and $249 million for resurfacing and dirt-road paving. The project list includes SC 170, SC 46, US 278, and a traffic signal project at US 278 and Sun City (official referendum page). Nothing is funded until the vote passes, which also makes this the one item on this list where residents still have a direct say.
On the long-range map. The regional transportation planning body for the two counties, called LATS, maintains 20-year plans that set priorities and eligibility (LATS). Useful, but a long-range plan is not a construction schedule.
Emergencies: the nearest truck, not the nearest boundary
Emergency response is one place where governments have deliberately worked around the line. On the Beaufort side, Bluffton Township Fire District’s Station 34 on William Pope Drive houses both a fire engine and Beaufort County EMS, and the district broke ground in May 2026 on Station 39 at 301 Sun City Boulevard, its tenth station (Bluffton Fire District).
In southern Jasper County, Hardeeville’s Operation Phoenix coordinates dispatch so the closest available engine or ambulance responds whenever possible, regardless of whose name is on the truck (Operation Phoenix).
Two things to keep straight. In an emergency, call 911; the coordination happens behind the scenes. And closest-unit response does not change which fire district taxes your property, so your nonemergency contacts are still worth confirming by address.
Shared systems, shared exposure
Some of the most important services never respected the county line in the first place.
Water and sewer come from the Beaufort-Jasper Water & Sewer Authority, a two-county utility whose history includes the original Del Webb Sun City service agreement. Its current master plan, adopted in May 2026, plans regional investment 20 years out (BJWSA), so the Hardeeville growth described above is already factored into utility planning.
Hurricanes are planned regionally too. The state’s Know Your Zone system covers both counties and models Beaufort, Jasper, and Colleton as one southern evacuation region (SCEMD). One point deserves emphasis: being on the Jasper side, farther from the beach, does not make a home safe from flooding. Flood risk, insurance, and evacuation zones are set property by property, not county by county.
Hospitals crossed the line in 2024, when Novant Health bought Hilton Head Hospital and Coastal Carolina Hospital in Hardeeville as part of a $2.4 billion purchase (Novant). Novant has also won state approval for a new 50-bed hospital in Bluffton, expandable to 100 beds, currently scheduled for 2028. Shared ownership makes health care a regional story, though it does not by itself prove anything about quality of care, and 2028 is a schedule, not a promise.
Conservation shows the two counties at different stages of the same idea. Beaufort’s decades-old land preservation program reports more than 25,000 acres protected (county update). Jasper’s greenbelt program is brand new, created by the 2024 referendum with $94 million set aside but no acquisition record yet. That is a difference in maturity, not in values.
The everyday details where the line reappears
A few practical services split cleanly by side:
| Beaufort side | Jasper side | |
|---|---|---|
| Trash | County convenience centers (Beaufort residents only) or private curbside haulers | Hardeeville residents enroll with Capital Waste Services; county drop-off centers serve unincorporated areas |
| Library | Beaufort County Library (Bluffton Branch, 120 Palmetto Way) | Allendale-Hampton-Jasper regional system (Hardeeville branch, 30 Main Street) |
| County council | 11 members, single-member districts | 5 members: 4 township seats plus 1 at-large |
Sources: county and city service pages (Hardeeville, Beaufort, Jasper, library systems, county council pages).
Two open questions worth knowing about: whether a Community Association contract standardizes trash collection for particular neighborhoods, and whether one side’s library card works at the other side’s library. Neither is settled in the public record, so check directly before assuming. Hardeeville residents also vote in city elections on top of county ones.
Your address checklist
The most accurate answer to “which side is better?” is a set of better questions, each with an official source:
- County and parcel: your county assessor’s parcel record.
- City status: Hardeeville’s current city-limits map for Jasper-side homes.
- Tax bill and districts: your current tax notice, including any city, fire, or special-district lines and the Jasper local-option credit.
- Legal residence and Homestead status: your county auditor, using state eligibility rules.
- Voting: MySCVotes for your districts, precinct, and polling place.
- Fire, EMS, police: 911 in any emergency; confirm nonemergency contacts by address.
- Trash: your city, county, or association arrangement.
- Evacuation zone and flood risk: Know Your Zone and current flood maps for your property.
- Water and sewer: your BJWSA account.
The county line will not become more visible any time soon. But residents who know which record answers which question can navigate both sides of it with confidence.
What to Watch
- The Argent/Sundance signal. Design procurement began in April 2026; the milestones that will pin down a real date are a design award, state plan and permit approval, a construction contract, and equipment delivery. Until those land, the first half of 2027 is an estimate, not a schedule.
- November 3, 2026: Beaufort County’s $780 million transportation referendum, including the separate US 278 signal project at Sun City.
- Hardeeville’s pipeline reports, the best public measure of how much entitled growth is actually advancing to plans and permits.
- Road projects already funded or underway: Jasper’s Argent Boulevard and US 278 allocations moving into design and construction, and I-95 (mile markers 0-8 under construction, 8-21 expected to start in 2027, John Smith Road closed through late 2026).
- Beaufort’s comprehensive plan update and the Novant Bluffton hospital, currently scheduled for 2028.
