I'On is a planned New Urbanist community designed by the architects behind Seaside, Florida, featuring required front porches, enforced architectural variety, and 30% preserved open space — built on land the I'On family owned since 1697.

Jacob Bond I'On (1782–1859) had an unusual resume for a plantation owner. At Yale, his roommate was John C. Calhoun, the future Vice President. I'On commanded Fort Moultrie during the War of 1812, spent six years as President of the South Carolina Senate, and in 1819, hosted President James Monroe at his Hobcaw plantation. That plantation is now this neighborhood.

The family connection goes back further. Jacob's great-grandfather, David Maybank II, acquired the Hobcaw Creek property in 1697. His maternal grandfather, Captain Jacob Bond, emigrated from Cornwall, England. The pronunciation "EYE-on" likely evolved from "Iron" softened by the Lowcountry accent, which drops Rs.

The I'On family cemetery, restored in 1996, is still here. A monument Jacob Bond I'On erected in 1854 stands among the homes.

In April 1995, developers Vince and Tom Graham purchased the "Cottage Tract" of old Hobcaw and enlisted Dover, Kohl & Partners alongside Duany Plater-Zyberk (DPZ)—the architects behind Seaside, Florida—to create something rare in suburban South Carolina: a walkable neighborhood where you actually know your neighbors.

The design philosophy shapes everything:

• Front porches required — Homes face the street, not the garage
• No two homes alike — Architectural review enforces variety
• Streets designed for 20 MPH — Sharp bends ("deflections") calm traffic without gates
• 30% open space — Parks, trails, lakes, and marsh preserved throughout
• Mixed housing types — Cottages to estates on the same block

This isn't a subdivision where a national builder repeated the same four floorplans. It's a community designed by urbanists who studied what makes historic Charleston neighborhoods work—and built those principles into every street.

Homes in I'On range from $1.3M to $5M, with most sales between $1.7M and $3M at approximately $766 per square foot — more than triple the broader Charleston market average.

I'On averages $766 per square foot, up 25% year-over-year. Properties typically sell within 45-60 days, with sellers accepting around 94% of list price on average. With roughly 4 months of inventory, the market is balanced — neither the frenzied bidding wars of 2021 nor a buyer's market.

At $1.3M you get the entry point — a 3-4 bedroom home around 1,800 sqft on a smaller interior lot. At $2M, expect 2,500-3,500 sqft with well-appointed finishes. Above $3M, homes are 4,000+ sqft with water views or larger yards.

Yes — properties along canals or with marsh views command a 10-20% premium over comparable interior lots. If dock access or water views matter to you, expect to pay for the privilege — and expect strong resale demand when you sell.

No. I'On is fully built out at approximately 750 homes with no planned expansion. Unlike typical Mount Pleasant subdivisions where a new phase or competing development can dilute demand, I'On's inventory is fixed. This scarcity — combined with the architectural controls that prevent any one home from dragging down the aesthetic — is why I'On has held value through market cycles.

Exception: Occasional teardown-rebuilds occur, but these replace rather than add inventory.

I'On is a walkable, community-oriented neighborhood with optional club amenities, a scratch bakery, trails, and a front-porch culture where neighbors know each other by name.

The I'On Club operates as a separate membership (open to non-residents too) and is the social hub:

• 6 clay tennis courts and 4 pickleball courts
• 3 outdoor saline pools including a lap pool
• 2 fitness studios with personal training available
• The Lido — A Lowcountry-Mediterranean restaurant overlooking the pools
• Full programming: junior camps, swim school, tennis leagues, fitness classes

Membership runs approximately $2,100 initiation plus $175/month for families—modest compared to country club fees elsewhere, and entirely optional. Many residents join; some don't. Neither is unusual.

For boaters, the Creek Club offers a community dock and boat ramp on Hobcaw Creek, with membership costs varying by boat size. The 5,000+ square foot clubhouse—with exposed rafters, fireplaces, and a lawn overlooking the marsh—is also a popular venue for weddings.

The walkability isn't theoretical. Residents walk to:

• Bakies at I'On — A scratch bakery in a converted house, known for almond shortbread cookies and custom cakes. Open Tuesday through Saturday.
• Pocket parks and trails — Connections to Mount Pleasant's broader trail system
• The village square and amphitheater — Site of community events throughout the year
• Neighbors' front porches — By design, the most common destination

The I'On Trust organizes community events—holiday gatherings, educational programs, volunteer opportunities—that give the calendar a rhythm beyond individual households.

Residents describe it as "how life used to be." Kids ride bikes. Evening walks are routine. Neighbors know each other's names. Dolphins surface in the creeks. Herons stalk the marsh edges.

It's not for everyone—if you prefer privacy and anonymity, the front-porch culture will feel intrusive. But for those who moved here seeking community, it delivers.

I'On is 6-10 miles from downtown Charleston, a 14-16 minute drive via the Arthur Ravenel Jr. Bridge, and about 10 minutes from Sullivan's Island beach.

The Arthur Ravenel Jr. Bridge connects you to downtown Charleston and the peninsula. Sullivan's Island — the quieter, more residential beach — is the quick escape. Isle of Palms and its broader beach scene is slightly farther.

Rush hour caveat: The Ravenel Bridge and Highway 17 can add 10-15 minutes during peak commute times (7-9 AM, 4:30-6:30 PM).

Within Mount Pleasant, you're minutes from:

• Mount Pleasant Towne Centre — Major retail, dining, groceries
• Belle Hall Shopping Center — Additional retail and restaurants
• Shem Creek — Waterfront dining and the local shrimping fleet

Close enough to Charleston for dinner or a show, far enough for quiet streets and a slower pace.

Most of I'On sits in FEMA Zone X (low-to-moderate risk) at 7-25 feet elevation, averaging around 19 feet. Properties along Hobcaw Creek and marsh edges fall in Zone AE (high risk), requiring flood insurance with a federally backed mortgage.

Exception: Properties with elevation certificates may qualify for reduced premiums even in Zone AE. Always verify the specific flood zone for any lot before purchasing.

I'On is zoned for James B. Edwards Elementary, Moultrie Middle School, and Lucy Beckham High School — all rated A by Niche and part of the Charleston County School District.

Lucy Beckham High, which opened in 2020, is the newest high school in the district and has quickly built a strong reputation. Families also have access to Charleston's private school options, with several within reasonable driving distance.

For specifics on test scores, programs, and enrollment, the Charleston County School District website provides current information — and we're happy to connect you with families in the neighborhood for firsthand perspectives.

Note: School zones can change. Verify current zoning through the Charleston County School District before purchasing.

I'On HOA dues are approximately $1,800 per year (~$150/month), plus transfer fees at sale: seller pays 0.10% to I'On Trust and buyer pays 0.15% to I'On Assembly.

What's not included: I'On Club membership (~$175/month for families) and Creek Club membership are separate and optional. Many residents join; some don't.

Annual dues of $1,800/year ($150/month) cover common area maintenance, landscaping, and community operations. Compared to resort-style communities with $400-600/month HOA fees, I'On's dues are modest — and they don't include club memberships.

All exterior changes require approval from the I'On Design Committee (IDC) — including paint colors, additions, fencing, landscaping modifications, and outbuildings. Interior renovations do not require approval.

The review process is the reason no two homes look alike and no one has installed a chain-link fence or painted their house lime green. It's the enforcement mechanism behind the neighborhood's coherent aesthetic.

For some buyers, this is a feature—asset protection. For others, it's a dealbreaker. If you want complete autonomy over your property's exterior, I'On is not the right fit.

IDC Contact: 843-606-6366 (Monday-Wednesday 9am-4pm, Thursday 9am-1pm)

I'On is an excellent fit for buyers who prioritize walkability, architectural quality, and community — but the compact lots, $1.3M minimum, and mandatory architectural review mean it's deliberately not for everyone.

• You value walkability — Rare in suburban SC, and it's built into every street here
• Architectural variety matters — You appreciate that no two homes look alike
• Community appeals to you — Front-porch culture, events calendar, knowing your neighbors
• You want amenities without resort fees — Club access at reasonable rates, not mandatory $500/month
• You're a family with kids — Safe streets designed for 20 MPH, strong schools, community feel
• You're downsizing but want connection — Empty nesters who don't want isolation

• You want a large, private lot — I'On lots are compact by design; that's the walkability tradeoff
• Your budget is under $1.3M — That's the current floor for entry
• You prefer organic historic character — I'On is intentionally designed; if "planned" bothers you, look at Old Village
• You want zero oversight — Architectural review is non-negotiable here
• Immediate beach access is essential — Sullivan's is 10 minutes, not 10 steps

Both are top Mount Pleasant neighborhoods, but I'On offers planned New Urbanist design with modern amenities while Old Village has authentic pre-20th century historic character with a less structured feel.

Neither is "better." They serve different buyers. If you're torn, tour both—the right one becomes obvious quickly.

• The I'On Club — Tennis, pools, fitness, and dining memberships
• I'On Design Committee — Architectural review and guidelines
• Charleston County School District — School enrollment and performance data
