Based on demand alone, if there’s one area in the Lowcountry in need of new homes, perhaps Mount Pleasant is at the top of the list.

The real estate hotbed has among the region’s lowest inventory of homes for sale. Last month’s activity didn’t help matters, as the town accounted for nearly a third of the 635 sales in Charleston County, according to a new report.

To at least try to ease the supply squeeze, developers are once again busy building new homes in Mount Pleasant.

The latest to announce is FrontDoor Communities, which is planning to build four homes in the 82-acre Watermark development of commercial space and residential housing near Rifle Range and Bowman roads. FrontDoor plans to start construction within weeks on the single-family residences, which will be priced in the $400,000 range, according to its website.

This isn’t the only East Cooper project for the Atlanta-based developer, which was formed by former John Wieland Homes & Neighborhoods executives. FrontDoor is also adding homes in its Tributary at Rivertowne off S.C. Highway 41. It’s also involved in Lubert Adler’s Bridgeside II mixed-use waterfront project next to Patriots Point Naval & Maritime Museum.

FrontDoor is among a slate of builders looking to capitalize on the demand for housing in Mount Pleasant. Others projects in the works include Ryland Homes’ Tupelo development off U.S. Highway 17, near Wando High School.

Tupelo is a short distance from Carolina Park, which is also adding more homes and recently announced it’s working with three more builders: Cline Homes, Sabal Homes and Saussy Burbank.
