Sewall's Point is overwhelmingly single-family and low-density. The housing stock is a mix of mid-century ranch homes, older Florida-style residences, and newer custom-built waterfront estates, with mature landscaping and larger lots than most surrounding communities. Because the town is bordered by water on three sides, a large proportion of homes sit on canals, on the river, or on the lagoon, and boating access is a common feature. The town has historically favored residential character over commercial or multi-family development, so the market remains concentrated at the higher end of the spectrum, oriented toward buyers seeking privacy and water access.

Sewall's Point is a single cohesive residential peninsula rather than a collection of distinct neighborhoods. The oldest streets cluster near the northern approach to the peninsula, while newer streets and cul-de-sacs spread south and east toward the river and lagoon shorelines. A small elevated area once known as Mount Elizabeth, an ancient Indian mound, sits on private land near the town's east side. Throughout, the defining pattern is one of tree-lined residential streets and waterfront lots, with the town's park, town hall, and a few civic spaces concentrated near the center.

Life in Sewall's Point is quiet, private, and oriented toward the water. Boating, kayaking, paddleboarding, and fishing are everyday activities, with the St. Lucie River and Indian River Lagoon serving as the town's back yard. The pace is deliberately slow, with little commercial activity inside town limits. Residents rely on nearby Stuart for shopping, dining, and entertainment, while the town itself offers a close-knit, low-traffic atmosphere. The combination of waterfront living, mature tree canopy, and proximity to the Treasure Coast's beaches makes it a sought-after address for those wanting seclusion without isolation.

Sewall's Point is served by the Martin County School District, which educates students across the county's public schools. The district is regarded as one of the stronger public systems in the region, and families in Sewall's Point send students to Martin County schools in the nearby Stuart and Jensen Beach area. The town's small size means there are no schools within its own boundaries, but the short drive to surrounding campuses is a routine part of daily life for local families.

Sewall's Point is reached by bridge across the St. Lucie River from Stuart, putting the Martin County seat and its U.S. 1 corridor just minutes away. From the east side of the peninsula, the causeway to Jensen Beach and Hutchinson Island connects the town to the Atlantic beaches. The area's road network feeds into Interstate 95 and Florida's Turnpike for travel up and down the coast, while Palm Beach International Airport lies roughly 45 miles to the south. Within the town, traffic is light, and the streets are built for a residential pace rather than through-commuting.

Recreation in Sewall's Point begins at the water. Residents keep boats on the St. Lucie River and the Indian River Lagoon, and the nearby waters are known for fishing, kayaking, and paddleboarding. Just across the causeway, the ocean beaches of Hutchinson Island, including Jensen Beach and Bathtub Reef Beach, are a short drive away. Indian RiverSide Park in Jensen Beach preserves the area's pioneer history, including Captain Sewall's relocated 1889 home. To the south, downtown Stuart provides restaurants, a riverwalk, and marinas, rounding out the town's blend of waterfront and small-city amenities.
