Old Greenwich is the only Index area above $1,000 a square foot

Old Greenwich and Riverside had close median single-family sales—the middle price of the year’s sales—at $3.11M and $2.98M. Their prices per square foot were $161 apart. The houses, their sizes and their settings were not interchangeable.

A smaller denominator can change the comparison

Price per square foot connects a transaction price to recorded house size. It does not separately value the land, remove the benefit of a waterfront position, or assign the same value to every room. A small house on valuable land can post a higher per-foot price than a larger house that costs less in total.

That makes the measure useful for describing a market, but incomplete for valuing a property. Compare layout, condition, finished space, lot characteristics and access before applying one area’s figure to another house.

The size record also matters. The Index uses the assessor’s current house size. Where a house has been enlarged, the earlier sale is divided by that larger current area, making earlier years read slightly low. A historical per-square-foot comparison needs that qualification.

Villages are not additional towns

The Old Greenwich and Riverside figures use U.S. Census Bureau place boundaries. Both sit within Greenwich. Their rows should not be added to the Greenwich total or treated as separate municipal housing markets.

Old Greenwich recorded 69 single-family sales in 2025 and Riverside 76. Publishing an annual median change requires 60 sales in each comparison year. Old Greenwich had 56 in 2024, so the Index withholds its annual change; Riverside’s is published at +2.3%. The current-year count alone does not determine eligibility.

Easton’s $342 figure came alongside a $951K median and 98 sales. Redding was $355 per square foot, with a $1.03M median and 107 sales. These figures give buyers a starting point for comparing acquisition budgets and house size. They do not establish the operating cost of the land, the condition of the systems or the work required after purchase.

Start with the property’s usable space

For a specific comparison, reconcile the assessor record with plans, permits and the actual house. Identify what the stated area includes. Then examine whether the rooms, circulation and finished areas serve the intended use. More recorded square footage does not automatically create more useful space.

The Connecticut Index shows the price levels together. Its $1,065-to-$342 spread is a description of recorded 2025 transactions, not a price list for a square foot of Connecticut real estate.
