What does it cost to build a house in Delray Beach in 2026?
As of November 2026, building a new house in Delray Beach costs an estimated $230 to $495 per square foot before the lot, depending on how high-end the house is.
The estimate, and what builders declare.
Groundbreak’s build calculator prices a house by what homes like it sell for: $230 a square foot at builder grade, up to $495 for ultra-luxury.
Build cost by tier
$ per sq ftTested against 83 recorded Delray Beach build-and-sell deals: with these build costs the calculator's land budget is a median 98% of what the builders actually paid for the lot, and within 25% of it on 47 of the 83 (the old defaults came to 85%).
The declared value is the builder’s own figure for the construction work, and it sets the permit fee. It leaves out the lot and often much of the real cost, so read it as a floor, not a budget.
Both are per square foot of the tax roll’s total building area, garage and covered areas included, which runs larger than the area under air.

How the numbers work
Where the calculator’s build costs come from, and how they’re tested against recorded sales: the lot calculator.
Declared values are from new-home permits on Delray Beach eServices; lot and sale prices from recorded deeds on the county parcel roll; square feet are the tax roll’s total building area.
