Selling Your Coral Gables House to a Builder
A lot of older houses in Coral Gables sell for the land under them. When a builder looks at a 1950s ranch on a 10,000-square-foot lot in the Riviera, the first question isn’t the kitchen or the roof. It’s how big a house the city will allow on that lot. That number drives the price.
We’re one of those builders. Future Generation Homes buys single-family houses across Coral Gables and builds the new homes ourselves.
Why the Lot Sets the Price in Coral Gables
When a house is bought to be rebuilt, the buyer is paying for what can go on the lot, not for what’s standing there now. The condition of the house doesn’t matter. We buy as-is.
That’s how we price. We start from what current zoning lets us build on your lot and work back from there.
How Much House the Coral Gables Zoning Code Allows on Your Lot
Maximum Floor Area by Lot Size
Coral Gables caps the size of a single-family home based on lot size. The limit is 48% of the first 5,000 square feet of the lot, 35% of the next 5,000 square feet, and 30% of anything beyond that.
| Lot size | Maximum floor area |
|---|---|
| 5,000 sq ft | 2,400 sq ft |
| 7,000 sq ft | 3,100 sq ft |
| 10,000 sq ft | 4,150 sq ft |
| 12,000 sq ft | 4,750 sq ft |
| 15,000 sq ft | 5,650 sq ft |
| 20,000 sq ft | 7,150 sq ft |
Because the percentage drops as the lot gets bigger, doubling the lot doesn’t double the house. A 20,000-square-foot lot allows 7,150 square feet, not 8,300.
Floor area counts every floor of the house. Open porches don’t count, and neither do small detached garages and carports in the back yard. The thickness of the exterior walls is also left out.
Height, Lot Coverage and Setbacks
- Height: two stories, and 25 feet to the top-floor tie beam. In low-lying areas the floor can be raised to meet FEMA flood rules.
- Lot coverage: the main house can cover at most 35% of the lot, and at least 40% has to stay open space.
- Front setback: 25 feet on most streets, 35 feet on boulevards 70 feet wide or more, and 50 feet on Granada Boulevard.
- Side and rear setbacks: at least 5 feet on each side, with both sides together adding up to 20% of the lot’s width. The rear setback is 10 feet.
Board of Architects Review
Every new house in Coral Gables goes before the city’s Board of Architects, which can require changes to the design before a permit is issued.
What Raises or Lowers Land Value in Coral Gables
- Lot size and frontage. You need at least 50 feet of street frontage to build, and some streets require more. Those street-specific rules are in Appendix A of the Zoning Code.
- The street. A deeper front setback on a boulevard or on Granada leaves less of the lot to build on.
- Corner lots. The side facing the second street has its own 15-foot setback, which takes a bite out of the buildable area.
- The neighborhood. Lots of similar size sell for very different money in different parts of the Gables. In the Riviera, where a typical lot is 10,000 square feet, the median sale over the past two years was about $2.5 million. In Coral Bay, where a typical lot is 12,000 square feet, it was about $5 million.
- Flood elevation. Houses in low-lying areas have to be raised to meet FEMA rules, which adds to the cost of building.
Where New Construction Is Going Up in Coral Gables
Most Coral Gables houses were built before 1980. Of the city’s 10,646 single-family homes, 82% were built in 1979 or earlier.
County property records show 75 new single-family homes completed in Coral Gables in 2024 and 2025. Nearly half went up in three neighborhoods:
| Neighborhood | New homes, 2024–2025 | Median sale, past 2 years | Typical lot |
|---|---|---|---|
| Riviera (33146) | 18 | $2.5 million | 10,000 sq ft |
| Country Club (33134, 33146) | 9 | $2.4 million | 11,000 sq ft |
| Coral Bay (33156) | 9 | $5.0 million | 12,000 sq ft |
North Gables, the Biscayne Bay Section and Cocoplum each had a handful more.
How to Sell Your House to a Builder in Coral Gables
We buy every single-family house in Coral Gables, whatever its age or condition. You don’t repair, clean, or tear anything down. Our offer is based on what your lot allows, and once we own it, we build the new house ourselves.
In Coral Gables, the city’s Historic Preservation Officer has to sign off before any house can be demolished, under Zoning Code Sec. 8-107(G). We request that sign-off on your behalf while the house is under contract, and the contract depends on it. After closing, we pull the demolition permit as the owners and take the house down. You don’t file anything with the city.
If the house has open permits or older work that was never permitted, see our guide to selling a house with open permits or unpermitted work in Miami. For a cash offer, call (786) 400-2628 or fill out the form to sell your house in Coral Gables for cash.
