Room Additions in Palm Beach
In Palm Beach, additions concern the 36% of owner-occupied homes that are detached houses, many of them older; condo owners work within their units. For a house, Florida law decides when a large renovation brings in the energy code and whether the town allows accessory dwelling units, so check both before design. Goodhaus connects owners with independent contractors at no charge and does not perform the work itself.
Ideas & Inspiration
Room Addition Ideas to Consider in Palm Beach
General ideas for inspiration only. These are not projects performed by Goodhaus, which is a free matching service and not a contractor.
Energy code on big projects
Florida treats an alteration that changes insulation, cooling, water heating or the exterior envelope and costs more than 30 percent of the structure's assessed value as a renovated building under its energy efficiency rules.
Accessory units
Under Florida law, accessory dwelling units in single-family zones depend on whether the county or city has adopted an ordinance allowing them.
Owner-builder route
Florida lets an owner act as their own contractor on a one- or two-family home for their own occupancy or use, not for sale or lease, if they supervise the work on site and sign the permit application in person.
Costs
How much does a room addition cost in Palm Beach?
Palm Beach addition quotes depend on structural work on an older house, foundation and any flood-related requirements, exterior materials and openings, and the drawings, design review and permits that come first.

Questions
Room Additions in Palm Beach: FAQs
Do flood rules apply to an addition?
If the property is in a mapped flood hazard area, an improvement costing 50 percent or more of the structure's market value is a substantial improvement under the federal flood rules, so ask the floodplain administrator early.
Do I need a permit?
Yes. Under Florida law, constructing or altering a building without a permit is unlawful unless another law exempts the work.
