Room Additions in Boca Raton
In Boca Raton, a room addition is an option for the 63% of owner-occupied homes that are detached houses; condo owners are limited to what their association allows inside the unit. For houses, check how Florida's permit, accessory unit and homestead tax rules apply before design. Goodhaus does not do the work; it is a free service that puts owners in touch with independent contractors; it does not build.

Room Addition Ideas to Consider in Boca Raton
General ideas for inspiration only. These are not projects performed by Goodhaus, which is a free matching service and not a contractor.
Accessory units
Florida law lets each county or city adopt an ordinance allowing accessory dwelling units in single-family zones, so check the city's code before planning one.
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.
Rear family room or suite
A one-story addition starts with the setbacks and any homeowners' association rules; check both first.
Costs
How much does a room addition cost in Boca Raton?
Boca Raton addition quotes depend on size, foundation, roof tie-in, utility runs, exterior openings and the drawings and permit review that come first.

Questions
Room Additions in Boca Raton: FAQs
How will an addition affect my property taxes?
Florida assesses an addition to homestead property at just value as of the first January 1 after substantial completion; ask the Palm Beach County Property Appraiser how your project will be treated.
