Home Addition FAQs
How much does a home addition cost in Florida?
Typical additions run $150–$400+ per square foot depending on complexity — second stories and wet spaces (kitchens, baths) sit at the higher end. We provide detailed budgets during feasibility.
Do additions need permits and engineering?
Yes — additions are structural work requiring engineered plans, permits, and staged inspections. Our team handles all of it.
How long does a home addition take?
Most single-story additions take 3–6 months of construction; second-story additions typically run longer. Design and permitting come first.
Will an addition add value to my home?
Well-built additions that add bedrooms, bathrooms, or living area typically raise appraised value significantly — especially in South Florida's space-constrained neighborhoods.
