Room Additions in Central Florida
Sunologi Inc. is a licensed Florida building contractor (CBC1261200) based in Sanford that builds room additions across Central Florida: bedrooms, primary suites, in law suites, home offices, and garage conversions. An addition is real construction, with foundations, engineering, and a full permit set, and that is exactly what a CBC license covers. Sunologi is the construction division of the AllSolar family of companies, serving Florida homeowners since 1999.
What building an addition involves
Every addition starts with drawings and engineering: a site plan, foundation and framing design sealed by an engineer, and energy code calculations. Then the county reviews and permits the work before a shovel touches dirt. Construction runs foundation, block or frame walls, roof tie in, windows, electrical and HVAC extension, insulation, drywall, and finishes, with county inspections at each stage. We manage all of it, including matching your existing roofline, stucco or siding, and floor heights so the addition does not look like an addition.
What drives the price of a room addition
Additions price by the square foot, and the rate depends on complexity: a simple bedroom on grade sits at one end, a primary suite with a full bath or significant roof rework at the other. Design, engineering, and permitting are part of the real number, not extras. Site conditions matter too: septic locations, easements, and setback lines can change what is buildable, which is why we check them before you spend money on drawings. Every addition is quoted from a site visit with a written line item scope.
How the process runs
Three stages: design and engineering, county review, then construction. We drive all three — drawings move to the county the day they are sealed, and materials are ordered while the permit is in review so construction starts the moment it is issued. You get the full schedule in writing before you commit a dollar, and anyone promising to skip the engineering or the permit is setting you up to pay for it later. Start with a free estimate.
Room Additions: common questions
Do I need a permit for a room addition in Florida?
Yes, always. A room addition requires a building permit with engineered plans, and the work is inspected at every major stage: foundation, framing, electrical, insulation, and final. Unpermitted additions surface at appraisal and sale time and often have to be torn open or removed. We handle the full permit package under our CBC license.
Can I convert my garage instead of building new?
Often yes, and it is significantly cheaper than building new because the slab, walls, and roof already exist. A garage conversion still needs a permit because you are changing the use of the space and adding electrical, insulation, and usually HVAC; adding a bathroom is the biggest swing in the price. Consider resale too: in some neighborhoods losing the garage hurts value, and we will tell you if we think that is true on your street.
Will the addition match my existing house?
That is the standard we build to. We match roof pitch and shingles, stucco texture or siding profile, window styles, and interior floor heights. Texture and paint blending on the connection wall is finish work we plan from the start, not an afterthought.
