Room Addition in Riverview, FL
Room additions that look like they were always there. Built to match your existing roofline, siding, trim, and architecture. Not bolted on. Built in.
Riverview has grown rapidly over the past two decades, and many homeowners in communities like FishHawk Ranch, Boyette, and Summerfield are finding that their 2000s-era homes need more space as families grow. The Alafia River creates flood zones along its corridor that affect addition placement on nearby properties. Riverview's newer construction means the existing structure is generally well-suited to accept an addition, with modern trusses, updated electrical, and PEX plumbing already in place. Drome Contracting designs Riverview room additions to match the existing roof pitch, fascia, and siding for a seamless look. All permits go through Hillsborough County Development Services under license CGC1515971.

FAQ
Common Questions
How long does a room addition take in Riverview?
Single room additions take 2-4 months. Multi-room or in-law suites take 3-6 months depending on complexity and Hillsborough County permitting timelines.
Will a room addition match my existing home?
That is the entire point. We match your roofline pitch, siding profile, trim style, and floor elevations. A bad addition is obvious. Ours are not.
Do I need an architect for a room addition?
Not always. Simple bedroom or office additions can be designed with our team. Complex additions or second stories may benefit from architectural plans, and we can coordinate that.
What setback requirements apply to room additions in Hillsborough County?
Hillsborough County enforces minimum setback distances from property lines for any new construction. Typical residential setbacks are 7.5 feet on the sides, 20 feet from the front, and 10 feet from the rear, but these vary by zoning district. We verify your specific setback requirements with the county before designing your addition to make sure the project is approvable.
How do Florida wind load requirements affect room addition framing?
Any room addition in Hillsborough County must meet the same wind load requirements as new construction. This means hurricane straps on every truss connection, properly rated sheathing with specific nail patterns, and impact-rated windows or shutters on all openings. The framing must tie into your existing structure in a way that maintains the wind resistance of the entire building envelope.
Can my existing HVAC system handle a room addition in Riverview?
It depends on the size of your current system and the square footage being added. A typical room addition of 200 to 400 square feet may overload an already right-sized system in the Florida heat. We perform a Manual J load calculation to determine whether your existing unit can handle the additional space or whether an upgrade or supplemental mini-split system is needed.
Do I need a survey before building a room addition in Hillsborough County?
Yes. Hillsborough County requires a current boundary survey showing the proposed addition footprint before issuing a building permit. The survey confirms that the addition will not encroach on setbacks, easements, or neighboring property lines. If your existing survey is more than a few years old, you will likely need a new one.
Can you build a second-story addition over my existing Florida slab foundation?
Sometimes, but it requires a structural engineer to evaluate whether your existing slab and footings can support the additional load. Many Florida homes were built on monolithic slabs designed only for single-story loads. If reinforcement is needed, options include adding steel beams, deepening footings, or installing helical piers. We get the engineering analysis done before providing a final price.
