Serving Tampa Bay
Building additions in Tampa Bay
Florida building requirements, wind and flood considerations and setbacks all affect what you can build and how. Some Tampa Bay properties are in flood zones or have lot constraints that shape the design.
Permits go through the local jurisdiction, such as the City of St. Petersburg, the City of Tampa, Pinellas County or Hillsborough County. We find out what applies to your property and manage permitting and inspections.

Frequently Asked Questions
Home addition FAQs
How much does a home addition cost?
Cost depends on the size, design, foundation, structural requirements, finishes and what systems are involved. We provide a written estimate after reviewing your plans and property.
How long does a home addition take?
Additions take longer than interior remodels because of permitting, engineering and multiple construction phases. We give a realistic schedule during planning.
Do I need a permit for an addition?
Yes. Additions require permits and inspections. We coordinate the process with your local jurisdiction.
Will the addition match my existing home?
That is the goal. We match rooflines, exterior finishes, windows and interior details so the addition looks like part of the original home.
Can I live in my home during construction?
Usually yes, though there will be noise and dust, and some days may limit access to certain areas. We discuss this during planning.
Does my property flood zone affect my addition?
It can. Flood zone, elevation and setback requirements can affect design and cost, so we review them early.
