Garage Additions Across Tampa Bay

A garage addition in Tampa gives you covered parking, a real workspace and storage that gets the bikes, tools and totes out of the living room. Onsite Construction builds attached and detached garages as a design build project, so the same team that draws the plan pours the slab, frames the walls and hangs the door. You deal with one company from the first sketch to the final inspection.

Most Tampa homeowners come to us for one of a few reasons. They want a second bay for another vehicle, a workshop or gym behind the parking, a detached garage at the back of the lot, or a garage with a finished room above for guests or a home office. We size the build around how you actually live, then check it against your lot lines, setbacks and the look of the existing house.

Every project starts with the footprint you already own. We walk the property, confirm where a garage can legally sit, and lay out the slab, the roofline and the door placement so the finished structure reads as part of the home instead of an afterthought parked beside it.

Out of Parking and Out of Storage in Tampa?

The cars bake in the Florida sun, the lawn gear lives on the patio, and there is nowhere to put the kayak, the holiday bins or the second fridge. Renting a storage unit every month adds up, and a carport does nothing for the value of your home. A proper garage solves the parking, the storage and the resale all at once.

Tell us what you need to park and what you need to store, and we will tell you honestly whether an attached bay, a detached garage or a conversion is the right call for your house and your budget.

Why Tampa Bay Homeowners Choose Onsite for Garage Additions

Attached or Detached, We Build Both

Tie a new bay into the house or set a freestanding garage at the back of the lot. We lay out either one around your parking, your access and your setbacks.

It Matches the House

We match the roof pitch, siding, stucco, trim and door style so the garage looks original to the home and not bolted on once the work is done.

Permits and Engineering Handled

A garage in Tampa needs sealed drawings, wind load detailing and city or county permits. We pull all of it and carry the project through inspection.

Built in Tampa Since 2006

Founded and led by Jason Fausette, Onsite has been adding garages, rooms and additions onto Tampa Bay homes for years.

Garage Addition Questions From Tampa Homeowners

Should I build an attached or a detached garage? +
It comes down to your lot and how you want to use the space. An attached garage gives you a dry path straight into the house and usually costs less to run power and roof. A detached garage builder in Tampa can place a freestanding structure at the back or side of the lot, which keeps noise and workshop mess away from the house and often fits better on a corner or irregular parcel.
Can you build a room above the garage? +
Yes. A garage with a finished room above is one of our most requested builds. The bay carries the parking and storage below while the upper level becomes a guest suite, a home office or a bonus room. It does need a deeper foundation and stair access, and our engineer confirms the structure carries the second floor before we frame it.
Do you convert an existing garage into living space? +
We do. A garage conversion in Tampa turns the bay into a bedroom, an in law suite, an office or a den with proper insulation, climate control, flooring and finished walls. Many homeowners then add a new garage elsewhere on the lot so they keep the parking and storage they gave up. We talk through both halves before you commit.
Will the new garage match the rest of my house? +
That is the goal. As your garage addition contractor we match the roof pitch, the stucco or siding, the trim color and the window style so the finished home reads as one build. Done right, the addition looks like it was there the day the house was finished.
How much parking and storage can I plan for? +
Most homeowners start with a one or two car layout and add depth or a third bay for a workshop, a gym or shelving. We map out the door width, the ceiling height for overhead racks and the floor space around the cars so the garage works for parking and storage instead of forcing you to choose.
Do you handle the permits and the slab? +
Yes. A garage addition in Tampa needs sealed structural drawings, a permitted slab and city or county approvals, and our design build process covers all of it. We pour the foundation, frame the structure, schedule the inspections and carry the project through final approval so you are not chasing paperwork.
What areas do you serve for garage additions? +
We build garages across the Tampa Bay region including Tampa, South Tampa, St. Petersburg, Clearwater, Brandon, Riverview, Plant City, Lutz, Wesley Chapel and Carrollwood.
