Two Story Home Additions Across Tampa Bay

A 2 story home addition in Tampa lets you grow inside the footprint you already own. Instead of selling and buying back into a rising market, you stack new square footage over a garage, a single story wing or the back of the house. Onsite Construction plans the whole thing as a design build project, so the same team that draws it is the team that pours the footings and hangs the final door.

Adding up is the smart move on a tight Tampa lot. A second story addition keeps your yard, your driveway and your setbacks intact while doubling the living space below it. We have added primary suites, kids' wings, home offices and bonus rooms over existing structures from South Tampa to Wesley Chapel.

Every project starts with a structural review of what is already standing. We check the foundation, the existing framing and the load path before a single new wall goes up, because the floor below has to carry the weight of the floor above for the life of the home.

Outgrowing Your Tampa Home but Hate the Idea of Moving?

A growing family, a new baby on the way, parents moving in, a work from home setup that took over the dining room. The space stopped fitting and the listings in your neighborhood cost a fortune. Building up gives you the room you need and keeps you in the home and zip code you already chose.

Tell us what you are trying to gain and we will tell you honestly whether adding up or building out makes more sense for your house and your budget.

Why Tampa Bay Homeowners Choose Onsite for Second Story Additions

Design Build Under One Roof

Architecture, engineering and construction sit on one team. No finger pointing between a designer and a builder when the plans meet the framing crew.

We Read the Structure First

Before we promise a second floor we confirm the foundation and existing framing can carry it. If they cannot, we price the reinforcement honestly up front.

Your Roofline Stays Right

We match pitch, soffit, siding, brick and window style so the new story looks original to the house, not bolted on after the fact.

Built in Tampa Since 2006

Founded and led by Jason Fausette, Onsite has been adding onto Tampa Bay homes for years and knows the local permitting and inspection process.

Two Story Addition Questions From Tampa Homeowners

Should I add up or build out? +
It depends on your lot and your foundation. Building out is simpler but it eats your yard and runs into setback limits on smaller Tampa parcels. A second story addition keeps the yard and is often the only way to add real space on a tight lot, though it needs the structure below to support the new load.
Will my existing foundation hold a second story? +
Sometimes yes, sometimes it needs help. Our engineer reviews the slab or footings and the existing framing to confirm the load path. If reinforcement is needed we tell you before you commit, so there are no surprises mid build.
Can I live in the house while you add the second floor? +
Often yes. We seal off the work zone, protect the lower floor and stage the project so your kitchen, baths and bedrooms stay usable for as long as possible. There is usually a short window during the roof opening when staying elsewhere is safer, and we plan that with you in advance.
How long does a two story addition take in Tampa? +
Most projects run several months from permit to final inspection, depending on size and scope. Design and Tampa permitting take time on the front end, then framing the new story, dry in, mechanicals and finishes follow. We give you a real schedule before demolition starts.
Will the new story match the rest of my house? +
That is the goal. As your two story addition contractor we match the roof pitch, siding, trim, brick and windows so the finished home reads as one cohesive build. Done well, visitors cannot tell where the original house ends and the addition begins.
Do you handle the permits and engineering? +
Yes. A home addition in Tampa needs sealed structural drawings and city or county permits, and our design build process covers all of it. We pull the permits, schedule inspections and carry the project through approval so you do not have to chase paperwork.
What areas do you serve for home additions? +
We build additions across the Tampa Bay region including Tampa, South Tampa, St. Petersburg, Clearwater, Brandon, Riverview, Plant City, Lutz, Wesley Chapel and Carrollwood.
