Master Suite Additions Across Tampa Bay

A master suite addition Tampa homeowners ask us for usually means three things in one new wing: a larger bedroom, a private bathroom and a walk in closet that finally holds everything. Onsite builds that whole footprint as a single addition tied into your roofline, your wall framing and your home's existing systems so it reads like it was always there, not bolted on the side.

Most of the primary suite addition projects we take on in Tampa start with families who love their neighborhood and their lot but have outgrown a 1970s or 1980s bedroom. Rather than buy a bigger house in this market, they add the space they actually need. We have built owners suite additions on slab homes, raised block homes and second story bump outs across South Tampa, Carrollwood and the Pinellas side.

From the first sketch through the final coat of paint, you work with one builder. We draw the layout, pull the permits with the city or county, frame and dry in the addition, run the plumbing and electrical, and finish the bath and closet down to the tile and trim.

Tired of Fighting Over One Small Bathroom?

You are sharing a single sink, stepping over each other to get ready, and the closet gave up years ago. Buying a larger home means new taxes, a new commute and a market that fights back. A master bedroom addition Tampa families can grow into is almost always the smarter move.

Tell us how you live and what the space needs to do. We will tell you what fits on your lot, what the city will allow and what it really costs before you commit to anything.

Why Tampa Bay Homeowners Choose Onsite for Master Suites

Layouts That Flow With the Home

We tie the new suite into your hallway, roofline and floor height so it does not feel like a separate box. The walk through from your living space into the suite stays natural.

Bath and Closet Built In House

Tile, glass shower, double vanity, soaking tub and a custom walk in closet are all framed and finished by our crew. You are not chasing four subcontractors yourself.

We Handle Tampa Permitting

Additions need engineered plans and permits. We prepare the drawings, submit to the city or county and carry the project through inspections so you are not stuck at a permit counter.

Building in Tampa Bay Since 2006

Founded and led by Jason Fausette, Onsite has added square footage to homes across Hillsborough and Pinellas for nearly two decades.

Master Suite Addition FAQs

What does a master suite addition include? +
A full primary suite addition usually includes an enlarged bedroom, a private bathroom and a walk in closet. We can also add a sitting area, a coffee bar or French doors to the backyard depending on your lot and budget.
How much does a master suite addition cost in Tampa? +
Cost depends on the square footage, whether it is ground level or a second story, and the finishes you pick for the bath and closet. After we see your home and your lot we give you a written number, not a guess over the phone.
How long does a master bedroom addition take? +
Most master bedroom addition projects in Tampa run about three to five months from permit approval through the final walkthrough. Design and permitting before that can add several more weeks, which we map out for you up front.
Do I need a permit to add a master suite? +
Yes. Any addition that adds living space, plumbing and electrical needs engineered plans and a building permit from the city or county. We handle the drawings, the submittal and every inspection through final approval.
Will an owners suite addition add value to my home? +
An owners suite addition tends to add real resale value because buyers in Tampa want a true primary bedroom with its own bath and closet. It also lets you stay in the home and neighborhood you already like.
Can I stay in my house during the build? +
Usually yes. Because an addition is built onto the outside of the home, most of the work happens behind a new wall before we tie it into the existing rooms. We seal off the work area and keep your current bedroom usable as long as we can.
Can you match the new suite to my existing home? +
Yes. We match the roofline, exterior finish, window style and interior trim so the addition blends in from the street and inside. The goal is for it to look original to the house.
