Tuff Shed Home Additions & ADU: The Orlando Owner’s Guide
We install Tuff Shed home additions and ADU conversions across Orlando at a typical price of $45,000 to $130,000, depending on the size of your structure, the condition of the slab, and how far we need to run plumbing and electrical. A well-built Tuff Shed can absolutely become a livable addition, but in our experience, most Orlando owners discover the hard way that the factory shell was never engineered for Florida’s insulation, moisture, and permitting requirements. They usually call us after they’ve already spent money on a shed and now realize it needs a foundation upgrade, a vapor barrier, and a lot more than they planned for. If that’s where you are, you’re in the right place.
At Mason Remodeling Co Orlando, we’re an independent service provider, not affiliated with Tuff Shed. We work on their structures regularly, and we know exactly what it takes to turn one into finished, permitted living space in Orlando and the surrounding metro area.
Which Tuff Shed Models This Applies To

Most Tuff Shed home addition and ADU projects in Orlando start with their larger structures, typically the Premier and Pro series in the 10×16 to 14×40 size range. We also work with the Tall Barn and Ranch styles, which give you the ceiling height needed to run insulation, ductwork, and lighting without making the space feel claustrophobic. If your shed has 2×4 wall framing and a standard truss roof, it can usually be converted. If it has 2×3 walls or a thin metal frame, you’re looking at a much bigger job because Florida code won’t let you insulate those walls to the R-value required for air-conditioned living space.
One compatibility gotcha we hit often: Tuff Shed floors are typically built on 4×4 pressure-treated skids sitting right on the ground or on a few concrete blocks. For an ADU in Orlando, that’s not enough. You need a proper stem wall or slab foundation with termite treatment and a moisture barrier under the entire footprint. We can pour a new foundation and set the shed onto it, or if the shed is already in place, we’ll lift it and pour underneath. It’s not a one-day job, but it’s the difference between a structure that lasts 10 years in Florida humidity and one that rots from the bottom up.
Styles & brands we work with







Signs Your Tuff Shed Home Additions & ADU Is Failing
- Condensation and mildew inside the walls. Tuff Sheds are built as storage, not as climate-controlled space. Without a vapor barrier and proper insulation, Florida humidity condenses inside the wall cavities and you get black mildew on the interior paneling within the first year.
- A floor that bounces or sags. The original skid foundation settles unevenly in Orlando’s sandy soil, especially after summer rains. If you notice a door that won’t close square or a low spot in the center of the floor, the foundation is the problem, not the framing.
- Doors and windows that stick or jam. This is usually the structure settling or swelling from moisture. If two or more openings stick at once, the shed has moved and it’s not coming back on its own.
- An electrical system that trips breakers or flickers. If someone ran power out to the shed with a single 20-amp circuit, that’s not enough for a mini-split, a mini-fridge, and a few outlets. You’ll see constant tripping and voltage drops.
- Roof leaks at the ridge or at the wall connection. Tuff Shed roofing is not designed for the volume of rain Orlando gets in summer. Once water gets past the ridge cap or around the eave edges, the OSB roof decking starts to swell and soft, and you have a rot problem.

AfterReplacement Cost & What’s Included

For a Tuff Shed addition or ADU conversion in Orlando, here’s what we see across the metro:
- Foundation pour and shed re-set: $6,000 to $18,000
- Full insulation, drywall, and interior finish: $12,000 to $35,000
- Electrical rough-in and finish, including panel upgrade if needed: $8,000 to $20,000
- Mini-split HVAC installation: $4,000 to $9,000
- Plumbing rough-in for a bath or kitchenette: $7,000 to $16,000
- Permits, plans, and engineering: $3,000 to $8,000
Most full conversions in Orlando land between $45,000 and $130,000. The spread is wide because a studio ADU at 200 square feet is a very different job than a two-bedroom apartment at 600 square feet. We deliver a written price before any work starts, which is not a promotion or an exception. That’s how we’ve done it since Isaac Pruett founded this company in 2004. The guarantee on our work runs 365 days from the completion date, and if something isn’t right, we come back and make it right at no charge.
DIY or Call Us?
You can do a few things safely on your own: check the floor for soft spots by walking the perimeter, run a moisture meter on the wall paneling, and look at the underside for skid rot after a big rain. That gives you a realistic picture of what you’re dealing with.
What we don’t recommend is attempting a foundation lift, electrical work, or permitting on your own. Orlando’s building department requires stamped plans for any ADU conversion, and unpermitted work on a structure you’re planning to live in will cost you more when you go to sell. Electrical work on a converted shed is also genuinely dangerous if done wrong. If you want to talk through what your Tuff Shed needs, call us at (850) 920-7745. Isaac is known for giving a straight answer even when the answer is complicated.
FAQs

A properly converted Tuff Shed with a concrete foundation, vapor barrier, insulation, and a mini-split system will last 30 to 50 years in Orlando’s climate, same as a stick-built addition. A shed left as-is with no foundation work will start showing real problems in 3 to 5 years.
Yes, and we do this often. If the floor is sound and only the walls need insulation and mildew remediation, we’ll quote that as a standalone job. If the foundation has failed, there’s no point patching walls until the base is fixed. Call (850) 920-7745 and we’ll walk the structure with you before anything gets quoted.
A straightforward studio conversion takes 6 to 10 weeks once permits are in hand. A full one-bedroom ADU with plumbing and a bath usually runs 10 to 16 weeks. Permitting time through the City of Orlando or Orange County adds 2 to 6 weeks on top, depending on their current backlog.
We source everything for you. We use specification-grade products from brands we trust, including cabinetry from KraftMaid, countertops from Cambria and Silestone, and fixtures from Kohler and Moen. We don’t use big-box store knockoffs on a structure that’s supposed to last 30 years. You’ll get a written line-item list as part of your price before work starts.
