You are still living there while the wall is open

An addition is built against a house people are still using. The scope has to say which rooms stay usable, which bathroom remains in service, and when the kitchen is down if the new work cuts into it. Dust doesn’t respect a hallway. A temporary wall at the cut is part of the job, and so is thinking about the return air so the existing system isn’t sucking the job site into the bedrooms. If the project is really one room rather than a whole wing, say that early. The tie-in problems stay. The amount of house you lose for a month can shrink.

Dust, the one bathroom, and the night the wall is open

Say which bathroom keeps working. Say which night the exterior wall is the most open, and how it gets closed before the crew leaves. A loose tarp is a sail, and a house with a hole in it is not secure. Tell your insurer an addition is underway. We cannot bind that policy. An unreported structural opening is how a claim gets argued later, and that argument is yours to lose.

Children, pets, and the only driveway

These are schedule items. The dumpster cannot sit in the only way out. A concrete truck on the morning the school bus comes is a planning failure, not bad luck. Power and water shutoffs get a day and a time, not a surprise when a line is cut. If the roof tie-in needs the house empty for a couple of days, we would rather say that at the table than on the morning the tarps go up.

Pets, kids, and a single driveway are scheduling items, not personal details. The dumpster can’t block the only way out. Power and water shutoffs get named by the day, not discovered when the plumber cuts a line. One bathroom has to keep working unless you have agreed to leave. Some additions are easier if the house is empty for the week the roof is open. We would rather say that at the kitchen table than on the morning the tarps go up.

A new slab meeting a floor that has already cured

The new slab has to meet a floor that already has a finished height. That height includes whatever is on the old slab: tile, vinyl, or a layer of leveler poured years ago. A new monolithic slab isn’t automatically the same elevation. Miss it and you get a step in a walking path, or a sloped patch that feels like a mistake. We measure the existing finish before the forms go in. The joint between new concrete and old concrete is a real joint. A smear of mortar will crack when the two slabs, poured decades apart, move differently.

Outside, the dirt still has to fall away from both slabs. An addition set even a little low becomes the place the yard drains to, and then the place the afternoon storm sits. Door thresholds at the new exterior wall are a separate height problem from the interior match. You can get the floors even and still have a door that ponds. Both numbers go on the drawing before the first form board is set.

Landing a new roof on an old wall

The new roof has to land on the old one without a valley that dumps into the wall. Underlayment on the new side has to lap under the old, which means pulling shingles back farther than the patch looks like it should. Step flashing goes in where a wall meets a slope. A kickout at the bottom of that joint sends water onto the roof instead of behind the stucco. Caulk isn’t that flashing. If you can see a bead of sealant doing the work a piece of metal should do, the tie-in isn’t done.

If the existing shingles are already tired, weaving a new roof into them means you’ll disturb that joint again soon. Replacing a tired roof while it’s already open is often the cleaner sequence. It’s a different scope and it should be priced that way, not hoped into the addition. If the old roof is sound, we open only what the lap needs and we say so. Either choice is fine. Leaving it unsaid is how the leak shows up over the existing bedroom.

Cutting block that’s still holding the house

The wall you want gone is often the wall holding the roof up. Concrete block doesn’t get a wide opening because a saw was available. It gets a lintel sized for the span, temporary shoring while the cut is open, and a look at what the original bond beam is doing. Framing the new opening in the old wall includes that lintel, the bucks, and the way the new roof ties back into the old structure. The beam depth can drop the headroom. That is a paper decision. It isn’t a surprise after the saw.

Pipes, ducts, and wires already in that wall

Wires, vents, and ducts like the wall you just decided was optional. They get moved on a drawing, not discovered with the saw. The panel may not have space for the new circuits. The air conditioner may not have capacity for the new volume. That is a load question. The fact that the house feels fine in April doesn’t answer it. Septic systems are sized from bedrooms. Add a sleeping room and you may be in a health-department conversation on top of the building permit. The parcel rules in the residential scope this addition sits inside still apply: the city if you are inside Ocala, Belleview, or Dunnellon, and Marion County Building Safety if you are not.

Keeping the rest of the house dry and lockable

When the exterior wall is open, the house isn’t secure and it isn’t weather tight. The day’s cut gets closed before the crew leaves, with something that sheds water. A loose tarp becomes a sail. You should know which night the opening is largest. Tell your insurer an addition is underway. That policy is yours, and we can’t bind it, but an unreported structural change is how a claim gets argued. A garage on that same side of the house has the same roof and slab problems, plus a fire separation. Don’t let it get drawn as more of the same addition without that wall assembly.

New stucco next to old stucco won’t disappear. The texture can come close, and the paint can be matched on a sample, and the new work will still weather on its own for a while. Interior base, flooring at the joint, and whether the whole existing wall gets repainted belong in the scope. We would rather set that expectation on a sample board than promise an invisible patch. The addition can be built well and still show a line where it started. That line is honest. A cracked fake joint isn’t.

The cost variables, without a square-foot price, are on home addition cost. Whether the office is the city or the county is on home addition permits. The service page you are on is the scope. The guides are the questions to settle first.

The old house does not stop being a structure

Shoring, the bond beam, and the headroom you give up

The wall you want gone is often the wall holding the roof. Block does not get a wide opening because a saw was on the truck. It gets a lintel sized for the span, temporary shoring while the cut is open, and a look at what the bond beam is already doing. Beam depth drops the head of the opening. That is a paper decision. If the beam lands in the middle of where you pictured a transom, you find out before the saw, or you live with a shorter door than the drawing promised.

Wires and ducts are already living in that wall

They get moved on a drawing. The panel may not have a spare space for the new circuits. The air conditioner may not have capacity for the new volume, and the fact that the house feels fine in April does not answer that. Septic systems are sized from bedrooms. Add a sleeping room and you may be in a health-department conversation on top of the building permit. City of Ocala, Belleview, and Dunnellon review inside their limits. Everywhere else in this county is Marion County Building Safety. The mailing address does not cast the vote.

Matching the old finish without lying about it

New stucco next to old stucco will show a line for a while. The texture can come close. The paint can be matched on a sample. The new work still weathers on its own. Interior flooring at the joint, and whether the whole existing wall gets repainted, belong in the scope. We would rather set that on a sample than promise an invisible patch. A well-built addition can still show where it started. A cracked fake joint is worse.

Before a price means anything, someone has to say how old the roof is and whether the addition is adding a bedroom the septic was never sized for. A tired shingle roof that we tie into will be opened again the next time that roof is replaced. Pricing the tie-in as if the shingles have another decade is how the leak shows up over the existing bedroom. If the roof should be replaced while it is already open, that is a separate scope. It can be the right sequence. It should not be a surprise stuffed into the addition after the shingles are already pulled back. The same honesty applies to the floor. Measure the finish you walk on, tile included, before the forms are set. A step you did not draw is a step you will trip on every morning, and no transition strip hides an inch. We measure that floor. We do not eyeball it from the doorway.

The company on the permit

Ocala Building Contractor is a disabled veteran-owned business with 27+ years of construction experience, licensed in Florida as certified building contractor CBC1263067. We write the occupied-house sequence into the scope because that is the job, not a courtesy. Call (352) 820-6068 with the property address and which side of the house you want to grow. The office is at 217 SE 1st Ave Ste 200 – 18, Ocala, FL 34471. If the work is really one sleeping room, the egress rules on the room-addition page are the ones that will fail you. If it is a garage, the slab has to slope and the wall has to separate the car from the house. Do not let either of those get drawn as “more of the same addition.”
