Demo

What it is

Demo is demolition — tearing out the old stuff so the new stuff has somewhere to go. On most rehabs it’s the first visible job after cleanout and the first task in Phase 1 of the Larossa System, which Ross calls Tabula Rasa (Latin for blank slate). Phase 1 covers demo, structural repair, and stop-the-bleeding work.

Scope of demo depends entirely on flip type. A cosmetic flip might just be a kitchen and one bath tear-out. A renovation pulls flooring, cabinets, maybe knocks down a wall. A full gut goes to the studs. The rule across all of them: demo only what you need to.

Why it matters

The trap is what Ross calls new-builder-itis: the impulse to rip everything out because it looks cleaner when everything’s gone. That impulse costs money. An outlet kept is an outlet you don’t rewire. A cabinet kept is a cabinet you don’t replace. A wall kept is a wall you don’t reframe.

More important: grandfathering. This is a foundational principle. What was built to code when it was built is legal today — until you touch it. The moment you open a wall, every system behind it gets exposed to current code. Wiring that was legal in 1972 is now a violation. Plumbing that was legal in 1985 is now a violation. Ross in the nightmares video: “There are other issues that make a house dead on arrival… I bought a house before that came with an extra lot…” That same video covers what happens when you disturb asbestos-containing materials — “the EPA came and gave him a huge fine” — which is why encapsulate-don’t-remove is the correct move when possible.

The other reason demo matters: it’s where surprises live. Pull up carpet and find rotted subfloor. Open a wall and find knob-and-tube. Remove a tile surround and find black mold. You can budget for demo itself. You can’t fully budget for what demo reveals. That’s why every flip needs a real contingency line item in the budget before work starts.

There’s also a sequencing law, not a preference. Demo happens before MEP rough-in, before drywall, before insulation. Inspectors need to see wires, pipes, and ducts exposed before walls close. Demo does not happen before cleanout. Trying to demo a trashed house without clearing it first means the crew is fighting through junk and garbage, and their bid reflects it.

How it shows up

Scope-limiting demo is a discipline. Ross’s phrase: “Don’t take down the drywall.” Leave the wall alone and grandfathering protects what’s behind it. Open the wall voluntarily and the inspector can require current-code wiring, insulation, fire-blocking, and sometimes structural upgrades.

The exception: when the wall conceals a known problem. Active leak, pest damage, pro diy work, galvanized pipes that need re-piping. Then you open it because you have to — not because you want a cleaner slate. Even then, open the minimum. Make a square cutout, not a tear.

Demo is the first job in Phase 1’s Tabula Rasa block. It’s followed by framing repair, plumbing rough-in, electrical rough-in, hvac rough-in, the Gauntlet inspections, then drywall and finish work. If demo bleeds into later phases because you kept finding things, the whole schedule slips.
