Altadena Flooring, Drywall & Interior Finishes
Altadena drywall and floor repairs after smoke or water, permitted through Los Angeles County, with each opened wall ready for the county inspector.
Los Angeles County Public Works, Building and Safety issues permits for unincorporated Altadena, and its inspector wants to see a wall while it is still open whenever a permitted repair takes board off the studs. Replaced framing, new circuits and insulation are checked at that stage, before fresh gypsum hides them. Fire hazard maps take in sections of Altadena, so a mapped lot may need ember-resistant materials if the job reaches the exterior too.
What the county checks before board goes up
Rough framing, plumbing and electrical are signed off first, then insulation. Where the board belongs to a rated assembly, such as the Type X ceiling of a garage with a bedroom above, the inspector may also look at the fastening before the joints are taped: the right panel, screws at the spacing its listing gives, and no unprotected cut through it. Any duct crossing out of the garage toward living space has to be sheet steel. Lightly sooted board that stays in place is cleaned and primed, and with no board removed, that wall needs no cover inspection.
Floors after the walls are finished
New flooring goes down only after joint compound has been smoothed and the walls painted, because fine dust and primer drips settle into a fresh finish. Plywood subfloor that firefighting water or a leak reached is probed for soft spots and delamination, and soaked sheets are replaced. A slab gets its soot scrubbed off, since residue can stop thinset and adhesive from bonding, and then a moisture reading. Where the garage connects to the house, the new floor height is set so the connecting door still swings freely and closes on its own.

Flooring, Drywall & Interior Finishes in Altadena: common questions
The smell decides. Soot that wipes off a painted surface and leaves no smell can be cleaned and primed over, and that wall stays closed. Board that keeps smelling after cleaning, along with the insulation behind it, is removed, and the open wall waits for the county inspection before new gypsum goes up.
On the ceiling of an attached garage with living space above it, where 5/8 inch Type X is the minimum. Walls the house shares with the garage are fine with regular gypsum at 1/2 inch on the garage face. Elsewhere in a single-family Altadena house the code does not ask for it, though it can be used by choice.
Once soot is off and the concrete has been tested for moisture, the reading steers the choice. Porcelain tile tolerates more vapor than the others, glued engineered wood wants the driest concrete, and rigid-core vinyl laid floating over a barrier rides over minor dips. Any crack in the slab is checked for movement before tile covers it.
