I have been under the impression the typical fire separation wall in residential construction, single family was 5/8 "firecode" on the garage side. As a matter of fact, to comply to a resale inspection, I had to rock this certain "illegal" laundry room in a garage, overlaying the existing 1/2"...
Because this garage is over 1,000 SF it falls outside the scope of a "private garage" and is, for code purposes, a "public garage". Section 311.3 Classifies "Parking garages, open or enclosed" as a group S-2 Occupancy. Because the Business Occupancy is a hazard to the S-2 occupancy, a fire barrier wall must be constructed between the two.
Does the residential code require that the garage slab be lower than the house floor? I couldn't find it anywhere, but I have a contractor who swears it does.
I have a single car garage with a sectional overhead door, I have space on one stucco wall for a 24 x 75 pedestrian door. will that size be acceptable since it is not the main egress door?
The house was designed with 8′ foundation walls, and had a rise from the garage floor to the subfloor of 17-1/2″: 4″ for vapors + 1-1/2″ sill+ 11-1/4″ joist + 3/4″ sublfoor. For multiple reasons (steps, topography, fill and grading) I would like to lower the living area and entry to have only one step up from the garage.

If the garage is located beneath any habitable space, the separation requirements are more stringent, necessitating the use of 5/8-inch (15.9 mm) Type X gypsum board or a material that offers equivalent protection.
