Im tired of looking for a stud every time I want to fasten something to the
wall in my garage and being limited by the position I can put it. I want to
sheath one wall, maybe two in plywood on the inside It has been suggested to
me that ths may be against code and be a fire hazard. I dont see how as the
wall will still be covered in 5/8 drywall. I havent been able to get a
response from local city authorites on this. Any info would be greatly
appreciated.

Building codes usually call for a 5/8" covering of drywall or fire rated
material. On top of that, we, as a society of homeowners, put paneling,
pegboard, paper covering, all sorts of decorative material. drapes, etc.

My garage is detached. I insulated it, put up drywall, but in some areas I
put plywood or pegboard over the drywall for the convenience of hanging. I
don't give a damn about codes, it works. I don't see it as a safety issue
but I take normal precaution of electrical, tools, liquids etc. That, IMO,
is a far greater danger than a piece of plywood to hang tools.

The code requirement that I know of is a fire separation between house
and garage.
That leaves the other wall free for what ever you want.

As Palowski notes, real world arrangements includes all kinds of
flammable materials.

Oh, by the way: If you want a cheaper way out, you could just
run ledger-board the whole length of that wall at two or three
heights. If you put a back-bevel or ship-lap along the to edge,
you can even hang things like cabinets that way.

As long as you cover it with a fire-rated depth of sheetrock, you
should be fine. It used to be that if you had 3/4" of wood,
you didn't need sheetrock at all, but I don't know if that's
still the case. (In a single dwelling unit, that is.)

If the ultimate wall surface is 5/8" firecode drywall it will not make
any difference fire rating wise if there is a layer of plywood between
the drywall and the wall studs (other than the increased cost). The
drywall provides the fire rated protection for the plywood just as it
does for the studs.

Wrong, put the plywood behind the type X drywall. You maintain the fire
rating and the ability to attach shelving or whatever at any point.
There is nothing to be gained by putting the plywood as the exposed
surface and you loose fire rating.

With plywood on the exposed side, it can be ignited readily since it has
no fire protection and it then provides a fuel source that could burn
long / intense enough to defeat the rating of the type X drywall behind
it and ignite the studs or rafters on the other side. With the plywood
behind the sheet of drywall the plywood receives the full protection of
the drywall.

Why would he lose the fire rating if his wall assembly, (5/8" drywall on
both sides of studs), is still intact?

By putting a large quantity of unprotected fuel in direct contact with
the rated wall?
