According to the 2008 National Electrical Code book (US NEC):
Section 334.10 Uses Permitted. Type NM (NM is the proper term for the brand name product Romex) cables can be used in:
(1) One- and two-family dwellings.
(2) Multifamily dwellings when built as a Type III, IV, or V construction
(3) Other structures when built as Types III, IV, and V
(4) Cable trays in Type III, IV, or V structures
[Types of building construction and occupancy classification are defined in NFPA 220-2006, Standard on Types of Building Construction]
So yes, Romex can be used in a commercial building. There are other code sections that may apply to your particular installation, if you are unfamiliar with the code book and are doing electrical work you should take a class on the NEC. An improper installation could lead to personal injury or property damage. Electrical work should only be done by a qualified person. The NEC defines a qualified person as "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."

When is it permissible to wire tie a wire to a conduit?
What kind of wire? If it's a power wire, why is the place wired with conduit? Commercial buildings must put all power wiring in conduit, so if you're planning to run romex in a commercial building, the answer would be "no", it's not permissible. If it's data wire, note that there may be some "crossover" interference if the data wire follows a power wire for very much distance. It's usually not a problem to cross a conduit and tie to it, but it's generally recommended that you not tie data cable to conduit.
What conduit is used in a residential residence with 15 amp wires?

Does 6 gauge wire need to be in a conduit if run in a finished garage along the wall and ceiling?
If you are talking about #6 building wire, it needs to have mechanical protection. This means that it has to be run in conduit. If you are talking about #6 cable set like Romex, then it only has to have mechanically protection below a five foot elevation from the garage's finished floor. If the wall that the cable set is running in is going to be finished with drywall or plywood then that is considered protected.
