"What wiring methods do you use inside?? IS everything surface mounted?"
Walrus, the older ones are wired with BX channelled into the mud then patched over. If they were build before about 1930 they usually have K & T in the attic and BX added later. Some have firred walls. For new construction we are allowed to use UF cable in the mud or joints. Usually only the outside walls are adobe, so interior wiring is inside the partition walls. The structures that still exist from the 1800's have all the walls made of mud, built with no electricity or running water. I've seen lots of "creative" methods used to bring electricity into these structures.
