I would go with 16 inch centers. The reason is that building inspectors tend to be anal retentive at times. As for the shelves, you can use pieces cut 14 inches wide from a sheet of Baltic Birch. Cut notches in using a saber saw (jig saw) to fit around the 2x8 studs. A sleeper or fat block between the studs can be used to support the shelf with screws through the BB and into the fat block.
These days the county assessors use Google aerial photos to "discover" new buildings. County Assessors also respond discretely to anonymous phone "tips" from irritated neighbors.
I had, what I believe was, a Contractors License Board enforcement officer show up asking me to build cabinets for him. He was too generically (Kaki and short sleeve dress shirt, no tie.) dressed to be a possible customer and was very irritated that I told him that I couldn't because I wasn't a licensed contractor. As he drove away I noticed that his license plates were "Exempt" meaning that he was from a government agency. Obviously a neighbor didn't think that I should be building cabinets for my garage.
