If I rent just the storage& parking units owned by a LLC,& NOT the apartment I live in,can I report just this income?MUST/CAN I depreciate just the storage&parking units?

I am sole member of the LLC that owns the apartment I live in, the storage unit, and the parking unit; and the purchase agreement had separate prices for each item, and I am wondering if I can depreciate just the storage and parking unit prices if I rent out just the storage and parking units and I'm allowed to declare just rent from these two sources. I also wonder if I can choose to not depreciate the price of the the storage and parking units, and rather just depreciate the entire price of the apartment, storage, parking at a later date if and when I rent out the apartment in the future? I believe a downside is that the depreciation I was allowed on the storage and parking units, would still be deducted from the purchase price, which would increase my gain upon any future sale and hence capital gains tax (the depreciation recapture). But, if I don't plan to sell the apartment for many future (eg 30) years, then can I just start claiming depreciation on the entire apartment, storage, and parking LATER if I rent out the whole apartment, and would this be the cleanest way?
