From a insurance perspective and if you have two different addresses according to the la county records, you may be required by your lender to have two different polices for each unit. Also, remember that if you don't have a association then you may be the one responsible for the outside walls and the whole property itself. If that's the case you might want to get a habitational policy that covers both the property with the structure on it and also whatever personal property you may have. Most HOA's cover the dwelling up to the 4 walls, from the 4 walls in, it becomes your responsibility to insure your building property such as carpet, walls, plumbing, bathrooms, kitchen, Kitchen counter, cabinets, appliance and what not. Usually it's going to cost about 45.00 a sqft to replace the condo inside the 4 walls. From what it seems to me, you maybe responsible for both the inside and outside since you don't have a HOA. HOA'S usually get their own master policy to cover structures and outside property liability only.
