A small suggestion to make Houses and Apartments different and both useful.
Limit houses to have no more than 5 or 10 homes and not allow offices, or at least not add any jobs. This would mean that houses are small and have the advantage of not costing any jobs.
Apartments could than require an office for every 10 or 15 homes, so there is a small job cost to big apartment buildings.
A limit to how many homes can be in other industries might be a good idea, if you don't want houses and apartments to be totally useless in comparison. Maybe limit them to 5 homes or something like that.
