The price of construction matters considerably whether you're planning on building mass market apartments or condominiums. Most cities have explicitly different building codes based on the intended use of the dwellings, interestingly most of the time to avoid civil litigation with the city. Condos generally have much higher quality duct-work / fresh air exchange not to mention thicker walls, more sound dampening etc. All of this is more expensive, but the cost is passed onto the buyer and ensures the contractor isn't on the hook for tenants levying lawsuits against the architect / contractor / city that conducted inspections.
