Is there a code that a house of a certain size needs to be equipped with a certain type of electrical service?

Looking at a new house whose standard service is 100 amps. In order to upgrade any electric in the house - multiple high hats, electric ovens, christmas lights, pool, the home will certianly require more powerful service like 150 or 200a service.

Is this the builders or purchasers responsibility on a home this size?

general lighting, 3 volt/amps per sq ft 3400 3 is 10200 va ,is 42.5 amps, you have to add all your appliance loads, heat or ac, the largest of the two. when you add in all the factors you will need at the least 150 service . see art 220, for calcalations examples

If you had gas appliances and heat are you sure it would calculate to 150 amp minimum? I think what is most important in this situation is that the NEC is not a design manual, and its minimum requirements do not always provide an adequate installation, only one esentially free of hazards. The extra cost of the larger service in a house of that size would be quickly amortized. Install a 200 amp minimum service.
