What does a 1,200 sq ft house include?
A 1,200 sq ft house usually has 2 to 3 bedrooms and 1 to 2 bathrooms, a footprint of about 30 × 40 ft as a single-story ranch. It is a popular size for starter homes, retirement homes and ADUs on larger lots.
Why does a 1,200 sq ft house cost more per square foot?
Small houses cost more per square foot because the kitchen, bathrooms, furnace, water heater and permit fees cost almost the same whether the home is 1,200 or 2,000 sq ft. Those fixed costs are spread over fewer square feet, so expect the upper half of your state’s range.
How can you cut the cost of a 1,200 sq ft house?
Keep it to one simple rectangle under a gable roof, choose one full bath plus a half bath, and use builder-grade finishes. A modular or barndominium build can bring the total well under $200,000 in many states. More ideas: cheapest way to build a house.
