Most 3 bedroom homes are 1,400 to 2,000 sq ft with 2 bathrooms, although a compact design can fit three bedrooms into about 1,200 sq ft.
| 3 bedroom size | US median cost ($166/sq ft) | State range |
|---|---|---|
| 1,200 sq ft (compact) | $199,200 | $172,200–$258,600 |
| 1,400 sq ft | $232,400 | $200,900–$301,700 |
| 1,700 sq ft | $282,200 | $244,000–$366,400 |
| 2,000 sq ft | $332,000 | $287,000–$431,000 |
How many bathrooms should a 3 bedroom house have?
Two bathrooms is standard: a primary bath and a shared hall bath. Each extra full bathroom adds roughly $20,000 to $35,000 in plumbing, fixtures and tile at typical finishes, so the bath count is one of the easiest ways to control cost.
One story or two for a 3 bedroom house?
A single-story 3 bedroom ranch is the most popular layout but costs a little more per square foot, because it needs a bigger foundation and roof. A two-story plan puts the bedrooms upstairs and saves roughly 5–8% per square foot.
What else does a 3 bedroom house cost?
Add land, about $15,000–$20,000 in permits and fees, a two-car garage ($25,000–$40,000) and a 10% contingency. Rural lots may need a well and septic system.
