A tiny home costs $150 to $250 per square foot for a prefabricated tiny house and up to $450 per square foot for a custom-built tiny home. On average, most tiny homes are around 100 to 300 square feet and cost $30,000 to $70,000 including materials and labor. Factors affecting overall tiny home costs include size, customization extent, foundation type, appliances, bathrooms, luxury finishes, and whether the home is built DIY versus professionally.
Part of what enables tiny houses to be affordable for more people is their small footprint requiring fewer materials, allowing faster build times with lower labor costs. Tiny homebuyers prioritizing budget aim for a price per foot under $250 and use more affordable materials and standard finishes.
