The cost of a tiny house can range from $20,000 to $250,000, depending on factors like size, materials, foundation and whether it’s DIY or professionally built. When considering the value or cost of a tiny house, think about these things:

• A tiny house trailer is a more expensive foundation than a tiny house on skids/frame base and the type of foundation also changes the legal classification of tiny house as a vehicle or a building. See FAQs on tiny house regulations.
• Timber or steel framed tiny houses are more expensive than a plastic fold-out product.
• Well-finished tiny houses with fine carpentry are more expensive than rough work.
• Off-grid appliances and capabilities usually add an additional $20k to a tiny house value/cost, so a composting toilet is more expensive than a standard flushing toilet; solar pannels and batteries are more expensive than a plug-in-to-mains-power option and the appliances that a suitable for off-grid power sources are more expensive than standard, off the shelf appliances.
