“The house has a really unique and cool design”
“I was looking for a really beautiful tiny house to put on my back deck for an extra bedroom. While backyard unlimited costs more than their competitors, the house has a really unique and cool design (with 7 windows and a slanted roof going up to 11 ft), they were very prompt and friendly, they delivered it 2 to 3 weeks early, and all of the people I spoke with were extremely respectful polite and professional. I cannot recommend them enough.”

How much does it cost to build a Tiny Home in San Francisco?
Building a Tiny Home or ADU in San Francisco typically costs in the range of $300,000 to $400,000, depending on the model, customizations, and furnishings. A base model that is modestly equipped can cost about $275,000.
How do I design a Tiny Home that meets San Francisco building code?
San Francisco requires that a licensed design professional sign and stamp your Tiny Home plans, and plans must comply with common limitations that include:

- In most residential neighborhoods, you must provide private, open space
- Unit must have adequate natural light and ventilation
- Unit must meet fire safety requirements for safe entry and exit
Do I have to obtain building permits from the City of San Francisco?
No. Permits for building your San Francisco Tiny Home are included in the cost. Once plans are completed and you sign the contract, we apply for your building permits through the local planning office in San Francisco. Permit processing times vary and can take up to 16 weeks for approval from the city.
