What’s the Cost of Converting a 330-350 Sq Ft Garage into an ADU/JADU?

[Jacky Peng]

Hi Bigger Pockets Community,

I recently decided to start a JADU project (330 sq ft) using my garage. The first quotation I received from my contractor is $90,000 ($273/sq ft), or $100,000 ($303/sq ft) if additional foundation work is required. The quote includes the HVAC machine and installation. I’d appreciate your thoughts on this quote, and any suggestions or advice would be welcome.

Thank you, 

Jacky
