Time for another option for smaller buildings? Building a crawl space foundation in a backyard for an ADU can be an expensive, time consuming and messy project.
Instead of just a slab or a crawl space it might be time for an alternative. GoliathTech is one option and DiamondPier is another. Both systems have ICC-ES reports.
