Non permitted for your own use you just may have to demo when you sell. 

@Frank Yang Thanks so much for your help.

Good luck. https://www.census.gov/data/tables/2017/demo/popes...

When we demo'ed the basement we found that there was essentially no foundation and the best option would be to demo the house and build a new, modern and larger SFR/ADU.We decided to proceed with the DADU constrution which when sold would pay off the loan. 

The noise level will depend on what training activity occurs at the base (i.e. airfield, demo range, etc). 

I'm currently demoing Podio and Monday.com, both of which could work but neither seems to check all the boxes. 

@Kevin Christensen be eachothers yin and yang .

Had a lot of back and forth due to FEMA regulations and that we’re not supposed to “overdo it” beyond 50% of the assessed value, otherwise, we need to demo it.We hired a private appraiser to increase the value of the property, and we sort of got away with it.

Home much does it cost to demo a kitchen? 

Also, I would have a draw schedule in your agreement with specific project milestones (demo, electrical, drywall install, finish work, etc..) and payments along with milestones rather than dates.
