Just something to consider, Here in Southern WV, we had some issues using the world "toilet" once, I switched up the language to Composter, or Comfort Station, the issues seem to not be an issue anymore. Legal wording for the county and the state can someone be very important.
I build Vermiculture Compositing Stations. ( We use worms to eat your poop) Learnt the build from Africa and some nonprofits. We have a few in the state parks here in SWV
I pursued a variance to install a composting toilet with a reduced capacity septic tank and drain field and got shot down. Texas has short list of approved composting toilets that all cost $2000+. Then, even with a composting toilet I would still be required to have a minimum septic tank size of 750 gallons and drain field that could handle the typical waste water flow of 60 gallons per person per a day. Because my cabin's water supply is entirely from rain water we were able to get the drain field down to where it only has to accommodate 40 gallons per person per a day.
I'm in the middle of the process now(I just received the okay to be began construction Friday) but I'll plan to make everything to specifications for inspection and then put in my bucket composting toilet.
