HELP. Nashville occupancy limits

[Elijah Jay Dangerfield]

First: thank you for reading this. I’ve run into quite the problem. I got a house under contract with the intention to house hack it. It has 4 bedrooms now but I intend to finish an addition on the house and add more bedrooms. There’s only one problem: Davidson county (Tennessee) doesn’t allow for more than 3 unrelated persons in a single dwelling. Their codes language on “related” is pretty tight too. Trying to get it rezoned would get me to 6 bedrooms at best and even then won’t cover every bedroom I would like to rent. What should I do? Is there any way around this ? Is it a big deal?
