And there are companies out there to help you send one mail out for $0.4-$0.5 and all you have to do is give them the parameters (zip code, city, etc.).

So if you look at the map and use the umbrella zoning color codes to know at a glance if something is residential, commercial, etc and then begin to zoom in, then you'll eventually be able to view specifics like R-1, R-2, CEIR, etc. 

I used a python code to help get some of this data which is also linked in there as well.

The only times I exceeded that benchmark was when I chose to spend more on high end materials or layout changes (to bring Kitchen or BA up to code).

Code violations are expensive to fix and will be used against you.

Assuming you are inquiring for the Myrtle Beach market, the average (across the 5 submarkets and all property types) is for 72.5% to require 2 nights or less (46.5% have no requirement).This is highly variable by ZIP code and property size/type, however.

You might want to check out the local Zone Code first.

Apparently the inspection for my zip code is due like right now.

For example in and around DC some jurisdictions charge insane fees for new builds ($40k school impact fee) and have very challenging code requirements (sprinkler systems in homes..)Anything crazy like that?

For example, my electrician walked through a house I'm closing on today a few days ago to see what was needed to get the electric up to code.
