Unless you have some really good data to back this, I don't see anyway this is true.
I know in the construction industry complying with government regulations, and that is not including the industry regulations, accounts for 30-40% of the final cost of a building.
Government regulations a costly barrier to home construction.
note this report doesn't even cover ALL the costs, which is where the 10% comes from.
I see their regulations adding SOME value, but I don't see it getting anywhere close to 30%.
and the above regulation was just for residential units, single family and multifamily. those are the CHEAPEST ones to comply with.
