Maybe one more Nevada vs. California comparison:
A few years ago, we built a luxury residence in Nevada, over 5,000 sq ft. Brand new construction-- building permit cost was $3,100.
I am currently considering whether or not to build a 1,200 sq ft residence in California. Less than 25% of the size of our Nevada home. Building permit cost in CA is $16,000, which is a "bargain" since it is an "ADU" onto an existing property (accessory dwelling unit.) Common term used here is a granny flat.
Had we considered building the same luxury residence in CA, the base building permit cost would be $40,000-- before they started adding requirements to improve local access roads, etc. I did not get too far in the process but estimated the administrative and permitting costs, all in, would be nearly $200,000.
The fees are ... what they are ... my reason for leaving CA was how that money is then used ... which involved spending it in ways that I do not agree with.
