That is the same in my state of Wyoming. The assessors visit my property every year and ask what improvements I've made. Two weeks after I bought the property they showed up and went through a checklist with me that detailed everything they knew about the house. I did something taboo and brought them into the house because they listed something as "fair" that was "bad".
It's funny though, all of this is just for tax revenue. They don't care about electrical wiring, plumbing, etc... I am told that when a house is first built they will inspect the electrical but I do not believe them. I've had to fix dozens of incorrectly wired sockets and really janky wiring in the circuit breaker panel and missing grounding connections.
On the other hand, as a landlord it's not your health and safety you're gambling with. As long as your insurance company doesn't complain, spending a lot of money to decrease the risk of fire doesn't make financial sense.
