Hi wildlifr,
So, I am newer to the industry and drone regulations, but I am aware of a couple important things you might consider:
1.) resident-public can ask to get a "no-fly" area or indicator over their property (like on Airmaps), similar to what you would see from other areas such as airports. This is not legally binding, and if pursued by the landowner, they may lose in court. In other words, there are no (current) laws of "flying over" (especially in our great state of WA. These indicators are used to help responsible drone owners to avoid these areas as much as possible...like schools. So if you see one, just be a solid person and show some respect. If someone is complaining try to communicate what you are doing to alleviate worry. That being said you must be careful to not invade privacy ... i.e. - hovering above someone's window or property with intent to 'survey" or "spy". (your flight data can prove or disprove if you do this) Our neighboring state of Idaho has passed special legislation to define spying or surveilling, but they as well as WA, have pretty free and open drone laws (except Seattle area parks).
2.) There are tons of places to find local and state laws, but Sarah Nillson has a website that is chocked full of the most valuable drone information known to man...(maybe a bit of an over exaggeration)

here is a link to her website and the Washington Laws.

Hope this helps!
