We went around 10 am and somehow had the whole place to ourselves. (Minus anyone who works there) The free self guided tour is available with a talking device you can put up to your ear to help guide you along. (You get these in the middle of the building in the office to the left-free) You are also able to use your phone to listen through it if you choose. There is a QR code in the middle near the front doors after you walk in. It gives you a lot of interesting information about the numerous paintings, statues, and items stretched across 2 floors as well as allowing you to see the different rooms.(one of which was the representative hall) I did feel that sometimes the audio went off on tangents unrelated to the area it was for. It is handicap accessible and has an elevator up to the second floor. It also looked like there was also a cafeteria on the 2nd floor available for us to eat at but we didn't eat there or look into it further. We spent about an hour here but depending on how long you like to spend at each area, I'd say between 1-2.5 hours to visit the state house. We parked on the street with meters but I'm not sure if there's a parking lot available as well. Overall, it was really interesting, the building itself is beautiful, there are tons of paintings, and the audio about the outside is well worth a listen!
