请教楼梯扶手不符合现在的code修不修？

4-plex，在北加。Inspection report有下面信息。请问这是必须修吗？价钱大概多少？看了好几个房子，老一些的好像都有这个问题。

如果不修，以后会不会有法律风险？例如租户受伤，被告。。。多谢！

The deck railing is too low and is a safety hazard. The California Building Code as of Jan. 1, 2008 requires minimum guard rail height at landings, porches, decks, and balconies more than 30 inches above grade to be 42 inches in vertical height. I recommend immediate correction by a licensed contractor as necessary.

The baluster spacing at the perimeter of the deck is too wide. It's possible for a small child to slip through the railing and fall. Current codes specify that baluster spacing can be no more than 4 inches wide. Even though this requirement may not have existed at the time this property was built, I consider this to be a life/safety issue, and feel it would be prudent to bring the baluster spacing up to current code. We recommend contacting a licensed contractor for repair.
