Texas rental questions

[Anil Rathi]

I am renting out a single story single family home in Texas.

1) do I need just 1 carbon monoxide detector (I already have multiple smoke detectors)

2) house was built in 1977, i’m not aware whether it has a lead paint or not, is there anything else I need to do other than providing the rentee the pamphlet on the lead related issue?

3) What do I have to do to make sure house meets the disability requirement?

Appreciate any help.
