Help in making my home safer.

Assuming this is for the person for whom you are caring, as your profile states, what issues does this person have? Mobility or strength issues? Deconditioned? Stroke recovery?

Being more specific will provide more specific answers, as Eyerish states.

Are you talking about safer as in preventing falls? Or just safer in general as in installing fire alarms and things like that?

Do you use a walker?

Do you live alone?

Some more information would help in getting the answers you need.
