Home improvements are a funny thing. Some of them have a return on investment and some do not. Here is a list from the California Association of Realtors of home improvement projects that have some pay back. A word of advise with any project you do: If it needs a permit, get one!!! It may save you a little money at the time but when you go to sell your home, unpermitted things are never good and could end up costing you much more to resolve.
