Deed Restrictions- How to verify what can be build

So I am looking at a lot and it has deed restrictions. NO HOA. The area is old neighborhood. Restrictions are such as if you face the main street only commercial can be done and if you face other residential is allowed. All plans to be approved by commitee or survivors etc.

How do I go around what can be done and what can not be done? Are their  services I need to hire who can understand the restrictions? Will the city help me to understand if I propose them  a plan?
