Green home rules by state

How to use the state directory

1. Choose the state where the property is located.
2. Open the state page and select the guide for the project or situation.
3. Read what the rule protects and which conditions apply to your property.
4. Then check the local permit office, serving utility, and property documents named by the guide.

Check the guide’s scope

Match the state, equipment, property type, and proposed location to the guide. A missing guide does not mean your project lacks legal protection.

What may still vary locally

Building and electrical permits, setbacks, historic review, fire access, utility interconnection, and the ownership or use of a roof, wall, parking space, or common area can change the next step. Open the focused guide for the source-check date and the office or document to contact.
