How to Find if an addition is Permitted?

[Peter Chan]

Hi BP!

I'm evaluating a potential deal in San Diego and the property has a ~600 sqft addition to the house which the listing agent says may not be permitted; the agent was of no further help, didn't even offer to find out for me.

The construction of the addition itself looks good - it has insulated walls, electrical outlets every 6 feet, minimum 7' height, etc... However, the permit status of the addition may affect my funding options.

How can I find out for myself whether that addition is permitted or not?

Thanks!
