A lot of your answers are coming from Realtors outside of your area and Realtors are not builders. We can quote average sq ft price for resale, but in the Heights, that is even difficult with out knowing the home.
For you Realtors out there that are trying to figure out what I am saying , the Heights has homes built from the turn of the century( the last one) to today. Some of the homes have been restored some have not. Some of the homes are large some are not.
Melinda we do not even know if your addition will be contemporary, Victorian, high ceilings , a bath, a kitchen, all of this has a lot to do with the rice of the addition. A sleeping porch vs a bath room ?
A little more information and I can forward to some builders and hope they answer.
Not quite comparable to new construction cost in the MLS as the cost of the property is included there and your property is already obtained and very high.
Hoe we can get some builder to assist
