A suggested on another question, call Urban Design and begin discussions with them about the process. To answer your question, I don not think it is a burden to be in a neighborhood with Historical Guidelines. It's always good to be informed, as one could not take a Row house in Cabbagetown and make it a Victorian. Each historic neighborhood has unique 'guidelines' that are specific to them. Check the link I posted on your previous Trulia question (I'm including it below for convenience sake).
Oh, as far as other neighborhoods, Ormewood Park has the same school zoning as Grant Park. Oakhurst and Kirkwood may be options to look into also.
Make sure to stop by the Grant Park Summer Shade festival this Labor Day weekend

Kirkwood? Ormewood Park?
Grant Park might trump them all, and a lot of what you seek is about one grand old house on a terrific street, right?
Michael Dryden in Grant Park, Cooper Pierce in Inman park and Tim Nichols in Poncey Highland are all superb Intown residential architects who understand old houses and the complexity of working within the Urban Design guidelines that you'll inevitably face.
Anyone doing what you are about to do is providing a wonderful service of renewal for a neighborhood - thanks and good luck!
You have made a commitment to endure all of the wonderful aspects associated with working with contractors. If it is a house that you love in a neighborhood that you adore by all means go for it!!!
Hopefully you will surround yourself with good people to facilitate. An architect will be more familiar with the design guidelines affected by an area's designation. If desin restrictions have been imposed on the area they will be better able to communicate your parameters.
Good Luck and as a resident of the City of Atlanta I solute you!
