How do you keep non-pilots from buying on airpark?

How do airparks discourage non-aviation individuals from buying lots or houses on residential airports? Several of the property owners at our residential airport are concerned about this. We don’t want to slowly lose control of our airpark.

This is a good question that comes from an airpark resident. It’s not the first time we’ve been asked the question and it probably won’t be the last time.

Does anyone have a good answer? It comes up regularly at airparks so if your fly-in community has successfully dealt with this situation, let us hear from you.
