Regulating teardown McMansions in the Boston suburbs

The town of Sharon, Massachusetts is having a classic discussion regarding teardown McMansions:

Although any architectural style can be part of the large-house phenomenon, the typical structure that draws concern has a high roof line and sits closer to the property line than the one it replaced. Whether the problem is purely aesthetic or a more practical one of blocked views and bright outdoor lighting, some people dislike a house that dwarfs the rest of the neighborhood. Call it McMansion backlash.

A few Boston-area communities, including Cohasset and Wellesley, have imposed special regulations on new houses over a certain size, and now the town of Sharon is considering doing the same…

Typical discussion. Some people want the right to sell their home to whomever wants to buy it and people should be able to do what they want with their property. Others argue that the character of neighborhoods are changing, older residents may be priced out of the neighborhood by rising property taxes, and the bigger homes are ugly or too large.

Since this is a common story, I wonder how many communities prepare for this situation beforehand. On one hand, perhaps this seems like a waste of time – if it is not a problem, why bother spending time addressing the issue? Certain communities may never really have to deal with teardowns because the property is not that valuable and the community is far away from urban areas. On the other hand, many suburbs could be in this position, particularly with calls for redevelopment and a growing interest in being closer to work or amenities. Why not have some regulations on the books before it turns into a contentious public discussion? Once things start changing and the land is so valuable that there are people willing to offer big money for older homes, it is harder to slow the process.

An added bonus of having this discussion early on would be that it could a rare moment for community members to discuss what they really want the community and its neighborhoods to look like in the future. Without these clear plans, communities tend not to discuss these things until something drastic or large pops up and then people become passionate. Planning ahead could both save some trouble and also allow residents and leaders to be proactive in setting guidelines and ideals.
