While reading an article about some big homes that are still being built in the United States (are there enough wealthy people doing this to counteract data?), there is an interesting part about the negative attention these homes can draw.

One obvious drawback of building big: unwanted attention. Neighbors sometimes chafe at the idea of an edifice down the street the size of the White House. Reacting to McMansions that went up in the housing boom, some communities, like Chevy Chase, Md., passed rules that regulate more strictly how big houses can grow, says John McIlwain, a senior resident fellow specializing in housing issues at the Urban Land Institute.

Near where Mr. Pritzker’s home is under construction, neighbors are up in arms over another of Mr. McCoy’s projects, a roughly 70,000-square-foot compound (downsized from 85,000 square feet) awaiting permitting for Prince Abdulaziz ibn Abdullah ibn Abdulaziz Al Saud, son of the king of Saudi Arabia. The compound is on three lots and would include a main home of 42,000 square feet—part of it underground—a guest house, pool cabana, gate house and another residence of up to 20,000 square feet. The prince’s lawyer, Benjamin Reznik, notes other residences in the neighborhood are super-sized and says opposition has been “fomented” by neighbor Martha Karsh, the wife of Oaktree Capital Management founder Bruce Karsh. Ms. Karsh has hired publicists to attract attention to the project, he adds. “Newt Gingrich wishes he had that campaign going,” says Mr. Reznik.

George Mihlsten, a lawyer for a community coalition and Ms. Karsh, says the coalition hired his firm and that Mr. Reznik has hired outside help too, including a community-relations firm (Mr. Reznik says that was in response to Ms. Karsh’s campaign). “He likes to focus on Martha, but the truth is he and his client have created the controversy by proposing an outlandish plan and going behind the backs of the community to try to get it built,” Mr. Mihlsten says in an email, likening the scope of the project to a small community shopping center. More than 1,500 residents of Benedict Canyon signed a petition expressing their opposition to the project as it was originally proposed, according to a representative of the coalition.

The scope of these projects makes them extremely complex to construct. Finding or assembling the property can take several years, and the design and construction of a super-size project can take up to five years or more, builders say. (These days, lower labor costs in some areas can mean quicker turnaround times or better value.) Just finding parking for the 100 to 200 tradespeople that can be on-site for a big job, compared with the eight to 20 people typically working on a 4,000-square-foot home, can require planning; commandeering church parking lots is one standby.

If you have enough money, can’t you just budget some resources for dealing with the neighbors and/or going to court to make sure your home is built? But if your neighbors are also wealthy, perhaps you are in trouble…

The article hints at the regulations that many municipalities have put in place in order to limit these large homes. This leads me to several thoughts. First, are there communities that have intentionally left no or few regulations in place in order to make it easier for the construction of bigger homes? Another way to think about this would be to look at communities that have had public discussions about regulations for larger homes but then decided to do nothing. Are there communities that actually want these larger homes? Second, are these extra-large homes extremely concentrated in a few communities that have more relaxed regulations? Third, has someone ever looked into whether the level of opposition to a proposed big house is proportionally related to the size? For example, a house that is 500 square feet larger than the surrounding homes might receive one-quarter of the NIMBY attention of a proposed house 2000 square feet larger.
