Are there any halachic obligations to consider the averse effects that building a shul may have on Jewish neighbors? This may include things like lowering property value, noise and other disturbances, parking etc.
I haven't, yet, located any articles or sources that address this issue directly. However, there is a general rule that "The law of the land is law" - of course hwen the local or gov. law doesn't directly contradict halacha.
Many townships / municipalities have already instituted certain laws that are geared to considering enighbors and maintaining a semblance of neighborly "peace". In my town, a shul being built must follow these rules:
The building structure must not exceed a certain height. This is to preserve the beauty of the neighborhood. One shul in my neighborhood was built to tall, and they did not receive a building permit until they redesigned the shul.
A new shul must provide a minimum number of parking spaces so that people don't park their cars on the side streets during Shabbat and Yom Tov. BTW - This is a HUGE problem in numerous communities, and during a Town Hall meeting, this along with the Eiruv issue are the 2 reasons many people vote against a shul (besides anti Semitism, which has its own problems.)
Since I mentioned Eruv, this is a "causal" problem to building a shul. Many neighbors are anti-Eruv. One of the reasons mentioned is that they don't want people walking in the middle of the road on Shabbat "hogging" the roads. I agree with the neighbors. If you want the shul built, you need to convince the neighbors that you will behave properly and walk on the sidewalks where there is one or avoid hogging the road.
- Many shuls in my neighborhood do not allow any form of alcohol which includes wine. Correct! Kiddush is either not made in shul at all, or it is made on grape juice. Certainly, there is no schnapps in the shul anywhere. The reason? Kids got drunk and some of them got loud and rowdy and a few vandalized some cars. Neighbors complained, the kids were arrested. Point being - yes, parents should have been responsible to discipline the kids long before they got an arrest record. But, if the parents won't the shul and or community needs to take over. This policy has worked extremely well.
I've mentioned some of the concerns that I believe are all valid. No doubt, there are others. Overall, yes, I do think that you NEED to consider your neighbors a lot when building the shul. In the end, it will be a huge help.
