See question 3771 above regarding that a shul should be higher than the roofs of the city where people live. How do we define a “city” as far as this din is concerned, does it mean the whole city?

Horav Shlomo Miller’s Shlit’a opinion is that in our days when it is practically impossible to comply with this mitzva comparing to the whole city, one may at least comply by having the shul be higher that the rest of the houses in that particular block. The Rov added that the above may be correct even for just the next neighboring houses.
