Property taxes to rise commensurately.
I assume many of these don’t accommodate children (at least smaller models); here in NJ 2/3 of our property taxes go to the public schools, so municipalities like new housing that doesn’t accommodate children - few people have use for the 100+ year-old housing stock built as single-family homes with 4-5 bedrooms. Many of the existing ones are re-purposed to 2-family homes (with or without permits), or if they are old enough, demolished and replaced with a new multi-family.
Makes parking a nightmare...
