Condos are not universally bad. You wouldn't know it from the way people in Waterbury have been talking lately, but it's true. Locally, take a look at Heritage Village. That was built many decades ago, but is still high quality and very park-like, with the winding roads and dense woods.
The problem is that condos in Waterbury are almost always built with the cheapest materials and methods. They are some of the ugliest buildings you will ever see, easily considered a blight even when they are well maintained. Bradley Gardens is one of the worst and is a proven fire hazard, but it is certainly not the only example of shoddy condo construction in Waterbury.
Residents of the "nicer" neighborhoods have been complaining loudly about how they don't want condo developments, but I suspect that it's not condos in general they are opposed to, it's the slum-like condos that typically get built in Waterbury that they are resisting.
Building codes typically deal with safety issues. Aesthetics are harder to pin down and enforce. But what about enforcing a minimum ratio of built acres to landscaped acres? How about enforcing a certain number of shade trees per landscaped acres? While I'm at it, how about requiring any new building development to construct sidewalks?
I could keep going with the wish list for a while!
