Our neighborhood is experiencing radical changes right now. We have a double lot (which isn't saying much... lots are 25 x 130) and our house sits on both lots. However, most all the bungalows are being bulldozed or moved off the lots around us and they're taking each 25 foot lot and putting in a skinny shotgun 2 story house in its place with no yard and 36 inches on each side to uphold the building setback requirements. This makes for a 19 foot wide home that is 100 feet deep.
The crackhouse apartments are across the freeway now. The drug dealers used to rent (or squat) here in the Houston Heights for a long time because the owners of all the homes moved to the suburbs and rented cheap to illegal aliens and trashy people. Then a bunch of us smart people starting buying houses and fixing them up in the 80's because it was so close to downtown and so cheap!
So, the cranked up drug addicts come down late at night and try to break into our homes while we're asleep inside. It's happened two times to my new neighbors living in those skinny, poorly built freestanding townhomes. I pity the fool who tries this on me. I'm locked and loaded.
