Simple Answer: Yes, Frederick Maryland is Good place to live for these reasons and many more:
As a person who grew up in a and around Washington DC, moving out to the spacious and open air areas of Frederick was refreshing. It’s a small town feel with suburban comforts and “southern decency.” There have been plenty of times where I have had a flat or dead battery and a stranger has randomly offered help. People still hold doors for you if they see you coming and you are likely to get a smile and good morning as you walk or run for some early morning exercise.
Frederick is an excellent place to retire because it’s smallish town vibe with plenty of creative and retirement friendly events and amenities. However, it does get pretty cold in the winter. Not like New England cold, but every few years you will get a healthy foot or so of snow or be snowed in for a day or two. Another good thing is that there’s plenty of golf course near and within 10-15 miles of Frederick, so you have your choice of tee time.
Frederick Maryland is a relatively as safe place to live. You can check crime reports sites and compare the theft violent crimes Frederick to most Metropolitan cities and you will see that Frederick wins. However like most cities Frederick has areas that are “safer” than others. The best thing to do is to look at the crime report stats.
Frederick is definitely dog-friendly. There are plenty of dog-friendly parks and paths for your dog to run and get exercise. There are a lot of pet owner events and groups. You can find more pet friendly events by check out meetups.
