There May Be Community Rules About Landscaping.
You can always do whatever you want with your yard, especially regarding your front yard. Most new communities have rules about what the outside of homes should look like, which extends to landscaping. For example, you could only create a garden with part of your front yard. Regulations governing the kinds of trees you grow, or the size of your shrubs could be a less drastic example. Check community guidelines to find out what is prohibited in your neighborhood.
