Hi Tee - actually, yes, growing veggies in the front yard was banned up until 2 years ago. Someone in the northern part of Sacramento filed a complaint against a neighbor who was growing tomatoes in the front, and the gardener counter-complained and got the city council to reconsider the ban. Now, the only stipulation is that the vegetation (of any kind) is kept "neat."
This area of the front yard got sun most of the day, and was the perfect vegetable garden spot. I do have a few flowers intermingled here and there to give it some color. The area of the front yard where I have crape myrtle roots, I can only plant perennials and shallow rooted ground covers. But, 100% of my lawn is gone.
