they do not require gardens to be mowed, dont grow grass as part of your permaculture.
What is your land zoned as? What can yu do on your land is something you might want to read up on. It is within the city limits, can you have animals if you want to?
bees? As part of a neighborhood, making friendly with the neighbors can keep you from a bunch of troubles. Try to make what they see look well maintained and put your messier stuff out of sight.
I have troubles myself with what I can do, I keep the permaculture to curvy areas around the
trees so looks english garden like. Although I would like to plant clover around my annual vegitables, i am aware my neighbors will simply see weeds so i choose another cover. It is a give and take world.
