Fence height and design restrictions can vary by HOA, but typically there may be limits on how tall a fence can be (often around 6 feet for backyards and shorter for front yards), as well as guidelines on materials, colors, and styles that are acceptable to maintain a cohesive neighborhood aesthetic. You will need to consult your specific HOAs covenants, conditions, and restrictions (CC&Rs) or reach out to the HOA board for detailed requirements.
