Ground Mount Notes

Ground Mounts: Fencing requirements will be based on city jurisdiction rules. If in a park, no more than 75% of the lot can be covered with the mobile home and all accessory structures. When demonstrating the path of the trenching, use a dark color. Light greys do not show up when printed and the AHJ will reject the plans for it being missing.
