What is the minimum requirement for cleanliness and maintenance of rooftop gardens and landscaping?

The minimum requirement for cleanliness and maintenance of rooftop gardens and landscaping is that they must be maintained in a healthy condition. This is essential for several reasons.

First, a healthy rooftop garden ensures safety by preventing hazards such as falling debris. Regular maintenance helps to keep plants in good condition, mitigating issues such as overgrowth that can obstruct pathways or access points. Furthermore, healthy plants contribute to the overall aesthetic and environmental quality of the space, promoting biodiversity and potentially improving air quality.

In addition, a well-maintained garden can help to retain stormwater, providing additional benefits to building sustainability. Allowing a rooftop garden or landscaping to grow freely, encroach on clear areas, or neglecting special maintenance could lead to complications like water intrusion or structural damage, which could create safety concerns and additional costs. Thus, maintaining the garden in a healthy condition supports the longevity and functionality of both the landscape and the roof structure itself.
