Leander's zoning ordinance does not set a single fixed building lot-coverage percentage for all districts; instead, lot intensity is controlled through setbacks, a 50 percent landscaping/non-plant-material limit on single-family lots, and impervious-cover thresholds that trigger development review.
Leander's Composite Zoning Ordinance regulates how much of a lot can be built on primarily through setbacks, building height, and impervious-cover and landscaping rules rather than a uniform maximum lot-coverage percentage in the fence/setback chapters reviewed. The ordinance defines 'Impervious Cover' to include roads, parking areas, buildings, swimming pools, and rooftop areas, and 'Lot Coverage' appears as a development standard listed among items reviewed in planned developments. For single-family and two-family lots, the landscaping standards limit non-plant material: turfgrass is limited to one-half of the lot after subtracting impervious cover, and no more than 50 percent of the lot may consist of non-plant material - effectively constraining how much of a residential lot can be hardscaped or built upon. The site development chapter ties review triggers to impervious cover; for example, projects proposing impervious cover that exceeds 1,000 square feet are subject to development-permit provisions, and impervious cover is calculated based on portions of the plan proposed to be developed. Because lot-coverage and impervious-cover limits vary by zoning district, planned-development conditions, and drainage/floodplain rules, property owners should confirm the specific maximum for their lot with Leander Development Services rather than assuming a single citywide percentage.
Exceeding the allowed impervious cover or the 50 percent non-plant-material limit, or developing without the required site/development permit, can result in denial of approval, required redesign, drainage mitigation, and code enforcement.
