Artículo 30.- Densificación urbana
En las zonas consideradas en el Plan de Desarrollo Urbano con Zonificación Residencial mayor a la establecida originalmente o en los proyectos de densificación urbana, es posible incrementar el número preexistente de viviendas sobre un lote. En este caso se puede hacer uso de los retiros o de las áreas libres para ubicar las circulaciones verticales de acceso a las nuevas viviendas, las mismas que deben respetar las características de la edificación y del entorno.
