 The zoning system in the Philippines is explained in the Zoning Ordinance laid out by the Housing and Land Use Regulatory Board (HLURB), and the cities and municipalities are responsible for regulating land use through ordinances created by each local government unit.The Philippine zoning system is divided into 11 types based on density and usage, and emphasizes the most suitable use and orderliness of the community.Definition of each density may differ between the ordinances of the local government units concerned, so one municipality may define a light density residential zone to allow 4-storey buildings, while another may only permit 2-storey buildings.
