Bayawan City is subdivided into three development zones: The urban area constitutes only 2.3% (15.73 km2) of the city's total area and contains the main institutional, commercial and central business district of the city. It functions as the main economic hub, while economic growth nodes are established in strategically located barangays in the hinterlands. The sub-urban area is about 14.7% (102.6 km2) of the total area and is set to contain the agro-industrial zones, industrial zones and human settlements. The existing industrial activity (lime plant), the establishment of saw mills, and the identified industrial zones in the area show the natural pattern of development. Residential zones are considered in the sub-urban area to provide settlements for the people in the commercial center and in the industrial zones.
