There are various regulations relating to the design and construction of buildings and land use. The Ministry of Construction and Public Infrastructure monitors the implementation of the building code and carries out the registration of professionals in the construction sector including engineers and designers. The Ministry of Housing and Urban Development issues and monitors the building permits, which specifies building heights, ventilation and other building requirements. Presently there are 40 to 50 construction firms who take up construction related projects in the Maldives. The Construction Sector Council brings the government and private operators together in order to ensure that the best services are delivered. Recent years have seen a rapid growth in the Construction Sector in response to the expansion in the tourism industry and increased demand for housing. The massive development programme in Hulhumale is an example of the critical role that will be played by the Construction Sector.
