The secretary of state for infrastructure, transport and housing (SEITV) is a high-ranking official of the Ministry of Development of the Government of Spain.

The secretary of state is responsible for planning and proposing the ministry policy on transport infrastructure and for defining, proposing and carrying out the ministry policy on land, maritime and air transport of nation-wide competence, as well as those related to port and airport transport infrastructures through its dependent bodies, public enterprises and agencies.

[1] Likewise, the SEITV is responsible for proposing and carrying out the government policy on housing access, soil and architecture; innovation, quality and sustainability of building and of urban development policies according to the Sustainable Development Goals and the International Urban Agendas.

With this reform, the secretary of state loses the powers on housing that the undersecretary of development assumed.

Due to the economic crisis and the need to cut public spending, in late 2011 a multitude of competencies spread across various bodies were unified in a single one called Secretariat of State for Infrastructure, Transport and Housing, which was developed with a similar structure to that of the secretary of state for infrastructure and transport of 1996.
