According to a tweet by Barcelona's deputy mayor Janet Sanz, the permit comes after "130 (years) of unlicensed work."
The basilica's construction committee will pay the city of Barcelona 4.6 million euros (about $5.2 million) for the license. La Sagrada Familia receives around 4.5 million visitors a year, so the money will help cover the basilica's preservation as well as a new metro stop to take visitors directly to the site.
The permit allows a maximum height of 172 meters (564 feet), which would make it the tallest building in Barcelona, and a budget of 374 million euros, according to Agence France-Presse.
Catalan architect Antoni Gaudí is also known for creating Casa Milá, Park Güell, Casa Batlló and Church of Colonia Güell among others. Gaudí dedicated himself to working solely on the basilica in 1914 until his death in 1926. The Sagrada Familia was declared a UNESCO World Heritage Site in 2005.
