The first step required for building a fence in Romania is obtaining a certificate of urbanism from the city hall. Afterwards, the architect will prepare the DTAC - Technical Documentation for obtaining the Building Permit. This documentation will include: a site plan - a topographic base for the execution project of the object to be designed and executed, and a specific technical memorandum with a description of all the components of the fence, including materials used, textures, and execution details.
The validity of the building permit is 12 calendar months and can be extended for no more than 24 months. Depending on the regulations specific to your area, a different set of documentation or procedures might be needed.
