A regulated plot (UPI) is the unit in the municipality's detailed development plan, with a Roman numeral and a block number. The first describes what is there, the second what can be built. When the two do not match, either the plan or the cadastral map is amended.<\/p>\n<\/div>\n<h2 id=\"s1\">Land plot (PI)<\/h2>\n<p>A land plot is a piece of the earth's surface with boundaries shown on the cadastral map. Every land plot has an identifier, for example 10135.xxxx.yyy for a plot in Varna. The cadastral map describes the actual situation: boundaries, area, buildings and use. It is maintained by the Geodesy, Cartography and Cadastre Agency.<\/p>\n<h2 id=\"s2\">Regulated plot (UPI)<\/h2>\n<p>A regulated plot is a property whose boundaries, street regulation and building rules have been set by a detailed development plan. It is written with a Roman numeral, the plot number and the block, for example \"UPI III-123, block 45\". The plan is prepared and approved by the municipality.<\/p>\n<h2 id=\"s3\">Why one property has two numbers<\/h2>\n<p>The two systems have different purposes. The cadastre says what exists and who owns it. The regulation says what can be built and how. That is why a notarial deed or sketch often shows both a cadastral identifier and a UPI number.<\/p>\n<h2 id=\"s4\">When they differ<\/h2>\n<ul>\n<li>when the plan is older than the cadastral map and was based on old data;<\/li>\n<li>when the plot has been split or merged but the plan has not been amended;<\/li>\n<li>when the street regulation takes part of the plot;<\/li>\n<li>when there are errors in the cadastral map.<\/li>\n<\/ul>\n<h2 id=\"s5\">What to do<\/h2>\n<p>First, establish which of the two is correct according to the ownership documents. If the error is in the cadastre, it is corrected with a <a href=\"\/en\/uslugi\/kadastr\/\">cadastral map amendment project<\/a>. If the plan does not meet your needs, for example you want to build differently or split the plot, the answer is an <a href=\"\/en\/uslugi\/pup\/\">amendment to the detailed development plan<\/a>. The two procedures often go together.<\/p>\n<h2 id=\"s6\">Frequently asked questions<\/h2>\n<h3>Can I build on a land plot without a UPI?<\/h3>\n<p>In an urban area a detailed development plan that regulates the plot is usually required. On agricultural land, the land use is changed and a plan is prepared before construction.<\/p>\n<h3>Who issues a sketch for a regulated plot?<\/h3>\n<p>The municipality issues a copy of the plan. The sketch of a land plot is issued by the Geodesy, Cartography and Cadastre Office.<\/p>\n<h3>How long does a plan amendment take?<\/h3>\n<p>The procedure has several stages at the municipality and takes longer than a cadastral map amendment. You will receive an indicative timeframe after we have researched the property.<\/p>\n<div class=\"rc-author\"><img decoding=\"async\" src=\"\/wp-content\/uploads\/raychev-design\/raychev-co-logo-96.webp\" width=\"60\" height=\"60\" alt=\"Raychev &amp; Co.\"><\/p>\n<div><b>Eng.
