A buyer is about to sign a contract for an apartment with a private garden listed as 150 m\u00b2 in the ad. Upon checking the cadastral map, it turned out that the lot did indeed measure 150 m\u00b2\u2026 but that figure included the building\u2019s footprint and the common areas. The actual garden? Barely 40 m\u00b2. This example is obviously fictional, but it\u2019s not so far removed from the mishaps people have experienced with the cadastral registry\u2014an administrative tool that everyone consults but few truly understand.<\/span><\/p>\n Our years of expertise in the 16th arrondissement have taught us to interpret these documents in a rigorous and pragmatic manner. Between the easements inherited from Baron Haussmann and the successive subdivisions of land parcels, reading the cadastral records in our neighborhoods requires a trained eye and a solid knowledge of the area.<\/span><\/p>\n As you are no doubt aware, the cadastral registry maintains a comprehensive inventory of all real estate properties in the territory. Each parcel is listed, numbered, and demarcated. However, contrary to a common misconception, the cadastral registry does not establish ownership.<\/span><\/p>\n Only the <\/span>title deed<\/span><\/a> The notarized document is authoritative in this matter. The land registry actually serves a tax-related purpose. In short, the land registry is primarily used to assess property taxes.<\/span><\/p>\n In our district, history makes it somewhat difficult to understand the area, and there are several reasons for this. The large 19th-century estates were broken up, creating layouts that are, to say the least, unusual.<\/span><\/p>\n On Rue de la Faisanderie, for example, some parcels run through buildings, remnants of former private passageways. At Place du Trocad\u00e9ro as well, the cadastral boundaries still follow the layout of the former palace, even though it was demolished in 1937. There are many peculiarities like these.<\/span><\/p>\n The cadastral map consists of two distinct components:<\/span><\/p>\n This distinction is important because many of our clients confuse cadastral area with <\/span>living space<\/span><\/a> actual.<\/span><\/p>\n The land registry can now be accessed online via the portal <\/span>cadastre.gouv.fr<\/span><\/a>. The codes used take some getting used to: \u201cS\u201d for ground, \u201cT\u201d for land, and hatching for buildings.<\/span><\/p>\n In the 16th arrondissement, we frequently come across \u201cflag-shaped\u201d lots. That is, a narrow strip facing the street that widens toward the back. This layout is a remnant of the old stables, which were accessed via passageways.<\/span><\/p>\n Property boundaries are a recurring problem. The cadastral records sometimes date back to 1810, with only sporadic updates. Typically, in a case on Mozart Avenue, the official boundary might literally run through a veranda built in the 1960s. And a boundary survey (conducted by a licensed surveyor) could reveal a 3-meter discrepancy with the cadastral map!<\/span><\/p>\n What you need to understand is that the cadastral record is based on a \u201cpresumption of accuracy,\u201d not absolute truth. In the event of a dispute between neighbors, only the boundary markers are considered authoritative. For a <\/span>real estate appraisal<\/span><\/a> To ensure accuracy, we systematically cross-check the land registry, the title deed, and our on-site inspection.<\/span><\/p>\n L\u2019<\/span>real estate investment<\/span><\/a> often begins with a review of the cadastral records. Identifying large parcels that could be subdivided, locating vacant lots suitable for development, understanding existing easements, and so on. This information serves as a starting point for the savvy investor.<\/span><\/p>\n In our neighborhoods, it\u2019s not uncommon for certain cadastral anomalies to create opportunities. In Villa Montmorency, for example, several properties have forgotten, undeveloped lots that are taxed as gardens\u2014even though they\u2019re zoned for construction. On Avenue de Versailles, poorly defined shared courtyards sometimes allow for extensions after approval by the co-owners.<\/span><\/p>\n Consulting the land registry also reveals easements\u2014rights that encumber your property for the benefit of others. These include rights of way to access landlocked parcels, view rights that prohibit certain openings, and rights for stormwater drainage. In the dense urban fabric of the 16th arrondissement, these restrictions directly impact the value and use of properties.<\/span><\/p>\n The digitization of the land registry has certainly made it more accessible, but it has also brought its own set of complexities. Updates are coming more frequently: parcel divisions, lot consolidations, and boundary changes are appearing more quickly. But digitization has also locked in certain historical errors, which are now more difficult to correct.<\/span><\/p>\n The 3D cadastre project, currently being piloted in certain districts, promises an interesting approach. No more approximations for volumes, heights, and overhangs. For our Haussmann-style buildings with complex layouts (souplexes, duplexes, converted attics), this development will bring much-needed clarity.<\/span><\/p>\n The integration with the PLU (Local Urban Planning Plan) is also becoming more refined. Cadastral data is fed directly into urban planning documents, influencing the possibilities for construction or expansion. The <\/span>role of a real estate agency<\/span><\/a> Modern practices now include this cross-referencing of land registry and urban planning data.<\/span><\/p>\n When signing a <\/span>promise or agreement to sell<\/span><\/a>, as you are no doubt aware, the precise cadastral designation of the property is now required.<\/span><\/p>\nThe Cadastral Registry and Its Purpose<\/h2>\n
