Lottizzazione

Lottizzazione is a term used in urban planning to describe the subdivision of a larger real estate area into smaller plots, or lotti, intended for construction and development. It is a mechanism that translates planning policies into physical parcels ready for building, often allowing residential, commercial, or mixed-use projects.

In practice, the lottizzazione process involves the preparation of a piano di lottizzazione (subdivision plan) by the landowner or developer, detailing the division of the land into plots, the layout of internal roads, utilities, and any public spaces or green areas. The plan also specifies the works of urbanization required to make the area usable, such as road networks, drainage, water and sewer systems, and street lighting. The proposal is submitted to the municipal authorities, which review it in light of the local zoning plan and urban regulations. If approved, the plan becomes binding through urbanistic agreements or conventions (convenzioni urbanistiche) that assign duties and costs to the developer.

After approval, plots are transferred or sold to builders who obtain the necessary building permits and carry out the construction in compliance with the approved plan and zoning rules. The process aims to ensure that new development is accompanied by essential infrastructure and public services and that it respects environmental and urban integration requirements.

Lottizzazione can be a subject of debate, particularly concerning urban sprawl or speculative development, and is regulated to balance private interests with public value.
