Protection zones and setbacks — Italy
Choose a zone and check the planning passport: how many metres, what is forbidden inside, a by-country table and source links.

Electricity
Power line protection zone
The protection zone of an overhead power line is measured from the outer conductors on each side and grows with voltage. Inside it, building and many works need the grid operator’s consent.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Electricity
Underground cable protection zone
A buried power cable has a narrow protection strip on each side. Over it, building and earthworks are restricted to keep the cable accessible and undamaged.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Water source
Well / borehole sanitary zone
Around a drinking-water source you may not place contamination sources. The zone protects the water from septic systems, toilets, compost and chemical stores.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Sanitation
Septic tank distances
A septic tank is placed at a distance from the house — so it does not undermine the foundation and odour does not reach the windows — and well away from any drinking-water source, since leaks can contaminate a well or borehole. A setback from the boundary is also kept so the tank stays accessible for servicing and pumping.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Sanitation
Outdoor toilet / cesspit distances
An outdoor toilet or cesspit is placed well away from any drinking-water source so that seepage cannot reach a well or borehole, and at a distance from dwellings — your own and the neighbour’s — for sanitary reasons and to keep odour away.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Sanitation
Bathhouse / shower distance
A bathhouse, sauna or outdoor shower is set back from a dwelling — because of water runoff, humidity and the fact that a stove is a fire source — and a setback from the plot boundary is kept as well. The exact distances depend on the country and the building materials.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Sanitation
Compost distance
A compost heap or manure pile is placed away from any drinking-water source so that organics and seepage do not reach a well or borehole, and with a setback from the boundary so odour and moisture do not disturb the neighbour.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Setbacks
House setback from the boundary
A dwelling must stand at least the setback distance from the neighbouring boundary; you may not build the house in the strip between that line and the boundary.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Setbacks
Outbuilding setback
Outbuildings — a shed, garage, bathhouse or greenhouse — are set back from the neighbouring boundary: you may not build in the strip right next to it. The roof slope and drainage must also stay within your own plot and not shed water or snow onto the neighbour. The exact distance depends on the country and local development rules.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Fire safety
Fire gap between houses
The fire gap between dwellings depends on wall and roof materials. No structures or flammable storage are allowed within the gap.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Planting
Tree and shrub planting distance
Tall trees are planted farthest from the boundary, shrubs closest, so crown and roots do not shade or damage the neighbour’s plot or utilities.
Unless local regulations or established local customs provide otherwise, Article 892 requires 3 m for tall trees, 1.5 m for non-tall trees and 0.5 m for vines, shrubs, live hedges and fruit trees no taller than 2.5 m. A dividing wall without openings can trigger the statutory exception.
Setbacks
Setback from a public road
A public road has red lines and a building setback. Near a street the building is set back from the red line; along regional or federal roads a wider roadside strip restricts construction. A public road is part of the urban-development plan — unlike a garden path.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Water bodies
Pond distance from the boundary
An ornamental pond is set back from the plot boundary so it stays accessible and water does not seep to the neighbour, and kept away from a drinking-water source so it cannot contaminate a well or borehole.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Water bodies
Pool distance from the boundary
A swimming pool is treated as an "other structure": it is set back from the plot boundary so it stays accessible for servicing and drainage. Clean pool water is not a contamination source, so there is no sanitary distance to a well.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Fire safety
Fire pit / BBQ clearance
Open fire — a fire pit or BBQ — is kept clear of buildings, fences and anything flammable, so sparks and heat cannot start a fire. The exact clearance depends on the country and local fire rules.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
Sanitation
Animal / poultry house setback
A building for poultry or small animals is kept further from the boundary than an ordinary shed, for sanitary reasons — odour, runoff and noise should not disturb the neighbour. The exact setback depends on the country.
National civil-law rules are only a baseline. Check the regional rules and the current municipal planning instrument before fixing the zone.
