Etna Park Restrictions: What You Can and Cannot Build in Zone A, B and C

By Arch. Fabio Costanzo, Studio 4e · Updated: March 2026

The Parco Regionale dell'Etna covers 58,000 hectares across four provinces and 20 comuni on the volcano's slopes. It is divided into three zones that determine what can be built, restored or demolished. Zone A is practically unbuildable. Zone B allows conservative restoration only. Zone C permits limited new construction under specific conditions. Getting this wrong before signing a purchase contract is expensive.

How the Etna park zoning works and where to find your property's zone

The Parco Regionale dell'Etna was established by Legge Regionale Siciliana n.98 of 1981 and is managed by the Ente Parco dell'Etna (headquarters in Nicolosi). The park's Piano Territoriale has three protection zones:

• Zone A (Riserva Integrale): the highest protection level. Covers the summit area, active lava fields, primary forest areas, and the most ecologically sensitive habitats. Human settlement is minimal or absent. Construction of any kind is prohibited, including restoration of existing structures. Agricultural use is severely restricted.
• Zone B (Riserva Generale): covers the main belt of established forest, historic rural settlements, and areas of significant natural landscape. Conservative restoration of existing legally-built structures is permitted. New construction is prohibited except for infrastructure maintenance. Agricultural activity (vineyards, orchards) continues under park management guidelines.
• Zone C (Area di Protezione): the outermost ring, covering the established agricultural and residential areas on the park's periphery. Limited new construction is possible within the limits of the Piano Territoriale and the municipal PRG. Renovation and expansion of existing buildings is permitted subject to park authority parere (non-binding opinion in most cases).

Verify your property's zone: the Ente Parco dell'Etna website provides a GIS viewer, or request a certificato di destinazione d'uso from the park authority. The certificato takes 10–20 working days and costs €100–200. Do not proceed with any purchase without this verification.

Zone A: why it is effectively unbuildable and what buyers find there

Properties marketed as being "within the Etna park" sometimes include Zone A parcels that technically cannot be developed at all. Common scenarios:

• Agricultural land (mostly lava rock, low productive value) with old stone walls or rudimentary structures predating the park's establishment. The structures may technically exist in the cadastre, but Zone A prohibits any construction work on them — not even weatherproofing a roof to prevent further deterioration.
• Parcels purchased by buyers who believed the park zone was Zone C but found after purchase that the zone boundary bisects the property, placing the buildable part in Zone B and the non-buildable part in Zone A.
• Former agricultural terraces (terrazzamenti) with no existing structures, marketed as "building plots" on the basis of historic cadastral entries that predate the park establishment.

Zone A land has value only for agriculture (if viable) and as natural landscape. It should be priced accordingly — not as a construction opportunity. If an agent is presenting a Zone A parcel with a structure at a price implying renovation potential, get the zone certificate before committing.

Zone B: conservative restoration — what is and is not allowed

In Zone B, the Parco dell'Etna applies specific building rules through its Piano Territoriale and Norme di Attuazione:

Permitted works in Zone B:

• Restoration and conservation of existing legally-built structures, maintaining the original volume and footprint
• Ordinary maintenance (manutenzione ordinaria): replacing broken roof tiles, repointing external walls, repainting with approved colour palette
• Extraordinary maintenance (manutenzione straordinaria): replacing internal fixtures, updating impianti (electrical, plumbing) without structural modification
• Agricultural infrastructure maintenance: dry-stone wall (muri a secco) repair, access track surfacing with permeable materials

Prohibited in Zone B:

• Volume increases: no additions to existing structures, even small porticoes or wood sheds
• Demolition and reconstruction: even at the same volume, because the park requires preservation of existing fabric
• New structures of any kind: garden walls over 60 cm, outbuildings, pool houses, satellite dishes above a certain size
• Removal of existing vegetation: protected Etna species (ginestra dell'Etna, betula dell'Etna) cannot be removed without specific park authorisation

The practical consequence: a Zone B farmhouse can be made habitable and comfortable but it cannot be expanded. If you need more space than the existing structure provides, Zone B is the wrong purchase. An existing 80 sqm farmhouse in Zone B remains 80 sqm unless the park authority grants an exceptional derogation — which is rare and requires a specific justification in the public interest.

Zone C: where limited new construction is possible

Zone C in the Etna park is more permissive but not the same as standard Italian building rules. The additional layer is a required parere dell'Ente Parco for projects that affect the park's visual and environmental character. In Zone C:

• New construction up to the limits of the municipal PRG is generally possible, but requires the park's parere in addition to the standard municipal permit
• The parere is non-binding in most cases (the municipality is not legally obliged to follow it), but rejection of the parere creates a political obstacle that experienced architects navigate carefully
• External materials must respect the park's visual guidelines: use of natural volcanic stone, terracotta tile, and lime render is encouraged; reflective materials, vivid colours, and large glazed surfaces facing the summit are discouraged
• Swimming pools in Zone C are permitted by the park but are subject to the same conditions as elsewhere: structural engineering, permit process, and compliance with the park's guidelines on water features in the volcanic landscape

The Zone C comuni include most of the inhabited Etna wine belt towns — Zafferana Etnea, Milo, Castiglione di Sicilia, Passopisciaro, Solicchiata — where the high-end volcanic wine production (nerello mascalese, etna DOC) has created a significant market for wine estate properties. Most of the luxury masseria and wine property conversions that attract international buyers on the Etna slopes are in Zone C.

The Etna-specific materials requirement and what it means in practice

The Ente Parco requires that restoration and new construction within the park use materials consistent with Etna's vernacular architectural tradition. In practice:

• External walls: lava stone cladding or lime render in earth tones (grey, ochre, terracotta). Smooth white render — standard in coastal Sicilian architecture — is not accepted within the park. Modern render systems (silicone, acrylic) are accepted only if the colour complies with the park palette.
• Roof covering: traditional Sicilian terracotta curved tiles (coppi siciliani). Modern concrete tiles are not accepted. Photovoltaic panels on roofs are permitted with specific placement conditions (not visible from key park viewpoints).
• Joinery: wooden window frames preferred; powder-coated aluminium accepted in dark colours (anthracite, dark brown). Bright white aluminium frames are discouraged.
• Boundary walls: dry-stone lava rock walls are the accepted vernacular. Concrete block walls must be faced with lava stone. Open metal fencing is preferred to solid masonry walls in landscape-sensitive locations.

These material constraints add cost — lava stone cladding costs €80–130/sqm vs cement render at €25–45/sqm — but they also ensure that renovated properties retain the visual character that drives property values in the Etna wine belt. The constraint is simultaneously a quality control mechanism.

The Etna eruption risk and its interaction with planning

Etna erupts regularly — major lava flows in 2001, 2002–03, 2019, and 2022 affected inhabited areas on the northern and southern slopes. The Piano Regolatore Generale of the affected comuni includes lava risk zones (zone a rischio lavico) that restrict new construction in historically threatened corridors. The 2002 eruption caused property losses in Linguaglossa commune.

Check the lava risk classification for any property on the Etna slopes, particularly on the northern flank (Nicolosi–Rifugio Sapienza corridor) and the north-eastern flank (Piano Provenzana area). Properties in high lava risk zones are effectively uninsurable for lava flow damage — Italian insurers uniformly exclude this peril. The risk is location-specific: properties more than 300–500 metres from established lava corridors are at low risk in statistical terms, but any buyer should understand the history of flows in the specific area.
