Illegal Construction Defense Lawyers (Art. 319 CP)

Specialized criminal defense against unauthorized construction on protected land

Illegal construction or building (Art. 319 of the Spanish Criminal Code (CP)) punishes works that cannot be authorised — and therefore cannot be legalised — on specially protected land or public land, with imprisonment of 1 year and 6 months to 4 years, a fine of 12 to 24 months, and special disqualification of 1 to 4 years (Art. 319.1 CP); on ordinary non-developable land, the penalty drops to imprisonment of 1 to 3 years (Art. 319.2 CP). The judge may also order demolition of the works at the offender's expense. Our defence proves that the works could potentially be legalised, disputes the true classification of the land, and assesses the limitation period for the offence, which is distinct from that of the administrative planning infringement.

Building on non-developable or protected land is not just an administrative infraction, but a crime (Art. 319 CP) that can lead to prison sentences and, most seriously, the demolition of the construction. Our defense focuses on demonstrating possible legalization or the statute of limitations to save your property.

Concept (Art. 319 CP)

The offence of illegal construction or building under Art. 319 CP protects land-use planning and, mediately, the environment and rational use of land. It sanctions urbanisation, construction or building works that are non-authorisable on certain classes of land. The mere lack of a licence does not suffice: the essential element is that the works are non-legalisable for frontally contravening planning regulations. Unlike the administrative infringement, the offence requires this impossibility of legalisation and the involvement of specially protected or non-developable land.

Forms (Art. 319.1 and 2 CP)

The offence distinguishes two levels according to the class of land. Art. 319.1 CP punishes non-authorisable works on land allocated to roads, green areas, public-domain assets or places of recognised scenic, ecological, artistic, historical or cultural value or specially protected. Art. 319.2 CP sanctions non-authorisable building on ordinary non-developable land. The seriousness and penalty are graduated according to the protection level of the affected land, that of Art. 319.1 being more severe.

Penalties and Forfeiture (Art. 319 CP)

The penalties are tiered. Art. 319.1 CP carries 1 year and 6 months to 4 years' prison, a fine of 12 to 24 months (unless the profit obtained is higher, in which case it is calculated on it) and special disqualification from profession or trade for 1 to 4 years. Art. 319.2 CP provides 1 to 3 years' prison together with the fine and disqualification. The forfeiture of the profits obtained from the unlawful activity also proceeds, regardless of any transformations they may have undergone.

Demolition (Art. 319.3 CP)

The most feared consequence is demolition. Art. 319.3 CP empowers courts to order, with reasons and at the author's expense, the demolition of the work and the restoration of the altered physical reality to its original state, without prejudice to compensation owed to good-faith third parties. Case-law has consolidated that demolition is not automatic but requires a proportionality assessment. The defence aimed at avoiding it works on possible subsequent legalisation, the proportionality of the measure and the situation of third-party purchasers.

Defence and Limitation

The defence articulates several axes. First, the legalisability of the works: if they can be adapted to the regulations or there is subsequent planning cover, typicity fails. Second, the class of land: proving it was neither specially protected nor non-developable redirects the facts to the administrative route. Third, limitation: the prescription of the offence (according to its penalty) must be distinguished from that of the urban infringement and the restoration action, which follow their own periods; in old constructions, the prescription of the offence may exclude conviction even though the administrative infringement subsists. Fourth, the absence of intent or error about the land classification.

Environmental and Urban Planning Crimes in Spain: Defence Guide

Environmental crimes (Arts. 325-340 CP) and urban planning crimes (Arts. 319-320 CP) are increasingly prosecuted in Spain, especially following EU environmental directives. Directors of companies, urban planners, and public officials can be held personally liable for environmental harm caused by their organisations.

Key Defence Strategies

Challenging the 'Serious Risk' Threshold

Art. 325 requires a serious risk to natural equilibrium or human health. If the environmental impact was minor, temporary or fully remediated, the prosecution must prove the risk threshold was met. Independent expert reports are decisive.

Regulatory Compliance Defence

Environmental crimes require acting contrary to administrative regulations. Demonstrating that the activity was authorised, had all required permits, and complied with applicable administrative restrictions is a complete defence.

Urban Planning: Land Classification Challenge

For Art. 319, whether the land is 'non-buildable' or 'specially protected' is often disputed. Urban planning law is complex and classifications change. Challenge the applicable land classification at the time of construction.

Individual Liability of Corporate Managers

Directors can be prosecuted for acts of the company if they knew about and failed to prevent the environmental harm. The defence challenges: (1) their actual knowledge, (2) their factual ability to prevent it, and (3) whether they relied on specialist authorisations.

FAQ: Illegal Construction & Urban Planning

Are works without a licence a crime?
Not always. They are only a criminal offence under Art. 319 CP where building takes place on specially protected non-developable land or in public-domain areas without authorisation. Minor works without a licence are an administrative infringement.
What penalty do illegal works carry?
One to 3 years of imprisonment, a fine of 12 to 24 months and special disqualification from the profession or trade for 1 to 4 years. Demolition of what was built may also be ordered.
What is specially protected non-developable land?
Land given special protection for its environmental, landscape, historical or strategic value: protected natural areas, the coastline, river beds, areas of special ecological interest.
Is building on the coast a crime?
Yes, where building takes place on the maritime-terrestrial public domain or within the protection easement zone without authorisation. The Coastal Act imposes very strict restrictions.
Who can be liable for this offence?
The developer and the builder are principal offenders. Site managers, architects and technical officers who take an active part may be necessary cooperators or instigators.
Can the architect be convicted?
Yes. An architect who designs and directs works they know to be illegal may be liable as a necessary cooperator in the planning offence. Their professional-conduct liability is also very serious.
Is it a crime to extend a house on rural land?
If the extension is built on specially protected non-developable land without a licence, yes. On generic rural land it may be a crime or an administrative infringement, depending on the autonomous community.
Is demolition mandatory?
The judge may order the demolition of the illegal works, and frequently does. Demolition is carried out at the convicted person's expense. It is independent of the criminal penalty.
Can the buyer of an illegal house be convicted?
The buyer is not usually liable for the offence of illegal construction (committed by the builder). But buying a home knowing it is illegal can give rise to civil liability.
Can illegal works be legalised?
It depends on municipal and regional planning rules. Some laws allow works to be regularised if a licence is obtained afterwards. But works on protected land are generally not capable of being legalised.
What is planning limitation (prescripcion urbanistica)?
After a set period (4-8 years depending on the autonomous community) without sanctioning proceedings, the administrative infringement lapses. But criminal offences do not lapse merely through the passage of time without administrative action.
Can the town council report illegal works?
Yes. The town council has a duty to monitor compliance with planning law and to report possible criminal offences to the prosecution service.
Does a mayor who fails to act against illegal works commit a crime?
They may commit planning misconduct in office (Art. 320 CP) if, knowing of the illegality, they grant a licence or deliberately fail to exercise their inspection duties.
What is planning misconduct in office?
An official who issues a favourable report on, or grants a licence for, manifestly illegal works commits the offence under Art. 320 CP, punishable with 6 months to 2 years of imprisonment plus disqualification.
Do greenhouses and agricultural installations need a licence?
It depends on regional legislation. In many autonomous communities, greenhouses and agricultural structures on rural land have a special regime that may not require a building licence as such.
Is building a swimming pool without a licence a crime?
On urban land it is generally an administrative infringement. On specially protected non-developable land it may constitute an offence under Art. 319 CP if it significantly alters the land.
Do illegal works become time-barred under criminal law?
The offence under Art. 319 CP becomes time-barred after 5 years. However, where the illegal works remain in place, some courts treat it as a continuing offence that does not become time-barred while it subsists.
Can I report my neighbour's illegal works?
Yes. Anyone may report illegal works to the town council, the planning prosecutor's office or the police. You do not need to be directly affected.
Do prefabricated houses need a licence?
Yes. Prefabricated or modular homes on a concrete slab are buildings for planning purposes and require the same licences as conventional works.
What about illegal works on inherited land?
An heir who knowingly keeps illegal works in place may face administrative planning liability. The original builder's criminal liability is not passed on.
Is there a specialised planning prosecutor's office?
Yes. The specialist Environment and Planning unit of the prosecution service coordinates the prosecution of planning offences nationwide. Each province has a delegated prosecutor.
Do I need a lawyer specialising in planning offences?
Yes. Defence in planning offences requires knowledge of regional planning law, municipal planning instruments and the complex interplay between administrative and criminal proceedings.
