The Coastal Law framework

The Coastal Law (Ley 22/1988 reformed by Law 2/2013) establishes the public domain of the coastal zone (Dominio Público Marítimo Terrestre, DPMT) and zones of influence with restricted use. The framework protects the coast and limits private property rights in defined areas.

The DPMT includes: beaches, dunes, intertidal zones, public marine waters, certain ports. Properties within DPMT are not in private ownership; existing structures may have concessions but the underlying land is public.

Zones of protection

Beyond the DPMT itself, the Coastal Law defines zones of influence with restricted use: zone of protection (typically 100m from the inner DPMT boundary, with severe restrictions on construction); zone of influence (typically 500m, with more limited restrictions). Specific provisions vary by zone.

For property in these zones, construction is restricted (new buildings often prohibited; reform of existing buildings limited). Existing properties grandfathered but with constraints. Property values reflect the restrictions.

Property due diligence in coastal areas

For property purchase near the coast, due diligence must verify: location relative to DPMT and zones (the Cadastre and coastal authority maps); status under Coastal Law (whether grandfathered, with concession, etc.); restrictions on future modifications; any active enforcement actions.

Some coastal properties have complex status under Coastal Law (some are partially DPMT with concessions; some have demolition orders due to violations). Due diligence is critical and specialized.

Concessions for grandfathered properties

For properties built before the Coastal Law (1988), with land later included in DPMT, the owner may have a concession (concesión administrativa) allowing continued use for defined period (typically 30 years with possible extensions). After the concession expires, the property reverts to public domain.

For concession properties, the owner does not have full property rights — only the concession rights. Value reflects the remaining concession period. Sale requires transfer of the concession (with administrative approval). The legal regime is specific and requires professional analysis.

Implications for international buyers

Coastal property is often very attractive (beach proximity, views) but the Coastal Law adds complexity. International buyers should: only proceed with thorough due diligence by lawyer specialized in coastal matters; verify legal status carefully; consider the implications of any restrictions on future use and value.

For some coastal properties, the Coastal Law issues may make the property unsuitable for the buyer's intent. For others, the restrictions are manageable but reduce flexibility. The professional advice is essential.

Action steps

First: identify if the property is in DPMT, zone of protection, or zone of influence. Second: review specific status (full ownership, concession, etc.). Third: assess restrictions and their effect on intended use and value. Fourth: factor restrictions into purchase decision. For consultation, contact our team.
