The right of surface (derecho de superficie) in Spain: building on land you do not own under RDL 7/2015 (2026)

The derecho de superficie is a real property right that lets you build on, over, or under land that belongs to someone else, and hold temporary ownership of what you construct for up to 99 years. Articles 53 and 54 of the Real Decreto Legislativo 7/2015, the Texto Refundido de la Ley de Suelo y Rehabilitacion Urbana, regulate it as a registrable, transmissible, and mortgageable right distinct from both a lease and an easement. The mechanism is used by developers building on municipal land, by private parties separating ownership of a building from ownership of the ground beneath it, and by public administrations managing social housing without disposing of their land portfolio.

What is the derecho de superficie under RDL 7/2015?

Article 53.1 of RDL 7/2015 defines the right of surface as a real right (derecho real) that attributes to the superficiario the faculty to realise constructions or edifications on the surface (rasante), in the airspace (vuelo), and in the subsoil of a finca owned by another party, maintaining temporary ownership of the constructions or edifications built. The article adds that the right can also be constituted over existing constructions or edifications, or over dwellings, premises, or privative elements of a construction, granting the superficiario temporary ownership of those elements without prejudice to the separate ownership of the land by its holder.

This is the defining feature that separates the derecho de superficie from every other land-use mechanism. The superficiario does not merely use someone else’s land, as a tenant would. The superficiario owns what they build, separately from who owns the ground, for the duration of the right. That ownership is a real right: it is registrable in the Land Registry, opposable against third parties, transmissible, and mortgageable. When you buy a villa on the Costa del Sol, your title is an absolute real right over both land and building as a single unit. Under a derecho de superficie, the two are split: the landowner keeps the ground, the superficiario keeps what stands on it, and both hold registrable real rights that run in parallel for a fixed term.

The right is supplementary governed by civil legislation in matters not covered by the Ley de Suelo, and by the terms of the constituting title (Article 53.4). This means the Codigo Civil fills gaps, and the parties have broad freedom to set the commercial terms in the deed.

How is a derecho de superficie validly constituted?

Article 53.2 sets two cumulative requirements for valid constitution. First, the right must be formalised in a public deed (escritura publica). Second, that deed must be inscribed in the Property Registry (Registro de la Propiedad). The Land Registry inscription is constitutive, not merely declarative: without it, the derecho de superficie is not validly constituted. This is a harder requirement than applies to most real rights under the Ley Hipotecaria, where inscription is declarative and the right exists between the parties from the moment of the deed. For the derecho de superficie, the legislature made registration a condition of validity itself.

The deed must fix the duration of the right, which cannot exceed 99 years. Only the owner of the land, whether public or private, can constitute the right. A non-owner cannot grant a surface right, and a surface right constituted by someone who is not the landowner is void.

Article 3 of the Ley Hipotecaria (BOE-A-1946-2453) reinforces the deed requirement: titles inscribed in the registry must be consigned in escritura publica, ejecutoria, or an authentic document issued by a judicial authority or the government. The DGRN Resolution of 16 April 2010 (BOE-A-2010-9073) confirmed this point directly, holding that an administrative document is insufficient to inscribe a derecho de superficie and that a public deed is required. The registradora in that case had refused to inscribe a surface right formalised only through an administrative act, and the DGRN upheld the refusal.

Article 2 of the Ley Hipotecaria lists the acts subject to inscription, including in its second paragraph the constitution, recognition, transmission, modification, or extinction of rights of usufructo, uso, habitacion, enfiteusis, hipoteca, censos, servidumbres, and other real rights of any kind. The derecho de superficie falls within that catch-all of otros cualesquiera reales, confirming its registrability.

What did the 2025 DGSJFP resolution clarify about georreferenciacion?

The DGSJFP Resolution of 3 June 2025 (BOE-A-2025-13507), published in the BOE on 2 July 2025, addressed whether a derecho de superficie requires prior georeferenced graphic representation of the affected portion of the finca for registration. The Directorate General held that the constitution of a surface right is not among the cases of obligatory inscription of graphic representation under Article 9 of the Ley Hipotecaria. Prior georeferenciacion is only required when there are reasonable doubts that the delimited portion of the finca over which the right falls is actually located within the registered finca.

In the specific case, the registradora had refused inscription citing identity doubts because the surface right did not extend over the entirety of the finca. The DGSJFP held that the fact the right covers only part of a finca does not, by itself, justify refusing inscription. Where there is no demanial invasion, the coordinates in the plan attached to the title match those in the registered description, and the area covered does not exceed the registered cabida, the registrar should inscribe. However, the resolution did uphold the refusal for one of the two fincas in the case, because its registered description needed rectification and simultaneous inscription of its georeferenced graphic representation through the procedures in Articles 199 and 201 of the Ley Hipotecaria.

This matters for buyers and developers because it clarifies that a partial surface right, one that covers only part of a larger registered finca, can be inscribed without forcing a full georeferencing process, provided the basic identity of the finca is not in doubt.

How does the derecho de superficie differ from a lease and an easement?

Feature	Derecho de superficie	Lease (arrendamiento)	Easement (servidumbre)
Legal nature	Real right (registrable, opposable, transmissible, mortgageable)	Personal right (obligational, not registrable as ownership)	Real right, but passive burden
What the holder gets	Ownership of the construction built on, over, or under the land	Right of use and enjoyment of the property	Right to use or restrict use of the servient land
Can the holder build?	Yes, and owns what is built	Only with landlord consent, no ownership of improvements	No, it is a passive right of use or tolerance
Duration	Up to 99 years (Art 53.2)	Set by LAU or contract terms	Permanent unless extinguished (Art 546 CC, 20 years non-use)
Registration	Constitutive (Art 53.2: deed + inscription required for validity)	Registrable but not constitutive (LH Art 2.5)	Registrable but not constitutive
On expiry	Landowner acquires construction without indemnification (Art 54.5)	Tenant returns property, no automatic transfer of improvements	Burden extinguishes, no transfer of anything

The distinction from a lease is the most practically important. A lease gives you the right to use and enjoy a property for a time, but you never own it, and anything you build typically belongs to the landlord unless the contract says otherwise. The derecho de superficie splits ownership: the land is one thing, the construction is another, and the superficiario holds the second as a real right. That is why it can be mortgaged, sold, and inherited as property in its own right, which a leasehold cannot.

The distinction from an easement (servidumbre) is structural. An easement is a passive burden: the servient land must tolerate a use or abstain from a use, but the easement holder does not build, does not own anything, and does not gain an active faculty of construction. The derecho de superficie is an active right to build and to own the result. If you need a right of way across a neighbour’s land, that is a servidumbre de paso. If you need to build a commercial structure on municipal land and own the building for 75 years, that is a derecho de superficie.

What are the public and private variants?

The derecho de superficie has two main forms. The public variant involves a public landowner, typically a municipality or a regional housing agency, granting a surface right to a private developer or operator. The private variant involves two private parties, where a landowner grants a surface right to a developer or investor without selling the land.

The public variant is the more visible in practice. The Junta de Andalucia, through its housing agency AVRA (Agencia de Vivienda y Rehabilitacion de Andalucia), has used surface rights to build social housing on public land without disposing of the land itself. In April 2023, the BOJA published a tender for the award of a 75-year surface right on a 4,217 square metre parcel in Algarrobo, Malaga, for the construction and management of up to 48 protected rental units. The project, part of the Ecovivienda programme, had a global budget of EUR 7.8 million, of which EUR 2.1 million came from Next Generation EU funds. The surface right lets the private operator build and manage the housing for 75 years, after which the land and everything on it returns to the public owner.

The private variant is used for commercial development on land the owner does not want to sell, for vertical separation of ownership (where one party owns the land and another owns the building above), and for structures built over public infrastructure such as transport corridors. The 99-year ceiling under Article 53.2 is long enough to amortise a commercial building and return the land to the owner at expiry.

How is the derecho de superficie transmitted and encumbered?

Article 54.1 provides that the surface right is susceptible to transmission and encumbrance, subject to the limitations fixed in the constituting deed. The superficiario can sell the right, mortgage it, or pass it to heirs, and the landowner cannot block these acts unless the constituting deed explicitly restricts them.

Article 54.2 adds a powerful faculty. When the characteristics of the construction permit, the superficiario can constitute the superficiarian property in a horizontal property regime (regimen de propiedad horizontal), separating the terrain belonging to the landowner, and can transmit and encumber the dwellings, premises, and privative elements of the horizontal property as independent fincas during the term of the surface right, without needing the landowner’s consent. This means a developer holding a surface right on municipal land can build a block of apartments, split them into horizontal property units, and sell each unit individually, all while the municipality retains ownership of the ground beneath.

Article 54.3 allows the constituting deed to include rights of first refusal (tanteo), retraction (retracto), and repurchase (retroventa) in favour of the landowner, for cases where the superficiario transmits the right or its elements. This gives the landowner a mechanism to recover the right or the built units before the term expires, if the commercial agreement so provides.

Article 54.4 grants the landowner a parallel right to transmit and encumber their land separately from the superficiario’s right, without needing the superficiario’s consent. The subsoil belongs to the landowner and is transmitted and encumbered together with the land, unless it has been included in the surface right grant. This means the landowner can sell the land to a third party while the surface right runs, and the buyer takes subject to the registered surface right.

How and when does the derecho de superficie extinguish?

Article 54.5 sets two routes to extinction. First, the right extinguishes if the superficiario fails to build in accordance with the territorial and urban plan within the period set in the constituting title. This is an early termination for non-performance, and it protects the landowner against a superficiario who holds the right idle. Second, the right extinguishes by the passage of the agreed duration term.

On extinction by term expiry, the landowner acquires ownership of everything built, without paying any indemnification, regardless of how the right was constituted (Article 54.5). The parties may, however, agree liquidation rules for the surface right regime in the constituting deed, which is the only way to soften the no-indemnification default.

Extinction by term expiry also determines the extinction of every real or personal right the superficiario imposed on the construction (Article 54.5). Mortgages on the building, leases of the units, and other charges all dissolve when the surface right ends and the landowner reacquires the construction. This is why lenders financing a superficiario’s construction typically align their mortgage term with the surface right term.

If ownership of the land and the surface right reunite in one person for a reason other than term expiry, the charges on each right continue to burden them separately until the surface right’s term runs out (Article 54.5). This prevents a merger from accidentally extinguishing charges that should survive the consolidation.

What tax treatment applies to the derecho de superficie?

The tax treatment follows the three-stage pattern that applies to transaction structures involving an initial act, a potential exercise, and a potential expiry. At constitution, the grant of the surface right is treated as a transmission of the right, subject to transfer tax (ITP) on the value of the right granted, or VAT (IVA) if the grantor is a business. At transmission of the surface right or its horizontal property units, the same rules apply as to any property transfer: ITP on resale, IVA plus AJD on new build. At extinction by term expiry, the reversion of the construction to the landowner is not a taxable transfer, because it occurs by operation of law under Article 54.5, though the specific treatment depends on how the parties structured the liquidation clause and whether the construction had been split into horizontal property units.

Anyone considering a derecho de superficie should verify the exact tax position with a Spanish tax advisor (asesor fiscal), because the treatment varies by whether the grantor is public or private, whether the right is onerous or gratuitous, and whether the construction is sold as horizontal property units during the term.

What should a buyer or developer check before entering a surface right?

Four points matter before signing a surface right deed. First, confirm the grantor is the registered owner of the land and that the land is free of charges that would block the inscription, because Article 53.2 requires both a public deed and registry inscription for validity. Second, fix the duration in the deed, knowing the 99-year ceiling is a hard cap. Third, negotiate the liquidation clause if you want anything other than the default no-indemnification reversion at expiry, because without a clause the landowner takes everything built for free. Fourth, check the urban plan to ensure the construction you intend is permitted, because failure to build according to the plan within the set period triggers early extinction under Article 54.5.

The property registration process is the foundation of the surface right’s validity, so the nota simple should be the first document your lawyer pulls. The coastal law guide is essential reading if the land is anywhere near the shoreline, because coastal land carries public-domain restrictions that interact with surface rights in ways the Ley de Costas governs. The property valuation guide matters because the value of a surface right is not the value of the land, it is the value of the right to use it for a fixed term, which is a different appraisal question.
