How to legalize a house on rural land in Peru

A significant part of Peru's housing stock is built on land that never had a title registered with SUNARP: rural possessions, plots informally subdivided around northern Lima, houses built on communal land in the highlands and jungle. When the time comes to sell, mortgage or pass them on, a serious problem appears: without a title, no bank. This article walks through how to legalize a house on rural land in Peru, from possession to SUNARP registration.

Two legalizations, not one

To have a fully salable property, two things must be resolved in parallel:

1. The land, which needs a title of ownership recorded in SUNARP.
2. The building, which must have a fábrica declaration or a regularization procedure (Law 27157 / Law 29090).

Only when both are recorded does the property work as a full financial asset.

If the land comes from informal possession

Most rural cases are resolved with COFOPRI (Informal Property Formalization Body) or, in areas not covered by its campaigns, through notarial or judicial adverse possession.

COFOPRI

COFOPRI runs mass formalization processes on behalf of the State. Its stages:

1. Cadastral diagnosis of the population center or polygon.
2. Possessor census and on-site verification.
3. Qualification: confirms effective, peaceful and public possession.
4. Award resolution or recognition of the right.
5. Registration with SUNARP at a subsidized cost.

The program works mainly in registered shantytowns and rural population centers; for isolated plots the notarial route is preferable.

Notarial adverse possession

Under Law 27333, a possessor can ask a notary public to recognize them as owner if they prove:

• Continuous, peaceful and public possession for 10 years (5 with just title and good faith).
• Documentation: sworn statement, self-appraisal filed with the municipal SAT, utility bills, witness statements.
• Perimeter plan signed by a cadastral verifier.

If no one objects within the publicity periods, the notary issues a public deed and registers it at SUNARP. If there is opposition, it goes to the courts.

If the land is communal

Peasant and native communities have their own legal personality and a special regime. For a community member or a third party to acquire fully:

1. Communal assembly approving the transfer or plot assignment.
2. Recorded agreement in the Minutes Book and at SUNARP (Legal Persons Registry).
3. Independization of the assigned plot in the Property Registry.
4. Physical-legal title clearance and georeferenced plan.

Without a formal assembly and a recorded agreement, any "sale" of communal land is null.

Regularizing the building

With the land registered, you proceed to regularize the building. The standard procedure is Law 29090 and, for old or informal constructions, Law 27157 on building regularization:

1. Architectural survey signed by a registered architect.
2. Descriptive memo and fábrica declaration.
3. If the work was built without a license: Single Building Form (FUE) under regularization, with a fine equivalent to a percentage of the construction cost (between 1 % and 10 % depending on the municipality).
4. Municipal verifier signs the FUE.
5. Payment of the updated self-appraisal to the municipal SAT.
6. Notary issues the public fábrica declaration and submits it to the SUNARP Property Registry for recording.

If the zoning is rural or agricultural

On land classified as rural or agricultural, before regularizing the building you must check the municipal zoning. If the building is the rural owner's dwelling and the municipality considers it compatible, regularization is allowed with limited footprint and height. If the building constitutes a change of use (collective housing, commerce), the following are usually required:

• Zoning change through a provincial ordinance.
• Contributions to public recreation, roads and education.
• Environmental impact study as the case may be.

Without compatible zoning, neither the municipality nor the notary will record the fábrica.

Typical costs in a real case

A family in Cañete inherited a house built on 800 m² of rural land without title. Their journey:

• Georeferenced perimeter plan: S/ 1,800.
• Notarial adverse possession: S/ 4,200.
• SUNARP land registration: S/ 950.
• Architectural survey and fábrica declaration: S/ 3,600.
• FUE under regularization and municipal fine: S/ 2,100.
• Fábrica registration at SUNARP: S/ 750.
• Total: S/ 13,400 and 11 months.

The market value of the property went from S/ 180,000 (sellable only in cash) to S/ 320,000 (eligible for MiVivienda Loan).

When it is worth it and when it is not

Legalizing is worth it when:

• The home is the main residence and you plan to pass it on.
• You intend to sell to a buyer with a mortgage.
• There is a risk of invasion or boundary disputes.

It is less worth it when:

• The land is in a marginal river strip, on an unstable slope or inside an ANP of indirect use.
• Zoning blocks residential construction and changing it is not viable.
• The procedure cost exceeds the expected increase in value.

Final recommendations

1. Gather all the possession documentation (SAT self-appraisal, receipts, contracts, old photos).
2. Hire a registered cadastral verifier.
3. Ask first about COFOPRI: if the sector is in process, avoid paying separately.
4. Work with a single notary that coordinates land and fábrica.
5. Request certificates that you are not on a marginal strip (ANA) and, if applicable, SERNANP opinion.
