The 'Declaratoria de Fábrica': Why This Document is Essential When Buying a Newly Built or Renovated Home in Arequipa

As a licensed Peruvian real estate broker specializing in Arequipa, I cannot stress enough the critical importance of robust due diligence, especially when considering a newly built or recently renovated property. Among the myriad documents you must meticulously review, the Declaratoria de Fábrica stands out as a foundational pillar of legal certainty for any real estate transaction involving new construction or significant modifications. For expats and foreign investors in Arequipa, understanding this document is not merely good practice – it's an absolute necessity to safeguard your investment.

What is a 'Declaratoria de Fábrica'?

In Peruvian law, the Declaratoria de Fábrica, often translated as "Declaration of Construction" or "Building Declaration," is the formal legal recognition and registration of a building's physical existence and its specific characteristics within the Public Registries (S.U.N.A.R.P. - Superintendencia Nacional de los Registros Públicos).

Simply put, it's the official declaration that a new building or a significant renovation/expansion of an existing structure has been completed according to its municipal building permits and technical plans, and that it now legally exists as described. This declaration is typically prepared by a qualified architect or civil engineer, formalized before a notary public through a public deed, and then inscribed in the property's Partida Registral (Title Record) at S.U.N.A.R.P.

Think of it this way: While a municipal building permit allows you to build, the Declaratoria de Fábrica confirms that you have built according to the permit, and officially updates the legal description of the land to include the structure standing upon it. Without it, your physical property and its legal status are fundamentally mismatched, creating significant liabilities.

Why the 'Declaratoria de Fábrica' is Non-Negotiable for Buyers

For a foreign investor looking to acquire property in Arequipa, bypassing the verification of a proper Declaratoria de Fábrica is akin to buying a car without a title – you might possess it physically, but your legal ownership and future ability to transact with it are severely compromised. Here’s why it is absolutely essential:

Legalizing the Physical Reality: The most fundamental reason. Your property's legal description in S.U.N.A.R.P. must accurately reflect the structure you are buying. If a property is described as a vacant lot or a small one-story home, but physically stands as a three-story residence, there's a significant legal discrepancy. The Declaratoria de Fábrica bridges this gap, ensuring legal and physical realities align.
Facilitating Future Transactions (Sales, Mortgages, Loans):
- Selling: Without a registered Declaratoria de Fábrica for new construction or major renovations, you will face immense difficulty selling the property in the future. No informed buyer, particularly one seeking bank financing, will proceed with a purchase.
- Mortgages/Loans: Peruvian banks will unequivocally refuse to provide a mortgage or accept the property as collateral if the improvements are not legally declared and registered. They require the property's legal status to be fully in order and match its physical state. This significantly impacts your financing options and the property's liquidity.
Avoiding Fines and Municipal Sanctions: Peruvian municipalities are empowered to inspect properties. If they discover significant construction or renovations that are not duly declared and registered, the owner can be subject to substantial fines and even orders to demolish non-compliant structures. This can be a costly and time-consuming headache for a new owner.
Ensuring Property Value and Tax Basis: Property taxes (Impuesto Predial) are calculated based on the declared value of both the land and the constructions. If new construction is not declared, the official value of the property will be understated. While this might seem beneficial in the short term, it creates a discrepancy that must be rectified. More importantly, when you sell, the Alcabala (transfer tax) is assessed on the true sale price or cadastral value, whichever is higher. An undeclared structure means the base for tax calculation is inaccurate, potentially leading to later complications and higher tax burdens upon regularization.
Insurance Coverage: In the event of damage (e.g., from Arequipa's occasional seismic activity or other natural disasters), insurance companies may dispute claims related to structures that were not legally declared or properly permitted. This leaves your investment vulnerable and potentially uninsured for undeclared portions.
Addressing Ownership Disputes: A clear, registered Declaratoria de Fábrica strengthens your legal position against any potential claims or disputes regarding the property's improvements or boundaries. It provides an undeniable public record of the building's characteristics.

Step-by-Step for the Buyer: How to Verify the 'Declaratoria de Fábrica'

As a buyer, you are not responsible for obtaining the Declaratoria de Fábrica (that's the seller's responsibility), but you are absolutely responsible for verifying its existence and accuracy. This process requires meticulous attention to detail and professional assistance.

Necessary Tools:

Trusted Peruvian Real Estate Lawyer: Your primary guide and advocate. Essential for navigating Peruvian property law and performing comprehensive due diligence.
Independent Architect or Civil Engineer: Crucial for physically inspecting the property and comparing it against technical plans and legal declarations. Their objectivity is key.
Access to S.U.N.A.R.P. Online Portal (Consulta de Partidas): For real-time verification of property records.
Notary Public: The office through which public deeds are formalized and verified.
Patience and Due Diligence Mindset: This is not a process to rush.

Step-by-Step Verification Process:

Request Core Documents from the Seller:
- Copia Literal de Partida Registral: This is the certified history of the property from S.U.N.A.R.P. It will show all registered actions, including previous declarations of construction and any encumbrances. This is your most critical document.
- Declaratoria de Fábrica (Public Deed): Request the original or a certified copy of the public deed itself, where the declaration was formalized before a notary.
- Municipal Building Permits and Certificates of Completion (Constancia de Finalización de Obra): These documents prove the municipal authorization for construction and official completion, which precede the Declaratoria de Fábrica.
Preliminary Review of Documents:
- Match Seller's Identity: Ensure the seller's name on the Copia Literal matches their identification documents.
- Verify Declaratoria Registration: Check that the Declaratoria de Fábrica is clearly recorded in the Copia Literal, noting its date and public deed number.
- Compare Descriptions: Read the physical description of the property within the Declaratoria de Fábrica (or the Copia Literal) and compare it to the initial property listing and your understanding. Look for area, number of floors, distribution, and construction materials mentioned.
Cross-Reference with S.U.N.A.R.P. (Your Lawyer's Task):
- Your lawyer will use the Partida Registral number to directly access S.U.N.A.R.P.'s online system or visit the office to obtain a fresh Copia Literal. This ensures no recent changes or encumbrances have been missed and that the seller's provided documents are authentic and up-to-date.
- The Declaratoria de Fábrica should be clearly annotated in the Partida Registral, signifying its legal inscription and updating the property's legal description.
Physical Inspection by an Independent Expert:
- This is paramount. Hire an independent architect or civil engineer. Their role is to physically inspect the property and compare the actual construction against the plans and description contained in the Declaratoria de Fábrica and municipal permits.
- They will confirm if the dimensions, number of floors, layout, and extent of construction match the registered declaration. Any discrepancies here are major red flags that must be resolved by the seller. This step also serves as a crucial safety check against any unauthorized, non-compliant, or structurally unsound additions that could pose a risk, especially in Arequipa's seismic zone.
Legal Due Diligence by Your Lawyer:
- Your lawyer will perform a comprehensive review of all collected documents.
- They will confirm that the Declaratoria de Fábrica is properly constituted, registered, and free from any legal flaws.
- They will also ensure there are no pending municipal fines or orders related to undeclared construction that could transfer to you as the new owner.

Safety Checks:

"As Is" Warnings: Be extremely wary if a seller suggests you can "regularize" the Declaratoria de Fábrica after purchase. This indicates a problem they want to offload. The costs, time, and potential fines for post-purchase regularization can be substantial and unpredictable. Insist on a fully legalized property before closing.
Full Declaration: Ensure the Declaratoria de Fábrica accounts for all existing structures, including recent additions, annexes, or significant internal reforms. A partial declaration is still a problem and will cause future headaches.
Authenticity: Always verify documents directly with S.U.N.A.R.P. and the issuing notary, not just rely on copies provided by the seller.
Professional Expertise: Never attempt to conduct this due diligence on your own, especially as a non-native speaker unfamiliar with Peruvian legal intricacies. Professional assistance is not an option; it's a mandatory investment.

Local Context/Warning: Arequipa's Unique Considerations

Arequipa, with its rich history and status as a UNESCO World Heritage site, adds several layers of complexity to the Declaratoria de Fábrica process, especially for expat investors.

Historic Center Properties (Casonas): If you are considering a casona or any property within the historic downtown (e.g., near Yanahuara or directly in the historic core), renovations and new construction are subject to extremely strict regulations by the Ministry of Culture (Ministerio de Cultura) and the Municipality of Arequipa. Any Declaratoria de Fábrica for such properties must explicitly state compliance with these heritage preservation rules. Unauthorized alterations in these zones are a grave offense and can lead to severe penalties, demolition orders, and make future transactions virtually impossible. Always involve an architect specialized in heritage properties.
Growing Districts: Areas like Yanahuara, Cayma, and Cerro Colorado are experiencing significant growth, with many new apartment buildings and homes. While this signals development, it also means a higher chance of developers cutting corners or delays in formalizing the Declaratoria de Fábrica. Even in these desirable neighborhoods, thorough verification is critical. Assume nothing, and verify everything.
S.U.N.A.R.P. Arequipa: The local S.U.N.A.R.P. office on Calle La Merced (near the Plaza de Armas) is where all regional property registrations are handled. While much can be done online, your lawyer will likely interact directly with this office to ensure accuracy and resolve any specific queries.
Earthquake Preparedness: Arequipa is located in an active seismic zone. A properly issued Declaratoria de Fábrica (alongside the underlying building permits and Constancia de Finalización de Obra) provides a crucial degree of assurance that the construction adhered to mandated safety and engineering standards. An undeclared structure offers no such assurance and poses a significant risk to your safety and investment.
Informality vs. Legality: Peru has a history of informal construction. While the country is making strides in formalization, it's precisely why foreign investors must err on the side of extreme caution. As an expat, you are expected to navigate the legal system correctly, and informalities will expose you to disproportionate risks and costs.

Financial Implications and Taxes

Understanding the Declaratoria de Fábrica also has critical financial implications. For example, the Alcabala, or transfer tax, is levied on the higher of the property's sale price or its cadastral value. A properly declared construction will be reflected in the cadastral value. If you purchase an undeclared property and later regularize it, you might face an upward adjustment in future tax assessments and potentially penalties. The Alcabala is 3% of the sale value, after deducting a tax-exempt base (currently 10 Unidades Impositivas Tributarias - UIT, approximately PEN 51,500 or USD 13,800 as of 2024, converting at roughly 3.7 PEN/USD). An incomplete or absent Declaratoria de Fábrica can distort these calculations, leading to unexpected costs down the line.

Conclusion

The Declaratoria de Fábrica is far more than just another piece of paper; it is the legal bedrock for any newly built or significantly renovated property in Arequipa. For expats and foreign investors, it represents clarity, security, and the undisputed legal recognition of your investment. Neglecting its verification invites significant legal, financial, and administrative headaches that can easily outweigh any perceived initial savings. Always prioritize professional due diligence. Ensure that the property you fall in love with in Arequipa is as sound legally as it is physically.
