How to Buy Commercial Property in Castelldefels: A Practical Guide for Foreign Buyers

Buying a commercial property in Spain can be an excellent investment, whether you are planning to open a shop, office, restaurant, beauty studio, medical practice, or simply acquire a business premises as part of your long-term property portfolio.

For many international buyers moving to Castelldefels or Gavà Mar, commercial property can also support a broader relocation strategy: setting up a business, creating a rental structure, or securing a well-located asset close to Barcelona and the coast.

However, buying a commercial unit in Spain is not the same as buying a residential home. Before signing anything, it is essential to verify the legal status of the property, the tax treatment of the transaction, and whether the premises can actually be used for your intended business activity. In Spain, the Land Registry extract known as the Nota Simple is a key document because it shows the registered owner, description of the property, and registered charges or limitations.

Why buy a commercial property in Castelldefels or Gavà Mar?

Castelldefels is one of the most attractive coastal areas near Barcelona for international families, entrepreneurs, and investors. It combines year-round local demand, strong residential purchasing power, proximity to Barcelona Airport, and excellent connections to the city. Gavà Mar, meanwhile, attracts a premium international profile, making the wider area attractive for service-based businesses, lifestyle concepts, offices, and property-related operations.

For foreign clients relocating to the Barcelona coast, buying a commercial property in Castelldefels may be appealing for several reasons:

• long-term investment potential,

• the opportunity to operate your own business from the premises,

• demand for services aimed at expatriates and international residents,

• and strategic positioning in a high-quality coastal market near Barcelona.

Key documents needed to buy a commercial property in Spain

Before completion, the documentation should be reviewed carefully. In most cases, the purchase is formalised in a public deed before a notary, and then registered at the Land Registry. Spain’s registrars explain that the usual process is: sign at the notary, settle the applicable taxes, and submit the deed for registration.

The main documents and checks usually include:

1. Identification documents and NIE

Foreign buyers normally need an NIE number (Foreigner Identification Number) for the acquisition to be properly documented and registered.

2. Land Registry information and Nota Simple

The Nota Simple is essential. It provides an informative summary of the property’s registration details, including ownership, charges, mortgages, usufructs, and other limitations.

3. Cadastral data

The cadastral reference and physical description of the property should match the legal documentation and the actual premises.

4. Energy Performance Certificate

Commercial premises offered for sale generally require an Energy Performance Certificate.

5. Proof of tax status and community payments

You should verify whether there are any outstanding local taxes, community fees, or other obligations affecting the premises.

6. Corporate documentation, if a company is buying

If the buyer or seller is a company, additional corporate documents may be needed, including proof of representation and, where required, beneficial ownership information.

7. Occupancy and activity-related documentation

For a commercial unit, the legal analysis should focus less on residential occupancy documents and more on whether the premises can lawfully be used for the intended business. In Catalonia, if there is already an activity licence or prior communication in force, a change of ownership may need to be communicated to the Town Hall so the new holder takes over the related rights and obligations.

What to check before buying a commercial unit in Castelldefels

This is the stage where experienced guidance makes the biggest difference. A commercial purchase should never be based only on the asking price and location.

Check the legal ownership and charges

Make sure the seller is the registered owner and that the premises are free from unexpected charges, attachments, or mortgage-related issues. The Nota Simple is the first step, but it is not the only one.

Verify the permitted use of the premises

This is one of the most important issues for foreign buyers. A property may look ideal for a café, clinic, office, beauty salon, or retail concept, but that does not automatically mean the intended activity is permitted. In Catalonia, activity-related compliance can depend on the type of business and municipal procedures.

Review the tenant situation

If the property is sold with a tenant in place, review the lease, rent, deposit, term, renewal rights, and whether the tenant has any preferential rights.

Understand the building and community rules

For premises inside a larger building or complex, community statutes and regulations may affect signage, opening hours, extraction systems, terraces, or certain commercial uses.

Confirm the real acquisition cost

Beyond the purchase price, buyers must budget for taxes, notary fees, Land Registry fees, legal assistance, and possible adaptation works.

Reservation deposit and private purchase contract

In Spain, sellers often ask for a reservation deposit before taking the property off the market. This may be followed by a private purchase agreement setting out the price, parties, deadlines, and completion terms.

Before paying a deposit, it is wise to confirm at least the basic legal situation of the premises. That includes ownership, charges, and the tax treatment of the transaction. For registered real estate information, the Nota Simple is one of the main starting points.

Signing before the notary

The purchase is typically completed by signing a public deed of sale before a Spanish notary. The notary plays a central role in formalising the transaction and ensuring that the deed is legally structured. The notarial and registry framework in Spain is designed so that the deed can later be registered once the relevant taxes have been settled.

At this stage, the notary will verify identity and formal aspects of the transaction, while the legal and commercial due diligence should already have been carried out in advance.

Taxes when buying commercial property in Catalonia

The applicable taxes depend mainly on whether the sale is subject to VAT or Transfer Tax (ITP).

If the transaction is not subject to VAT

In Catalonia, property transfers that do not pay VAT are generally taxed under ITP. The Catalan Tax Agency explains that the general rate for urban real estate is 10% up to €600,000, with a progressive scale applying above that threshold. The rules apply broadly to urban immovable property, including commercial units.

If the transaction is subject to VAT

Where the transfer is subject to VAT, the deed may also trigger AJD if executed as a public notarial deed. The Catalan Tax Agency expressly states that when a real estate sale is taxed under VAT and formalised in a public deed, it also falls under AJD.

In commercial practice, new commercial premises are often associated with VAT, while many resale transactions fall under transfer tax instead, although the exact tax analysis depends on the seller’s status, whether the transaction is exempt from VAT, and whether any waiver of exemption is possible. The Spanish Tax Agency provides a real estate tax classifier precisely because this analysis can vary by case.

Registration after completion

After signing, the buyer must settle the relevant taxes within the legal deadline and then submit the deed for registration at the Land Registry. In Catalonia, the general filing and payment deadline for AJD self-assessment is one month from the date of the notarial document.

Land Registry registration is the final step that gives the new owner full registered protection. Spain’s registrars describe the standard sequence clearly: notary, taxes, then registration.

Typical costs to budget for

When buying a commercial property in Castelldefels or Gavà Mar, buyers should usually budget for:

• purchase tax or VAT, depending on the structure of the transaction,

• possible AJD,

• notary fees,

• Land Registry fees,

• legal due diligence,

• agency fees if applicable,

• and any refurbishment, compliance, or licensing costs needed before operating the business.

Frequently asked questions

Can a foreigner buy commercial property in Spain?

Yes. Foreign buyers can purchase commercial property in Spain, but they will usually need an NIE number and properly prepared documentation for the deed and registration.

Do I need to check the business licence before buying?

Absolutely. For a commercial unit, one of the most important checks is whether your intended business activity is already authorised, can be transferred, or will require a fresh municipal procedure. In Catalonia, change of ownership of an existing licence or prior communication may need to be formally notified.

Is a Nota Simple enough?

No. The Nota Simple is essential, but it is only part of the due diligence. It provides informative Land Registry data on ownership and charges, but it does not replace a full legal, tax, and practical review of the property.

Do commercial premises pay the same taxes as residential property?

Not always. The tax treatment depends on whether the transaction is subject to VAT or ITP, and commercial premises often follow different VAT rules from residential property. In Catalonia, when no VAT applies, urban real estate transfers generally fall under ITP; when VAT applies and the deal is executed in a public deed, AJD may also apply.

Should I buy in my own name or through a company?

That depends on your tax profile, business plan, financing structure, and long-term objectives. This should be reviewed case by case with a Spanish lawyer and tax adviser.
