Bylaws with 'residential or office use': your apartment cannot be a short-term rental

Key data

If you own an apartment in a community whose bylaws only contemplate residential or office use, your investment in short-term rental may be blocked before you even start. The Resolution of 27 March 2026 from the DGRSJFP, published in the BOE on 9 July 2026, confirms that the bylaw clause "apartments must be dedicated to residential or office use" is sufficient to prevent the registration of the unique short-term rental number.

This is not a new prohibition: the resolution consolidates a criterion already advanced in a previous resolution from June 2025. What is relevant now is that it is established as applicable property registry doctrine throughout the territory.

What does this regulation establish?

The specific case arises in Zaragoza. A property owner requested the Property Registry no. 2 to assign the unique registration number for short-term tourist rental for his apartment. The registrar suspended the assignment because the community bylaws established that apartments could only be dedicated to "residential or office use".

The property owner appealed with two arguments:

• The bylaws do not expressly prohibit tourist use.
• The community itself submitted the prohibition of short-term rental to a vote, which —according to the appellant— implies that it was not previously prohibited.

The DGRSJFP dismissed the appeal and confirmed the property registry qualification. Its reasoning is clear: the limitation to "residential or office use" excludes short-term tourist rental because this use does not equate to permanent residential use. An express prohibition is not necessary; it is sufficient that tourist use is not included among the permitted uses.

Economic and operational impact

The impact is direct for any property owner or investor who has acquired or is considering acquiring an apartment for short-term rental in a community with similar bylaws:

• Inability to obtain the unique registration number for short-term tourist rental, an essential requirement to operate legally in most autonomous communities.
• Property registry blockade without requiring a vote at the assembly: the community does not need to approve any additional agreement; existing bylaws are sufficient.
• Risk in purchase and sale operations: an apartment acquired with the expectation of allocating it to short-term rental may become unfeasible if the bylaws contain restrictive use clauses.
• Opportunity cost: the difference in profitability between long-term residential rental and short-term tourist rental can be very significant in areas of high tourist demand.

This criterion consolidates and expands the scope of the previous resolution from June 2025, which means that the doctrine is no longer provisional: it is established property registry doctrine.

Who does it affect?

• Apartment owners in communities whose bylaws limit use to "residential", "residential use" or "office", who want to allocate them to short-term rental.
• Real estate investors who operate or plan to operate in the short-term rental segment (Airbnb, Booking, similar platforms).
• Funds and patrimonial companies with portfolios of apartments in buildings with restrictive bylaws.
• Real estate advisors and property agents who must inform their clients about the viability of tourist use before a purchase and sale.
• Vacation rental managers who administer apartments in communities with this type of bylaw clauses.
• Communities of property owners who want to understand the scope of their own bylaws without needing to call an assembly.

Practical example

An investor acquires an apartment in a building in Zaragoza with the intention of operating it as a tourist apartment. Before formalizing the purchase, he does not review the community bylaws. The bylaws, drafted decades ago, establish that "apartments must be dedicated to residential or office use".

When requesting the Property Registry to assign the unique registration number for short-term tourist rental —a mandatory step to operate legally—, the registrar suspends the assignment. The investor appeals arguing that the bylaws do not expressly prohibit tourist use, but the DGRSJFP dismisses the appeal: the limited use clause is sufficient to block the registration.

Result: the investor cannot operate the apartment as a short-term rental without first modifying the community bylaws, which requires unanimity of all property owners according to the Horizontal Property Law. If any neighbor opposes, the blockade is definitive.

What should property owners do now?

1. Review the community bylaws before any operation. Request a simple note from the Property Registry or ask the property manager for the bylaws. Look for any clause that limits use to "residential", "residential use" or "office".
2. If you already have an apartment in tourist operation, verify your property registry situation. Check if you have the unique registration number correctly assigned. If there are doubts, consult with a lawyer specializing in horizontal property.
3. If you are considering a purchase for tourist use, include bylaw review in the due diligence. A restrictive use clause can make the project unfeasible without possibility of appeal.
4. If you want to modify the bylaws to allow tourist use, prepare for a unanimity process. The Horizontal Property Law requires the unanimous agreement of all property owners to modify bylaws. Assess the real viability before starting the process.
5. Inform your clients if you are a real estate advisor or agent. This property registry criterion is consolidated doctrine since the June 2025 resolution and confirmed in July 2026. Failure to inform can generate professional liability.
