Post-intervention file when selling your home: when do you need one?

Post-intervention file when selling your home: when do you need one?

The post-intervention file when selling a home is a document many sellers only hear about when the notary asks for it. If you had work carried out by a contractor after 1 May 2001, you have to hand this file over to the buyer when you sell. This article explains what it contains, who draws it up and what to do if it is missing.

What is a post-intervention file?

The post-intervention file, often shortened to PIF, brings together the information needed to work on a building safely later on. Think of a plumber opening up a wall, a roofer replacing the roof or a contractor building an extension. Thanks to the file, they know where pipes and cables run, how the load-bearing structure is put together and which materials were used.

The obligation comes from the rules on temporary or mobile construction sites. These rules were introduced by the Royal Decree of 25 January 2001 and are now part of the Code on Well-being at Work. This is federal legislation. Unlike the EPC or the asbestos certificate, it therefore makes no difference whether your home is in Flanders, Wallonia or Brussels.

A PIF usually contains:

• the plans of the work as it was actually carried out, not just as it was designed;
• details of the structure and the load-bearing elements;
• the location of technical installations such as electricity, gas, water and ventilation;
• the materials used, with particular attention to materials that pose a risk, such as asbestos;
• the details of the contractors and designers involved.

When is a PIF required for a sale?

The rule is simple: for work that started after 1 May 2001 and was carried out by one or more contractors, a post-intervention file should exist. That applies to building a new home, but also to a major renovation, an extension or a new roof. When all or part of the building changes hands, the file has to be passed on to the new owner. The notary records this handover in the deed of sale.

If all the work on your home dates from before 1 May 2001, no PIF is needed. The notary will then usually include a clause in which you declare that no work requiring a file has been done since that date. If you did everything yourself, without a contractor, that generally falls outside the rules. If in doubt, run your situation past your notary.

The PIF does not stand alone. It is one of the documents you gather for a sale, alongside the EPC, the soil certificate and the electrical inspection, among others. You will find a full overview in our article on the documents you need to sell your home.

Who draws up the file and where can you find it?

If several contractors worked on the site at the same time or one after the other, a safety coordinator had to be appointed. The coordinator draws up the post-intervention file and hands it to the client, meaning you, at the end of the work. For smaller jobs with a single contractor there is no coordinator, and in practice the file is put together less rigorously. In that case, ask your contractor for the plans and the details of the materials used, so you can keep a complete file yourself.

Not sure where the file is? Start with the paperwork from the build or renovation, your architect or the safety coordinator. If you bought the home from someone who renovated it after 2001, the PIF should have been handed to you when you bought it. Your purchase deed states whether that happened.

For a flat, things work slightly differently. The file for the common parts, such as the roof, the facade or the lift, is kept by the property manager (syndic). For work inside your own unit, for example a new kitchen with changes to the pipework, you are responsible yourself.

What if the post-intervention file is missing?

A missing PIF does not mean you cannot sell your home. The sale goes ahead, but the notary will state in the deed that no file was handed over. For the buyer, that is a drawback: they lack information they will need for future work, and some buyers use it as a bargaining point.

You can also have a file put together after the fact. A safety coordinator or a specialised firm then collects the available plans, invoices and technical data and fills in the gaps where needed. The cost depends on the scale of the work and on what can still be found. Ask for a quote up front. Start in good time, because tracking down old plans and invoices often takes longer than drawing up the file itself. For an overview of what the various mandatory certificates cost, see our Dutch-language article on the cost of certificates when selling a house.

Be honest about what you know, too. If materials that pose a risk were used or found during work, that information should reach the buyer, with or without a PIF. Sellers who keep known problems quiet risk being held liable later on. Read more in our article on hidden defects when selling a home.

The PIF, the asbestos certificate and the planning permit

Sellers sometimes confuse the post-intervention file with other documents. They complement each other, but one does not replace another. In Flanders, the asbestos certificate is mandatory when selling a home built before 2001, regardless of whether any work was done later. The PIF covers precisely the work done after 1 May 2001. A home in Flanders may therefore need both documents. See also our article on the asbestos certificate when selling your home.

A planning permit is something else again. The PIF does not prove that the work was permitted, and a permit does not replace the PIF. If you renovated without the required permit, that is a separate issue best sorted out in advance. Our article on selling a house without a permit for a renovation covers it.

An experienced estate agent asks for these documents at the start of the sale, so there are no surprises at the sales agreement stage.

Frequently asked questions about the post-intervention file

Is a post-intervention file required when selling a home?

Yes, if work was carried out on the home after 1 May 2001 by one or more contractors. The file then has to be handed to the buyer at the sale, and the notary records this in the deed. No PIF is needed for older work.

Can I sell my house without a post-intervention file?

Yes. A missing PIF does not block the sale. The notary notes in the deed that no file was handed over. You can, however, have the file put together afterwards by a safety coordinator, which gives the buyer more clarity.

Who keeps the post-intervention file for a flat?

The file for the common parts of a block of flats is kept by the property manager (syndic). For work you had done inside your own flat, you are responsible for the file and for passing it on when you sell.

Does the post-intervention file apply throughout Belgium?

Yes. The PIF follows from federal rules on temporary or mobile construction sites, which are now part of the Code on Well-being at Work. The rule is the same in Flanders, Wallonia and Brussels.

Conclusion

The post-intervention file is a small document with a clear purpose: telling the next owner what is inside the walls, the floors and the roof. Look the file up as soon as you decide to sell, and have it completed if anything is missing. That way the sales agreement goes more smoothly and the buyer knows where they stand.
