Comprehensive renovation in phases: how to plan the work and keep records

Before you start: define the real scope of the renovation

When an owner sets out to carry out a comprehensive renovation in phases, the most common mistake is to begin work without first having agreed the full map of the project. In a home within a residential community, it is not enough to think about the technical side; you must also consider which works affect common elements, what notices should be given and what documentation needs to be kept to evidence decisions, authorisations and progress.

The logic of a phased renovation is simple: divide the project into sections that are compatible with your availability, with life in the building and with document management. That does not mean improvising bit by bit. On the contrary, the better the sequence is planned, the less chance there is of repeating work, opening chases twice or losing useful receipts.

In addition, if the work affects installations, structure, enclosures, downpipes, service ducts, facades or any other element that is not exclusively private, coordination with the residents’ association stops being a practical matter and becomes a legal one. The Horizontal Property Act makes it clear that the owner may alter private elements only if this does not impair safety, structure, configuration or external appearance, or harm the rights of another owner, and that they must notify the works in advance to the person representing the community BOE.

How to organise a comprehensive renovation in phases

The most effective way to plan a renovation in stages is to turn it into a closed sequence of decisions. It is not just a matter of “doing the kitchen first and then the bathrooms”, but of fitting each phase into its technical and documentary logic.

1. **Set the purpose of each phase.** Decide what each stage is meant to achieve: demolition, installations, partition walls, finishes, joinery or final touches. If you do not define the objective, it is easy to mix incompatible items.

2. **Separate private from common elements.** Identify what only affects your home and what may touch slabs, facades, courtyards, downpipes, shunts, ventilation or shared elements.

3. **Prepare a dependent sequence.** Some works require another phase to be completed first. For example, it is not advisable to close walls if installations or tests are still outstanding.

4. **Review access for tradespeople and materials.** In residential buildings, logistics matter: timings, lift use, protection of common areas, waste removal and access to the property.

5. **Create a single project folder.** This should hold plans, quotes, notices, authorisations, minutes, certificates and photographs of before, during and after.

### Practical tips to keep the works under control

- Put in writing what each phase includes and what it does not include.

- Ask the technician or contractor for a clear breakdown of the works so you can track progress.

- Take dated photographs before starting, especially of service routes and areas that will later be hidden.

- If you expect several pauses between phases, note the state of the works when each stage is closed.

- Keep all versions of plans or relevant changes; sometimes the important document is precisely the one that replaced an earlier one.

Permits, the residents’ association and notices that it is worth getting in order

In a comprehensive renovation carried out in phases, one of the key points is knowing when a simple notice is enough and when a community agreement or more careful review may be needed. The Horizontal Property Act states that the owner must give prior notice of the works and may not alter the rest of the property or carry out actions that harm other owners BOE.

It is also worth remembering that the owners’ meeting has authority over approving budgets and carrying out repair works on the property, whether ordinary or extraordinary, and over other matters of general interest BOE. For that reason, if your renovation may affect common elements or the organisation of the community, do not leave the notice until the end.

Recommended steps:

1. **Check the title deeds, rules and internal regulations if they exist.** Not to turn the work into a dispute, but to identify any existing limits on use, noise, timings or works affecting common elements.

2. **Prepare a brief, clear notice.** It should explain what works you will do, in what phases, over what approximate periods and whether you expect temporary occupation of common areas.

3. **Keep a copy of everything sent.** If you hand documentation to the chair, the administrator or the secretary, keep proof of delivery or acknowledgement of receipt.

4. **Ask in writing for any authorisation or approval you receive.** An informal conversation may help, but it does not replace a clear document.

5. **If there is a disagreement about the nature of the works, request a technical review.** Article 17 allows the owners’ meeting to decide in the event of disagreement about the nature of the works, and also allows those concerned to request arbitration or a technical opinion BOE.

What documents you should keep from day one

Renovation paperwork is not kept simply “just in case”; it is kept because it may be needed to justify what has been carried out, explain a later change or prove that you followed the community’s internal procedures.

You should file, at a minimum:

- Quotes received and the final accepted version.

- Contracts or commissions with technicians, contractors and suppliers.

- Notices to the residents’ association and any responses received.

- Minutes or extracts of agreements affecting the works.

- Photographs of the initial condition and the final condition.

- Certificates for works carried out, if any.

- Manuals, guarantees and technical data sheets for installed equipment.

- Proof of incidents, repairs or changes in scope.

The secretary of the community must keep the minute books and retain, for five years, the notices, communications, powers of attorney and other relevant meeting documents BOE. The administrator, for their part, must keep the community’s documentation available to the owners BOE. This is useful to you as an owner because, if you need to reconstruct what was discussed or agreed, you will know where to request the information.

### Common mistake

Do not rely on keeping only loose mobile messages or unorganised emails. If one day you need to prove what was authorised, what was communicated or which phase was still pending, a chaotic folder makes verification much harder.

How to set up a useful file for the whole renovation

A simple system usually works better than a perfect but incomplete file. The important thing is that you can find any document within seconds.

1. **Create a master folder for the property.**

2. **Inside it, separate by phases.** For example: demolition, installations, finishes and closure.

3. **Add a community subfolder.** This should contain notices, replies and agreements.

4. **Store dated versions.** If a plan or technical solution changes, do not delete the earlier one.

5. **Include a final summary.** When finished, write down what was done and what was left prepared for future works.

If you would like to assess the overall condition of your home before starting or after finishing, you can request an indicative estimate at /valoracion-vivienda-madrid. It is not an official valuation, but it can help you organise the starting point or the final result.

When it is worth asking for professional support

Some renovations can be organised with basic management, while others require more technical control. If the works affect structure, general installations, enclosures or common areas, or if you expect the residents’ association to raise objections, it is advisable to have professional advice from the outset.

It is worth asking for help if:

- You are not sure whether a work affects a common element.

- There are doubts about what should be communicated to the residents’ association.

- There are several phases and you are worried about losing documentary traceability.

- The works depend on prior decisions by the building.

- You need to organise the information for future transfers, insurance or incidents.

If you would like to review your case in more detail, you can write to /contacto or visit the office at Montesa 29, Madrid, Monday to Friday from 10:00 to 15:00 and from 16:00 to 19:00.

In short, a comprehensive renovation in phases works better when you plan like an owner and document it as if you had to explain it tomorrow: a closed scope, clear notices, an organised file and follow-up of each stage. That discipline avoids mistakes and gives you room to manoeuvre if the residents’ association needs clarification or if, later on, you want to prove what was done and why.
