  • Things to Consider Before Undertaking a Renovation:

  • How to Renovate Your Home Without Problems, According to the OCU (Spanish Consumers' Organization) We know that unexpected issues always arise, but if you follow our advice, you'll minimize them. Here are 10 key points you shouldn't overlook when doing renovations in your home. 1. Don't improvise: consider all the implications. You know that the first thing is to think everything through. Carefully plan the work and consider when it will cause you the least disruption. Without falling into the "since I'm already doing it..." trap, think carefully about how you can make the most of things: if you're going to change the bathroom or kitchen floor, but the electrical wiring or pipes are old, it might be a good time to replace the old pipes, because that way you'll avoid having to tear up your new floor. 2. Who's doing the work? Before hiring anyone, get several quotes. You have three options:
  • Hire bricklayers, plumbers, electricians, carpenters, etc., separately. In theory, it will be cheaper, but you need meticulous planning and a minimum level of technical knowledge. If you don't have a plan, the result can be chaos.
  • Choose a contractor with their own team of workers.
  • Look for a company specializing in home renovations with an architect as advisor and project manager, and also consider "turnkey" companies. These are more expensive and will charge you for estimates. 3. Take accurate measurements. The estimates you receive will be based on the square or linear meters involved. Let the professional take the exact measurements, but double-check that they are correct. This ensures you won't be overcharged. 4. Be careful with structural elements. Make sure the work you plan doesn't affect any structural elements; this will prevent costly and difficult-to-repair damage. 5. Do you need a permit? Small projects don't require special permits, but sometimes a "responsible declaration" is needed. Check with your local council. It is mandatory to report any work that increases the living space, as this affects the property's cadastral value and the calculation of taxes such as property tax (IBI) or income tax (IRPF). 6. Community Approval: If you're working on common elements of the homeowners' association, you need the association's approval. Failure to do so could result in legal action, a work stoppage, or even a requirement to undo the work. Even if the work only affects your apartment, notify the president or the building manager. Tell them when the work will begin, how long it will last, and ensure that the stairs, elevator, and entrance hall are properly protected. 7. Do Everything Legally: Choose a reputable company with a tax identification number (NIF), bank account, and liability insurance. This way, if an accident occurs, you'll avoid unpleasant and costly problems. 8. Put Everything in Writing: Even if the work is small, it's advisable to have a signed document as proof in case of future problems or damage. A signed estimate from both parties can suffice, provided it includes the following information:
  • The company's address and tax identification number (NIF).
  • The start and end dates of the work.
  • The total price, including taxes, and the payment method.
  • The warranty period and how to file a claim. Specifically request a guarantee for the work.
  • A detailed description of the work and corresponding surfaces, the materials to be used with their specifications, and ideally, their brand and model if already decided.
  • The obligations they commit to for the work, such as cleaning the building entrance, repairing damages, etc. 9. Don't pay everything upfront. If they ask for a deposit, don't exceed 30-40% of the total. As phases are completed, you can make further payments, and when the work is completely finished, down to the smallest details, complete the payment. Ask for an invoice and always pay the VAT; it's an obligation as well as part of your guarantee for making claims if problems arise. 10. Check the VAT. The VAT applied should be 10% and not 21% if:
  • The client is an individual or a homeowners' association.
  • The work is for a dwelling used for private residence.
  • The property has been built or renovated for more than two years.
  • That the person carrying out the work does not provide materials for its execution, or if they do, their cost does not exceed 40% of the taxable base of the operation.
