Plenty of coffee shop projects die not from a lack of customers, but from two permits that get sorted out far too late: the extraction flue and the terrace licence. By the time the problems surface, the deposit has been paid, the fit-out has begun and, in some cases, a lease transfer has already been signed. The golden rule is simple: don't sign anything until you have first confirmed that, in that specific property, you can actually do what you intend to do.
The first fundamental mistake is believing that in Spain "you can open a bar almost the same day". Bars, coffee shops and restaurants were left out of the national liberalisation of retail trade (Ley 12/2012), so how quick the process is depends on regional legislation and the municipal ordinance, not on a single national rule. In Valencia, for example, the Responsible Environmental Declaration (Declaracion Responsable Ambiental) imposes a wait of up to a month; opening on the same day only applies to genuinely harmless activities.
If you're going to do hot cooking, extraction gets complicated. The technical standard requires venting through the roof, one metre above the highest point of the roof, with minimum distances to windows, balconies and air intakes. And there's one detail that derails entire projects: running the ducting up the facade, through a courtyard or across the roof requires authorisation from the residents' association (comunidad de propietarios), and the building's statutes may prohibit it outright. A "no" from the neighbours can leave the premises unusable for a kitchen.
On top of that, from June 2026 the extraction requirements are being tightened (filters that capture 95% of grease, motors certified for high temperatures, insulation on ducts that pass through communal areas), with penalties that can range from 6,000 to 50,000 euros. Installing an extraction flue runs to around 3,000-6,000 EUR in small premises and can shoot up to 12,000-25,000 EUR in complex cases. In Barcelona, the C1/C2/C3 classification determines whether you need a chimney: a coffee shop with no on-site cooking (C1) often escapes it.
A terrace is tempting because it can lift turnover by 20-30% without touching the rent. But it occupies public land, so it requires its own licence with an express resolution -a responsible declaration won't do- plus payment of a fee. In Madrid the resolution can take three to six months, and the terrace fee for the top categories runs to around 74 EUR/m² per season. Counting on those square metres before they've been approved means planning around something that may never arrive.
And there are areas where a terrace simply isn't possible. Madrid has Special Acoustic Protection Zones (Centro, Ponzano, Arapiles, the area around Ibiza street...) where setting up new hospitality terraces is prohibited; Barcelona has declared similar protections in Ciutat Vella, Sarrià-Sant Gervasi and Horta-Guinardó.
Before buying or renting, it's wise to ask the town hall in writing for a planning compatibility certificate (certificado de compatibilidad urbanística): it confirms whether hospitality use is permitted in that specific property. If the use isn't compatible, no fit-out or project can fix it. And if the premises weren't previously used for hospitality (they were a shop, an office or a warehouse), the change of use usually requires a full activity licence with a project.
A lease transfer (traspaso) is usually someone else's failure, so genuine bargains are rare. Depending on the legal arrangement, you may inherit debts with suppliers, the tax authorities or Social Security, along with licences carrying restricted hours or disputes with the neighbours. Before you pay, dig into why it's being transferred at the town hall: planning history, type of licence, works permits and debts. In Madrid, a hospitality lease transfer can range from 30,000 to 200,000 EUR and more than double your total investment.
As one coffee shop owner sums it up: "you can easily blow 50,000 euros without having so much as pulled a single coffee". The right sequence protects that money: validate extraction, terrace and planning compatibility before signing, and only then start the fit-out. Walking away from a set of premises hurts far less than discovering the problem once the works are already done.
