Is my rent legal in Spain?
Whether your rent is legal depends on the town: in a declared zona tensionada a new long-term lease is capped — the rent can't exceed the previous contract's updated rent, and if the landlord is a large holder (gran tenidor) or the home wasn't let in the last five years, nor the official índex de referència ceiling — outside those areas there's no rent cap, but other tenant protections still apply.
Most of Barcelona and the Catalan coast are declared zones, so the caps bite there. The index ceiling is property-specific (size, condition, census section) — not a single number you can eyeball — and you can look it up for your exact address on the official tool.
If your rent sits well above the area's registered average in a capped zone, it may be unlawful and worth challenging.
