Cartagenaculture & etiquette

Cartagena taxis do not run meters and never have. The fare is negotiated or assumed by zone, which means every ride is a small price discovery exercise and foreigners routinely pay two or three times the local rate. Ask a Colombian colleague or your building's portero what a given trip should cost, state your price rather than asking theirs, and default to Uber, DiDi or InDrive where the fare is fixed in the app. This is the single most common way newcomers quietly overpay every single day.

Cartagena sits at sea level and runs at 28–32°C with humidity above 80% for most of the year. Air conditioning is not a luxury and running it is the largest variable in your monthly costs. Layer on the estrato: every dwelling carries a 1-to-6 rating attached to the property, and estratos 5 and 6 pay a solidarity surcharge on utilities — capped at 20% of the service value for electricity and piped gas by Ley 142 de 1994 art. 89.1, but much heavier on water, sewerage and rubbish, where Ley 1450 de 2011 art. 125 sets floors of 50% for estrato 5 and 60% for estrato 6. A Bocagrande flat with aircon running all day is a different financial proposition from the same flat in Manga. Ask for an Afinia bill from a hot month, not an average.

Short-term tourist letting in Colombia requires registration in the Registro Nacional de Turismo, and in an apartment building the horizontal-property by-laws must expressly permit the provision of accommodation. Administrators can and do report unauthorised units, and the Superintendencia de Industria y Comercio enforces. A draft decree circulating in 2026 would push platforms to verify hosts' registrations every six months and delist those without one. If part of your plan is to buy in Cartagena and let it out, read the building's reglamento before you read the listing.

The Centro Histórico is a national heritage asset and the IPCC's rules prohibit visible air conditioning units, water tanks and antennas on external elevations, and prohibit perforating walls, doors, windows and façades to fit air conditioners or extractors. That is a genuine constraint on a colonial house in a city this hot, and it also complicates satellite dishes and some external cabling. A new Plan Especial de Manejo y Protección was approved by the National Council of Cultural Heritage in June 2026 and awaits its ministerial resolution; until it is formally in force, ask precisely who authorises what before you commit to any works.

Sea air corrodes everything: hinges, laptop ports, bicycle chains, air conditioning coils, car bodywork. Humidity above 80% grows mould in wardrobes and behind furniture within weeks if a flat is shut up. Run the aircon or a dehumidifier periodically even when away, leave air gaps behind furniture, and expect to service split units more often than the manual suggests. In older Getsemaní and Centro houses, ask specifically about damp in the walls before you sign.

Cartagena restricts private cars only in the two peaks — roughly 7am to 9am and 6pm to 8pm — while motorcycles are restricted from 5am to 11pm on their day. The digit-to-weekday table changes every few months rather than every six, so it is not a rule you memorise once. Weekends and public holidays are exempt. Given the short car windows and the traffic through the centre, most residents drive little and walk, take TransCaribe or use apps.
