Medellin rentals and the estrato system explained

Every rental listing in Medellín mentions a number from 1 to 6. That number is the estrato, the socioeconomic stratum assigned to the property, and it affects how much you pay for water, power and gas every month. Americans often read it as a neighborhood rating. It is something narrower: a classification used to set public utility tariffs. Understanding it, and the national rental law that applies to every lease, helps you compare apartments in El Poblado, Laureles, Envigado or anywhere else in the Aburrá Valley.

What the estrato is

DANE, Colombia's national statistics office, defines socioeconomic stratification as the classification of residential properties into groups, carried out mainly to charge household public services differentially by stratum and to assign subsidies and contributions. The classification applies to the dwelling, based on its physical characteristics and its surroundings, not to the income of the people who live in it.

DANE lists six strata:

• Estrato 1: low-low
• Estrato 2: low
• Estrato 3: medium-low
• Estrato 4: medium
• Estrato 5: medium-high
• Estrato 6: high

How it changes your bills

The system works as a cross-subsidy. According to DANE, households in strata 1, 2 and 3 receive subsidies on their public service bills, stratum 4 pays the cost of the service, and strata 5 and 6 pay a contribution on top of the cost that helps fund the subsidies. The same consumption of electricity or water therefore costs more in a stratum 6 apartment than in a stratum 3 apartment.

For a renter this has three consequences:

1. Utilities vary with the stratum, not only with use. Ask for recent utility bills when you view an apartment, and compare totals rather than rent alone.
2. Higher strata come with higher bills. A stratum 5 or 6 apartment in a district such as El Poblado can have noticeably higher utility costs than a similar flat in a stratum 3 or 4 area.
3. Commercial properties are treated separately. Stratification applies to residential properties.

Medellín's main utility company bills water, sewage, power and gas, and the bill shows the stratum of the property.

How to check a property's stratum

The Alcaldía de Medellín issues an official certificate of socioeconomic stratification for residential properties in the municipality. According to the city's procedures page, the certificate can be requested fully online with an immediate response, and the online request is free. In person, the city charges a small fee. The request identifies the property through documents such as the nomenclature certificate, a property tax statement or a previous stratum certificate, and the utility bill or meter number.

If you believe a property's stratum is wrong, the owner can request a correction from the city. The city's page for that procedure lists a response time of 60 business days. For a tenant, the practical step is to ask the landlord for a recent utility bill, which shows the stratum.

What the estrato does not tell you

• It is not a safety rating. Security varies street by street. Visit at different times of day.
• It is not a rent cap. Rents are set by the market, not by stratum.
• It is not a measure of building quality inside. Two apartments in the same stratum can be very different in age, maintenance and amenities.

The rental law that applies to every lease

Residential leases in Colombia are governed by Law 820 of 2003. Several of its rules matter for foreign tenants.

Rent increases. The rent can be raised once every twelve months of execution of the contract. The increase cannot exceed 100 percent of the change in the consumer price index (IPC) for the previous calendar year. DANE reported annual inflation of 5.10 percent for December 2025, so a lease renewing in 2026 could rise by at most that percentage. The law also caps the monthly rent at 1 percent of the commercial value of the property.

Deposits. Law 820 prohibits requiring cash deposits or similar guarantees from the tenant as security for the obligations of the lease. Landlords and agencies use other guarantees instead, such as co-signers (codeudores) or policies issued by guarantee companies.

Written contracts. Article 3 allows a lease to be verbal or written, but a written contract makes disputes easier to resolve. Read it in full before you sign, including the duration, the notice period for leaving and who pays the building administration fee.

Building administration fees

Most apartment buildings in Medellín charge a monthly administration fee (cuota de administración) for shared services such as security staff, cleaning, elevators and common areas. Listings usually say whether the rent includes it. Ask which amenities the fee covers and whether there are planned special charges.

Furnished and short-term rentals

Medellín has a large market of furnished apartments rented by the month to foreigners. These often include utilities and internet in the price and may be offered without the guarantees a traditional lease requires. Compare the total monthly cost with an unfurnished long-term lease plus utilities, and read the terms carefully: a short-term furnished rental is not always covered by the same contract conventions as a standard Law 820 residential lease.

Neighborhoods foreigners often consider

Americans looking in Medellín commonly compare El Poblado, Laureles-Estadio, Belén, Envigado and Sabaneta. Each area includes properties in several strata. Visit in person, test the commute to where you will work or study, and walk the streets in the evening. The metro and the bus network connect most of the valley, and the Cívica card pays for them.

Paperwork landlords ask for

A traditional lease through an agency usually asks for:

1. Your identity document. A Cédula de Extranjería makes the process easier than a passport.
2. Proof of income, such as employment letters, bank statements or pension certificates.
3. One or two co-signers, or approval from a guarantee company.

Some agencies will not process applicants without a Colombian credit history. Furnished monthly rentals are a common first step while you establish one.

Checklist before signing

• Ask for the latest utility bills and confirm the stratum on them.
• Confirm the administration fee and what it covers.
• Check the lease duration and early termination terms.
• Note the start date for the 12-month increase rule.
• Photograph the apartment's condition on move-in day and attach an inventory to the contract.

Common questions

What does estrato mean in a Medellín rental listing? It is the property's socioeconomic stratum from 1 to 6, used to set utility tariffs. Strata 1 to 3 get subsidies, 4 pays cost, and 5 and 6 pay a contribution above cost.

How much can my landlord raise the rent in Colombia? Under Law 820 of 2003, once every 12 months and by no more than the previous year's consumer price index change. DANE reported 5.10 percent for 2025.

Can a Colombian landlord ask for a cash deposit? Law 820 of 2003 prohibits cash deposits as security for a residential lease. Landlords use co-signers or guarantee company policies instead.

How do I check a property's official stratum in Medellín? The Alcaldía de Medellín issues a stratification certificate online, free and with an immediate response. A recent utility bill also shows the stratum.
