Key takeaways
- The coefficient is a percentage assigned to each unit when the building was constituted, not a simple ratio of square meters.
- The reglamento may restrict a "local comercial" to retail and ban restaurants, bars, extraction ducts, late hours or deliveries.
- Closing takes 30 to 45 days, enough to read every acta.
- Long-term rentals have yielded 5 to 9 percent gross a year, before administración, property tax, vacancy and repairs.
- The registry number and the certificate of tradition and freedom (registered owner, mortgages, liens, encumbrances); delivery free of administración debt; seller responsibility for extraordinary cuotas approved before signing; and confirmation that the reglamento's permitted use matches yours.
A commercial unit in Medellín is a horizontal property unit like any apartment, so the administración is charged against a coefficient written in the reglamento, not against your sales or your floor area alone. Verify three things before you sign: the coefficient, the budget line for the commercial zone, and whether the building bills extraordinary cuotas separately.

Why does the commercial unit pay more than an apartment of the same size?
The coefficient is a percentage assigned to each unit when the building was constituted, not a simple ratio of square meters. In mixed-use buildings ground-floor commercial units often carry more than their area suggests: frontage, separate entrances, independent services and signage rights push it up. It sets both your share of monthly administración and your voting weight in the asamblea, a liability and a right at once. Find the coefficient table in the reglamento de propiedad horizontal and multiply your percentage by the approved annual budget for the real annual cost.
What should I ask the administrador for before I make an offer?
- The reglamento, with the coefficient table and the clause on use of common areas.
- The approved budget, by line, to see what the commercial zone consumes.
- Paz y salvo de administración. Unpaid cuotas follow the unit, not the seller.
- Actas of the last two or three asambleas, the most revealing: a building arguing about a leaking parking deck is about to bill you for it.
- Any approved extraordinary cuota and its payment calendar.
- The reserve fund balance, which shows whether the next big repair is a surprise bill.
Can the building stop me from running the business I want?
Yes. The reglamento may restrict a "local comercial" to retail and ban restaurants, bars, extraction ducts, late hours or deliveries. The municipal territorial plan sits on top, and both must say yes; check the reglamento first, since it fails more often. Many reglamentos also treat the facade as common area, so signs, awnings, lighting and window vinyl need asamblea approval.
How do extraordinary cuotas and the reserve fund actually hit me?
Extraordinary cuotas are voted in the asamblea, charged on the same coefficient and enforceable against the unit; if one was approved before you bought, you inherit the remaining instalments. A funded reserve absorbs an elevator replacement quietly; an empty one passes it to owners, which for a heavy-coefficient unit can be several months of rent. Put the paz y salvo and extraordinary cuota status in the promesa de compraventa, with the seller responsible for anything approved before signing. Closing takes 30 to 45 days, enough to read every acta.
How does the coefficient change the yield math?
Long-term rentals have yielded 5 to 9 percent gross a year, before administración, property tax, vacancy and repairs. Take the asking rent, subtract the real administración from coefficient and budget, subtract property tax (0.3 to 1.2 percent of the cadastral value annually), then compare. Buyer closing costs run about 2 percent (notary 0.27 percent, registry 0.67 percent, beneficencia 1 percent), plus your lawyer; capital gains are 15 percent when held two years or more. Two units at the same price and rent are not the same investment if one carries double the coefficient. For the rest of the sequence, see the full guide.
What goes in the promesa de compraventa?
The registry number and the certificate of tradition and freedom (registered owner, mortgages, liens, encumbrances); delivery free of administración debt; seller responsibility for extraordinary cuotas approved before signing; and confirmation that the reglamento's permitted use matches yours. If the unit comes with parking or storage, confirm whether they are separate registry numbers with their own coefficients or common areas of exclusive use.
Frequently asked questions
What is the coefficient in a Colombian horizontal property building?
A percentage assigned to each unit in the reglamento. It sets your share of administración and your voting weight; multiply it by the approved annual budget for your annual cost.
Do unpaid administración fees transfer to the new owner?
The debt follows the unit. Get a paz y salvo before closing and make pre-signing extraordinary cuotas the seller's responsibility in writing.
Can a building's rules block a business that municipal zoning allows?
Yes. The reglamento can prohibit restaurants, bars, ducts, late hours or deliveries even where the plan permits them.
Do I need approval to put up a sign on my commercial unit?
Usually yes, since most reglamentos treat the facade as common area.
How long does it take to close on a commercial unit?
30 to 45 days once the deal is agreed.
