Along this coast the ground is sand, fill and a high water table, and the foundation is the one part of a property you cannot see and cannot fix cheaply. The estudio de suelos —the geotechnical report— is the document that speaks to it, and what you should ask for depends on what you are buying.
A geotechnical engineer prepares the estudio de suelos with borings and laboratory testing, and it feeds the structural design filed with the licencia de construcción, the building permit. For a retail unit that turns into different questions: asking for the report that will support work not yet built is not the same as asking for the one that supported a building put up years ago. The report states what the exploration found and what foundation the engineer recommended; it does not certify that the work was built to that recommendation, it does not replace the environmental permit where mangrove, a water setback or a ciénaga is involved, and it does not assert that the property is sound today. Where no report exists, what remains is rebuilding the file: approved drawings, the filed permit, and the history of repairs the owners' association has voted.
A retail unit is bought differently because you are not buying a space but the possibility that someone can trade in it, and that possibility is granted by third parties. Two permissions are needed and nobody bundles them: the one the land-use rules give for that specific lot, and the one the copropiedad's reglamento gives, which need not agree. On top of those sit the tenant's own business permits, applied for activity by activity. The second difference is the relationship with the tenant. A lease of premises for commercial purposes runs under rules distinct from residential tenancies, with an expectation of continuity for the tenant that is worth having a lawyer spell out before signing, because the buyer steps into a contract that already exists and inherits its history. The third is that the unit depends on what lies outside it: façade, signage, pavement, loading area and public access are normally bien común, common property, or public space. What makes the unit profitable, in other words, is not inside its walls and is not decided from within the unit.
The procedural difference here is not the land but the building: almost everything is older, dense propiedad horizontal, the condominium regime, and the decision-maker is not the District but the owners' assembly acting through its bylaws. Buying means reading those bylaws before any brochure, reviewing recent assembly minutes, and asking the building manager for the paz y salvo, a no-arrears certificate, the approved budget and any special assessments, because a repair levy already voted passes to the buyer who never voted on it. Since the area lives on lodging, the registro nacional de turismo, the national tourism registry, joins in: the provider must be registered, the bylaws must permit that use, and the two must agree, because one is demanded by a national body and the other depends on the neighbors. The counterparty is usually an owner already renting the unit, sometimes through an operator under a live management contract, so establish what transfers with the property and what stays tied to the previous operator.
What is specific to El Laguito
The tip of Bocagrande, surrounded by water on almost every side and given over to visitor lodging since it was built. Older, very dense apartment towers, with much of the inventory given to short stays and apartment-hotels. The only way in is across Bocagrande along a narrow road that ends at the point, with no alternative exit.
- what the reglamento de propiedad horizontal, the condominium bylaws, say about renting by the night, since the assembly may have restricted it and that decides the business
- whether the unit and the building hold registro nacional de turismo entries, the national tourism registry, and in whose name, because the duty falls on whoever provides the service
- the condominium's accounts and pending lawsuits, along with façade and pipework upkeep in a building exposed to salt air
What to verify, step by step
- Ask who signed the estudio de suelos and request the full report with its boring logs, not the cover sheet.
- Confirm with the curaduría urbana —the private office that issues building permits— whether that report is in the permit file, and whether the approved drawings match what stands on site.
- Ask Cardique whether the land is affected by mangrove, a water setback or a ciénaga, since that governs what can be founded there.
- Review what belongs to retail units and is not covered by the report alone: whether the POT (the city's land-use plan) allows commercial use on that specific lot and whether the reglamento de propiedad horizontal admits it — two separate permissions, and you need both; whether the particular activity planned requires a concepto de uso de suelo (a land-use ruling) and who applies for it, owner or tenant and how façade, signage, pavement and loading area are allocated, since these are usually bien común even though the unit uses them daily.
- Add what the ground in El Laguito imposes: what the reglamento de propiedad horizontal, the condominium bylaws, say about renting by the night, since the assembly may have restricted it and that decides the business; whether the unit and the building hold registro nacional de turismo entries, the national tourism registry, and in whose name, because the duty falls on whoever provides the service and the condominium's accounts and pending lawsuits, along with façade and pipework upkeep in a building exposed to salt air.
- If no report exists because the building is old, commission an engineer to assess its present condition and ask the District for whatever risk information it holds on the property.
Mistakes that cost money
- Accepting the neighbouring lot's report. Exploration is site-specific, and in coastal fill it changes from one property to the next.
- Reading the report as a certificate that the building was properly built. It records what the engineer recommended, not what the builder did.
- Buying with a visible crack and a verbal promise that the administración will repair it. What counts is the minute in which the owners voted the work and how it is paid for.
Frequently asked questions
- Can the soil study for a retail unit be sent to me by email?
- Yes, it is a file and can be reviewed from abroad. The person who has to read it with judgement is an engineer, not the broker.
- What if the seller says the report was lost?
- Ask the curaduría for the permit file, where it was filed, and in parallel order an assessment of present condition.
- Does the soil study cover beach erosion?
- No. That is a separate question, put to the environmental and maritime authorities rather than to the geotechnical engineer.

- Cardique, autoridad ambiental del Canal del Dique — environmental permits, water setbacks and mangrove or wetland constraints
- Alcaldía Mayor de Cartagena de Indias — property tax, betterment levies and District procedures
