Soil study for an aparta-estudio (studio unit) in Manzanillo del Mar: what to ask for before signing

The coast at Cartagena de Indias, Colombia

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 an aparta-estudio (studio 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.

An aparta-estudio, a single-room studio unit, is bought differently because it is the smallest unit in the tower, and that has consequences the floor plan does not show. Its coeficiente de copropiedad, the ownership share, is low, so its weight at the asamblea is low too; and in buildings made of identical units, decisions fall to whoever can assemble a crowd of small owners. Meanwhile several building costs are not shared by size but by occupancy: lifts, front desk, lobby, water, waste and wear on common areas all track how many people come and go, and a studio generates as much turnover as a large unit while contributing a far smaller share. The second consequence is the market. These units are bought almost entirely to rent out, so what the reglamento says about renting by the day is not a detail of use but a feature of the asset, since it defines who you can resell to. The third is physical: in a single room, kitchen, bathroom and ventilation share walls with neighbors, so whatever the copropiedad resolved about noise, extraction and quiet hours weighs more here than in a conventional apartment.

In Manzanillo del Mar the difficulty is not reading a registry record: often there is none to read. Much of what is offered never entered the registry at all, and what the counterparty holds is possession documented in private papers, with an acta de colindantes, a neighbors' boundary statement, and sometimes a sworn declaration before a notary, none of which is title of ownership. That moves the process to authorities absent in the other sectors: the Agencia Nacional de Tierras, the national land agency, where the soil belongs to the Nation; IGAC, the cadastral institute, and the district cadastre to identify the parcel; and the corregidor or the police inspector when occupation is disputed. Verification becomes a matter of fieldwork and mapping before notarial work: comparing the survey against the cadastral record and against what is actually fenced, because the same lot has been sold under different descriptions. The counterparty is usually a local family or a go-between with no written mandate, and that mandate has to be requested. Infrastructure is not handled by any single utility: a well or tanker water, a septic pit, and a side road whose upkeep is not always assigned to anyone.

What is specific to Manzanillo del Mar

A beach village north of Serena del Mar, where the original town still sits alongside the new complexes. A mixed market: social housing, beach condominiums and unserviced lots. Access is via the Manzanillo road off the Anillo Vial; the final stretch is not always paved to the same standard.

  • whether the lot is public wasteland of the Nation, in which case it is allocated rather than sold and no private deed can cure it
  • whether there is a right of way to the beach and where it runs, a constant source of litigation between neighbours
  • the land use the POT assigns it, because much of what is marketed as residential is still classified otherwise

What to verify, step by step

  1. Ask who signed the estudio de suelos and request the full report with its boring logs, not the cover sheet.
  2. 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.
  3. Ask Cardique whether the land is affected by mangrove, a water setback or a ciénaga, since that governs what can be founded there.
  4. Review what belongs to aparta-estudio units and is not covered by the report alone: whether the reglamento de propiedad horizontal allows daily rentals, since this is the unit type most often bought for exactly that and the ban never shows up in the brochure; whether the deed places kitchen and bathroom inside the área privada rather than treating them as shared services that cannot later be enclosed and how many identical units the tower holds, and what the administración rules about lift and lobby use by short-stay guests.
  5. Add what the ground in Manzanillo del Mar imposes: whether the lot is public wasteland of the Nation, in which case it is allocated rather than sold and no private deed can cure it; whether there is a right of way to the beach and where it runs, a constant source of litigation between neighbours and the land use the POT assigns it, because much of what is marketed as residential is still classified otherwise.
  6. 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 an aparta-estudio (studio 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.
