The Exact Process for Obtaining a Certificate of Structural Fitness from LASBCA for Older Buildings in Lagos Island

The Exact Process for Obtaining a Certificate of Structural Fitness from LASBCA for Older Buildings in Lagos Island

Lagos Island is home to some of Nigeria’s oldest commercial and residential buildings. Areas such as Marina, Broad Street, Campos, Balogun, Idumota, Ebute Ero, Isale-Eko, Onikan, and parts of Adeniji Adele contain numerous structures that have been standing for several decades. While many of these buildings continue to serve commercial and residential purposes, ageing, increased occupancy, unauthorized structural alterations, poor maintenance, coastal weather exposure, and heavy traffic vibrations can all affect their structural integrity over time.

To improve public safety and reduce the risk of building collapse, the Lagos State Building Control Agency (LASBCA) carries out post-construction audits, monitors distressed buildings, and issues structural-related certifications where buildings satisfy applicable requirements. Older buildings seeking certification are generally required to undergo a Structural Stability and Integrity Test conducted by qualified professionals before LASBCA considers issuing the relevant certificate or approving continued use. (LASBCA)

This guide explains the practical process involved in obtaining a Certificate of Structural Fitness (or structural fitness clearance) for older buildings in Lagos Island.

What Is a Certificate of Structural Fitness?

A Certificate of Structural Fitness is evidence that a building has undergone structural assessment and has been found suitable for continued occupation or use, subject to any conditions imposed by the relevant authorities.

For existing buildings, LASBCA relies heavily on a Structural Stability and Integrity Test Report prepared by qualified professionals as part of its assessment process. For completed developments, this forms part of the documentation considered before issuing a Certificate of Completion and Fitness for Habitation/Use, where applicable. (LASBCA)

Why Older Buildings Require Structural Assessment

Older buildings may experience:

  • Concrete deterioration.
  • Steel reinforcement corrosion.
  • Foundation settlement.
  • Structural cracking.
  • Water ingress.
  • Overloading due to change of use.
  • Damage from unauthorized renovations.

A professional structural assessment helps determine whether the building remains safe.

Buildings That Commonly Require Structural Certification

The process is particularly relevant for:

  • Commercial buildings.
  • Multi-storey residential buildings.
  • Mixed-use developments.
  • Institutional buildings.
  • Buildings undergoing major renovation.
  • Buildings changing from residential to commercial use.
  • Structures identified by LASBCA during inspections.

Step 1: Engage Qualified Professionals

The building owner should engage appropriate consultants, including:

  • A COREN-registered Structural Engineer.
  • A Registered Builder where necessary.
  • An Architect.
  • Other specialists if required.

The structural engineer will coordinate the technical assessment.

Step 2: Gather Existing Property Documents

Prepare available documentation, including:

  • Certificate of Occupancy or other title documents.
  • Approved building plans (if available).
  • Survey plan.
  • Previous renovation approvals.
  • Structural drawings (if available).
  • Maintenance records.

Older buildings may not possess complete historical records, but every available document should be assembled.

Step 3: Carry Out a Structural Stability and Integrity Test

A detailed structural investigation is conducted.

This typically includes:

  • Visual inspection.
  • Crack mapping.
  • Foundation assessment where accessible.
  • Inspection of beams.
  • Inspection of columns.
  • Inspection of slabs.
  • Roof structural assessment.
  • Review of signs of settlement.

The engineer may also recommend laboratory or non-destructive testing where appropriate.

LASBCA’s published guidance specifically identifies a Letter of Structural Stability and Integrity Test as a required document for older existing buildings in relevant certification processes. (LASBCA)

Step 4: Conduct Material Testing (Where Necessary)

Depending on the building’s condition, further investigations may include:

  • Concrete strength testing.
  • Reinforcement location surveys.
  • Cover measurements.
  • Corrosion assessment.
  • Foundation investigations.
  • Geotechnical studies.

The exact testing programme depends on professional engineering judgment.

Step 5: Prepare the Structural Report

The consulting structural engineer prepares a report covering:

  • Description of the building.
  • Inspection findings.
  • Test results.
  • Structural analysis.
  • Observed defects.
  • Recommended repairs (if any).
  • Professional opinion on structural stability.

Step 6: Rectify Identified Defects

If deficiencies are found, remedial work may be required before certification.

Examples include:

  • Crack repairs.
  • Concrete repairs.
  • Reinforcement treatment.
  • Structural strengthening.
  • Roof repairs.
  • Foundation stabilization.

Major repairs should be supervised by qualified professionals.

Step 7: Submit Application to LASBCA

The owner or appointed consultant submits the necessary application and supporting documentation to LASBCA.

Depending on the circumstances, documentation may include:

  • Application letter.
  • Structural Stability and Integrity Report.
  • Consultant’s covering letter.
  • Title documents.
  • Approved drawings where available.
  • Evidence of payment of applicable fees.
  • Other documents requested by LASBCA.

Requirements may vary according to the nature and history of the building. (LASBCA)

Step 8: LASBCA Technical Review

LASBCA reviews the submitted documentation to determine whether additional information or corrective measures are required.

The Agency’s mandate includes identifying distressed buildings, monitoring structural safety, and enforcing building control standards. (LASBCA)

Step 9: Physical Inspection by LASBCA

LASBCA officers may inspect the property to verify:

  • Structural condition.
  • Compliance with submitted reports.
  • Evidence of repairs.
  • General safety.
  • Overall building condition.

Inspection findings form part of the Agency’s evaluation.

Step 10: Address Any Compliance Issues

If inspectors identify concerns, the owner may be required to:

  • Carry out additional repairs.
  • Submit revised engineering reports.
  • Provide further documentation.
  • Complete outstanding compliance requirements.

Certification is generally not issued until identified deficiencies have been satisfactorily addressed.

Step 11: Issuance of Certificate

Where LASBCA is satisfied that all applicable requirements have been met, the Agency may issue the appropriate certificate or clearance relating to the building’s structural fitness or, where applicable, a Certificate of Completion and Fitness for Habitation/Use in accordance with the relevant regulations.
