10 Construction Laws Every Lagos Property Owner Must Know

The recent demolition of about 17 houses near Oral Estate, before the Ikota River in Lekki, for allegedly encroaching on the river’s Right of Way (RoW), and similar enforcement at the Trade Fair Complex in Ojo, have once again drawn attention to the importance of understanding Lagos State’s construction laws.

The Lagos State Government insists that these exercises are not arbitrary but part of its effort to enforce planning and environmental laws across the state. Officials say many of the affected buildings were erected without valid permits, on restricted zones, or within government-acquired areas.

For anyone planning to buy land, build, or invest in Lagos real estate, here are 10 key construction laws you must understand  and comply with  to avoid demolition or loss.

A Building Permit Is Mandatory Before Construction

Before starting any project, developers must obtain a Planning or Development Permit from the Lagos State Physical Planning Permit Authority (LASPPPA).

Without this, your structure is illegal, no matter how much you’ve invested.

Several of the recently demolished properties reportedly lacked valid permits.

Every Project Must Display a Site Board

Lagos law mandates that all construction sites display a project site board showing:

• Permit number

• Project title

• Names of the professionals involved

• Approved number of floors

Failure to display this board signals non-compliance and can attract inspection or closure.

Permits Expire After Two Years

If construction does not begin within two years of obtaining your Planning Permit, it becomes invalid.

Many developers are unaware of this clause and risk sanctions if they resume building after expiry without revalidation.

All Buildings Must Meet Structural and Safety Standards

The Lagos State Building Control Agency (LASBCA) enforces compliance with the National Building Code.

Using substandard materials, poor supervision, or violating structural designs can result in site shutdown or demolition.

Certificate of Completion Required Before Occupation

No one can legally occupy or rent a completed building in Lagos without a Certificate of Completion and Fitness for Habitation issued by LASBCA.

Skipping this step is a serious violation that can lead to sealing or demolition.

Alterations or Renovations Also Need Approval

Modifying or extending an existing structure without a permit violates Lagos construction law.

Even minor changes like converting a residential building into commercial use require fresh approval from the appropriate agency.

Observe Mandatory Setbacks and Airspaces

Developers must maintain required setbacks for drainage, ventilation, fire access, and future road expansion.

Encroaching on these spaces remains one of the top reasons properties get flagged for demolition.

Unsafe or Non-Conforming Buildings Can Be Demolished

Under Lagos law, any distressed, illegally constructed, or non-conforming building can be demolished after due notice.

The recent demolition exercises by FHA and LASBCA were largely justified under this clause, according to government statements.

Insurance Policy Required for Buildings Above Two Floors

Developers handling multi-storey projects must obtain Construction All-Risk Insurance and Public Liability Insurance.

These policies protect workers, occupants, and nearby residents in case of accidents or building collapse.

Inspections Are Routine and Mandatory

LASBCA conducts regular inspections during construction to ensure compliance with approved plans.

Ignoring stop-work orders, alteration notices, or inspection queries is a serious offence under Lagos law.

Before buying, building, or developing in Lagos, verify every document, secure approvals, and comply with safety standards. It’s the only way to protect your investment and avoid heartbreak.
