TL;DR: Building legally in Lagos is a two-agency process: the Lagos State Physical Planning Permit Authority (LASPPPA) grants your planning permit (the approval to build), and the Lagos State Building Control Agency (LASBCA) monitors construction through stage certifications until it issues your Certificate of Completion and Fitness for Habitation. You'll need title documents, a survey plan, and stamped architectural, structural, mechanical and electrical drawings from registered professionals. Start before you buy materials — building without a permit risks sealing, demolition, and a regularisation process that costs more than doing it right.
Confusion here costs people months, so let's settle it:
You need both, in that order. The process now runs substantially through the state's electronic planning permit platform, and official timelines for complete applications run in weeks — but incomplete submissions are what actually stretch timelines, so treat document preparation as the main event.
Before any drawing matters, your land paper must be in order:
If your title needs perfecting (an assignment without consent, an excision issue), expect the approval process to force that conversation first.
Approvals require drawings prepared, signed, and sealed by registered practitioners:
Your professionals also shepherd the application. Choose them for their approval track record in your district, not only their design flair.
Submit through the LASPPPA district office covering your site (or the electronic platform), with drawings and documents. You'll receive an assessment of statutory fees — processing, and related charges based on the development's size, use, and location. Pay into designated government channels only, against official assessment notices. Any fee that can't be receipted by the state isn't a fee.
Site inspection by officials follows — they verify the survey, land use, and planning conditions on the ground.
Your drawings are vetted against planning standards and the building code. Larger or taller buildings route through concurrent approvals — drainage clearance (Ministry of Environment), traffic, lands, and escalating approval levels as height increases. Under the state's published routing, approval authority climbs from district officers for low-rise to the Commissioner and above for high-rise — which is why a bungalow and a six-storey block do not experience the same process.
Corrections at this stage are normal. Your architect resubmits; this loop is where responsive professionals earn their fee.
With the permit issued and endorsed drawings in hand, you move to the construction phase:
At completion, a final joint inspection (your consultants plus the agency) checks the building against approvals. With electrical, mechanical, fire and other certifications in place, LASBCA issues the Certificate of Completion and Fitness for Habitation. Legally, occupation comes after this certificate — and practically, the certificate matters for insurance, for corporate tenants, for valuation, and for resale. A building without it carries a permanent discount and a question mark.
Contravention notices, site sealing, and ultimately demolition exposure. Regularisation exists for some existing buildings — assessment, penalties, and retrospective processing where the building can be regularised — but it costs more than compliance and isn't guaranteed. Every year, marked buildings in Lagos remind the market that this is not theoretical.
LASPPPA issues the planning permit (approval of what you may build). LASBCA monitors construction — stage inspections and certification — and issues the Certificate of Completion and Fitness for Habitation.
Title document (C of O or consented assignment), registered survey plan, and signed/sealed architectural, structural, and (for larger builds) mechanical/electrical drawings from registered professionals — plus a soil test report where required.
Complete applications through the electronic system are processed in weeks per official timelines; height and complexity add concurrent approvals. In practice, incomplete documentation — not the agency — causes most delays.
No — commencing without a permit risks sealing and contravention action. Stages built without LASBCA certification also create problems at completion certification.
Yes. It evidences lawful completion; banks, insurers, corporate tenants, and future buyers ask for it. Buildings without one trade at a discount and carry legal exposure.
