How to Apply for a Building Plan Approval in Kenya: County Government Process

Every construction project in Kenya—whether a residential house, commercial building, industrial facility or infrastructure development—requires building plan approval from the relevant county government before any work begins. This legal requirement is governed by the Physical and Land Use Planning Act 2019, the Building Code 2020 and NCA regulations. Building without approval attracts penalties including demolition orders, fines and criminal prosecution. This guide covers every step from engaging professionals and preparing drawings to county submission, NCA registration and final occupation certificates.

Why Building Plan Approval Is Required

County governments control development through building plan approvals to prevent unsafe structures, ensure projects align with county zoning plans, protect public health and safety, maintain environmental standards and manage infrastructure capacity (roads, sewerage, water supply). The approval process verifies that your proposed building complies with structural engineering standards, fire safety requirements, accessibility provisions, setback regulations, plot coverage ratios and height restrictions specific to your zone.

Step 1: Engage Qualified Professionals

Before preparing any drawings, engage the following licensed professionals. An architect registered with the Board of Registration of Architects and Quantity Surveyors (BORAQS) and the Architectural Association of Kenya (AAK) to design your building and prepare architectural drawings. A structural engineer registered with the Engineers Board of Kenya (EBK) to prepare structural drawings and calculations. A quantity surveyor to prepare bills of quantities and cost estimates. For larger projects, you may also need a mechanical engineer, electrical engineer and environmental consultant.

Verify that all professionals hold current practising licences—county governments reject submissions from unregistered practitioners. The architect's practising licence number must appear on all architectural drawings, and the structural engineer's registration must appear on structural drawings. Professional fees typically range from 6–10 percent of construction cost for architectural services and 2–4 percent for structural engineering.

Step 2: Prepare Required Documents

Compile the following documents before approaching the county government:

Land ownership proof: Original title deed or certificate of lease, or a certified copy from the Ministry of Lands. For leasehold property, ensure the lease has sufficient remaining years (most counties require at least 20 years). Official survey map from the Survey of Kenya showing the plot boundaries, dimensions and survey beacon numbers. Land rates clearance certificate from the county government confirming all land rates are paid up to date. Land rent clearance from the Ministry of Lands (for leasehold properties).

Architectural drawings (minimum four sets, typically six): site plan showing the plot boundaries, building footprint, setbacks, access roads and neighbouring structures; floor plans for each level; elevations (front, rear and side views); cross-sections; roof plan; and a schedule of finishes. Structural drawings: foundation layout, column and beam schedules, slab details, structural calculations and soil investigation report (for multi-storey buildings). All drawings must be on standard A1 sheets with proper title blocks showing project details and professional registration numbers.

Step 3: Submit to County Government

Submit your application to the county government's Department of Physical Planning and Development Control. Most counties now accept applications through online portals, though physical submission remains available. In Nairobi, applications are submitted to the Nairobi City County planning department. The submission package includes a completed application form (available at the county offices or online portal), all architectural and structural drawings, land ownership documents, rates clearance certificates, professional practising licences, and the prescribed application fees.

Application fees are typically based on a percentage of the estimated construction cost—usually around 0.5 percent for plan evaluation. This means a project estimated at KES 10 million would attract approximately KES 50,000 in plan approval fees. Additional fees include inspection charges of KES 5,000–10,000 depending on project size and category. Pay all fees through the county's official payment channels and retain receipts for reference.

Step 4: Plan Review and Site Inspection

After submission, the county planning department reviews your drawings against local development standards. The review checks compliance with zoning regulations (residential, commercial, industrial or mixed-use zones have different requirements), plot coverage ratios (typically 50–65 percent for residential, 80 percent for commercial in Nairobi), plot ratio (floor area to plot area), setback requirements (minimum distances from plot boundaries—typically 1.5–3 metres for residential), building height restrictions, parking provision requirements, and access road width.

County officers may conduct a site inspection to verify plot boundaries, check existing structures, assess access roads and confirm that the proposed development is feasible on the actual site. The review process typically takes 30–90 days depending on the county, project complexity and workload. Some counties offer fast-track processing for an additional fee. If the plans require amendments, the county issues a query letter specifying required changes—your architect addresses these and resubmits.

Step 5: NEMA Approval

Projects that may have significant environmental impact require an Environmental Impact Assessment (EIA) licence from the National Environment Management Authority (NEMA). The Environmental Management and Coordination Act requires EIA for projects including residential developments above a certain threshold, all commercial and industrial buildings, developments near water bodies, wetlands or forests, and projects in environmentally sensitive areas.

Engage a NEMA-registered EIA lead expert to prepare the EIA study report. The report assesses potential environmental impacts and proposes mitigation measures. Submit the report to NEMA with the prescribed fee (KES 10,000 for the EIA licence application). NEMA reviews the report, may conduct a public participation process and issues an EIA licence if satisfied. The EIA process can take 60–90 days, so initiate it early alongside your county approval application.

Step 6: NCA Project Registration

The National Construction Authority (NCA) requires all construction projects to be registered before work commences. NCA registration ensures that qualified contractors and supervisors handle the construction. Submit the following to NCA: county-approved architectural and structural drawings, contractor's NCA registration certificate and annual practising licence, project supervision plan, and construction programme.

NCA project registration is free for projects below KES 5 million. For projects above KES 5 million, NCA charges a building permit fee of 0.5 percent of the contract value. After online submission, the application takes a minimum of 7 working days to be evaluated. NCA issues a project registration certificate that must be displayed at the construction site throughout the building period.

Step 7: Commence Construction

With county approval, NEMA licence (if required) and NCA registration in hand, you can legally begin construction. Before breaking ground, ensure you have engaged an NCA-registered contractor with the appropriate category for your project size, appointed a qualified site supervisor (clerk of works), obtained a commencement notice from the county government, and notified neighbouring property owners as required by some counties.

During construction, the county building inspectors will conduct periodic inspections at key stages: foundation, ground floor slab, subsequent floor slabs, roofing and completion. Ensure your contractor schedules these inspections and that work does not proceed past each stage without the inspector's approval. NCA officers may also conduct unannounced site visits to verify compliance with approved plans.

Step 8: Occupation Certificate

After construction is complete, apply for an occupation certificate (also called a completion certificate or certificate of habitation) from the county government. This confirms that the building was constructed in accordance with the approved plans and is safe for occupation. The county conducts a final inspection checking structural integrity, fire safety installations, sanitation systems, electrical installations and general compliance with approved drawings.

Occupying or letting a building without an occupation certificate is illegal and can result in penalties, difficulties with property transactions and insurance claim rejections. The certificate is also required for connecting permanent utility services including electricity from Kenya Power and water from the county water company.

Common Mistakes and How to Avoid Them

Building without approval is the most serious mistake—county governments have authority to issue demolition orders for unapproved structures, as demonstrated by high-profile demolitions in Nairobi. Deviating from approved plans during construction (adding floors, changing use, extending beyond approved footprint) can result in stop-work orders and penalties. Using unregistered professionals or contractors leads to rejected applications and potential safety hazards. Always verify NCA, BORAQS and EBK registration of all professionals involved.

Conclusion

Building plan approval in Kenya involves multiple agencies—county government, NEMA and NCA—each with specific requirements and timelines. Budget 3–6 months for the entire approval process from initial submission to commencement. Engage qualified, registered professionals from the outset, prepare complete documentation, pay all required fees and follow the approved plans during construction. This disciplined approach protects your investment, ensures structural safety and avoids the costly consequences of non-compliance.
