Executive Summary
On 19 September 2025, the Court of Appeal of Kenya issued a landmark judgment that has significantly reshaped the legal and regulatory environment for urban development in Nairobi. The case concerned the legality of high-rise developments along Rhapta Road in Westlands, with wide-ranging implications for zoning, planning instruments, and the statutory duties of Nairobi City County under Kenyan law.
The Court's ruling clarified the zoning status of Rhapta Road, upheld developers’ rights to proceed with high-rise projects (up to 20 floors), and issued a structural interdict compelling Nairobi City County to finalize and gazette lawful zoning plans. The case exposed critical failings in urban governance and has prompted judicially mandated reform within a strict six-month timeline.
The judgment provides much-needed certainty to investors and developers navigating the Nairobi real estate market.
The Case: A Much-Needed Clarification
The Court of Appeal directly confronted the "structural governance gap" that has undermined lawful urban planning in Nairobi. The judgment is notable not only for its substantive outcomes, but also for the judicial remedies applied—in particular, the use of a structural interdict, a rare but powerful constitutional tool.
Key Takeaways from the Judgment
1. Recognition of a Structural Governance Failure
- The Court acknowledged that Nairobi has no properly gazetted zoning frameworks under the Physical and Land Use Planning Act (PLUPA), 2019.
- The 2004 Zoning Guidelines were declared legally obsolete, having never been formalised under current statutory procedures.
- This has created a legal vacuum that enables discretionary, inconsistent decision-making, violating the rule of law and principles of sustainable urban development.
2. Application of a Structural Interdict
- Recognising that ordinary declaratory or injunctive relief would be insufficient, the Court issued a structural interdict — a supervisory constitutional remedy designed to address systemic violations.
- This interdict compels Nairobi City County to take specific legal and administrative actions, within a judicially supervised timeframe, to cure the ongoing illegality.
- This reflects evolving Kenyan jurisprudence aligned with Article 10, Article 174, and Article 43 of the Constitution, and draws from international best practices in urban governance and intergenerational equity.
3. Zoning Clarification – Rhapta Road is Zone 3C
- The Court partially allowed the developers’ cross-appeal, correcting the trial court’s misclassification of Rhapta Road.
- It affirmed that Rhapta Road is located within Zone 3C, as defined under the 2021 Nairobi Development Control Policy.
- Consequently, the maximum permitted height for developments along Rhapta Road has been increased from 16 floors (as previously assumed) to 20 floors, subject to infrastructure and environmental compliance.
4. Mandates Issued to Nairobi City County
Under the structural interdict, the Court issued a binding directive to Nairobi City County, including the following orders:
a. Gazette Lawful Zoning and Planning Instruments
- The County must complete, adopt (via County Assembly), and gazette a comprehensive Local Physical and Land Use Development Plan, in compliance with Sections 44–58 of PLUPA, 2019.
- Deadline: Six (6) months from the date of the judgment.
b. Conduct Meaningful Public Participation
- All planning processes must include genuine public participation, as mandated under Article 10 and Article 69(1)(d) of the Constitution, and Section 5 of PLUPA.
c. File Periodic Compliance Reports
- A progress report must be filed with the Court within three (3) months, and a final compliance report within six (6) months, allowing the judiciary to maintain oversight.
Legal Status of Existing and Pending Approvals
Pending formalisation of the zoning frameworks, the Court issued practical guidance to protect investment certainty and legal continuity:
- Valid Existing Approvals: All lawfully issued development approvals and NEMA licences already acted upon remain valid and enforceable. There will be no retroactive invalidation or demolition.
- Pending Applications: These will be assessed under PLUPA 2019 and its regulations, guided by the 2021 Development Control Policy, pending its formal approval and gazettement.
Implications for Developers, Investors, and Urban Planners
✅ Greater Legal Certainty
- The decision provides developers with clear zoning status and legal justification to proceed with 20-floor developments in Zone 3C, eliminating long-standing ambiguity.
✅ Protection of Existing Investments
- The Court has safeguarded the rights of investors who have acted in good faith under lawfully issued approvals, reinforcing protections under Article 40 (Right to Property) of the Constitution.
✅ Judicial Supervision of Urban Planning Reform
- For the first time, the Court has issued a time-bound, enforceable mandate on Nairobi City County to undertake systemic planning reform, supported by judicial supervision.
✅ Opportunity for Stakeholder Engagement
- Developers, landowners, and community groups now have a critical window to engage in the formulation of Nairobi's new zoning and land use policies.
✅ Policy Reform Aligned with Global Standards
- The judgment reflects international best practices in sustainable urban planning and urban rule of law, consistent with UN-Habitat, ICLEI, and OECD guidelines.
Conclusion
The Court of Appeal’s decision in Civil Appeal No. E160 of 2025 is a transformational moment in Kenya’s urban law. It confirms that Nairobi’s development must be guided by law, not discretion, and lays the groundwork for modern, enforceable, and inclusive zoning policies.
By confirming developers' rights, protecting lawful approvals, and ordering time-bound governance reforms, the Court has restored legal certainty, predictability, and public accountability in one of Africa’s fastest-growing cities.
