A headline about a 20-floor cap can sound like permission to build 20 floors. That is not what the Court of Appeal decided. The judgment in Claire Kubochi Anami & 2 others v County Executive Committee Member, Built Environment and Urban Planning, Nairobi City County & 20 others, Civil Appeal E160 of 2025, was delivered on 19 September 2025. It concerned one appeal and one cross-appeal from the Environment and Land Court's 23 January 2025 judgment in Nairobi EP E030 of 2024, not a new approval process for every development on Rhapta Road. Court of Appeal judgment (pp. 1-2; pp. 12-15, paras. 25-35; p. 50, para. 108)
The lower judgment was not the final planning answer
The residents' association officials had challenged planning decisions around development in the Rhapta Road area. The ELC had made several orders, including a 16-floor interim limit. On appeal, the Court of Appeal treated those as lower-court orders under review, not as settled final development controls. Court of Appeal judgment (pp. 12-15, paras. 25-35)
That distinction matters in due diligence. A title search may confirm registered ownership. It does not answer which planning instrument applies, what height or density controls are legally usable, whether a specific project has approval, and whether infrastructure, environmental and parcel-level conditions still constrain the site.
The Court also preserved the ELC's ability to hear the systemic constitutional planning-governance petition. But that did not abolish ordinary specialist routes for individual environmental licences, approval conditions or compliance disputes. Court of Appeal judgment (pp. 27-28, paras. 59-63)
Planning instruments were treated differently
The Court separated the legal status of several planning references. It said the 2004 guidelines no longer had binding status under the devolved framework. NIUPLAN 2016 was an approved strategic plan, but not a parcel-specific height permission. The 2021 development-control policy lacked full force without County Assembly approval and gazettement, although it could still guide administration persuasively within statutory safeguards. Court of Appeal judgment (pp. 29-32, paras. 67-72)
That is the core lesson. A planning document can be relevant without being final building permission. A strategic city plan can shape policy without proving that a particular plot may carry a particular tower.
The 20-floor point was qualified and interim
The cross-appeal partly succeeded because the Court corrected the zoning classification. It rejected reliance on Google Maps to authenticate disputed zoning boundaries without expert survey evidence and treated Rhapta Road, on the record before it, as Zone 3C rather than Zone 4 or 4B. Court of Appeal judgment (pp. 34-35, paras. 78-81; p. 47, para. 107(b))
The practical result was an adjusted interim cap of 20 floors for projects with principal access and frontage on Rhapta Road pending final County action. Even that was not unconditional. The Court preserved plot ratio, coverage, infrastructure capacity, servitudes, upgrades, environmental controls and stricter parcel-specific constraints. It was not a Nairobi-wide rule, not proof of current permission, and not a judicial authentication of every map boundary or approval file. Court of Appeal judgment (pp. 34-35, paras. 80-81)
Environmental and existing-approval issues also had limits
The residents' environmental challenge failed on the record. The Court noted the agreed affidavit procedure and found no established ultra vires, unfair or irrational NEMA process, and no identified licence shown to lack statutory steps. That is not the same as a finding of zero environmental harm or permanent compliance by every project. Court of Appeal judgment (pp. 38-39, paras. 87-90)
The remedy was structural. Save for the Court's own planning-governance orders, the residents' appeal was dismissed. The cross-appeal was partly allowed to correct the zoning classification. Within six months of the judgment, the County was ordered to complete, adopt through its Assembly and gazette pertinent plans and/or a development-control policy or code, with participation and technical parameters. An interim report was due within three months and a final report within seven days after the six-month period. This article does not assess later compliance, breach, extension or present planning status. Court of Appeal judgment (pp. 46-49, para. 107(a)-(c))
Existing approvals and environmental licences lawfully issued and acted upon were not invalidated absent demonstrated illegality. That protected reliance; it did not certify every approval as lawful. Pending applications remained subject to the Physical and Land Use Planning Act (PLUPA), regulations and consistent transparent guidance. Each party bore its own costs. Court of Appeal judgment (pp. 49-50, paras. 107(d)-(e))
For buyers, lenders, developers and advisers, the due-diligence question is therefore not "does the title exist?" or "what is the headline floor count?" It is: what dated evidence supports the parcel's zoning, what controls still apply, what approvals actually exist, and what later public action has been documented?
ArdhiScore helps organise available dated parcel evidence and the questions professionals need to resolve. It does not authenticate zoning maps, guarantee a buildable height, approve a development, confirm current compliance or replace advocates, planners, surveyors, valuers or environmental professionals.
