Along Thika Road zoning
Along Thika Road is a planning zone in the Roysambu area of Nairobi. Under the Development Control Policy 2026 it is for high-density residential use. A building here can have up to 20 floors on the largest plots (fewer on smaller ones) and cover up to 50% of its plot. All its floors together can add up to 1,000% of the plot's area. The smallest plot allowed is 0.1 ha (1,000 m²).
Figures from the Nairobi City County Development Control Policy 2026, as mapped by Nairobi Maps. Updated 2026-10-24.
What the figures mean for a plot
The footprint is the plot's area times the ground coverage. The floor space is the plot's area times the plot ratio — unless the floors run out first, and here the policy allows fewer floors on smaller plots. For example:
| Plot size | Area | Most floors | Largest footprint | Most floor space | |
|---|---|---|---|---|---|
| 0.05 ha | 500 m² | 12 | 250 m² | 3,000 m² | Below this zone’s smallest plot |
| 0.1 ha | 1,000 m² | 12 | 500 m² | 6,000 m² | |
| 0.197 ha | 1,973 m² | 12 | 987 m² | 11,838 m² | A typical plot here |
| 0.25 ha | 2,500 m² | 20 | 1,250 m² | 25,000 m² |
Read the way the Nairobi Maps map reads the policy. Plots facing Thika Road have their own terms in this zone’s rules, which these rows do not apply. Across Nairobi, a plot smaller than 0.05 ha (500 m²) can hold only one home. For your exact plot, open it on the map: Nairobi Maps works the figures out for that plot.
What the policy says about Along Thika Road
Densification on first and second rows along Thika road to 20 floors on 0.2ha and 12 floors on 0.1ha. Infrastructure: To secure approvals for commensurate expansion of sewer, water, electricity, roads by utility providers prior to commencement of densification. Privately developed infrastructure is also encouraged upon approval.
Quoted from the policy. These rules can change the figures above for particular plots — for example by plot size or for plots facing a named road.

Questions about Along Thika Road
How many floors can I build in Along Thika Road?
Up to 20 floors on the largest plots under the Nairobi Development Control Policy 2026, and fewer on smaller ones: 12 on a 0.05 ha plot and 20 on a 0.2 ha plot. Check your exact plot on the Nairobi Maps map.
What is the minimum plot size in Along Thika Road?
0.1 hectares, which is 1,000 square metres. Land in this zone cannot be split into plots smaller than that. Across Nairobi, a plot under 0.05 ha can hold only one home.
What is the plot ratio in Along Thika Road?
1,000%. All floors together can add up to 1,000% of the plot's area — for example 10,000 m² of floor space on a 1,000 m² plot. The ground coverage is 50%, so the building can stand on up to 500 m² of that plot.
Which wards does the Along Thika Road zone cover?
Roysambu ward, by the boundaries on the Nairobi Maps map.
How do I get approval to build in Along Thika Road?
Building plans are submitted to Nairobi City County through its online planning system, NPDMS, by a registered architect and engineer, and they must keep within this zone’s limits set out above. If the use you want is not one the zone allows, a change of use comes first. Check your plot on the Nairobi Maps map before the drawings are made.
