Ridgeways zoning
Ridgeways is a planning zone in the Roysambu area of Nairobi. Under the Development Control Policy 2026 it is for low-density residential area use. A building here can have up to 1 floor and cover up to 50% of its plot. All its floors together can add up to 100% of the plot's area. The smallest plot allowed is 0.2 ha (2,000 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. For example:
| Plot size | Area | Most floors | Largest footprint | Most floor space | |
|---|---|---|---|---|---|
| 0.05 ha | 500 m² | 1 | 250 m² | 250 m² | Below this zone’s smallest plot |
| 0.1 ha | 1,000 m² | 1 | 500 m² | 500 m² | Below this zone’s smallest plot |
| 0.2 ha | 2,000 m² | 1 | 1,000 m² | 1,000 m² | |
| 0.201 ha | 2,005 m² | 1 | 1,003 m² | 1,003 m² | A typical plot here |
| 0.25 ha | 2,500 m² | 1 | 1,250 m² | 1,250 m² |
Read the way the Nairobi Maps map reads the policy. Plots facing Kiambu 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 Ridgeways
Commercial (2 Levels) on the first row on either side of Kiambu Road between Tala Road and Northern Bypass. Low density residential, No densification.
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 Ridgeways
How many floors can I build in Ridgeways?
Up to 1 floor under the Nairobi Development Control Policy 2026. The zone's own rules can change the number for particular plots, so check your exact plot on the Nairobi Maps map.
What is the minimum plot size in Ridgeways?
0.2 hectares, which is 2,000 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 Ridgeways?
100%. All floors together can add up to 100% of the plot's area — for example 1,000 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 Ridgeways zone cover?
Roysambu ward, by the boundaries on the Nairobi Maps map.
How do I get approval to build in Ridgeways?
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.
