Why Kiambu differs from Nairobi

Baseline rates on this site are surveyed for the Nairobi region. Everywhere else moves with three things: how far materials have to be hauled, whether there is a quarry or cement plant within economic distance, and what fundis charge locally. In Kiambu they work in your favour, about 1% below Nairobi — close to Nairobi supply chains.

The adjustment applies to materials and labour. County approval fees and the NCA levy are statutory and do not move with distance, which is why the gap between Kiambu and Nairobi is smaller in percentage terms on a small house than a large one.
