The Architectural Association of Kenya (AAK), led by its Coast Branch Chairperson Arch. Duncan Odhiambo, has opposed the proposed taxes on construction materials under the Finance Bill 2026, warning that the new levies will increase the cost of construction projects across the country and make housing more expensive for millions of Kenyans.

AAK says ceramic tiles will attract a 35% import duty alongside an excise duty of 5% of the customs value or KSh 200 per square metre (whichever is higher), a move that could push retail prices from about KSh700–900 to as high as KSh2,500–3,000 per square metre. The association adds that sanitary ware, glass, aluminium profiles and selected wood products will also face steep import and excise taxes.

According to the architects, the increased taxes will drive up the cost of constructing homes, schools, hospitals and commercial buildings, with developers expected to pass the additional costs to buyers and tenants.

The association further warns that higher import barriers could reduce competition, leaving a few local manufacturers with greater influence over market prices.

AAK has called on the government to suspend the proposed taxes and engage industry stakeholders before implementation. It argues that unless the measures are reviewed, they could slow investment, threaten jobs in the construction sector and undermine Kenya’s affordable housing agenda.
