Proposed Bill set to mandate solar panels on new homes
If approved, the National Construction Authority (NCA), working with relevant government agencies, will identify zones within new developments where solar systems must be accommodated.
Kenya’s Senate is considering a Bill that would require all new buildings to allocate areas for solar energy systems, aiming to promote eco-friendly construction and strengthen resilience against climate change.
The National Construction Authority (Amendment) Bill, 2025, introduced by Migori Senator Eddy Oketch, sets out measures to integrate sustainable practices across the construction sector while safeguarding the environment.

“The construction sector plays a crucial role in the development of Kenya’s infrastructure and economy. However, it also significantly impacts the environment and is vulnerable to climate change risks,” the Bill notes.
If approved, the National Construction Authority (NCA), working with relevant government agencies, will identify zones within new developments where solar systems must be accommodated.
These zones will be selected based on adequate sunlight exposure to ensure efficient energy generation. The Cabinet Secretary will establish regulations to guide implementation.
Beyond mandating solar energy, the proposed law promotes various climate-smart building measures.
It encourages designs that can withstand harsh weather, incorporate green spaces and natural buffers, and adopt energy-efficient technologies.
The Bill further recommends using renewable energy sources, water-saving appliances, and systems for rainwater harvesting and greywater recycling.
It also emphasises using recycled, renewable, and locally sourced materials, minimising construction waste, and protecting natural habitats and ecosystems.
“These amendments ensure that standards, guidelines and regulations developed by the NCA for the construction industry include mechanisms that address climate change risks,” the Bill states.
“By doing so, the industry will be encouraged to reduce its environmental footprint and enhance resilience against climate change effects.”
Senator Oketch noted that the changes would allow the sector to adjust to evolving environmental conditions while supporting national efforts to curb climate change impacts.
The NCA oversees Kenya’s construction industry, registering projects and contractors, accrediting skilled workers and supervisors, enforcing standards and codes of conduct, and building capacity through research and training.
