Nairobi Governor Mike Sonko on Saturday ordered building owners within the Central Business District to repaint their buildings.

In what appears to be the latest raft of measures to clean up the city, Sonko said the move is aimed at restoring the city’s lost glory as the “green city under the sun”.

I humbly reminding all building owners within the city to repaint their buildings and repair the small section of pedestrian walkways in front of their buildings

The walkways should be repaired with even and coloured paving blocks.

Sonko said City Hall will only issue 2019 unified business permits to businesses in buildings and premises that will have been repainted.

He said the paint work and refurbishment of sidewalks should be done during the December festive season.

The governor spoke at Kiboro grounds in Mathare Constituency during the Nairobi monthly clean-up exercise.

I wish to encourage building owners to take advantage of this festive season when there will be lighter human traffic to bring back the aesthetic beauty of our city and improve the business environment

The governor said he understands the monetary strain the work will have on businesses but its a worthy cause to beautify the city.

County laws require that property owners repaint their premises every two years to maintain health standards.

Mombasa county embarked on a similar mission in July where building owners were instructed to repaint their buildings under the city regeneration programme.

Sonko also announced that his administration has launched an aggressive campaign to enforce revenue compliance.

The governor warned that action will be taken against building owners who fail to clear their rates.

For Nairobi to deliver services, we must collect revenue. I appeal to all building owners to clear their rates arrears to avoid being clamped.

Sonko cautioned corrupt county officials who collude with traders to deny the county government revenue that they will face stern action.

I'm aware that we are losing a lot of revenue in our markets and advertising sector through some corrupt county officials, your days are number

The clean-up exercise was graced by UN Habitat executive director Maimunah Mohd Sharif and Fernando Coimbra, the chairman of the committee of permanent representative to the UN-Habitat.
