Speaking during an interview on Inooro TV, Gachagua said the government promised to protect people's businesses.
"The government will see to it that a person earning Sh400 gets to earn double, but not vice versa," he said.
He said the decision by Sakaja to relocate long-distance public service vehicles from the central business district (CBD) to Green Park terminus will affect the industry and traders who depend on matatus to ferry their goods to the markets.
"Those pushing for matatus to be blocked from the city do not operate business in the CBD whereas those who have business are against the idea," the DP said.
He maintained that there is no need to relocate matatus to the Green Park terminus since there are no buses or commuter trains to ferry passengers to the CBD.
Gachagua also faulted Sakaja for ordering closure of clubs in residential areas without consultation with the stakeholders.
"The county government of Nairobi has issued licences to the bar owners and most of them had invested heavily, there was a need for the governor to give them a grace period," he said.
He also dismissed claims of favouring the Mt Kenya community, saying the government has to protect every hustler as promised during campaigns.
"We cannot be lending Kenyans Hustler Fund for them to start a business yet, on the other hand, we are ending what some have already started," he said.
Sakaja on Sunday said his government will work to transform the city despite criticism.
"Nairobi has become the talk of many because we are trying a new vision. Our city cannot remain as it has always been," he said.
