Top of the agenda was affordable housing, sheltered accommodation and waste and recycling facilities, as the council showed Mr Khan a snapshot of priority projects coming to life across the borough.
First stop was the Housing Zone site at the Civic Centre on Lampton Road where work is under way to build more than 900 homes by 2022, half of them affordable.
This site receives direct funding from the Greater London Authority to achieve 50%affordable homes.
The Mayor was told 150 affordable homes are planned to be ready to move into by autumn 2018.
During the visit on Thursday (March 16) he was joined by leader of Hounslow council, councillor Steve Curran, MP for Feltham and Heston Seema Malhotra and chief executive of Hounslow council Mary Harpley.
Next up was a visit to the newly opened recycling facility - Recycle 360 - in Southall Lane, a subsidiary of the council-owned Lampton 360.
Here the Mayor met with staff whose job it is to collect the borough's recycling and waste and spoke to them about a rise in pay now that they are being paid the London Living Wage, following the transfer of services from Suez.
He also heard how in the future the site will be used by other organisations when Recycle 360 starts to tender other contracts, with profits to be used to protect frontline services.
Mr Khan said: “I was delighted to visit Hounslow and see for myself the excellent work the council is doing.
"From delivering genuinely affordable homes, to cutting waste and increasing recycling.
“As Mayor I’m determined to make London a fairer and more equal city, and it was great to meet people at Recycle 360 being paid the London Living Wage and hear how it has had a positive impact on their lives.”
The final stop on the tour was to a newly built sheltered housing scheme at Hogarth Court in Heston.
Staff and residents welcomed Mr Khan who was shown around the facility which houses 40 apartments suited for individuals as well as people with disabilties.
The building is part funded by the Greater London Authority (£2.2m) and Hounslow council (£5.8m).
Residents spoke about how living here has allowed them to live independently for longer.
Councillor Steve Curran, Leader of Hounslow Council, said he was delighted to welcome the Mayor to the borough.
Mr Curran added: “We wanted to show just how culturally diverse and thriving our borough is and how we are already on track with making those improvements and delivering our promises to provide a better future for all our residents.”
