The potholes are located on an access road leading to Charlemont Community & Youth Centre, in West Bromwich.
David Fisher, who is standing as a councillor in May, has called on Sandwell Council to enforce the landowner to take action.
He said: “It is the only access road to the community centre and football pitches, and is located between two high rise flats.
“The council used to own the land but sold it to the leaseholders in 1988. I noticed these potholes occurring in the middle of last year.
“I contacted the council and they said they don’t own the land but they would try and get in touch with the leaseholder to look into it.
“I chased it up again with the council but they couldn’t get hold of the leaseholders to see what could be done, to get them to fix it.
“I have never seen a road like it. But because it is an access road, it acts for either vehicles or people on foot.
“If you have got some people with mobility issues going there, if you are a wheelchair user or on an electric scooter, with how deep they are, one could topple over.”
Mr Fisher is the Conservatives candidate for Charlemont with Grove Vale.
In response, cabinet member for inclusive economic growth Councillor Danny Millard said: "The council has been aware of the issue for a while and has been actively seeking out the respective owners of the property at various times in a bid to try and agree a way forward, so the condition of the access road can be improved.
"As a council we will continue to pressure the private road owners to maintain the standards set by this council.
"Our efforts to contact the current owner will continue in the hope to that we can work with them to resolve this issue."
