An 80-year-old disabled man was injured when a railing he had been assured was safe collapsed.
Maurice Scott was told by workers that the ramp outside his home was usable, but the handrail gave way.
Now the retired fireman is consulting his solicitor.
Mr Scott, from Guiseley, Leeds, had spoken to workers, who told him the ramp was ready to use.
“The rail came apart and I fell, so much that I injured myself,” he said. “I hurt the bottom of my back, my neck and my arm.”
Mr Scott has complained to housing management body West North West Homes Leeds (WNWHLs), on whose board he used to sit as a tenant’s representative.
He added: “It’s in the hands of my solicitor, for the sake of anybody else.”
A West North West homes Leeds spokeswoman said: “We would like to apologise to Mr Scott for this unfortunate accident, it is something that should not have happened.
“Where adaptations are being undertaken it is usual practice for the subcontractors work to be assessed and signed off by the WNWHLs adaptations team before a tenant is told it is ok to use.
“On this occasion this did not happen, and Mr Scott should not have been granted permission by the subcontractor for Morrison to use the ramp until work was completed to a satisfactory level.
She said they visited Mr Scott after the fall and ensured the rail was finished properly.
A spokesperson for Morrison, which carries out repairs on behalf of Leeds City Council, also apologised, adding: “A full health and safety investigation has since been carried out with our subcontractor S&C and we have now agreed a change of working practices with them, to ensure this type of incident does not happen again.”
