Residents in Pocklington, including some who are disabled, have been forced onto the road after workers at the Rogerson Court development blocked the footpath with their vehicles.
Delivery lorries have also blocked access to the footpaths at the new McCarthy and Stone site.
Residents alerted Pocklington Ward Councillor Andy Strangeway to the situation who was in the area for a meeting.
He said: “At the top of Scaife Garth there’s an access that goes through to the doctors and this is disabled access.
“People in the area say that the workers are blocking the footpath with their vehicles and that some of the delivery lorries are blocking access.
“If delivery lorries can’t get to the site with ease than perhaps drivers should be using smaller vehicles.
“I thought it was rather ironic that the people who are building a retirement development, looking after people with disabilities, are stopping people with disabilities using the footpath and denying them access.”
John Allsop, construction manager for McCarthy and Stone said: “We are aware of complaints regarding irresponsible parking on Scaife Garth and we sincerely apologise for any inconvenience caused to local residents. We would like to reassure people that we take these matters very seriously, and our site manager is committed to minimising any further disruption.
“We were upset to hear that local people had experienced difficulty using the footpath, and we acted immediately to resolve the matter. Going forward a nominated parking attendant will be on hand to supervise parking and direct vehicles to an alternate car park nearby.
“Where possible, our contractors are also being encouraged to share a mini bus to the site or to van share, in order to reduce vehicle numbers.
“We would like to thank members of the public for their continued patience and understanding, and apologise to anyone that might have been affected.
“We are doing everything we can to ensure this doesn’t happen in future.”
