[CentOS] Permission question

Hello,

We own a CentOS Server which hosts a few domains using Cpanel, however each host or domain has its own user and its own folder under /home, we want a separate user(newuser1) to have read and write privileges in all home's subdirectories so we can do some tasks remotely using WinSCP, that user is already in the sudoers group and the root login is disabled in SSH for security, but I haven't been able to assign the correct privileges and rights to newuser1 using chmod -R owneruser:newuser1 /home/owneruserdir, everytime we login with newuser1 using WinSCP to /home and try to change directory to /home/owneruserdir we receive a permission denied message, so I don't know where else to look.

Any pointers will be apreciated.

Thanks.
