from the perlre manpage: The numbered variables ($1, $2, $3, etc.) and the related punctuation set ("$+", "$&", "$`", and "$'") are all dynamically scoped until the end of the enclosing block or until the next successful match, whichever comes first.

So $1 is only set if the match succeeds, that's why it's a good idea to write 
if ($adress1 =~ /^([A-Za-z0-9öäåÖÄÅ][A-Za-zöäåÖÄÅ0-9\s\-\.\,]*)$/) {
    $adress1 = $1;
}
if ($adress2 =~ /^([A-Za-z0-9öäåÖÄÅ][A-Za-zöäåÖÄÅ0-9\s\-\.\,]*)$/) {
    $adress2 = $1;
}
