Put it either in OnPlayerConnect, or in OnPlayerSpawn (both'll work, I always put them in OnPlayerSpawn).

pawn Код:

public OnPlayerSpawn(playerid)
{
    RemoveBuildingForPlayer(playerid, 1266, 1538.5234, -1609.8047, 19.8438, 0.25);
    return 1;
}

Though it's unneeded in OnPlayerSpawn (it gets called all the time). You'd best put it in OnPlayerConnect
