Amanda:
That's good that you take him out often. I think that you either need to watch more closely or to use a crate for his naptime so you don't have to watch all the time. If he's peeing in the hallway after he awakens and drinks and you miss it, he basically thinks the hallway is a safe place to potty. Make sure you clean the hallway well with an enzymatic cleaner so that the smell of urine is gone.
So the trick is to get him to take his naptime in a small place - such as a crate (if he falls asleep outside of the crate you can gently pick him up and move him into the crate - if he wakes up, ignore him and he will tend to fall asleep again in the crate). Dogs tend to not want to eliminate in the place that they sleep. You are correct in that 9 weeks is young to be able to "hold-it" for long. The recommendation during the day is that a puppy can only be crated for his age in months plus one (thus, your puppy can only hold it for 3 hours at the most during the day). At night, if they are asleep, they can often hold it for longer. It definitely helps to have a puppy sleep in a crate at night (thus, if he wakes up and has to go, he will tend to cry, whine or get restless, thus, letting you know he needs to go out).
To teach him to indicate that he needs to go out, the crate can help if he learns to whine when he has to go. Be careful to not let him out of the crate if he is barking or whining to be let out when you know he does not have to go. You know he has to go when he's been asleep in the crate and then wakes up and whines. Furthermore, you can teach him to ring a bell to ask to go out. Hang a large craft bell or sleigh bell on the door you take him out of and each time you take him out to eliminate, ask, "do you want to go out!" as you place his nose near the bell and you gently tap it with your hand. If he ever, even accidentally, rings it on his own, ask if he wants to go out and take him out.
That's great that he is going outside when you take him - make sure to praise him and sometimes even have a small treat outside with you to give to him. A very important part of housetraining is teaching a young dog that outside with you watching is a great place to go. You want to build up the outside rewards prior to correcting going in the wrong places (it's best to supervise inside more than punish - and the punishment should never be harsh and never be sticking his nose in it).
Following is some additional advice concerning housetraining a dog:
Take him out on leash to the area that you wish him to potty in. Puppies tend to have to eliminate anytime when they change activities so you need to be able to guess when he has to go, take him out on leash then and reward him with praise and a treat for going outside (bring the treat out with you instead of bringing him back in for the treat).
A crate is a management tool to help teach your puppy how to "hold it". If you are not using a crate you will need a room with no carpet where he can safely be gated when you cannot watch him. Feel free to place some puppy pads or papers on the floor if you have to be gone for too long for him to hold it (i.e. over 3 hours for a 9 week old pup)
To work on housetraining him, during the day you need to develop a set schedule (it can vary some if your schedule has to change - but it does have to be a daily schedule). There are times that you know he will have to go, for example, first thing in the morning, after waking up from a nap, a certain period of time after eating or drinking, after playing. Keep a small notebook as a journal to get an idea of his schedule and when he has been successful in going outside and when he has had accidents.
The first most important part of housetraining is to take him out on leash so he cannot become distracted from the task at hand and so you can condition the area where you want him to eliminate in. Bring small yummy treats in your pocket. When he does squat, put a word to it such as "hurry" or "get busy" - at first say the word AS he is eliminating, then start to say it a bit sooner in time - i.e. as he is sniffing. When he is successful outside, praise and then give him a small treat. As I mentioned before, it is important to treat him outside and to not bring him back inside for the treat. So your job outside is to build a "bank account" of successes. We want him to really be praised and rewarded for going IN FRONT OF YOU outside.
A mistake people make is to catch the dog on mistakes too often inside without rewarding enough successes outside first and having the dog figure out that the solution to the riddle is "human present versus human absent" instead of "outside versus inside". Unfortunately, it is very true that it is always "safe" to go when a human is not around.
When your dog is inside and loose in the house, you need to be constantly watching him. Meaning do not take your eyes off of him for a second. It helps to keep him in the same room as you with a gate or closed door or to tether him to you via a leash and walk around with him tethered to you. If you cannot supervise, that's where the crate (or gated area) comes in. During the day a 9 week old puppy can hold it in the crate for his months of age plus one (meaning your puppy can be in the crate during the day for no longer than 3 hours at a time). At night pups can hold it for longer if they remain asleep.
When you catch him in the act of eliminating inside, say "ah ah" and take him outside.
You do not want to come down too hard and scare him, but you do want to educate and startle him enough that he stops in mid-stream or mid-poop! The best learning experience is when you catch him inside and the "ah ah" stops him and then you take him out and he continues the job outside for praise and a treat. If when you say "ah ah" you are having trouble catching him, then leave a line attached to his collar so you can grab it and go. Never leave the line on him when you are not supervising (actually until he is housetrained you must always be supervising anyhow). If somehow he has an accident that you did not see happen, just clean it with a good odor eliminating enzymatic cleaner (I do not let the pup watch me clean it up), but yell at yourself for not supervising, not at the puppy since you missed it.
How is he doing at night? Where does he sleep at night? Is he holding it all night? If so, that is great. If not, it does help to teach a puppy to sleep in a crate at night (the crate can be in your room near your bed).
It is very very typical for a puppy to be outside - even for hours at a time - and then come in and pee. The pup just does not yet understand. And if a pup is out for a long time, then outside becomes a place to do more than his business. It becomes a place to hang out, to rest and to play. It's best to have a puppy out less and teach the puppy that outside is for doing business (play with the puppy inside during supervised inside time). I don't mean to not take a puppy out at all for fun - definitely get the puppy socialized and okay with being outside - start to take short leash walks in the neighborhood. But do not confuse the potty area with the resting and play area. Oftentimes a puppy will be outside resting, playing and getting distracted and be too busy to stop and pee. When they get brought back inside they settle a bit and realize that "oops" I have to pee now - and the carpet looks like a fine place to go.
Remember that housetraining is about education, not about punishment. Your goal is to build up a "bank account" of successes going in front of you outside, catching him in the act of making a mistake inside and saying "ah ah" and redirecting him outside. That is how he will learn that housetraining means inside versus outside (and that it has nothing to do with whether you are present or absent).

Hope this is helpful. Good luck with your new puppy!
As you noticed, nighttime is not usually the problem, if asleep a young puppy can tend to hold it through the night (once they have reached that ability to do so - however, it's easier for a large breed than a small breed - which is good for you since he is a large breed!)
So that's good that he is being crate trained at night and is holding it.
You are correct, it's too long to leave him in the crate while you are at work. At his age, he can only be in the crate 3 hour maximum blocks of time during the day. Plus, even if your dog walker comes every couple of hours, it's a good idea to not crate him for the entire 8 hours since that is a long time to be crated.
When you are home, I would suggest using the crate for naptime when you cannot watch him. Or even if it is not naptime, but you need to do something and you will not be able to watch him - use the crate. Housetraining takes a lot of watching! Also, use the crate for short periods at times when you think he has to go and he just has not gone yet. For example, when you take him out and he pees, but you know he still has to poo and you don't have time to stand out there any longer (or the weather is not conducive to waiting any longer) - then bring him back in, put him in the crate for 10 or 15 minutes and then try taking him out again. Once he goes, he has earned some free time in the house. So, the times you are home and supervising the trick is to supervise and keep track whether he is "full" or "empty" - having a consistent feeding and watering schedule helps with this.
When using a crate to teach housetraining, it is important to provide one-on-one time with him, teach him to play games such as hide-n-seek with his toys and also teach him to find you when you hide, and also, make sure he is getting enough exercise. Furthermore, a dog of his adult size will need obedience training to be an enjoyable companion, so a Kindergarten Puppy Class is highly recommended along with the next level of classes after that (positive motivational training instead of corrective training is important). Teaching a puppy (mind-work) helps to wear them out and a tired puppy is a good puppy (there are "puzzle toys" such as the Buster Cube in which a puppy has to move the toy around to get the treats out) - these puzzle toys are good to put down when you leave (I pick them up most of the time and only use them when I leave or when I need a special toy to keep the puppy busy).
Now for when you are at work between 3 and 11 pm, my suggestion is to gate him in a room without carpet. Since that's 8 hours, there's no way he can hold it for that long. That's great that someone is walking him 3 times when you are at work; so in that case, maybe he could physically be able to hold it, but he does not know to do that yet. The reason I said to leave him in a room without carpet is that dogs become conditioned to go on certain surfaces that they get used to - and carpet is a comfortable place for a dog to choose to go - and you definitely do not want a dog used to going on your carpet.
So, if I have to leave a dog for longer than he's able to hold it, I choose a hard floor surface since it's easier to break them of going there (and easier to clean up). If the spare bedroom is carpeted, it may work to buy some rollout flooring at Home Depot or Lowes and roll it out in the room to cover all the carpet. You may also place some puppie piddle pads or newspapers on the floor for him to hit (I tend to not papertrain - meaning I don't reward a puppy for hitting the papers, but I do use papers when I'm gone for a long time just to make sure the puppy has a place to use) - the papers are sort of "no-man's zone" - meaning a puppy would not get corrected for hitting the papers nor praised. I only reward a puppy for going outside.
While you are at work, I'd leave the puppy in the crate for one block of time each day and out the rest of the time. I'd get the person who is coming 3 times to walk him to keep notes in a small notebook - they just need to write down what time they came and whether the puppy kept the room clean or had an accident (are the accidents only pee or sometimes also poo?) - They need to note whether the accident was pee or poo.
So say, the dog walker comes at 5pm, 7pm and 9pm - that means the puppy is in from 3 to 5 (2 hrs), from 5 to 7 (2 hrs), from 7 to 9 (2 hrs) and from 9 to 11 (2 hrs). That is good. A 9 week old pup should be able physically to hold it for 2 hours (but may not know that that is a thing to do unless in a small den-like area).
So, if your dog walker comes at 5pm and everyday it is clean; but then comes at 7pm and the puppy tends to have had an accident; then I'd leave the puppy loose in the room at 3pm and have the dog walker walk the dog at 5pm and then place the puppy in the crate until 7pm, walk the puppy at 7pm and leave the puppy loose until 9pm.
If your dog walker comes at 5pm and that's when he/she tends to find an accident, then I'd leave the puppy in the crate when you leave and then have the dog walker come at 5pm and walk the puppy and then leave him loose after that.
If the accidents are variable, just leave the puppy in the crate at a chosen time for a week and then the next week change the daytime crating time to another time.
By using the crate for a limited time during the day, your puppy will begin to learn that holding it is possible for short times during the day.
To make it easier on the pup, you could even plan to leave him in the crate at first when you leave and have the dog walker come after 1/2 hour and then gradually extend the time that he/she pays the first visit (i.e. come after 45 mins, then come after 1 hr, then come after 1 1/2 hrs, etc).
Amanda asked - Do you think this will get better as he gets older and can hold it longer, or will he simply think it's ok to pee there?
I think that he might think it's okay to pee in areas of similar surface when left alone (or just in that room?) - however, I am also sure that age will help him to hold it longer. My main advice it to not leave him in a carpeted area while you are at work (and remove all throw rugs).
Hope this helps.
