Regret to hear of your situation, but any well written lease will clearly indicate
that a landlord has a right to enter the property after giving you sufficient notice.
Clearly, the tenant is in default of rent and hence the landlord has given a 3 day notice to
pay or quit.
Yes he can ask a sub tenant to stay and ask the tenant to leave. It comes down to paying the mortgage. Time for the tenant to move on.
The simplest way to view it is that the landlord has given you the right to exclusively live in a inhabitable environment in exchange for money. He needs access to the property to be sure it is in good condition and to maintain it. He is required to maintain it. If the landlord goes outside of that, it can cost him. It can cost the tenent if he interferes with the rights and duties of the landlord.

Here is the link to the California Landlord Tenant Handbook. It should clarify the rights of each party.
The first thing I tell people is to read their lease. The lease is what you and the owner have agreed to. Keep in mind, although you each have legal rights, he is the owner and if he has given a 3 day pay or quit the tenant has probably breached their lease. This person owns the property and probably has mortgage to pay as well. How would you deal with the situation if it were reverse? This landlord also will be the reference to the tenant when the tenant is looking for their next lease. If both parties can work this out it could be a win win.
All the best to you.
Are you asking if the landlord can have work done on a rental after he has given notice to a tenant to pay rent or quit?
As long as a tenant occupies a rental, they have the right to "quiet enjoyment" of the rental. In other words, the landlord can't send in a crew to intall upgrades that would inconvenience a tenant or deny use of all or part of the property. The landlord CAN make repairs, but generally not upgrades unless you agree to them. Until your lease expires or you are legally evicted, all your rights as a tenant remain in place. Even if you fall behind on your rent.
The question of sublets is a bit more complicated. Some landlords structure their leases so that the sublet agreement is more between the landlord and subtenant than it is between tenant and subtenant. They do this to have more control over the subtenant in the event that the tenant becomes a flake. Other landlords go the other way, making the subtenant the complete responsibility of the tenant and making the subtenant agreement void if the primary lease is terminated.
If you're having trouble with either of these issues, I recommend you speak with an attorney who specializes in landlord/tenant law and can advise you properly on your specific situation.
