Does a landlord have the right to enter with open notice for a full month?

I am in California, renting an apartment. Today i received a notice on my door from a Plumbing company, stating "we have been contracted to repipe your building. We will need access to your unit from 8:00am to 5:00pm on the following days monday 4/7/08 to friday 5/2/08. For questions contact your leasing office" I contacted the office and said i will give them permission to enter if i get 24hr notice prior to entry, but I do not give permission to enter freely for an entire month, and they said they can and will. Help... can they really do this?

my issue is allowing strangers to enter my apartment for a whole month, its like why dont i leave the front door wide open all day (for 30 days).i am lucky to be able to work from home 50% of the time and can arrange to be there when they need to enter but not for an entire month. Legally do I have any rights?

I am almost sure they CANNOT.
I don't know if you have this by you, but in wisconsin we have a tenant resource company, just look them up, call & ask. they are PRO renter, and basically do everything they can to back you and not the landlord. I think you're right with granting access if you get 24hr notice. A whole month with being able to have access is a little excessive and I would strongly suggest looking up in your yellow pages a company that can look more into it, whetehr its a tenant resource company or lawyer

not sure, but if your building has major plumbing issues, i would allow them to have that access myself as the issue can be complex and difficult to fix than it is if the plumbers don't have easy access...

Yes, they can do this, since they HAVE given you 24 hour (or more) notice. In fact, they have given you a full month's notice.

There need not be an individual notice given for EACH day, as long as you have been advised AT LEAST 24 hours in advance of the TIMES they will be there. As long as they gave you 24 hours notice of all the days they will be there, they are within their rights.

Your have the right to draw up a statement of condition. You
can permit the Landlord to have access to the space "if they
agree to take responsibility for the people that enter your
space". The agreement should state that the landlord takes
responsibility for missing or damage to the rented property.

The way you have presented the information it seem that the
workmen will have free run of the property for 8-9 hours, for
close to 30 days. Most times this is the need for the entire
building. The length of time in your space may be no more
than 2-3 hours. It is impossible for the workmen to say what
hour period they will be in your space. But it is not impossible
for the landlord to be responsible when they are there.
