Q: How many times can management enter your apartment in a month before it is considered harassment?

A: To answer this question, we need to consider California landlord-tenant law and the concept of reasonable entry. Here are some key points to consider:

1. Legal basis for entry: In California, landlords have the right to enter rental units for specific reasons, including making necessary repairs, showing the property to prospective tenants or buyers, and conducting inspections. However, this right must be balanced with the tenant's right to quiet enjoyment of the property.

2. Notice requirements: Generally, landlords must provide 24-hour written notice before entering a rental unit, except in emergencies.

3. Frequency of entry: California law doesn't specify a maximum number of times a landlord can enter a unit in a month. However, entries should be reasonable in frequency and duration.

4. Harassment: Excessive or unnecessary entries could potentially be considered harassment. The key factor is whether the entries are reasonable and necessary.

5. Government-funded housing: As you mentioned this is a low-income complex funded by government departments, there may be additional inspection requirements that don't apply to typical rental properties.

Given your situation:

1. The frequent notices (6 since March) and the extended period (from tomorrow through the 28th) seem unusually high.

2. The lack of communication about whether they actually entered and what was done (if anything) is concerning.

3. The repeated use of the same reasons for entry, especially after the stated task (smoke detector replacement) has been completed, raises questions.

4. The upcoming government inspection on the 28th may explain some of the increased activity, but not necessarily all of it.

To address this situation:

1. Document all notices and actual entries (dates, times, reasons given).

2. Ask management in writing for clarification on why so many entries are necessary and request that they inform you when they actually enter and what work was done.

3. If you feel the entries are excessive or unnecessary, you could file a complaint with the property management or the government agency overseeing the housing complex.

4. If the situation persists, consider consulting with a tenant rights organization or a lawyer specializing in landlord-tenant law.

While there's no specific number of entries that automatically constitutes harassment, the frequency and pattern you describe could potentially be considered unreasonable. The key is whether these entries are truly necessary and whether they're being conducted in a way that respects your rights as a tenant.
