Tenants can’t unreasonably refuse access, but they can set reasonable conditions. For example, they may:
limit access to certain times of day and days of the week;
refuse open homes and auctions on site;
ask to be present during open homes;
Tenants may not agree to open homes or auctions on site. Instead, they can insist that the property be shown by appointment only. They could also ask for a temporary rent reduction for the inconvenience of allowing open homes. The landlord does not have to grant such a request.
简单点说就是，你不能无理地拒绝房东让人来看房，但是你可以设定条件。
你可以拒绝open home或者auctions on site。你可以要求必须要appointment only，或者要求只有固定的哪一天那个时候才能看房，做open home的时候你可以要求你也要在场的。
或者你们可以商量要求他给你做open home的那几周减房租。当然，房东可以选择不同意，你也能拒绝他做open home。
