Rent Discount for Construction?

[Nicole Oka]

Hi All,

I am renting out a condo in San Jose for $2,900/m and the HOA is currently doing major construction on the stairways. The project is incredible loud (tenants sent me a video) and is estimated to take 3 weeks to complete. Normally I don't think it would be so bad because the tenants would be at work, but given that they are working from home, they have to deal with this all day long.

They have asked for a discount on June's rent, which I agree is fair considering what they're dealing with (they just moved in in April and feel like they should have been warned about the project before signing the lease). 

What do you think a fair amount to discount is?

Thanks for the advice!
Nicole
