Tentant wants do the fence replacement

[Don Chen]

Dear BP Landlords,

I have a tenant that presented me with an unusual request about the doing improvements on fence at a part of duplex that I rent out to him. The fence is ok shape currently.  The fence post are still sturdy.The fence pickets may need to be replace in the near future.  My tenant tells me he used to own a fence building company for 15 years.  He has some ideas on how he wants to do fence work.  He offer to do the labor and all I have to do pay for the materials.  He will provide me estimate of material cost before so I can give the final ok to proceed.   I am concern about the personal injury liability issue and express the concern to my tenant.He express to me he really want to do this job and he is willing to sign a personal waiver if I let him to do fence replacement.  I am not sure if I should let him to this fence work, given that I am ok with cost of material. Part of me want to let him do the fence work and if he is ok on replacing the fence picket on the other side of the duplex as well.  So I can improve property at not pay for the labor of work.  I inherited this tentant from the previous owner of this property.   So far this tentant have been paying rent on time.  

I would like to get some feedback from the landlords out there what is the best way to handle this special situation.

Thanks,

Don
