I received a legal letter from my downstairs neighbor for noise

If you would like me to review the letter and suggest what you should do, please email it to me at ds@sackrosendin.com or fax it to me at 510-286-8887. Is the neighbor complaining about footsteps, music, television, or something else? Is this a condominium or an apartment? Are you an  owner or a renter? Is the neighbor an owner or a renter? Have you recently installed a wooden floor or vinyl floor? If it is a condominium and you recently installed a wooden floor, did you get the prior written approval of the HOA? Did you install sound insulation under the floor? Lots of information and legal issues to talk about. Dana Sack
