Renting rooms

[kwtim]

My mother owns and occupies a house in a subdivision in Harris County,Texas in which she rents rooms. The deed restrictions in her subdivison state that no homeowner may operate a business from home that "invites the public" or is "an annoyance or nuisance". She has responded to a HOA complaint filed by her new next door neighbor about these activities. She has lived peacefully in this house for 26 years and most of the other neighbors do not have a problem with her activities. An HOA complaint from ten years ago on this issue was not pursued by the HOA attorney, using the same deed restrictions. If she was able to obtain signed affidavits stating they do not find this activity to be an annoyance or nuisance from an overwhelming majority of her neighbors, would that be enough to counteract single complaint filed by this neighbor? And does renting rooms constitute inviting the public?
