A Sydney mother has received a letter from her apartment building's strata company telling her that she needs to control her toddler from making “excessive noise” otherwise they may take legal action.

Janin Mayer, 33, has been living in the two-bedroom Vaucluse apartment with her 19-month-old child Elliav and her husband Evi, 35, since December and pays $560 a week in rent.

The infuriated mother posted the letter she received from Bright & Duggan on Facebook which claims she and her toddler are "disturbing other residents".

Ms Mayer is pregnant with her second child and said she feels threatened by the distressing tone of the letter.

“Living harmoniously within a strata scheme requires all occupiers to be aware and considerate of each other,” it reads. “Strata by-laws are adopted to give guidance and outline the standard of behaviour expected to ensure that all residents enjoy a peaceful existence," the letter reads.

“It has been brought to our attention that excessive noise, in the form of your child shouting and screaming, is emanating from your apartment from early in the morning to very late at night on a regular basis.

"This is disturbing other residents and as such you are in breach of the strata scheme by-laws.

“Please refrain from allowing your child to create excessive noise immediately and into the future. You must be mindful of other residents and keep noise levels to a minimum at all times.

“Continued breaches of the by-laws may result in the matter being taken further and a fine of $550 being imposed by the NSW Civil & Administrative Tribunal.”
