Chandu Menon was born on 9 January 1847 in Naduvannur near Perambra in the present day Kozhikode District. His family moved to Thalassery when he was an infant.
Chandu Menon got his first lessons from Koran Gurukkal, one of his neighbors. He learnt Sanskrit poetry, drama and grammar from Pandit Kunjanbu Nambiar. About the same time, he received English lessons from a local school and later from K. Kunjan Menon. He had higher school education in the Basel Evangelical Mission Parsi High School in Thalassery. While studying there he is reported to have qualified for the uncovenanted Civil Service by securing a high rank in the test for that Service. In 1857, his 52 year old father died due to diabetes. In 1864 his mother died when he was in the matriculation class and he was forced to abandon studies.
Chandu Menon married Lakshmikutty Amma in 1872. The couple had six children.
Chandu Menon started his career as a clerk in the government service. William Logan, author of the Malabar Manual appointed him as a clerk at Sub-Collector's office. After working in various offices in Malabar, he slowly rose to the position of a Munsiff, and in 1892 became the sub-judge of Calicut. As per a record available, he was also District judge of Mangalore in 1895. Chandu Menon reportedly assisted Willam Logan in the preparation of Malabar Manual.
Chandu Menon was also a social reformer. He was a member of the committee constituted to inquire on Marumakkathayam and report on the Malabar Marriages Bill. His observations on matrimony among Nairs that prevailed during the time are of historical importance. He was given the title of Rao Bahadur in 1898 for excellent service.
