The 4th House
The House of Home and Family · angular · natural sign Cancer
The 4th house is the house of home and family, covering your roots, your private life, one of your parents traditionally, and the place you retreat to at day's end.
The 4th house sits at the very bottom of the chart, beginning at a point called the IC, short for Imum Coeli, the lowest stretch of sky at your birth. Because it lies beneath the horizon, out of sight, astrologers read it as the hidden foundation of a life. It covers home, family, ancestry, and your sense of belonging, and in traditional astrology it represents one of your parents. It is where you come from, in every sense, and the private ground the rest of the chart stands on.
Planets in the 4th house are read as shaping your experience of home and your emotional roots. The Moon is considered especially comfortable here, and a person with this placement is often described as deeply attached to family, their sense of security rising and falling with the atmosphere of the household. Saturn in the 4th appears in readings as a stricter or more burdened experience of early home life, and later a serious dedication to building a lasting one. Astrologers also watch this house when questions of settling down arise.
Whether any planet occupies your 4th house depends on your precise birth time and place, because the houses are fixed to the horizon of that moment while the rotating sky carries every planet through all twelve houses each day — a chart cast at noon and one cast at midnight put the same planets in very different houses. As an angular house anchored to the IC, the 4th is considered foundational and powerful despite its privacy. Its natural sign is Cancer, ruled by the Moon, which gives it a protective, nurturing, memory-keeping character.
Common questions
What is the IC in astrology?
IC stands for Imum Coeli, Latin for the bottom of the sky. It is the point opposite the Midheaven, where the ecliptic crosses the meridian below the horizon, and in most house systems it forms the cusp of the 4th house. Astrologers treat it as the root of the chart, describing origins, family inheritance, and your deepest sense of home.
Which parent does the 4th house represent?
Traditions disagree, which is worth knowing before anyone tells you a single answer. Older sources typically assign the father to the 4th house, while much modern astrology gives it to the mother, or to whichever parent shaped your sense of home most. Many working astrologers now sidestep the debate and read the 4th and 10th as a parental axis, letting the chart and the conversation decide.
Which planets are in your 4th house?
Houses turn with the sky, so only your exact birth time can answer that. The chart builder shows your houses forming as you add each piece of birth information — uncertainty drawn honestly.
