The 4th house sits at the bottom of a birth chart, and astrologers read it for what lies beneath the public surface: home, family, roots and private foundations. Here you will see where it sits, what two early authors listed, how guides read it now and how often planets land in it in our own sample. It is tradition for reflection, and it cannot be found without a birth time.
Where the 4th house sits: the bottom of the chart
The fourth house is the second of the four angular houses, and by the natural order of the wheel it echoes Cancer, the fourth sign. Alan Leo had that pairing in mind in 1903 when he told readers to “pay special attention to the corresponding house”. The angular group and the systems are in the houses guide.
It begins at the Imum Coeli, the IC, which Wikipedia describes as the point opposite the Midheaven, and which marks the fourth house cusp in most house systems. Guides describe the spot as the midnight point of the chart, and Astrology Zone says it is where the 6 would sit on a clock face. Wikipedia’s page on the point says the IC is said to refer to people’s roots and to the least conscious part of the self.
Wikipedia’s list of houses gives the house’s old Latin name as Genitor, glossed as Parent, and summarizes it as home, family and the emotional roots that provide stability. Houlding stresses its traditional place as the house of ancestry and heritage, and Rudhyar sees it as the inner sanctuary where identity is nurtured away from public view.
Residence and heredity in the early lists
Sepharial’s 1910 book Astrology: How to Make and Read Your Own Horoscope places “the residence” in the fourth house’s list, with property, the produce of the earth and the mother, and the list ends with the end of life, which modern astrologers read gently as endings in general. Alan Leo, in How to Judge a Nativity (1903), lists “Hereditary tendencies; home and domestic life”.
The two lists agree on the core: home and what is inherited. Neither describes an event that a chart holds.
Home, family and roots in current guides
Home, family and roots
Guides widely describe the 4th house as the house of home. Astrology.com calls it the House of Home and speaks of putting down roots. Astrology Zone lists the home residence and how a person feels about it, along with other property. Astrostyle says it rules roots and the roost, from the family of origin to home decor. Numerologist.com reads the house as the foundation a life is built on, some of it laid before a person was old enough to choose it.
Endings and where things settle
Two guides add a quieter theme. Astrology.com says the house brings things full circle by also addressing old age and endings. Astrology Zone speaks of the end of all matters, meaning the final settling of a situation. So when astrologers talk about endings here, they mostly mean how matters conclude and where they come to rest.
Which parent?
Astrostyle notes that the house is associated with caretakers, especially the mother in classical interpretations. Wikipedia’s IC page adds that there is no consensus in modern usage on which parent the point best represents. Our 10th house page records the same debate from the other side of the axis.
Under the 10th house
At the top of the wheel sits the 10th. One guide says the 4th lies directly across from it, hidden at the bottom of the chart, and treats the two as an axis of private foundation and public role.
What a planet at the bottom of the chart is said to do
Traditionally, astrologers treat planets in the angular houses as the most prominent in a chart, and one in the 4th is often described as shaping what is private and inward rather than what is on display. That is a convention about emphasis, and we give no verdict on any planet.
Empty 4th houses in our sample
The sample: 21,025 charts at 40.71 N, cast 1 day and 61 minutes apart between 1950 and 2009, using the Sun, the Moon and Mercury to Pluto. The 4th house held no planet in 47.4% of Placidus charts and 44.8% of Whole Sign charts, and three or more in 8.1% of Placidus ones. With 5.68 empty houses on average per chart, a blank 4th is an ordinary result.
The 4th house’s width across latitudes
Whole Sign keeps it at 30 degrees. Placidus lets latitude change it, and the 10th always shares its width. A complete turn of the sky gives these widths in degrees:
| Latitude | Narrowest | Average | Widest |
|---|---|---|---|
| The equator | 27.6 | 30.0 | 32.6 |
| Miami (25.8 N) | 24.0 | 30.0 | 34.4 |
| Los Angeles (34.05 N) | 22.4 | 30.0 | 35.5 |
| New York (40.71 N) | 20.9 | 30.0 | 36.7 |
| London (51.5 N) | 17.5 | 30.0 | 39.8 |
| 60 N (Oslo, Helsinki) | 12.7 | 30.0 | 44.6 |
The 4th changes shape less than the houses at the horizon: at 60 N it runs from 12.7 to 44.6 degrees, and in Los Angeles from 22.4 to 35.5.
Toward midnight: the Sun in the 4th house
Late in the evening the Sun stands here. In New York clock time under Placidus, for four days of 2000:
| Day | Sun in the 4th house (New York clock time) |
|---|---|
| March 20, 2000 (equinox) | 10:04 pm to 12:03 am |
| June 21, 2000 (solstice) | 11:28 pm to 12:57 am |
| September 22, 2000 (equinox) | 10:49 pm to 12:48 am |
| December 21, 2000 (solstice) | 9:26 pm to 11:54 pm |
The last slot: Placidus spreads houses 6, 5 and 4 over the run from sunset to local midnight, and the 4th closes it. June is on daylight saving time, and December ends a little before midnight on the clock. It is one city on four dates.
Same planets, Whole Sign houses
Of the planets in the Placidus 4th, 48.7% were in the 4th under Whole Sign too, 40.9% were in the 5th and 7.5% in the 3rd. The Sun was in the Placidus 4th in 8.3% of charts, a shade under the even-split 8.33%.
Spotting the 4th house on your chart
Your date, place and exact time go into a birth chart calculator, and the 4th house is the segment beginning at the bottom of the wheel. If nothing is in it, study the sign on its edge and the whereabouts of that sign’s ruler.
Before it on the wheel is the 3rd house, after it the 5th house. For a route through a full chart, see how to read a birth chart.
Questions about home and roots
Consider these as prompts only.
- What is the first thing that makes a place feel like home to you?
- Which habits or traditions from where you grew up are still part of your days?
- Where do you go to feel most like yourself when no one is watching?
Questions people ask
Astrologers read the 4th house for home and roots: the place you live, your family of origin, heritage and the private foundations of a life. It is an angular house and, in the natural order of the wheel, echoes Cancer, the fourth sign. It describes themes for reflection and makes no promise about a person's home.
Tradition leans toward the mother: older lists, and several modern guides, link the house with the mother or the nurturing parent. Wikipedia's page on the Imum Coeli notes that modern astrologers do not agree on which parent the point represents, and some use it for the father or for both.
Nothing is missing. In our sample of 21,025 charts at 40.71 N, 47.4% had no planet in the 4th house under Placidus and 44.8% under Whole Sign. Astrologers read an empty house through the sign on its edge, which for the 4th is the IC sign, and through the planet that rules that sign.
By the natural order the 4th house echoes Cancer, and Astrology Zone names the Moon as its natural ruler. Sepharial, in 1910, wrote that the Moon governs Cancer. For your own 4th house, the ruler that matters is the planet of the sign on its edge, which may be any planet.
For many planets. Of the planets we found in the Placidus 4th house, 48.7% were also in the 4th under Whole Sign and 40.9% had moved to the 5th (21,025 charts, 40.71 N). A planet well away from a house edge stays put. Compare both systems in a chart calculator.
Astrologers also read the lunar nodes by house. See the North Node in the 4th house, with the South Node in the house opposite.
