What the 4th house is responsible for
The classical astrologers linked the fourth house with parents, above all the father, with land and real estate, with ancestors and inherited property. They also gave it “the end of the matter” — how everything ends, up to old age. It's the underground angle of the sky, and its meanings fit: foundation, the hidden, what everything else stands on.
Modern astrology made it the house of the inner rear: the atmosphere of childhood, the habits of the parental home, what later seems self-evident for life, and the place where you needn't keep a straight face. Also here — your own home and the family you build yourself.
The main dispute is about parents. In the classical tradition the fourth house is the father and the tenth the mother. Many modern authors swap them or speak of the caring parent in the fourth and the demanding one in the tenth, whoever they were. If you read parents from the chart, choose one scheme in advance: otherwise a fitting answer will always be found.
Analogy: Cancer and Moon
The fourth house is compared to Cancer, the sign of protection, and to the Moon — the planet of the sense of safety. The hint helps you remember the meaning, but doesn't make the fourth house “lunar” for everyone: for a person with Sagittarius on the IC the childhood home could have been open, noisy, with moves, and that is read from Sagittarius.
How to read the 4th house in your chart
The sign on the IC
The sign at the start of the fourth house is always opposite the sign of the Midheaven: MC in Capricorn — IC in Cancer. It describes the atmosphere of home: fire — noisy and lively, earth — solid and practical, air — conversations and guests, water — closeness and emotions, sometimes over the top.
The manner of each sign at the start of a house — on the pages of the zodiac signs.
Planets in the 4th house
Planets in the fourth house — what was tangible in the family: Saturn — strictness, duties, a shortage of warmth or money; the Moon — a strong tie to home as a place; Jupiter — a big family, a hospitable home; Uranus — moves and instability; Pluto — family secrets and one parent's strong power.
What each planet means and how to read it by house: Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.
The ruler of the 4th house
The ruler of the fourth shows where the roots reach: in the tenth — family and work are intertwined, from the family business to working from home; in the ninth — roots in another country or culture; in the seventh — the home is built around a partner.
If the 4th house is empty
An empty fourth house is not an empty childhood. In about half of charts it is empty, and family is then read from the sign on the IC, from the ruler and from the Moon.

How to check it on yourself
Each statement below may turn out to be false about you — that’s how it’s written. Check it against your past, and write your answer down before you compare it with the chart. The first item checks the calculation itself, the rest — the interpretation.
If your Sun is in the 4th house
What should match. Your birth time falls in the last third of the interval from sunset to true midnight — shortly before midnight. Sunrise and sunset for the day and city of your birth are in any astronomical calendar; true noon is exactly halfway between them, true midnight is twelve hours after noon.
When it’s not about you. The time on your birth record doesn’t fall in this window and is more than a quarter of an hour from its edge — then the wrong time, time zone or city went into the calculation, and the houses in the chart aren’t yours. This checks the calculation, not the interpretation.
If Saturn is in the fourth house
What should match. Childhood had a lot of duties and little ease: before age twelve you had constant duties around the house or for younger children — not one-off requests but something you were held to every day — or there was a strict regime at home.
When it’s not about you. Before age twelve you had neither constant duties nor a strict regime — a contradiction. It's better to check through other people's eyes: ask a brother, a sister or a parent what your home was like, without hinting at the answer.
If Uranus is in the fourth house
What should match. Roots didn't hold you in place: before eighteen there was at least one move with a change of school or city, or the family itself changed sharply — divorce, a new makeup, life between two homes.
When it’s not about you. One apartment and one school all through childhood, and a family without sharp changes — a miss.
