Housing

Sydney surpasses both New York City and Paris real estate prices, having some of the most expensive in the world. The city remains Australia's most expensive housing market, with the mean house price at $1,142,212 as of December 2019 (over 25% higher the national mean house price). It is only second to Hong Kong with the average property costing 14 times the annual Sydney salary as of December 2016.

There were 1.76 million dwellings in Sydney in 2016 including 925,000 (57%) detached houses, 227,000 (14%) semi-detached terrace houses and 456,000 (28%) units and apartments. Whilst terrace houses are common in the inner city areas, detached houses dominate the landscape in the outer suburbs. Due to environmental and economic pressures, there has been a noted trend towards denser housing, with a 30% increase in the number of apartments between 1996 and 2006. Public housing in Sydney is managed by the Government of New South Wales. Suburbs with large concentrations of public housing include Claymore, Macquarie Fields, Waterloo, and Mount Druitt.

A range of heritage housing styles can be found throughout Sydney. Terrace houses are found in the inner suburbs such as Paddington, The Rocks, Potts Point and Balmain, many of which have been the subject of gentrification. These terraces, particularly those in suburbs such as The Rocks, were historically home to Sydney's miners and labourers. In the present day, terrace houses now make up some of the most valuable real estate in the city. Surviving large mansions from the Victorian era are mostly found in the oldest suburbs, such as Double Bay, Darling Point, Rose Bay and Strathfield.

Federation homes, constructed around the time of Federation in 1901, are located in a large number of suburbs that developed thanks to the arrival of railways in the late 19th century, such as Penshurst and Turramurra, and in large-scale planned "garden suburbs" such as Haberfield. Workers cottages are found in Surry Hills, Redfern, and Balmain. California bungalows are common in Ashfield, Concord, and Beecroft. Larger modern homes are predominantly found in the outer suburbs, such as Stanhope Gardens, Kellyville Ridge, Bella Vista to the northwest, Bossley Park, Abbotsbury, and Cecil Hills to the west, and Hoxton Park, Harrington Park, and Oran Park to the southwest.
