The Cost of Owning a New Home in Sydney: Rates, Strata, Utilities and Build-Stage Payments Explained

Buying a new property in Sydney — whether a house-and-land package, a townhouse, or an apartment in a strata scheme — comes with several categories of ongoing cost beyond the purchase price and mortgage. These costs vary by council area, property type, and land value, so this article explains what each charge covers and what causes it to move, rather than suggesting a figure any particular buyer should plan around. Council rates Council rates fund local government services such as waste collection, local roads, parks, and community facilities. In NSW, the amount a council can increase its total rates income each year is capped by the Independent Pricing and Regulatory Tribunal (IPART) through an annual "rate peg." For the 2026–27 financial year, IPART set core rate pegs ranging from 2.5% to 4.2% across the state's 128 councils, before adjustments for population growth in individual council areas. This peg limits how much a council's total rates revenue can grow — it is not a fixed dollar figure applied to every property, since individual rates are also affected by each property's land value as assessed by the NSW Valuer General. Because land values and council budgets differ significantly between local government areas, rates on a comparable new dwelling can vary widely depending on which Sydney council area the property sits in. Strata and owners corporation levies If the new property is a unit, townhouse, or any dwelling in a strata scheme, owners pay strata levies in addition to council rates. Under the Strata Schemes Management Act 2015, these levies are split into two funds: an administrative fund covering day-to-day costs such as cleaning, common-area insurance, and minor repairs, and a capital works fund (formerly called the sinking fund) that accumulates money for major, infrequent works such as roof replacement or lift upgrades. NSW Government guidance confirms that all schemes must maintain a 10-year capital works fund plan, and from April 2026 new and reviewed plans must use a new standard form. Levies are set at the annual general meeting, calculated in proportion to each lot's unit entitlement, and owners must be given at least 30 days' written notice of amounts due. Because a new-build strata scheme is starting its capital works fund from scratch, early-year contributions and the adequacy of the 10-year plan are worth understanding at purchase, since underfunded capital works funds are a common cause of unexpected special levies later. Utilities Ongoing utility costs for a Sydney property include a fixed service charge plus a usage-based charge for water and wastewater, billed by Sydney Water, alongside separately metered electricity and gas. Sydney Water publishes residential fixed and usage charges that apply for each financial year (new prices took effect from 1 July 2026, within the current five-year pricing determination set by IPART for 2025–30). These are separate from any one-off developer or connection charges that may apply during a new estate's construction, which are distinct from a homeowner's ongoing utility bill. Land tax Land tax is a NSW state tax on the unimproved land value of property owned above a threshold, assessed by Revenue NSW as at midnight on 31 December each year. It does not apply to a person's principal place of residence, provided occupancy requirements are met. For the 2026 land tax year, Revenue NSW has confirmed the general threshold at $1,075,000, with thresholds frozen since 1 January 2025 under a 2024–25 NSW Budget change. This is relevant primarily to investment properties, holiday homes, or land not used as a principal residence — not to an owner-occupied home, which is generally exempt. Build-stage payment costs For a new house or house-and-land package still under construction, cost of ownership begins before the home is complete, through progress payments. Under NSW Government rules for residential building contracts over $20,000, the maximum deposit a builder can request is 10% of the contract price, and the contract must include a progress payment schedule tied to defined, completed stages of work — payments cannot simply be for time worked. This structure is designed to prevent buyers paying ahead of the value of work actually completed on site. Verify your own circumstances: council rates, strata levies, utility charges, and land tax liability all depend on the specific property, its location, its land value, and individual ownership circumstances. This article explains what drives each type of cost; it is not a substitute for checking the current charges that apply to a specific property with the relevant council, strata manager, utility provider, or Revenue NSW.
