What sets St Marys apart

A town since the 1840s

St Marys took its name when its post office opened in 1840, closer settlement followed an 1842 subdivision, and the municipality was proclaimed in 1890.

Split by the railway

The north, around Dunheved, is mostly industry and trade businesses. The south is where most people live, around Queen Street.

Semis and units

In 2021, 51.2% of homes were separate houses, 30.0% semi-detached houses or townhouses and 18.5% flats.

Endeavour Energy, and a solar change

Penrith is in Endeavour Energy's area, so outages go to 131 003. Postcode 2760 is in stage 2 of Endeavour's flexible exports rollout from 30 November.

For St Marys landlords

Under NSW minimum standards, a rental needs enough electricity or gas outlets for lighting, heating and appliances, and adequate lighting in every room except storage rooms and garages.

Smoke alarms must be checked every year, removable batteries replaced every year, and the alarms themselves replaced within 10 years of manufacture.

The condition report at the start of each tenancy records whether there's a safety switch and whether it works. Testing it is the only way to know.

Paperwork worth keeping for each rental

  • A CCEW for every electrical job; the electrician must lodge it within 7 days of finishing
  • The date of each year's smoke alarm check
  • The manufacture date of each smoke alarm
  • The safety switch result on each condition report
  • The electrician's licence number, checked on Service NSW

Where we'd start

For a semi or townhouse that's been rented out for years, book one inspection that covers the switchboard, the safety switches and the smoke alarms together. It's the simplest way to know the place meets the rules before something fails. Where we've got a licence-checked electrician nearby for that kind of job, we'll match you.
