Sydney Stormwater Bylaws for Homeowners

Environmental Protection New South Wales 3 Minutes Read · published February 11, 2026

Sydney, New South Wales homeowners must manage on-site stormwater to protect public drains and waterways. This guide explains who is responsible, common obligations under local controls, enforcement pathways, and practical steps to reduce flood and pollution risk for houses, driveways and gutters.

Who must comply

Owners and occupiers of residential properties in the City of Sydney are responsible for preventing stormwater pollution, ensuring lawful connections to public drainage, and maintaining drainage on their land. Building and subdivision work that changes runoff typically requires approval under local planning controls and may need conditions to control stormwater.

Check approvals before altering drainage lines on your property.

Penalties & Enforcement

Stormwater pollution and unauthorised works can attract council enforcement and state environmental action. Where the City of Sydney enforces by-laws or development conditions, the council’s compliance and by-law teams are the primary enforcers; state agencies handle pollution that affects waterways.

Fine amounts: not specified on the cited page.^[1]
Escalation: first, repeat and continuing offences are managed under council enforcement policy and state environment law; specific dollar ranges are not specified on the cited page.^[1]
Non-monetary sanctions: orders to stop works, rectification notices, prevention notices, seizure of equipment and prosecution through courts where serious pollution occurs.
Enforcers and complaints: City of Sydney By-law Enforcement and Compliance teams, and NSW Environmental Protection Authority for pollution incidents; report via council complaint pages or the EPA incident reporting process.^[1]
Appeals and review: decisions and notices by the council are typically appealable to the NSW Civil and Administrative Tribunal or relevant court; time limits for appeal depend on the notice type and are not specified on the cited page.^[1]
Defences and discretion: councils may allow works under approved permits, compliance agreements or with reasonable excuse defences where expressly provided in legislation or policy; specifics are not specified on the cited page.^[1]

If your work affects drainage, get written approval first.

Applications & Forms

Council and state agencies use different forms for works and pollution reporting. For typical building or drainage alterations, a development application or a works-in-public-place permit may be required; specific form names, numbers and fees vary by application and are not listed on the cited page.^[1]

Common violations

Illegal connection of roof or yard runoff to sewer or unauthorised alteration of a public stormwater pit.
Uncontrolled construction sediment and wash entering gutters and waterways.
Discharge of pollutants (fuels, paints, garden waste) to stormwater.

Document compliance steps and keep records for inspections.

Practical action steps

Before work: check whether a development application or works permit is required with the City of Sydney.
On site: use sediment controls, shut off connections before works, and prevent pollutants leaving the property.
To report: contact City of Sydney compliance or report pollution to the NSW EPA if waterways are affected.
If issued a notice: follow rectification directions, seek review or lodge an appeal within the statutory time limit shown on the notice or relevant legislation.
