Identify connection points with a source
Record where each proposed connection is, who identified it and which drawing or authority record supports it. A pit seen in a photograph is not automatically a suitable connection point. Mark inferred locations as inferred. Give the practitioner the source material rather than a redrawn map that conceals uncertainty.
Levels and routes come before a connection price
A short plan distance can conceal a level change, an existing structure, a protected asset or a difficult excavation. Ask the designer and licensed practitioner to establish the route and any additional equipment or authority process it needs. Carry unresolved work as a separate scope item rather than assuming a standard connection price applies to every backyard.
“The register is the one reference a builder cannot hand you. Read it before you read the price.”
Metering is both a physical and an operating decision
Discuss whether supplies are independent or shared, where meters and isolators will sit, who can access them and how the future tenancy will operate. A privately installed submeter and a separately billed authority supply are not interchangeable descriptions. Rental charging rules should be checked separately by the property manager; design convenience does not establish a lawful billing arrangement.
Protect the existing household during works
Document any shutdown, temporary service, trench crossing, shared access and reinstatement. Ask who communicates with occupants and who confirms the original house’s service remains functioning after the new connection. These details matter whether the new dwelling is for family use or a separate tenancy; they do not disappear because the building is made off site.
Close the brief with completion evidence
Collect the relevant test, inspection and compliance documents, updated locations and equipment details. A photo of a tap running is useful but does not replace required practitioner documentation. Keep service completion, building occupation and rental readiness distinct. Review the handover pack with the builder and manager before arranging occupation.
Questions people ask
Does an existing sewer mean connection is easy?
Not necessarily. Its location, level, condition, capacity and the permitted connection need review. Provide the authority information and surveyed levels to the relevant practitioner before relying on a route or quote.
Can service routes be priced from aerial imagery?
Imagery may help an early discussion but cannot confirm buried assets, levels or capacity. Label an image-based price as an assumption and identify the survey, practitioner inspection or authority response needed to resolve it.
Does no planning permit mean no services approvals?
No. A planning pathway is separate from building and service requirements. The small second dwelling guide expressly requires a building permit [5]. Confirm the connection process with the relevant authority and licensed practitioner for the actual site.
Should metering be left until handover?
It is better resolved in the design and operating brief. Meter location, access, isolation and billing arrangements affect installation and management. A late decision can create additional work or an unsuitable tenancy arrangement.
Who restores trenches and damaged landscaping?
The contract scope should name the party and define the restoration standard. Do not assume it is included in a supply-and-connect description. Add paths, fences and existing-house protection where those are affected.
What evidence should reach the property manager?
Provide service locations, isolation instructions, warranties, relevant practitioner documents and the final metering arrangement. The manager should separately assess applicable rental obligations. Keep personal account credentials outside public project and marketing material.
