Who regulates and what to file
An Authorized Person plans, constructs or supervises a sewerage system under the Sewerage System Regulation. That person files system information with the regional health authority before construction and a certification after completion. A holding tank follows a permit route under the regulation. A city building permit or zoning decision does not replace the health-authority filing.
Buying, alterations and maintenance
Ask the health authority for the filing, plans, certification and maintenance plan associated with the lot; verify that any later alteration is on file. The owner must maintain the system according to its plan. For a new bedroom, addition or replacement, give an Authorized Person the existing record and proposed use so the design flow and site can be reassessed. Provincial management guidance explains the filing and owner roles.
The city’s separate question
A city address does not prove the parcel is unsewered. Check utility/service records and any connection requirement with the municipality, then ask the health authority with jurisdiction for the onsite file. Municipal subdivision, building, land-use and watercourse restrictions can still affect a proposed location. Our city-area guides identify the available local and health-authority route; where only the provincial process could be verified, they are retained for navigation without separate search indexing.
BC’s regulation requires the owner to maintain the system according to its maintenance plan and keep maintenance records. After applicable construction, the owner is to receive the plans/specifications, maintenance plan and letter of certification; the health-authority filing also includes the as-built plan. Those documents are more useful than a generic pump receipt when buying or planning an alteration.
