Short answer: Book a regular home inspection, then add the specialists a lakefront home needs: a marine or dock contractor, a septic inspector, a water test (if the home isn't on municipal water), a geotechnical engineer for steep lots or retaining walls, a BC Land Surveyor to confirm the natural boundary, and an electrician for dock and boathouse wiring.
Your waterfront inspection team
| Specialist | Why you need them |
|---|---|
| Home inspector (licensed in BC) | The house itself: structure, roof, systems, moisture |
| Marine or dock contractor | Piles, floats, decking, lift motor and cables, ice and wave damage |
| Registered septic practitioner | Tank and field condition, distance from the lake, records |
| Water lab and treatment technician | Bacteria and chemistry testing; filters, UV and intake condition |
| Geotechnical engineer | Slopes, tall or tiered retaining walls, seawalls, erosion |
| BC Land Surveyor | Where the natural boundary is today, and any encroachments on Crown land |
| Licensed electrician | Dock, lift, boathouse, pump house and hot tub wiring |
| Qualified Environmental Professional | Only if you plan to build or change anything near the water |
The checklist
The dock and foreshore
- Type of authorization (General Permission, Specific Permission or lease) and proof of when the dock was built. See the dock guide.
- Condition of piles, floats, decking, ladders and anchor lines
- Boat lift: motor, cables, cradle, and water depth at low water
- Anything on the foreshore that isn't allowed: roofs, sun decks, hot tubs, fill, groynes or beach sand below the natural boundary
The shoreline and slope
- Retaining walls, seawalls and rip-rap: height, drainage, leaning or cracking, and whether they were engineered
- Signs of erosion at the toe of the bank, slope creep or past slides
- Stairs and paths to the water, and whether they needed permits
Flood and moisture
- Main-floor elevation compared with the flood construction level. See the flood guide.
- Evidence of 2017 or 2018 flood damage and repairs
- Foundation moisture, efflorescence and mould on the lake side
- Perimeter drains, sump pumps (with backup power) and backwater valves
- Humidity in lower levels and boathouses
Water and septic
- Municipal water, lake intake or well? For an intake: the line, foot valve, pump house, heat tracing and winterization, and the treatment system (filters, UV, chlorination)
- A water test at an approved lab
- Septic: the tank pumped and scoped, the field located, and the distance to the lake measured (at least 30 m is required for the dispersal field on newer systems). See the water and septic guide.
Electrical near the water
- Ground-fault protection on all dock, boathouse and shore-power circuits (the electrical code requires it)
- Permits for any dock or pump-house wiring. Unpermitted DIY dock wiring is common, and electric-shock drowning is a real hazard.
- Hot tub bonding and clearances
The paperwork
- A survey showing the present natural boundary compared with the titled boundary
- Covenants on title: flood, geotechnical or environmental
- Permits for past additions, walls, docks and shoreline work
- A water licence, if the home uses lake water under a licence. The seller must notify the Province before completion.
- Insurance quote with overland flood and dock coverage
Timing tip: waterfront inspections take longer to book, especially in spring and summer. Build extra days into your subject period, and try to see the dock and shoreline at a lower lake level if you can.
Frequently asked questions
Does a regular home inspector check the dock?
Usually not in any depth. Hire a marine or dock contractor to inspect the dock, lift and any shoreline structures.
Why do I need a survey for a waterfront home?
A BC Land Surveyor can confirm where the lake's natural boundary is today and whether walls, patios, beaches or docks sit on Crown land, which the Province can order removed.
How far does a septic field have to be from the lake?
Under BC's sewerage standards, a septic dispersal field must be at least 30 m from a permanent fresh water body, measured from the mean high water mark. Older systems may not meet this.
