Building lots and coastal land: what has to be true before it is buildable

Subdivision approval

Under the provincial Subdivision and Development Regulations, no one may subdivide land without final approval from the Minister. Ask whether the lot is an approved parcel with its own PID, and get the survey. Municipalities with their own official plan and bylaws run their own approvals.

Site suitability (the “perc test”)

Before a septic system can be approved, a licensed site assessor, an engineer, or an environment officer assesses the lot and assigns it a lot category. The category affects which systems are allowed and what they cost. A category is not a building permit.

• Ask for the site assessment and the lot category
• Get a septic installer’s estimate for that category

Shoreline and watercourse setbacks

Where the provincial regulations apply, a building on a beach has to be set back at least 75 feet (22.9 m) from the top of the bank, or 60 times the annual erosion rate for that area, whichever is greater. It has to be 100 feet (30.5 m) from a migrating sand dune and 75 feet from a wetland or watercourse. New coastal subdivisions also need a buffer of at least 60 feet (18.3 m), or 60 times the erosion rate. The province can require more.

Separately, most work within 15 metres of a watercourse or wetland needs a buffer zone activity permit. On an eroding bank, the area you can build on can be smaller than the lot looks, and it can shrink.

Water

You are drilling for water you have not seen. The province recommends testing a new well for chemistry and testing for bacteria at least once a year. Islanders with residential wells can get free bacterial and general chemistry tests through the PEI Analytical Laboratories.

Access and power

A new driveway onto a provincial highway needs an entrance way permit from the province. Deeded access, private road maintenance, and the distance to power all change the budget. Budget each item separately from the lot price.
