Yes. St. John's is known for its hard rock (shale and sandstone). If a new pit must be excavated, contractors often charge a premium of $500 to $1,200 specifically for rock breaking and removal compared to standard soil.
Highly recommended. Due to frequent high-wind storms and power outages in NL, a battery backup system (costing an additional $600–$1,100) is standard for local waterproofing to prevent basement flooding during outages.
A plumbing permit is required for any new connection to the city's sewer or storm system, costing approximately $21.12 for the connection fee plus potential inspection fees. Electrical permits are also required if a new dedicated circuit is installed.
In St. John's, discharge lines must be buried below the frost line (typically 4 feet) or equipped with an 'IceGuard' type fitting to prevent the line from freezing and backing up, which can add $150–$300 to the material cost.
