About City of Saint John Homes
Development Era
1780-present
Peak building: 1880-1910 (post-fire rebuild) and 1950-1970
Typical Styles
- Loyalist and Georgian row house (Uptown)
- Second Empire Victorian (South End)
- Post-fire Italianate and Queen Anne (throughout)
- Post-war bungalow (Millidgeville, East Side)
- Multi-unit row house and flat (North End)
Average Home Size
1,000-3,500 sq ft
Saint John's heritage housing stock is electrically demanding. Uptown row houses typically share party walls and may have shared or unclear electrical separation between units. South End Victorians are large (2,500-3,500 sq ft) with complex multi-storey wiring challenges. North End multi-unit buildings may have improvised electrical divisions from decades of conversion between single-family and multi-unit use. The post-fire 1880s-1910s homes that form the city's core were electrified with knob-and-tube and many still carry this original wiring alongside later additions. Post-war suburban areas (Millidgeville, East Side, Crescent Valley) have more conventional 1950s-1970s electrical but still frequently need panel upgrades.
Area History
Saint John's electrical history is uniquely complex. The oldest homes predate commercial electricity by over a century — Loyalist-era homes in Uptown were retrofitted with gas lighting in the 1850s and then electrified in the 1890s-1910s, often with wiring run through gas pipe conduits. The Great Fire of 1877 destroyed much of the city's core, and many replacement homes from the 1880s-1890s were among the first in NB to receive knob-and-tube wiring. The result is layers of electrical history in a single home — original gas pipe conduit, knob-and-tube from the early 1900s, cloth-insulated copper from the 1940s, and modern NMD90 patches from partial upgrades. The Bay of Fundy's extreme tidal environment creates persistent salt air that corrodes outdoor electrical infrastructure faster than anywhere else in New Brunswick. NB Power's Saint John infrastructure includes both overhead and underground distribution, with the underground system in Uptown being among the more reliable in the province but older overhead lines in North End and East Side being vulnerable to storms.
Foundation Types in City of Saint John
Heritage foundations in Saint John create significant electrical challenges. Cut stone foundations in Uptown row houses are often damp and uneven, making panel mounting and cable routing difficult. Many heritage homes have panels in inappropriate locations — damp basements, closets, or under stairs — that do not meet modern CEC clearance requirements. Rewiring heritage homes requires creative routing through plaster walls, balloon-framed cavities, and stone foundation walls. Post-war suburbs have standard concrete or block foundations with conventional electrical routing.
Common Issues to Address
- Damp stone foundations corroding panel enclosures and ground connections
- Heritage homes with panels mounted in locations that violate CEC clearance requirements
- Balloon-frame construction allowing fire spread along electrical pathways between floors
- Stone and brick foundations making new cable routing extremely difficult without surface conduit
- Shared party walls in row houses complicating electrical separation between units
Soil & Drainage in City of Saint John
Soil Type
Bedrock with thin till cover (urban core), marine clay (harbour flats)
Water Table
Variable — bedrock areas well-drained, harbour areas high water table
Saint John's geology is challenging for electrical grounding. The urban core sits on bedrock with thin till cover, where standard ground rods may not achieve adequate resistance without supplemental grounding (Ufer ground connections to concrete-encased rebar or metal water pipes). Harbour-adjacent properties in the North End and Lower West Side have marine clay with salt content that provides good conductivity but accelerates corrosion on copper ground rods and buried metallic components. The tidal influence from the Bay of Fundy means groundwater levels fluctuate significantly.
Drainage: Heritage homes in lower Saint John (Waterloo Village, parts of North End) are prone to foundation flooding during spring tides and heavy rain. Sump pump circuits with battery backup are essential in these areas. Panel placement above the high-water mark is critical in flood-prone properties. GFCI protection on all below-grade circuits is mandatory.
Investment Potential in City of Saint John
Average Home Price
$150,000-$350,000
Electrical Upgrade ROI
In Saint John's affordable market, electrical upgrades can represent a larger portion of home value but also have outsized impact on insurability and saleability — a home that cannot obtain insurance due to knob-and-tube or a Federal Pacific panel is essentially unsellable
Saint John's real estate market is among the most affordable in southern Canada, which makes electrical upgrades relatively expensive compared to property values. However, the impact is critical — insurance companies are increasingly refusing to cover homes with knob-and-tube wiring, Federal Pacific panels, or visible electrical hazards. A complete rewiring project ($15,000-$25,000) on a $175,000 heritage home may seem disproportionate, but it makes the property insurable, mortgageable, and saleable. For investment properties, electrical upgrades enable rental income that quickly recoups the cost.
Electrical Considerations for City of Saint John
Heritage home rewiring in Saint John often involves working around lath-and-plaster walls, original hardwood floors, and ornamental woodwork — experienced heritage electricians can minimize wall damage by routing through existing cavities, attic spaces, and basement joist bays
Knob-and-tube wiring is extremely common in pre-1945 Saint John homes and is increasingly required to be removed (not just disconnected) for insurance compliance — budget $8,000-$25,000 for removal depending on home size
Bay of Fundy salt air corrodes outdoor electrical components — all service entrances, meter bases, and outdoor fixtures in Saint John should use marine-grade or NEMA 4X rated enclosures
Multi-unit buildings converted from single-family homes may have unsafe or non-code-compliant electrical separation — TSANB inspection can identify hazards and required upgrades
TSANB permits are required for all electrical work — heritage district regulations in Uptown and South End may add requirements for visible exterior electrical components
NB Power service entrance upgrades in Uptown may involve underground connections — coordinate with NB Power and the city for dig permits and scheduling (6-8 week lead time)
Federal Pacific and Zinsco panels are common in 1960s-1980s Saint John homes and should be replaced due to documented fire hazards — combine with a panel upgrade for best value
Row house electrical separation projects (common in Uptown and North End) require careful load calculation and may need individual NB Power service connections for each unit
Permits & Regulations
All electrical work in Saint John requires TSANB (Technical Safety Authority of New Brunswick) permits and inspections. The City of Saint John building inspection department handles structural permits and coordinates with TSANB on heritage district requirements. Uptown and South End heritage conservation areas may have additional requirements for visible exterior electrical components (service entrance placement, meter location, outdoor conduit routing). Contact TSANB at 1-800-999-0813 or visit tsanb.ca. Heritage property owners should also consult the City of Saint John Heritage Development Board before any exterior electrical modifications.
Frequently Asked Questions: City of Saint John Electrical
How much does it cost to rewire a heritage home in Saint John?
Complete rewiring of a Saint John heritage home typically costs $15,000-$30,000 depending on home size, number of floors, and accessibility. A 2,000 sq ft Uptown row house averages $15,000-$20,000, while a 3,500 sq ft South End Victorian can reach $25,000-$30,000. This includes: removing all knob-and-tube and old wiring, installing a new 200A panel, running NMD90 copper circuits throughout, installing grounded outlets, adding GFCI/AFCI protection, and coordinating with NB Power for service entrance work. Heritage-sensitive techniques (fishing wire through existing cavities to minimize wall damage) add 15-25% but preserve original plaster and woodwork.
Will my insurance cancel if I have knob-and-tube wiring in Saint John?
Increasingly, yes. Many NB insurance companies now require removal of knob-and-tube wiring — not just a report saying it is safe. Some specialty insurers still cover homes with knob-and-tube at higher premiums ($500-$2,000+ per year above standard rates), but options are shrinking. Your best approach: 1) Get a professional assessment from a licensed electrician to document the extent and condition of knob-and-tube, 2) Obtain a TSANB inspection report, 3) Present findings to your insurer, 4) Budget for partial or complete removal. Many electricians offer phased rewiring plans to spread the cost over 1-2 years.
Why is the electrical corroding on my Saint John house?
Bay of Fundy salt air is the primary culprit. Saint John's coastal location means persistent marine humidity and salt content in the air that aggressively corrodes standard electrical hardware — service entrance cables, meter bases, outdoor receptacles, and light fixtures. Homes closer to the harbour and on the West Side (directly exposed to the bay) experience the worst corrosion. Solutions: replace outdoor components with marine-grade or NEMA 4X rated equipment, apply dielectric grease to all connections, use stainless steel hardware, and schedule annual inspection of outdoor electrical components. Budget for 15-25% higher material costs but dramatically longer service life.
Can I separate the electrical in my Saint John row house into individual units?
Yes, but it requires careful planning and significant investment. Row house electrical separation typically involves: 1) Individual TSANB permits for each unit, 2) Separate NB Power service connections or sub-metering ($2,000-$5,000 per unit for NB Power connection), 3) New panels for each unit ($2,500-$4,000 each), 4) Rewiring to ensure no shared circuits between units ($5,000-$15,000 depending on complexity). Total cost for a typical 2-unit Uptown row house: $15,000-$30,000. This work is essential for legal rental compliance and proper billing. Your electrician coordinates with TSANB and NB Power throughout the process.
About City of Saint John
Saint John is Canada's oldest incorporated city (1785) and New Brunswick's largest city, situated on the Bay of Fundy with the world's highest tides. The port city's industrial heritage includes the Irving Oil refinery and shipbuilding history. NB Power's urban infrastructure is a mix of underground distribution in Uptown (reliable) and aging overhead lines in residential areas (vulnerable to storms). The Bay of Fundy's extreme tidal environment creates persistent salt air that affects all outdoor electrical components. The city's heritage districts in Uptown and South End contain some of the most architecturally significant (and electrically complex) buildings in Atlantic Canada. Saint John's colder, foggier microclimate compared to inland NB means higher humidity exposure for electrical systems year-round.
