Grand Bay-Westfield & West Side Housing Stock & History
Grand Bay-Westfield's housing stock divides into two distinct categories defined by elevation. The river-adjacent properties — cottages, bungalows, and homes built along the Saint John River shoreline — represent the community's original character. Many were built as summer cottages between the 1920s-1960s and have been converted (or partially converted) to year-round homes over the decades. These properties carry the highest flood risk and the most complex renovation challenges. On higher ground, the 1960s-1970s suburban expansion built standard New Brunswick housing: split-entries, side-splits, and bungalows on generous lots with well water and septic systems. These homes make up roughly 40% of the stock and are now 45-65 years old — entering the full-systems renovation cycle. The average home in Grand Bay-Westfield is 2,330 sq ft, notably larger than the regional average of 2,005 sq ft, reflecting the rural-suburban character of the lots. Owner-occupancy is approximately 90%, comparable to neighbouring Quispamsis. New development is being actively encouraged through a $5.1 million CMHC Housing Accelerator Fund agreement targeting 160+ new homes in three years and 1,100 over the next decade, with by-law changes promoting denser development — though infrastructure capacity (particularly municipal water and sewer) remains a constraint.
Development History
Grand Bay-Westfield exists on traditional Wolastoqey land — the river the town is built along is the Wolastoq, and the Wolastoqiyik (people of the beautiful and bountiful river) lived here for millennia before European contact. No land treaties were concluded between the Wolastoqiyik and the Crown; the Peace and Friendship Treaties established mutual respect but made no land agreements. French settlement followed Champlain's discovery of the St. John River in 1604, with the area included in the Martignon seigneury extending up the west bank. Loyalist settlers arrived in 1783, including a small group of 31 Black Loyalists, and established the Parish of Westfield within Kings County in 1786. The European and North American Railway Western Extension opened through the area in 1869, eventually becoming part of the Canadian Pacific Railway mainline from Saint John to Montreal. For most of its modern history, Grand Bay-Westfield was 'cottage country' for prominent Saint John families — the steep hills, rocky terrain, and river views made it an escape rather than a working landscape. The municipal structure reflects layers of amalgamation: villages of Pamdenec and Westfield incorporated in 1966; Westfield absorbed Lingley, Sagwa, and Nerepis in 1972; Pamdenec absorbed Grand Bay, Epworth Park, and Ingleside to become Grand Bay in 1973; Grand Bay achieved town status in 1988; Grand Bay and Westfield amalgamated in 1998. The 2023 provincial local governance reform expanded the boundary to include part of the neighbouring Westfield LSD — and after a community vote, the town kept its name over alternatives like Nerepis Valley and Three Rivers. The 2018 and 2019 record floods fundamentally changed the community's relationship with the river that defines it.
Construction & Renovation Guide: Grand Bay-Westfield & West Side
Construction in Grand Bay-Westfield is inseparable from the Saint John River. The back-to-back record floods of 2018 (river reached 5.5 metres — 1.3 metres above flood stage) and 2019 (peaked at 5.53 metres in the Saint John area) caused catastrophic damage to river-adjacent properties, closed roads for weeks, contaminated wells, and triggered a provincial debate about whether any construction should be permitted in flood-prone zones. For contractors, this creates two distinct markets: flood-resilient renovation and new construction on lower-lying riverfront properties, and standard renovation work on the higher-ground suburban homes that make up the majority of the housing stock. The cottage-to-year-round conversion is a signature Grand Bay-Westfield project — transforming seasonal structures into code-compliant permanent homes requires addressing insulation (seasonal cottages often have none), heating systems, foundation adequacy, plumbing (wells and septic), and electrical capacity simultaneously. On higher ground, the 1960s-1970s homes need the same modernization work as equivalent-era homes throughout the Greater Saint John region. The rocky terrain that characterizes much of the community's topography creates excavation challenges for additions and new foundations — blasting or rock breaking is common and adds significant cost.
Common Renovation Projects
- Flood damage repair and resilient rebuilding (mechanical elevation, flood-resistant materials below water lines)
- Cottage-to-year-round conversion (full building envelope, heating, plumbing, electrical upgrade)
- Kitchen and bathroom renovation in 1960s-1970s homes
- Foundation waterproofing and sump pump installation
- Heat pump installation replacing oil furnaces
- Well and septic system upgrades for older properties
- Deck and outdoor living construction on elevated lots with river views
- Rock excavation for additions and new foundations on steep terrain
Typical Renovation Costs in Grand Bay-Westfield & West Side
Estimates based on typical project scope. Actual costs vary by project specifics, material choices, and site conditions.
Unique Construction Challenges
- Flood risk assessment is the mandatory first step for any river-adjacent property — check provincial flood risk mapping at flooding-inondations-geonb.hub.arcgis.com before committing budget to any below-grade or ground-level renovation work
- Rock excavation is common on the steep hillside lots that characterize much of Grand Bay-Westfield — expect to add $15,000-$40,000+ for blasting or hydraulic breaking when digging foundations, septic systems, or utility trenches on rocky terrain
- Well water dependence creates unique renovation constraints — heavy water use during construction (concrete work, pressure washing, dust suppression) can draw down residential wells, and the town's watershed protection program limits development density in some areas
- Cottage-to-year-round conversions often reveal structural inadequacies: posts on concrete piers rather than continuous foundations, no frost protection on footings, single-wall construction without cavity insulation — the conversion is essentially a rebuild within the original footprint
- River-adjacent properties may need to elevate all mechanical and electrical systems above documented 2018/2019 flood levels — furnaces, water heaters, electrical panels, and ductwork that were in basements or ground-level utility rooms must be relocated to upper levels or purpose-built elevated platforms
- Insurance availability and cost for flood-prone properties has changed dramatically since 2018 — some properties near the river have become difficult or impossible to insure at reasonable rates, which affects renovation financing and property values
Foundation Types in Grand Bay-Westfield & West Side
Grand Bay-Westfield's foundation types reflect its split personality between cottage community and modern suburb. The original seasonal cottages along the river — some dating to the 1920s-1940s — were often built on stone piers, concrete block piers, or simple post-on-concrete-pad foundations that were never designed for year-round occupancy. These foundations lack frost protection (footings above the frost line), perimeter insulation, and waterproofing. Converting these to year-round use ideally requires underpinning or replacement with a proper continuous foundation extending below the 4+ foot NB frost depth, though cost often leads to compromise solutions like helical pile supplementation. The 1960s-1970s suburban homes on higher ground have standard concrete block or poured concrete foundations — similar to the rest of the Greater Saint John market. These are reaching 45-65 years old and showing typical age-related deterioration: mortar joint failure in block walls, exterior waterproofing membrane breakdown, and drain tile clogging. The rocky terrain means foundation depths vary — some homes sit almost directly on bedrock while others are in glacial till deposits of varying depth. For new construction, the rock creates both challenges (excavation cost) and advantages (excellent bearing capacity, no settlement concerns).
Common Foundation Issues
- Cottage pier foundations inadequate for year-round occupancy — frost heaving, settlement, and structural inadequacy are common
- Flood damage to foundations in river-adjacent properties — repeated water exposure weakens both concrete block mortar and poured concrete over time
- Well contamination from floodwater infiltrating well casings and aquifers — a recurring issue after both 2018 and 2019 floods
- Rock blasting vibration damage to neighbouring foundations — a risk when new construction or excavation occurs near existing homes on the same rock formation
- Septic system failure due to shallow bedrock limiting drain field capacity — some lots cannot support conventional septic and require engineered systems
Environmental Considerations in Grand Bay-Westfield & West Side
Asbestos
MODERATE RISKProbability in area homes: Present in 1960s-1970s construction; less common in original cottage stock
The 1960s-1970s suburban homes in Grand Bay-Westfield carry typical asbestos risk for that construction era — vermiculite insulation, vinyl floor tiles, drywall compound, and pipe wrap are all potential sources. The original seasonal cottages are less likely to contain asbestos because they were built with simpler materials (wood frame, board sheathing, minimal insulation). However, cottages that were 'winterized' with added insulation during the 1960s-1980s may have had vermiculite or asbestos-containing insulation materials added at that time. Flood-damaged properties present an additional asbestos concern: if flood debris from damaged structures was deposited on a property, it may include asbestos-containing materials from other buildings. Any renovation work should include pre-demolition testing in homes built before 1990, with particular attention to materials added during cottage winterization projects.
Common Asbestos-Containing Materials
- Vermiculite attic insulation (added during cottage winterization)
- 9x9 inch vinyl floor tiles and adhesive
- Pipe insulation on heating system components
- Drywall joint compound in 1960s-1970s construction
- Textured ceiling applications
Radon
HIGH RISKNew Brunswick has one of the highest residential radon rates in Canada, with 1 in 4 homes exceeding Health Canada's 200 Bq/m³ guideline. Grand Bay-Westfield's varied geology — sedimentary bedrock with areas of granite and shale — includes formations with natural uranium content that produces radon gas. The rocky terrain means many homes sit close to bedrock, which can provide more direct radon pathways into foundations through cracks and gaps. Seasonal cottages converted to year-round use are particularly at risk because their original foundations were not designed with radon barriers, and many have dirt floors, stone pier foundations, or unsealed concrete that allows easy gas entry. Every home should be tested with a long-term (90+ day) alpha track detector, and any basement finishing project should include a radon rough-in as a standard precaution. Mitigation (sub-slab depressurization) typically costs $2,500-$4,500.
Soil & Drainage
Grand Bay-Westfield's geology is defined by its steep terrain and proximity to the Saint John River. The higher ground consists of rocky ridges with thin glacial till over sedimentary bedrock — often just a few feet of soil before hitting rock. These areas drain well and provide excellent foundation bearing, but excavation is expensive and septic system installation can be problematic where bedrock is too close to the surface for conventional drain fields. The lower river-adjacent areas have deeper alluvial (river-deposited) soils — silts, sands, and clays laid down by centuries of flooding. These soils are fertile but saturated, with seasonally high water tables that rise dramatically during spring freshet. The 2018 and 2019 floods demonstrated that the alluvial floodplain extends further than many property owners assumed — homes that had never flooded in living memory were inundated when the river exceeded all previous records.
Drainage considerations: Properties on higher ground generally have excellent natural drainage due to the slope and rocky substrate — the challenge is managing runoff velocity rather than standing water. River-adjacent properties face the opposite problem: saturated alluvial soils, high water tables, and periodic flood inundation. For these properties, conventional foundation waterproofing is insufficient — flood-resilient design requires elevating mechanical systems above documented flood levels, using flood-resistant materials below the anticipated water line, installing backflow preventers on all sewer and drain connections, and maintaining battery-backup sump pump systems. The town's reliance on well water for most properties means groundwater quality is directly affected by flood events — after both the 2018 and 2019 floods, the Emergency Operations Centre distributed bottled water to residents whose wells were contaminated.
All environmental assessments should be conducted by qualified professionals before renovation work begins. We coordinate testing and abatement as part of our renovation process.
Property Values & Renovation ROI in Grand Bay-Westfield & West Side
Grand Bay-Westfield's real estate market reflects the flood divide. Homes on higher ground — unaffected by river flooding — command $400,000-$700,000+ and have appreciated steadily, with average listing prices around $500,000 and detached homes averaging $555,000. These properties offer large lots, river views, and a rural feel within 20 minutes of Saint John's employment. The river-adjacent properties present a more complicated picture: while waterfront locations were historically premium, the 2018 and 2019 floods — and the insurance market's response to them — have compressed values for flood-prone properties. Some riverfront homes have become difficult to insure at reasonable rates, and the provincial debate about restricting construction in flood zones has created regulatory uncertainty. Properties that have been flood-proofed (elevated mechanicals, resilient materials, documented mitigation) recover value better than those sold in original condition. The $5.1 million CMHC Housing Accelerator Fund investment targeting 160+ new homes in three years signals strong institutional confidence in the community's growth trajectory.
Market outlook: Moderate appreciation overall, with a growing divergence between flood-safe higher-ground properties (steady demand, rising values) and flood-exposed river-adjacent properties (depressed values, insurance challenges). New HAF-funded development is expected to add density and amenities that benefit existing property values.
Building Permits & Regulations in Grand Bay-Westfield & West Side
Grand Bay-Westfield issues its own building permits through the municipal office at 609 River Valley Drive. All construction requires a permit — including additions, alterations, new builds, relocations, demolitions, and exterior cladding work. Applications require two sets of drawings (site plan, materials list, floor plan, and elevations) that are clear, detailed, and dimensioned. Construction must begin within 6 months of permit issuance, cannot be suspended for more than 1 year, and exterior surfaces intended to be clad must be completed within 6 months. For properties near the Saint John River, the provincial flood risk mapping should be consulted before designing any project — the town's Development Officer can advise on flood zone restrictions. Rezoning applications take 6-8 weeks minimum (3+ months if a municipal plan amendment is required). The Southwest New Brunswick Service Commission handles regional planning coordination. Since January 10, 2024, building inspectors require a pre-pour inspection before any concrete is placed in a slab for buildings with occupancy. Electrical, plumbing, and gas inspections are handled by NB Technical Inspection Services (1-888-659-3222).
Common Permits Required
- Building permit for all structural and envelope modifications
- Development permit for new construction
- WAWA permit for work within 30 metres of a watercourse (significant in this river-adjacent community)
- Demolition permit
- Plumbing permit (NB Technical Inspection Services)
- Electrical permit (NB Technical Inspection Services)
- Rezoning application for non-conforming use changes
- Variance application for setback or coverage deviations
Heritage Considerations
Grand Bay-Westfield has no formally designated heritage conservation areas or individually designated heritage properties under the NB Heritage Conservation Act. However, several of the older river cottages and railway-era structures have historical significance to the community. The original Grand Bay railway station and several Loyalist-era farm structures are of local interest but do not carry formal heritage protection. This means renovation work is not subject to heritage review — an advantage in permitting timelines compared to nearby Saint John.
Zoning Notes
The town has been actively updating its by-laws to promote denser development, partly in response to the CMHC Housing Accelerator Fund commitment to build 160+ homes over three years. Traditionally zoned almost exclusively for single-family residential, the community is now accommodating higher-density proposals — though watershed protection and well water capacity limit how much density some areas can absorb. The zoning by-law governs all use and occupancy of property within the town. Contact the Development Officer at (506) 738-6409 or dtaylor@towngbw.ca before starting any project to confirm current zoning requirements and flood zone restrictions.
Applicable Codes & Standards
- New Brunswick Building Code — Provincial building standards applicable to all renovation work
- NB Technical Inspection Services of New Brunswick — Electrical, gas, and fuel-related work requires permits and licensed technicians
Key Renovation Considerations for Grand Bay-Westfield & West Side
The first step for ANY river-adjacent property renovation is checking the provincial flood risk map — homes in the documented floodplain face restrictions on below-grade work and may require flood-resilient design elements as a condition of the building permit
Cottage-to-year-round conversion is Grand Bay-Westfield's most complex renovation type — plan for a comprehensive approach addressing foundation, insulation, heating, plumbing, electrical, and potentially well/septic simultaneously rather than phased upgrades that may not integrate properly
Rock excavation adds significant cost to any project requiring digging on the hillside lots — get a geotechnical assessment before designing an addition, garage, or septic system to understand what's beneath the surface and budget accordingly ($15,000-$40,000+ for blasting or breaking)
Well water systems on older properties may need upgrading to support renovation scope — a full bathroom addition or in-law suite adds demand that the existing well and pump may not meet, and well yield testing should be done before committing to the design
Insurance is a critical early conversation for flood-zone properties — verify that the planned renovation will be insurable at acceptable rates before starting construction, as some flood-prone properties have experienced significant premium increases or coverage reductions since 2018
Flood-resilient construction for river-adjacent homes means: elevate all mechanical and electrical systems above the 2018 high-water mark (5.5+ metres), use flood-resistant materials (concrete, tile, closed-cell foam) below anticipated water levels, install backflow preventers on sewer connections, and maintain a battery-backup sump pump system
The NB Building Code (NBC 2020 at Tier 2 energy efficiency, effective May 2025) applies to all new construction and major renovations — cottage conversions that substantially alter the building may trigger full code compliance requirements including Tier 2 energy performance
Frequently Asked Questions: Renovations in Grand Bay-Westfield & West Side
Is my Grand Bay-Westfield property in a flood zone?
The provincial government maintains flood risk mapping at flooding-inondations-geonb.hub.arcgis.com that shows documented flood extents. During the 2018 flood, the Saint John River reached 5.5 metres (flood stage is 4.2 metres), and the 2019 flood peaked at 5.53 metres in the Saint John area — both shattering the previous 1973 record of 5.31 metres. Properties in Brandy Point, Mill Cove, parts of Martinon and Ketepec, and along the low-lying Nerepis Road area were among the worst affected. Even properties that never flooded before 2018 were inundated — the record-breaking levels exceeded all historical assumptions. Before purchasing or renovating any property near the river, check the flood maps and consult with the town's Development Officer at (506) 738-6409. Your insurance broker should also be consulted early, as flood history significantly affects coverage availability and premiums.
How much does a cottage-to-year-round conversion cost in Grand Bay-Westfield?
A comprehensive cottage-to-year-round conversion in Grand Bay-Westfield typically costs $80,000-$180,000 depending on the cottage's starting condition and size. The major cost components are: foundation upgrade or underpinning to extend below frost depth ($15,000-$40,000), full building envelope insulation and vapour barrier ($15,000-$30,000), heating system installation — typically a heat pump with backup ($8,000-$18,000), plumbing system including well pump upgrade and potential septic replacement ($10,000-$35,000), electrical service upgrade to 200-amp and full rewiring ($8,000-$15,000), kitchen and bathroom installation ($25,000-$50,000), and windows and exterior finishing ($10,000-$25,000). For river-adjacent cottages, add $15,000-$40,000 for flood resilience measures. The scope often makes this more of a rebuild than a renovation — the original cottage structure provides the footprint and perhaps some framing, but nearly every system gets replaced.
What are the building permit requirements in Grand Bay-Westfield?
All construction in Grand Bay-Westfield requires a permit — including additions, renovations, new builds, and even exterior cladding changes. Apply at the municipal office at 609 River Valley Drive or contact the Development Officer at (506) 738-6409 (dtaylor@towngbw.ca). You'll need two sets of drawings including a site plan, materials list, floor plan, and elevations. Important timelines: construction must start within 6 months of permit issuance, cannot be suspended for more than 1 year, and exterior surfaces must be clad within 6 months. Since January 2024, a pre-pour inspection is required before placing concrete in any occupied-building slab. For river-adjacent properties, the Development Officer will advise on flood zone restrictions. Electrical and plumbing permits are separate through NB Technical Inspection Services (1-888-659-3222).
Does rock affect construction costs in Grand Bay-Westfield?
Yes — significantly. Grand Bay-Westfield's characteristic steep terrain means bedrock is often close to the surface, particularly on the hillside lots above the river. When building a foundation, digging for a septic system, or excavating for utility trenches, hitting rock adds substantial cost. Blasting or hydraulic rock breaking can add $15,000-$40,000+ to a foundation project depending on the volume of rock to be removed. On the positive side, building on rock provides excellent bearing capacity (no settlement concerns) and superior drainage on sloped sites. The key is getting a geotechnical assessment before finalizing any design that requires excavation — knowing what's below the surface before committing to a plan prevents costly surprises. Some lots have enough soil depth for conventional excavation while neighbouring lots are solid rock at 2 feet — there's no reliable way to predict without testing.
What is the Housing Accelerator Fund doing for Grand Bay-Westfield?
Grand Bay-Westfield received over $1 million through the CMHC Housing Accelerator Fund (HAF) to support five local initiatives: promoting increased density, providing incentives for affordable housing, repurposing town-owned land for development, reviewing infrastructure planning, and updating by-laws to enable faster construction. Combined with funding for neighbouring communities, the HAF commitment targets 160+ new homes over three years and 1,100+ over the next decade. For homeowners, this means zoning changes are coming that may allow secondary suites, duplexes, and higher-density development on properties that were previously restricted to single-family use. For contractors, it means a pipeline of new construction work as the town evolves from a purely single-family community into a more diverse housing market.
About Grand Bay-Westfield & West Side
Grand Bay-Westfield is a community defined by its river — and humbled by it. The Wolastoq (Saint John River) gives the town its beauty, its identity, and its most serious construction challenge. The back-to-back floods of 2018 and 2019 were not just natural disasters — they were a permanent recalibration of what 'building near the river' means. Properties that had never flooded in living memory went underwater. Roads that communities depended on were closed for weeks. Wells were contaminated. And a provincial conversation began about whether building in flood zones should be permitted at all. For contractors working in Grand Bay-Westfield, this context shapes every project. River-adjacent work requires a different mindset — flood resilience is not an upgrade, it is the baseline. Mechanical systems go on upper floors, not in basements. Materials below potential water lines must survive submersion. Backflow preventers and battery-backup sumps are standard, not optional. But Grand Bay-Westfield is not only a flood story. The higher ground — the steep, rocky terrain that drew cottage builders a century ago — offers some of the most beautiful residential settings in the Greater Saint John region. Homes perched on hillsides with river views, mature forest lots, and the quiet that comes from being just far enough from the city — these properties represent a different kind of opportunity entirely. The cottage-to-year-round conversion market bridges both worlds: seasonal structures on stunning waterfront sites that can become permanent homes with the right investment. The $5.1 million Housing Accelerator Fund commitment signals that Grand Bay-Westfield's next chapter is about growth and density — a significant shift for a community that has been almost exclusively single-family homes. Contractors who understand both the flood constraints and the development opportunities will find this a rewarding market.
