East Kootenay, Electoral Area B

In Area B, a zone limited to detached houses must allow at least one secondary suite or detached accessory home (a garden suite or carriage house) next to a house. A floor of 3 or 4 homes applies on rural land only inside an urban containment boundary drawn in a regional growth strategy, and most rural land is outside one. None of it applies on land in an Islands Trust local trust area or under a rural land use bylaw, and in the Agricultural Land Reserve the Commission's limits come first. How many homes you can build on a lot.

The Province's principal residence requirement doesn't apply in Area B (list in force from June 1, 2026), so the provincial rule doesn't limit short-term rentals to the host's home. Local bylaws, including the zone's own rules, can be stricter. Hosts anywhere in BC register each unit with the provincial registry. Short-term rental rules in BC.

Reports for rural lots in Area B name the zone from the Regional District of East Kootenay's zoning map, where 3 bylaws apply.

• South Country Zoning & Floodplain Management Bylaw No. 2320, 2011Covers 23% of the area. 17 zones explained, from the bylaw as amended to February 13, 2026, checked October 29, 2026.
• Jaffray, Tie Lake, Rosen Lake Land Use and Floodplain Management Bylaw No. 1414, 1999Covers 1% of the area. 10 zones explained, from the bylaw as amended to May 8, 2026, checked October 29, 2026.
• SweetWater Zoning & Floodplain Management Bylaw No. 2127, 2009Covers under 1% of the area. 10 zones explained, from the bylaw as amended to June 12, 2026, checked October 29, 2026.

Shares of the area's land and water, worked out from the Regional District of East Kootenay's zoning map (Open Government Licence – Regional District of East Kootenay); a bylaw is listed where at least 20 ha and 1% of it lies here. Lots inside a municipality follow its own bylaw. Confirm with the RDEK's planning department before you buy or build.

Check one lot: look up its address for its zone and the share of the lot in each.

The federal boundaries put one reserve, Tobacco Plains 2 (Yaqit ?a·knuqli'it First Nation), in or beside Area B. On reserve land the First Nation decides land use, not the local zoning bylaw; a report says when a lot is on reserve land or within 500 m of it. Reserve land in BC, by place.

The Regional District of East Kootenay's building inspection covers all of Area B (Building Regulation Bylaw No. 3254, 2023): building, adding on, moving or demolishing a building needs a building permit, and the work is inspected. Our reading of the Regional District of East Kootenay's own page, checked 2026-10-07. Do you need a building permit on rural land?

The Province maps 2 designated community watersheds, Reserve Community Watershed and Miller Creek Community Watershed, over less than 1% of Area B: land draining to a licensed drinking-water intake, where logging and roads on Crown land must protect the supply. A report says whether a lot lies in one and whose water it is. Community watersheds in BC, by place.

Check one lot: is it in the ALR? · is the soil good for farming? · is it in a community watershed?

The Province's monitoring records hold groundwater samples from 3 wells in Area B, 2002 to 2017, among them 1 of the Province's observation wells. No well's median passed Health Canada's limits for arsenic, fluoride, manganese, uranium, nitrate or lead. A report names the nearest sampled wells within 10 km of a lot. A neighbouring well isn't your water: test your own. What BC's well water tests for, by place.

Mapped aquifers

An aquifer is listed for each place that holds at least a twentieth of it, so a sliver of one at the edge can be left out. Wells and productivity are for the whole aquifer, which can reach well beyond Area B. The province maps aquifers mostly in settled valleys, so a lot outside every outline can still have groundwater.

Sampled lakes

4 sampled lakes lie in Area B (one only partly), largest first.

2. 2Suzanne Lake39.8 hatoo few readings to judge
3. 3North Star Lake21.1 hatoo few readings to judge
4. 4Unnamed lake in the Bull River watershed8.9 hatoo few readings to judge

A lake is listed for each place that holds at least a twentieth of it or 100 ha of it. Clarity is the median summer Secchi depth; the nutrient class is our reading of Carlson's index from phosphorus or chlorophyll, not a provincial rating. Either is given only for a lake with at least 10 summer readings from open water, spread over at least 3 different years, since 2012. Most lakes have never been sampled, so a lake missing here may simply have no record. Every sampled lake in BC.

Normals for 1981-2010 at the Wardner Kootenay Hatchery station, about 16 km from Jaffray (of the communities here with a station within 30 km, the one with the most addresses); ECCC has no fuller 1991-2020 set for it. Its normals don't include the frost-free period, days with snow on the ground or degree days, so those are left out. * Based on at least 20 or 15 of the 30 years, short of the World Meteorological Organization's standard: treat as a rougher guide. The records are single days measured at the station: the most rain, snow and wind it saw in its record up to 2010 (ECCC's 1981-2010 sets give records over the station's whole history, so some dates are older than 1981). Each is one event, not what to expect in a year, and the lot can get more or less than the station. Elevation matters a lot in BC: a hillside lot can be much colder and snowier than the station. We don't set this station's figures against other places: it's more than 15 km from the place.

Plant hardiness zone: most homes here are in zone 5b (86%); 14% are in 5a, on Natural Resources Canada's 2025 map. Higher numbers are milder winters. What the zones mean.

Solar panels: a south-facing panel tilted at the latitude would make about 1,120 kWh a year for each kW of panels at Jaffray, about 48 of it in December (estimated from Natural Resources Canada's 1998-2022 sunshine map). An open sky is assumed: the hills, trees and buildings around a lot cut it, and a report sets the lot's own skyline beside it. What solar panels would make in BC.

By the 2050s (2041-2070) at Jaffray, climate models project about 25 more days over 30 °C a year, a longest frost-free run about 30 days longer and about 12 percentage points less of winter's precipitation falling as snow, each against the same models' 1971-2000 (model projections under SSP2-4.5, a middle path for emissions). The models work on a grid of about 9 by 6 km, which averages valley floors with the slopes around them, so their own figures can sit well off a station's normals and aren't comparable with them. Their own figures there: about 39 days over 30 °C a year in 2041-2070 (range 32 to 59 across the models), against about 14 days in 1971-2000; a longest frost-free run of about 150 days (range 140 to 180), against about 120; and about 70% of winter's precipitation falling as snow (range 60% to 72%), against about 82%. The ranges run from the 10th to the 90th percentile of the models' 2041-2070 figures. The 2050s across BC.

Light at night within 1 km of Jaffray: faint, as around Wells or Lytton (our reading), and darker than about 87% of BC's homes (2024 satellite record). A lot away from the centre can be much darker. How dark are BC's nights?

Lightning: around Jaffray, a cloud-to-ground flash within 10 km on about 14 days a year and 0.34 flashes per km² a year, more than at 3 in 4 BC homes (the Canadian Lightning Detection Network, 1998-2025 average, on a grid of about 11 by 7 km).

The BC Energy Regulator maps about 61 km of active oil and gas pipeline in Area B, permitted to 2 companies: FortisBC Energy Inc. and Foothills Pipe Lines (South B.C.) Ltd. About 5.4 km more is on recent permits it lists as new; under a kilometre is abandoned or deactivated, often still in the ground. A report lists any pipeline within 200 m of a lot, and flags one within 30 m, where digging needs the permit holder's agreement. Pipelines in BC, by place.

The Province lists 14 active waste discharge authorizations in Area B; the commonest kinds: sewage treatment or discharge site (5), wood treatment plant (3) and sawmill or other primary wood processing (2). Of these, 6 may discharge to air, 7 effluent to water or land and 2 refuse to land. A report lists any within 2 km of a lot, and flags one whose point is on it. Permitted discharges in BC, by place.

The Province maps no open gravel pit or quarry in Area B, but 2 open mineral exploration permit areas. A report lists the permits within 2 km of a lot, names an open pit or quarry within 500 m and flags one whose permit area takes in the lot. Gravel pits and mine permits in BC, by place.

On ParcelMap BC, the land in Area B is 9% private, 45% Crown land with a parcel drawn (32% with no title), 2% federal; no parcel is mapped over 44%, likely most of it untitled Crown land, with lakes and road allowances. A report says who owns the land along a lot's line. Crown land next to a property, and every place's land by owner.

The Ministry of Forests maps 35 active Crown range tenures (35 grazing) reaching into Area B, over 76% of its area, licensed for about 12,956 animal unit months of grazing a year in all. Outside a pound district, keeping livestock off a lot is the owner's fence to build. A report lists any tenure within 1 km of a lot. Open range and grazing in BC, by place.

The Province maps 23 registered traplines over 88% of the area and 6 guide outfitter territories over 81% in Area B. The maps are drawn over titled land too, but traplines are registered on Crown land: on titled land, anyone but the owner or occupier needs their written permission to trap. A report says whether either takes in a lot. Traplines and guiding territories in BC, by place.

Area B lies in wildlife management units 4-2 (40%), 4-3 (40%), 4-22 (19%): the Hunting and Trapping Regulations Synopsis sets seasons and closed areas by unit. Hunting and shooting on your own property.

BC Parks maps 2 parks and protected areas (Elko Park, a provincial park; and Kikomun Creek Park, a provincial park) reaching into Area B, over less than 1% of its land.
