Homes and buildings in Senneville
In the 2021 census, 310 of Senneville’s 350 occupied dwellings are single-detached houses, and 81% of households own their home. About 210 dwellings were built in 1960 or earlier, including 60 from 1920 or before, and only 10 since 2016 (counts are rounded to the nearest 5). Houses this old may have ductwork sized for earlier equipment, so we check airflow before recommending a replacement or a heat pump.

Before an outdoor unit goes in
Senneville’s zoning by-law 448 allows heat pumps in side and rear yards, not the front yard. Keep the unit at least 2 m from the lot line if it is screened, otherwise 3 m, and hide a side-yard unit from the street with opaque landscaping. The village requires a certificate of authorization. Check the permit with the municipality before installation; we size and place the unit to meet it.
