San Francisco / North Fair Oaks
North Fair Oaks has 13,100 residents (give or take 1,412) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US0651840, checked 2026-10-19), about 10,953 people per square mile.
North Fair Oaks is about 49 miles from the Census center point for San Francisco in a straight line and covers 1.196 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
At 10,953 people per square mile, North Fair Oaks is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
Of the 3,856 occupied homes in North Fair Oaks, 57% heat with natural gas, 0% with heating oil, 34% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0651840, checked 2026-10-19).
Gas heats 57% of North Fair Oaks against electricity at 34%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
North Fair Oaks has about the San Mateo County oil share of 0% and 2 points more electric heat than the county's 32% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US06081, checked 2026-10-19).
North Fair Oaks has 4,114 housing units, 14% built before 1940 and 75% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0651840, checked 2026-10-19).
North Fair Oaks has 5 points more pre-1940 homes than San Mateo County as a whole (9%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US06081, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median North Fair Oaks home was built in 1958 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US0651840, checked 2026-10-19) and the median home has 4.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US0651840, checked 2026-10-19).
58% of North Fair Oaks homes are single-family detached, 10% are in two- to four-unit buildings and 18% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0651840, checked 2026-10-19).
52% of North Fair Oaks homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0651840, checked 2026-10-19), so beside the 58% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
North Fair Oaks has 11 points fewer five-plus-unit buildings than the county's 29% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US06081, checked 2026-10-19).
52% of North Fair Oaks homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US0651840, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
75% of North Fair Oaks homes were built before 1980 and only 13% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0651840, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for North Fair Oaks on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in North Fair Oaks is $104,884 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US0651840, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 29F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), San Mateo County row, 99% heating, PDF pages 11 to 13 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 29F figure is the San Mateo County cold-day number a North Fair Oaks heat pump is sized against, so ask the installer to show the system's heating output at 29F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 57% of North Fair Oaks on gas and 34% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median North Fair Oaks home has 4.3 rooms and was built around 1958, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
