A heater is required by the department of building & safety and by the housing department. You could probably do without but during winter it gets as low as 40 to 45 degrees Fahrenheit.
The cold months are between the middle of November to the end of April.
Typical heaters are Gas Furnaces, they can be wall mounted or centrally located and the heat distributed but ducts in the ceiling of the houses. Typically a 35,000 BTU would suffice to cover up to 1,500 Sq Ft. (you should verify this). Depending of what part of the world you are from you may think this weather as extremeâ€¦ if you are close to the equator line, you are probably used to milder temperatures. However for being a northern hemisphere location, Los Angeles has relatively AWESOME weather (especially close to the beach). It does not get super-super-hot and humidâ€¦ it does not freeze and get icy roads or anything like thatâ€¦ but you are a couple of hours drive from snow, desert, mountainsâ€¦ where you can experience and sorts of climates.
Hope this helpsâ€¦ if you find my answer useful, give it a Thumbs Up, or select it as the best answer!
