Internal combustion blowers and line trimmers are legal here. All my neighbors have switched to electric blowers. The lawn guy also runs a fully electric setup with mowers, trimmers and blowers.

It’s not legislated. The battery gear is just simpler and more reliable. And the fact it’s quieter is a bonus.

Electric trimming apparatus exist. On a 14 gauge extension cord you can safely have things on an ordinary 120 volt circuit with a 1500 watt motor, so there is more than enough power. Noisy, yes, but not as polluting as a small two-stroke engine and not nearly as loud.

It's a historic city with small lots which probably makes it a lot easier, and I think the ban only covers certain areas. I couldn't tell you all the details because I only moved here recently, but they banned selling a few years before banning using them. I do see some commercial landscapers still using those wide ones that you sit on like a throne and control with joysticks or something, and I'm sure a lot of people without permission still use gas powered but not on my street.

It will have to work. https://www.consumerreports.org/emissions/california-ban-on-...

Washington, DC, has outlawed gas-powered leaf blowers, and they seem to have mostly disappeared. Honestly I don't know about trimmers.

It might just not work. I lived in a place where gas powered landscaping equipment was illegal and it was widely ignored.
