Why San Francisco Takes Healthy Cleaning So Seriously

Ask someone from another state what they think of San Francisco and "environmentally obsessed" will probably come up. It's a bit of a stereotype. It's also mostly true, and when it comes to cleaning products, the city has a real track record to back it up.

The city wrote caution into law

In 2003, San Francisco adopted the Precautionary Principle as part of its Environment Code. The basic idea: when there's reasonable concern that something could harm people or the environment, the city shouldn't wait for complete proof before choosing a safer option.

That thinking shaped how San Francisco buys products for its own buildings, including cleaning supplies. City departments are steered toward safer alternatives, and the Department of the Environment has spent years helping businesses do the same.

Green business is a local habit

San Francisco runs a Green Business Program that helps local companies cut waste, save energy, and use safer products. Plenty of restaurants, offices, and shops around the city have gone through it. The East Bay has its own versions too.

The result is a culture where people expect businesses to think about this stuff. If a cafe still uses foam cups or an office uses harsh cleaners, someone will ask about it.

California made cleaning ingredients public

For a long time, cleaning companies didn't have to tell you much about what was in their products. That changed with California's Cleaning Product Right to Know Act, signed in 2017. It requires manufacturers to list intentionally added ingredients online and on product labels, including many fragrance allergens that used to hide behind the word "fragrance."

It was the first law of its kind in the country. Because California is such a big market, it pushed a lot of brands to clean up their labels everywhere, not just here.

Bay Area homes give people a personal reason to care

Policy is one part of it. Daily life is the other.

A lot of people here live in older, smaller homes. Victorians and Edwardians split into flats, garden units, apartments built decades before modern ventilation. Add the fog that keeps western neighborhood windows shut and the wildfire smoke that's sealed everyone indoors more than once, and you get a lot of people thinking hard about what's in the air at home.

The Bay Area also has a lot of young families, a lot of dogs, and a lot of people with allergies or asthma who've learned to read labels. For them, "what does the cleaner use?" isn't a fringe question. It's one of the first things they ask.

What healthy cleaning looks like here now

For most Bay Area households, it's less about perfection and more about better defaults:

• Products with readable ingredient lists instead of mystery formulas.
• Less synthetic fragrance, fewer aerosols, no scented plug-ins.
• Skipping chlorine bleach for everyday cleaning and saving disinfectants for when they're actually needed.
• Reusable microfiber instead of rolls of paper towels.
• Cleaning services that bring their own eco-friendly supplies by default, not as an upsell.

Where Sano fits in

We started Sano in the Bay Area, so this way of thinking was baked in from the beginning. Every clean uses products from Branch Basics, Koala Eco, and Seventh Generation. It's the same kit on every job, whether it's a studio in the Tenderloin or a family home in Lafayette. You can read why we chose those three brands.

San Francisco set the bar a long time ago. We think a house cleaning should meet it.
