is doing an excellent job

For the STVs, different immigration offices seem to be having different requirements. The strictest immigration office for the extension of stay based on STV is Bangkok immigration. I am attaching an e-mail from Bangkok Immigration explaining what their requirements are for a 90 day extension of stay based on STV.

Regarding health insurance: You *WILL* need the same insurance policy that you used to get the STV. There are lots of reports of rejections for not meeting the health insurance requirements.

For housing: Bangkok Immigration require one of the following:

- Pre-payment for a hotel WITH the Owner's Tax ID number.

- A copy of your rental agreement

- A copy of your condo ownership book.

VERY few people have this visa. CONTACT your immigration office.

I'm going to leave comments open for now, just in case there's anyone in Chiang Mai who got this extension of stay recently.

Have you asked your Thai immigration office for their list of requirements for the STV extension?

Just a reminder, the OP is asking about Chiang Mai. What happens at other Immigration offices may not matter.
