Just wanted to share that I successfully got the Residential Certificate today at the Chaeng Wattana Immigration Office. I have a DTV. I brought them my TM-30 that my landlord gave me a week after I moved in; a copy of the info page of my passport; a copy of my visa and entry stamp, and that’s it. I checked the boxes for wanting to get a drivers license and buying a car and so they charged 400 baht which I paid right there in cash. They gave me a little slip as receipt and said it would reach me in seven days by post. Also, I’ve only been here for 42 days so the 90 day requirement/report was not necessary there. Hope this helps
