Soapy wash water flowing to the street storm drain is an illicit discharge under Title 24. Wash on grass or gravel that infiltrates on-site, or use a commercial car wash that recycles wastewater.

Yes, if the site disturbs 1 acre or more (including smaller sites part of a larger common plan). Apply for the NDEP Construction Stormwater General Permit and prepare a SWPPP before ground disturbance.
