The county is genuinely mixed: 1,690 of 2,830 classified parcels are on septic and the rest are sewered. Which side of that line a Otis address falls on is worth establishing before anything else. The county publishes a records portal, but reaching the documents needs an account or a login, so budget for that step rather than expecting an open search.
