Adding a ADU with the town

[Seth Alexanderowicz]

Hey so I recently closed on a property that has a in-law appt on it. Was doing my homework and it meets all the qualifications and have called the town to make sure I was able to do it and they said yes. Next step is to fill out a application/ building permit and suMmit floor plans to try to get it registered by the town to legally be able to collect rents from it. (Guessing previous owners only had family in there so they never had to register it.) just curious if anyone else has xp in this and how long the process takes please and thanks.
