Overview

Looking for a one-of-a-kind property in the heart of St. Augustine? This original 1885 cottage with an accessory dwelling sits on a commercially zoned lot just a 15-minute walk to the Historic District or a quick drive to the beaches. Once used as crew quarters for the Florida East Coast Railway, the home has been thoughtfully restored with hardwood floors, stained-glass transoms, and modern updates.

A connecting door between the two units offers flexibility for multiple living arrangements. The accessory dwelling features a full bath, laundry center, and kitchenette, making it an ideal mother-in-law suite or private rental. Currently operated as a five star rated short-term rental, this property is both a piece of history and an income-producing opportunity in a prime location.
