What Affects Your Timeline

Project timelines in West Boylston vary based on ADU type. Conversions are fastest (4-6 months total) since you're reusing existing structure. Detached ADUs take longest (8-14 months) due to foundation work and full construction. Weather, contractor availability, and plan revision requests from the building department also affect your schedule.
