How long does it take to permit an ADU on Summerville in 2026?

ADU permit timelines in Summerville depend on the project's scope and which of the three counties the specific parcel sits in, since Dorchester, Berkeley and Charleston counties each run their own building and zoning review process. A complete, code-compliant application typically moves faster than one needing a variance or special exception from the local zoning board. The relevant county or town building department can give the most current timeline estimate based on their present workload.
