Check a street
Start typing a street name — Savannah Hwy, Bees Ferry Rd, Avondale Ave, Ashley Hall Rd, and about 40 more are in the table.
What's in the table
About 40 of West Ashley's major streets and neighborhood interiors, each with a ZIP code, a City-of-Charleston vs. unincorporated read, a tax note, and links. This is a starting point, not a legal determination: some streets run through both the city and the county (Carolina Bay straddles the boundary), and annexations move lines over time. For any address you're serious about, confirm the tax district on the Charleston County Auditor site or the tax bill, and the flood zone on FEMA's Map Service Center — or ask me and I'll pull it.
Common questions
How do I find the exact tax district for a specific address?
Use the Charleston County Auditor's property records or the property's tax bill — the district (City of Charleston, St. Andrew's PSD, a fire district) is printed on it. This street check tells you the likely district so you know what to verify.
Why does it matter whether a street is inside the City of Charleston?
The millage is different: in 2025 the city levied 298.1 mills, while unincorporated areas fell under districts like the St. Andrew's PSD (314.9) or the W. St. Andrew's Fire District (240.2). City and county stormwater fees differ too ($132/yr vs $72/yr). See the true-cost ledger for a side-by-side.
How do I check the flood zone for an address?
Start with the site's flood zone lookup, then confirm on FEMA's Map Service Center. Flood insurance quotes are priced per address — get one before you offer.
