Mobile County runs from pine woods on the Mississippi line to the barrier island at the mouth of Mobile Bay. The Mobile County interactive tax map covers old city lots, suburbs and bayou frontage alike.
The Revenue Commission’s tax map
In Mobile County, a single Revenue Commission handles both assessment and collection, so its interactive tax map is the main public parcel viewer. The map is hosted by BIS Consultants. Its disclaimer says the product is informational, not for legal, engineering or survey use, and shows only approximate relative locations of boundaries. It adds that ownership data is always being updated and recommends disabling pop-up blockers and clearing the cache.
Click I Agree and the map opens with a single search box. Links let you email the mapping vendor or the Revenue Commission with questions. The map is linked on the Mobile County line of our Alabama directory, and the county is at the state’s southwest corner on our national map.
Parcel numbers and PPINs
Alabama counties typically assign each parcel a long parcel number keyed to township and section, and many also use a shorter personal property identification number, or PPIN, for the tax account. Search by either, or by owner or address. Tips:
- Older neighborhoods in Mobile have many lots owned by estates, so try the family name without first names.
- When an address will not match, pan to the parcel and click it.
- Current-use valuation for farm and timber land shows on the tax record, not the map.
How to find property lines in Mobile County
City lots follow old plats, while much of the county uses section, township and range descriptions.
- Read the legal description from the tax record.
- Get the deed and plat from the Mobile County Probate Court, which records real estate documents in Alabama.
- Locate corner pins; in sandy soil near the coast, they may be buried or shifted.
- Hire an Alabama licensed professional land surveyor for fences, piers or disputes.
Colonial grants and old Mobile
Mobile was founded by the French and later held by the British and Spanish, and some old tracts along the bay and rivers trace back to colonial grants. Those parcels have irregular shapes that do not match the section grid. Downtown lots can be narrow and deep, with shared walls and alleys that matter for title.
Bay, bayous and hurricane risk
Dauphin Island, Bayou La Batre, Coden and the western shore of Mobile Bay face storm surge, and much of this land is in high-risk flood zones. Wind and flood insurance costs vary sharply by location and elevation. Check the flood layer and our guide to reading flood zones, and ask for an elevation certificate.
West Mobile and the growth areas
West Mobile, Semmes, Theodore and Grand Bay have seen most new housing, while Saraland, Satsuma and Creola lie north along the river and Interstate 65. Each city handles zoning inside its limits; much of the unincorporated county has limited zoning, so confirm what applies before buying.
Mobile County plat book
We could not confirm a current printed atlas. Plats recorded at the Probate Court are official, and the Revenue Commission map shows ownership for free.
Timberland and hunting access
Northern and western Mobile County holds pine plantations and hunting clubs around Citronelle, Wilmer and Chunchula. Click a tract to see acreage and owner, which helps when approaching a landowner or timber company about access. Public hunting follows Alabama Department of Conservation and Natural Resources rules.
The port, Brookley and industrial land
The Port of Mobile is one of the busiest on the Gulf, and the riverfront north and south of downtown is lined with terminals, shipyards and industry. Airbus builds commercial jets at the Mobile Aeroplex at Brookley, and suppliers have followed. Industrial zoning and heavy truck traffic affect nearby homes, so check the zoning layer and look around at different times of day before buying near these areas.
Downtown Mobile has historic districts, including the Oakleigh Garden and De Tonti Square areas, where exterior changes typically need review by the city’s historic commission. A cottage in one of those neighborhoods can be charming, but replacing windows or adding a porch may involve extra approvals.
Is the Mobile County GIS map accurate?
The disclaimer says boundaries are approximate and not suitable for survey use. City lots generally match imagery, while rural timber tracts can be off. Get a survey before building near a line; see how tax maps compare with surveys.
Tax map not opening?
The Revenue Commission suggests turning off pop-up blockers and clearing your cache. If the search box stays gray, reload or switch browsers. Across the bay, see our Baldwin County guide, or browse the Alabama county GIS hub.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey — especially for fences, setbacks, or boundary disputes.
