Mobile, AL Property Maintenance: Vacant Lot Maintenance (2026)

Section 52-52, the definitions section for Chapter 52's Article III weed and grass ordinance, defines 'vacant lot' broadly: any area of land with no structure on it, or with an unoccupied structure, whether that structure was business or residential, and the definition expressly pulls in adjoining or included rights-of-way, easements, ditches and alleyways as part of the lot. The same section defines 'public nuisance' as any growth of weeds, scrub bushes or grass exceeding community standards, normally 10 inches in height, and/or nonorganic debris that presents a fire, health or safety hazard or otherwise endangers surrounding areas, the exact same standard that applies to occupied property under Section 52-53.

That means an empty parcel doesn't get a pass just because no one lives there; the duty to cut and clear runs to 'any owner or occupant,' and a vacant lot's owner is on the hook the same way an occupied homeowner is. The Property Maintenance Code backs this up separately: Section 301.3 requires that 'vacant structures and premises thereof or vacant land shall be maintained in a clean, safe, secure and sanitary condition ... so as not to cause a blighting problem or adversely affect the public health or safety,' folding vacant land maintenance into the same code that governs occupied buildings.

A vacant lot over five contiguous acres can qualify for the farm exemption under Section 52-55, but only if the owner still maintains the required 50-foot buffer along abutting lot lines and roads; heavily wooded, natural-state parcels are excluded outright.
