Building Permit (unincorporated Mobile County): Residential (1-2 family) new construction/additions (conditioned space): $25 + $0.62/sq ft, $225 minimum — bundles building, electrical, mechanical, plumbing, roof and misc. permits.

What does a contractor or trade need in Mobile County Al that other businesses do not?

3 of the 3 permits particular to a contractor or trade here apply to no other business type we cover in Mobile County Al: Building Permit (unincorporated Mobile County), General Contractor License and Residential Home Builder License.

Building Permit (unincorporated Mobile County)

A contractor building, demolishing, altering or repairing a structure in unincorporated Mobile County needs a building permit from the county's Inspection Services Department (1110 Schillinger Road N, Mobile, AL 36608; 251-574-3507). This applies only in the unincorporated area: every incorporated city in Mobile County runs its own building department instead. The county's own Development and Zoning page states that 'There is no zoning in the unincorporated areas of Mobile County' and that the county will confirm this officially for a specific parcel on request. Fees under the Exhibit A schedule (effective July 1, 2026) run $25 plus $0.62/sq ft ($225 minimum) for a new 1-2 family residence, 0.6% of contract cost ($200 minimum) for new commercial construction, and 0.6% of contract cost ($100 minimum, plus a flat $100 plan review) for a commercial repair or alteration; a new dwelling is valued at not less than $125/sq ft for permitting purposes. Electrical work in unincorporated Mobile County must be performed by a certified person or business, per the License Commission's own New Business resource page. Separately, contractor licensing itself is a state matter: the Alabama Licensing Board for General Contractors requires state licensure for commercial/public-works contracting once a project's cost reaches $100,000 (raised from $50,000 by Act 2024-277, effective October 1, 2024), and the county publishes no additional Mobile-County-specific contractor licensing board or exam beyond that state threshold and this building-permit process.

General Contractor License

The threshold moved on 1 October 2024 and a lot of published material has not caught up: the license is required where the cost of the undertaking is $100,000 or more, raised from $50,000, and the same figure applies to public and private work and to subcontractors. Swimming pools have their own much lower trigger at $5,000. Two official documents still say $50,000 — the board's own rule 230-X-1-.09 and its 2022 subcontractor instructions — and the statute controls. A subcontractor pays exactly half of everything: $150 new and $100 to renew against $300 and $200. Renewing more than ninety days late costs another $50. Your bid limit is set from your financial statement at ten times the lesser of net worth or working capital, which sorts licensees into classes from $100,000 up to unlimited. Residential work belongs to the Home Builders board instead, and the privilege license banded by contract value is owed on top.

Residential Home Builder License

Residential building is a separate board with a much lower trigger than the general contractor one: $10,000 for building work and just $2,500 for residential roofing. Two hundred and fifty dollars a year covers the $235 license and the $15 homeowners' recovery fund contribution, with $100 more for a new applicant's first year; a roofing-only license is $150 with no recovery fund fee. The boundary between the two boards is jurisdictional rather than financial — the general contractor statute exempts residences and private dwellings, and this board's remit stops at structures no more than three floors high with no more than four residential units, above which it reverts. There is a grandfathering quirk worth checking: general contractor license numbers up to 18907, issued before this board existed in 1992, may still do residential work, while 18908 and above may not. The three tiers turn on scope, not money — a single trade not affecting structural integrity is limited, anything structural or spanning trades is unlimited, and roofing has its own class with a $10,000 bond and no examination.

The other 1 local permit in the tables apply to every type of business in Mobile County Al, AL; what each one involves is set out on the Mobile County Al permits page. The 5 state-level registrations apply to every type of business across AL and are covered on the AL state page.
