Alabama’s state bid laws require government entities to award most contracts through sealed competitive bidding once the price crosses a set dollar threshold. For local governments buying goods, services, or labor, that threshold is $30,000. For public works projects like construction and road building, it climbs to $100,000. State agencies follow a separate article with its own procedures. Contracts awarded in violation of these rules are void, and the officials responsible can be charged with a Class C felony.
Which Entities the Bid Laws Cover
Alabama splits its competitive bidding rules across three sets of statutes, and the right one depends on who is buying and what they are buying.
- Local governments follow Article 3 of Chapter 16 (§§ 41-16-50 through 41-16-63). That includes county commissions, municipal governing bodies, independent school district boards, and the governing boards of local instrumentalities such as waterworks, sewer, and gas boards. The Alabama Fire College is also covered.1Alabama Legislature. Alabama Code 41-16-50 – Contracts for Which Competitive Bidding Required
- State agencies, boards, bureaus, commissions, and authorities follow Article 2 (§§ 41-16-20 through 41-16-33).
- Public works, meaning construction, repair, renovation, or maintenance of public buildings, roads, bridges, sewers, and waterworks paid for with public funds, is governed by Title 39 rather than the general bid law.2Alabama Legislature. Alabama Code 39-2-2 – Advertisement for and Opening of Bids
A city buying office furniture works under Article 3. That same city building a new fire station works under Title 39. Each track has its own threshold, its own advertising rules, and its own procedures.
The $30,000 Threshold for Local Purchases
Under Article 3, any expenditure of $30,000 or more for labor, services, work, or the purchase of materials, equipment, supplies, or other personal property must go through sealed competitive bidding.1Alabama Legislature. Alabama Code 41-16-50 – Contracts for Which Competitive Bidding Required The rule applies equally to leases when the total amount owed under the lease reaches $30,000. Contracts below that figure can be handled through less formal purchasing at the authority’s discretion.
Splitting purchases is prohibited. A single procurement that totals $30,000 or more cannot be broken into smaller orders to slip beneath the threshold. There is one safe harbor: if an awarding authority reasonably relied on prior-year spending to project that total expenditures would stay under $30,000, and unforeseen circumstances later pushed the number higher, the earlier unbid purchase is not itself a violation as long as the authority bids the additional expenditure.
The $100,000 Threshold for Public Works
Public works contracts follow Title 39, and the bidding threshold is significantly higher. Sealed competitive bids are required only when the contract exceeds $100,000.2Alabama Legislature. Alabama Code 39-2-2 – Advertisement for and Opening of Bids Projects at or below that amount can be awarded with or without advertising or sealed bids.
Advertising requirements differ by the type of awarding authority. The state, a county, or a county instrumentality must publish notice at least once a week for three consecutive weeks in a newspaper of general circulation in the county where the work will happen. A municipality only has to advertise once in a local newspaper of general circulation. If no newspaper is published in the municipality, notice goes on a bulletin board outside the purchasing office and to the Department of Finance for publication on the state’s centralized website.
The anti-splitting rule applies here too. No project exceeding $100,000 may be carved into smaller pieces of $100,000 or less to duck the bidding requirement.
Alabama does not require performance and payment bonds on public works contracts of $100,000 or less. On larger jobs, the awarding authority typically requires bid security of at least 5% of the estimated project cost, capped at $10,000.
What Is Exempt From Competitive Bidding
Even purchases above the threshold can be exempt if they fall into one of the categories the Legislature carved out. The most common exemptions:
- Professional services from attorneys, physicians, architects, engineers, certified public accountants, consultants, appraisers, and similar professionals whose individual skill and judgment drive the work.3Alabama Legislature. Alabama Code 41-16-51 – Contracts for Which Competitive Bidding Not Required
- Insurance policies of any type.
- Fiscal or financial advice.
- Utility services at rates fixed by law, regulation, or ordinance.
- Sole-source purchases, meaning goods or services available from only one supplier, or purchases whose nature makes competitive bidding impossible.
Local governments can also buy goods through approved national or regional purchasing cooperatives without going through sealed bidding. Several conditions attach: the cooperative’s bid process has to be reviewed and approved by the Alabama Department of Examiners of Public Accounts for each bid, the goods must either be unavailable on the state purchasing program or priced at or below the state program price, and the purchase should go through a participating Alabama vendor when one exists.4Alabama Legislature. Purchasing Cooperatives As of early 2026, approved cooperatives include Sourcewell, TIPS, BuyBoard, and Omnia Partners, among others. The exemption covers goods only, not related service contracts.
Emergency Purchases
When an emergency threatens public health, safety, or convenience, an awarding authority may skip formal advertising and let contracts immediately, but only to the extent needed to address the danger. The authority must declare the emergency in writing, explain the specific risk that makes delay unacceptable, and make the declaration public. State agencies operate under a parallel rule under Article 5 of Chapter 4, with the Chief Procurement Officer or a purchasing agency head authorizing emergency procurements based on a written determination in the contract file.5Alabama Legislature. Alabama Code 41-4-136 – Emergency Procurements Even in an emergency, the buyer must seek as much competition as circumstances allow.
How Bids Are Solicited and Opened
For local contracts at the $30,000 threshold, the awarding authority must post notice on a bulletin board outside the purchasing office and send notice by mail or electronic means to every vendor that has filed a written request to be on the bid list for the items involved.6Alabama Legislature. Alabama Code 41-16-54 – Advertisement for and Solicitation of Bids A vendor that fails to respond to three consecutive notifications can be dropped from the list.
Specifications must be detailed enough that all bidders compete on equal footing. Bids are submitted sealed and opened publicly. If any bid’s terms are disclosed before the public opening, the whole proceeding is void and the authority has to start over with a new advertisement.
Since 2009, local awarding authorities have also had the option of using a reverse auction, in which anonymous suppliers submit progressively lower bids online. The item bought this way must either be unavailable on the state purchasing program or priced better than the state program, and the Department of Examiners of Public Accounts oversees and audits the process.
Awarding the Contract
Alabama law directs contracts to the “lowest responsible and responsive bidder.” Those two words are not interchangeable. A responsible bidder is competent, experienced, and financially capable of performing the work. A responsive bidder submitted a bid that actually complies with the invitation’s terms and conditions.7Alabama Legislature. Alabama Code 39-2-6 – Award of Contract Minor irregularities do not automatically make a bid non-responsive.
The authority can reject all bids if they are unreasonable or if accepting any of them would not serve the public interest. On public works contracts where every bid exceeds available funding, the authority can negotiate with the lowest responsible and responsive bidder if it documents the shortfall, if time is pressing, if the negotiations are in the public interest, and if the changes do not materially alter the project’s scope.
If the winning bidder refuses to sign the contract, post the required bonding, or produce proof of insurance, the authority can move to the second-lowest bidder, and then to the third if necessary. On public works, an authority can also evaluate bids based on lowest life cycle cost rather than sticker price, but only if the invitation to bid said so and laid out the evaluation criteria up front.
Penalties for Violating the Bid Law
Two consequences attach to any contract awarded outside the competitive bid rules.
First, the contract is void as a matter of law. The government owes nothing under it, and the vendor cannot enforce it. Second, anyone who violates the bid law is guilty of a Class C felony, punishable by one to ten years in prison.
Bid Rigging and Collusion
Any agreement among bidders to fix prices, refrain from bidding, or otherwise restrain competition voids the affected bids and disqualifies the colluding bidders from submitting future bids to that awarding authority. Criminal penalties scale with contract value: collusion on contracts of $30,000 or less is a Class A misdemeanor, and collusion above $30,000 is a Class C felony.
Conflicts of Interest
No officer or member of a municipal governing body or municipal board may hold a direct or indirect financial interest in a purchase or contract subject to the bid law. Violation is a misdemeanor carrying up to 12 months in jail, a fine of up to $500, or both. A willful violation also removes the official from office.
Bid Protests and Vendor Debarment
For state-level procurements, a vendor that believes a solicitation was unfair or an award improper can file a written protest with the Chief Procurement Officer. The protest must identify the procurement, state the grounds, and include supporting evidence.8Alabama Administrative Code. Alabama Administrative Code Rule 355-4-6-.01 – Bid Protests A protest filed before award stays the procurement until it is resolved, unless the Chief Procurement Officer determines in writing that moving forward is necessary to protect the state’s interests. Article 3 does not set out a matching protest procedure for local government procurements, so aggrieved bidders at the local level typically pursue judicial remedies.
Vendors that commit fraud, repeatedly fail to perform, or violate other standards of conduct can be debarred from state contracts for up to three years. The Chief Procurement Officer can also suspend a vendor for up to three months during an investigation, and the vendor’s bids will not be solicited or considered while the suspension is in effect.9Legal Information Institute. Alabama Administrative Code Rule 355-4-6-.02 – Authority To Debar and Suspend
Federal Money Brings Federal Rules
When an Alabama government spends federal grant money, another layer of procurement rules applies on top of the state bid law. The federal Uniform Guidance at 2 CFR Part 200, Subpart D, requires open competition, a domestic preference, and specific contracting methods keyed to the dollar amount involved.10eCFR. 2 CFR Part 200 Subpart D – Procurement Standards The federal micro-purchase threshold is currently $15,000, and the simplified acquisition threshold is $350,000. Following Alabama’s competitive bid law on a federally funded purchase does not by itself satisfy the federal requirements around cost analysis, contractor responsibility, and required contract provisions. Getting the state rules right and the federal rules wrong can put the grant funding itself at risk.
