Virginia Performance BondThe $500,000 Threshold, Explained
You may have read that Virginia's public-works bond kicks in at “$100,000.” That number is wrong for the question most contractors are actually asking. Under Va. Code § 2.2-4337 — Virginia's Little Miller Act — a nontransportation public construction contract over $500,000 must carry both a performance bond and a payment bond, each equal to 100% of the contract. The $100,000 mark only opens a band where the public body can swap bonds for contractor prequalification. Below, the full threshold ladder, plus why the Northern Virginia data-center boom is pulling so many subcontractors into bonding for the first time.
Virginia Runs a Threshold Ladder, Not a Single Cutoff
Ask three Virginia contractors when bonds kick in and you may get three different dollar figures — because the Virginia Public Procurement Act (VPPA) never set one. It built a ladder instead, and where your project sits on it depends on two things: the dollar value and whether the funding is transportation or nontransportation. Get those two facts straight and the bonding answer falls out cleanly.
Below the bottom rung, the public body still may require bonds — § 2.2-4337(E) preserves that right at any dollar value. In the middle band, the body chooses between bonds and prequalifying contractors for the specific project. At the top, bonding is mandatory and equals 100% of the contract for both the performance bond and the payment bond. Most public construction of any real size ends up needing the paired performance and payment bond written on the same project.
Virginia Public Construction Bond Threshold Ladder
Where your contract sits determines whether bonds are mandatory, optional, or replaceable by prequalification
Nontransportation $100K–$499K
Optional
Public body may require bonds OR prequalify contractors per project and waive them (prequalification substitutes for bonds).
Transportation $250K–$349K
$350K floor
Agency may waive only if the bidder proves a surety declined to write the bond.
Transportation > $350K
Mandatory
Performance + payment bonds required under Va. Code § 33.2-208 et seq.
Nontransportation > $500K
Mandatory
Both bonds required at 100% of contract under § 2.2-4337. The non-negotiable trigger.
Va. Code § 2.2-4337 (nontransportation) and § 33.2-208 et seq. (transportation); federal Miller Act applies separately at > $150,000
The “$100,000” myth: $100,000 is not a bonding trigger. It is the floor of the prequalification-substitution band. A nontransportation contract becomes mandatorily bonded only when it exceeds $500,000. If you priced a bid around a $100,000 assumption, you may have either over- or under-budgeted your bonding line.
Why Loudoun County Is Bonding Subs Who Never Bonded Before
Northern Virginia is the densest data-center market on earth. Industry tracking puts Loudoun County and its neighbors at roughly 90% of Virginia's data-center permits, with thousands of megawatts under construction across Ashburn and Leesburg. That construction footprint is what makes Virginia performance bonds a live question for far more contractors than the statute alone would suggest.
Two bonding pressures stack on a data-center program. First, the public side: the access roads, water and wastewater capacity, substation tie-ins, and right-of-way work that surround a campus are frequently procured by counties and utilities as public construction — and at data-center scale those packages clear the $500,000 nontransportation trigger easily, pulling them into § 2.2-4337 bonding. Second, the private side: hyperscale owners and their general contractors require performance and payment bonds by contract on the building shell, electrical, and mechanical scopes regardless of any statute. A single concrete or electrical subcontractor on one data hall can be carrying a seven-figure bonded scope.
The result is that mid-size GCs and specialty subs feeding the Ashburn pipeline are getting asked for bonds on work they used to take unbonded. The constraint is rarely the premium — it is whether the surety will extend enough aggregate capacity to cover several concurrent data-center scopes at once.
~90% of VA Permits
Loudoun County and Northern Virginia account for the overwhelming majority of the state's data-center permitting (industry data).
Public + Private Stack
Tied infrastructure hits the § 2.2-4337 public trigger; the campus itself hits owner-required private P&P bonds.
Aggregate Is the Squeeze
Running multiple concurrent halls means your bonded backlog, not any single job, is what your surety has to underwrite.
Official Virginia Requirements
"Upon the award of any (i) public construction contract exceeding $500,000 awarded to any prospective contractor... such contractor shall furnish... a performance bond in the sum of the contract amount... and a payment bond in the sum of the contract amount."Code of Virginia, Virginia Public Procurement Act • Va. Code § 2.2-4337

Payment Bond Claims: The Rule That Turns on Who You Contracted With
Virginia's payment-bond claim mechanics under § 2.2-4341 hinge on one question subcontractors often miss: did your contract run to the prime, or to another subcontractor?
Direct Contract With Prime
A claimant who contracted directly with the prime contractor may sue on the payment bond without first sending the 90-day notice. The contractual relationship is the notice.
Contract With a Subcontractor
If your contract is with a sub (not the prime), you must give the prime written notice within 90 days of last furnishing labor or materials, by registered or certified mail. Retainage claims are exempt from this notice.
Suit Window
After the 90-day notice period, suit must be filed within one year of the last day labor or materials were furnished. Miss it and the claim is barred regardless of merit.
On waivers: Any waiver of these payment-bond rights must be in writing and signed after the labor or materials were furnished. A waiver pre-printed into the original subcontract does not extinguish your claim. Keep certified-mail receipts as proof of timely notice, and read the controlling text of § 2.2-4341.
Your DPOR License Bond Is Not a Project Bond
Virginia contractors routinely confuse the bond they post to get licensed with the bond a public owner demands on a job. They protect different people and do not substitute for each other.
DPOR Contractor License Bond
- Class A option: a $50,000 license bond as an alternative to showing $45,000 net worth
- Carries a $20,000 per-claim cap — not 100% of any project
- Protects consumers against regulatory and licensing violations
- Tied to your license class (A: $150K+ single or $1M+/yr; B: $30K–$149,999; C: $1K–$29,999)
- One standing bond — details on the Virginia contractor license bond page
Project Performance & Payment Bond
- Written per project at 100% of the contract amount
- Guarantees completion (performance) and pays subs and suppliers (payment)
- Mandatory above the VPPA thresholds; filed with the awarding public body
- Surety must be authorized in Virginia and (above $150K federal) Treasury-certified
- Underwritten on your bonding capacity, not a flat license fee
One sentence to remember: the $50,000 DPOR bond with its $20,000 cap does nothing to satisfy a $2 million public-contract performance bond. They are separate instruments serving separate beneficiaries.
What a Virginia Performance Bond Costs
Premium is a percentage of the contract value, not a flat fee. Industry pricing for contract bonds runs roughly 0.5% to 3% (a tiered estimate, not a published rate), with the strongest credit and financials landing under 1%. On a $1,000,000 data-center subcontract, that spread is the difference between roughly $5,000 and $30,000 a year — which is why your financial documentation matters as much as the bid itself.
Credit sets the baseline, but sureties also weigh working capital, net worth, years in business, your largest completed project, and current backlog. A contractor with a 720 score but a thin balance sheet can price higher than one with a 680 and strong working capital. For the full breakdown of pricing inputs, see our surety bond cost guide, or model a specific job with the performance bond calculator and the combined performance-and-payment calculator.
Because Virginia requires both bonds together above threshold, request them as a pair — the combined rate is more economical than buying a standalone payment bond and a performance bond separately.

From the Producer's Desk: Sizing Capacity for Loudoun Data-Center Scopes
Here is the trap that catches subs new to the Ashburn pipeline. A data-center program does not hand you one bond and wait for you to finish before issuing the next. A single hyperscale GC may be carrying several scope packages at once — a shell concrete pour here, a switchgear and busway install there, chilled-water mechanical on a third building — with individual values anywhere from $5 million to $50 million, and the award letters land weeks apart, not years. So the question an underwriter is really answering is not “can you bond this $20 million scope” but “how much bonded work can you have open at the same moment without us running out of room.” That ceiling — your open-backlog headroom — is what data-center scope stacking attacks, and it is where subs who only ever ran one bonded job at a time get told no on package number three.
Sureties build that headroom off your financial statements, not your credit pull. They read working capital and net worth, watch the two- and three-year trend, and then ask how much uncompleted bonded value you can absorb before the balance sheet is stretched too thin to backstop the next default. For Loudoun work the binding constraint is almost never any one package — it is the sum of the concurrent ones. A sub whose statement supports plenty of room for a lone $15 million scope can still be short the headroom to carry that scope plus two more stacked on top of it during the same fiscal year. The fastest way to widen the ceiling is the quality of the accounting itself: the same revenue underwrites far more open backlog on a CPA-reviewed or audited statement than on cash-basis books, because the surety can trust the numbers it is lending capacity against. That upgrade is the single most useful move a sub can make before the first data-center bid.
The expertise is plain: chasing back-to-back Northern Virginia packages is a backlog-headroom conversation, not a one-bond transaction. To estimate where your current numbers leave room before you sit down with an underwriter, start with the bonding capacity calculator, then read our walkthrough of little Miller Act thresholds across the states so you know which jobs in your pipeline actually require a bond.
Quick Read: Which Virginia Bond Does Your Job Need?
Federal Work in Virginia: When the Miller Act Takes Over
Virginia carries an unusually heavy federal construction load — the Pentagon and the federal footprint across Northern Virginia, the U.S. Army Corps of Engineers Norfolk District, and military installations statewide. On any of those federally funded jobs, state thresholds are irrelevant: the federal Miller Act governs, requiring performance and payment bonds on contracts over $150,000, each at 100% of the contract.
The law that applies depends on who is paying, not where the dirt is. A federally funded project sitting next to a county-funded one in the same corridor can run on two different bonding frameworks. If your pipeline mixes both, you need to read each solicitation for which statute it cites. Our federal government-contract performance bonds page covers Treasury Circular 570, the SBA Bond Guarantee program, and the federal pre-award bid bond.

Subcontractor Bonds and the New Per-Task Option for Localities
Two provisions in § 2.2-4337 matter specifically to subs and to anyone bidding indefinite-delivery work. First, § 2.2-4337(F) lets a prime contractor require its subcontractors to furnish payment bonds — so on a large Virginia public job, you may be asked for a sub-tier payment bond even though your contract is one layer down from the public owner.
Second, under 2022 and 2023 amendments codified at § 2.2-4337(G), a locality may by ordinance allow performance and payment bonds to be furnished per task on indefinite-delivery/indefinite-quantity (IDIQ) contracts. Instead of bonding an entire multi-year umbrella agreement up front, the bond attaches to each task order as it is issued. For a contractor on a large IDIQ vehicle, that can dramatically reduce how much capacity is tied up at any one time — but it only applies where the locality has actually adopted the ordinance, so confirm it in the contract documents.
If you are weighing whether your numbers support a sub-tier or per-task bond program, the bonding capacity calculator is the fastest first pass, and the performance bond hub covers how requirements differ in other states — for example, Florida's public-construction bonding rules set a different threshold and notice scheme than Virginia's.
Virginia Performance Bond Questions Contractors Ask
Answers grounded in the Virginia Public Procurement Act and Va. Code §§ 2.2-4337 and 2.2-4341
Is the Virginia performance bond trigger $100,000 or $500,000?
For nontransportation public construction, the mandatory trigger is $500,000, not $100,000 -- a figure several competing pages get wrong. Under Va. Code Section 2.2-4337, any nontransportation public construction contract that exceeds $500,000 must carry both a performance bond and a payment bond, each equal to 100% of the contract amount. The $100,000 figure is only the bottom of a different band: between $100,000 and $500,000, the public body has a choice -- it may require bonds, OR it may prequalify contractors for that specific project and waive the bonds entirely. So $100,000 is where the option begins; $500,000 is where bonding becomes non-negotiable.
Why is the threshold lower ($350,000) on Virginia road and transportation projects?
Transportation-funded construction governed by Va. Code Section 33.2-208 et seq. runs on its own, lower mandatory threshold of $350,000. Between $250,000 and $349,999 on a transportation project, the agency may waive bonds only if the bidder proves a surety actually declined to write the bond -- a much narrower escape hatch than the prequalification path on the nontransportation side. The practical effect: a VDOT-funded job and a city building project of the same dollar value can have completely different bonding obligations. Always read which statute the invitation for bids cites.
How much bonding capacity do I need to chase a Loudoun County data-center subcontract?
Data-center general-contract packages in Ashburn and Leesburg routinely run well past $500,000, and electrical, mechanical, and concrete subcontract scopes on a single hall can themselves clear seven figures. That means two bonding pressures stack: the public-side Little Miller Act on any tied infrastructure work, and the private owner or GC who requires performance and payment bonds by contract. Sureties size you with a single-job limit (the largest one contract they will bond) and an aggregate limit (total bonded backlog). Both come primarily off your financial statements -- working capital and net worth -- not your credit score. A sub planning to run two or three concurrent data-center scopes needs aggregate capacity that covers all of them at once, which is usually why CPA-reviewed or audited statements come before the first bid.
When must a subcontractor give notice to claim against a Virginia payment bond?
Under Va. Code Section 2.2-4341, a claimant who has a direct contract with the prime contractor can sue on the payment bond without prior notice. But a claimant whose contract is with a subcontractor (not the prime) must give the prime written notice within 90 days of the last day they furnished labor or materials, sent by registered or certified mail. After that 90-day window, suit must be filed within one year of the last day of furnishing. Retainage claims are exempt from the 90-day notice requirement. Any waiver of these bond rights has to be in writing and signed after the work is performed -- a pre-printed waiver buried in the original subcontract will not bind you.
Does my $50,000 DPOR Class A contractor license bond cover a public project?
No. The license bond a Class A contractor may post with the Department of Professional and Occupational Regulation (a $50,000 bond, as an alternative to showing $45,000 net worth) is a licensing requirement with a per-claim cap of $20,000. It exists to protect consumers against regulatory violations, not to guarantee completion of a specific public contract. A public body awarding a $2 million job will require a separate project performance bond at 100% of that contract -- the DPOR bond does nothing for it. The two are entirely different instruments; see our Virginia contractor license bond page for how the DPOR side works.
Can a Virginia public body require a bond on a project under $500,000?
Yes. Va. Code Section 2.2-4337(E) expressly lets a public body require performance and payment bonds on contracts below the statutory thresholds if it chooses to. Localities also have added flexibility: under 2022 and 2023 amendments, a locality may by ordinance allow per-task performance and payment bonds on indefinite-delivery/indefinite-quantity contracts, so the bond attaches to each task order rather than the whole umbrella agreement. The takeaway for contractors: never assume a sub-threshold job is bond-free. The bond requirement lives in the solicitation documents, and a public owner is allowed to set it lower than the statute floor.
