Vermont Construction Estimating Services

Vermont is not like the rest of New England. Various out-of-state estimates miss that. There’s Act 250; it is the state’s land review process. It adds extra permit steps that need to be considered. The energy code of this state is also stricter than most other states. This means insulation and mechanical systems cost more. Secondly, hilly terrain and rural roads make excavation and material delivery more expensive. Labor availability also affects the timeline and overall expense. SMA Estimating LLC covers all factors to generate accurate estimates. A bid that ignores these rules can lose money or lose the job.

Vermont does not license general contractors. It does license electricians and plumbers through the Division of Fire Safety, so those trades must be done by licensed people.

Home building is different. From April 1, 2023, onwards, a residential contractor shall be required to register with the OPR if the project exceeds $10,000.

A registered contractor must:

• Carry liability insurance of $1 million per occurrence and $2 million total
• Sign a written contract with the homeowner before work starts.

We mark which parts of your takeoff need a licensed trade and remind you to check a sub’s registration before you lock a price.

Vermont has its own wage rule for some state-funded work. It is in 29 V.S.A. § 161. It covers:

• State construction projects costing more than $100,000
• Projects costing more than $200,000 and more than 50 percent financed by a capital construction act.

Every worker on these jobs must get at least the state’s average local wage, plus 42.5% for benefits. The Department posts new rates each July. The current list runs from July 1, 2026 to June 30, 2027. Federal money brings the federal Davis-Bacon rules instead. We find out early who is paying, then price the labor the right way.

When a state project costs more than $50,000, the Commissioner of Buildings and General Services must advertise it publicly or invite at least three bids. That is the rule in the same statute, 29 V.S.A. § 161. We read each bid package for its dates, forms, and bond terms.

Bond rules depend on the owner. On Agency of Transportation work, for example, the state may waive the performance bond only on contracts of $100,000 or less. Because owners differ, we show bond cost as its own line in your estimate. It does not hide in overhead.

Vermont writes its own energy codes. The Public Service Department runs both of them, and you can read about them on its building energy standards page.

• RBES is the residential code. It covers new homes, additions, and repairs for buildings up to three stories.
• CBES is the commercial code. It covers commercial buildings and buildings four stories or taller.

A new regulation has come into force on July 14, 2026. Builders have two options to choose from: either use the 2020 or the 2024 edition of each code. Also, the residential stretch code is the reference used in Act 250 projects. It will affect insulation and heating prices

So, please tell us which one your team selected.

The Division of Fire Safety implements the 2025 Vermont Fire and Building Safety Code. This new code was implemented in the latter part of 2025. 

The 2025 code implements:

• 2021 versions of NFPA 101 and NFPA 1
• International Building Code
• International Existing Building Code

Other codes used include the 2023 version of the National Electrical Code and the 2024 International Plumbing Code.

By state definition, a public building includes all buildings except for owner-occupied single-family homes. Few other buildings are not included in the definition of public buildings. These other types of buildings are registered home daycares and farm buildings. 

The items that are checked during the construction permit review, such as sprinklers, alarms, exits, and others, are highlighted by us.

Act 250 is Vermont’s land-use law. A project needs an Act 250 permit in these cases:

• Commercial or industrial work on more than 10 acres, or on more than one acre in a town without permanent zoning and subdivision rules
• Ten or more housing units.

Act 181 of 2024 is changing this. A new Land Use Review Board replaced the Natural Resources Board, and a tier system now looks at where a project sits. Towns in the fully exempt tier need no Act 250 permit. Another tier exempts housing of up to 50 units on 10 acres or less. Local zoning permits still apply. A permit can add months, so we ask early whether Act 250 may apply and note it in your schedule assumptions.

Water rules shape many Vermont sites.

• Stormwater: Construction that disturbs one acre or more, or that is part of a larger plan reaching one acre, needs coverage under the state’s Construction General Permit 3-9020.
• Rivers: Following the floods of 2023, the Flood Safety Act granted the Agency of Natural Resources jurisdiction for development in mapped river corridors in streams that have watersheds of two square miles or larger.
• Timing: The flood hazard and river corridor standards will be implemented on January 1, 2028.

Before we estimate sitework, we ask for the flood zone or any mapped river corridor. Erosion control and stormwater measures then get their own lines.

The Vermont Department of Taxes explains the rules on its contractor tax page.

• The sales tax rate is 6%. Some towns add a 1% local option tax.
• A contractor pays the tax when buying materials and does not charge the customer tax on them.
• If a seller does not charge Vermont tax, the contractor owes use tax at 6% directly to the state. The local option tax does not apply to use tax.
• For a qualified exempt project, a contractor can use Form S-3C to avoid tax on materials built into that project.

We state the tax we assumed on every estimate. For your own case, check with the Department of Taxes or your tax advisor.

Smaller house jobs often get their numbers in one to two days. Larger commercial work is planned around your bid date.

• Clear funding sources make pay rates transparent from the start.
• Energy code standards are checked before pricing walls, windows, and HVAC.
• Major trades are split up to make comparing bids easy.
• Stormwater, erosion control, and flood work get listed on separate lines.
• Every assumption is written down so costs are easy to explain to the owner.
