Make Sure You Are Using the Right Building Office
This is one of the most important local details. The County’s Community Development Department states that its Building, Permitting & Inspections staff handles projects within Fauquier County, the Town of Remington and the Town of The Plains. The Town of Warrenton maintains its own building department.
| Property location | Building permit authority | Important note |
|---|---|---|
| Unincorporated Fauquier County | Fauquier County | County building and zoning processes generally apply. |
| Town of Remington | Fauquier County for building | Obtain the Town zoning approval required for the project and provide it with the County building application. |
| Town of The Plains | Fauquier County for building | The Town administers its zoning requirements; submit applicable Town zoning approval with the building permit. |
| Town of Warrenton | Town of Warrenton | Use the Town’s Community Development / Building Safety office instead of the County building office. |
If the property is within Warrenton town limits, use the Town of Warrenton building and zoning permit page. The Town lists Building Department assistance at 540-347-1101 on its current permit page.
What Work Usually Needs a Fauquier County Building Permit?
Most new construction, structural alterations and regulated electrical, plumbing or mechanical work require permits. Zoning approval is also required for many projects, so do not look only at the building-code side of the job.
| Project | What to expect |
|---|---|
| New house | Building/zoning permit, plans, site information and applicable well, septic, utility, entrance and land-disturbance approvals. |
| Home addition | Building and zoning review normally required. Setbacks and site limitations should be checked before plans are finalized. |
| Finished basement | A permit is required. Additional zoning review can apply when bedroom configuration or dwelling-unit arrangements change. |
| Deck or porch | Permit requirements depend on the project. Fauquier provides project-specific deck guidance and online submission options. |
| Accessory structure / shed | Structures generally require approval, but certain single-story residential storage structures of 256 sq. ft. or less may be exempt from a building permit. Zoning rules still apply. |
| Electrical, plumbing, mechanical or gas | Trade permits are required for regulated work. Simple like-for-like ordinary repairs may be exempt. |
| Swimming pool or spa | Permit and safety-barrier requirements may apply depending on the pool or spa. |
| Commercial construction or tenant alteration | Building, zoning and often site-plan or other development review may be required. |
| Demolition | A building permit is required for regulated demolition work. |
Some work may not need a building permit
Examples identified by County guidance include certain ordinary repairs, some fences that are not pool barriers, at-grade patios without a roof or railing, and qualifying small residential storage structures. However, permit-exempt does not mean rule-exempt. Setbacks, zoning, well/septic separation, easements and other restrictions can still control where or how the work is done.
For a project-specific decision, start with the County’s residential construction guidance or call 540-422-8230 before buying materials.
Do These Checks Before You Submit an Application

Fauquier County states that delinquent real-estate taxes and other qualifying liens must be paid before permit issuance or approval. Do not wait until the end of plan review to discover this issue.
A new house, bedroom change, accessory structure with plumbing or other project affecting an onsite system may need Health Department approval.
Significant clearing, grading or soil disturbance can trigger additional erosion, sediment or stormwater review. For complicated sites, address this before the building application is submitted.
County residential guidance states that property subject to a Fauquier County conservation easement can require a County Attorney compliance/concurrence form with the application.
How to Apply for a Fauquier County Building Permit
The exact package depends on the project. The County offers online submission for several permit types and continues to maintain application forms and checklists for other projects.
- Open the official portal. Go to the Fauquier County Land Development Online Portal.
- Create or sign in to your account. New users select Login or Register. County staff approve newly created accounts during regular business hours.
- Select “Apply.” Choose the permit category that matches the work. Read the description shown for the permit type before starting.
- Add the project location. At least one location is required for an online permit application.
- Enter the property, owner and applicant information. Use the legal owner and project details requested on the form.
- Upload required files. Depending on the job, this can include plans, plats, contractor information, soils documentation, zoning information or project-specific affidavits.
- Submit the complete application. Incomplete applications can be returned or delayed.
- Monitor the portal and your email. Respond promptly if a reviewer requests corrections or additional material.
- Pay the required balance. The County collects minimum/base fees as required during the process and the remaining permit amount before issuance.
- Do not begin regulated work until the permit is issued. Keep approved plans and permit documents available during construction.
Documents to Prepare Before Applying
Preparing a complete package is one of the easiest ways to avoid a frustrating second trip or resubmission. Requirements vary, but these are common items to check.
- Completed Building/Zoning Permit Application when applicable.
- Property owner and applicant contact information.
- Property Identification Number and project address.
- Clear description of the proposed work.
- Contractor identification and applicable licensing/business information.
- Scaled building plans for projects requiring plan review.
- Plat or site drawing showing the structure and distances from property lines.
- Shrink/swell soils documentation when required.
- Health Department well/septic approval when applicable.
- Public water/sewer approval where required.
- VDOT entrance approval for projects that require it.
- Conservation-easement concurrence documentation when applicable.
- Deed copy if ownership recently changed and County real-estate records have not yet been updated.
- Project-specific forms such as pool, demolition, trade, accessory-structure or commercial documents.
For projects requiring building-plan review, Fauquier’s plan-review guidance states that plans must provide enough dimensional and technical detail for reviewers to understand the proposed construction. Use the current Community Development forms library instead of relying on an old downloaded form.

What Happens After You Submit?
Most permit applications do not go straight from the counter to approval. Depending on the job, the application can move through building-plan review, zoning and erosion/stormwater review.
For several residential project types, Fauquier states that a complete application can generally take about 2-3 weeks for review. This is not a guaranteed turnaround time. Incomplete plans, corrections or high application volume can extend the process.
- Permit staff check the application package.
- Zoning reviews the use, setbacks and other zoning issues when required.
- Building staff review construction plans for code compliance.
- Environmental or land-development staff review applicable site issues.
- The applicant is contacted if revisions are required.
- Corrected material is resubmitted when necessary.
- After approvals are complete, permit staff calculate the remaining amount due.
- The permit is issued after required fees and conditions are satisfied.
How to Schedule a Fauquier County Building Inspection
Every building permit requires a final inspection, and many projects require several inspections before work is covered. The permit holder is responsible for requesting the correct inspection at the correct stage.
Online inspection request
- Sign in to the Fauquier County permit portal.
- Select My Work.
- Open the permit that needs an inspection.
- Select the Inspections tab.
- Choose the available inspection type.
- Select Request Inspection.
- Choose an available date and add access notes or a gate code if needed.
- Submit the request and confirm that the portal shows a successful request.
The County’s current guidance says inspection requests for the next day must be entered before 3:00 p.m., subject to schedule availability. Weekends, holidays and dates where the inspection schedule is already full may not be selectable.
What to do on inspection day
- Keep the approved plans at the jobsite in an accessible location.
- Do not conceal work that still needs inspection.
- Give the inspector any gate code or access instructions.
- An adult must be present before an inspector enters an occupied structure.
- Check the County’s Today’s Inspections information for the estimated time window.
- Allow roughly one hour before and one hour after the displayed estimated time.
The County notes that inspections are often available the next business day, although busy periods can push scheduling farther out.

Third-party inspections
Fauquier has an approved third-party inspection program. The County states that specific buildings and commercial inspections other than final inspections may be performed by registered third-party inspectors when the program requirements are followed. The property owner pays the third-party inspection cost.
Do not simply hire an inspector and assume the report will replace a County inspection. Use the County’s approved agency list and required reporting process.
Building Codes Used in Fauquier County in 2026
Fauquier County enforces Virginia’s statewide building-code system rather than creating a separate local construction code. The County identifies the 2021 Virginia Uniform Statewide Building Code as the applicable adopted code framework. Virginia’s 2021 codes became effective on January 18, 2024.
The framework includes rules for new construction, residential construction, existing buildings and other regulated building work. Fauquier also maintains local zoning, subdivision, erosion/stormwater and development requirements that can affect a project even when the construction itself complies with the statewide building code.

Common Problems That Delay a Fauquier County Permit
| Problem | What to do instead |
|---|---|
| Applying to the wrong jurisdiction | Confirm whether the site is County jurisdiction or inside the Town of Warrenton before preparing the application. |
| Ignoring zoning until after plans are finished | Check use, setbacks and building placement before paying for final construction drawings. |
| Missing property plat or dimensions | Show proposed construction and required distances clearly on the site information requested by the County. |
| Missing well/septic approval | Contact the Health Department early when private systems or bedroom changes are involved. |
| Incomplete plans | Use the County’s project-specific checklist and make sure drawings contain enough detail for code review. |
| Outstanding real-estate taxes or liens | Resolve applicable delinquent amounts before permit issuance. |
| Covering work before inspection | Request footing, framing, rough trade and other required inspections before the work becomes inaccessible. |
| Permit becomes inactive | Keep inspections moving. County permit materials state that inspections are important at six-month intervals to show that construction continues. |
| Skipping the final inspection | Pass the required final and obtain a Certificate of Occupancy when the project requires one. |
Permit Completion and Certificate of Occupancy
Passing rough inspections does not close a permit. Fauquier requires a final inspection on every building permit. New homes and other projects that require occupancy approval must also receive a Certificate of Occupancy before the building is legally occupied.
For a new dwelling, County guidance states that the Certificate of Occupancy cannot be issued until required building inspections have passed, the final erosion and sediment inspection has been approved, and applicable Health Department or public utility occupancy releases are complete. The County notes that processing the CO may take up to 48 hours after the required items are satisfied.
