Regulatory and utility information last reviewed: August 2026

Virginia solar permit requirements start with one statewide building code, but every application still gets reviewed locally. A typical residential or light-commercial project needs building and electrical approval from the locality, interconnection approval from Dominion Energy, Appalachian Power, a cooperative, or a municipal utility, and sometimes a separate HOA, historic district, or fire review on top of that.

Virginia solar interconnection requirements depend on project capacity, customer class, export configuration, and utility territory. A Dominion net metering application can carry different sizing and standby charge considerations than an Appalachian Power or cooperative project, and Virginia solar permitting overall has picked up real momentum after the Commonwealth passed a batch of solar and storage bills in 2026.

This guide covers the 2021 Virginia Uniform Statewide Building Code, DPOR contractor licensing, the developing Smart Solar Permitting Platform, utility interconnection, Virginia net metering law, coastal wind design, and the submission problems that slow projects down most often.

Virginia uses one statewide building code, but that does not add up to one statewide approval process. Local departments issue permits, the serving utility reviews interconnection, DPOR regulates who can contract for which scope of work, and coastal structural criteria vary by site.

Virginia runs one statewide code, which already sets it apart from home rule states where every county writes its own rulebook. The Uniform Statewide Building Code, or USBC, is adopted by the Board of Housing and Community Development and enforced by local building departments. The current cycle took effect January 18, 2024, is based on the 2021 I-Codes, and incorporates the 2020 National Electrical Code.

One code does not mean one process. Staffing, interpretation, and requested documentation still vary by AHJ, so a plan set that sails through in one county might get flagged in the next one over. Historic district review and local ARC overlays can add another layer on top of the standard building and electrical review.

Yes. The USBC applies throughout the Commonwealth and local departments enforce it. The 2021 cycle, effective since January 18, 2024, incorporates the 2020 NEC, so a locality cannot swap in an unrelated older code. Confirm local submission procedures and required documentation before assuming the process looks the same everywhere.

The local building department issues and enforces both the building and electrical permits under the USBC. Most permanent rooftop and ground mounted PV projects need approval on both scopes, whether that happens under one permit number or two separate ones with different officials and forms.

Virginia authorized a statewide Smart Solar Permitting Platform in 2026. It is one of Virginia’s most consequential recent changes for residential solar permitting, and it arrives while SEIA ranks Virginia 9th nationally for installed solar capacity. Do not assume the platform is live everywhere yet.

The law, codified at Code of Virginia section 45.2-1735, sets up an automated review pathway for qualifying residential systems. Virginia Energy is tasked with establishing and launching the platform by July 1, 2027, and localities must begin accepting the state platform or an approved alternative automated platform by January 1, 2028. Confirm both dates against the final enacted text before quoting a timeline to a customer.

Virginia Energy administers the platform, which is a different agency than DHCD, the body that sets the USBC itself. Funding passed for an implementation workgroup in the first year of the program, so 2026 is better understood as a rollout year rather than the year every locality flips a switch. Automated approval covers qualifying residential systems that comply with the USBC and applicable state law. Inspections stay local, and zoning, historic district, HOA, and utility approval remain separate steps even once a locality is fully on the platform.

Not everywhere. The platform is authorized and funded for implementation, with a hard deadline requiring localities to accept it or an approved alternative by January 1, 2028. Check with each locality directly rather than assuming statewide availability in 2026.

A handful of localities adopted SolarAPP+ on their own well before the statewide platform came along. This local adoption is separate from the state effort described above.

Virginia licenses at the business level through the DPOR Board for Contractors, and this trips up installers coming from states that license individual solar installers directly. A firm needs the right Class A, B, or C license, which controls maximum project and annual contract value, plus the classification or specialty that controls what type of work the business may actually contract to perform.

Solar contractors in Virginia should pay close attention to the Alternative Energy System specialty, abbreviated AES. It covers installation, repair, and improvement of alternative energy generation systems and associated equipment from the customer’s meter. AES does not authorize electrical work on its own, which surprises a lot of installers who assume one specialty covers the whole scope.

A firm performing the electrical portion of a solar job also needs the Electrical contractor classification, abbreviated ELE, plus properly licensed journeyman or master electricians doing or supervising that work. A contractor offering turnkey installation may need both AES and ELE authority, along with appropriately licensed electrical tradespeople, depending on how much of the scope it performs directly versus subcontracts out.

A Virginia solar contracting business needs the appropriate Class A, B, or C license plus the classification or specialty covering its work. The Alternative Energy System specialty, AES, covers defined solar system work but excludes electrical scope. Contractors handling the electrical portion of a job also need the Electrical classification and appropriately licensed electricians on staff.

A complete plan set is what turns a fast local review into a slow one, so getting the format right matters as much as getting the numbers right.

A Virginia solar permit plan set typically includes a site plan, array layout, structural attachment details, site specific wind criteria, an electrical one line diagram, service and point of interconnection details, conductor and overcurrent calculations, rapid shutdown documentation, labels, equipment specifications, and any required PE stamped or ESS documentation.

A complete Virginia plan set generally needs to document the following, though local AHJs can add their own project specific requirements on top of this baseline.

• Cover sheet with project scope and applicable code editions

• Site plan and property information

• Roof or ground mount layout with dimensions

• Wind speed, exposure category, and risk category for the site

• Structural attachment details for the specific racking product

• Roof framing or foundation details as applicable

• Electrical one line diagram

• Existing and proposed service equipment details

• Point of interconnection information

• Conductor and overcurrent protection device sizing

• Rapid shutdown design and compliant labeling

• Grounding and bonding details

• Equipment specifications and listings

• Energy storage system location, capacity, and clearances where applicable

• PE stamped calculations when the AHJ requires them

Keep the module count, inverter model, storage capacity, and point of interconnection identical across the permit drawings, equipment specs, and utility interconnection application. Mismatches between those documents are one of the most common reasons a project stalls in review.

Most single family rooftop jobs move through standard USBC review unless the locality has adopted SolarAPP+ or the statewide platform. Structural review typically focuses on roof attachment and wind load, while electrical review checks the one line diagram against the 2020 NEC.

Light commercial systems more often trigger three phase service considerations, larger conductor and OCPD calculations, and fire department coordination that a residential job rarely sees. PE stamped structural documentation is common on these projects even where a residential system might qualify for a simplified path.

Battery storage can add equipment listing, capacity, location, spacing, fire resistance, disconnect, signage, and emergency control documentation under the USBC, NEC, applicable fire code provisions, NFPA 855, and manufacturer instructions. Confirm early whether the local AHJ wants a standalone ESS permit or accepts combined submission with the solar electrical permit, since practice varies by locality.

The USBC applies one statewide wind chapter drawn from the referenced ASCE 7 edition, but the design wind speed used on a given project depends entirely on where the site sits. Coastal location can raise the basic wind speed, shift the exposure category, and trigger wind borne debris provisions that an inland site never has to think about.

Exposure category depends on actual upstream terrain rather than a simple coastal versus inland label, so two sites a short distance apart can land in different exposure categories. Racking certifications have to cover the calculated design pressures for the specific site, and PE stamped structural calculations become necessary once a project falls outside prescriptive or product engineering limits. Virginia Beach, Norfolk, Chesapeake, Hampton, Newport News, Portsmouth, and the Eastern Shore counties all carry coastal design considerations worth flagging early in a proposal.

Often, yes, though there is no single blanket coastal Virginia rule to apply. The designer needs the wind speed, exposure category, risk category, and wind borne debris provisions that apply to the specific site under the adopted USBC and ASCE 7 standard. Coastal sites can produce higher design pressures depending on basic wind speed, exposure category, building height, roof zone, and surrounding terrain, and that can trigger project specific structural documentation that would not be required further inland.

It depends on the jurisdiction and the project. Many AHJs accept manufacturer engineering letters and prescriptive racking guidance for straightforward residential systems. Larger arrays, unusual framing, coastal wind conditions, ground mounts, carports, and light commercial projects are more likely to fall outside that prescriptive or manufacturer engineered pathway and into PE stamped territory.

Virginia splits interconnection into two frameworks depending on what kind of project is going in. Net metered customer generators generally fall under 20VAC5-315, while broader small generator interconnections, including projects outside the net metering definition, fall under 20VAC5-314. The correct path depends on utility, project capacity, customer program, and export configuration, so confirm which regulation actually governs a given job before building the application.

Most residential and small commercial PV projects seeking net metering credit interconnect under 20VAC5-315. Larger generating facilities, non-net-metered projects, and certain agricultural generators may instead fall under the small generator interconnection framework in 20VAC5-314, which sets tiered review levels similar in spirit to other states’ fast track processes.

The serving electric utility reviews the actual grid connection. Most Virginia projects go through Dominion Energy, Appalachian Power, an electric cooperative, or a municipal utility, and the correct application and net metering rules depend on the service address, system size, customer class, and export configuration.

Dominion reviews net metered residential and light commercial projects under Virginia’s net metering rules and its own current tariff and application procedures. Dominion covers most of the state’s population, including Richmond, Hampton Roads, and Northern Virginia. Qualifying smaller inverter based systems may follow a streamlined or expedited application path, while larger or technically complex projects require additional distribution review, so confirm current application thresholds and fees directly with Dominion before quoting a timeline.

Appalachian Power, also called APCo, serves western and southwestern Virginia under the same state interconnection regulations that apply to Dominion. APCo residential customers are not subject to the net metering standby charge that applies in Dominion territory, which is worth mentioning to customers comparing notes with friends on the other side of the state.

Cooperative customers should work from the serving co-op’s current tariff, application, and engineering requirements rather than assuming a Dominion or APCo process applies. State statutes and regulations establish part of the framework, but individual cooperative procedures and technical screens can still differ from utility to utility, and co-op residential systems carry a lower capacity cap than IOU customers.

A handful of Virginia localities run their own municipal electric systems outside the standard investor owned utility structure. Confirm net metering and interconnection rules directly with the municipal provider, since these programs are not always built around the same regulatory framework that governs Dominion and APCo.

Working across multiple Virginia utility territories on the same pipeline? GreenLancer’s interconnection application service can handle the Dominion, APCo, or cooperative paperwork in parallel with the local permit so neither process stalls out waiting on the other.

Virginia net metering law lives in Code of Virginia section 56-594, and it is more specific than a lot of installers expect once you get past the headline numbers.

An eligible customer generator is capped at 25 kW for residential customers and 3 MW, or 3,000 kW, for nonresidential customers, but that is the ceiling for Dominion and Appalachian Power customers specifically. Electric cooperative customers work under a lower cap, generally 20 kW residential and 1 MW nonresidential. Eligible agricultural customer generators carry a separate per customer generating capacity limit of 500 kW under the same statute, which is distinct from the utilitywide aggregate program cap described below.

The nameplate ceiling is not the only sizing limit worth knowing. For systems installed after July 1, 2020, Appalachian Power territory generally caps a net metered system at 100 percent of the customer’s expected annual energy consumption, while Dominion territory allows up to 150 percent. The utility calculates expected consumption from billing history, or an annualized estimate when a full year of history is not available, so oversizing a system for future EV charging or electrification needs more than the nameplate cap.

For Dominion and Appalachian Power, the statutory aggregate net metering cap is generally 6 percent of the utility’s adjusted prior year peak load forecast, split so that 5 points are open to all customers and 1 point is reserved specifically for low income utility customers. Electric cooperatives use a different cap structure under 20VAC5-315, generally divided among residential, nonprofit or nonjurisdictional, and other nonresidential customer categories rather than one blended percentage. Check the serving cooperative’s published cap status before submitting an application near a program limit.

Residential and eligible agricultural customer generators in Dominion’s territory with a system exceeding 20 kW AC may be subject to a monthly standby charge, calculated using a methodology the utility develops and the SCC approves. That 20 kW AC threshold appears in both the currently effective version of Code of Virginia section 56-594 and the version taking effect January 1, 2027, so it is not a figure that is about to change on that date, though other provisions of the statute do shift at that time. Customers are not liable for the charge until the SCC approves the supplier’s methodology and specifies when it applies, so confirm the current Dominion tariff before presenting this cost to a customer. Appalachian Power residential customers have not faced this particular net metering standby charge since a July 1, 2020 prohibition took effect.

Dominion filed a significant net metering program proposal for review in 2025 and 2026, and solar advocacy groups and industry press covering the case reported that state regulators rejected several of the utility’s more aggressive proposed changes, including a shift to very short netting intervals and a claim on customer renewable energy certificates. Confirm the current effective tariff, netting interval, and compensation formula directly with Dominion or the State Corporation Commission before finalizing project economics for a customer, since the exact terms of any final order matter more than secondhand summaries.

Homeowners associations come up constantly on residential jobs, and Virginia law gives installers a real answer to point to. Under Code of Virginia section 55.1-1820.1, an association cannot prohibit an owner from installing a solar energy collection device on individually owned property unless the recorded declaration itself establishes that prohibition. Associations can still set reasonable restrictions on size, place, and manner of placement.

A restriction crosses into unreasonable territory if it raises installation cost by more than 5 percent or cuts projected energy production by more than 10 percent compared to the original proposed design. Backing that claim up requires documentation from an independent solar design specialist who is NABCEP certified and licensed in Virginia. A building permit and an HOA approval are two separate things, and one does not override the other, so both need to be squared away before installation starts.

Not outright, unless the recorded declaration specifically prohibits solar. Associations can impose reasonable restrictions on size, placement, and manner of installation, and a restriction is considered unreasonable once it increases cost by more than 5 percent or reduces expected production by more than 10 percent.

Virginia enacted new provisions addressing small portable solar generation devices, sometimes called plug-in or balcony solar, alongside its 2026 solar legislation package. These provisions take effect January 1, 2027 and address small plug-in systems along with certain tenant rights.

Plug-in products differ meaningfully from a conventional permanently installed rooftop system and will not follow the same plan set or interconnection workflow described in this guide, so treat this as a heads up for a future product category rather than a 2026 permitting requirement.

Check each of these before submitting a Virginia project.

• Wrong locality or permit portal used for the address

• Incorrect 2021 USBC or 2020 NEC citation on the drawings

• Building and electrical scopes submitted inconsistently with each other

• Incorrect basic wind speed, exposure category, or risk category for the site

• Racking engineering that does not cover the calculated wind pressures

• PE stamp missing or from an engineer not licensed in Virginia

• Contractor class or specialty that does not cover the proposed scope

• SolarAPP+ assumed available for an ineligible system or locality

• Permit and utility documents showing mismatched equipment or capacities

• Dominion’s 20 kW AC standby charge threshold overlooked during sizing

• HOA approval treated as a substitute for the building permit, or the reverse

• ESS listing, capacity, location, or clearance documentation left incomplete

• Utility territory or customer program selected incorrectly on the application

A few Virginia localities are worth flagging by name, either because they already run automated permitting or because they represent high installer volume worth building a dedicated process around.

Prince William County offers SolarAPP+ for qualifying residential projects and sits within Dominion territory for most addresses. Confirm whether a separate county inspection step applies even after automated plan approval.

Fairfax County and the broader Northern Virginia market represent some of the highest installer volume in the state, even without early SolarAPP+ adoption. Confirm the current local permit portal, inspection sequence, and Dominion service details for the specific address, since neighboring Northern Virginia jurisdictions do not automatically share the same workflow even though they enforce the same statewide USBC.

Harrisonburg was among the first Virginia localities to adopt SolarAPP+ and runs its own LAMA permitting portal alongside it. Verify how the SolarAPP+ approval connects to the city’s broader permit process before submitting.

Virginia Beach sits at the higher end of Virginia’s coastal wind speed range and adds wind borne debris considerations for sites close to open water, on top of its own local building permit process within Dominion territory. Racking certifications and any required PE stamped calculations should be based on the city’s own site data rather than a regional estimate pulled from a neighboring locality.

Norfolk, Chesapeake, Hampton, Newport News, and Portsmouth each administer their own permitting separately from Virginia Beach and from each other, even though the whole Hampton Roads region shares coastal wind design concerns. Do not assume one locality’s process, wind speed data, or exposure category applies to a neighboring city.

Culpeper County participates in SolarAPP+ and represents a more rural, mixed utility territory compared to the Dominion heavy Northern Virginia corridor. Confirm eligible system types before assuming automated review applies.

Pulaski County is a SolarAPP+ participant in the southwestern part of the state, generally within Appalachian Power territory. Verify current building and electrical submission requirements directly with the county before finalizing a plan set.

• Confirm the local building department and whether it enforces the USBC directly or through a regional authority

• Verify whether the locality uses SolarAPP+ or the statewide Smart Solar Permitting Platform yet

• Confirm the contractor’s Class A, B, or C license and classification cover the proposed scope

• Pull the site specific wind speed, exposure category, and risk category before finalizing racking design

• Identify the correct interconnection framework, either 20VAC5-315 or 20VAC5-314, for the project type

• Confirm the serving utility’s net metering cap and any applicable standby charge threshold

• Check the recorded HOA declaration for any solar specific restriction before design is finalized

• Keep module count, inverter model, and point of interconnection consistent across all submitted documents

Virginia’s mix of one statewide code, utility specific interconnection, and coastal wind variation makes it a state where getting the details right the first time really pays off. GreenLancer’s solar engineering service connects installers with licensed structural and electrical engineers who can build wind rated calculations sized to the correct site data, coastal or inland.

Complete the form below to get started.

The local building department issues and enforces both the building and electrical permits under the USBC. Most permanent rooftop and ground mounted PV projects need approval on both scopes.

Yes. The USBC applies across the Commonwealth and is enforced locally. The current cycle, effective since January 18, 2024, is based on the 2021 I-Codes with the 2020 NEC, though procedures and documentation still vary by AHJ.

Not yet everywhere. The 2026 law requires localities to accept the state platform or an approved alternative by January 1, 2028. Confirm current locality participation rather than assuming statewide availability in 2026.

The appropriate Class A, B, or C license plus the classification or specialty covering the work it contracts to perform. The Alternative Energy System specialty, AES, covers defined solar system work but excludes electrical scope, so electrical contracting requires the separate Electrical classification and appropriately licensed electricians.

A site plan, array layout, structural attachment details, site specific wind criteria, an electrical one line diagram, interconnection details, rapid shutdown documentation, equipment specs, and PE stamped or ESS documentation when required.

Dominion and Appalachian Power customers are capped at 25 kilowatts. Electric cooperative residential systems are generally limited to 20 kilowatts. Consumption based sizing rules and standby charges can further limit the final design.

Both investor owned utilities generally allow residential systems up to 25 kilowatts, but consumption based sizing differs. Appalachian Power generally limits a system to 100 percent of expected annual use, while Dominion generally allows up to 150 percent, subject to current tariffs and interconnection requirements.

No. Cooperative residential systems are generally limited to 20 kilowatts and nonresidential systems to 1 megawatt under current regulations. Individual co-op tariffs, technical screens, export rules, and available program capacity can still vary from one cooperative to the next.

Residential and eligible agricultural customer generators in Dominion territory with a system exceeding 20 kilowatts AC may be subject to an SCC approved monthly standby charge. Appalachian Power customers have not faced this charge since July 1, 2020.

Virginia has no single statewide PE stamp threshold. The local AHJ decides whether manufacturer engineering and prescriptive guidance are enough or whether sealed structural documentation is required, and coastal wind exposure makes that more likely.

An association cannot prohibit solar panels on individually owned property unless its recorded declaration establishes that prohibition. Restrictions are unreasonable if they raise installation cost by more than 5 percent or cut expected production by more than 10 percent.
