Electrical Permit Guide for Delaware 2026
Permit costs, processing times, NEC edition, licensing authority, and the rules that are actually enforced in Delaware.
Quick Facts: Delaware Electrical Permits
Typical Permit Cost
Delaware does not run a city/county-issued electrical permit system in the traditional sense. The state-level "permit" pieces are the Division of Professional Regulation (DPR) homeowner permit at $42 (24 DAC 1400-14) and contractor licensing fees through DELPROS. The cost a homeowner actually pays is dominated by the licensed third-party inspection agency they hire under 24 DAC 1400-12 and 1400-15. Typical residential service-change/panel-upgrade inspection runs roughly $150–$300; whole-house rough-in plus final commonly $250–$600; new-construction single-family $400–$900 across rough, service, and final; pool/hot-tub bonding inspections $175–$350; EV charger circuit inspections $125–$225; commercial work is fee-quoted by each inspection agency. Plan review/stamping by the inspection agency (required before a homeowner permit is filed) is typically $75–$200. New Castle County, Kent County, and Sussex County do not collect a separate electrical permit fee — they verify the state inspection certificate at building-permit closeout.
Processing Time
DPR homeowner permits issue same-day to 1–2 business days through DELPROS once plans are stamped by an approved inspection agency. Inspection agencies are required by 24 DAC 1400-12.3 to perform the requested inspection within 5 working days of the application; the licensed electrician must file that application within 5 working days of starting work. Most agencies (MDIA, American Inspection Agency, First State, Eagle, United, Bay Area, Building Inspection Underwriters, Code Solutions International) respond next-day for service calls and within 24–72 hours for rough-ins. Sussex County summer-season hot-tub and pool work occasionally pushes scheduling out 5 full days due to volume.
Online Portal Availability
Partial. License applications, renewals, license verification, and homeowner permits run through DELPROS at delpros.delaware.gov. License lookups are at delpros.delaware.gov/OH_VerifyLicense. Inspection scheduling, however, is NOT centralized: each licensed inspection agency books its own work directly (phone, email, or that agency portal). New Castle County uses inspections.newcastlede.gov for building permits but explicitly defers electrical inspections to the state-licensed agencies. Kent County uses MyGovernmentOnline.org for building permits with the inspection agency certificate uploaded as a closeout document. Sussex County uses an in-person/online hybrid through sussexcountyde.gov.
Inspections
Typically 2–3 third-party inspections for a standard residential job: a rough-in/concealment inspection before drywall, a service inspection before Delmarva Power (or DEMEC muni) energizes, and a final. Service-only swaps (100A-to-200A panel upgrade) often combine into one rough/final visit. Homeowner-permit work under 24 DAC 1400-14 requires plan pre-approval (stamped by the inspection agency before the permit is even filed), then an initial inspection within 5 working days of starting work, then a rough-in before drywall, then a final.
Delaware Electrical Licensing
Delaware Division of Professional Regulation (DPR), Board of Electrical Examiners — Cannon Building, 861 Silver Lake Blvd., Suite 203, Dover, DE 19904 / (302) 744-4500 / customerservice.dpr@delaware.gov
Delaware licenses seven electrician categories under 24 Del. C. § 1408 and 24 DAC 1400: Master Electrician ($203 application), Master Electrician Special / specialty work like elevators or HVAC ($200), Limited Electrician / residential and light commercial ($127), Limited Electrician Special ($127), Journeyperson Electrician ($105), Residential Electrician ($105), and Apprentice Electrician ($79). Homeowner Permits are $42 and Inspection Agency licensing is $90 (renewed annually each June 30). Master applicants need 6 years of full-time experience under a licensed master, OR 8,000 hours plus 576 hours of related instruction in a Board-approved apprenticeship, OR 4 years of experience plus 2 years of technical training, plus passing the Master exam. Limited applicants need 3 years of experience or 4,000 hours plus 288 hours of instruction. All licensees must carry general liability insurance and renew biennially with continuing-education hours per 24 DAC 1400-8. Effective July 1, 2026 (Senate Bill 102), apprentice licenses cap at 5 years total — apprentices already licensed 5+ years at that date are grandfathered. Reciprocity under 24 DAC 1400-11 is granted where another state standards are "substantially similar"; Delaware has full reciprocity for Master Electrician with Michigan and Wyoming, and case-by-case reciprocity with Arkansas, Colorado, DC, Florida, Georgia, Maine, Massachusetts, Nebraska, Nevada, New Hampshire, North Carolina, Ohio, Texas, Vermont, Virginia, and West Virginia.
Electrical Code in Delaware
24 DAC 1400 (Board of Electrical Examiners) + Delaware State Fire Prevention Regulations (NEC adoption) — Current Edition
2023 NEC (NFPA 70-2023), effective January 1, 2026 statewide
Delaware NEC adoption authority is unusual: under 24 DAC 1400-1.0, "the version of the NEC applicable to a particular project is determined by the Delaware State Fire Prevention Commission" — not the licensing board, not the counties. The Fire Prevention Commission voted in October 2025 to adopt the 2023 NEC effective January 1, 2026, replacing the 2020 NEC that had been in force since 2021. Any permits issued, projects started, or inspection applications received on or after January 1, 2026 are governed by the 2023 NEC. Statutory authority flows from 24 Del. C. Chapter 14 (Board of Electrical Examiners) for licensing and inspection-agency oversight, and from 16 Del. C. Chapter 66 (State Fire Prevention) for the substantive code. Delaware does not amend the NEC heavily — adoption is by reference rather than line-edited like California or New York.
When Do You Need an Electrical Permit in Delaware?
Delaware permit model is unlike almost every other state. Counties and most cities do not issue electrical permits or perform electrical inspections at all — that work is delegated by statute (24 Del. C. § 1408 and 24 DAC 1400-12, -15) to a small group of state-licensed third-party inspection agencies. The big eight in 2026 are American Inspection Agency, Bay Area Inspection Agency, Building Inspection Underwriters, Code Solutions International, Eagle Inspection Agency, First State Inspection Agency, Middle Department Inspection Agency (MDIA), and United Inspection Agency. A licensed Delaware electrician must file an inspection request within 5 working days of starting work; the agency then has 5 working days to inspect. Owner-occupants of single-family dwellings can pull a $42 DPR homeowner permit, but plans must be pre-approved and stamped by an approved inspection agency before the permit can even be filed, and pool/hot-tub work is excluded from the homeowner exemption. Electrical work in Delaware is judged against the 2023 NEC (effective January 1, 2026) as adopted by the State Fire Prevention Commission and any applicable local building code.
Permit Required
- New service entrances, panel changes, meter relocations, and ampacity upgrades (100A, 150A, 200A, 320A, 400A) — inspection by a licensed inspection agency required before Delmarva Power or DEMEC muni energizes
- New branch circuits, feeders, and rewiring (kitchen, bath, laundry, additions) — 24 DAC 1400-12 inspection within 5 working days of work commencement
- EV charger circuits and Level 2 EVSE (40A and 60A dedicated circuits) — 2023 NEC Article 625
- Solar PV interconnections, battery energy storage systems, and grid-tied wind systems — required before Delmarva Power closes interconnection under 26 Del. C. § 1014 net metering
- Generator transfer switches, interlocks, and standby/portable generator interconnections
- Heat pump and electric water heater dedicated circuits
- Hot tub, pool, spa, and equipotential bonding wiring (NEC Article 680) — explicitly excluded from the homeowner-permit scope and must be performed by a licensed electrician
- Mobile home and manufactured-home service installations (24 DAC 1400-12 special provisions)
- Commercial, industrial, and agricultural electrical work (agricultural inspection has its own subsection in 24 DAC 1400-12)
- Fire alarm system wiring (24 DAC 1400-12.10) — separate inspection workflow
Typically Exempt
- Like-for-like replacement of switches, receptacles, and luminaires on existing branch circuits where no new wiring is added
- Repair or replacement of cord-and-plug appliances on existing approved circuits
- Public utility company work on its own equipment up to and including the meter (Delmarva Power, DEMEC munis, DEC)
- Low-voltage doorbell, thermostat, and irrigation control wiring (verify with the chosen inspection agency)
- Owner-occupant repair work in a single-family dwelling that does not require new circuits or service alteration (24 DAC 1400-10 exceptions; pool/hot-tub work is NOT exempt)
Exempt from permit does not mean exempt from the code. Work still must comply with the edition in force at your address.
Delaware-Specific Rules You Should Know
Counties and cities do not issue electrical permits — third-party agencies do
Delaware delegates electrical inspection statewide to private inspection agencies licensed by the Board of Electrical Examiners under 24 DAC 1400-15. New Castle County own permits page states plainly that "the County does not permit or inspect electrical work." Kent County requires a Delaware-recognized electrical inspection agency certificate before closing out a building permit. Sussex County operates the same way. Even the City of Wilmington defers electrical inspection to the state-licensed agencies. Out-of-state contractors expecting a county "electrical permit" line item find none — they choose an agency from the DPR licensed list, file directly, and pay that agency fee schedule. The county role is verifying the state inspection certificate at the end.
Nine licensed inspection agencies as of March 2025
Per the DPR March 3, 2025 list, the licensed inspection agencies are: American Inspection Agency (Newark + Dagsboro), Bay Area Inspection Agency (Middletown), Building Inspection Underwriters (Newark), Code Solutions International (Harbeson), Eagle Inspection Agency (Newark), First State Inspection Agency (Milford), Middle Department Inspection Agency / MDIA (Wilmington + Middletown + Millsboro), and United Inspection Agency (Wilmington). MDIA is the dominant statewide player and the historical Mid-Atlantic incumbent (descended from the 1883 Middle Department Association of Fire Underwriters). For Sussex County beach work, First State (Milford), Code Solutions (Harbeson), and American (Dagsboro) are the closest. Each agency sets its own fee schedule, so prices vary noticeably.
NEC version is set by the Fire Prevention Commission, not the licensing board
24 DAC 1400-1.0 explicitly states that "the version of the NEC applicable to a particular project is determined by the Delaware State Fire Prevention Commission." That commission voted in October 2025 to adopt the 2023 NEC effective January 1, 2026, replacing the 2020 NEC that had been in force since 2021. Any permit issued, project started, or inspection application received on or after January 1, 2026 is governed by the 2023 NEC — including the expanded GFCI/AFCI requirements, the 240V receptacle 2023 rule, and updated EV charger provisions in Article 625.
Homeowner permit requires pre-stamped plans and excludes pool/hot-tub
24 DAC 1400-14 lets owner-occupants of single-family dwellings pull their own electrical permit for $42 through DELPROS. Catch one: the plan must be reviewed, approved, and stamped by a Delaware-licensed inspection agency BEFORE you file the permit application. Catch two: hot-tub or swimming-pool work is explicitly excluded from the homeowner permit, and mobile homes on leased lots cannot include service-equipment installation. Catch three: condos, townhomes, multi-unit buildings, apartments, duplexes, and commercial property owners are not eligible — this is single-family-detached only. Two inspections are mandatory: an initial within 5 working days of starting work, and a rough-in before drywall.
Sussex County beach corridor concentrates pool, hot-tub, and EV-charger work
Lewes, Rehoboth, Bethany, Dewey, Fenwick, and the Inland Bays second-home market drive an outsized share of Delaware pool, hot-tub, and dedicated 60A EV charger volume. Hot tubs and pools fall outside the homeowner exemption (24 DAC 1400-14), so every install must go through a licensed Delaware electrician plus a licensed inspection agency. NEC Article 680 equipotential bonding for pools and Article 682 for natural and artificial bodies of water (Inland Bays piers, docks) get scrutinized closely. Coastal flood-zone homes also commonly need raised meters above base flood elevation per FEMA construction standards and Sussex County floodplain regulations — coordinate with the inspection agency before relocating service equipment.
Net metering is statewide at 25 kW residential, 2 MW non-residential
26 Del. C. § 1014 requires Delmarva Power, the Delaware Electric Cooperative (DEC), and all DEMEC municipal utilities to offer net metering. Residential cap is 25 kW; non-residential cap is 2 MW per meter. Excess kWh credits roll forward month-to-month at the full retail rate, and at the end of the annualized billing period excess credits are NOT cashed out — they are forfeited under 26 Del. C. § 1014(d)(2). The aggregate cap at which a utility may elect not to offer net metering was raised from 5% to 8% of system peak under SB 298 (2022). Solar PV interconnections also feed into the SRECDelaware procurement program administered by Delmarva Power; the solar alternative compliance payment is currently $400/MWh.
Five-business-day inspection clocks run both directions
24 DAC 1400-12.3 sets two parallel 5-working-day clocks: the licensed electrician must file an inspection application within 5 working days of starting work, and the inspection agency must perform the requested inspection within 5 working days of receiving the application. Miss either window and you have a Board-reportable defect that the agency must document within 15 days if the violation is uncorrected. Out-of-state contractors used to "schedule when ready" workflows get tripped by the front-side 5-day filing deadline.
Reciprocity is broad on paper, narrower in practice
Under 24 DAC 1400-11, Delaware grants Master Electrician reciprocity to Michigan and Wyoming outright. Case-by-case reciprocity is available with Arkansas, Colorado, DC, Florida, Georgia, Maine, Massachusetts, Nebraska, Nevada, New Hampshire, North Carolina, Ohio, Texas, Vermont, Virginia, and West Virginia — all conditional on the Board finding the originating state requirements "substantially similar." Reciprocity applicants must submit license verifications from every jurisdiction they have ever held a license, plus 5 years of licensed full-time experience under a licensed master. Notably absent: Maryland, Pennsylvania, and New Jersey have no formal reciprocity with Delaware despite being immediate neighbors — the Delmarva regional contractor must hold separate Delaware licensure.

Delaware Electrical Permit FAQs
Who issues electrical permits in Delaware?
There is no county or city electrical permit in Delaware. The state delegates inspection to private agencies licensed by the Board of Electrical Examiners under 24 DAC 1400-15. A licensed Delaware electrician files an inspection application directly with one of the licensed agencies (American Inspection Agency, MDIA, First State, Eagle, United, Building Inspection Underwriters, Bay Area, or Code Solutions International) within 5 working days of starting work. Homeowners pulling their own permit on owner-occupied single-family work file a $42 permit through DELPROS, but the plans must first be stamped by one of those licensed agencies.
Which NEC edition does Delaware enforce in 2026?
The 2023 NEC (NFPA 70-2023), adopted by the Delaware State Fire Prevention Commission effective January 1, 2026. Any permit issued, project started, or inspection application received on or after January 1, 2026 is judged against the 2023 NEC. From 2021 through December 31, 2025 Delaware was on the 2020 NEC. Per 24 DAC 1400-1.0, the Fire Prevention Commission — not the Board of Electrical Examiners — sets the applicable NEC edition.
Can a Delaware homeowner pull their own electrical permit?
Yes, on owner-occupied single-family detached homes only. Cost is $42 through DELPROS (24 DAC 1400-14). Three catches: (1) plans must be reviewed, approved, and stamped by a licensed Delaware inspection agency BEFORE filing; (2) hot tubs and swimming pools are excluded from the homeowner permit and must be done by a licensed electrician; (3) condos, townhomes, multi-unit, apartments, duplexes, and commercial properties are not eligible. Two mandatory inspections: initial within 5 working days of starting, and rough-in before drywall.
How much does a Delaware electrical inspection cost?
Inspection fees are set by each licensed agency, not by the state. Typical residential ranges: $150–$300 for a service/panel upgrade, $250–$600 for a whole-house rough plus final, $175–$350 for pool/hot-tub bonding, $125–$225 for an EV charger circuit. Plan review/stamping for homeowner permits is typically $75–$200 on top. The DPR homeowner permit itself is a flat $42. Counties and cities do not collect a separate electrical permit fee.
How do I become a licensed electrician in Delaware?
Register as an Apprentice with DPR through DELPROS ($79). Document the experience hours required by 24 Del. C. § 1408 — 4,000 hours plus 288 hours of instruction for Limited Electrician, or 8,000 hours plus 576 hours for Master, or alternative experience-only paths. Pass the Limited or Master exam (administered for the Board). Pay the initial fee ($203 Master, $127 Limited, $105 Journeyperson, $105 Residential), submit proof of general liability insurance, and renew biennially with continuing education per 24 DAC 1400-8. Apprentice licenses are capped at 5 years total effective July 1, 2026 under SB 102 (2025).
Does Delaware have reciprocity with neighboring states?
Surprisingly limited. Under 24 DAC 1400-11, Delaware grants outright Master Electrician reciprocity with Michigan and Wyoming, and case-by-case reciprocity with Arkansas, Colorado, DC, Florida, Georgia, Maine, Massachusetts, Nebraska, Nevada, New Hampshire, North Carolina, Ohio, Texas, Vermont, Virginia, and West Virginia. Notably, Maryland, Pennsylvania, and New Jersey — Delaware immediate neighbors — have no formal reciprocity. Delmarva regional contractors must hold a separate Delaware Master or Limited Electrician license.
How does Delaware net metering work for solar in 2026?
Per 26 Del. C. § 1014, Delmarva Power, Delaware Electric Cooperative, and all DEMEC municipal utilities must offer net metering for residential systems up to 25 kW and non-residential systems up to 2 MW per meter. Excess kWh credits roll forward month-to-month at the full retail rate, but at the end of the annualized billing period excess credits are NOT cashed out — they expire. The aggregate utility-level cap was raised from 5% to 8% of system peak under SB 298 (2022). Solar projects also feed Delmarva Power SRECDelaware procurement program (current SACP $400/MWh).
Do Sussex County beach towns have extra electrical permit rules?
No extra electrical permit fee — Lewes, Rehoboth, Bethany, Dewey, and Fenwick all defer to the state-licensed inspection agencies. The practical differences are FEMA flood-zone construction (raised meters and service equipment above base flood elevation), heavy NEC Article 680 pool/hot-tub bonding scrutiny on second-home installs, and high seasonal demand that can push inspection scheduling to the 5-working-day limit set by 24 DAC 1400-12.3. The closest agencies for Sussex coastal work are First State (Milford), American (Dagsboro), and Code Solutions International (Harbeson).
