A building permit in Middletown is issued by the town’s own Permits, Licensing and Inspections Department, which enforces the International Building Code and the Code of the Town of Middletown and inspects each phase before a certificate of occupancy — so inside the town the permit is a town matter, and New Castle County does not issue here.
Middletown's distinctive requirement is a town contractor licence set by ordinance. No one may carry on building, alteration, repair, remodelling or construction in the town without first obtaining a licence from the town's permit officer, and the application must be verified by oath or affirmation that the applicant is knowledgeable of and complies with the town's building, plumbing, mechanical, fire prevention and zoning codes — a step distinct from the state business licence.
This guide covers the town of Middletown, in New Castle County. Work outside the town limits falls to New Castle County or another municipality; confirm the address is inside the town before you file with Licensing and Inspections.
The town contractor licence comes before the work, not the permit counter. Because Middletown requires a town contractor licence by ordinance — applied for under oath — a contractor new to the town should obtain it well before the job needs to start, since the town checks it as part of issuing and inspecting the work.
What requires a building permit in Middletown?
Delaware has no statewide building code. Each county, and each town that runs its own building department, adopts and enforces its own, and the editions, amendments and effective dates differ between them — so a rule that applies in one part of Delaware may simply not apply 30 minutes away. New Castle County administers its code through the Department of Land Use, Kent County through its Department of Planning Services (Division of Inspection and Enforcement), and Sussex County through its Building Permit Office and Building Code Office, which also cover a number of incorporated towns that have not taken the function on themselves. Above them sit statewide rules: plumbing, mechanical, fuel gas, energy and fire codes set at state level, electrical inspection by a state-licensed agency, and the State Fire Marshal's plan review. So in Middletown the questions are which authority holds the building code, which edition it is on, and whether every contractor on the job holds the Town of Middletown's own contractor licence, which the town code requires before any work begins.

Which authority holds the code for your address
Middletown runs its own Licensing and Inspections Department and enforces the International Building Code together with the Code of the Town of Middletown — and it requires, by ordinance, that any contractor doing building or reconstruction work first obtain a Town of Middletown contractor licence, applied for under an oath that the applicant has complied and will comply with the town's building, plumbing, mechanical, fire prevention and zoning codes.
Delaware has no statewide building code — each county and town that runs a building department adopts its own — but plumbing, mechanical, fuel gas, energy and fire codes are set at state level, electrical work is inspected by state-licensed agencies, and the State Fire Marshal reviews plans for most non-residential work.

Permit types
Residential permits
Houses, additions, decks, patios, garages, sheds, swimming pools and alterations inside the town are permitted through Permits, Licensing and Inspections, and since 2 June 2025 the town’s residential work is built to the 2024 International Residential Code with town amendments, together with the Code of the Town of Middletown. A non-occupant owner who rents a dwelling must have the property inspected and registered before occupancy.
Commercial permits
Commercial and multi-family work is reviewed under the International Building Code the town enforces, and because Middletown is not one of Delaware's jurisdictional city fire marshals, the State Fire Marshal carries out the fire plan review alongside the town permit. Every contractor on the job must hold the town's own contractor licence first.
The state reviews that run alongside the permit
In Middletown the State Fire Marshal carries out the fire plan review, since the town is not one of Delaware's jurisdictional city fire marshals, and all electrical work is regulated at state level through the Board of Electrical Examiners.
Delaware has no general contractor licence: contractors need a state contractor business licence and Department of Labor registration, and electricians, plumbers, HVACR and fire protection contractors are licensed by the state. Delaware rules
Middletown permit costs and fees
Middletown charges the building permit on the valuation of the work — $12 per $1,000 — with separate plan-review and inspection fees set in the town’s fee sheets. The cost item particular to the town is the town contractor licence, an ordinance credential each contractor must hold in addition to the state business licence.

Call 1-855-478-4290 →| Item | Fee or rule |
|---|---|
| Building permit | $12 per $1,000 of valuation (commercial: $12 per $1,000 up to $1,000,000, then $3 per $1,000), plus plan-review and inspection fees |
| Town contractor licence | An ordinance credential for building or reconstruction work, applied for under oath, on top of the state business licence |
| Rental registration | Registration and a pre-occupancy inspection for a non-occupant owner's rental |
| Where it is paid | Through the Licensing and Inspections Department at Town Hall |
The town contractor licence is separate from the state business licence. Every contractor doing building or reconstruction work in Middletown needs the town's own contractor licence in addition to the state business licence, so a contractor new to the town should treat it as a first cost rather than a permit-counter afterthought.

County in unincorporated areas, the municipality where it runs a building department, and in some towns the county for building with the town for zoning.
The three counties are on different editions with different effective dates and amendments.
Required on new buildings, additions, changes of occupancy and fire damage, except two-family dwellings and farm buildings, and on sprinkler, alarm and fuel installations and tenant fit-outs.
Sediment and stormwater approval from the delegated agency (conservation district, county or city), and DNREC wetlands or beach approvals where the site needs them.
Many permit offices ask for the Delaware contractor business licence, contractors must be registered with the Department of Labor, and some municipalities require their own licence.
Footing to final with the authority, electrical through a licensed inspection agency, then the certificate of occupancy.
Review, corrections and what actually causes delay
The Middletown delays that recur are licence delays: a contractor who has not yet obtained the town contractor licence, or a rental brought into service without its registration and pre-occupancy inspection. Clearing the town contractor licence before the permit application, and settling any rental registration separately, keeps the Licensing and Inspections review on track.
Inspections in Middletown
Inspections follow the sequence in whichever code edition the authority has adopted — footing, foundation, framing, rough trades, insulation and final — requested from the county or the municipality against the permit number. Electrical inspections are the exception: they are carried out by licensed electrical inspection agencies, and their approval documentation is what the permitting authority and the State Fire Marshal rely on. A certificate of occupancy closes the file, and where the fire marshal reviewed the plans its own approval is a precondition of that certificate. In Middletown the inspections run through Licensing and Inspections against the permit number — a request confirmed by mid-afternoon is scheduled for the next day, within a set arrival window — and where the State Fire Marshal reviewed the plans its approval is a precondition of the certificate of occupancy.

Frequently asked questions
Does the town or New Castle County issue my permit?
Inside the town of Middletown, the Licensing and Inspections Department issues the permit and New Castle County does not. The town enforces the International Building Code and its own town code.
Do contractors need a town licence?
Yes. The town code requires any contractor doing building or reconstruction work to obtain a Town of Middletown contractor licence first, applied for under an oath that the applicant complies with the town's building, plumbing, mechanical, fire prevention and zoning codes. It is separate from the state business licence.
Inspections are where schedules slip.
Get a free quote →Who reviews my plans for fire?
Middletown is not one of Delaware's jurisdictional city fire marshals, so the State Fire Marshal carries out the fire plan review on new buildings, additions, changes of occupancy and fire-damaged work, alongside the town permit.
Which residential code does the town build to?
The town adopted new codes on 2 June 2025: the 2024 International Residential Code with town amendments, the 2024 International Mechanical, Existing Building and Fuel Gas Codes, the 2021 International Plumbing Code with amendments and the 2018 International Energy Conservation Code, together with the Code of the Town of Middletown. Confirm any town amendment with Permits, Licensing and Inspections before you design to it.
Is electrical work inspected by the town?
No. Electrical work is regulated at state level through the Board of Electrical Examiners and inspected by a licensed electrical inspection agency rather than the town, and that agency's approval is relied on at closeout.
How do I schedule an inspection?
Inspections are requested from Licensing and Inspections against the permit number. A request confirmed by mid-afternoon is scheduled for the next day within a set arrival window, so build the sequence into the job's timing.
