A building permit in Newark is issued by the city's own Code Enforcement Division, part of the Planning and Development Department, which reviews the work, issues the permit and inspects it — so inside the city the permit is a city matter, and New Castle County does not issue here.
Newark's distinctive rules come from the university. An annual rental permit is required for every non-owner-occupied single-family or two-family dwelling, and for every owner-occupied dwelling taking in more than two unrelated roomers. A student home carries a further limit: it is permitted on a lot only if no part of the lot is closer to another student home than 10 times the required lot width for a single-family detached dwelling in that zoning district, and a permitted student home may be occupied by no more than three persons.
This guide covers the city of Newark, in New Castle County. Work outside the city limits falls to New Castle County or another municipality; confirm the address is inside the city before you file with Code Enforcement.
A rental permit and the student-home spacing rule are separate from the building permit. If the project is a rental or a student home, the annual rental permit and the student-home dispersal and occupancy limits apply on top of any building permit — and the spacing test can decide whether a student home is allowed on the lot at all, so it belongs at the front of the plan, not the end.
What requires a building permit in Newark?
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 Newark the questions are which authority holds the building code, which edition it is on, and whether the property is a rental or a student home, which Newark permits and disperses under rules built around the university.

Which authority holds the code for your address
Newark runs its own Code Enforcement Division within the Planning and Development Department and, as one of Delaware's jurisdictional city fire marshals, its own fire marshal's review — and because it is a university city it layers on a rental and student-home regime: every non-owner-occupied dwelling needs an annual rental permit, and a student home is allowed on a lot only where it sits far enough from the next one.
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, alterations, decks and demolition inside the city are permitted through Code Enforcement. Rentals carry a separate obligation: every non-owner-occupied dwelling, and every owner-occupied dwelling taking in more than two unrelated roomers, needs an annual rental permit with an annual inspection, and student homes are limited both in where they may sit and in how many people may occupy them.
Commercial permits
Commercial and multi-family work is reviewed under the city's codes, and the city fire marshal — not the state office — carries out the fire plan review, because Newark is one of Delaware's jurisdictional city fire marshals. New or rezoned buildings complete the city's fire review alongside the building permit.
The state reviews that run alongside the permit
In Newark the city operates its own jurisdictional fire marshal, so the plan review the State Fire Marshal performs in most of Delaware is carried out by the city.
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
Newark permit costs and fees
Newark charges its building permit on construction value under the city’s fee schedule: $15 per $1,000 up to $1,000,000 and $8 per $1,000 above that, with a $50 minimum, plus a plan review fee and a technology fee of 15% of the permit fee. The recurring cost particular to the city is the annual rental permit, which is not a one-time permit at all but a yearly licence with a yearly inspection.

|---|---|
| Building permit | $15 per $1,000 of construction value up to $1,000,000, then $8 per $1,000 ($50 minimum); plan review $1 per $1,000 ($25 minimum, $5,000 maximum); technology fee 15% of the permit fee (up to $4,000) |
| Rental permit | An annual permit with an annual inspection for non-owner-occupied and qualifying owner-occupied dwellings; $234 a unit for single-family and two-family dwellings in 2026 |
| Fire plan review | Charged by the city fire marshal on new or rezoned buildings and the work the fire code reaches |
| Where it is paid | Through the Code Enforcement Division on South Main Street |
The rental permit is a recurring licence, not a one-time fee. A rental in Newark carries an annual rental permit and an annual inspection for as long as it is let, an ongoing cost that sits outside the one-time building permit and applies whether or not any construction is planned.

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 Newark delays that recur are not about the drawings — they are about the rental and student-home rules. A rental brought into service without its permit and inspection, or a student home that fails the 10-times-lot-width spacing test, will stop a project regardless of how sound the construction plans are. Settling the rental permit and testing the student-home spacing before anything else keeps the Code Enforcement review moving.
Inspections in Newark
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 Newark the inspections run through Code Enforcement against the permit number, the city fire marshal's approval is a precondition where its plan review applied, and rental properties carry their own annual inspection separate from construction inspections.

Frequently asked questions
Does the city or New Castle County issue my permit?
Inside the city of Newark, the Code Enforcement Division issues the permit and New Castle County does not. The city runs its own code enforcement and its own fire marshal, so the process stays with the city.
Do I need a rental permit?
Every non-owner-occupied single-family or two-family dwelling needs an annual rental permit, as does every owner-occupied dwelling taking in more than two unrelated roomers. The permit carries an annual inspection and must be renewed each year.
Inspections are where schedules slip.
Get a free quote →What is the student-home rule?
On a non-exempt street, a student home is permitted on a lot only if no part of the lot is closer to another student home than 10 times the required lot width for a single-family detached dwelling in that zoning district, and a permitted student home may be occupied by no more than three persons. The spacing test can decide whether a student home is allowed at all.
Who reviews my plans for fire?
Newark is one of Delaware's jurisdictional city fire marshals, so its own fire marshal carries out the plan review that the State Fire Marshal performs in most of the state. New or rezoned buildings complete that review alongside the building permit.
Which authority holds the code inside the city?
The city of Newark enforces its own codes through Code Enforcement, separate from New Castle County. It has adopted the 2018 International Building, Existing Building, Energy Conservation, Residential, Plumbing, Mechanical, Fuel Gas and Fire Codes and the Delaware State Fire Prevention Code, and a city amendment requires an approved fire suppression system in every new building, residential and commercial.
Is electrical work inspected by the city?
No. Electrical work in Newark is regulated at state level and inspected by a licensed electrical inspection agency rather than the city, and that agency's approval is what the city relies on at closeout.
