Dover DE's Dual City/County Permit Sequencing
Out-of-town contractors showing up in Dover for their first Delaware state-capital project routinely submit permit applications directly to Kent County Levy Court and get bounced back. The reason is structural: Dover's permit process runs through two separate bodies — City of Dover Planning & Zoning first, then Kent County. Skipping the city step puts your application at the wrong desk. This essay walks the sequence and why it exists.
The structural split
Dover sits in Kent County, and Delaware's municipal-zoning authority is granted under state statute (8 Del. C. § 700 et seq.). In practice this means:
- The City of Dover Department of Planning and Zoning administers the Dover zoning code — use-by-right, variances, special exceptions, site plans, conditional uses — for properties within city limits.
- The Kent County Levy Court Office of Inspections and Enforcement issues the building permit, performs plan review against the adopted building code, and conducts inspections.
The two are separate governments with separate authorities. The city doesn't issue building permits; the county doesn't approve zoning. For a project in Dover, the applicant needs both approvals — in sequence.
Why this matters operationally
Kent County won't accept your building permit application without documentation that Dover Planning and Zoning has signed off on the zoning aspect of the project. The document is a zoning official letter from the city, stating that the proposed use and site plan are consistent with Dover's zoning ordinance.
Contractors unfamiliar with this structure typically:
- Prepare drawings.
- Submit to Kent County via My Government Online (MGO).
- Get the application rejected at intake because no Dover zoning letter is attached.
- Discover that Dover city hall is a separate step with its own review time.
- Backtrack to start the city process, losing days to weeks of calendar time depending on how busy Dover P&Z is that week.
Catching this upstream means obtaining the zoning letter first and submitting the county application with the letter attached, which is what Kent County expects to receive.
What Dover Planning & Zoning actually reviews
The city's review focus is:
- Permitted use. Is the proposed use allowed in the property's zoning district by right, conditionally, or only by variance?
- Dimensional standards. Setbacks, lot coverage, building height, parking counts — does the proposed site plan comply?
- Site plan approval. Driveway location, landscape buffers, site circulation — subject to city review.
- Special use permits. Certain uses (liquor, adult entertainment, drive-throughs, telecom towers) require specific city-level approvals.
- Historic district compliance. Downtown Dover and parts of adjacent neighborhoods carry historic designation; properties there trigger additional review.
The output is a zoning official letter confirming that — pending any noted conditions or contingencies — the project's zoning aspects are approved. Conditions are sometimes attached (e.g., specific screening requirements, parking configuration).
What Kent County Levy Court reviews
Once zoning is cleared, Kent County's review is:
- Building code compliance. IBC, IMC, IPC, IEC, NEC applied at the Kent County level with Delaware state amendments.
- Structural review. Structural drawings and calculations for life-safety compliance.
- MEP systems. Mechanical, electrical, and plumbing plan review.
- Floodplain review. For any property in a designated flood zone — Kent County requires a floodplain permit for any work, no size threshold.
- Lines/Grade Survey review. Effective December 1, 2025, covered lots (under 0.5 acres or additions above 500 sq ft impervious) require a survey alongside permit submission.
The county's review doesn't second-guess the city's zoning decisions — they're in their separate lanes.
The practical workflow
- Start with Dover. Schedule a pre-application meeting with Dover Department of Planning and Zoning. Present the proposed use and site plan concept.
- Confirm zoning status. Is the use by-right? Conditional? Variance-required? Get this settled before committing to detailed design — if a variance is needed, the Zoning Board of Adjustment process adds weeks-to-months.
- Submit for zoning approval. Whether staff-level approval (for straightforward projects) or Planning Commission review (for larger projects), the city process runs its course.
- Obtain zoning official letter. This is the gating document for the county step.
- Register in MGO (My Government Online, www.mygovernmentonline.org) if not already registered.
- Submit building permit application to Kent County via MGO, attaching:
- — Dover zoning official letter.
- — Construction documents.
- — Lines/Grade Survey (for covered lots post-December 1, 2025).
- — Floodplain permit or floodplain determination (for properties in or near flood zones).
- — Other required documentation per project type.
- Kent County plan review runs against building code + floodplain + Lines/Grade.
- Permit issuance by Kent County.
- Construction per approved plans.
- Inspections scheduled via MGO.
- Certificate of Occupancy from Kent County.
Scheduling implications
The dual-track process adds serial time that contractors often don't budget for:
- City of Dover zoning review — typically one to three weeks for straightforward projects; longer for Planning Commission-level review or variance situations.
- Kent County permit review — additional time after the county receives the complete application.
- Not parallelizable for the primary path. The county needs the city's letter, so you can't substantially overlap the two steps.
For a standard commercial or residential project in Dover, plan four to eight weeks from initial Dover submission to Kent County permit issuance. For projects involving variances, historic district review, or floodplain complications, longer.
Historic Dover adds a layer
The Dover downtown area, including the Green, the State House, Legislative Hall vicinity, and parts of adjacent neighborhoods, is historically significant. Properties in these areas may trigger:
- Local historic district design review at the city level, parallel to zoning.
- State Historic Preservation Office involvement for listed properties or properties subject to federal tax credit eligibility.
Historic review can add weeks to months and constrain design decisions (materials, window patterns, signage). Like floodplain review, it's an independent track that doesn't fit neatly into the standard city-then-county workflow.
Floodplain work in Dover
Parts of Dover sit in FEMA-designated flood zones, particularly near the St. Jones River and its tributaries. Kent County enforces floodplain requirements strictly — per the county, any work in a floodplain triggers the floodplain permit, without a size threshold.
For a project on a floodplain parcel: confirm floodplain status during property due diligence, incorporate floodplain design requirements into the civil drawings, and obtain the floodplain permit as part of the Kent County submission package.
What to do with this
If you're planning a Dover project: sequence the city zoning step first. Don't start drawings for Kent County submission until you know what Dover's going to approve at the zoning level.
If you're already mid-design and haven't engaged Dover yet: pause. Schedule the city pre-application conversation now. What you learn may affect drawings you're already producing.
If you're a developer doing land due diligence in Dover: confirm zoning, historic district status, and floodplain overlay before closing. All three affect feasibility and timeline.
