What the Delaware County Building Department Handles
Delaware County Building Safety protects public life, safety and welfare by administering adopted building codes, reviewing construction projects, handling inspections, and providing zoning and floodplain resources for applicable areas.
The first step is to confirm jurisdiction. Some properties are inside a city, village, township or municipality that may have separate zoning or permit rules. Even when Delaware County Building Safety handles the building permit, township zoning or other approvals may still be needed before the permit can move forward.
Building permits
New construction, additions, alterations, improvements, replacements and structural work may require plan approval and a building permit.
Inspections
Approved permits usually require inspections during construction and at completion. Check the daily inspection schedule on the morning of your inspection.
Zoning and floodplain
Zoning approval, floodplain review, drainage or township-level questions can affect whether a project can proceed.
Before Applying: Confirm Whether Delaware County or Your City/Township Handles the Permit
This is the most common user-intent gap. People search “Delaware County Building Department” but their property may be inside the City of Delaware or another local jurisdiction.
Question | Why it matters | Practical step |
|---|---|---|
Is the property inside the City of Delaware? | The City of Delaware has its own Building Division and permit portal. | Use the city permit route if your address is inside city limits. |
Is the property in a township? | Township zoning approval may be required even when county building review applies. | Contact the township zoning inspector early. |
Is the property in floodplain? | Floodplain development can require extra review and documents. | Use the county Zoning & Floodplain resources before submitting final plans. |
Is the project commercial? | Commercial projects may need more plan review, fire review, certified address or occupancy steps. | Review the official Commercial Information page and verify related agency requirements. |
How to Apply for a Delaware County Building Permit
A complete submittal saves time. Use official county pages and prepare the right documents before contacting the office or checking portal status.
Step 1: Open permit instructions
Start with the official “How to Apply for a Permit” page so you are following the current county process.
Step 2: Select residential or commercial
Residential and commercial projects have different forms, plan review needs and inspection expectations.
Step 3: Prepare plans and site details
Gather site plan, construction drawings, project scope, owner details, contractor details, zoning information and floodplain information if applicable.
Step 4: Submit correctly
Use the official application route, forms and public portal instructions listed by Delaware County Building Safety.
Step 5: Check status
Search by address in the public portal. If no status appears after the official timeframe, call 740-833-2200.

Delaware County Residential Building Permits
Homeowners commonly need help with decks, additions, garages, sheds, pools, solar, remodels, structural repairs and new homes. The correct documents depend on the project scope.
Residential project | What to prepare | Practical tip |
|---|---|---|
New home | Building permit application, approved address, plans, site plan, zoning, septic/well or utility details where applicable. | Confirm township zoning and driveway/access requirements before final plan submittal. |
Addition or structural remodel | Drawings, structural details, site plan and clear project scope. | Do not describe the project only as “remodel.” Explain exactly what changes. |
Deck or porch | Site plan, framing details, ledger attachment, footing details and guard/handrail details if applicable. | Show distance from property lines and any easements. |
Accessory structure | Site plan, building dimensions, use, drawings or manufacturer specifications. | Check both building permit and zoning size/location rules. |
Pool, hot tub or spa | Site plan, electrical information, barrier/safety details and equipment location. | Do not forget electrical and safety barrier requirements. |
Solar installation | Solar layout, equipment specifications and structural information where required. | Use the county solar guidance and include required engineering support if needed. |
Delaware County Commercial Building Permits and Plan Review
Commercial projects usually require more coordination than residential work. Depending on the use, project type and location, you may need building plan review, fire jurisdiction input, zoning approval, floodplain review, drainage review, certified address and occupancy documentation.
Building plan submittal
Prepare complete construction plans, code details, project scope, occupancy information and site information before review.
Fire jurisdiction
Commercial plan review requirements can involve the appropriate fire jurisdiction. Confirm fire submittal needs early.
Certificate of occupancy
Some commercial projects require certificate of occupancy steps before the building or space can be used.
Drainage and site review
Site changes, drainage mitigation, floodplain or utility issues can affect permit approval and final occupancy.
Delaware County Building Inspections: Scheduling, Daily Schedule and Readiness
After permit approval, inspections are the step that keeps the project legally moving forward. Delaware County Building Safety advises users to check the public portal or inspection schedule on the morning of inspection to verify inspector information.
Have permit details ready
Keep the permit number, property address, inspection type and project contact information ready before scheduling or checking status.
Check morning schedule
Use Today’s Inspection Schedule or the public portal on the morning of inspection to verify assigned inspector details.
Do not cover work early
Framing, footing, foundation, rough electrical, rough plumbing, rough mechanical or insulation work may need inspection before it is covered.
Make access safe
Inspectors need safe access to the site, permit card, plans and work area. Locked gates, animals or unsafe conditions can delay inspection.
Fix corrections
If an inspection fails, correct the exact listed items before requesting re-inspection.
Save final approval
Keep final inspection approval or certificate information with your property records.
Delaware County Zoning and Floodplain Review
Zoning and floodplain issues can stop or delay a building permit even when the building plans are otherwise complete. Always check these before finalizing your project schedule.
Review item | Why it matters | What to do |
|---|---|---|
Township zoning | Townships may control setbacks, permitted use, height, accessory structures and lot rules. | Contact your township zoning inspector before submitting final building plans. |
Floodplain development | Floodplain areas can require special development rules, elevation information and additional review. | Use Delaware County’s Zoning & Floodplain page and ask the office if the property is affected. |
Drainage review | Drainage mitigation can affect final approval and occupancy documentation. | Check county drainage-related updates and plan requirements before construction. |
Certified address | Some new builds and commercial projects need address coordination before permit issuance. | Confirm address requirements before submitting final plans. |
Delaware County Building Safety Forms, Guides, Payment and Permit Reports
Use current official forms only. Old PDFs from search results or third-party sites may be outdated and can cause review delays.
Official resource | Use it for | Link |

Why Delaware County Building Permits Get Delayed
Most delays happen because the application is missing zoning information, the property is in the wrong jurisdiction, plans are incomplete, or inspections are requested before work is ready.
Common delay | What it means | How to avoid it |
|---|---|---|
Wrong jurisdiction | The property may be inside a city, township or municipality with separate rules. | Confirm jurisdiction before submitting. |
Missing zoning approval | Township or zoning review may be required before building approval. | Contact the township zoning inspector early. |
Floodplain issue | Property may need floodplain review or special construction rules. | Use Zoning & Floodplain resources before plan submission. |
Incomplete plans | Reviewer cannot verify the full scope, dimensions, framing, structure or site impact. | Submit clear drawings, site plans and specifications. |
Inspection not ready | Work is covered, incomplete or inaccessible when the inspector arrives. | Schedule only when ready and keep site access clear. |
Payment pending | Permit cannot move forward until required fees are paid. | Use the official credit card payment page or county instructions. |
