Before adding a prefab garage to your property, it’s important to know if you’re allowed to do so. In this guide, we’ll explain what to expect when applying for garage permits in Delaware, and help you plan your next steps with confidence. And if you’re considering options, feel free to explore our Garage Models, or try out our 3D Builder to start designing the garage that fits your space and your style.
Yes. In most cases, you will need a garage permit in Delaware to build a garage. Permits help ensure that your garage meets structural codes, follows zoning regulations, and doesn’t cause problems with property lines or neighbors. Keep in mind that permits can vary from town to town, so it’s best to check your local planning or zoning office for specific details.
What is the biggest garage you can build without planning permission?
There is no single statewide size limit that allows a garage to be built without a permit in Delaware. Requirements depend on the county and municipality.
In New Castle County, a detached accessory structure over 200 square feet requires a building permit. Smaller structures may be exempt, but zoning rules still apply, including setbacks and placement.
In Kent County and Sussex County, a permit is required for all garages, regardless of size.
Even when a building permit is not required, zoning compliance is still mandatory. Always confirm requirements with your local building or zoning department before construction.
Do I Need a Permit to Run Electricity to My Garage in DE?
Yes. You will need a permit for any electrical work in your garage in Delaware.
Installing wiring, outlets, lighting, or a subpanel requires an electrical permit.
Homeowners may apply for a Homeowner Electrical Permit only if they live in the home and perform the work themselves.
If a licensed electrician is hired, they are responsible for obtaining permits and scheduling inspections.
While electrical permitting follows state building codes, counties may require additional inspections. Always check with your local building department before starting electrical work.
Garage permitting in Delaware is administered at the county level, with local zoning oversight by towns and cities, so the process can vary a bit depending on where you live.
Here’s a concise overview of what you need to know for all DE counties:
As we mentioned earlier, garage permit requirements can vary depending on the municipality. Cities in Delaware often have their own specific rules and processes. In this section, we’ll take a closer look at the permit process for some cities across Delaware.
If you live in an incorporated area like Newark, Dover, or Rehoboth Beach, check with your town’s planning or building office directly, as they may have their own requirements. For projects that include electrical work, a separate electrical permit may also be needed, especially if you’re installing lighting or running power to the garage.
The cost of a garage permit in Delaware depends on where you live and how big your project is. Each county and municipality sets its own rates based on the value and scope of construction.
In New Castle County, expect to pay around $12 per $1,000 of construction value, with a minimum total fee of about $142. This includes review fees, a certificate of occupancy, and contributions to local fire services. Larger garages (over 480 sq. ft.) may also require a $60 grading review.
Kent County does not list a flat garage permit fee, but all building permits include a required school district surcharge totaling 1.25% of construction value, with final permit costs calculated by the county during the application process.
In Sussex County, fees vary depending on construction value and whether the project affects more than 5,000 sq. ft. of land. Additional costs may apply for erosion control plans and inspections.
If you live in a city or town like Newark, Dover, or Dewey Beach, you may need to pay local permit fees. For example, in Dewey Beach, the building permit fee is about 3% of the total construction cost. In Newark, they use a fee schedule based on the value of the construction, calculating the cost per $1,000. Permit fees can vary a lot depending on where you are. To get an accurate estimate, it’s best to contact your local building department directly.
How long does it take to get a Garage permit in DE?
At present, Delaware counties and municipalities don’t have a fixed processing timeline for garage permits posted online. Permit review and approval times may vary depending on:
The completeness of the application
Project scope
Zoning and code review requirements
The workload of the local building department
Applicants can track status through online permitting portals and should contact their county or city building office for the most accurate estimate.
How long does a Garage permit last in DE?
In Delaware, the validity period for a county building permit generally depends on the issuing county’s code and the specific permit conditions:
New Castle County
A building permit must be initiated within the designated timeframe, and inspections must be arranged in accordance with county regulations. New Castle County also allows permit extensions of up to 180 days per period with an $80 fee per extension period, though this is a policy and not a straight “one-year rule.”
Kent County
Kent County does not publish a specific expiration period on the county’s high-level permit info. Still, like most jurisdictions, permits become void if work isn’t started or maintained according to the county’s building code requirements. Contact Kent County inspections for specifics.
Sussex County
Sussex County also does not publicly list a fixed expiration timeframe on its basic permit pages, but permits typically require active construction progress or inspection scheduling to remain valid once issued, and delays may require contacting the permit office.
Municipalities
Municipalities can vary their expiration rules slightly, so it’s always best to check the local city/town building department for exact permit expiration and extension rules.
What is the penalty for not getting a Garage permit?
The penalty for not getting a garage permit in Delaware can be problematic, as it can result in the following enforcement actions:
General enforcement
Building departments can issue stop-work orders, require retroactive permit applications, and levy fines for work done without a permit.
Each day the violation continues is often treated as a separate offense under local code enforcement.
County practices
New Castle County and other county departments have procedures to enforce compliance and may compel you to obtain proper permits or remove non-compliant work.
Sussex County typically requires permits for all construction and enforces compliance; repeat or prolonged violations can result in escalating penalties.
Insurance and sale implications
Adding a structure without a permit can lead to denied insurance claims, difficulty selling the property, and complications during refinancing or title transfer because the unpermitted structure lacks documented approval.
Always check with your local county or municipality and apply for permits before beginning work to avoid fines, stop-work orders, and complications with insurance and future resale.
Here’s an accurate summary of what’s typically required:
State and County
A building permit is required for garage construction (attached or detached) in all three Delaware counties because it involves new construction and structural work.
Documentation
Common requirements include:
A completed county permit application.
A site plan showing the garage’s location and setbacks.
Construction drawings with details such as foundation, framing, and structural notes.
Additional trade permits (e.g., electrical) if applicable.
Sussex County: Permits are usually obtained at the county’s Georgetown office; in some cases, plans must be submitted in person.
Municipal areas
Cities such as Newark, Dover, Rehoboth Beach, Wilmington, and others may have their own permit processes and rules that add to county requirements. Check with your local city building department for details.
Before you buy or build a garage in Delaware, make sure you have all the necessary information and approvals in place. Again, we suggest checking with your local municipality since every city and county has its own rules regarding what you’re allowed to build and at what size, location, and if you’re allowed to install electricity.

We had a new pad and shed installed yesterday. The whole process leading up to the purchase and through the installation went smoothly. Zack McCann from sales and Michael Stoltzfus from shipping made the whole process easy. Chase and Steve did the installation at our house. Amazing to watch. They did a great job and were nice to talk to. The shed should serve us well. Very pleased. I would recommend Sheds Unlimited.

My experience from Sheds Unlimited was great. The website is very professional and informative. Working with Ryan to get our shed exactly how we wanted it was a pleasure and painless. Communication from the office about build schedule and delivery was spot-on. Upon delivery Nate was great. He was very informative about the shed and meticulous on moving it to its location. Once he set the shed he asked us if we liked the location. We checked it and wanted it 3″ closer to the house. He was very happy to nudge it over and he saw how happy we were with it. It was a great experience from a great company. This is the only company to purchase a shed from. In the near future we are looking to have a garage installed and it will be from Sheds Unlimited. Thank You!!!

Thank you Samantha!!!!!
We purchased a shed in 2014 from Sheds Unlimited and were looking to repaint it. I contacted Sheds Unlimited and inquired about the paint colors used on our shed and Samantha stated she would look into my request and give me a call back. Two hours from my initial call, Samantha contacted me with our color scheme information as well as the name of the paint company and contact number. She also informed me that the name of one of the colors used had changed and provided me the new color name. Without her research and assistance, our color scheme would not had been what we wanted and we would have spent more money than we needed to. Samantha went above and beyond in assisting us with the paint we needed for repainting our shed and we sincerely appreciate it.
Again, Thank you Samantha!!!

The shed is exactly what I wanted and the quality of materials and workmanship are awesome. There are zero issues with the finished product. The Install coordinator was very responsive to all my questions about delivery and construction of the pad site. The entire staff were very knowledgeable and reactive to my needs in the purchase process, The Installers were extremely professional in setting the shed up on my property.
Thank you, Ron
New shed with stone foundation was done today. Everything was great ! The crew was friendly and everything was done exactly as expected. If you need a new shed you need Sheds Unlimited.

Our Sheds Unlimited experience began on their informative website. We used their on-line design tool to create our shed, and the project flowed smoothly from design to delivery. Our site is very steep, and I truly doubted they would be able to deliver our 12’ X 14’ shed. They committed to delivery after reviewing pictures of our narrow street and steep hillside yard. Nate is a master equipment operator. He had our shed sitting perfectly level on our pad about 30 minutes after arrival. I was amazed by what he could with their specialized equipment. Fantastic work Sheds Unlimited!!
Sheds Unlimited tailored a classic shed to fit my existing 10’x12′ concrete slab, stiffened the floor, and added 6 ft. doors for a large mower. Steve Wagner, sales rep, estimated 4-6 weeks to build it.

Anthony delivered the shed just shy of 6 weeks. It was neat watching him off-load and move the shed using the remote control ‘mule’. Our bumpy terrain didn’t phase him getting to the pad. He patiently maneuvered it so that the shed sits squarely on the pad. Anthony inspected the shed (roof, siding, windows, doors) to make sure nothing was misaligned. He obviously is a good employee, confident, skilled, and experienced dealing with delivery ‘opportunities’ and anxious customers.
The left-behind two page Building Quality Control checklist showed how much detail and quality went into building the shed.
All in all Sheds Unlimited built and delivered a superb shed.

Can’t say enough nice things about these guys. Dealt with Cleon for ordering. Very friendly and easy to work with. Their customer service is second to none. Even the delivery guy was very nice. Had to replace a door that was damaged in a storm and they were able to build a new one for me quickly and at a very reasonable price. I would absolutely order another structure from them in the future, and plan to refer friends and customers looking for a well-built structure to look into Sheds Unlimited

What can I say about Sheds Unlimited that hasn’t been said? The process to design what I wanted could not have been easier, the delivery was spot on time and the installation crew (Gideon, Joshua and Leroy) was awesome! I could not say enough good things about Sheds Unlimited, I highly recommend them!

I started this process of building a garage 2-3 years ago. I called local builders. Two of them never returned my calls, and one guy chewed me out for finding his number on the web and calling him without being referred by someone. I’m not kidding, this is how the building contractor experience is right now in New England. My web searches always turned up Sheds Unlimited and I saw that they had stories from folks in New England who had used them to build garages even though they are in Pennsylvania. I decided to go through the quote process. There was a similar shed & garage company closer to my home in New England so I got quotes from both of them for similar garages. The New England company quoted me a number that was 2 1/2 times higher than Sheds Unlimited quote. I decided to go with Sheds Unlimited. I worked with Sergey in sales over many emails on exactly what I wanted. There was never a moment when he seemed bothered or impatient by my questions and my changes. Everything was possible and everything had a clear dollar amount, the sale never felt rushed. I finally decided on a design and paid the deposit. The local permit process went smoothly with the plans I purchased from Sheds Unlimited. The process of getting a foundation and pad from a local contractor was probably the most difficult part of the process. Contractors that do concrete work, are used to working with builders, not private homeowners. But I found a guy and gave him the plan and I eventually got a nice pad and foundation. I told Michael from Sheds Unlimited the pad was ready and I expected to wait 10+ weeks since it was now summertime. I got the call only 5 weeks later from Gideon the project manager that they were ready. On the scheduled day Nathan and his crew of 3 young, hard working Amish carpenters arrived and discovered that my driveway was the worst-case scenario. They could not get their very long and heavy trailer up our driveway due to the tightness of the turn and narrowness of the driveway. So they had to unload everything from the trailer at the road to my build site which is about 900 feet from the public road. They dealt with local vehicle traffic, and unhelpful local police. The young crew had to run back and forth the 900 feet to walk alongside the forklift to make sure the preconstructed structural members did not swing into trees. Not once did they show any frustration or anger. Nathan was still positive and smiling when I talked with him about it later. So after all this arrival difficulty, when they finally starting constructing the garage, it went up incredibly fast. Every worker knew their part. There was no question about what they should be doing. They practically got the whole 2-story 2 car garage up in one day even after the delay from the driveway issues. They only stopped for the day when torrential rain finally started. They showed up at 5:30 AM the next day and finished the job. I can’t say enough great things about what I witnessed with this construction crew. Like I said, I have never seen anything like them in 26 years of hiring various contractors for home projects.
If you are considering a garage or shed, don’t even think twice. Contact Sheds Unlimited today. I guarantee you have never worked with any company as satisfying as them.
