Most permit headaches start the same way: someone buys materials, books a weekend, maybe even digs a hole, and only then finds out the town wanted a permit, a drawing, or a different setback. The fix is boring and effective. Ask a few good questions before you spend anything.
Permit offices get a lot of vague calls. "Do I need a permit for a deck?" is a fine question, but it usually gets a vague answer, because the honest answer is "it depends." These five questions are specific enough to get specific answers, and together they cover most of what you need to know for a typical home project.
Before you call, have three things ready: your address, a one-sentence description of the project, and a rough sketch with sizes. That alone puts you ahead of most callers.
1. "Does this project need a permit, and which kinds?"
Start with the obvious one, but ask it in a way that gets a complete answer. Many projects need more than one kind of approval. A deck might need a building permit and a zoning permit. A bathroom remodel might need building, plumbing and electrical permits. A shed might need only zoning approval. If you only ask "do I need a permit?", you might hear "yes" and miss that there are two.
Describe the project plainly: what you're building, how big, where on the lot, and whether it involves plumbing, electrical or gas. Then ask, "Which permits or approvals will this need?"
If the answer is "no permit needed," ask one follow-up: "Is there anything that would change that?" Sometimes a small change, like adding an outlet or going a little taller, flips the answer.
2. "What rules apply to my project, and where can I read them?"
Permit offices work from adopted codes, local amendments, and the zoning ordinance. Ask which ones apply to your project, and where you can read them. Many towns post their zoning ordinance online, and many publish handouts for common projects like decks, fences, sheds and pools. A handout written by your own town is gold, because it reflects how that office actually reads the rules.
This is also the moment to ask about local quirks. Is your property in a historic district? A floodplain? Is there an easement on your lot? These come up more often than people expect, and they change the rules.
3. "What do you need to see in the application?"
This question saves more time than any other. Offices differ a lot on what they want. Some accept a hand-drawn site plan with measurements. Others want a scaled drawing. Some want product sheets for things like composite decking or a prefab shed. Some want drawings from a licensed professional for certain projects.
Ask for the list. Ask whether there's a checklist or an application form online. Ask whether the application can be emailed or must be filed in person. And ask the question that catches most people out: "What's the most common reason applications like mine get sent back?" The answer tells you exactly where to be careful.
4. "Which inspections will I need, and when do I call for them?"
A permit isn't just a piece of paper you get at the start. It usually comes with inspections at specific stages: footings before concrete, framing before it's covered, rough plumbing and electrical before walls close, and a final at the end. Miss one and you may have to open up finished work so the inspector can see it.
Ask which inspections apply, at what stage, how much notice the office needs, and how to schedule them. Put them on your calendar alongside your work plan.
5. "Can I do this work myself, or does it need a licensed or registered contractor?"
Rules on who may do the work vary widely. Some towns let homeowners pull permits and do most work on their own home. Some require licensed electricians and plumbers for that work. Some require contractors to be registered with the town or state. If you're hiring someone, ask who should pull the permit. In many places it should be the contractor, and the permit holder is responsible for the work.
A few habits that help
- Write down the answers, with the date and the name of the person you spoke with. If you get a different answer later, you'll know where you stand.
- Ask for things in writing when the answer is surprising, especially an answer that says you don't need a permit for something sizable.
- Be friendly and brief. Permit staff are often stretched thin. A clear question with a sketch gets the best help.
- Call the zoning office too, if it's separate. Building and zoning are sometimes different departments with different phone numbers.
Why we built Sully around these questions
These five questions are close to the outline of the permit report Sully builds. Sully reads your town's own pages first, then the county, then the state, then the model code, and labels every rule with where it came from. The report gives a verdict (required, likely, unclear or not required), the rules grouped by source, fees and contacts checked against the pages Sully read, the town's form when it's posted, ordered steps, common rejection reasons and whether to hire a pro.
And when Sully can't find something your town hasn't published online, the report says so and tells you who to call, with these questions ready to ask. We think that's more useful than a confident guess.
Check with your local permit office
This post is general guidance, not your town's rule. Requirements, fees and timelines vary by town, and your local permit office makes the final call.
