It usually comes up casually, as a favor. The contractor says they can save you some money and some time if you skip the permit. They make it sound like a wink between friends — the town is slow, the inspector is a hassle, nobody will know, your neighbors did the same thing. It’s pitched as one of the perks of working with them.
Here is the truth. The person doing themselves a favor is the contractor. The person taking on the risk — financial, legal, structural, and at resale — is you. In the kind of large additions and structural work we do across South Jersey and Pennsylvania’s Main Line, this is the single most expensive lie in the industry, and the one we see homeowners pay for years after the project is done.
What it actually means
Permits exist so that the work in your home is reviewed by someone whose job is to confirm it’s safe and built to code. Framing carries the load it needs to carry. Electrical isn’t going to start a fire behind a wall five years from now. Plumbing isn’t going to leak into the room below. The footing under a new addition is the right depth for the frost line in our climate. The egress windows in a finished basement bedroom are large enough for a firefighter or for someone climbing out. None of that gets verified if no permit is pulled.
When a contractor offers to skip the permit, they’re offering to skip the inspection too. What you save in permit fees you give up in oversight. And the oversight is the part you’re actually paying for. The fee is small. The protection it gives you is enormous.
Why contractors push to skip permits
A few reasons, none of them in your favor.
Sometimes the contractor isn’t licensed to pull a permit in your specific township and doesn’t want you to find out. Each town in our market — Haddonfield, Moorestown, Voorhees, Collingswood, Haddon Township, Haddon Heights on the New Jersey side, Ardmore, Bryn Mawr, Wayne, Villanova, Swarthmore on the Pennsylvania side — has its own permitting office and its own requirements. A contractor running with the wrong credentials, or no credentials, has a strong incentive not to file paperwork that would expose that.
Sometimes the work isn’t going to pass inspection and they know it. The framing isn’t right, the load path isn’t engineered, the electrical wasn’t done by a licensed sub, the plumbing isn’t vented correctly. A permit means an inspector will catch it. No permit, no inspector, no problem — until it becomes your problem.
Sometimes the crew doing the work isn’t actually who the permit would have to be filed under. The contractor you hired isn’t the contractor who shows up. Pulling a permit means putting names on paper, and the names don’t match.
And sometimes the answer is simpler. They just don’t want to schedule inspections because it slows them down. Inspections mean waiting on the township calendar. Waiting means the crew sits. A crew that sits costs money. A slower schedule means they can’t move on to the next deposit. So they pitch you on skipping the permit as a favor when the favor is to their cash flow.
All of those are their problems. The minute you agree to skip the permit, they become your problems.
What it looks like in practice
The most common version we see plays out at resale. A homeowner in Haddon Township finishes a basement with a bedroom and a full bath, no permit. A homeowner in Moorestown adds a sunroom off the back of the house, no permit. A homeowner in Wayne puts a second story on a ranch, no permit. Years later, the house goes on the market. The buyer’s inspector flags unpermitted work. The deal stalls. The township is brought in. The town wants the work opened up — drywall removed, framing exposed, electrical traced back — inspected, and either approved retroactively with whatever corrections are required or torn out and rebuilt. Whatever was saved on the front end is gone, plus more, plus interest, plus a buyer who is no longer sure they want the house. Some deals close anyway, at a significant price reduction. Some don’t close at all.
The slower version plays out at refinance. Appraisers walk the house. The square footage on file with the town doesn’t match the square footage in front of them because the addition was never permitted and the tax record never updated. The appraisal comes back wrong. The refinance stalls. The homeowner finds out, in the worst possible context, that the work in their house isn’t on the books.
The worst version we ever see is an insurance claim. A fire, a water loss, a structural failure in unpermitted work, and the insurer’s adjuster points to the lack of permits as grounds to deny or reduce the claim. Suddenly the savings on the permit fee are not just gone — they are dwarfed by the loss the policy was supposed to cover. That phone call to the insurance company is one no homeowner should have to make, and we have seen homeowners make it.
What gets permitted in our market
If you’re not sure whether your project needs a permit, the answer in New Jersey and Pennsylvania is almost always yes. Anything that involves structural changes — adding square footage, opening a load-bearing wall, putting a second story on a ranch or a cape, building a rear or side extension — requires a permit. So does new electrical work beyond a like-for-like fixture swap, new plumbing, new HVAC, new gas lines, new windows or doors where the rough opening changes, finished basements with sleeping areas, and most decks. Townships vary on smaller items, but the projects we work on never sit in the gray area. They are always permitted work.
If a contractor tells you a second story addition, a major rear extension, a mother-in-law suite, or a finished basement bedroom doesn’t need a permit, they are wrong, and they know they are wrong. There is no version of that conversation that ends well for the homeowner.
What to do if you hear it
The minute a contractor suggests skipping a permit, the conversation is over. Not negotiable. Not “let me think about it.” Over. A contractor willing to cut that corner is telling you, out loud, what other corners they’ll cut once your house is open and your check has cleared. It is the single most useful filter a homeowner has during the vetting process, because it sorts the people who run a real business from the people who don’t, in a single sentence.
If you’re not sure whether your specific project needs a permit, ask your township directly. The construction office in every town in our market will answer the phone. Or ask a contractor whose name you’d trust with your house. A reputable contractor will tell you, plainly, what is permitted and what isn’t, and the answer in our climate, our soil, and our local code is almost always that the work you are considering needs to be on the record.
What MAG does instead
We pull every permit our work requires, in every township we work in. Inspections happen on the schedule the township sets, and the permits get closed out at the end of the project so the work is on record with your town and reflected in the property record. You will never hear “we can skip that” from us, on any project, at any price. See how we run home addition projects, how we approach second story additions in New Jersey, or how we build mother-in-law suites.

Common questions
Are there any home improvements that genuinely don’t need a permit?
A few. Painting, like-for-like cabinet refacing, flooring on an existing subfloor, swapping a light fixture for the same type, minor cosmetic work. The boundary varies by township and changes over time. For anything structural, electrical, plumbing, HVAC, or square-footage-adding, the answer in our market is yes, you need a permit. If the project is large enough that you’d describe it as an addition, a renovation, or a remodel, it needs a permit.
What happens if I find out work in my house was done without a permit before I bought it?
You have options, none of them as easy as the original permit would have been. You can apply for an as-built permit, which the township will review and may require you to open walls for inspection. You can get a structural engineer to certify the work, which sometimes satisfies the town and sometimes doesn’t. You can disclose the work as unpermitted at resale and price accordingly. The longer it sits, the more it costs to resolve. The cleanest move is to address it before you list, not after a buyer’s inspector finds it.
Does pulling a permit raise my property taxes?
It can, because permitted square footage is reflected in your assessment. That is part of the trade-off, and it is also one of the reasons some contractors push to skip them. The number to weigh it against is not the tax increase, though — it is the value of the work being on the record, the warranty being enforceable, the insurance being valid, and the house being resaleable without a fight. Unpermitted work doesn’t avoid taxes. It just defers the cost to a worse moment.
If the contractor says they’ll “handle the permit,” is that the same as pulling one?
It should be, but verify. Ask for the permit number once it’s been issued. Ask to see the permit posted on site during construction — it should be visible from the street. Ask which inspections have been called and passed at each phase. A contractor handling the permit responsibly will have no problem walking you through any of this. A contractor who claims to have handled it but can’t produce the number is telling you it was never pulled.
What if I’m worried about delays from the permit process?
The permit timeline in our townships is usually weeks, not months, and a reputable contractor builds that into the project schedule from the start. Any delays you’re avoiding by skipping the permit are dwarfed by the delays that come from a failed inspection, a stop-work order, or a resale issue years later. Permits are the slow, boring part of the project that protects the fast, exciting part from collapsing.
