Permits. The Good, the Bad, and the Ugly.

TLDR
A permit gives you a built-in inspector, an official record, and another check on the work. It can also add fees and time, and the scope may grow if open walls show old problems. Ross’s stories ranged from useful review to tens of thousands in new work.

The Good

Start with what you gain. A permit gives you a built-in inspector. That can help when you do not know the work well yet. The review is part of the paid permit process, not a free service. The city checks the job against its chosen code.

Ross’s example involved adding 200 square feet in a market where he used $400 per square foot. His point was that permits update the official square-footage record, which can matter when the house is sold. He did not say the value loss is always exactly $80,000.

Pro Tip
An unrecorded addition can make the square footage and its value harder to support at resale. The $80,000 figure was Ross’s arithmetic for one 200-square-foot example.

Ross named three more gains. First, you are not trying to hide the work from the city. He remembers covering windows with black trash bags and ducking when a code-enforcement truck passed, even though the early projects were mostly cosmetic and, in hindsight, often may not have needed permits. Second, a permit record can answer questions when agents check the job at sale time. Third, a passed check gives you a city record of what was reviewed. Ross said that record gives an owner more ground to stand on, but he also said he did not know how a later court case would turn out.

And last: contractors need the required licenses to pull permits. Requiring the right permit therefore gives you another useful check on whether a contractor has gone through some basic legitimizing. It is not a complete screening system.

The Bad

The cost is real. Permit fees come first. Some cities also ask for plans stamped by an engineer. On one commercial job, Ross was not touching the mechanical, electrical, or gas systems and was only doing plumbing work. Even so, the city required a building permit plus mechanical, electrical, plumbing, and gas permits. He also needed engineered trade plans, an architect, and a landscape engineer. Each requirement added cost. Contractors may charge more for the added work too.

Time can hurt more. That same job ran over a year in Ross’s account. Plans went in, the city reviewed them, and changes went back for more review. Work and checks followed. A failed check meant another crew visit. Ross also said a Denver home rehab took more permit time than a Tennessee business job. Place matters.

Then there is scope expansion. Existing work may be grandfathered when it met the code in effect when it was built, while other work may have to be replaced. You cannot know every decision before the city sees the actual condition. More scope means more time and more cost.

Permits also add work to manage. On Ross’s jobs, he tracked build and trade permits in city sites. He booked checks, reset failed checks, and answered the reviewer. The exact permit stack depends on the job and city.

The Ugly

The worst stories were not about fees or dates. They were about what appeared inside open walls. Ross described jobs that grew into new plumbing to the road, a street cut, and roughly $30,000 of added work. He also recalled full rewires and other full plumbing jobs.

A worse case can lead to condemnation and a separate process to clear it. Ross said shocks like this can blow up a project or even a business when the owner lacks the cash or skill to manage them.

Scope Can Expand
Once an inspector sees an older condition behind an opened wall, the project may have to address more than the original scope. Ross described this as the costly part of the permit process.

The city is doing a job. The hard part is often the real state of an old house, not the permit itself. A careful walk and a clear risk baseline can help, but they cannot reveal every hidden issue.

Permits remain part of the business. Learn the rules of the game and use them to make better decisions.

FAQ

If I know I’ll get hit by scope creep, should I just skip permits?

No. Follow the permit rules that apply to the job. The source shows how work without a permit can create sale, inspection, and legal risk, but it does not predict one result in every city.

I’m on my first flip. Does cosmetic work need permits?

Ross described cosmetic work and system work as different categories, but the source repeatedly qualified the rules by municipality. The article cannot turn that distinction into a universal permit list.

How do I pick a contractor who handles permits well?

Requiring the permit shows whether the contractor holds the license needed to pull it. Ross treats that as one sign that the contractor has gone through some legitimizing, not a full hiring test.

Does this change if I’m a licensed general contractor myself?

Ross discussed his own experience as a GC managing the general permit while his mechanical, electrical, and plumbing company managed trade permits. His license did not remove the plans, portals, checks, failures, or follow-up work.
