Two Types of Permits
Philadelphia issues building permits for structural work and separate trade permits for plumbing, electrical, HVAC, and roofing. Most remodels need both kinds. See the full breakdown of which projects need a permit and which are exempt.

Philadelphia charges a flat $253 for most small home projects under $12,000. That same $253 covers a $8,000 bathroom remodel or a $12,000 roof job. At $25,000 the fee jumps to $500. I pulled these numbers straight from the City of Philadelphia Permit Fee Schedule effective January 2025.
Philadelphia Permit Fees Explained
Philadelphia uses a separate trades permit system. You pull individual permits for each type of work instead of one big building permit. Minor alteration permits for owner-occupied one and two family homes run flat fees. Roof covering replacement costs $69. Exterior siding runs the same $69. A small deck under 200 square feet costs $63. HVAC appliance changeouts run $69.
Electrical work costs $25 per $1,000 of electrical cost with a $63 minimum. General demolition runs $25.30 per 100 square feet but never below $253. Full alterations bill by floor area. $76 for the first 500 square feet plus $56 for each additional 100. Applicants can instead request 2% of construction cost with a $253 minimum. On that path an $8,000 project pays $253. Same at $12,000. It becomes $500 once you hit $25,000.
We built the calculator on this page using those exact rates. Punch in your project details. It shows you the trade-by-trade breakdown. Pennsylvania also rides a small state training surcharge on every permit. Not huge. But it adds up. (The fee schedule PDF only makes sense next to Title 4 of the Philadelphia Code, which is where the minor alteration bucket gets defined.) The minimums kick in often here. That protects the city from tiny fees. It also means your $3,000 electrical panel upgrade comes to $75, three $25 units on the meter.
Chuck's Take
"Chuck here. I bid jobs in Missouri but these Philadelphia numbers make sense. The flat fees for small jobs keep things reasonable until you hit that $25,000 mark. Then it doubles. Always tell your customers the permit cost up front. Nobody likes a surprise $500 bill after they already signed."

What Needs a Permit in Philadelphia?
You need a permit for most exterior changes and any work that touches structural, electrical, plumbing or mechanical systems. Roof replacement needs one. So does new siding. Window and door replacement only requires a permit if your building is historic.
Decks need a permit. Same for finishing a basement or major bathroom remodel. But you don't need one for ordinary repairs that don't cut walls or change egress. Non-masonry fences six feet or under are exempt. Minor plumbing fixes like swapping a faucet with the exact same type don't need a permit either.
Electrical work follows strict rules. Low voltage in one and two family homes is exempt but most other changes trigger a permit. Do I need a permit in Philadelphia to replace a roof? Yes. Do I need a permit in Philadelphia for a fence? It depends on the height and material. Check before you start. The exemptions look generous on paper. They aren't when code enforcement shows up.
What Happens If You Skip the Permit in Philadelphia?
Philadelphia doubles your cost if they catch unpermitted work. They charge an inspection fee equal to the original permit fee. Then they add fines up to $300 per offense. Each day counts as a separate offense. That adds up fast.
Sections A-901.13 and A-601.1 spell this out. They can also issue stop-work orders under A-504.8. Nobody wants that headache. Plus, the city doesn't play around with enforcement.
I saw the penalty language buried in the code. It isn't friendly. Pull the permit up front. It always costs less than fixing it later.
How Long Is a Building Permit Good For in Philadelphia?
Your permit expires if you don't start work within six months of issuance. Same rule if you abandon the job for six months. Section A-302.2 covers this.
You can get extensions. Owner-occupied one-family homes get them free. Everyone else pays $50. Max two extensions to start work. Plus, one extension for suspended work. Rough-in permits die after 60 days if not finished.
Plan ahead. These clocks don't pause for weather or supply chain problems.
Who Should Pull the Permit in Philadelphia?
Owners, lessees, registered design professionals or licensed contractors can pull permits. If you're not the owner you need a signed statement from them. You must list every licensed contractor by name and license number.
Contractors have to identify themselves on the application. Plumbing requires a Registered Master Plumber. Electrical contractors need a separate city license. All construction workers must have OSHA 10.
Your contractor should pull the permit in their name. Not you. If they ask you to pull it that's a red flag. They want to avoid liability. Don't do it.
Chuck's Take
"I never let a homeowner pull the permit on my jobs. Ever. If a contractor in Philadelphia asks you to do it walk away. They're dodging responsibility. The city wants the licensed contractor's name on the application for a reason."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
Philadelphia's Separate Trades System
Philadelphia stands out because it doesn't bundle everything into one building permit. You pull separate permits for roofing, electrical, plumbing, mechanical and demolition. This creates more paperwork. It also means you only pay for what you're actually doing.
The minor alteration category for owner-occupied homes keeps many jobs cheap. A full roof replacement costs $69 whether the house is valued at $12,000 or $25,000 in work. Same for siding and small decks. But once you cross into full alterations the 2% of cost formula kicks in hard.
The state adds a mandatory training surcharge on every permit. Philadelphia also enforces extensive local amendments to the 2018 IBC and IRC. They're transitioning to the 2021 codes in July 2026. The city never makes it simple. But the numbers are predictable once you know the buckets.
