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 prices most small home jobs as flat minor-alteration permits: $69 for a roof covering or siding, $75 for a new deck, plus $7.50 in city and state surcharges on every permit. Full alterations bill by floor area, not project cost. I pulled these numbers straight from the City of Philadelphia construction permit fee schedule and its permit pages.
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 one and two family homes run flat fees, and every permit adds a $3 city surcharge and a $4.50 state surcharge. Roof covering replacement costs $76.50 all in. Exterior siding runs the same. A new deck costs $82.50. An AC unit or heat pump changeout runs $76.50.
Electrical work costs $25 per $1,000 of electrical cost with a $63 minimum. A water heater is $31 before the surcharges. Full alterations bill by floor area: $76 for the first 500 square feet plus $56 for each additional 100. Applicants can instead ask for 2% of construction cost with a $253 minimum, but the floor-area fee is the default and usually the cheaper one.
We built the calculator on this page using those exact rates. Punch in your project details. It shows you the trade-by-trade breakdown. (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, plus the $7.50 in surcharges.
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, and remodels bill by the square foot instead of the price tag. Always tell your customers the permit cost up front. Nobody likes a surprise bill after they already signed."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
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 one and two family homes keeps many jobs cheap. A full roof replacement costs $76.50 whether the job runs $12,000 or $25,000. Same for siding. Full alterations switch to the floor-area fee, and only climb with cost if you ask for the 2% option.
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.
