Fee	Amount	Notes
Philadelphia L&I building permit fee (sheds over 200 sq ft)	$100–$350 (estimated)	Philadelphia L&I permit fees for residential accessory structures are based on project valuation. A typical residential shed ($5,000–$15,000 value) falls in this range. Verify current amounts at eclipse.phila.gov.

Timeline

Typical timing

Plan review: 10–20 business days for standard residential review
Total cycle: 3–7 weeks from application to final inspection for a permitted shed

Philadelphia Historical Commission review for historic district properties adds 4–8 weeks. ZBA variances (for sheds that exceed zoning height or setback requirements) can add 2–4 months before the permit application is accepted. Utility trade permits are reviewed and inspected on separate tracks.

Process

How the permit process works

Apply Philadelphia's 200 sq ft threshold as the first filter Under the PA UCC as enforced by Philadelphia L&I, accessory structures including sheds at 200 square feet or less in footprint area may be exempt from the building permit requirement, provided they meet Philadelphia Zoning Code setbacks and height limits and have no utility connections. Sheds over 200 sq ft, sheds with utilities, and multi-story structures require a permit. All sheds must still comply with Philadelphia Zoning Code placement requirements.
Verify zoning placement using the Philadelphia Atlas Use the Philadelphia Atlas at atlas.phila.gov to identify the property's zoning district and confirm applicable rear yard and side yard setbacks, maximum lot coverage, and maximum accessory structure height under Philadelphia Zoning Code Title 14. Setbacks vary by residential zoning district. Confirm compliance before ordering a prefab unit or pouring footings.
Screen for Philadelphia Historic District review Check whether the property is in a designated Philadelphia Historic District using atlas.phila.gov. If it is, contact the Philadelphia Historical Commission at phila.gov/departments/philadelphia-historical-commission before placing or ordering the shed. A Certificate of Appropriateness is required for sheds visible from a public right-of-way in designated historic districts, and this approval must be obtained before L&I will accept the permit application.
Determine utility scope and plan trade permits Decide whether the shed will have electrical wiring, outlets, lighting, plumbing, or mechanical systems. Any utility connection requires a separate Philadelphia L&I trade permit and inspection, regardless of whether the shed's footprint size is building-permit-exempt. Plan trade permits alongside the main permit application.
Select an appropriate foundation for Philadelphia conditions The Philadelphia frost line depth is 36 inches. Permitted sheds must have footings that comply with PA UCC requirements for the applicable structure type. Small prefab sheds on treated wood skids or shallow piers may be acceptable for exempt-sized structures; larger site-built sheds over 200 sq ft typically require concrete piers or a full slab extending below the 36-inch frost line.
Submit through eCLIPSE and undergo plan review For permitted sheds, apply through L&I's eCLIPSE portal at eclipse.phila.gov. Submit the site plan, shed drawings, foundation details, and any Historic Commission approvals. PA UCC structural review and Philadelphia Zoning Code zoning review typically takes 10–20 business days. Correction notices are issued through eCLIPSE; revise and resubmit through the portal.
Pay fees, post permit, and build; complete inspections After approval, pay fees through eCLIPSE and post the permit card on site before beginning work. Request required inspections through eCLIPSE or by contacting L&I. Typical shed permit inspections include a footing inspection (before concrete pour), a framing inspection, and a final inspection. Trade inspections are scheduled separately.

Code basis

What Philadelphia reviews against

Pennsylvania Uniform Construction Code (PA UCC), based on the 2018 International Residential Code (IRC) with Pennsylvania amendments, as enforced by the Philadelphia Department of Licenses and Inspections (L&I); Philadelphia Zoning Code (Title 14) for accessory structure placement, setbacks, and height limits.

What can go wrong

Philadelphia L&I can issue a stop-work order and require removal or correction of unpermitted shed construction.
A shed placed in a required setback or exceeding lot coverage limits can be ordered relocated or removed at the owner's expense.
After-the-fact permits in Philadelphia may require exposing foundation elements and framing for inspection, adding significant cost and delay.
Unpermitted electrical or plumbing work creates fire, shock, and water-damage risks that go unverified without L&I trade inspections.
Philadelphia Historic District violations can result in enforcement action by the Historical Commission separate from L&I building code enforcement.
Civil penalties assessed by L&I accumulate until violations are resolved, and unresolved violations appear in L&I's public records.
Pennsylvania seller disclosure requirements mean known permit violations must be disclosed in residential real estate transactions, affecting sale price or requiring remediation before closing.

FAQ

Common Philadelphia shed permit questions

Do I need a permit to build a shed in Philadelphia, PA?

It depends on size, utilities, and location. Under the PA UCC as enforced by Philadelphia L&I, accessory structures at 200 square feet or less in footprint area that meet Philadelphia Zoning Code setbacks and have no utility connections may be building-permit-exempt. Sheds over 200 sq ft and any shed with electrical wiring, plumbing, or mechanical systems require a permit. All sheds must still comply with Philadelphia Zoning Code placement requirements for the applicable zoning district.

Does Philadelphia's historic district affect my shed permit?

Yes. Properties in designated Philadelphia Historic Districts — including Society Hill, Old City, and other areas — require a Certificate of Appropriateness from the Philadelphia Historical Commission before placing a shed visible from a public right-of-way. This approval must be obtained before L&I will accept the permit application. Check your property's historic district status at atlas.phila.gov, then contact the Historical Commission at phila.gov/departments/philadelphia-historical-commission early in the planning process.

What are Philadelphia's shed setback requirements?

Philadelphia does not have a single universal shed setback. Accessory structure setbacks are governed by the Philadelphia Zoning Code (Title 14) and vary by zoning district. Use the Philadelphia Atlas at atlas.phila.gov to identify your zoning district and look up the applicable rear yard and side yard setbacks for accessory structures before placing or ordering a shed.

Does adding electricity to my Philadelphia shed require a permit?

Yes. Adding wiring, outlets, lighting, or a subpanel to a shed requires a separate Philadelphia L&I electrical permit and inspection, even when the shed's footprint is 200 square feet or under and otherwise exempt from the building permit requirement.

What foundation does a Philadelphia shed need?

The Philadelphia frost line depth under the PA UCC is 36 inches. Permitted sheds must have footings that comply with PA UCC requirements. Small prefab sheds on treated wood skids or shallow piers are generally acceptable for exempt-sized structures. Site-built sheds over 200 sq ft typically require concrete piers or a full slab extending at least 36 inches below grade. Confirm foundation design before pouring concrete.

How much does a Philadelphia shed permit cost?

Estimated combined fees (building permit + plan review) for a permitted Philadelphia shed typically run $150–$500, plus a small PA state surcharge. Fees are based on project valuation. Verify current amounts through L&I's eCLIPSE portal at eclipse.phila.gov.
