Philadelphia Building Permits

The short version

• L&I is the permit authority. The Department of Licenses and Inspections issues building permits, zoning permits, trade permits (plumbing, electrical), and business licenses.
• eCLIPSE is the online portal. Most applications, tracking, and design-professional registration go through eCLIPSE — in-person filing at the Municipal Services Building (MSB) is a backup.
• Pre-L&I approvals are mandatory. Before L&I will accept a permit application, you typically need: a Streets Department job number, stamped City Planning Commission plans (for many projects), and Public Health permit (for relevant projects).
• Zoning permit usually before building permit. Most significant commercial projects need zoning review and permit before the building permit process starts.
• I-Codes are adopted with local amendments. Philadelphia is transitioning to the 2021 I-Codes effective July 2026 — permits after July 1, 2026 must comply with the new edition.

Where to go — primary sources

• Philadelphia L&I — primary department site.
• Get a Building Permit — application portal and requirements.
• Construction and Repair Permits — authoritative construction permits hub.
• eCLIPSE — online portal for permit applications, tracking, and design professional registration.
• Apply for a Permit (zoning) — zoning permit gateway.

Permit types L&I issues

• Building permits — construction, repair, enlargement, alteration, demolition.
• EZ permits — simpler process for minor work that doesn't require plan review.
• Zoning permits — new construction / additions, change-of-use, use-by-right / variance.
• Plumbing permits — for plumbing trade work.
• Electrical permits — for electrical trade work.
• Make Safe permits — for dangerous-building stabilization.
• Trade and business licenses — required for contractors operating in the city.
• Administrative / operations permits — for specific ongoing activities.

Pre-L&I approvals — the sequence that trips out-of-state contractors

L&I will not accept a permit application without certain pre-approvals from other City departments in hand. Missing any of these means the application gets rejected at intake. The most commonly required:

• Streets Department job number. Required for most construction in the public right-of-way or where street access / protection is affected. Obtain the job number from the Streets Department before filing with L&I.
• Stamped City Planning Commission plans. For projects subject to Planning Commission review, plans must be stamped by the Planning Commission before L&I will accept them.
• Public Health permits. For projects involving food service, child care, specific residential occupancies, or regulated operations, Health Department permit or approval may be required upstream.
• Water Department approvals. For new service connections or significant modifications to water / sewer infrastructure.
• Fire Department plan review. For certain occupancies and project types.

Proofs of these approvals are submitted at the Permit and License Center in the Municipal Services Building (MSB), 1401 John F. Kennedy Blvd. Electronic submission through eCLIPSE has reduced some in-person requirements, but physical submission of stamped approvals remains common for non-EZ permits.

Zoning-first for significant commercial work

Philadelphia's zoning code (Title 14) determines use-by-right vs. conditional use vs. variance. For significant commercial projects, the typical sequence:

1. Zoning review: confirm use-by-right or apply for zoning permit.
2. For variances or conditional uses: Zoning Board of Adjustment (ZBA) process, which adds weeks-to-months.
3. Once zoning is cleared: obtain pre-L&I approvals (Streets, Planning Commission, Public Health).
4. Apply for building permit through eCLIPSE.
5. L&I plan review.
6. Permit issuance; trade permits can then be obtained.
7. Construction.
8. Final inspections; Certificate of Occupancy.

I-Code adoption and the July 2026 transition

Philadelphia adopts the International Codes (IBC, IMC, IPC, IEC, IFC) with Pennsylvania Uniform Construction Code (UCC) baseline plus local amendments. Philadelphia is transitioning to the 2021 I-Codes effective July 1, 2026 — permit applications submitted on or after that date must comply with the 2021 editions.

For projects straddling the transition date, expect:

• Applications submitted before July 1, 2026 may be reviewed under the prior code edition (verify vested-rights policy with L&I).
• Permit extensions, revisions, and change orders on in-progress projects may be affected by the transition.
• Design teams should know which edition applies before committing design direction.

MEP-specific considerations for Philadelphia work

• Trade licensing is Philadelphia-specific. L&I licenses electricians and plumbers for Philadelphia work — a PA state trade license is not sufficient; Philadelphia has its own licensure.
• Separate trade permits. Plumbing, electrical, mechanical trade permits are separately issued; coordinate application timing with the main building permit.
• Energy code. Philadelphia's energy code is aligned with IECC as adopted via PA UCC plus city amendments; larger buildings may also have benchmarking obligations under Philadelphia's building energy-performance program.
• Historical buildings. Properties in historic districts or certified historic have additional Historic Commission review layered on top of L&I process.

Common pitfalls

• Filing L&I application without Streets Department job number — application rejected at intake.
• Missing Planning Commission stamp on plans for projects that require it.
• Skipping zoning review for projects that need zoning-first.
• Assuming a PA state trade license works for Philadelphia trade work — it doesn't.
• Not planning for the historic commission layer on properties in historic districts.
• Under-estimating the eCLIPSE learning curve for first-time users.

The practical workflow

1. Confirm zoning: use-by-right, conditional, or variance.
2. If historic property: engage Historic Commission early.
3. Identify pre-L&I approvals needed (Streets, Planning, Public Health, Water, Fire).
4. Obtain each pre-approval before filing L&I application.
5. Register design professional in eCLIPSE (if not already).
6. Submit building permit application via eCLIPSE; upload stamped plans + pre-approvals.
7. Address L&I plan review comments.
8. Permit issuance; trade permits follow for plumbing / electrical / mechanical.
9. Construct per approved plans.
10. Schedule inspections via eCLIPSE; pass final inspections.
11. Certificate of Occupancy (CO) issued.

When to get direct help

For project-specific pre-approval sequencing, L&I publishes the required checklist on the construction permits page. For zoning questions (especially variance or conditional-use), engage a Philadelphia zoning professional or attorney experienced with the ZBA. For historic properties, engage a Historic Commission consultant early.

Why we built this

Philadelphia L&I catches out-of-state contractors in one recurring way: the pre-L&I approvals from other City departments. An application that looks complete to a contractor in Wilmington or Camden gets rejected at intake in Philadelphia because it's missing a Streets Department job number or Planning Commission stamp. This page surfaces the sequencing up front so projects don't lose weeks at intake.
