#67 of 67 in Pennsylvania

Philadelphia County, Pennsylvania requires a building permit for new construction, enlargement, alteration, demolition, occupancy changes, major repairs and qualifying earth disturbance1. The Department of Licenses and Inspections (L&I) handles building permits, required inspections and citywide zoning23. Permit exceptions and the owner-builder option are narrow, so confirm the project scope before work starts14.

Do you need a building permit in Philadelphia County, Pennsylvania?

Yes. Philadelphia County requires a building permit for new construction, enlargement, alteration, demolition, occupancy changes, major repairs and earth disturbance of 5,000 square feet or more1. Listed exceptions include regular maintenance, fences no taller than six feet, retaining walls no taller than two feet, some exterior work, masonry pointing, replacement doors and windows in one- or two-family dwellings, and interior finish work1. Floodplain properties may need special documents or a review meeting, and L&I will not release a new-construction permit unless City taxes on the property are current1. Pennsylvania's Uniform Construction Code also applies to building construction in the county10.

Who is the Philadelphia County building department, and how do you reach them?

Building permits for Philadelphia County go through the Department of Licenses and Inspections (L&I), which also handles zoning, licensing and code enforcement11. Reach L&I at (215) 686-8686 or through 311, or visit 1401 John F. Kennedy Blvd., 11th Floor, Philadelphia, PA 1910211. The permit tells the contractor which inspections are required; inspections can be scheduled through eCLIPSE or by telephone, and L&I issues a Certificate of Approval after all required inspections are completed successfully2. After-hours inspections must be initiated at least two business days ahead and cost $240 for the first four hours plus $60 for each additional hour2.

Does Philadelphia County have zoning?

Yes. The Philadelphia Zoning Code regulates development and changes of use throughout Philadelphia County3. Zoning rules cover land use, building height and bulk, population density, parking, signs, private-property development, protected areas and steep slopes; height requirements vary by base district and overlay5. Start with Atlas to identify the property's zoning district, then use the Zoning Quick Reference Guide, Zoning Summary Generator and Philadelphia Zoning Code to identify the district-specific rules and approvals9. L&I issues zoning permits and can be reached at (215) 686-8686 or 31112. The available material does not establish one countywide minimum dwelling size, lot-coverage rule or accessory-dwelling answer, so ask L&I about the exact parcel and proposal12.

How do septic and sewer rules work in Philadelphia County?

Philadelphia is served by public sewer through the Philadelphia Water Department (PWD)6. A PWD connection permit is required to install or repair a water service or sewer lateral from PWD infrastructure to the property7. New connections require project and design information before permitting, followed by the required inspections or installations after permits are issued7. For an unusual parcel proposing an on-lot system, Pennsylvania generally requires a local-agency permit before installation, construction, occupancy or use, subject to narrow exceptions13. We could not confirm which agency administers an on-lot sewage application in Philadelphia County, so establish the responsible agency before relying on a septic design or state-law exception. The soil survey estimates that 68.8% of county soils lack severe limitations for a conventional drain field, but parcel testing and an identified permitting authority still matter14.

Can you live in an RV or tiny home on your land in Philadelphia County?

We could not confirm a Philadelphia County rule allowing residential use of an RV or tiny home on a private lot. The Philadelphia Zoning Code regulates development and changes of use countywide, and district-specific rules apply to each property39. Ask L&I whether the proposed vehicle or structure, occupancy, duration and utility arrangement are allowed in the parcel's district before buying or moving anything onto the site12. A federally labeled manufactured home installed to its approved design receives limited treatment under Pennsylvania's construction code, but additions, later alterations, relocation, certain utility connections and grading can bring the UCC into play15. That state construction rule does not decide whether Philadelphia zoning allows the home on a particular lot153.

Building in Philadelphia County: the steps, in order

  1. Use Atlas and the City's zoning resources to identify the district, overlays and approvals that apply to the parcel9.
  2. Confirm with L&I whether the work needs zoning approval, a building permit, floodplain documents or a review meeting31.
  3. Apply through L&I and name every applicable contractor before final permit payment; contractors must be licensed, insured and current on taxes4.
  4. A resident owner may perform eligible work on an existing one- or two-family home only when the project does not require an electrical or plumbing permit4.
  5. Schedule every inspection identified on the permit and obtain the Certificate of Approval after successful completion2.
  6. Determine whether the project receives a certificate of occupancy through its building permit or needs a separate application8.
  7. Obtain PWD permits before installing or repairing water services or sewer laterals7.

What to check before you buy land in Philadelphia County

Check the parcel's zoning district and overlays before evaluating buildable area, because permitted use, height and bulk are district-specific95. Confirm whether the title, proposed occupancy and existing structures match City records, since an occupancy change can trigger a building permit and sometimes a certificate of occupancy18. Verify that City taxes are current before planning new construction, because L&I will not release a new-construction permit on a property with delinquent City taxes1. Confirm water and sewer connection conditions with PWD, and do not assume an on-lot sewage option is available76. If access touches state highway land or a PennDOT drainage facility, a PennDOT Highway Occupancy Permit is required16. The effective property tax rate is about 0.8%, and the median annual property tax bill is about $1,9521718.

Watch-outs

  • A building-permit exception does not override zoning, floodplain or trade-permit requirements; have L&I confirm the complete approval path for the proposed work111.
  • A certificate of occupancy is tied to specified projects and occupancy changes, not every existing home; a separate application and fee may apply when no building permit produces the certificate819.
  • We could not confirm parcel-level rules for RV occupancy, tiny homes, minimum dwelling size or private wells; ask L&I about land use and the appropriate agency about water before buying12.
