Filing a lot line adjustment in Philadelphia, Pennsylvania requires coordinating zoning, surveying, and recording steps with city offices. This guide explains who enforces lot line changes, what documents are typically required, and practical action steps to prepare a plan, secure approvals, and record the revised deeds. Read each step, gather a survey and deeds, check zoning constraints, and contact the responsible city offices early to avoid corrections and delays.

Overview

A lot line adjustment moves the legal boundary between two or more adjacent parcels without creating new lots. In Philadelphia the process typically involves a licensed surveyor, review for zoning and subdivision compliance, and recording revised deeds or plans with the City. Whether a proposed adjustment requires subdivision approval depends on zoning and land-development rules; contact city planning or L&I for confirmation.

Preparing your application

Before filing, gather key documents and confirm requirements with city reviewers.

  • Licensed boundary survey or record plan prepared by a surveyor.
  • Existing deeds and legal descriptions for each parcel.
  • Zoning lot review and confirmation whether subdivision/land-development approval is required; consult the City Planning Commission.City Planning guidance[1]
  • Determine whether a record plan or subdivision application must be filed with Licenses & Inspections and recorded with the Department of Records.
  • Check timelines with reviewers; plan for survey drafting, agency review, and recording.
Start with a licensed surveyor to avoid rework during city review.

Where to file and who enforces

The principal city offices involved are the Department of Licenses and Inspections (L&I) for plan review and permits, the City Planning Commission for subdivision and land-development determinations, and the Department of Records for recording deeds and plans. Contact L&I for filing instructions and inspections; L&I enforces compliance with building, zoning, and plan approval conditions.L&I land development[2]

Penalties & Enforcement

Enforcement is handled by Licenses & Inspections; remedies may include fines, stop-work orders, or orders to restore legal boundaries. Specific fine amounts, escalation, and time limits are not consistently published on a single city page; where amounts or schedules appear they are listed on the enforcing agency page or the municipal code.

  • Fine amounts: not specified on the cited page.[2]
  • Escalation: first or continuing offence details not specified on the cited page.
  • Non-monetary sanctions: stop-work or corrective orders, permit denial, and potential court actions enforced by L&I.
  • Inspection and complaint pathways: report potential unlawful lot changes to L&I using the department contact methods; see L&I land-development contact pages.[2]
  • Appeals and review: permit and enforcement decisions may be appealed to the Board of License and Inspection Review or other designated appeal boards; check appeal time limits with L&I as the city pages do not consistently list deadlines.
If you receive an enforcement notice act quickly and contact L&I to understand appeal deadlines.
