A property that operates under a zoning variance carries hidden complexity that many buyers never investigate. The variance runs with the land, not the owner -- meaning the approval and its attached conditions transfer to you at settlement. A variance that permitted a second unit, a commercial use, or a non-conforming setback can dramatically affect the property's value, your ability to finance it, and your legal obligations as the new owner. This guide explains what variances are, how to find them, and exactly what buyers need to check before closing on a property with ZBA history.
Philadelphia's Zoning Code establishes rules for how every parcel of land can be used and developed -- what uses are permitted, how tall buildings can be, how close to lot lines structures can be placed, how much of a lot can be covered, and how many parking spaces must be provided. When a property owner wants to do something the code does not permit as of right, they can apply to the Zoning Board of Adjustment (ZBA) for relief.
A variance is one form of that relief. It is a formal decision by the ZBA granting the owner permission to deviate from a specific code requirement based on a showing that the strict application of the code would create an undue hardship unique to their property. Variances are not issued routinely; the applicant must meet a legal standard, and the ZBA exercises quasi-judicial authority in deciding whether to grant or deny them.
Two other forms of ZBA relief are sometimes confused with variances. A special exception authorizes a use that the zoning code already allows in that district, but only upon review and approval -- the use is permitted by code but not by right. An appeal of a zoning determination challenges a decision made by the Zoning Administrator, such as a zoning permit denial. Each type of relief has different legal criteria and different implications for how the property can be used going forward.
The type of variance a property holds -- use or dimensional -- has significant implications for financing, future development rights, and what happens if the variance is ever revoked or challenged.
A use variance permits a type of activity on a property that the zoning district does not allow. Examples common in Philadelphia include:
Use variances require the applicant to satisfy the unnecessary hardship standard: the property, because of its unique physical characteristics, cannot be developed or used in conformance with the code without suffering a hardship that is not shared by other similarly zoned properties. This is a high bar, and purely financial hardship -- "I could make more money with the commercial use" -- does not qualify. The hardship must relate to the land itself.
For buyers, a use variance that permitted a second or third unit is the scenario with the highest stakes. If that variance was granted with conditions -- a specific use limitation, a defined number of units, an occupancy restriction -- those conditions follow the property. Violating them exposes the new owner to L&I enforcement action and potential ZBA revocation proceedings.
A dimensional variance permits a deviation from a physical measurement in the zoning code: setback distance from a lot line, maximum building height, minimum lot width, lot coverage percentage, or parking requirement. The use of the property stays within what the district allows; only a measurement is being varied.
Examples in Philadelphia include:
Dimensional variances are generally less legally fragile than use variances because they do not challenge the fundamental character of the use -- they just adjust a measurement. However, they still carry conditions, they still transfer to buyers, and they still affect what you can do with the property in future renovations.
| Variance Type | What It Permits | Legal Standard | Common Philadelphia Examples | Key Buyer Risk |
|---|---|---|---|---|
| Use Variance | A use the zoning district does not allow as of right | Unnecessary hardship unique to the land | Triplex in RSA-5; commercial in residential zone; group care facility | Conditions on unit count or occupancy that restrict future use; potential lender reluctance on non-conforming multi-family |
| Dimensional Variance | A deviation from a physical measurement | Hardship (lower bar than use variance) | Rear addition beyond setback; height limit exceeded; rooftop deck; parking waiver | Conditions attached to specific improvements; limits on further expansion beyond the granted dimensions |
| Special Exception | A conditionally permitted use the code requires ZBA approval for | Compliance with specific criteria in the code for that use type | Day care center; religious institution expansion; auto service in CMX zone | Operating conditions (hours, signage, parking) that bind the buyer as new operator |
| Appeal of Zoning Determination | Reversal of a Zoning Administrator decision | Error of law or fact in the prior determination | Overturning a permit denial; challenging a zoning officer's interpretation of a code section | Outcome reversal on appeal to Court of Common Pleas can retroactively affect the use |
Understanding the ZBA process helps buyers assess how settled a variance is -- and how easily it could be challenged or revoked if conditions are violated.
A variance application is filed through L&I's eCLIPSE system. The filing fee ranges from $150 for minor dimensional variances to $400 or more for use variances and larger development applications. L&I reviews the application for completeness and, if accepted, triggers the Registered Community Organization (RCO) notification process.
Every Philadelphia neighborhood has at least one RCO on record -- a civic association, neighborhood organization, or community development corporation that is formally recognized by the city for zoning input purposes. The applicant is required to notify all RCOs whose territory includes the property and to attend a pre-hearing community meeting if requested. The RCO then submits a formal statement of support, opposition, or conditional support to the ZBA.
The RCO notification period and any required community meeting add at minimum 21 days before the ZBA can schedule a hearing. In practice, many neighborhoods have active RCOs that conduct monthly meetings, which means the next available meeting slot may push the process out 4 to 6 weeks from filing before a hearing date is even assigned.
ZBA hearings are quasi-judicial proceedings conducted by a five-member board. The Zoning Administrator's staff presents a report on the application. The applicant (and usually their attorney) presents testimony, plans, and evidence in support. Neighboring property owners, residents, and the RCO have the right to appear and testify for or against the application. The board then questions all parties and typically deliberates and issues a decision at the hearing, though complex cases may be continued to a subsequent date.
The board can approve the application as filed, approve it with conditions, deny it outright, or continue the hearing to gather additional information. Conditions attached to approvals are binding on the property and all future owners -- they are not personal commitments of the applicant.
| Stage | Typical Duration | Notes |
|---|---|---|
| Application filing and review | 1 to 2 weeks | eCLIPSE submission, completeness review, fee payment |
| RCO notification and community meeting window | 3 to 5 weeks | 21-day minimum; RCO meeting schedule controls the end of this window |
| ZBA scheduling and hearing | 4 to 8 weeks after notification window closes | ZBA calendar; complex or contested cases may require a continuance |
| Decision and written opinion | At hearing or 2 to 4 weeks after | Written decision and resolution required before permits can issue |
| Appeal window | 30 days from decision | Any party can appeal to Philadelphia Court of Common Pleas within 30 days |
| Total: simple uncontested case | 6 to 10 weeks | |
| Total: complex or contested case | 12 to 20 weeks or more | Continuances, RCO opposition, court appeals can extend significantly |
The ZBA frequently grants variances with conditions. These conditions are part of the formal resolution -- the legal document recording the ZBA's decision -- and they are binding on every future owner of the property. Common conditions include:
Unmet conditions are an active problem: A prior owner who received a variance with conditions and never complied with all of them has left you, the buyer, with a property operating in violation of its ZBA approval. L&I can issue an L&I Order tied to the unmet variance condition, and the ZBA can initiate revocation proceedings. Always pull the ZBA resolution, read every condition, and verify compliance with each one before closing.
A variance can add value, subtract value, or create legal complexity that makes the property harder to sell -- depending on what the variance permits, whether it has been exercised, and whether the conditions have been met.
A use variance that legitimizes a multi-family use in a single-family zone is typically the most value-accretive type of zoning variance in Philadelphia. A legally established two-unit or three-unit property in a neighborhood zoned RSA-5 can command a significant premium over a single-family house on the same block, because the buyer acquires the right to collect rental income from additional units that their neighbor cannot legally add without going through the same ZBA process.
For investors, a variance-authorized multi-family building with documented rental history is valued on a gross rent multiplier or cap rate basis rather than the comparable single-family sale approach. This can translate to a $50,000 to $150,000 premium over a single-family property on the same block depending on the neighborhood, condition, and current rental income.
A dimensional variance that authorized a rear addition or above-base-height building likewise preserves value that would be lost if the structure were ever required to be brought into strict conformance. In South Philadelphia and Fishtown neighborhoods where rear additions are common, a property with an existing variance in place for a non-conforming addition is in a better legal position than a property with the same addition but no ZBA history -- the latter may be operating with an entirely unpermitted and non-legal structure.
A variance that authorized a use the current owner has discontinued can create a problem called variance abandonment. Under Pennsylvania zoning law, a variance can be abandoned if the authorized use is discontinued for a substantial period -- typically one to two years. If a prior owner stopped operating the approved commercial use, the variance granting it may no longer be viable, and a buyer who wants to restart that use would need to apply for a new variance. Buyers need to verify not just that a variance exists but that the authorized use is still being actively exercised or that any gap in use falls within the legal protection period.
A conditional variance with unmet conditions can actually reduce value below the baseline -- you have both the burden of the non-conformity and the legal risk of the outstanding violation. For distressed or investor-owned properties with old ZBA approvals from the 1990s or 2000s, it is common to find variance resolutions with detailed conditions that were never fully implemented.
The type and status of a variance directly affect what lenders will and will not underwrite on a property.
Properties with use variances that authorize multi-family use are generally financeable by conventional lenders, FHA, and VA -- as long as the variance is documented, the use is legal non-conforming, and the property meets other underwriting requirements. The key lender requirement is that the authorized use must be able to continue as a legal use, not just a tolerated one. An undocumented or informal two-unit building in an RSA-5 zone with no ZBA approval is a different animal than one with a documented use variance on record.
The specific lender risk question for multi-family variance properties is: if the building burns down or is destroyed, can it be rebuilt to the same configuration? For properties where the use variance authorizes a density above what would be permitted as of right, many lenders -- particularly Fannie Mae conforming lenders -- require that the existing use represent at least 50% of the gross living area or that it qualifies as a legal non-conforming use under state and local law. If it does not, the lender may treat the property as a single-family home for underwriting purposes even if it is currently operating as a two-unit, which affects the income the borrower can use to qualify.
FHA lenders follow Handbook 4000.1 guidelines for legal non-conforming properties. A property is acceptable for FHA financing if it meets three criteria: the use is legal under local zoning; it could be rebuilt to the same configuration without requiring a new variance if destroyed; and the existing improvements are permitted or have been granted legal non-conforming status. A property with a documented use variance in an RSA-5 zone for a two-unit building generally satisfies these criteria. A property with no ZBA record operating as an unpermitted two-unit does not.
VA appraisers and underwriters apply similar analysis. VA MPRs (Minimum Property Requirements) require that the property comply with applicable zoning and building codes or have legal non-conforming status. An undocumented illegal conversion is not compliant; a properly granted and exercised use variance generally is.
For multi-family variance properties, the appraisal approach matters. An FHA or conventional appraisal on a triplex that received a use variance will value the property on an income approach using comparable multi-family sales. The appraiser must confirm the legal status of the units by reviewing the ZBA resolution, the rental license history through eCLIPSE, and the OPA property record. Discrepancies between the OPA unit count and the actual unit count (a common issue when units were added without updating OPA records) can create appraisal conditions that must be resolved before the loan can close.
OPA unit count vs. actual units: Many Philadelphia properties with historical use variances have OPA records that do not match the actual unit count -- particularly in rowhouse neighborhoods where attic conversions and basement units were added decades ago. If your appraisal notes a discrepancy between the OPA designation and the physical property, expect the underwriter to ask for documentation of the ZBA approval before issuing a clear to close. Pull the ZBA resolution before going under contract if the property shows multi-unit characteristics in a single-family zone. See our Philadelphia zoning codes guide for the full district-by-district breakdown.
There is no single publicly accessible database that displays all ZBA approvals for Philadelphia properties the way Atlas displays L&I violations or OPA displays tax records. Finding complete variance history requires checking multiple sources.
Go to atlas.phila.gov and search the property address. The Zoning tab will show the base zoning district, any overlay districts, and the OPA-recorded property use designation. If the OPA designation shows a multi-family use type in a single-family zone, that is a strong indicator of a prior ZBA approval that should be investigated further. Atlas does not display ZBA case history directly, but the property record may include links to permit records associated with ZBA approvals.
The ZBA maintains records of decisions going back decades. You can search the ZBA docket by address or parcel number by contacting the ZBA directly at (215) 686-2500 or visiting their office at 1515 Arch Street, 18th Floor. The ZBA website at phila.gov also provides access to ZBA calendar items and some older decisions. For properties in neighborhoods with active development histories, calling the ZBA and asking whether any resolution exists for the address is the most reliable method.
L&I's eCLIPSE system at eclipse.phila.gov maintains permit records that are often linked to ZBA approvals. A permitted addition, conversion, or change-of-use associated with a ZBA approval will have a permit record that references the ZBA resolution number. Search the property address in eCLIPSE and look for permit records with notes referencing "ZBA" or "variance" in the permit description or conditions.
Under the Pennsylvania Real Estate Seller Disclosure Law (RESDL), a seller is required to disclose any known zoning violations, including any ZBA case history they are aware of. Ask directly in writing whether the property has been before the ZBA, whether any variance or special exception exists, and whether all conditions of any approval have been satisfied. The seller's answer -- and the documentation they provide or fail to provide -- will shape your pre-closing due diligence. See our Pennsylvania seller disclosure guide for the full RESDL framework.
An unmet ZBA condition is an active violation of the variance approval. The consequences depend on how the condition is framed in the resolution, how long it has been unmet, and whether L&I or the ZBA has taken notice.
L&I enforcement: If the unmet condition involves a physical characteristic of the property -- required landscaping that was never installed, a required parking space that was never constructed, a unit that was supposed to be removed but was not -- L&I can issue a Violation Order requiring compliance with the variance condition as a code enforcement matter. This Order transfers to the buyer at settlement the same way any other L&I Order does.
ZBA revocation proceedings: The ZBA has authority to initiate revocation proceedings for variances where conditions have been materially violated. Revocation proceedings are public hearings, and a successful revocation can eliminate the property's right to the authorized non-conforming use entirely. This is most commonly triggered by complaints from neighbors or an L&I enforcement referral.
Title insurance gaps: Most title insurance policies exclude coverage for zoning violations and unmet variance conditions as Schedule B exceptions. The title company will note the existing zoning designation and may note any known ZBA history, but the buyer takes subject to those conditions at closing. Title insurance provides no remedy if a prior owner violated a variance condition and the use is revoked post-closing.
Financing complications post-closing: If you acquire a property relying on a variance-authorized income stream -- a legal duplex in a single-family zone -- and the variance is later revoked due to unmet conditions, your lender's security interest is potentially impaired. Some loan covenants require notification of material changes to legal use status.

For experienced Philadelphia investors, documented variance-authorized multi-family properties are often the most desirable acquisitions in rowhouse neighborhoods. A properly documented two-unit or three-unit in a Fishtown, Kensington, or South Philly RSA-5 block carries inherent scarcity value -- neighboring owners cannot simply build a competing unit without going through the same ZBA process that may or may not succeed.
The investor due diligence framework for these properties is not fundamentally different from the checklist above, but the emphasis shifts. The priority questions are:
A variance-authorized multi-family property with clean documentation -- current rental licenses, OPA unit count matching ZBA authorization, no open L&I Orders, eCLIPSE permits linked to the ZBA resolution -- is a low-risk acquisition. The same property with a 25-year-old ZBA resolution, no linked permits, and an OPA record showing a different unit count than what physically exists requires a legal opinion before committing capital. See our Philadelphia multi-family investing guide for the full due diligence framework on duplex and triplex acquisitions.
Yes. A ZBA-approved variance runs with the land, not with the person who applied for it. When you buy a property that received a variance, you acquire both the benefit of the approval -- the right to maintain the non-conforming use or structure -- and any conditions the ZBA attached to that approval. If a prior owner received a variance subject to conditions that were never met, those unmet conditions follow the property to you.
A use variance permits a use of the property that the zoning code would not normally allow in that district -- for example, a commercial use in a residential zone or a multi-family building on a lot zoned for single-family use. A dimensional variance permits a deviation from a physical standard -- setback, lot coverage, height, lot size, or parking -- while keeping the use within what the district allows. Use variances require the applicant to satisfy the unnecessary hardship standard, which is a higher legal hurdle than the criteria applied to dimensional variances.
From filing to a final decision typically takes 6 to 16 weeks depending on case complexity, RCO engagement, and ZBA scheduling. Filing an application in eCLIPSE triggers the RCO notification process, which adds 21 days before a hearing date can be set. The ZBA typically schedules hearings 4 to 8 weeks after the notification period closes. Simple cases may be decided at the first hearing; complex or contested cases requiring continuances can extend the total timeline to 4 to 6 months.
Search the property address in Atlas at atlas.phila.gov and look at the Zoning tab, which will show the base zoning district and any overlay districts. For ZBA case history, contact the Philadelphia ZBA directly at (215) 686-2500 or search eCLIPSE at eclipse.phila.gov for permit records referencing a ZBA resolution. The Pennsylvania Seller Disclosure Law requires sellers to disclose known ZBA cases, so always ask directly in writing as part of your pre-offer due diligence.
