Property risk in Parkwood — Far Northeast Philadelphia — what buyers need to know

Parkwood occupies the northern section of ZIP 19116 in Far Northeast Philadelphia, bounded by the Pennsylvania Turnpike to the north, Bustleton Avenue to the west, and the Pennypack Creek corridor to the south and east. The neighborhood was developed primarily between 1960 and 1975 as a wave of suburban-style construction within the city limits — detached single-family homes with driveways, attached or detached garages, front lawns, and rear yards large enough for pools and decks. This construction era and lot configuration creates a specific set of risk factors that differ meaningfully from the older rowhouse and twin stock found in much of Philadelphia: buried oil tanks in a significant portion of pre-1975 homes, a long history of unpermitted accessory improvements (pools, decks, finished basements), garage conversions completed without proper permits, and mechanical systems now 50–65 years old. The neighborhood itself is generally stable and well-maintained, but buyers who approach these homes without evaluating these specific risk categories can encounter significant post-closing expenses.

Buried oil tanks in pre-1975 homes

Parkwood's 1960–1975 development window means that a substantial portion of homes were originally built with oil heat. Fuel oil storage tanks were typically buried in the rear yard or installed beneath the garage floor:

• Look for conversion evidence at every pre-1975 home. A converted oil system leaves evidence: an abandoned fill pipe capped on the exterior wall, a vent pipe on the foundation, or a sealed floor penetration in the basement or garage. The presence of any of these should trigger a tank investigation.
• Check eCLIPSE for a tank removal permit. If a tank was properly removed, the contractor was required to pull a permit. No permit does not mean no tank — many tank removals in Parkwood occurred before permit requirements were consistently enforced. But a removal permit with clearance documentation is the strongest evidence that a tank was properly addressed.
• PA DEP PATS database. Search for the property address in the Pennsylvania Above/Underground Storage Tank registry. Note that residential tanks were often never registered, so a clean result is not conclusive.
• Commission a magnetometry scan when uncertain. A $200–$400 magnetometry sweep of the rear yard and garage slab area can identify buried ferrous objects consistent with a fuel oil tank. If any conversion evidence is present and no removal permit exists, this step is worth the cost before making an offer.
• Contaminated soil remediation exposure. A leaking or degraded tank in Parkwood can generate a petroleum contamination plume in the soil. Remediation costs range from $5,000 for minor surface contamination to $50,000+ for a significant plume. See our underground oil tank guide for the full cost and transaction framework.

Pool, deck, and accessory structure permits

Parkwood's larger lots have accommodated decades of accessory improvements — in-ground and above-ground pools, wood and composite decks, sunrooms, sheds, and finished basement spaces. A significant portion of these improvements were done without permits:

• Philadelphia requires permits for pools, decks, and structural additions. An in-ground pool requires a zoning permit, building permit, and fence/barrier permit. A deck over 30 inches above grade requires a building permit. A sunroom or enclosed addition requires a full permit set. These are not optional — unpermitted improvements are a legal liability that transfers to the buyer at settlement.
• Verify permit status in eCLIPSE. Run the subject property address in eCLIPSE and cross-reference the permit history against visible improvements. A pool with no pool permit on record, a large deck with no deck permit, or a finished basement with no permit for the work is a flag that requires resolution before closing.
• Open permits are a separate problem. An improvement with a permit that was opened but never had a final inspection is an open permit — a legal cloud on the property that can affect resale and refinancing. Confirm that all permits in eCLIPSE show a final inspection or certificate of completion status.
• Setback compliance. Pools and decks built without permits are frequently located closer to property lines than zoning allows. A post-purchase L&I inspection or neighbor complaint can result in a notice to abate — requiring removal or reconstruction at the current owner's expense. If an unpermitted pool or deck is close to a fence line, verify setback compliance before proceeding.

Garage conversions and finished basements

Parkwood's attached garages have frequently been converted to additional living space — family rooms, offices, or in-law suites — and below-grade basements have been finished to add habitable square footage. Both are common sources of unpermitted work:

• A converted garage used as habitable space requires a permit. Garage-to-living-space conversions require a building permit covering structural modifications (wall insulation, floor, windows), HVAC (the converted space needs heat and ventilation), and electrical (outlets, lighting, egress). A conversion done without permits is not legally habitable space and may affect the property's OPA classification and assessed value.
• Egress compliance for below-grade spaces. A finished basement used as a bedroom or sleeping space requires an egress window meeting minimum size requirements. If the basement bedroom has only a small high window that does not meet egress code, the space is not legally usable as a sleeping room. Commission a U&O certificate inspection — Philadelphia requires one for sales of residential properties — and note any deficiencies called out in the inspection report.
• Waterproofing and moisture in finished basements. In Parkwood, as throughout the Northeast, basement moisture is a recurring issue in finished spaces. A finished basement that shows no visible moisture problems during a dry-season inspection may have experienced and concealed prior water intrusion. Check for efflorescence (white mineral deposits) on foundation walls, sump pump installation and pit condition, and any evidence of prior remediation or paneling installed to conceal moisture-damaged walls.

Aging mechanical systems

Parkwood homes built between 1960 and 1975 have core mechanical systems that are now 50–65 years old. Even homes that received system replacements in the 1990s are now running on 25–35 year-old replacements approaching end of life:

• HVAC evaluation by a licensed contractor. A forced-air heating and cooling system more than 20 years old should be evaluated by a licensed HVAC contractor — not just visually inspected by a home inspector — before purchase. Heat exchanger cracks, refrigerant leaks, and blower motor condition require contractor-level diagnostics to assess accurately.
• Electrical panel and service. Many Parkwood homes retain original 100-amp service panels. While 100-amp service is adequate for homes without electric heat or electric vehicle charging, homeowners adding modern loads — heat pumps, EV chargers, induction cooking — will need a service upgrade. Commission an electrician's assessment if an upgrade is anticipated.
• Water heater and plumbing. Original copper plumbing is typically in good condition in Parkwood homes. Water heaters and any supply-side repairs done with CPVC or PEX should be evaluated for age and condition during inspection.

What to check on every Parkwood property

1. Oil tank investigation. PA DEP PATS search + eCLIPSE removal permit check + visual inspection for conversion evidence. Commission magnetometry scan if any conversion evidence is found and no removal permit exists.
2. Full permit history in eCLIPSE. Cross-reference every visible improvement (pool, deck, addition, conversion) against permit records. Identify any open or unpermitted work.
3. U&O certificate inspection. Required for all residential sales in Philadelphia. Note any deficiencies called out in the inspection report.
4. HVAC evaluation by a licensed contractor. Age, condition, heat exchanger integrity, refrigerant status.
5. Electrical panel inspection. Panel brand, amperage, condition. Check for Federal Pacific or Zinsco panels — replace regardless of condition.
6. Basement moisture evaluation. Sump pump condition, efflorescence, evidence of prior water intrusion in finished spaces.
7. Municipal lien certificate. Tax balance, PWD account status, L&I liens.
8. Lead paint assessment if pre-1978. All Parkwood homes built before 1978 contain lead paint.
