The distinctive decision question in this ZIP market is whether the current broad asking-rent reference can be used responsibly beside household and inventory signals, without mistaking any aggregate for the terms of a particular home. In June 2026, Zillow’s ZIP-level ZORI is $1,523 per month, up 3.39% from a year earlier. This five-digit ZIP label is both Zillow’s ZIP market identifier and the match to a Census ZCTA; a ZCTA is a statistical area and is not identical to a USPS delivery ZIP. ZORI is a typical observed asking-rent index blended across rental types. It is therefore a current market reference, not a record of a property’s bedroom count, physical attributes, included utilities, mandatory charges, or lease terms.
Household measures place that reference beside a different evidence universe rather than supplying a tenant test. The ACS 2024 5-year ZCTA survey reports median household income of $43,244. Annualizing the ZIP index puts it at 42.3% of that median income, a comparison that neither identifies a renter’s earnings nor describes an actual payment. At a 30% rent-to-income screen, $1,523 per month corresponds arithmetically to $60,920 in annual income. This screen is arithmetic only, not advice and not an applicant qualification rule. Of 28,654 occupied housing units, 15,261 are renter occupied, or 53.3%. ACS reports 8,987 renter households, or 58.9% of renter households, with reported rent burdens at or above that threshold. This observed aggregate describes renter households in the survey, not a particular unit or lease.
Rent measures should not be merged. The same ACS survey puts median gross rent at $1,444; it is a five-year survey measure of occupied renter homes and includes selected utilities. The $1,523 June Zillow index is $79, or 5.5%, above that ACS median, but this difference is descriptive, not a measure of change in a common universe. The local FY2026 HUD FMR/SAFMR two-bedroom standard is $1,520, placing ZORI 0.2% higher. HUD FMR/SAFMR is an administrative, bedroom-specific standard rather than asking rent. Its proximity to ZORI does not establish a market rent for a two-bedroom property, validate an advertised price, or make the HUD standard and Zillow index interchangeable.
The supplied bedroom view is deliberately modelled, not observed. It scales ZIP ZORI through the local HUD ladder to estimate $1,172 for a studio, $1,283 for one bedroom, $1,523 for two bedrooms, $1,824 for three bedrooms, and $2,034 for four bedrooms each month. The underlying HUD ladder runs from $1,170 for a studio to $2,030 for four bedrooms. That pattern shows the relative bedroom scaling embedded in the model; it is not a measured series of bedroom rents. In particular, the match between the modelled two-bedroom figure and ZORI is a construction result, not confirmation that all two-bedroom listings ask that amount.
Housing stock and vacancy data give composition, not unit-level availability. The ZCTA contains 32,744 housing units, with 4,090 vacant, a 12.5% vacancy rate. Among vacancies, 1,213 are designated for rent and 243 for sale; no seasonal vacancies are recorded. Structure classifications count 23,425 single-family units and 1,993 units in large multifamily structures, with the balance in other classifications. These categories neither reveal an advertised rent nor indicate that a vacancy is leasable now, suitable for a given household, or comparable with the blended Zillow index. They also do not indicate the bedroom mix of currently available units.
Broader benchmarks point in a different direction but remain context only. At the City of Philadelphia scope, the rent context is about $1,814, above the ZIP index. At Philadelphia County scope, the rent context is $1,814 and the two-bedroom HUD standard is $1,810. At the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD metro scope, rent context is $1,928, apartment vacancy is 5.4%, and apartment time on market is 27 days. The city, county, and metro values describe wider geographic scopes, not ZIP conditions, and their rent measures, standards, and apartment metrics should not substitute for a local listing’s terms.
Important limits remain. Zillow is a blended ZIP asking-rent index, ACS is a survey estimate with sampling uncertainty and a different reference period, and HUD figures are administrative standards. The ZCTA-to-delivery-ZIP distinction further limits exact geographic matching. For any property-level decision, verify the advertised base rent, actual bedroom count, availability date, lease duration, included or separately billed utilities, and every required recurring charge. Establish the tenant-paid monthly total before comparing it with any reference. Also confirm the property’s listed geography and avoid inferring availability, rent burden, rent level, or suitability from an index, a survey aggregate, a HUD standard, a vacancy category, or city, county, and metro context.
