Reading this house's deeds, permits and assessments…

What to do with this

The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.

If you’re buying

Built 1915: lead rules apply

Federal law requires a lead-paint disclosure at sale for any pre-1978 home. If it will be rented, Philadelphia also requires a lead-safe or lead-free certificate before a rental license can issue.

If you own it

Construction next door (1927 Diamond St, 2024)

Excavation deeper than 5 feet, or within 10 feet of an adjacent structure, legally requires the developer to survey neighboring homes first and give owners 10 days' written notice. Insist on the pre-construction survey — it is your evidence if cracks appear.

If you’re the landlord

Lead certificate is not optional

Built 1915: every rental unit needs a lead-safe or lead-free certificate on file with the City. Without one: fines up to $2,000/day per unit, tenants may withhold rent, courts can order rent refunded — and no eviction will stand.

Licensed rental — keep it that way

Renewal requires city tax clearance and zero open L&I violations on the property. A lapsed license suspends the right to collect rent or evict.

Derived from this house's public records and the city's rules as of 2026 (abatement ordinance, Homestead, rental licensing, lead certification, L&I process, excavation protections). Informational only — not legal, tax, or investment advice.

The investment read

How this house has moved and where it's pointed: the city's assessed value (not a listing price) over 12 years, charted against its block; appreciation is that history's pace, and the 5-year figure simply extends it. Yield estimates rent-vs-price from area rents. Ask the analyst below to dig into any number.
