Philadelphia Rowhouse Renovation — What You Need to Know Before You Start

← Back to Philadelphia Remodeling Guide

Philadelphia rowhouses are some of the most charming homes in the country — and some of the most challenging to renovate. If you own a rowhouse in South Philly, Fishtown, Northern Liberties, or anywhere else in the city, this guide covers what to expect before, during, and after your renovation.

The age factor

Most Philadelphia rowhouses were built between the 1880s and the 1950s. That means older plumbing — often galvanized steel pipes that corrode from the inside — and knob-and-tube or early aluminum wiring that does not meet modern code. When we renovate a rowhouse kitchen or bathroom, we almost always encounter plumbing or electrical work that needs to be updated. We build this reality into our estimates upfront so it does not catch you off guard.

Narrow layouts and limited access

Rowhouses are narrow by design — typically 14 to 18 feet wide. This affects how materials are delivered, how debris is removed, and how trades work inside the space. An experienced Philadelphia contractor accounts for this in the schedule and the budget. A contractor who is new to rowhouse work often does not — and you pay for their learning curve.

Philadelphia permits — what you need to know

The City of Philadelphia requires permits for virtually any structural, plumbing, or electrical work. Pulling permits protects you as a homeowner — it means the work is inspected and meets code. Some contractors skip permits to move faster and charge less. This creates problems when you sell your home and a buyer's inspector finds unpermitted work. At Oz Remodeling we pull all required permits on every project.

Party walls

Rowhouses share walls with their neighbors — called party walls. Any work that involves or could affect a party wall requires careful planning and in some cases notification to your neighbors. This is something most homeowners do not think about until it becomes an issue mid-project.
