L&I — Licenses and Inspections — is Philadelphia's building department and one of the most discussed topics in the city's renovation community. It has a reputation for slow turnaround and inconsistent inspectors, and while some of that reputation is earned, the process is far more manageable once you understand how it works.
The first thing to know is that most residential renovation permits in Philadelphia are obtained over the counter in a single visit, same day or next day. A simple interior renovation — flooring, kitchen refresh, bathroom remodel that doesn't move walls or relocate plumbing stacks — typically qualifies for an over-the-counter electrical and plumbing permit. These are fast and predictable.
When plan review is required
Projects that require plan review — anything structural, additions, changes to the building envelope, load-bearing wall removal — go into the review queue. That queue is where the reputation is made. As of 2026, plan review for residential projects is running 6 to 10 weeks from submission to approval. There are ways to reduce that: a complete, properly formatted submission the first time eliminates the back-and-forth corrections that are the actual source of most delays. We have filed hundreds of L&I applications, and a well-prepared package gets through measurably faster than one with gaps.
Permit cost is based on project value — typically 1.5% to 2% for residential work. On a $60,000 kitchen renovation, expect $900 to $1,200 in permit fees. That cost is real but not negotiable, and any GC who suggests "skipping the permit to save money" is transferring legal and financial risk entirely onto you as the homeowner.
Why permits matter for your investment
Unpermitted work creates three problems that outweigh any short-term savings. First, homeowner's insurance does not cover damage arising from unpermitted work. Second, unpermitted alterations must be disclosed at sale, and buyers' inspectors find them. Third — and most important in Philly — the city can require you to expose and remediate unpermitted work regardless of when it was done. We have seen homeowners spend more undoing unpermitted work than the original permitted job would have cost.
The honest truth about L&I is that the inspectors are generally looking for the same things you are: a building that is safe, structurally sound, and correctly wired and plumbed. A GC who knows the code and builds to it has nothing to fear from an inspection — and neither does the homeowner who hired them.
