Bathroom renovations in Philadelphia may also involve lots of electrical work, which typically requires a permit.

Adding New Electrical Circuits

You will need an electrical permit if your bathroom renovation plan involves adding new electrical circuits to prevent overloads caused by high-power devices used in bathrooms, such as hair dryers and towel heaters.

Removing Walls

If you want to expand your primary bathroom and remove walls to do so, you need to get a general building permit in Philadelphia. Permits prevent homeowners from removing or moving load-bearing walls during renovations, thereby risking the home’s structural integrity.

Constructing Walls

Constructing a wall to change your home’s floor plan and expand the size of your primary bathroom is also only allowed once you get a permit and your plans are approved. Even if there are no structural implications, you may need approval before constructing new walls in Philadelphia.

Moving doorways in a house alters its interior framing, so a general building permit is required before you do this during a bathroom renovation in Philadelphia.

Moving or installing ducts, replacing or upgrading equipment, and other significant HVAC work require a specific mechanical permit. If the renovation includes expanding the bathroom, HVAC work may be needed to maintain comfortable temperatures in the larger space.
