Permits

BUILDING/DEMOLITION PERMITS – RESIDENTIAL

The purpose of a building permit is to ensure safe, quality construction which protects the public health, safety, and welfare of our residents. The permit process confirms that all standards are met with appropriate materials. Any new construction and remodeling projects require a township building permit.

Construction under 1,000 square feet does not require an inspection providing it is stand-alone. If attached to a larger construction (house, garage, etc.) inspection is required.

New construction requires a series of five (5) inspections throughout the building process, plus an electrical inspection.

Permits from the township are $25. Any questions, please call the township office at 724-735-2705.

ON-LOT SEWER DISPOSAL SYSTEMS

PRIVATE ON-LOT SEWAGE DISPOSAL SYSTEMS

New construction outside of the PSDS (Public Sewer Disposal System) requires a perc test for an on-lot sewer disposal system. This testing determines if the property is capable of the required processing.

Below is the Township Sewage Enforcement Officer, phone number, and application testing and permit pricing. Also listed is a notice from the DEP on “Understanding Septic Systems” for a clearer picture of what is necessary to proceed.

Any questions, please call the township office at 724-735-2705.
