Does Upper Allen Township have zoning?

Yes. Upper Allen Township has its own zoning chapter, Chapter 245 of the township code¹. It sorts land into low-, medium- and high-density residential districts, plus agriculture, commercial and mixed-use, industrial and steep-slope overlay districts⁶. Cumberland County does not administer zoning; its own page says zoning regulations are established and administered by the municipalities⁴. A zoning permit is required for interior and exterior improvements¹³.

Setbacks, lot sizes, minimum home sizes and rules on RVs, tiny homes and accessory dwellings depend on the district and are set in the township ordinance, not by the county¹⁴. We could not confirm those district figures, so ask Community Development which district a parcel is in before you plan anything⁸.

Do you need a building permit in Upper Allen Township?

Yes, for most construction. The township has adopted the Pennsylvania Uniform Construction Code as its building code², and building permits are required for residential alterations and renovations, subject to the code's exceptions⁷. New construction, demolition, additions and electrical, plumbing or HVAC work all need permits¹³.

Accessory structures larger than 400 square feet and decks attached to a foundation need permits too⁷. Local amendments to the building code set a frost depth of 36 inches². Fees are set by the township board by resolution, so ask the office for the current schedule¹⁵.

Who issues building permits in Upper Allen Township?

The township does, through its Community Development Department at 100 Gettysburg Pike in Mechanicsburg⁸. The township designates one of its own employees as the building code official to enforce the code on its behalf³. Cumberland County does not issue building permits for the township; the county's planning department reviews subdivision and land-development plans only¹⁶.

How do septic permits work in Upper Allen Township?

Pennsylvania requires a permit from the local agency before an on-lot sewage system is installed or a building served by one is occupied⁵. Local agencies can be a municipality, a group of municipalities or a county health department¹⁷. Cumberland County's own materials say septic permits are handled locally through a Sewage Enforcement Officer, not the county planning office¹⁸.

We could not confirm which agency serves a parcel inside Upper Allen Township, or whether the township's sewer system reaches a given lot. Ask the township's Community Development office first, since public sewer, where available, changes the answer⁸. Homeowners may drill their own private water well¹².

Can you live in an RV or tiny home in Upper Allen Township?

We could not confirm this. The township's use table that would answer it for RVs, temporary camping and tiny homes was not reviewed, so no rule can be stated. Pennsylvania's published RV rules cover state park campgrounds, not private land¹⁹. A manufactured home carrying the federal label is generally installed under the manufacturer's approved design, with local utility connections and grading still subject to the Uniform Construction Code²⁰. Because the township zones, ask the Community Development Department whether the use is allowed in the specific district before buying⁸.
