Does Lower Paxton Township, PA have zoning?

Yes. Lower Paxton Township has its own zoning ordinance, Chapter 203 of the township code¹. The township states that land use within its borders must comply with that ordinance, which names the uses allowed in each district³. Zoning here is not a county function: Dauphin County does not run one countywide zoning ordinance, and each township or borough sets its own⁵.

What the ordinance means for RVs, tiny homes, minimum lot size, setbacks and home size depends on the zoning district of the parcel, and we could not confirm those district rules. Ask the Community Development Department which district a parcel is in and what it allows before you buy³.

Land division is also regulated: the township has a subdivision and land development chapter, so splitting a lot needs township approval⁸.

Do you need a building permit in Lower Paxton Township, and who issues it?

Pennsylvania's Uniform Construction Code requires the property owner or an authorized representative to obtain a building permit before starting construction or building work⁶. Lower Paxton Township has adopted the 2018 International Residential Code and 2018 International Building Code², and its Community Development Department is responsible for building construction activities³.

The state code lists small exemptions, such as certain fences and low retaining walls, so ask before assuming a project is exempt¹⁰. A certificate of occupancy must be issued before a building can be used¹¹. We could not confirm the township's fee schedule or its permit steps; the township's online permit portal is the place to start³.

How do septic permits work in Lower Paxton Township?

Septic permits inside Lower Paxton Township come from a sewage enforcement officer employed by the township, not from the county⁴. No one may install, construct or alter an individual or community sewage system without that permit⁷. After construction, a system may not be covered until the body that issued the permit approves it¹².

Existing systems are inspected whenever they are pumped, so a township-registered pumper files a report on the township's septic form¹³. We could not confirm whether public sewer connection is mandatory on a given parcel; ask the township before you plan on-lot septic³.

Building a home in Lower Paxton Township: the steps, in order

1. Ask the Community Development Department which zoning district the parcel is in and what uses it allows³.
2. Check subdivision rules if the lot will be split⁸.
3. Apply for the building permit under the 2018 codes².
4. Get a septic permit from the township sewage enforcement officer if the parcel is not on public sewer⁷.
5. If the driveway meets a state highway, a PennDOT Highway Occupancy Permit is required⁹.
6. Schedule the required inspections and obtain the certificate of occupancy before moving in¹⁴¹¹.

What stays with Dauphin County and the state before you buy land in Lower Paxton Township?

Dauphin County itself does not issue building permits; its municipalities enforce the state code¹⁵. Floodplain development in a mapped flood area needs a permit from the municipality before work begins¹⁶. Driveway access to a state highway needs PennDOT approval⁹.

For land outside the township, see the Dauphin County page. Dauphin County's effective property tax rate is 1.4%¹⁷, and the typical home value is about $283,640¹⁸. Soil matters for septic: USDA rates only 9.4% of Dauphin County soils as not limited for a conventional drain field, so expect a site evaluation¹⁹.

Watch-outs

• Zoning-district rules for RVs, tiny homes, lot size and setbacks were not confirmed; call the Community Development Department at 717-657-5600 before relying on any use³.
• Septic permits come from the township's sewage enforcement officer, so a county or state office will not issue them for an address in Lower Paxton Township⁴.
• A building permit does not cover driveway access to a state road, which needs a separate PennDOT permit⁹.
