Zoning, building permits and septic rules in New Castle, Pennsylvania

The City of New Castle, Pennsylvania (Lawrence County) runs its own zoning, with a Zoning Officer appointed by City Council1. Building work follows the state Uniform Construction Code, which the city adopted as its municipal building code2. Inside city limits, septic tanks are approved by the city's Sewer Enforcement Officer3. Land outside the city falls under Lawrence County and township rules.

Does New Castle, PA have zoning, and what does it mean for lots and setbacks?

Yes. The City of New Castle has its own zoning ordinance, and City Council appoints the Zoning Officer who administers and enforces it1. The city is divided into districts, and the permitted uses, conditional uses and special exceptions for each are listed in a use table4. Lawrence County itself has no countywide zoning ordinance, so the city's ordinance is the one that governs a lot inside city limits11.

Dimensions depend on the district. In the R-1 Low Density Residential District, a single-family lot needs 6,000 square feet per family and 50 feet of width, though an existing lot of record can still hold a single-family house when smaller8. Setbacks in R-1 are 20 feet in front, 30 feet in back and 5 feet on each side12. Buildings may cover no more than 35 percent of an R-1 lot13, and a principal structure may be up to 35 feet tall, an accessory structure 15 feet14. Check your parcel's district first with the city's Planning / Zoning office at 724-656-352515.

Do you need a building permit in New Castle, PA, and who issues it?

Yes. Pennsylvania's Uniform Construction Code requires the owner or an authorized agent to get a building permit before constructing, enlarging, altering, repairing or moving a residential building5, and New Castle adopted the Uniform Construction Code as its municipal building code2. Lawrence County's planning office says building permits are obtained by contacting the municipality where the building is going16, so inside New Castle the starting point is the city's Code Enforcement Department at 724-656-353917.

The city sets its permit fees by resolution from time to time, so ask for the current schedule18. A separate zoning certificate comes from the Zoning Officer: the application needs a property plan and a $10 filing fee, and the certificate expires six months after it is issued6. We could not confirm from the city code which projects trigger a building permit in full detail, so call Code Enforcement before you start.

How do septic permits work inside New Castle, PA?

Inside the city, the Sewer Enforcement Officer inspects the property, prescribes the kind of septic tank, supervises installation, and must approve the tank before it is used3. That is a city process, not a Lawrence County one. Pennsylvania law requires a permit from the local agency before a building served by an on-lot system is occupied or used19.

Before planning any septic system, check for a sewer. The city requires a new building with a water closet or wastewater discharge to connect to a public or private sanitary sewer if one runs in the street, alley or right of way abutting the property, on or before the date of occupancy7. Septic tanks must also stay uncovered until the permitting body approves them20. To find the active Sewage Enforcement Officer for a parcel, use the DEP directory21.

Can you live in an RV or tiny home in New Castle, PA?

We could not confirm a rule for RV living, temporary camping or tiny homes on private land in New Castle, so do not assume any of them is allowed. The Zoning Officer at 724-656-3525 is the person to ask for a written answer about your specific lot and district15.

One related rule we did find: a mobile home court or development is a conditional use in the R-3 High Density Residential District, which means it needs approval rather than being allowed outright22. Pennsylvania's rules about state park campgrounds do not answer whether you can live in an RV on your own lot23.

What are the steps to build a home in New Castle, PA?

  1. Confirm the zoning district and its setbacks, lot size and height limits with the Zoning Officer415.
  2. If the work divides land or is a land development, plans go to the Planning Commission, and City Council keeps final approval24.
  3. Apply for the zoning certificate with a property plan and the $10 filing fee6.
  4. Get the Uniform Construction Code building permit through the city's Code Enforcement Department217.
  5. If the driveway crosses a sidewalk, apply to the City Engineer; the permit fee is $100 per driveway9. A driveway onto a state highway needs a PennDOT highway occupancy permit instead25.
  6. Connect to sewer where one abuts the lot, or have the Sewer Enforcement Officer approve a tank73.
  7. Pass the required inspections before the building is occupied; a residential building may not be used or occupied without a certificate of occupancy26.

What stays with Lawrence County, and what should you check before you buy?

Land outside New Castle's limits is a different case, and the Lawrence County page covers it. Lawrence County has no countywide zoning ordinance, and building permits are obtained from the municipality where the building is going1116. Water wells are regulated statewide: drilling companies must hold a license and permits27. Lawrence County's effective property tax rate is 1.5 percent, with a median bill of $1,983 a year2829.

Floodplain: Pennsylvania requires the municipality to issue a floodplain development permit before development in a Special Flood Hazard Area30. We did not confirm the city's own floodplain provisions, so ask Code Enforcement whether a parcel is in a mapped flood zone.

Watch-outs

  • We could not confirm whether the city has an owner-builder exemption from its building permit requirement, or a rule on accessory dwelling units, short-term rentals or agricultural buildings; ask Code Enforcement at 724-656-353917.
  • The R-1 numbers above apply only to the R-1 Low Density Residential District; other districts have different lot sizes, setbacks and heights8.
  • Inside city limits, septic tanks are approved by the city's Sewer Enforcement Officer, and a sewer connection is mandatory where a sewer abuts the property37.
  • Pennsylvania has a state exclusion for agricultural buildings from the Uniform Construction Code, but it does not allow an unpermitted dwelling31.
