New Castle, Pennsylvania Building Permit Guide

In the City of New Castle, building permits are issued under the Uniform Construction Code by the city, which opted in to enforce it in 2004. The Planning / Zoning Office at City Hall, 230 North Jefferson Street (724-656-3525), posts the residential and commercial UCC permit applications, the occupancy permit, sign permit and Zoning Hearing Board forms, while Code Enforcement (724-656-3539) handles demolition, dumpster and street excavation permits. New construction and alterations may qualify for a city property-tax exemption if the application is filed when the building permit is secured.

What requires a building permit in New Castle?

New Castle’s residential permit form covers new construction, additions, alterations and repairs to houses, and the commercial form covers new commercial buildings, alterations, repairs, demolition and signs, with separate plumbing, electrical and mechanical permits attached. The city’s sample site drawing includes small projects too: a fence, a hot tub on a concrete pad and a shed being taken down.

The UCC itself exempts some small work; New Castle’s building code text is on eCode360 rather than the city site, so ask the Planning / Zoning Office before deciding a small job needs no permit.

What New Castle decides and what the state holds

New Castle opted in to enforce the Uniform Construction Code on July 4, 2004, and L&I’s list shows the city kept building code amendments that predate the UCC; the building code official is reached through City Hall. City Council sets the Planning and Zoning Code (Part 13 of the codified ordinances), the zoning map, the street excavation rules (Article 901), the demolition rules (Article 1731) and the local tax exemption for improvements. In 2026 Council has already amended the zoning map twice (Ordinances 8495 and 8496, February 10, 2026), and in November 2025 it adopted Article 916 on signs attached to poles.

New Castle building department: who handles permitting

The Planning / Zoning Office administers the Zoning Ordinance and holds the UCC permit forms; under the city’s description of the Zoning Officer’s duties, permits issue only where the work complies with the zoning ordinance, other city ordinances and state law, and every application and plan is recorded and kept as a public document. The city’s Zoning Board of Appeals form lets an applicant appeal the Building Inspector’s refusal of a building permit. Code Enforcement, with its own director and officers, handles demolition, dumpster and street permits, property maintenance and the health complaints that the city’s Health Department page sends to it.

New Castle permit types

The city posts six land-use and building forms on the Planning / Zoning page: the residential construction permit, the commercial construction permit packet, the occupancy permit, the sign permit, the conditional use application and the Zoning Board of Appeals notice of appeal. Code Enforcement posts the demolition, dumpster and street excavation forms and the tax-abatement applications.

Residential permits

The residential application asks for the owner, the property location, a description of the work, the total square footage and estimated cost, and the builder. Page two is the “Detailed Site and Construction Improvement Drawing”: the city’s example shows the street and sidewalk, property line dimensions, the house footprint with distances to every lot line, porch, driveway, garage, a 6-foot fence with its length, a hot tub on a 6-inch concrete slab and a shed marked for demolition. By signing, the applicant agrees to follow the city’s codes and the sewer and water authority’s requirements and acknowledges the smoke detector rules for alterations, repairs and additions.

Commercial permits

The commercial packet combines the building permit with plumbing, electrical and mechanical permit pages and a commercial plan review checklist. The plumbing page counts every fixture and asks whether the site uses public sewer or a private septic system and public water or a private well; the electrical page lists the service, panels, pools and fire alarm system; the mechanical page covers the heating system and fuel. The checklist asks for complete drawings including electrical, mechanical, plumbing and energy details, a site plan showing grades, demolition, parking and accessible routes, sheets at least 15 by 24 inches drawn at no smaller than 1/8 inch to the foot, floor plans, elevations, cross sections, door, window and room finish schedules, and sprinkler and fire alarm plans, with the owner’s name, address and phone on every document.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning approval. The Zoning Officer forwards special exceptions and variances to the Zoning Hearing Board and conditional uses to City Council, and posts notice on the property at least one week before a hearing.
• Subdivision. No building permit or zoning certificate is issued until any required subdivision has final approval under the Subdivision and Land Development Ordinance; Council approves subdivision and lot-consolidation plans by ordinance.
• State highway access. The applicant must obtain any PennDOT Highway Occupancy Permit required under Section 402 of the State Highway Law.
• Sewer and water. The permit forms make the applicant responsible for the municipal sewer and water authority’s requirements; the city site links the New Castle Sanitation Authority’s online bill payment.
• Floodplain. New Castle participates in the National Flood Insurance Program; in an October 2026 federal floodplain notice for a new park at East North and North Mill streets, the city said structures there would be raised at least 2 feet above the base flood elevation.
• Street openings. Work in a street or sidewalk needs a Street Excavation and Paving Cut Permit under Article 901, signed off by the City Engineer or Public Works Director, with the city’s pavement restoration details.

New Castle permit costs and fees

New Castle’s permit forms list the parts of each fee but print no dollar amounts; the department fills them in when it reviews the application, so ask the Planning / Zoning Office (724-656-3525) for the fee on your project before you file. The forms show how a permit is priced:

The state UCC fee is $4.50 per permit, so expect that figure rather than the $4.00 printed on the commercial packet. For improvements, Ordinance 6733 (passed October 22, 1981) offers a property-tax exemption on qualifying alterations or new construction, and the exemption application, available from the zoning department, must be filed with the city when the building permit is secured. The commercial form cites Ordinance 6735 for the same exemption, and Code Enforcement posts the LERTA and school district tax-abatement applications.

Trade permits and who may pull them

For commercial work, New Castle issues separate plumbing, electrical and mechanical permits as part of the commercial packet, each with its own plan review fee. Each trade page names the contractor (or marks the builder as the contractor) and the estimated cost of that trade’s work, and the electrical page also asks for the utility company and its work order number. The plan review checklist sets what each trade must submit: for plumbing, the occupant load, fixture counts, riser diagrams and water supply sizing; for electrical, labeled equipment, lighting and power plans, panel schedules and service details; for mechanical, equipment capacity, duct layouts, outside-air schedules and combustion air.

The city’s pages do not set a local electrician, plumber or contractor license; the forms ask for the builder’s and contractor’s names and addresses. Home improvement contractors register with the state Attorney General under HICPA.

How to apply for a New Castle building permit

Review, corrections and what causes delay

State rules give a complete residential application 15 business days and a commercial one 30 for a decision unless extended in writing. In New Castle, zoning steps can add time: a special exception or variance needs a Zoning Hearing Board order and posted notice at least a week before the hearing, a conditional use needs City Council, and a lot that must be subdivided or consolidated needs Council’s plan approval first.

Inspections in New Castle

UCC inspections are carried out by the city’s building code staff; arrange them through City Hall (724-656-3500). A business moving into a building files the city’s Occupancy Permit Application, describing the business, before it opens.

Demolition inspections and rules

Demolition has its own inspection points in the technical specification attached to the city’s demolition permit packet. All utilities must be disconnected first, and sewer laterals are plugged at the property line with concrete, cast iron or tile plugs. The contractor must notify the city before backfilling so an inspector can check the basement, and backfill goes in layers no deeper than 18 inches, using masonry rubble no larger than 1 cubic foot or approved gravel or sandy soil, with no wood, metal or organic material. Burning on site is prohibited, water for dust control comes from a hydrant arranged and paid for with the city, and closing a street needs 24 hours’ notice to the police traffic division. The applicant must carry bodily injury and property damage insurance and produce receipts showing the debris went to a DEP-approved site.
