Before You Build in Bethlehem, PA: Permit & Rule Checklist (2026)

Bethlehem requires a zoning permit from the Bureau of Code Enforcement for any fence installation as part of general zoning compliance under Article 1318 (height, location, sight triangle, materials). Pennsylvania's Uniform Construction Code (34 Pa. Code Ch. 401-405) exempts residential fences six feet and shorter from a separate UCC building permit, but Bethlehem's local zoning permit still applies. Pool barrier fences must additionally meet the PA UCC-adopted ISPSC 2018, regardless of permit type.

Bethlehem's zoning code does not require neighbor consent for a boundary fence under Article 1318, but Pennsylvania common-law partition-fence principles and trespass / ejectment law still govern shared-line disputes. The City enforces public zoning law - height, location, materials, sight triangle - while leaving private property-line and cost-sharing fights to Lehigh County or Northampton County Magisterial District Courts or the Court of Common Pleas, depending on the value at issue.

Bethlehem Zoning Code Article 1318 does not impose a separate list of prohibited fence materials, leaving fence-material regulation to general property-maintenance and nuisance standards. The City has adopted the International Property Maintenance Code through Codified Ordinances Chapter 1727, which prohibits junk, debris, and dilapidated structures - including fences in dangerous or deteriorated condition. Historic districts (South Bethlehem Historic Conservation District) impose additional material restrictions through Bethlehem Historic Conservation Commission (BHCC) design review.

Bethlehem Zoning § 1322(yy)(4) expressly refers pool fencing to the Pennsylvania Uniform Construction Code, which adopts the 2018 International Swimming Pool and Spa Code (ISPSC) statewide under 34 Pa. Code Ch. 401-405. ISPSC § 305 sets the controlling barrier rule: at least 48 inches above grade, 4-inch sphere test on openings, 2-inch maximum gap at the bottom under most conditions, and a self-closing / self-latching outward-opening gate with latch hardware at least 54 inches above grade. The water surface of the pool must additionally be at least 6 feet from any side or rear lot line under Bethlehem Zoning § 1306.03(b)(4).

Bethlehem Zoning Code allows fences, hedges, or walls up to seven (7) feet above natural grade in front, side, and rear yards under § 1318.13 (Fences and Terraces in Front Yards), § 1318.15 (Fences and Terraces in Side Yards), and the rear-yard rule in § 1318.16 - meaning a 7-foot fence is permitted in any required yard subject only to the corner sight-triangle rule. Section 1318.06 imposes a 2.5-foot maximum height for any visual obstruction within the 25-foot corner sight triangle in residential zones (8 ft in commercial). Height is measured above natural grade.

Any swimming pool in Bethlehem - in-ground or aboveground - capable of holding water more than 24 inches deep requires both a City zoning permit under Zoning Code § 1322(yy) and § 1306.03 (location, setback) and a UCC building permit under 34 Pa. Code Ch. 403 (structural, electrical, ISPSC 2018 barrier compliance). The City's separate stand-alone pool ordinance (former Article 1711) was repealed in 2004, leaving the zoning code plus the statewide PA UCC as the controlling rules. Hot tubs and spas with secure locking covers may be exempt from the fence rule under ISPSC § 305.5 but still need a UCC electrical permit.

Pool fencing in Bethlehem is governed by Pennsylvania's adoption of the 2018 International Swimming Pool and Spa Code under the PA Uniform Construction Code (34 Pa. Code Ch. 401-405), as cross-referenced by Bethlehem Zoning § 1322(yy)(4). ISPSC § 305 sets a 48-inch barrier, 4-inch sphere test on openings, 2-3/8-inch maximum bottom gap, self-closing / self-latching outward-opening gate, and latch hardware at 54 inches. The water surface must be at least 6 feet from any side or rear lot line under Bethlehem Zoning § 1306.03(b)(4).

Bethlehem pool owners must comply with: (1) the Virginia Graeme Baker Pool and Spa Safety Act (15 U.S.C. § 8003) anti-entrapment drain-cover requirements; (2) the ISPSC 2018 alarm, suction, and circulation safety provisions adopted statewide under the PA UCC; (3) NEC Article 680 electrical bonding and GFCI rules; and (4) Bethlehem stormwater Article 925 plus the City's NPDES MS4 permit, which prohibit chlorinated pool-water discharge to the storm sewer system. Public pools are additionally licensed and inspected under 28 Pa. Code Ch. 18.

Bethlehem is a Pennsylvania city of approximately 75,781 residents that straddles Lehigh County and Northampton County in the Lehigh Valley. The City of Bethlehem Code is hosted on American Legal Publishing at https://codelibrary.amlegal.com/codes/bethlehem/, and the Bethlehem Zoning Ordinance is maintained as a separate comprehensive document that the City rewrote in a multi-year process completed around 2023. Pennsylvania has not enacted any statewide accessory dwelling unit (ADU) preemption statute comparable to California Government Code §66313 et seq. or Oregon ORS 197.312, so whether an ADU (sometimes called an accessory apartment, in-law suite, or second dwelling unit) is permitted on a Bethlehem property is determined entirely by the Bethlehem Zoning Ordinance under the Pennsylvania Municipalities Planning Code (53 P.S. §10101 et seq.). Property owners should request a written zoning determination from the Bethlehem Department of Community and Economic Development before making design or financing commitments.

Converting a Bethlehem garage into habitable space (a bedroom, in-law suite, home office, or accessory dwelling unit) requires both (1) zoning approval under the Bethlehem Zoning Ordinance for the change of use — because the converted space is no longer accessory parking and may count toward floor area or trigger an ADU classification — and (2) a building permit under the Pennsylvania Uniform Construction Code at 34 Pa Code §401.7. Conversions must comply with the 2018 International Residential Code for habitable spaces (egress windows under IRC R310, ceiling height under IRC R305, light and ventilation under IRC R303, smoke alarms under IRC R314, carbon monoxide alarms under IRC R315), and Bethlehem's local off-street parking minimums must still be met after the garage is repurposed.

Sheds and similar accessory structures in Bethlehem are regulated by two overlapping layers: (1) the Bethlehem Zoning Ordinance, which sets dimensional standards (maximum size, height, setbacks, lot coverage, and location relative to the principal dwelling) by zoning district; and (2) the Pennsylvania Uniform Construction Code at 34 Pa Code §403.1, which exempts certain non-residential utility sheds under 1,000 square feet from UCC building-permit requirements but does not exempt them from local zoning compliance. Bethlehem property owners typically still need a zoning permit from the Bethlehem Department of Community and Economic Development even when no UCC building permit is required, especially in older row-house neighborhoods of Historic Bethlehem and South Bethlehem where rear-yard space is constrained.

Bethlehem, PA (Lehigh and Northampton Counties, population approximately 76,000) effectively bans backyard recreational fires. Article 1501 of the Codified Ordinances adopts the 2018 International Fire Code, and Section 1501.05(r) amends IFC Section 307.4.2 to read 'Recreational fires are prohibited.' Portable outdoor fireplaces are allowed only 'where approved' by the Fire Marshal, and must be 25 feet from any structure and 15 feet from combustible material under amended IFC 307.4.3.

Bethlehem restricts open burning through Article 1501 (the locally adopted 2018 IFC) and statewide air-quality rules at 25 Pa. Code Section 129.14. Open burning is allowed only at least 50 feet from any structure, with a 25-foot exception only where specifically approved by the Fire Marshal. Burning of leaves, yard waste, household garbage, treated wood, plastic and tires is prohibited. Recreational wood fires are prohibited entirely under Section 1501.05(r).

Trimming any tree on a public area in Bethlehem requires a permit from the Director of Public Works under Article 910.04 of the Codified Ordinances of the City of Bethlehem (https://www.bethlehem-pa.gov/CityOfBethlehem/media/Ordinance-PDFs/ARTICLE0910.pdf), with a $25 application fee under 910.05(b) and an arborist license under 910.10. Trees wholly on private property and outside the public right-of-way are not subject to Article 910's permit requirement. Pennsylvania common-law self-help allows trimming a neighbor's overhanging branches up to the property line.

The City of Bethlehem owns its water supply through the Bethlehem Authority, drawing from Pocono Mountain reservoirs holding approximately 10 billion gallons across roughly 23,000 acres of protected watershed. Article 911 (Water Regulations) authorizes the City to request voluntary conservation and, if needed, to impose mandatory restrictions during a supply shortage. Statewide drought stages — Watch, Warning, Emergency — are declared by PA DEP under the Pennsylvania Drought Emergency Act (35 Pa.C.S. and 4 Pa. Code Chapter 119). Mandatory measures attach only at a gubernatorial Drought Emergency.

Tree removal in Bethlehem is governed by Article 910 of the Codified Ordinances of the City of Bethlehem (https://www.bethlehem-pa.gov/CityOfBethlehem/media/Ordinance-PDFs/ARTICLE0910.pdf). No person may remove any tree on a public area without a permit from the Director of Public Works under 910.04(a), with a $25 application fee under 910.05(b). Article 910.04(b) authorizes the Director to require replacement plantings as a condition of the permit. Unauthorized removal of a public tree carries a minimum $1,000 fine per tree under 910.08(m), with the abutting owner and the actor jointly and severally liable.
