Building permits, zoning and septic rules in Lehigh County, Pennsylvania
49Index Score / 100 #57 of 67 in Pennsylvania
Building work in Lehigh County, Pennsylvania needs a building permit under the statewide Uniform Construction Code, but the permit comes from your township, borough or city (or its third-party agency), not from the county12. Lehigh County has no zoning authority, so zoning is set by the municipality, including Allentown and Heidelberg Township345. On-lot septic permits come from the local Sewage Enforcement Officer6.

Do you need a building permit in Lehigh County, Pennsylvania?
Yes. An owner or authorized agent in Lehigh County must obtain a permit before constructing, enlarging, altering, repairing, moving or demolishing a residential building, changing its occupancy, or doing regulated electrical, gas, mechanical or plumbing work15. Ordinary repairs and several listed projects are exceptions, and emergency work may begin if the application follows within 3 business days15.
The statewide Uniform Construction Code applies in Lehigh County, with enforcement by the municipality, a certified third-party agency or, in opt-out situations, the Department of Labor & Industry216. The 2018 I-Code regulations took effect February 14, 2022, and the 2025 triennial update has an effective date of January 1, 2026, so ask the building code official which edition applies to your project2.
Inspections cover residential building construction and changes, electrical, gas, mechanical and plumbing work, and pools and hot tubs17. The permit holder must tell the code official when work is ready for stage and final inspections18. A residential building cannot be occupied without a certificate of occupancy issued after a compliant final inspection1920.
Qualifying agricultural buildings with no habitable space are excluded from the Construction Code Act, though other local and state rules may still apply21.
Who issues building permits in Lehigh County, and what do they cost?
Start with the township, borough or city governing the Lehigh County parcel to identify the UCC building-permit issuer; municipal, certified third-party and Department jurisdiction depend on local enforcement arrangements816. Of the places we checked, Heidelberg Township handles its own building permits, while on-lot sewage questions go to the township's Sewage Enforcement Officer2223. Use the county municipality directory to identify the local government24. Request the administering municipality or third-party agency's public fee schedule for plan review and inspections25. Where the Department of Labor & Industry issues the UCC permit, its published standard fee for new buildings and additions is $414.49 plus $0.84 per square foot or fraction; local fees may differ26. Department fees cover plan review and inspections, with additional charges for expedited review or inspections outside normal hours27. The state UCC office answers code-administration questions at 717-787-3806 or uccbois@pa.gov28.
Does Lehigh County have zoning?
Lehigh County has no authority over zoning laws; zoning requirements are administered by the township, borough or city where the parcel lies38. The city of Allentown has its own zoning chapter in its code of ordinances4. Heidelberg Township administers its own zoning; on-lot sewage matters remain with its Sewage Enforcement Officer523. In unincorporated Lehigh County, we could not confirm county zoning minimum lot sizes, setbacks or minimum dwelling sizes; municipal zoning, subdivision and land-development rules may impose those requirements293031. Ask the parcel's municipality about permitted uses, setbacks, minimum dwelling size, lot coverage, building height, RV occupancy and tiny-home siting8. Septic stays separate from municipal zoning: on-lot sewage permits come from the local sewage agency, which may serve several municipalities6. Subdivision rules require a separate check: a municipal subdivision and land-development ordinance controls where one exists, while a county ordinance may apply where the municipality has none32. Use the county municipality directory to identify the correct government before relying on a listing description or designing a project24.
How do septic permits work in Lehigh County?
The applicable local agency handles on-lot septic permitting and enforcement in Lehigh County through Sewage Enforcement Officers336. Local agencies issue permits for retaining tanks and individual or community on-lot systems, subject to exceptions such as large-volume systems34. A limited exemption can apply to an individual system serving an owner or immediate-family residence on a contiguous tract of at least 10 acres, but only under specific ownership-date, siting and notification conditions35. After installation, the system cannot be covered until the permit issuer approves it, or until 72 hours pass after notice that the work is complete, whichever comes first36. Only 17.8% of Lehigh County's mapped soil is rated free of severe limits for a conventional septic drain field, so arrange a site and soil evaluation before committing to a parcel12. Use the state's directory to find the active Sewage Enforcement Officer serving the municipality37.
Can you live in an RV or tiny home on your land in Lehigh County?
In unincorporated Lehigh County, we could not confirm a county zoning rule for RV or tiny-home occupancy, but that does not mean municipalities allow either: township, borough and city zoning, building-code, sewage and floodplain rules may still restrict occupancy3839. We could not confirm one Lehigh County rule that authorizes living in an RV or tiny home on private land, so ask the township, borough or city zoning officer about the exact parcel and proposed use8. A tiny home used as a dwelling must follow the UCC permit, inspection and occupancy process when the work is regulated, while local zoning may control siting, minimum size and setbacks4018418. Manufactured housing has specialized UCC treatment, but the state rule does not resolve local siting or utility approval42. Before buying, get the municipality's answer on occupancy and placement and ask the applicable local or joint local agency about wastewater service843.
How do you build a home in Lehigh County, step by step?
Identify the municipality governing the parcel through the county's boroughs and townships directory24.
Ask that municipality about zoning, setbacks, proposed use and the appropriate UCC building-permit issuer816.
Arrange the site evaluation and required on-lot sewage permit through the applicable local sewage agency634.
Obtain the issuer's fee schedule, submit required plans and specifications, and receive the building permit before regulated work begins25441.
Obtain the municipality's floodplain development permit before work in a Special Flood Hazard Area; a driveway connecting to a state highway also needs a PennDOT Highway Occupancy Permit4546.
Notify the code official when work is ready for inspections and obtain the certificate of occupancy before using the home1847.
What should you check before buying land in Lehigh County?
Soils: 17.8% of Lehigh County's mapped soil is rated free of severe limits for a conventional septic drain field, so have the local Sewage Enforcement Officer evaluate the specific lot before purchase126. Flood: a Pennsylvania municipality must issue its own floodplain development permit before work can begin in a designated Special Flood Hazard Area, so check your parcel against your township or borough's floodplain ordinance before you buy45. Access: a driveway or road connecting to a state highway needs a PennDOT Highway Occupancy Permit from District 5, usually issued within about 30 days when the application is complete4846. Water: a homeowner or farmer can drill their own well without the commercial driller's license Pennsylvania requires for well-drilling companies, though the state sets construction standards only for public water-supply wells, not private ones49. Taxes: Lehigh County's typical effective property tax rate is 1.7% of value, with a median annual property tax bill of about $4,5911314.
Watch-outs
Lehigh County has no zoning authority, but municipal zoning may still control the parcel; ask the township, borough or city rather than treating the land as unrestricted38.
The Department of Labor & Industry's published UCC fees apply where the Department issues the building permit; obtain the local municipality or third-party agency's schedule before budgeting a Lehigh County home2625.
On-lot sewage administration may be municipal or shared by multiple municipalities; use the state's Active SEOs by County directory to find the Sewage Enforcement Officer serving the parcel937.

Manufactured homesLimited
Manufactured housing assembled and shipped by the manufacturer and bearing the required federal-construction-and-safety label, including changes in occupancy, resale, relocation, additions, repairs, utility connections, and grading addressed by Pennsylvania's Uniform Construction Code.
For new labeled manufactured housing installed in conformity with the manufacturer's approved design, the UCC does not apply except as provided in the regulation.
Construction activities or processes, including utility connections and grading, that are not addressed by the manufacturer's approved design must comply with the UCC.
The UCC applies to alterations or repairs outside the federal manufactured-home standards and manufacturer installation instructions after assembly and shipment.
The UCC applies to additions after delivery to the site.
The UCC applies to construction, alteration, repair, or change of occupancy if the manufactured housing is resold to a subsequent purchaser.
The UCC applies to construction, alteration, repair, or change of occupancy if the original purchaser relocates the manufactured housing.
Pennsylvania building-permit guidance states that manufactured housing projects require inspections for site preparation, foundation construction, repairs, and changes in occupancy.
This state construction-code rule does not resolve local zoning, land-use siting, or utility/septic approval requirements.
“Construction, alteration, repair or change of occupancy if the original purchaser relocates the manufactured housing.”
Septic inspectionLimited
Individual and community sewage-disposal systems before concealment or covering after construction.
The system may not be covered until approval to cover is given by the original permit issuer or authorized representative.
If 72 hours have elapsed after notification of construction completion, excluding Sundays and holidays, the applicant may cover the system unless permission has been refused.
post-completion waiting period: 72 hours (Sundays and holidays excluded.)
“shall be covered from view until approval to cover the same has been given by the body which issued the original permit”
Off-grid sanitationLimited
Composting, incinerating, recycling, and similar water-conservation toilets used for residential or establishment sanitation statewide.
For a new residence or establishment, an onlot sewage system or other approved disposal method must treat washwater or excess liquid, and both facilities must be under one permit, except for the retaining-tank exception.
For an existing residence or facility with no alteration of the onlot system, no permit is required for installation.
A composting or incinerating toilet on a qualifying retaining-tank lot is treated as and permitted as a privy.
The device must meet manufacturer specifications and be operated and maintained to prevent pollution or health hazards.
Liquid discharges are prohibited unless sent to a compliant onlot sewage system or another method approved under the chapter or by DEP.
Recycling, incinerating, and composting toilets must bear the NSF Standard No. 41 seal.
“an onlot sewage system or other approved method of sewage disposal shall be provided for treatment of washwater or excess liquid from the unit”
Well permitLimited
Water-well drilling statewide, distinguishing commercial water-well drillers from farmers and homeowners drilling their own wells on owned or leased land.

The governing body of each municipality may regulate subdivisions and land development by ordinance.
Subdivision and land-development plats must be submitted for approval to the governing body or a designated planning agency.
Where a municipality has enacted an ordinance under Article V, subdivision or land development may not proceed except in accordance with that ordinance.
A county subdivision and land-development ordinance may apply where the municipality has no subdivision and land-development ordinance in effect; a municipality may also adopt the county ordinance by reference.
The cited statute does not establish one statewide numeric subdivision standard; local ordinances and applicable county review determine the requirements.
“Section 501. Grant of Power.--The governing body of each municipality may regulate subdivisions and land development within the municipality by enacting a subdivision and land development ordinance. The ordinance shall require that all subdivision and land development plats of land situated within the municipality shall be submitted for approval to the governing body or, in lieu thereof, to a planning agency designated in the ordinance for this purpose, in which case any planning agency action shall be considered as action of the governing body.”
Driveway accessRequired
Construction or alteration of a driveway connected to Pennsylvania state highway land, including a driveway connecting to a PennDOT drainage facility.
The requirement applies to building or changing a driveway on state highway land.
A permit is also required if the driveway connects to a PennDOT drainage facility.

county zoning authorityLimited
County zoning authority over land in Pennsylvania municipalities that lack an effective municipal zoning ordinance.
County zoning power is limited to land in municipalities wholly or partly within the county that have no zoning ordinance in effect when the county zoning ordinance is introduced and until the municipal zoning ordinance becomes effective.
A zoning ordinance enacted by a municipality other than the county repeals the county zoning ordinance pro tanto within that municipality.
The statute defines a county under the Pennsylvania Municipalities Planning Code as a county of the second through eighth class.
“The powers of the governing bodies of counties to enact, amend and repeal zoning ordinances shall be limited to land in those municipalities, wholly or partly within the county, which have no zoning ordinance in effect at the time a zoning ordinance is introduced before the governing body of the county and until the municipality's zoning ordinance is in effect. The enactment of a zoning ordinance by any municipality, other than the county, whose land is subject to county zoning shall act as a repeal protanto of the county zoning ordinance within the municipality adopting such ordinance.”

county building authorityLimited
Pennsylvania county authority over building-code administration and enforcement for residential construction in unincorporated areas.
The general Pennsylvania Construction Code Act assigns administration and enforcement to municipalities, not counties.
A county of the second class may retain authority only if it has adopted a plumbing code and accompanying rules and regulations under the Local Health Administration Law.
The retained authority is limited to promulgating and enforcing that plumbing code and making changes that meet the minimum requirements of the Uniform Construction Code.
The official Department of Labor and Industry page states that residential UCC requirements in opt-out municipalities are enforced by certified third-party agencies hired by property owners or contractors.
“A county of the second class that has adopted a plumbing code and accompanying rules and regulations pursuant to the act of August 24, 1951 (P.L.1304, No.315), known as the Local Health Administration Law, shall retain the authority to promulgate and enforce such plumbing code and to make such changes as it deems necessary, provided that such changes meet the minimum requirements as defined in the Uniform Construction Code.”

Water rights & wells in Lehigh County
Whether a new home can legally get its own water here — the sub-state groundwater regime, from Pennsylvania’s water agency.
Actively managed
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Household wellExempt — no permit or water right
Pennsylvania does not permit private water wells (reasonable-use doctrine). Large withdrawals may need DRBC approval (>10,000 gpd inside the SE PA Ground Water Protected Area) or SRBC approval (>=100,000 gpd), but a household well is far below every threshold.
Limit: no state permit (unregulated private wells)
Southeastern Pennsylvania Ground Water Protected Area (DRBC)localized of county
DRBC protected area where new/expanded withdrawals averaging >10,000 gpd need a DRBC Protected Area Permit (vs 100,000 gpd elsewhere) because development lowered water tables and depleted streams. Household wells (~200-400 gpd) are below the threshold and unaffected; only Montgomery is wholly included.
Riparian state (water rights tied to land). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Pennsylvania state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
