Barndominium Builders in Allentown, Pennsylvania

Allentown barndominium inquiries split cleanly between two kinds of site. Inside the city, a new barndominium means an infill or replacement lot on public water and sewer. Just outside it, the townships of Lehigh County still offer larger parcels where a shop bay, a long driveway and room for equipment are realistic. We work on both. Pennsylvania Barndominium Builders puts together steel and pole barn homes for Lehigh Valley owners: a kit package when you have your own crew, a set of plans fitted to your lot, or a turnkey project where we schedule the trades and inspections for you. For a lot inside Allentown, the City's Bureau of Building Standards and Safety administers the construction code, and Lehigh County Authority runs the water and sewer system under a long-term lease. For land in a neighboring township, that township issues the permit instead, so the address matters from day one. Larger subdivisions also pass through a regional planning review, and bigger site disturbances through the county conservation district. Share your parcel through the survey, and we will confirm which municipality, zoning district and utility provider apply before any design work starts.

City-issued permitWho issues the permit

City of Allentown Bureau of Building Standards and Safety

The City has adopted the Uniform Construction Code as its building code and elected to administer and enforce it itself, designating the Bureau of Building Standards and Safety, together with the Fire Department, to do so. A lot in one of the surrounding townships is permitted by that township, not by the City.

The City enforces the code itself
Chapter 225 of the City code, adopted in 2004, makes the Uniform Construction Code the Building Code of the City of Allentown and states that the City elects to administer and enforce it. The Bureau of Building Standards and Safety and the Fire Department are designated to administer the chapter.

Who runs the water and sewer system
Lehigh County Authority operates Allentown's water and sewer utility systems under a concession lease. A settlement between the Authority and the City ended years of disputes and confirmed the lease through 2063.

Sewer service in the city
Lehigh County Authority provides direct sewer service to more than 33,000 residential and commercial properties in Allentown. The city system is the hub of a regional network: wastewater from western Lehigh County is treated at the Kline's Island Wastewater Treatment Plant, which serves more than 150,000 people.

Regional review of new lots
The Lehigh Valley Planning Commission reviews every subdivision and land development plan for all 62 municipalities in Lehigh and Northampton counties, checking consistency with the regional plan and sending the municipality a review letter that often includes advisory guidance.

Erosion plans before a building permit
The Lehigh County Conservation District explains that where earth disturbance needs a state E&S or NPDES approval, a municipality may not issue a building permit until that plan or permit is approved. A written E&S plan is required from 5,000 square feet of disturbance, and an NPDES permit from one acre.

Building on land around Allentown

Land in Allentown itself is mostly developed, so a barndominium inside the city usually replaces an older building on a lot already served by Lehigh County Authority's water and sewer lines; the lot's zoning district then sets height and setbacks. Buyers after more room tend to look at the surrounding Lehigh County townships, where parcels are larger and some sit beyond the sewer lines, so the soil has to pass testing by the local Sewage Enforcement Officer before a septic system can be permitted. If grading and clearing reach an acre, the NPDES approval has to come before the building permit. Our pole barn homes page covers a frame that works well on a larger rural parcel.

Building in Allentown: questions

Start the survey
How much does it cost to build a barndominium near Allentown?
Start with the site. An Allentown infill lot may need demolition, new utility connections and careful staging on a tight street, while a township parcel may need a driveway, a well and an on-lot septic system. Size and finish level set the rest. The barndominium cost guide has sourced per-square-foot ranges, and the survey lets us price your specific parcel.
Do I need a building permit for a barndominium in Allentown?
Yes. Inside city limits, the City administers the construction code itself through its Bureau of Building Standards and Safety, which handles the permit and inspections. If the land is in Salisbury, Whitehall or another neighboring township, that township issues the permit. Large site disturbances also need erosion-control approval before any building permit is issued.
Who provides water and sewer for a new Allentown home?
Lehigh County Authority, which operates the City's water and sewer systems under a lease that runs through 2063. It serves more than 33,000 properties with sewer in Allentown, so connection questions for a city lot go to the Authority rather than to City Hall.
Can I buy barndominium kits for a lot near Allentown?
Yes. Our barndominium kits are designed for owners who will erect and finish the building with their own crew, and we can draw custom plans that fit the kit to your parcel and to what the municipality's permit office asks for.
