Buying Land in the Lehigh Valley: Complete Guide to Zoning, Utilities, and Due Diligence

Buying land in Lehigh Valley, Pennsylvania rewards buyers who prepare carefully. Land transactions follow different rules than buying an existing home, and every municipality across the Valley can carry its own zoning classifications, utility requirements, and tax programs. Understanding those variables before you make an offer is what separates a smooth closing from a costly surprise.

The Lehigh Valley's appeal as a land market is genuine. Three municipalities in Lehigh and Northampton counties, Bethlehem, Upper Macungie Township, and Easton, ranked among Pennsylvania's top ten fastest-growing communities between 2020 and 2025, based on U.S. Census data reported by WFMZ 69 News in July 2026. The region has added roughly 21,000 residents since 2020, and its economy now measures approximately $57.3 billion. That kind of sustained growth gives land buyers a real foundation to build on, both literally and financially.

Why Lehigh Valley Stands Apart from Other PA Land Markets

Lehigh Valley stands apart from other Pennsylvania land markets for three concrete reasons: land prices run well below the Philadelphia suburbs, Route 78 and Route 22 connect buyers to major employment corridors, and the region has added more than 21,000 residents since 2020, making it one of the fastest-growing areas in the state.

From a buildable lot in the 18040 zip code (Forks Township, Northampton County) to a larger parcel tucked along the rolling hills of Upper Saucon Township in Center Valley, the range of land types is broad. Buyers relocating from New Jersey and New York are drawn here by these fundamentals, and for buyers in the 55-plus phase of life, land ownership in the Valley often means building a custom home near the things that matter most.

That includes walkable trails like the Saucon Rail Trail, easy access to major health systems including Lehigh Valley Hospital and St. Luke's, cultural anchors like the historic SteelStacks campus in Bethlehem, and the ability to design a home from the ground up in a community that fits your pace.

The Valley also benefits from a strong institutional infrastructure for land buyers. Both Lehigh County and Northampton County maintain active Recorder of Deeds offices with searchable public records, and both counties participate in Pennsylvania's Clean and Green program, which can significantly reduce the tax burden on qualifying agricultural or forested parcels.

Understanding Zoning Before You Make an Offer

Zoning is the single most important variable to research before committing to any land purchase in the Lehigh Valley, and it is where buyers are most often caught off guard.

In Pennsylvania, most municipalities write and administer their own zoning ordinances and maps. What is permitted in one township may be entirely prohibited in the one next door.

Common zoning classifications you will encounter across the Valley include:

• Residential (R-1, R-2, etc.): Single-family homes, with density and lot-size rules that vary by municipality.
• Agricultural (AG): Farming and open-space use; residential construction may be limited or require a minimum lot size.
• Mixed-use or Planned Residential: Common in newer suburban communities; may allow a mix of housing types.
• Commercial or Industrial: Permitted uses range from retail to warehousing, depending on the specific district.

A practical note for Allentown buyers: the city adopted a fully revised Zoning Ordinance and new zoning map on October 15, 2025, effective January 1, 2026, through the ZONE Allentown process. If you are considering land within Allentown city limits, you are working under a genuinely new regulatory framework.

Contact the city's Planning and Zoning office directly, or reach out to an experienced local agent who can walk you through how those updated regulations apply to your specific parcel.

Outside city limits, each township sets its own rules. Before placing an offer, confirm the current zoning classification with the local municipality. Ask whether your intended use, whether that is building a custom home, running a small farm, or holding land as an investment, is permitted by right or requires a variance or conditional use hearing.

Utilities, Infrastructure, and True Cost

Utility access is one of the biggest factors that can swing your total land investment in either direction, and it rarely shows up in the listing price.

Public water and sewer. Parcels with access to public water and public sewer are generally more straightforward and more expensive. In denser communities near Allentown, Bethlehem, and Easton, public utilities are often available. Connection fees and tap-in fees can add meaningfully to your budget, so confirm with the local municipality whether capacity is available and what those costs entail.

Private well and septic. Many parcels in the outer townships of Northampton and Lehigh counties, including areas of Forks Township, Upper Saucon, and the communities approaching Center Valley, are not served by public sewer. In those cases, you will need a private well and an on-lot septic system.

Before purchasing land that requires a septic system, a percolation (perc) test is essential. A perc test measures how quickly water drains through the soil to determine whether the land can support a septic system. If the land fails a perc test, it may not be buildable as a residential lot without engineered alternatives, which add cost.

Road access and frontage. Without legal road frontage, a parcel may be landlocked, creating significant complications for financing, permitting, and eventual resale. Confirm that the parcel has deeded access to a public road before proceeding.

Electric and gas service. These are typically easier to connect than water and sewer, but in more remote parcels, the cost of extending lines can be significant. Get a written estimate from the utility provider early in the process.

The Clean and Green Program: A Tax Tool Worth Knowing

Pennsylvania's Clean and Green program (Act 319) gives qualifying agricultural, forestland, and open-space parcels a meaningful tax advantage by basing assessments on use value rather than market value, according to the Pennsylvania Department of Agriculture. More than 12 million acres are enrolled statewide, according to the Pennsylvania Department of Agriculture.

To qualify, a parcel generally must be at least ten acres in agricultural use, agricultural reserve, or forest reserve, or capable of generating at least $2,000 annually in farm income if smaller.

The key thing buyers should know is what happens when land use changes. If you purchase a parcel that is currently enrolled in Clean and Green and then change its use, rollback taxes apply. Rollback taxes represent the difference between what was paid under the program and what would have been owed at full market assessment, going back seven years, with 6% simple interest per year. That is not a small number on a large parcel.

Both Lehigh County and Northampton County have invested significantly in farmland preservation alongside the Clean and Green program. As of June 2025, Lehigh County had permanently preserved nearly 28,800 acres across 422 farms, ranking first in Pennsylvania for preserved farmland as a percentage of its total land area, according to Lehigh County. Northampton County has preserved more than 19,000 acres across more than 250 farms through its conservation easement program, according to Northampton County.

This matters for buyers: preserved farmland cannot be developed. Always verify the preservation status of any agricultural parcel before you proceed.

Five Stages Every Land Buyer Should Expect

A Lehigh Valley land purchase moves through five key stages: title search, survey, environmental and soil due diligence, transfer tax settlement, and financing. Each stage includes steps that typically do not apply to a standard home purchase, and working through them in order keeps the process from stalling.

Title search. A thorough title search through Lehigh County or Northampton County public records is non-negotiable. It uncovers recorded liens, unpaid taxes, municipal claims, easements, and any competing ownership claims. Without it, a buyer may unknowingly inherit the previous owner's legal or financial encumbrances.

Survey. Unlike most home purchases, a boundary survey is standard practice for land. A survey confirms exact parcel boundaries, identifies encroachments, and is often required by lenders. Do not rely solely on a tax map or an old deed description for boundary information.

Environmental and soil due diligence. Depending on the parcel's history and intended use, a Phase I environmental assessment may be appropriate.

For buildable lots, soil testing and a perc test (if the parcel is off public sewer) should happen during your due diligence period, before you remove contingencies.

Realty transfer tax. Pennsylvania imposes a realty transfer tax at 1% to the commonwealth, plus an additional 1% to the local government, for a standard combined rate of 2% of the purchase price, according to the Pennsylvania Department of Revenue. Both buyer and seller are jointly and severally liable, though responsibility is typically negotiated between the parties in the contract.

Financing. Land loans are a distinct category from standard residential mortgages. Traditional lenders may require larger down payments, shorter loan terms, and higher interest rates for raw or unimproved land.

Construction loans, available for parcels where you plan to build, typically bundle lot and construction costs together. The Affordability Calculator on this site can help you work through the numbers before you approach a lender. Construction loan programs are available through multiple local lenders for land buyers planning to build, and our team can help connect you with the right fit for your project.

Matching Lehigh Valley Land Types to Your Goal

The Lehigh Valley offers four broad categories of land, and matching the parcel type to your goal is the first decision that shapes everything else: your due diligence checklist, your financing approach, and your timeline.

Land Type	Representative Areas	Key Characteristics	Best For
Residential lots in planned communities	Forks Township (18040), River View Golf area	Finished lots, HOA amenities, infrastructure in place	55+ buyers wanting a new custom home in a community setting
Suburban and township parcels	Upper Saucon Township, Center Valley	Larger tracts, scenic rolling hills, proximity to Saucon Rail Trail and Promenade Saucon Valley	Buyers who want space without isolation
Urban infill lots	Bethlehem, Easton	Smaller parcels in established neighborhoods, typically on public utilities, residential zoning	Buyers seeking walkable proximity to services and amenities
Agricultural and larger acreage	Outer townships, Northampton and Lehigh counties	Open acreage, often enrolled in Clean and Green or preservation programs	Private estate, small farm, or long-term investment

For buyers drawn to Bethlehem, the Bethlehem neighborhood guide provides a closer look at the community's character and housing landscape. If Easton is on your radar, the Easton neighborhood guide covers the riverfront corridor and surrounding residential areas in detail.

What to Ask Before You Sign

Eight questions will determine your true cost, your timeline, and whether a parcel can serve the purpose you have in mind. Get clear answers to all of them before removing any contingencies.

1. What is the current zoning classification, and does it permit my intended use by right?
2. Is public water and sewer available, and what are the connection costs?
3. Has the land been perc tested, and is a copy of the report available?
4. Is the parcel enrolled in Clean and Green, and are there rollback tax obligations?
5. Is the parcel subject to any conservation easement or farmland preservation agreement?
6. Does the parcel have legal road frontage and deeded access?
7. Are there any recorded easements, rights of way, or deed restrictions affecting the land?
8. What is the status of any existing survey, and how current is it?

Getting these answers before you submit an offer, not after, puts you in a far stronger negotiating position and avoids the kind of late-stage surprises that can unwind an otherwise solid deal.

Frequently Asked Questions About Buying Land in Lehigh Valley, PA

What is the difference between buying land and buying a home in Pennsylvania?

Land purchases involve several due diligence layers that simply do not come up in most existing-home transactions. Perc tests, boundary surveys, zoning verification, utility availability checks, and Clean and Green enrollment status all need to be confirmed before you finalize a land contract. Financing works differently too: land loans typically carry distinct terms compared with standard residential mortgages, and a construction loan is usually the right tool if you plan to build.

Do I need a perc test before buying land in the Lehigh Valley?

For any parcel not connected to a public sewer system, a percolation test is a critical part of due diligence. The test measures how well the soil drains to determine whether an on-lot septic system will work. A parcel that does not pass a perc test may not support residential construction without engineered alternatives, which can add significant cost. In Forks Township, Upper Saucon, and many outer townships in Northampton and Lehigh counties, public sewer is not always available, so verifying this early protects your investment.

What is Pennsylvania's Clean and Green program, and how does it affect a land purchase?

Clean and Green (Act 319) calculates a qualifying parcel's property tax on its agricultural or forestry use value, not on what a buyer would pay for it on the open market. More than 12 million acres are enrolled statewide, according to the Pennsylvania Department of Agriculture. The important thing for buyers to understand is the rollback provision: if land use changes after purchase, back taxes can reach seven years into the past and include 6% annual simple interest on the difference between the program rate and the full market assessment. Confirming a parcel's enrollment status before making an offer is essential, not optional.

How does zoning affect what I can do with land in Lehigh Valley?

Each municipality in the Lehigh Valley sets its own zoning rules, so permitted uses, lot-size minimums, density limits, and setback requirements vary from one township to the next. Residential, agricultural, commercial, and mixed-use designations each define what can legally be built or operated on a given parcel. Buyers considering land within Allentown city limits should pay particular attention: the city's updated Zoning Ordinance took effect January 1, 2026, and introduces a genuinely new regulatory framework that replaces all prior maps and district definitions.

What are the closing costs specific to a land purchase in Pennsylvania?

Beyond standard title and recording fees, Pennsylvania's realty transfer tax adds up to 2% of the purchase price in most municipalities: 1% to the commonwealth and 1% to the local government. Survey costs, perc testing fees, and any environmental assessments are typically paid during or before the due diligence period. If the land does not yet have utility connections, tap-in or extension fees are a separate line item that should be estimated before you commit to a price.
