Is Your Pennsylvania Property Suitable for Townhome Development? 

A Strategic Guide for Landowners Considering Residential Development

Across Pennsylvania, one of the fastest growing forms of residential development is townhome communities.

From suburban Philadelphia… to the Lehigh Valley… to the expanding suburbs of Pittsburgh… Townhomes have become one of the most popular housing products in the state.

For landowners, this raises an important question:

Could your property support townhome development?

Many landowners assume their property is only suitable for large-lot homes or farmland. In reality, if the right conditions exist, land that once supported one home per acre could potentially support six to ten homes per acre as townhomes. That increase in density can dramatically change land value.

This guide explains how to determine whether your Pennsylvania property may be suitable for townhome development.

Why Townhome Development Is Increasing in Pennsylvania

Townhome construction has expanded across Pennsylvania for several reasons.

Housing Affordability

Single-family home prices have increased significantly in many markets. Townhomes provide a more affordable option for buyers.

Land Scarcity

In growing regions, large parcels near infrastructure are becoming harder to find. Townhomes allow developers to build more homes on less land.

Buyer Demand

Many buyers prefer:

• smaller yards
• lower maintenance
• suburban locations near jobs and shopping

Townhomes meet this demand.

Demographic Shifts

Townhomes appeal to:

• first-time buyers
• downsizing homeowners
• young professionals
• empty nesters

Because they appeal to multiple buyer groups, developers often seek land suitable for this type of housing.

What Is a Townhome Development? 

A townhome development typically consists of attached residential units arranged in rows or clusters.

Each unit usually includes:

• multiple floors
• private entrance
• small yard or patio
• shared community infrastructure

Townhome communities often include:

• internal roads
• sidewalks
• shared open space
• stormwater management systems
• homeowners associations

Townhomes allow significantly higher density than traditional subdivisions.

Typical Townhome Density in Pennsylvania

Townhome density varies by municipality, but typical ranges include:

Low-Density Townhomes

• 4–6 units per acre

Medium-Density Townhomes

• 6–10 units per acre

Higher-Density Townhomes

• 10–14 units per acre

These densities are much higher than traditional suburban subdivisions.

For example:

• Traditional subdivision → 2 homes per acre
• Townhome community → 8 homes per acre

That difference can significantly affect land value.

Key Factors That Determine Townhome Development Potential

Not every property is suitable for townhomes. Several critical factors influence whether developers would consider the land.

1. Sewer and Water Availability

Townhome developments almost always require public sewer and water service. Without sewer, density is typically limited because septic systems require large lots.

Properties most attractive to townhome developers are usually:

• within sewer service areas
• near existing water infrastructure
• adjacent to suburban neighborhoods

Utility availability is often the first factor developers evaluate.

2. Zoning and Density Regulations

Municipal zoning determines whether townhomes are permitted.

Common zoning districts that allow townhomes include:

• Medium-density residential
• Planned residential development (PRD)
• Mixed-use districts
• Multifamily zoning districts

Some municipalities allow townhomes only through conditional use approval or rezoning.

Understanding zoning regulations is critical when evaluating development potential.

3. Location Near Employment Centers

Townhome demand tends to be strongest near employment centers.

In Pennsylvania, major housing demand corridors include:

• Philadelphia suburbs
• Lehigh Valley (Allentown-Bethlehem-Easton)
• Pittsburgh metropolitan suburbs
• Harrisburg and the I-81 corridor
• Lancaster and York regions

Land near these economic centers is often attractive to residential developers.

4. Access to Major Transportation Routes

Developers prioritize properties near major transportation corridors.

Important Pennsylvania growth corridors include:

• I-76 (Pennsylvania Turnpike)
• I-78 (Lehigh Valley corridor)
• I-81 (Central Pennsylvania logistics corridor)
• I-79 (Western Pennsylvania growth corridor)
• I-95 (Philadelphia metro region)

Convenient access to these highways increases housing demand.

5. School District Quality

School districts significantly influence residential development decisions.

Strong school districts often increase:

• housing demand
• home sale prices
• development feasibility

However, school district quality may matter less for 55+ townhome communities, which target older buyers.

6. Site Size and Layout

Townhome developments usually require parcels large enough to accommodate: internal road systems stormwater infrastructure open space requirements

Many townhome developments are built on parcels ranging from:

• 10 acres to 100+ acres.

Smaller parcels may still support infill townhome projects in urban areas.

7. Topography and Environmental Constraints

Pennsylvania’s terrain can affect development feasibility.

Common constraints include:

• steep slopes
• wetlands
• floodplains
• rock excavation
• stormwater management challenges

Developers prefer sites with manageable topography and minimal environmental restrictions.

Regions in Pennsylvania Seeing Townhome Growth

Townhome development is expanding in many parts of the state.

Southeast Pennsylvania

The Philadelphia suburbs remain one of the strongest townhome markets due to population density and land scarcity.

Lehigh Valley

Rapid growth and migration from New Jersey have increased demand for townhomes.

Pittsburgh Suburbs

Townhomes are becoming more common in growing suburban areas surrounding Pittsburgh.

Central Pennsylvania

Logistics growth along the I-81 corridor is driving housing demand.

South Central Pennsylvania

York and Lancaster counties continue to see steady residential expansion.

How Townhome Density Affects Land Value

Density plays a major role in determining land value.

Example: 20-acre property

Single-family zoning:

• 2 homes per acre → 40 homes

Townhome zoning:

• 8 homes per acre → 160 homes

The potential housing yield quadruples.

When yield increases, developers may be able to pay significantly more for land.

When Rezoning May Be Necessary

Some properties require rezoning before townhomes can be built.

Rezoning may involve:

• planning commission review
• public hearings
• municipal approval

If a municipality’s comprehensive plan encourages residential growth, rezoning may be feasible.

However, rezoning is not guaranteed and requires careful evaluation. 

Why Developers Seek Townhome 

Land Developers often pursue townhome projects because they provide:

• efficient land use
• lower infrastructure cost per unit
• strong buyer demand
• faster absorption in many markets

For these reasons, developers frequently search for parcels that can support this type of development.

Common Misconceptions Among Landowners

“My land is too rural for townhomes.”

If infrastructure is expanding nearby, rural land may transition to suburban development over time.

“Townhomes only work in cities.”

Many townhome communities are located in suburban areas.

“Only large parcels qualify.”

While larger sites are common, smaller parcels may work for infill development.

Frequently Asked Questions

How many townhomes can be built per acre?

• Typically 6–10 units per acre, though zoning regulations vary by municipality.

Do townhome developments require sewer?

• Yes, most townhome developments require public sewer and water service.

Is my farmland suitable for townhomes?

If sewer access, zoning flexibility, and housing demand exist, farmland may transition to residential development.

Do developers pay per acre or per lot?

Most developers calculate land value based on per-unit yield, not acreage.

Final Advisory Perspective

Townhome development has become one of the most important forms of residential growth in Pennsylvania.

For landowners, this creates an important opportunity. Land that once supported only low-density development may now support higher-density housing.

Determining whether your property is suitable for townhomes requires evaluating:

• zoning
• sewer availability
• density potential
• infrastructure access
• market demand

Understanding these factors helps landowners recognize when their property may have transitioned from rural land to development land.
