Company
Who they are.
"Deliver more square footage and more standard features than competitors at the same price point — the 'Included Living' approach."
Keystone Custom Homes is one of the largest privately-owned homebuilders in Pennsylvania, Maryland, Delaware, and Virginia. Based in Lancaster County, the company builds primarily in master-planned production communities but also on scattered lots.
Their calling card is generous included features — the base price of a Keystone home typically comes with finishes that competitors sell as upgrades. Floor plans tend to be family-forward, with expansive great rooms and functional secondary spaces.

Frequently Asked Questions
What buyers ask us about Keystone Custom Homes.
Is Keystone Custom Homes actually a custom builder?
Despite the name, Keystone is a semi-custom production builder. You choose from a library of proven floor plans and personalize finishes and structural options — but you're not designing a home from scratch with an architect.
Where does Keystone build in Lancaster County?
Primarily in Manheim Township, East Hempfield, Warwick Township, Mount Joy, and the Elizabethtown area, with active communities also in Chester, Dauphin, and Lebanon Counties.
What's typical construction time?
Most Keystone homes close 6 – 9 months after contract, weather and supply-chain conditions permitting.
Are Keystone homes energy efficient?
Keystone builds to modern energy codes with tight envelopes, high-efficiency HVAC, and options for enhanced insulation packages.
Do I have to use Keystone Home Mortgage?
No — you can use any lender. However, buyer incentives are typically tied to using the affiliated lender.
What warranty comes with a Keystone home?
One-year full workmanship, two-year mechanical (HVAC, plumbing, electrical), and ten-year structural.
Can I bring my own real estate agent?
Yes. Your agent must be registered on your first visit to the community.
How large are the design studio selections?
Buyers typically spend 8 – 15 hours across multiple appointments choosing finishes, upgrades, and structural options.
What if I want to move a wall?
Wall moves are limited to pre-engineered structural options. True architectural changes require a custom builder.
Can I do a pre-drywall walkthrough?
Yes — pre-drywall is a standard checkpoint alongside the final orientation walk.
Are Keystone lots included in base price?
Base pricing includes a standard lot in the community; premium lots (cul-de-sac, corner, larger, wooded backing) carry additional premiums.
Does Keystone build on my own land?
Occasionally, but their business model is optimized for master-planned communities, not scattered-site builds.
