Frequently Asked Questions About Building in Annville

Your Building Questions, Answered

Do you help with permits in Annville Township and Lebanon County?

Yes. We guide you through all required municipal approvals, zoning regulations, and site engineering steps specific to Annville and Lebanon County before construction begins.

What is the difference between a design-build firm and hiring an architect separately?

When you hire an independent architect, the design process is disconnected from the construction budget, which often leads to misaligned expectations. As a design-build firm, ISM Construction handles both the architectural design and the construction in-house, ensuring accurate pricing and seamless communication from day one.

How long does it take to build a custom home in Annville?

From the initial design consultation to move-in day, a custom home typically takes between 12 and 24 months. The construction phase itself usually spans 6 to 12 months once all permits are secured.

Can you build on land I already own in Annville?

Absolutely. We specialize in “build on your lot” projects. We will visit your property to assess the terrain, evaluate soil conditions, and determine the best orientation for your new home.
