Frequently Asked Questions

What is the difference between an in-law suite and a guest room?

A guest room is simply a bedroom within your home. An in-law suite is a fully functional, self-contained living space, typically with its own bathroom, kitchenette or kitchen, living area, and often a private entrance. It’s designed to support independent, long-term living, not just overnight stays.

Can an in-law suite be added to my existing West Chester home?

In many cases, yes. An in-law suite can often be added as a home addition, created from an existing space like a basement or garage, or included as part of a larger renovation. The biggest factor is your municipality’s zoning rules.

While Pennsylvania lawmakers have proposed legislation that would make accessory dwelling units (ADUs) more widely available, there is currently no statewide law requiring municipalities to allow them. Whether an in-law suite or ADU is permitted depends on your local zoning ordinance. At Megill Homes, we’ll review your property’s requirements and help you determine what’s possible before moving forward with the design.

How long does it take to build a custom in-law suite?

Timelines vary depending on the scope and complexity of the project. Megill provides a clear schedule upfront and manages the process from permitting through completion, keeping you informed at every stage. During your initial consultation, they can give you a more accurate timeframe based on your specific project.

Does Megill handle permits for in-law suite projects in West Chester?

Yes. Megill manages the full permitting process on your behalf. Their familiarity with Chester County’s local regulations means they can navigate approvals efficiently and avoid common delays.
