What is an In-Law Suite?

An in-law suite (also called a mother-in-law suite or in-law apartment) is a separate living space within or attached to your main home that includes a bedroom, bathroom, and basic kitchen facilities. Unlike a simple guest room, an inlaw suite provides complete independence with private access while remaining connected to the main house.

Common Types of In-Law Suites in Media, PA:

  • Basement conversions – Converting existing basement space
  • Garage conversions – Transforming attached or detached garages
  • Home additions – Building new space onto existing structure
  • Accessory dwelling units (ADUs) – Separate structures on the same property
  • Master suite conversions – Repurposing existing rooms

Why Media Families Choose In-Law Suite Additions
