What people are saying
Types of In law Suite Additions
interior Addition
Interior in law suite additions convert existing space within your home into a private living area, using the current footprint and structure. They are ideal for basements, upper floors, or unused rooms where independence is needed without building outward.
Attached Addition
Attached in law suite additions are built onto your home with a shared wall, creating a dedicated living space that stays connected. They are ideal for close family living, offering privacy while maintaining convenient access to the main house.
Detached Addition
Detached in law suite additions are separate structures built on your property, providing maximum privacy and independence. They are ideal for long-term guests, rental potential, or multi-generational living that benefits from complete separation.

In most Maryland and Virginia counties, in-law suites can include a private kitchen and bathroom, but Washington DC has stricter accessory dwelling regulations. Design must comply with local zoning codes, utility requirements, and occupancy rules to avoid delays or violations.
In-law suite additions typically start at $100,000+, depending on size, structure type, foundation needs, and interior finishes. Costs increase for detached suites, full kitchens, separate entrances, and upgraded accessibility features like zero-step entry or wider doorways.
In-law suites can be built as a ground-floor addition, over a garage, in a finished basement, or as a detached backyard structure, depending on zoning and lot size. Local setback requirements, lot coverage limits, and utilities determine what options are allowed on your property.
