In-Law Suites

An in-law suite can create a comfortable, private living space for family while keeping everyone close. Purpose Built Engineering helps homeowners plan attached and detached suites that work with the property, existing home, intended use, and local permitting requirements.

  • Multigenerational living

  • Attached home additions

Our Process

We review the property, intended use, and living-space needs to create a clear path from the initial review to final documents.

Review → Property Requirements → Plans → Permit Support → Final Documents

What to Expect During the Process

Every property and family’s needs are different, but most in-law suites follow the same general path. Open each step to see what to expect.

  • We begin by reviewing how the space will be used, whether it will be attached or detached, and which features are needed. Available surveys, existing plans, photographs, and property information can help us understand the scope.

  • We review factors that may affect the proposed suite, including zoning, setbacks, available space, utilities, flood-zone requirements, and any limitations on secondary living areas.

  • We prepare the plans and engineering details needed for the proposed space. This may include the layout, structural design, connections to the existing home, accessibility features, and coordination of building systems.

  • The completed documents can be submitted to the appropriate city or county for review. If clarification or revisions are requested, we help address comments related to our plans and engineering work.

  • Once required revisions are completed, the final documents are prepared for permitting and construction. The approved use of the space must remain consistent with local requirements.
