Types of ADUs

Detatched

Detatched ADUs are typically new construction separate from the house and are often the first option people want to explore

  • Good for sound isolation and privacy

  • Requires the most amount of land

  • Requires the fewest changes to the existing house

Attached

Adding on to a house to create an ADU can work great on lots that still have room, but not enough for a detached solution

  • Requires fire rated construction between the main house and ADU

  • Placement is important to preserve privacy and identity

  • Will require modifying the existing house

Garage Conversion

Garage conversions are often one of the first options discussed, but they need to be carefully considered

  • Potentially the most cost effective

  • Plumbing can be complicated

  • Floor must be sealed and insulated

  • Storage for both main house and ADU must be addressed

  • Must modify the house for fire-rated construction separating the main house from the ADU

Above Garage Addition

Building above a garage is a great way to separate the main house and ADU using the garage as a buffer

  • Good solution where land is limited

  • Requires modifying the existing building

  • Fire-rated construction requriements can get complicated

  • Access and entry into the ADU can be a challenge

Attic or Basement Conversion

Sometimes the best solution is to convert an underused portion of the main home. The best approach for this is not always obvious

  • The most intrusive project type during construction

  • Success is highly dependent on existing circumstances and layout

  • Will most likely require a great deal of modificaiton to the existing house

  • Fire-rated construction for separation and support structure could be very complicated
