Fire separation & safety basics for ADUs
Safety and separation rules are an important part of ADU design.
Building and fire codes often require certain wall ratings, door types and distances between units to slow the spread of fire.
Rated walls and doors
Where the ADU is close to property lines or other structures, rated walls and doors may be required.
Smoke alarms and egress
ADUs must provide safe ways out in an emergency and interconnected smoke alarms.
We coordinate with designers and local officials so safety requirements are handled early instead of becoming surprises later.
