The resident was in stable condition, reported Jeff Hawke, director of the Grand Haven Department of Public Safety.
One of the homeowners, Scott Brown, said his mother-in-law, who is disabled, was taken to the hospital to be checked because of an elevated blood pressure.
Brown said he and three of the other occupants of the home at 403 Lake, helped his mother-in-law evacuate the home when the blaze in their garage was discovered.
Firefighters responded to 403 Lake Avenue at 1:52 a.m. and found the garage behind the residence fully involved in fire and two other garages beginning to burn.
Flames were also touching the homes located at 401 and 403 Lake Avenue.
Hawke said the fire was contained to the three garages. The houses sustained minor exterior damage from heat and flames.
Cold temperatures caused some problems with water lines, but the fires were eventually extinguished.
Assisting GHDPS at the scene were Grand Haven Township Fire Rescue, Ferrysburg Fire Department, Spring Lake Township Fire Department and Norton Shores Fire Department Canteen 450.
Paramedics from North Ottawa Community Hospital assisted with evacuating residents and provided medical support at the scene.
Hawke said there were no injuries associated with the fire.
GHDPS Fire Marshal Jay Paulson said late this morning they have been able to determine the area where the fire started, but are still investigating the cause.
"The fire appears to have started in an area in front of the woodstove, but the woodstove was not used," he said. "There are a lot of things we are looking at."
Paulson said a preliminary damage estimate would be at least a quarter of a million dollars.
That encompasses three destroyed garage, one damaged garage and some damage to two houses.
