Right now it is 74 km (not miles) an hour with gusts up to 102 km per hour. At what point is it a huricane. The house kinda shakes now and than. I just moved here so I don't know, is this normal for living by the ocean?

That's not qualified as a hurricane.
From the National Oceanographic and Atmospheric Administration (USA):
From the last line of the first paragraph: "Note that all winds are using the U.S. 1-minute average."
Category One Hurricane:
Winds 74-95 mph (64-82 kt or 119-153 km/hr).
Category Two Hurricane:
Winds 96-110 mph (83-95 kt or 154-177 km/hr).
Category Three Hurricane:
Winds 111-130 mph (96-113 kt or 178-209 km/hr).
Category Four Hurricane:
Winds 131-155 mph (114-135 kt or 210-249 km/hr).
Category Five Hurricane:
Winds greater than 155 mph (135 kt or 249 km/hr).
This is called the Saffir-Simpson Hurricane Scale
It does qualify as a tropical storm (from the glossary):
Tropical Storm:
A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) ranges from 34 kt (39 mph or 63 km/hr) to 63 kt (73 mph or 118 km/hr).

No ;if the wind speed is equal to or more than 119 km per hour,then it is called as a hurricane.

i wouldn't be worried about 75 km wind. it should be a problem is trees, roofs and maybe street signs are being ripped apart. if you ask me, 75 km on a hurricane scale is probably a Grade 3 on a Grade 5 scale.
no worries
