I had a detached garage when I lived back east. I didn’t have the key issue locking up the garage because I kept a garage door opener in my purse.
I had a baby in that house… and if I was carrying in the baby AND it was raining or snowing, I parked closer to the front door (garage was down a long driveway to the back of the lot)… that allowed me to unload stuff onto the covered front porch and have a shorter walk… Or I’d park right be the back porch (which was off the kitchen) – also covered.
It was part of the charm of a 1910 house.
Current house has garage close to kitchen… but further from the stairs to upstairs… when my younger son was an infant, I’d park close to the front door (which was near the stairs) if I needed to transfer a sleeping baby to his crib.
There is no perfect arrangement.
I agree with Hobie’s reasons.
Besides.. how many Californians actually park cars in their garage…? I think we’re the only ones on our block that have 2 cars in our 2 car garage.
