OK, I'm just a rusty-uncurrent, school-trained ICC building inspector, and the regs have changed since I was active/current.
Here's my .02 on driveways; delivery access problems are similar in nature to FD access problems.
I see a whole lot of rural homes that do not meet the standards for fire department access; the older or myopic-designs of rural homes may be intentional, through ignorance, or simply neglect.
NFPA 1144 (1140) is designed for protection of homes in wooded areas, but all of the access requirements are the same no matter where homes are located...FDs need access to do their jobs; 8'-10' clear space around the home, turn outs every 200? feet, minimum heights (16'), widths(12' I recall), cleared driveways, radius of curve, % of slope, spaced out buildings, cut backs of trees & shrubs, etc.
16' high fir limbs in the summer are 6' high with snow or ice.
The specs also inlude fire-resistive construction like double pane windows, T111 siding, blocking, etc.
Not aimed at the OP or anyone else, but driveways that can prevent a fire truck from reaching the home, will probably prevent a 30' box truck from doing the same.
The info is free & public; the pic is a sample.
PS, there are grants to help home-owners prepare, and insurance companies are watching from above.
I pray this helps.
