The minimum, and what we'd actually build.
Building code is the floor, not the goal. Every chapter gives you both: the code number your inspector will check, and the good number that makes the room work for the people in it.

Kitchens
A kitchen is a place to store, wash, prep, cook and gather. It works when the layout, cabinets, counters, light and services are planned together, around how you actually cook.

Bathrooms
A bathroom is more than tile and fittings. It's layout, measurements, water, drainage, waterproofing, air and light, all working together in a small, wet room.

Stairs + halls
Stairs are the most precise thing in a house. Small differences in risers and treads are what trip people, so code is exact.

Every job, the same questions come up. How wide should this aisle be? How high does that outlet go? What does code actually require, and what should we do instead? The answers are scattered across code books, spec sheets and the heads of good tradespeople.
Home Fieldbook puts them in one place, drawn so you can see them.
Good to know.
Who is it for?
Anyone making decisions about a building: homeowners planning a build or renovation, investors scoping a project, and the trades doing the work.
Which code does it follow?
The current model codes most US towns adopt: the 2021 International Residential Code, 2023 National Electrical Code and related I-codes. Your town may use a different edition or local amendments, so always check with your building department.
Is this a substitute for an architect or inspector?
No. It's a reference to help you understand the rules and ask better questions. Your local code official has the final say.
What do I get with Lifetime?
