What this is
The Build Sheet publishes reference material on how houses get built: factory built housing, planning and budgeting, structure, the building envelope, and the mechanical and electrical systems. Alongside it there is a journal of longer pieces about why the industry works the way it does.
Every page is organised as a sheet, with a code, a revision date and a count of the sources it rests on. That is not decoration. It is a commitment that each page can be checked: the sources are named at the foot with the date they were read, and any figure in the text traces back to one of them.
What it does not do
It does not build, design, sell or deliver housing, and it does not sell anything to readers. It carries no display advertising and no affiliate links, and it takes no commission on anything a reader goes on to buy.
It also does not tell you what your building must comply with, and that restraint is the most important thing on this page. Building, energy, mechanical and electrical codes are adopted and amended locally in the United States, so requirements differ between neighbouring jurisdictions and between editions. Every page here explains what a requirement means and then sends you to the authority having jurisdiction for the value that governs your project. A site that gave you the number instead would be wrong somewhere and trusted everywhere. The journal piece on code adoption sets out why in full.
Who writes it
Pieces are published unattributed, under the publication, which is how most trade and reference publications handle bylines and raises no eyebrows. No author personas are invented, and no credentials are claimed on anyone else's behalf. Where a guest contributor writes something, it carries their own name.
The method matters more than the byline in any case, and it is documented in full on the standards sheet: which sources are acceptable, what happens when a document cannot be obtained, and how corrections are handled.
What to do with it
Use it to arrive at a conversation better prepared. The pages are written so that an owner can ask a builder, an engineer or a building official a question that gets a useful answer, and can recognise when an answer has skipped something. They are not a substitute for any of those people, and on anything touching gas, water, electricity or structure they are explicitly not a substitute for a licensed professional.
