R-22345/R-22348 PDFs
Why this page belongs on ADU Cost
Most ADU cost sites talk about floor plans and price. Serious buyers also need to know that energy, ventilation, plumbing, electrical, and equipment notes can affect a real quote. The R-22345 and R-22348 text includes references to ventilation, heat pump equipment, water piping insulation, plumbing fixture requirements, electrical readiness, and 2025 residential mandatory requirements. Those details are not glamorous, but they are exactly what separates a thin estimate from a professional scope conversation.
How to explain code notes safely
The page should not pretend to be a code manual or a local plan-check approval. It should explain that the PDFs contain code-related notes a project team can review, and that local designers, contractors, inspectors, and authorities still control the project-specific implementation. The value is buyer education: these notes tell the buyer which questions belong in the quote packet.
How it affects cost
Energy and mechanical requirements can influence equipment selection, electrical capacity, panel space, water-heating configuration, ventilation strategy, ducting, penetrations, insulation, commissioning, and inspections. When those items are invisible, a low price looks better than it really is. When they are visible, ADU Cost can attract better leads because the buyer understands why the estimate is structured.
What a buyer should collect
The buyer should collect the model path, equipment schedule, energy documentation, ventilation approach, utility-distance notes, electrical panel information, water-heating selection, plumbing connection plan, and any local correction comments. These details can be attached to the calculator record so the final quote is built around known facts instead of assumptions.
How this creates better traffic.
Search traffic is only valuable when it brings the right buyer. A thin ADU page attracts people who only ask for a number. A PDF-based page attracts people who are already thinking about approval evidence, finish proof, local permit boundaries, energy notes, equipment scope, and installed-cost risk. Those buyers submit better notes and are easier to qualify.
That is why the page links into the calculator rather than ending with a vague sales pitch. The reader can turn the document into a working estimate by keeping known costs, unknown allowances, and source-proof questions separate.
