Model-specific evidence
R-22348 gives the site a real compact-model reference instead of making the one-bedroom option feel like a generic alternate size. That helps buyers compare the 1L path against the 3L path with a clearer source trail.
Structural engineering snapshot
R-22348 1L one-bedroom ADU structural information.
A focused engineering-education page for the compact 1L path: approval criteria, wind-pressure sheet, ETABS analytical model, rendered structural model, live/wind displacement outputs, and the same site-specific foundation boundary.
Compact model, serious review
The 1L page should not feel small just because the model is smaller.
The one-bedroom path is easier for buyers to imagine as a backyard rental, guest unit, parent suite, or compact housing solution. That does not make the engineering story optional. The R-22348 packet includes a visible approval path, component and cladding pressure references, ASCE 7-22 wind calculation material, ETABS analysis output, and structural model snapshots.
For a buyer, the value is clarity. The page explains what the engineering packet can help with, what still belongs to the local site team, and how a compact model should be priced without hiding foundation, utility, and permit work behind the product image.

What this proves
The 1L packet supports due diligence before the site visit.
Load path awareness
Wind, seismic, live, dead, and snow-load discussion appears in the packet. The site translates that into buyer language: structure is part of the product story, but local conditions still decide the project-specific engineering follow-up.
Installed-cost honesty
A smaller model can reduce some product and finish costs, but local fixed costs may remain meaningful. Utility distance, foundation design, access, fees, and setting can still move the total installed budget.
Calculator use
How the 1L structural page should guide the buyer.
Use the 1L page before the calculator when the buyer is comparing a compact ADU against a larger model. The engineering evidence makes it easier to keep the quote complete: product package first, then local site factors, then contingency until the real lot is reviewed.
Select the 1L pathUse the compact model path when the goal is a smaller rental, guest unit, caregiver suite, or constrained-yard option.
Do not erase fixed costsPermits, utility runs, setting access, and some foundation work may not shrink in a straight line with square footage.
Review wind and exposure assumptionsThe packet references wind and exposure criteria; a final project still needs confirmation for the actual placement and jurisdiction.
Confirm support conditionsLocal foundation and anchorage details should be reviewed as local project scope, not assumed from a factory packet alone.
Keep source PDFs availableA contractor, designer, or engineer can use the PDF packet as a starting reference during quote review.
Protect the buyer from a thin quoteIf a line item is not known, keep it visible as an allowance or gap rather than absorbing it into the factory package.
Truth boundary
Informative, source-backed, and still site-specific.
