Reading the actual guideline text below — never a general AI guess

Garage Door Auto-Reverse Safety

Here's what the passages actually address: The excerpts shown here do not cover the technical safety standards for garage door auto-reverse mechanisms themselves. What *is* covered relates to how lenders and appraisers handle garage doors during property transactions and inspections—specifically that inoperable garage doors must be repaired or replaced, automatic openers should be disconnected during mortgage servicing, and the number of parking spaces created by garage doors (whether single or double) must be counted and reported in appraisals. The passages also note that carbon monoxide can seep into living spaces from an attached garage through doors and unsealed openings, which is why detectors are required for attached garages with communicating openings to the home.

For the specific safety requirements about auto-reverse mechanisms and sensors themselves, those details are referenced in the 16 CFR Part 1211 and UL 325 standards cited, but the actual technical specifications from those documents are not shown here.

Straight from HUD/FHA Single Family Handbook 4000.1, UAD 3.6/URAR, and IRC R315 — nothing added.

UAD 3.6 adoption and FHA guidance on garage conversions

FHA HB 4000.1 (pages 499–500) provides current guidance on treatment of garage conversions in appraisals, with criteria for counting converted space as GLA that do not explicitly require permits—relevant to understanding when to include or exclude unpermitted conversions.

Permitted vs. Unpermitted Garage Conversions: ROI Data for 2026

This source discusses that permitted garage conversions typically increase home value by 10-30% with ROI of 60-80%, while unpermitted conversions can decrease value by triggering lender refusals and appraisal exclusions.
