Fee schedule

Sign (flat fee)Town of Darby Building Permit Fee Schedule (Res. 649, updated 4/13/2021), Miscellaneous Permit Fees table. Re-extracted and cross-checked directly from the source PDF on 2026-07-22 using two independent extraction methods (pdftotext -table and pdftotext -raw), both of which pair 'Sign' with $50.00 and 'Change of use' with $75.00 -- the opposite of the $75.00/$30.00 pairing recorded in this same file's residential-building-permit entry (lastVerified 2026-07-03), which appears to have resulted from a row-misaligned read of the same PDF's column layout via a third extraction method. This entry uses the freshly re-verified pairing; the residential-building-permit entry was left untouched per this task's scope (edit exactly one permitTypes addition batch, no existing entries modified) and should be corrected in a follow-up pass.

    Tips

    • A sign is not a separate permit type in Darby's own paperwork -- it is a $50.00 flat-fee line item on the same Building Permit Fee Schedule used for re-roofing, siding, demolition, and change of use.
    • No dedicated sign ordinance (size, height, setback, illumination standards) was found published on the Town's website; confirm specific sign design standards directly with Town Hall (101 E Tanner Ave / PO Box 37, Darby, MT 59829, (406) 821-3753) before fabricating or installing a sign.
