Tips
- Deck permits are charged per square foot ($25.00/sq.ft.) rather than off the general valuation table used for other building work.
- Window/door replacement with no structural modification is a flat $75.00 per structure/building — cheaper than the general valuation-based Building Permit Fee.
- The general Additional Plan Review fee ($100.00/hour, minimum half hour) applies if plans change after initial submittal.
- For additions/alterations to a single-family dwelling, MCA 50-60-106(2)(c) requires Laurel (certified under 50-60-302) to issue the permit or a written notice of plan disapproval within 10 WORKING days of submission when the completed state single-family-dwelling checklist is attached to the plans — the governing statutory review-timeline ceiling, as the city publishes no figure of its own.
