Billings Montana Deck, Shed, and Solar Permit Guide

Billings provides residential forms and guides for decks, sheds, garages, egress windows, re-roofing, homeowner electrical acknowledgement, and solar photovoltaic plan requirements.

Permit takeaway

Billings lists decks among work requiring a building permit, while detached sheds not exceeding 200 square feet are listed among work that does not require a building permit.

Zoning and placement

Detached sheds and deck locations should still be checked for setbacks, lot coverage, easements, and zoning limits even when a small shed is exempt from building permit review.

Building and trade review

The city publishes residential resources for deck handbooks, shed forms, garages, egress windows, re-roofing, and solar photovoltaic system plan requirements.

Call before applying when

Call before applying if the deck is attached or elevated, the shed is near 200 square feet, solar is being installed, or electrical work may need a separate permit.
