Permit takeaway

If a project does not appear on the county's exempt-work list, homeowners should assume a permit is required and contact the county if they are unsure.

Zoning and placement

Decks, pools, grading, additions, and exterior work can raise setback, drainage, parcel, site, and inspection issues even when the building scope seems simple.

Building and trade review

Residential inspection checklists include deck, footing, foundation, grading, lath, close-in, final, insulation, weather barrier, and pool inspection items.

Call before applying when

Call before applying if the project includes a deck, pool, footing, foundation repair, grading change, close-in work, exterior framing, weather barrier, or utility connection.
