- Painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work.
- Decks and platforms not more than 30 inches above adjacent grade and not attached to a structure with frost footings. Manufactured homes require a permit for all decks. It is important to consider zoning ordinances and homeowners' association’s requirements when constructing a deck.
- Installation of roof gutter systems (downspouts shall not be directed to adjacent properties).
- Installation of soffit, fascia, trim, and other accessories.
