One crucial step that you should always consider in any construction project is obtaining a Certificate of Occupancy (CO). A CO is a legal document issued by the local government agency that certifies that a building complies with all regulations, safety codes and zoning requirements.
A building permit is generally required when changes or alterations are made to a residential building or when any new construction is undertaken. Mechanical and plumbing work also require permits and inspections. Electrical permits are obtained at Washington State Department of Labor and Industries.
Permit Center The building code states that each building shall have a Certificate of Occupancy specific to the type of business or activity occurring in the space. The Certificate of Occupancy must be issued prior to the new business occupying the space, regardless of whether or not a building permit is required.
A building permit shall not be required for the following: One-story detached accessory buildings used as tool and storage sheds, playhouses and similar uses, provided the projected roof area does not exceed one hundred twenty square feet. Fences not over six feet high. Oil derricks.
You have legal grounds to sue the previous owner if they failed to disclose unpermitted work. Real estate practices require sellers to disclose any known unpermitted improvements. If the previous owner intentionally hid this information, you might have a case for misleading real estate practices.
You don't need a permit to build a shed if it meets all of these criteria: The total area (or “footprint”) of the shed's roof is 120 square feet or less. The shed is a single-story building. The shed sits on a simple concrete slab, pier blocks, or soil.
If you build without a permit or fail to get a final inspection approval, we may fine you or take other enforcement action against you.
Exempt Structure - 200 Square Feet or Less. Important: The 200 square foot (or less) Exempt Structure may be constructed on a lot with or without a residence. If there is a residence on the same lot, you may build an exempt accessory structure up to 800 SF.
Do I need a permit to remodel a bathroom? You only need to apply for a remodel permit if you are moving walls, changing or tapping into existing plumbing or need the modification to be noted for banking (selling, purchasing, etc.) or other legal purposes.
