Projects That Do Not Require Construction Plans
You will apply for a different building permit based on whether or not construction plans are required.
For the residential and non-residential projects listed under "Show More" below, construction plans are not required, so you will apply for a "Building Permit with No Plan Check." But please note: A site plan may still be required.
(All other projects not listed under "Show More" below will require construction plans, so you will apply for a "Building Permit with Plan Check.")
The following types of projects do not require building plans for residential structures and/or associated accessory structures:
- Plumbing work, including water heater replacement or installation (including associated water piping, gas piping, and vents)
- Electrical work (with a pre-existing meter). New solar (photovoltaic or thermal) systems require plans.)
- Electrical service upgrade (maximum of 200 amps including associated wiring)
- Mechanical work, including heating and/or cooling equipment repair or replacement (including associated water piping, gas piping, and vents)
- Re-roofing, including roof sheathing, fascia boards and rafter tails that are replaced as a matter of required maintenance
- Siding installation or replacement
- Wall: Dry rot repair and/or replacement in kind or other alterations to not more than 40 lineal feet of wall, provided the work meets the requirements for conventional construction in the building code. “Wall” includes bottom plate to top plate and may include rim joist, rafter tails and fascia (foundation repair/replace and re-framing of room rafters requires plans).
- Decks: Repairs to decking or guardrails
Because there are no plans, it is important that the permit description include enough information so that the building inspector can determine the extent of the work. All work must conform to present codes. (Example: Guardrails which are replaced must meet current spacing and height requirements. Stairs must comply with current rise and run requirements.)
For non-residential projects, the types of projects that do not require building plans are severely limited because, with some exceptions, when alterations or structural repairs are made to existing non-residential buildings, Americans with Disabilities Act requirements must be made as well.
The following types of projects do not require building plans for non-residential structures:
- Replacement heating, water heating, ventilation, and air conditioning equipment with the same type of unit in the same location. (New roof-mounted equipment or equipment in a new location requires plans. New solar (photovoltaic or thermal) systems require plans.)
- Re-roofing (reframing the roof requires plans)
- Electrical service upgrade (maximum 200 amps including associated wiring)
- Electrical work not involving the placement or replacement of switches or receptacles
- Plumbing work not involving the placement or replacement of plumbing fixtures
All other work for a non-residential structure requires plans.
