Open portalPortsmouth’s Inspection Department reviews and approves building, electrical, plumbing, gas, septic, and mechanical plans and issues building permits and change-of-land-use permits. Planning and land-use boards are administered through the Inspection and Planning departments. The City’s municipal authority applies to Portsmouth addresses; Rockingham County does not operate a substitute building-permit office for the city.
Portsmouth ViewPoint Cloud permits
Portsmouth processes building permits online through ViewPoint Cloud. The City says the six building-permit types are consolidated into one application, while plumbing, mechanical, electrical, and fire permits remain separate applications. ViewPoint allows applicants to submit plans, monitor status, and receive email notifications. Use the application type that matches the project, including new construction, renovation, tenant fit-up, change of use, or temporary structure.
Inspections and certificate of occupancy
The Inspection Department schedules rough and final inspections and requires a certificate of occupancy before a building is occupied. For a new business or change of use, Portsmouth’s official guidance directs applicants to use the Tenant Fit-Up application and coordinate building, fire, health, and any required planning approvals. Call the office to cancel or reschedule an inspection rather than assuming an online submission changed the appointment.
Zoning and historic-district review
Portsmouth’s zoning review is important at the beginning of the permit process. Exterior work in a Historic District zoning area may require Historic District Commission review, and signs are governed by the City’s zoning ordinance. Confirm zoning, HDC, Planning Board, or Board of Adjustment requirements before construction documents are finalized.

Field work & closeout
Building Inspections & Code Compliance in Portsmouth
Most permitted work must remain accessible for inspection at defined stages. Before scheduling, check your permit record for the required inspection sequence and make sure the site is safe and ready. Final inspections can be especially important for code compliance and a certificate of occupancy.
Helpful preparation
Keep the permit card or approval number available, confirm the property address, and ask the official office about lead times or reinspection fees.
Planning & review
Zoning and Plan Review Requirements
A building permit is not always the only approval your project needs. Zoning guidelines may affect use, setbacks, height, parking, signage, or lot coverage. Residential and commercial building permits can also follow different plan review tracks, so confirm the correct path before investing in a full plan set.
For a project in Portsmouth, start with the official department below and ask which zoning, planning, conservation, or fire review approvals apply to your address.
