WHEN IS A BUILDING PERMIT REQUIRED?
Permits are required when there is new construction to a building as well as some repair work or alterations to an existing structure. In addition, when a building is to be remodeled, renovated or enlarged, a permit will be required. New work consists of any new construction, commercial or residential, from vacant ground to a completed new structure. Projects that are considered cosmetic, such as painting, carpeting, adding new wallpaper, cabinets, and trim work, do not require a permit. If you have any questions concerning your specific project, please feel free to contact us.
WHY DO I NEED A PERMIT?
There is often concern about the purpose of and need for building permits. Building permits are mandated by state codes that regulate building, fire, mechanical, plumbing, electrical and other facets of construction. The building permit process provides a system to verify that plans comply with codes and the ability to investigate and examine work during construction. This process helps ensure a safe and quality final structure.
Complete building permit application: Use this application for projects such as new single-family residences, new commercial buildings, additions and detached structures. These applications also provide questionnaires for Encroachment permits, Grading Permits, Well permits, and Septic permits. It is highly recommended that applicants contact building division staff to discuss submittal requirements.

The Mono County Board of Supervisors has approved a resolution to waive permit fees for energy efficiency and alternative energy projects. Qualifying projects are residential and commercial solar, and ground-source space and water conditioning systems with a maximum project valuation of $75,000 each.
Mono County provides construction document resources known as "prescriptive designs". A prescriptive design is defined as "specific detailing requirements and similar pre-defined design options and rules used to create a code-compliant design. To the professional familiar with the process and standards, prescriptive design approaches are relatively fast to use without performing significant job-specific calculations".
