The Mono County Building Division is responsible for the oversight and issuance of all building permits and associated work completed in the unincorporated areas of Mono County. We do not oversee or permit work within the Town of Mammoth Lakes. For more information about building within Mammoth Lakes, visit the Town's website.


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.


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.

Prescriptive Designs Plan2

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".
