Welcome to RMA

The Resource Management Agency strives to ensure that its customer service standards are consistent with the Agency’s Mission Statement:

The mission of the Resource Management Agency, in cooperation with the public and our partner agencies, is to protect the consumer and community’s health, safety and environment by carrying out adopted laws and policies, and educating, assisting and empowering Ventura County residents and businesses to be good stewards of the land and our resources.


In addition, RMA has identified those core values which will guide us in carrying out our mission. These values are directly related to our customer service and include:

  • Honesty, hard work and ethical behavior

  • Transparency and accountability

  • Equitable treatment and respect of all constituents

  • Excellence in service delivery

The primary intent of Building regulation is to provide reasonable controls for the construction, use and occupancy of buildings and all of their various components. Thus such codes are minimum in nature, and under the provisions of the POLICE POWER cannot legally be made to require construction of a quality excessive of that which is necessary to furnish a reasonable degree of safety.  For details, see our permit processing guide.
