PLANNING DEPARTMENT  Information on CDA including: long-range planning; zoning and property information; applications fees and resources; projects under review; boards, commissions and public hearings; and plans, policies, and regulations. BUILDING DEPARTMENT Information on permits, building requirements, Accessory Dwelling Units (ADUs), Forms and Applications, Inspections, Permits and Fees, Architectural Commission. GREEN BUILDING REQUIREMENTS New state and local green building requirements went into place on January 1, 2020. If you were issued a permit prior to this date, then you are using past building requirements. For current projects after January 1, 2020, please use the current guides and checklists to comply with Title 19 Marin County Building Code, Subchapter 2 – Green Building Requirements.SUSTAINABILITY PROGRAMS FOR CONTRACTORS If you are a general, plumbing, HVAC, or insulation contractor, you can take advantage of training resources to expand your knowledge base and skill sets and participate in rebate programs to grow your business. If you have any questions about the programs and resources listed below, feel free to call the County at (415) 473-2698 or email energy@marincounty.org.DEVELOPMENT AND PERMIT FACT SHEETS A resource drafted by the County to respond to some of the most frequently asked questions.TREE REMOVAL FACT SHEET A Tree Removal Permit is required for the removal of trees in the following instances: • More than two (2) “Protected Trees” are being removed from a developed lot in a 12-month period; • The tree qualifies as a “Heritage Tree”; • The tree is a “Protected Tree” or “Heritage Tree” and is located in a Stream Conservation Area or a Wetland Conservation Area; • Any removal of “Protected Trees” on a vacant lot; and, • The trees proposed for removal do not qualify for an exemption under Section 22.62.040 of the Marin County Code.

PERMIT SEARCH & MAPPING

Do you have questions about a property or wondering if development in your neighborhood is permitted? Start Here! Use the Marin County GIS / Mapping tool to find the parcel number of the property. Use that parcel number to look up past and current permits. MARIN COUNTY GIS / MAPPING The County of Marin Geographic Information System (GIS) section creates and maintains a variety of applications, digital map databases and maps. GIS is a computer-based technology that digitizes, stores, organizes, analyzes and displays maps of anything that can be represented graphically. The mapped entities have “real world” coordinates directly tied to the earth’s surface, enabling easy viewing of the spatial relationship among mapped features.MARIN COUNTY CURRENT PERMIT LOOK UP Mapping platform for community members to view building permits and inspections by property or permit number. ** Note: This site indicates it is updated monthly. Some permits may not be listed. When in doubt, you can contact the County for assistance directly. MARIN COUNTY RECORDS SEARCH The CDA stores and makes available project information and permit history that may be helpful for property owners, business owners, and others doing research or considering a project. Includes Environmental Health Services, Building and Safety, and Planning.  ** Note: Not all records have been scanned. When in doubt, contact the County and you can make an appointment to search records directly if needed.

PERMIT CATEGORICAL EXCLUSIONS
Most development projects within the coastal zone require a Coastal Permit. However, the Coastal Commission has granted “categorical exclusions” to the County of Marin allowing certain categories of development to not require a Coastal Permit. Qualifying categories are within select geographical areas and subject to specific criteria, which are further described in the panels below. If your project is eligible for an exclusion from CP requirements, you will need to obtain a Coastal Permit Exclusion from the County prior to issuance of building, septic, or well permits.


code compliance

The CDA code compliance program ensures adherence with the County's laws and regulations related to zoning, construction, and environmental health. Use this link to report problems or concerns you have with potentially unpermitted development in your neighborhood.

 

ENVIRONMENTAL HEALTH SERVICES:
WELLS AND WATER SYSTEMS

WELLS AND WATER SYSTEMS Environmental Health Services strives to protect public health and safety by employing a preventive approach to assure that groundwater will not be contaminated with chemicals and/or bacteria. This approach includes the review and approval of permits for the drilling and construction of water wells, environmental monitoring wells, cathodic protection wells, and explorative soil borings.

ENVIRONMENTAL HEALTH SERVICES:
SEPTIC AND GRAYWATER SYSTEMS

SEPTIC SYSTEMS Onsite Wastewater Treatment Systems (OWTS) commonly referred to as septic systems should be managed to protect the public from disease and to protect ground and surface water resources from contamination. The primary function of an OWTS is to treat, reduce, or eliminate contaminants to reduce the threat to public health and the environment.GRAYWATER SYSTEMS Graywater is water from bathtubs, showers, bathroom sinks, washing machines, and laundry tubs. Graywater does not include waste water from toilets, urinals, kitchen sinks, dishwashers, photo lab sinks, or water from soiled diapers. It is not reclaimed water distributed through “purple pipes.” Graywater can be diverted from the sewer or septic system and used for landscape irrigation and constructed wetlands.

State of California

The State of California regulates development activities to protect habitat and ensure public health and safety. Below are some of state agencies and links to permits and application information.

COASTAL COMMISSION AND
LOCAL COASTAL PROGRAM

CALIFORNIA COASTAL COMMISSION The Commission is committed to protecting and enhancing California’s coast and ocean for present and future generations. It does so through careful planning and regulation of environmentally-sustainable development, rigorous use of science, strong public participation, education, and effective intergovernmental coordination.LOCAL COASTAL PROGRAMS (LCPS)  The basic planning tools used by local governments to guide development in the coastal zone, in partnership with the Coastal Commission. LCPs contain the ground rules for future development and protection of coastal resources in the 76 coastal cities and counties. The Commission’s coastal permitting authority over most new development is transferred to the local government, which applies the requirements of the LCP in reviewing proposed new developments. The Commission retains permanent coastal permit jurisdiction over development proposed on tidelands, submerged lands, and public trust lands, and the Commission also acts on appeals from certain local government coastal permit decisions.MARIN COUNTY LOCAL COASTAL PROGRAM The LCP is a planning document that identifies the location, type, densities, and other ground rules for future development in the coastal zone. Each LCP includes a land use plan and its implementing measures. These programs govern decisions that determine the short and long term conservation and use of coastal land, water, and other resources.COASTAL COMMISSION ENFORCEMENT The Enforcement Program works to ensure that all non-exempt development along the California coast, including in certain coastal mountains, undergoes the Act’s independent permit review process and secures the required Coastal Development Permit (CDP). The Commission's Enforcement Program also works to ensure compliance with all terms and conditions of CDPs previously issued by the Commission. In certain cases, the enforcement program also helps to enforce compliance with the Local Coastal Programs of local coastal governments and the Coastal Act.REPORT A VIOLATION:  North Central District: San Mateo, San Francisco, Marin, and Sonoma County.

CONTROL BOARD

STATE WATER BOARD The Water Board works to preserve, enhance, and restore the quality of California’s water resources and drinking water for the protection of the environment, public health, and all beneficial uses, and to ensure proper water resource allocation and efficient use, for the benefit of present and future generations. The State Water Board works in coordination with the nine Regional Water Boards to preserve, protect, enhance, and restore water quality. The State Water Board sets statewide water quality standards, issues statewide general permits, conducts statewide surface and groundwater monitoring and assessment, and issues orders for cleaning up contaminated sites.
