Building permits expire by limitation if no work is performed or no regular inspection is called for within any 180-day period. A one-time, 180-day extension may be granted by the Building Official provided that a written request for extension is provided prior to the expiration of the building permit.
If a permit expires, a new permit and applicable fees will be required.
Most plan check and permit fees are based on the valuation of the project. The Building Division determines the valuation based on published valuation tables. The valuation is based on the value of the work, not the actual cost, of all the construction or work the permit is issued for. This includes all finish work, painting, roofing, electrical, plumbing, heating, air conditioning, elevators, fire extinguishing systems, paving, any other permanent work of improvement or permanent equipment, overhead and profit.
Please feel free to contact the Building Division if you need a rough estimate of the Building Permit fees prior to starting your project.
For more information about fees please see the handout "Obtaining a Building Permit."
The time it takes to approve a set of plans and documentation varies depending on a number of factors such as the complexity of the project, the completeness of the plans, the current workload of the Plans Examiner and the number of times the plans and documentation must be returned for corrections. The best way to expidite permit processing is to have the plans prepared by a qualified design professional.
For a standard new single-family dwelling, the average time it typically takes to approve plans and documentation is 6 to 8 weeks. Plan checking for minor projects are typically processed much quicker.
The Plans Examiner can provide you with a rough estimate of the plan review turnaround time when you submit your plans for plan check.
For more information, please see the handout "Obtaining a Building Permit."
Disabled access regulations are triggered when a building is newly constructed or when alterations, remodeling, structural repairs or additions are made to an existing building.
Projects that consist only of heating, ventilation, air conditioning, reroofing, electrical work not involving placement of switches and receptacles, painting and related cosmetic work or equipment not considered part of the architecture of the building do not trigger accessibility requirements.
Fire sprinkler systems must be installed under the following circumstances:
In other than Group U occupancies (i.e. garages, garden sheds, fences) and Group S Division 2 shipping containers, a fire sprinkler system is required in all newly constructed buildings.
ADDITION is the increase of area of an existing structure, for which a building permit has been issued, where the increase in floor area is not made exclusively for the provision of accessibility for the physically disabled. For additions to all existing structures that result in a building with a floor area (including porches, covered parking, attics with floors, storage rooms and other covered areas) greater than 4,000 square feet, a fire sprinkler system must be provided throughout the entire building.
REMODELING is work requiring a building permit including, but not limited to, cosmetic or structural repairs, renovations, restorations, alterations or additions to a structure, the total cumulative building permit valuation of which, as determined by the Building Official, exceeds $100,000 for residential uses and occupancies or exceeds $150,000 for all other occupancies over any 36-month period. All existing structures that are remodeled and meet the above-mentioned criteria require an automatic fire sprinkler system throughout the entire existing structure.
Additional Requirements for Additions to Existing Residential Structures
A fire sprinkler system is also required when any addition is made to a residential building and any of the following conditions exist:
1. Any part of the building is used as a hotel, motel, bed and breakfast, boarding house or any other form of transient occupancy.
2. Access to the structure does not meet the emergency vehicle access requirements of Article 9 of the Fire Code.
3. The structure will contain two or more dwelling or guest units.
4. The structure contains a use other than the residential component.
5. Water supply to the structure does not meet the water supply requirements of Article 9 of the Fire Code.
6. The structure is located on land that would be classified as “State Responsible Area” if it were not located in the City of Sonoma (i.e. hillsides).
For more information, please see the handout titled "Fire Sprinkler Requirements."
Public improvements are triggered for all projects with an aggregate permit valuation exceeding $40,000 over any 2-year period, except when the building permit is issued solely for reroofing, solar hot water heating or accessibility improvements to be installed in accordance with the Americans with Disabilities Act or other approved accessibility standard. Public improvements are curbs, gutters, sidewalks, streets and storm drainage and must be provided or repaired by the property owner as determined necessary by the City Engineer. The owner of the property must sign a public improvement agreement in conjuction with the permit and is responsible for the costs and installation of the public improvements in accordance with City Standards.
Public improvements can be expensive, so it is in your best interest to contact the City Engineer to determine the necessary requirements before filing an application for a building permit.
You can now begin construction. Your approved plans, job card and any other documents you received must be maintained on the job site for use by the inspector. The job card will be used by the inspector to record the progress of the required inspections. The set of plans will be used to verify that all construction is in compliance with the approved plans.
If the job card and plans must are not on-site and available for the inspector's use, no inspection can be performed.
For more information, please see the handout "Obtaining a Building Permit."

A Special Inspector is a third party, independent inspector hired by the property owner to inspect specific elements of a project(i.e. welding, structural bolting, high strength concrete, masonry, fireproofing, etc.)as prescribed by the building code. Special Inspection firms that have been recognized by the City of Sonoma for specific specific types of special inspections can be found on the City's list of Recognized Special Inspection Agencies.
A Building Survey is a service provided by the Building Department intended to provide an overview of requirements or issues that would likely come about as a result of a proposed change of use, remodel or addition to a building. This service is commonly used by prospective buyers or prospective tenants that are investigating the potential costs and code requirements for a building to facilitate a particular use or improvement. This service allows prospective buyers to obtain a general overview of necessary City requirements and develop cost estimates prior to actually purchasing a building or renting a tenant space.
The Building Survey includes an on-site inspection and a written report performed and prepared by City staff. While the Building Survey is not intended to identify all code deficiencies within a building, it is intended to identify some of the major costs that might be associated with a change in use, remodel or addition to a building. The cost for obtaining a Building Survey is updated annually and may be obtained by calling City Hall at 707-938-3681. Click on the following link for a Building Survey Application Form.
The installation of any new wood-burning appliance (i.e. fireplaces and wood stoves) within a building in the City of Sonoma where no wood burning appliance previously existed is prohibited.

For more information, see the handout titled "Wood Burning Appliance Regulations."
