Plan Review Services

Plan review is an important first step in ensuring that all new constructions, additions and alterations to buildings and structures are properly designed and constructed to meet the latest edition of the California Building Code Standards (“Codes”) requirements.

Plan review ensures that the minimum requirements of the Codes will provide a reasonable level of safety, public health and general welfare through structural strength, means of egress facilities, stability, sanitation, adequate light and ventilation, energy conservation, and safety to life and property from fire, explosion and other hazards, and to provide a reasonable level of safety to fire fighters and emergency responders during emergency operations.

Every permit application for a construction project must be accompanied by a construction document and submitted to the Development Permit Center to commence the plan check process.

Plan Review Requirements

The following are minimal information required to be included as part of a submitted construction document. This reflect the basic plans that are required to conduct a plan review for Building. For other plan check type (e.g., Fire, Electrical, Plumbing, Mechanical, Health, etc.) and related information to include on construction documents, refer to the Information Bulletins for additional plan submittal guidelines for each type of review group.

    1. Minimum Size
      • Plans must be at least 18 inches x 24 inches in size.
      • Plans must be scaled to no less than 1/4 inch per foot.
      • Plans must clearly indicate the location, nature, and extent of the work proposed.
      • Plans must show in detail compliance with all relevant laws, regulations, and codes.

    2. Plot Plan
      Every permit application for a construction project must be accompanied by a plot plan, drawn to appropriate scale on a form provided by the Department. Please complete FORM-028 Plot Plan and include as part of the plan submittal. View a sample of a plot plan.

    3. Site Plan
      A site plan shows the proposed or existing location of the building(s) and/or structure(s) and the proposed use(s) for a specific parcel of land(s) and adjoining use(s). View a sample of a site plan

      Site plan must contain the following specifications:
      • Lot lines and dimensions
      • Location of existing and proposed buildings properly dimensioned from property lines
      • Location of buildings and number of stories on adjoining lots
      • Uses of adjoining lots
      • All parking and loading facilities showing dimensions of stalls, access, circulation, docks, ramps, curb cuts, and fences
      • Locations of all trash containers
      • All existing and proposed easements
      • All setback lines, properly dimensioned
      • All contiguous and adjacent properties, street, and alleys, showing centerline and both curb lines, street widths, right-of-way lines, and street names
      • Lot size, lot coverage, building area (by floor), and total floor area to lot size ratio
      • Must be to scale with north arrow
    1. Floor Plan
      A floor plan is a diagram that shows general layout of the building, space(s) or room(s), including the use of each space(s) or room(s). It must include but not limited to the following: proposed and existing walls, partitions, doors, windows, and utility related fixtures or equipment. View a sample of a floor plan.

    2. Roof Plan
      A roof plan is a drawing that depicts the roof pitch, roofing material, drainage pattern, eave overhang, and gutters, as appropriate.

    3. Elevation Plan
      An elevation plan is a drawing showing the exterior sides of a building or structure to reflect the exterior wall finish, finish floor elevations, plate heights, adjacent grade elevations, dimensioned from the roof peak to ground, and generally includes all sides of the building or structure, as appropriate. Photographs may be substituted for elevations for existing buildings, as determined or allowed by staff. View a sample of an elevation.

    4. Landscape Plan
      A Landscape Plan consists of two parts:
      Planting plan: Shows the species, sizes, and locations of all plants
      Irrigation plan: Shows the layout of the sprinkler system and includes the sizes of pipes and spacing of sprinkler heads.

    5. Foundation Plan
      A foundation plan is a drawing that depicts the proposed or existing continuous and pad footings, the size and location of anchor bolts and hold downs, and other relevant structural information to show the support of the building or structure.

    6. Framing Plan
      A framing plan is a drawing that depicts the size and spacing of proposed or existing roof rafters, ceiling joists, floor joists, beams, columns, shear walls and other relevant structural information to show how roof and floors are supported to resist gravity and lateral loads.

    7. Cross Section Plan
      A cross section plan is a drawing that depicts the interior elevation of a building or structure, reflecting the full height and width of the building or structure, and cross reference information related to the framing, roofing and foundation details.

    8. Schedules 
      A plan that provide specification of the size and type of all doors, windows, roof and floor diaphragms, shear walls, and other pertinent equipment, hardwares or devices to be installed.

    9. Details
      A detail plan is a drawing that depicts all the construction details of how something is connected or assembled, cross-references where details are used throughout the floor, framing, foundation and/or cross section on the plans.

    10. General Notes and Material Specifications
      A plan that provides all the pertinent notes and material specifications.

The following information or document may be required in order to show compliance with the Codes or to substantiate a design or analysis. Those information or document may include, but not limited, to the following:

  1. Title 24 Energy
    This document should be provided to reflect a prescriptive compliance or performance calculations by a registered design professional along with CF-1R and MF1-R forms.

  2. Title 24 Accessibility
    The State’s Disabled Access requirements should be reflected on the site plan and floor plan.

  3. Structural Calculations
    This document should be provided to reflect the design, analysis and calculation of a building’s or structure’s vertical and lateral systems by a licensed and registered design professional.

  4. Soil/Geotechnical Reports
    This document should be provided to reflect the condition of the soil in supporting the weight of buildings or structures and the recommendations of the geotechnical engineer.

  5. Stormwater Management Program
    The construction documents and plans should show compliance with NPDES and SUSMP requirements, as applicable.
