Re-Roofing an Existing Home


  • If your project meets the following criteria, you will be able to submit it through the Automated Online Permit System:
    • All new roofing material is Approved Class A Rating
    • The additional weight on the roof (if any) may be no more than four (4) psf. However, you may deduct existing material from the weight requirement.
  • If your project does not meet the above criteria, you must submit the application materials electronically through the IrvineReady Online Permit Submittal Portal
  • Your Homeowners Association may have its own approval process. Review your HOA policies and procedures before proceeding with your design plans

Zoning Guidance

  • If you are changing the height of the roof, verify that it will comply with the maximum building height in your zoning district. In many single-family neighborhoods, the maximum height is 35 feet, however, this will depend on the specific zoning for your property

To find the zoning for your property, you may refer to the Zoning Map or to the Online Parcel Search. You may also contact the Planning Counter at 949-724-6308.  

Requirements for each zoning district are outlined in Chapter 3-37 of the Zoning Ordinance. For your convenience, zoning requirements for two of the most common residential zoning districts are linked below.

Zoning requirements for the 2.2 Low Density Residential Zone

Zoning requirements for the 2.3 Medium Density Residential Zone

  • In most cases, roof eaves may intrude a maximum three (3) feet into a required front, side, or rear setback area
  • For properties with a zero-lot line (most commonly in Turtle Rock and University Park):
    • In situations where the easement is less than three feet in width, eaves are prohibited
    • In situations where the easement is three feet in width, the entire width of the eave, including any rain gutter, shall be no greater than one foot, measured from the face of the exterior wall
    • In situations where the easement is at least five feet in width, the entire width of the eave, including any rain gutter, shall be no greater than three feet, measured from the face of the exterior wall
    • In situations where eaves are permitted and the slope of the roofline causes water to drain toward the easement, rain gutters are required to ensure water does not flow onto the easement
    • In all instances the face of the eave, including any rain gutter, shall be set back a minimum of two feet from any property line, consistent with Section 503.2.1 and table 5-A of the Uniform Building Code
