Attachment Copies Required with Plans

Provide 3 copies of soils reports
 
The 2010 CBC, section 1802.2 requires a soils report for all work that requires a foundation, with some exceptions. This requirement has significant financial implications as related to small residential additions. In researching this, I found neighboring jurisdictions that have policies that address this that make sense for us to consider. As a result, we will be using the following for our policy:
  • Any residential addition not exceeding 500 sq ft with an existing foundation that is serviceable will not need a soils report provided the same style foundation is used for the addition.
  • Any residential addition over 500 sq ft will need a written statement from the designer or owner that the existing foundation is not damaged or failing in any area. If the foundation statement is provided and the foundation is accepted then the same style foundation may be used without the need for a soils report.
  • All new residential foundations (new homes) will require a soils report for plan check.

Please note this policy only applies to residential construction.

Prior Steps Before Submission of Plans
  • Approval and wet stamp of plans by the City of Richmond Planning Dept: 510-620-6705
  • Approval and wet stamp of plans by the Sanitary District serving the property:
    • West County Waste Water District: 510-222-6700, or
    • Stege Sanitary: 510-524-4668, or
    • City of Richmond Waste Water District: 510-307-8091. (Projects within this district may be submitted prior to obtaining approval. Permit will not be issued until sewer district has stamped and approved.)

Step to Do During Plan Check / Approval Review Process
Payment of a School District Fee and Obtaining of a Receipt for Submission
The fee is based on square footage and is levied on all dwelling additions. The school district collects the fee and issues a receipt that must be submitted to the Building Department before permit issuance. Note: This fee shall not be paid until you have been contacted by a City of Richmond Permit Technician and have been informed to do so.
