Residential Second Dwellings ("Granny Flats")
How to Obtain a Building Permit
Obtaining a Building Permit
"Granny Flat", "In-Laws Quarters" or any residence that is in addition to an existing residence on a parcel is a the Second Dwelling. General requirements are the same as the construction of a primary residence with only a few exceptions.
Maximum square footage of living space is dependent on zoning and lot size. A garage or storage space may be attached to the dwelling and not considered part of the maximum square footage of living space.
If a manufactured home is used as a second dwelling, please go to our
manufactured home page for additional requirements.
- Building Services permit application requires the following:
- Complete the three part
application and sign where applicable (signature must be verified by office personnel). If you are applying as owner-builder, you must be the owner of record and complete part four of the multi part application. If property ownership was recently changed a copy of the grant deed may be required at time of application.
- When other than the owner or licensed contractor is applying for the permit, the second half of part four of the form must be completed, giving authority to sign as the owner's agent.
- An owner or their agent must sign a
Deed Restriction Certificate declaring conformance with any applicable deed restrictions and/or CC&R's for subject property.
- If the property is within the architecturally controlled area of
El Dorado Hills Community Services District or
Cameron Park Community Services District, architectural approval of the plans from the district prior to permit issuance is a requirement. Failure to obtain approval may delay issuance of your permit.
- Check with your individual association for any restrictions that may affect your construction even though Building Services does not enforce these restrictions.
- Contractors acting as agent for the owner must have a current active
California state contractors license, worker's compensation coverage, and a
current El Dorado County Business License.
- When served by a public water/sewer district other than
El Dorado Irrigation District, you must submit proof of service from the district prior to permit issuance. When serviced by EID, they will review your project and approve electronically.
Georgetown Public Utility District will require the review of the second dwelling.
- When not served by public water/sewer, you must submit the perc test, septic design and well production report to the
Environmental Management. This may only be submitted with or after building permit application.
- If your parcel is located at or above the 4000 foot elevation, a bear resistant garbage enclosure will be required. Contact
Environmental Management for additional information.
- An Encroachment permit is needed if you are connecting your new driveway to a County-maintained road. See the county
Fire Safe Regulations for driveway information.
