What is the zoning and the setbacks of my house?
The Planning Division maintains a map that shows zoning for every parcel in the City. The map can be viewed in the Planning Division lobby, or anyone can call the planning department to speak with a planner regarding specific zoning, setback, and related questions. For zoning information call (925) 779-7035
A six-foot tall fence is allowed on property lines at the rear and sides of most properties. All fences in the front setback must be 3 feet or less AND NOT IN THE CITY RIGHT OF WAY. Any new fence requires a building permit. Please call the Building Division (925) 779-7065 for their requirements.

Can I convert my garage into an extra room?
Garage conversions are generally not allowed. All single family homes must have a 2 car garage with interior dimensions of 400 square feet. In some cases a third car garage may be converted. See Section 9-51703.1 of the Municipal Code for more information.
Can I split my large lot into two parcels and sell the new parcel?
A lot split is known as a “minor subdivision”; a minor subdivision creates a maximum of four lots and requires review at a public hearing conducted by the Planning Commission. If a resident owns property that is more than twice the size of the minimum lot area required by the applicable zoning, a minor subdivision may be possible. However, all new lots must meet minimum width and depth requirements. For example, property in the R-6 zoning district requires 6,000 square feet minimum lot area and 60 feet minimum lot width. Such lot area requirements must be met without including any portion of the private street/driveway providing access to any of the rear (flag) lots.
What is required for my home business?

Can I have daycare at my home?
A small family daycare (6 or less children) is considered a residential use of property and no business license or permit is required.
A large family daycare (7 or more children) may be allowed in single-family residences located on residentially zoned lots. An Administrative Use Permit from the Zoning Administrator is required. Click here for an application.
Legal Non-Conforming Uses
Definition: A legal non-conforming use is a use or structure which was legally established according to the applicable zoning and building laws of the time, but which does not meet current zoning and building regulations. A use or structure can become legal non-conforming due to rezoning, annexation, or revisions to the Zoning Code.
Must a Legal Non-Conforming Use be abandoned or altered to meet Current Regulations?
No, as long as the use is continuously operated and it is not discontinued or abandoned for more than a six (6) month period. However, if a legal non-conforming use is discontinued for six (6) months or more, the use loses its legal non-conforming status.
Can an abandoned Legal Non-Conforming Use be reinstated?
Possibly. A legal non-conforming use which has been discontinued for more than six (6) months may be reinstated with a Use Permit if it is found that the conversion to a conforming use would create undue hardship under the particular circumstances.
If a Legal Non-Conforming Structure is destroyed more than 50% of the replacement value by fire or other natural disaster can the use be re-established?
No. The structure may not be restored except in full conformity with the regulations for the district in which it is located, and the nonconforming use shall not be resumed.
If a Legal Non-Conforming Structure is damaged less than 50% of the replacement value by fire or other natural disaster can the use be re-established?
Yes. The building may be restored in its entirety if the new building does not:
Is there a Time Limit for Restoration of Legal Non-Conforming Use for Fire Damage or Natural Disaster?
Yes. The owner has six (6) months from the date of the destruction to apply for a building permit, and six (6) months from the date of issuance of a building permit to begin construction. If these permits are not secured within the time limit specified, the use shall be considered discontinued and abandoned.
Expansion of a Legal Non-Conforming Use
A legal non-conforming use may be expanded through the issuance of a Use Permit.
Adding Non-Conforming Uses to a existing Legal Non-Conforming Use
No structure partially occupied by a non-conforming use shall be moved, altered, or enlarged in such a way as to permit the enlargement of the space occupied by the nonconforming use.
