How does the code compliance permit process work?
Once it has been verified that there are no inspection records available for the work in question, the code compliance process can be initiated by the applicant. The process consists of:

1. Following the instructions in this handout.

2. Securing the required outside inspections, plans, and letters.

3. Submitting the required documents with a completed permit application to the Building Inspection Division.

4. Building division review, approval and permit issuance.

5. Scheduling of inspection by applicant.

6. Job card final; upon completing required field inspections the job card is signed off and the City's records are updated showing compliance.

How long does the code compliance permit issuance process take?
That depends on the scope of work being reviewed and legalized, also how quickly you can secure the necessary outside inspections, plans, and letters.

Once the required outside documentation has been submitted and approved, the Building Inspection Division can process your application in a few days.

How long is a building permit valid?
Permits and plan checks are valid for 180 days per the California Building Code.  Each time you call for a valid inspection, it automatically extends the life of your permit another 180 days.
Is there any type of work that does not require permits and inspection?
Yes, but to avoid any misunderstanding or confusion, the Building Inspection Division recommends that you contact a City inspector to discuss your specific situation. We are located at 500 Castro Street on the first floor in City Hall and can be reached at (650) 903-6313. Our counter hours are Monday—Friday from 8:00 am—4:00 pm. Our phone hours are 8:00 am—5:00 pm daily.  You can also check our Work Exempt From Permit section of the Building Division website.
What do I do about an expired permit?
You will need to contact the Building Division at (650) 903-6313.  Permits are valid for 180 days.  If you happen to let your permit lapse you can apply for a new permit to be issued.  The new permit description will state that it has been issued to final out the expired permit. You may have to provide new plans for this request as all of the original plans have been stamp EXPIRED and digitally imaged as permanent documentation for that site.

Permit fees for a lapse in excess of 180 days will be equal to half of the original fees paid. 

Permit fees for a lapse in excess of 360 days will be equal to original fees paid.
What do I do about work completed without a building permit?
There is a Code Compliance Process for that exact situation. 

If the work completed has added square footage to a building you would need to contact the Planning Division at (650) 903-6306.  Planning will determine whether or not the addition can legally remain.

Please look at our process on our web site Code Compliance Process and then contact the Building Division at (650) 903-6313 for any questions that you may have.
