We recently completed a conversion of a nearly 100 year old duplex back to it’s original single family home while also adding a two story addition for a master suite, master bath and nursery for a baby who arrived during the remodel.
This is a summary of the permitting requirements in San Rafael. An unusually fast office for any city, let alone Marin County!
We guarantee your project will be different! This is a great starting point if you are researching. Most people have never heard of all these permit requirements.
Here are our findings:
