5 Things to Know About Granny Flat Regulations in San Diego
Bigger is Better - San Diego expanded the maximum size of a granny flat from 700 sq.ft. to 50% of the primary residence’s size, or 1,200 sq.ft, whichever is less.
City-backed Resources - San Diego city officials are creating step-by-step manuals, along with a set of pre-approved granny flat designs, to help accelerate construction.
Encinitas Leading the Way - Homeowners in Encinitas can build granny flats up to 1,200 sq.ft. and are eligible to save around $3,500 in waived fees.
Vacation Rentals a No-Go - City regulations stipulate that lease agreements for granny flats must be no less than 30 days. This discourages homeowners from building a granny flat as a vacation rental.
Fees Range Significantly - Depending on where you live and the type of granny flat you’re looking to build (size, features, etc.), permitting fees and construction costs could range significantly. Check with your local city council before you get started.
