Granny flats or ADU’s are the new trend in 2021. We have seen our amount of leads or homeowners nearly triple from 2019 to present times. Local San Diegans are aware of the shortage of housing that just does not seem to let up. The dilemma of limited supply also is creating a near untouchable real estate market for the average middle class person who does not already own. Many realtors and housing experts also attribute the recent pandemic as a source of supply issues. Homeowners are staying put, working from home and have no plans of leaving if they already are invested with a mortgage. With the surge of real estate prices and supply so low, Granny flats are an obvious answer to create more wealth, space or just simply housing solutions by using your existing property. So, what are the stipulations and qualifications to build an ADU on your San Diego property? Let’s walk through some of the common questions we receive.
California has really made it much easier to build granny flats with Assembly Bill No. 68 but here are some basic granny flat design restrictions/considerations for San Diego in 2021.
See the example table below directly from the San Diego county website.
|Square Footage of Existing single-family residence (SFD)||Maximum Allowed Square Footage for Detached ADU||Maximum Allowed Square Footage for Attached ADU (up to 50% of SFD)|
|1,450 sq. ft.||1,200 sq. ft.||725 sq. ft.|
|1,800 sq. ft.||1,200 sq. ft.||900 sq. ft.|
|2,000 sq. ft.||1,200 sq. ft.||1000 sq. ft.|
|3,000 sq. ft.||1,200 sq. ft.||1,200 sq. ft.|
|4,500 sq. ft.||1,200 sq. ft.||1,200 sq. ft.|

Now getting into more design specifics a general rule of thumb, for granny flat designs in San Diego is that you want to consider the transition of existing architecture to your new granny flat building. In other words, if you currently have Spanish Colonial architecture you would want to carry the same look and feel vs doing a modern look or craftsman style. You would want to use matching exterior to synchronize everything.
If you are building a stand alone ADU you should absolutely use the outdoor space or backyard to your advantage. San Diego weather is nice all year, so look at the outdoor space as potential extra living room space. An extended deck, fire pit or open doors that let the sun in are great design ideas to capture more of the paradise weather and feeling less confined to a small living footprint.
Construction costs in general should NEVER be templated, generic pricing. There are too many specifics involved with your property, your design specifications and even down to the amenities and products you choose to go with. For example, if you opt for ceramic roofing tiles vs asphalt shingles there is going to be a price difference. Ceramic roofing lasts about 3x as long as asphalt shingles and also the cost to install and rough product pricing is much higher.
All things considered to give a good price range for 2021, homeowners should consider (with caution, see above) to pay anywhere from $275-$500 per sq. foot for your granny flats.
As with any construction in San Diego you will be required to obtain a Building Permit to ensure that the new house meets all the zoning, building, health & safety codes. Depending on whether or not you live in an incorporated or unincorporated area of San Diego that will dictate the process. The simplified, standard council approval for a granny flat is:
Above is a simplified version as there are miscellaneous fees and processes depending on the county you are located. Please note, due to the pandemic the county has been very delayed in their processing at this time in August 2021.
