There isn’t a definitive answer, as every city and county has their own regulations surrounding the size of an ADU. However, in general, an ADU is typically smaller than the main home on the property. The maximum size for an ADU is often capped at around 1,000 square feet.
If you’re interested in building an ADU that is larger than the size limit in your area, you may need to obtain a variance from your local planning department. variances are typically only granted for special circumstances, such as accommodating a disability.
If you’re simply looking for additional living space, you may want to consider building a second dwelling unit on your property instead of an ADU. Second dwelling units are typically allowed to be larger than ADUs and don’t require a variance. However, they come with their own set of regulations that you’ll need to follow.
In general, it’s best to check with your local planning department to see what size restrictions exist for ADUs in your area. They can provide you with the most accurate and up-to-date information.
Consider the space you have on your property to construct an ADU. While the reduced setback requirements may give you more room to plan and build your ADUs, because of some of the smaller lots that are historically known, space might still be a constraint when designing your ADU.
For example, if you have a two-car garage, you may be able to convert it into an ADU. Or, if you have a large backyard, you could build a detached ADU. There are many possibilities when it comes to designing an ADU that will work for your property.
It’s important to note that even if your city or county doesn’t have explicit size restrictions for ADUs, there may still be minimum square footage requirements. For example, some localities require that an ADU be at least 400 square feet in order to be considered habitable space. Others have no minimum square footage requirement at all.
Again, it’s best to check with your local planning department to find out what the specific requirements are in your area.
A small unit is often the best option even if you’re able to build a larger one. They tend to be less expensive and time-consuming to construct, and they have a higher turnover rate. This means that you’ll likely be able to rent it out more often, which can help offset the cost of construction.
Furthermore, tiny apartments are more popular among renters. Many individuals are searching for inexpensive, compact living spaces near to city centers. If you can offer this sort of housing, you’ll most likely be able to attract tenants.
You usually want to construct your ADU at the smallest size possible. This will help control construction costs and make it more likely that you’ll be able to find tenants. Of course, you ought to weigh this with any minimum-size legislation in your area. But in general, smaller units are better.
