Modern One Bedroom ADU for Family in La Mesa
Anaheim Drive, Casa de Oro-Mount Helix, CA 91941
Homeowner Story: Bring aging family closer
This 663 square foot, 1 bedroom, 1 bathroom ADU will provide a comfortable home for the homeowners’ parents, allowing them to move closer to family and help with their new grandchildren. They’ve opted to start with one of our standard plans and make thoughtful modifications such as relocating windows and adding a sliding glass door to better suit the site and take advantage of the property’s views. Situated on a large lot in La Mesa, the ADU has been carefully positioned to maximize the surrounding scenery while creating a private & functional space. We look forward to bringing this multigenerational project to life!

The La Mesa ADU Guide
We’ve worked on ADU projects throughout La Mesa and have found the City’s permitting process to be relatively straightforward compared to many other jurisdictions in San Diego County. La Mesa accepts digital permit submissions, offers clear permit tracking, and has a reputation for being responsive during the review process.
One of the more unique advantages for homeowners is the City’s ADU fee waiver program. To encourage ADU development, La Mesa waives the first $2,000 of permitting fees associated with ADU projects. In addition, many ADU projects are exempt from certain impact fees, helping reduce upfront development costs.
La Mesa ADU Permitting
Most ADU permits in La Mesa are approved within approximately 5 to 6 months after submission, although timelines vary depending on project complexity and city workload. Permit costs generally range from approximately $8-10/sqft, though the City’s ADU fee waiver program can help offset a portion of these expenses.
La Mesa generally requires soils reports for ADU projects at the time of permit submittal. However, City staff has indicated that very small one-story projects in favorable soil conditions may occasionally qualify for a waiver on a case-by-case basis.
