Getting an ADU permitted is one milestone. Getting it built is another. 🏠

We followed detached new-construction ADUs in the City of San Diego from submission all the way through final inspection to see how quickly they became completed homes.

The gap between citywide and SnapADU projects grows significantly over time:
🏠 18 months: 13% citywide vs. 52% SnapADU
🏠 2 years: 24% citywide vs. 69% SnapADU
🏠 3 years: 43% citywide vs. 90% SnapADU

Why does completion matter? Applications tell us about demand and permits tell us about approvals, but final inspections tell us how many projects actually became finished housing.
For homeowners, it’s also an important reminder that the goal isn’t simply getting a permit. A successful ADU project requires feasibility, design, permitting, budgeting, and construction to stay aligned from start to finish.

Coming soon to La Mesa! This 560 sqft ADU is getting ready for construction, and it's all about keeping family close! 💚

The homeowners are planning to downsize into this 1BR/1BA ADU so they can age in place comfortably while staying close to their daughter and new grandbaby. The single-story layout will provide a smaller, more manageable home with room for their king-sized bed and easy everyday living.

The property sits on a slope, so the ADU will require a raised foundation to accommodate the changing elevation and create a level living space. The homeowners also chose one of our standard floor plans to save on design time and costs.

Although the property has a La Mesa address, it's actually located in unincorporated San Diego County, so permitting is handled by the County rather than the City of La Mesa.

We're excited to see this project take shape and help bring three generations of family closer together!

For this week's Feasibility Friday, we're featuring a custom ADU just under 600 sqft in San Diego's Bay Park neighborhood designed to give Mom a private home while doubling as a pool house for the whole family! 🏡 ☀️

The 1BR/1BA layout includes an enlarged kitchen and a living room with multifold doors that will open directly to the new pool, creating a flexible space for everyday living and poolside entertaining.

Building an ADU near a pool takes some extra planning! We generally recommend 6–10 feet of separation to reduce the risk of damage during foundation excavation. Proper drainage is also important to keep water away from the ADU.

Our team evaluates pool placement, grading, and foundation requirements during feasibility to identify challenges early. We're also coordinating with the homeowner's landscape designer to make sure the ADU, pool, & outdoor spaces flow well together.

Thinking about building a poolside ADU? Let's explore what's possible! ✨

How quickly do ADU projects actually get permitted in San Diego? ⏱️

We followed detached new-construction ADUs from the date they were submitted to see how many reached a permit over time, then compared the citywide results with identifiable SnapADU projects.

At 12 months after submission:
📋 43% of projects citywide had received a permit
✅ 92% of SnapADU projects had received a permit

By 36 months, 74% of projects citywide had been permitted, compared with 100% of SnapADU projects.

Getting through permitting efficiently starts well before plans are submitted. Understanding feasibility, utilities, site conditions, and jurisdiction requirements upfront can help reduce avoidable redesigns and corrections later in the process.

This two-story ADU on Collier Avenue in San Diego is getting close to the finish line! 🏡

The 1,037 sqft 2 bedroom, 2 bathroom home is designed for the property owner to downsize into, allowing them to enjoy a lower maintenance living space while creating the opportunity to rent out the main house.

As construction progresses, the ADU is starting to closely resemble the original renderings. Key design features are taking shape, including the upper-level deck and clerestory windows. Swipe to see the comparison! ➡️

Just completed in San Diego! 🏡 This 749 sqft, 2 bedroom, 2 bathroom ADU was built behind an existing home to generate rental income. The homeowner selected one of our standard plans to save time and design costs while keeping the project just under 750 sqft to avoid additional impact fees.

The L-shaped layout features:
🏠 Open-concept living room and kitchen
🛏️ Two bedrooms, each with an ensuite bathroom
🧺 In-unit washer and dryer
🌿 Private patio tucked within the “L”

Located in a High Fire Hazard Severity Zone, the ADU required fire-rated construction. Site preparation included removing several trees and the home’s existing rear patio cover. The homeowner finished the space with a small lawn, mulch, and landscaping for the new tenants.

A custom coastal ADU is coming to Encinitas! 🌊🏡

Located in the Channel Island HOA, this nearly 500 sqft ADU will provide a private 1 bedroom, 1 bathroom home for the homeowners’ parents. The customized design includes multifold doors on two sides of the living room, creating an open concept space with a strong indoor-outdoor connection.

Building an ADU in an HOA requires additional planning. While an HOA cannot prohibit an ADU, the project may still need to follow reasonable architectural standards related to exterior materials, colors, roofing, and overall appearance. Addressing these requirements early helps keep the design and approval process moving forward.

Stay tuned as we share updates on this Encinitas project!

How many submitted ADUs actually become finished homes? 🏠

We followed 1,535 detached new-construction ADU projects submitted to the City of San Diego that had at least three years of history. Within three years of submission:
✅ 74% received a permit
🏠 Just 43% reached final inspection and became completed ADUs

That means getting an ADU submitted, or even permitted, doesn’t necessarily mean it will ultimately get built. This is why we wanted to look beyond the usual application and permit totals. By following individual projects from submission through final inspection, we can get a clearer picture of how many proposed ADUs actually turn into completed housing.

It’s Feasibility Friday in Oceanside! 🏡🌊 & today, we’re featuring a stacked ADU project that will add two new rental units behind an existing duplex.

The homeowner plans to generate additional rental income with a two-story structure. Each floor will contain an identical 706 sqft, 2 bedroom, 2 bathroom ADU. The kitchen and living area sit at the center of each floor plan, with a bedroom and ensuite bathroom on either side.

California’s multifamily ADU laws allow qualifying properties to add detached ADUs based on the number of existing units, up to eight. Because this property has an existing duplex, the homeowner can build two detached ADUs.

Building vertically makes efficient use of the available space, but two-story ADUs in Oceanside must follow the setbacks established by the property’s zoning rather than the reduced 4' side and rear setbacks commonly available for ADUs.

During feasibility, our team evaluates zoning, setbacks, existing structures, access, utilities, and other site conditions to determine where the ADUs can fit and identify potential hurdles before design begins.
