Starting 2026 Strong: How to Plan Your ADU the Right Way This Year
Introduction
The beginning of a new year is when smart homeowners take stock, set goals, and make strategic decisions about their property. In San Diego, where housing demand remains strong and ADU regulations continue to evolve, 2026 is shaping up to be a pivotal year for accessory dwelling units.
If building an ADU has been on your radar—even loosely—January is the ideal time to move from “thinking about it” to planning it the right way.
At ADU PALS, we’ve seen firsthand that the most successful ADU projects aren’t rushed. They’re planned early, thoughtfully, and with a clear purpose in mind.
1. Start With the “Why” Behind Your ADU
Before talking design, budget, or permits, the most important question is simple:
What do you want your ADU to do for you?
Common goals we see from San Diego homeowners include:
Generating long-term rental income
Creating housing for aging parents or adult children
Increasing overall property value
Gaining flexibility for future life changes
Adding a dedicated home office or studio
Your “why” drives every downstream decision—from layout and size to finishes and site placement.
2. Understand What Your Property Can Actually Support
Not every lot is created equal, and zoning rules alone don’t tell the full story.
Early in the planning process, it’s critical to evaluate:
Lot size and usable buildable area
Access, slope, and existing utilities
Fire zone and setback requirements
Parking and driveway constraints
Sewer and water capacity
This feasibility step saves homeowners thousands of dollars by avoiding designs that look great on paper but don’t work in reality.
3. Plan Around the Permitting Timeline
Even with streamlined ADU rules, permitting in San Diego is not instant.
Typical timelines include:
Design & feasibility: 4–6 weeks
Permit review: 3–5 months (sometimes longer in fire zones or complex lots)
Construction: 5–7 months depending on scope
Starting your planning in January positions you for:
Spring or early summer construction starts
Better contractor availability
Fewer end-of-year bottlenecks at the city
Waiting until mid-year often means delays—and higher stress.
4. Build a Realistic Budget (Not Just a Construction Number)
One of the biggest mistakes homeowners make is focusing only on build cost.
A complete ADU budget should include:
Design and engineering
Permits and city fees
Utility connections or upgrades
Construction and finishes
Contingency reserves
In 2026, custom-built ADUs in San Diego typically range from $200,000 to $400,000+, depending on size, site conditions, and finishes. Planning early allows you to align scope with financing and long-term ROI expectations.
5. Explore Financing Options Early
January and February are ideal months to line up financing before lender pipelines fill up later in the year.
Common ADU funding strategies include:
HELOCs or home equity loans
Cash-out refinances
Construction or renovation loans
Private or blended financing strategies
Securing financing early prevents project delays and gives you leverage when making design decisions.
6. Decide Between Pre-Approved Plans and Custom Design
San Diego now offers pre-approved ADU plans, which can shorten review times for certain properties. However, they’re not always the best fit.
Pre-approved plans work best when:
The lot is flat and unconstrained
A standard layout meets your goals
Speed is the top priority
Custom design is often the better choice when:
You want to maximize rental income or resale value
The site has slope, access, or fire constraints
You’re designing for family or long-term flexibility
The right choice depends on your goals—not just speed.
7. Choose Your ADU Team Carefully
An ADU is not just a construction project—it’s a regulatory and financial one.
The right ADU partner should:
Understand San Diego zoning and permitting deeply
Design with ROI, livability, and compliance in mind
Be transparent about costs and timelines
Guide you from concept through completion
Early conversations matter. The builder you choose in January shapes your entire experience.
Conclusion: The Best ADU Projects Start Early
If 2026 is the year you want to add income, flexibility, or long-term value to your property, planning now is the smartest move you can make.
January isn’t about rushing—it’s about setting the foundation so everything that follows is smoother, faster, and more predictable.
