But just like checking the tide before surfing at La Jolla, your ADU project needs careful planning to avoid unexpected setbacks. Discover our top six cost-saving strategies to make your ADU construction in San Diego not only efficient but also economical

1. Strategic Planning and Design

Before you lay the first brick or choose paint colors, the most crucial step is to have a rock-solid plan. Think of it as your roadmap through the construction jungle. In San Diego, where the sun shines bright and the ocean breeze is never far away, designing with the local climate in mind isn’t just smart; it’s essential.

Opt for designs that maximize natural light and ventilation, reducing your future energy bills. Remember, San Diego’s unique architectural vibe—ranging from Spanish to Modernist—should influence your ADU’s design, ensuring it enhances your property’s appeal.

Don’t forget to partner with a designer or architect who’s well-versed in San Diego’s zoning laws. Their expertise can streamline the approval process, saving you time and money. Plus, a design that avoids future alterations (think long-term!) can save you a bundle down the line.

2. Efficient USE OF SPACE

In San Diego, where the outdoor lifestyle is part of the city’s charm, designing your ADU to seamlessly blend indoor and outdoor living can significantly enhance its appeal and functionality. Opt for large windows or sliding doors that open up to outdoor spaces, effectively expanding your living area without the cost of additional square footage. Inside, consider space-saving solutions like Murphy beds, built-in cabinets, and multi-functional furniture that can transform a living area into a guest room in a snap.

Pro Tip: Use outdoor elements like patios or decks to increase your ADU’s functional space without the high costs of building larger indoor areas.

3. Energy Efficiency and Sustainability

San Diego’s sunny climate is not just great for the beach but also for harnessing solar energy. Investing in solar panels can reduce your ADU’s energy bills significantly. Additionally, consider energy-efficient appliances, LED lighting, and water-saving fixtures to cut down on utility costs. Proper insulation and the use of energy-efficient windows can also help maintain your ADU’s temperature, reducing the need for heating and cooling.

Pro Tip: Check out local incentives for installing solar panels and other energy-efficient upgrades in your ADU.


Choosing the right materials is like selecting the perfect ingredients for your favorite taco—it’s all about balance. In San Diego, where the climate can vary from the coast to inland, select materials that suit your location. Coastal properties might need materials resistant to salt air, while inland homes can focus on heat resistance.

Consider local materials to cut down on shipping costs and support San Diego’s economy. And remember, the right materials can reduce maintenance costs and boost your ADU’s energy efficiency.

Pro Tip: Keep an eye out for home shows or industry expos in San Diego. They’re great venues to snag deals on materials and get fresh ideas.

5. PhASED CONStruction APProaCH

Building your ADU in phases can offer financial flexibility and allow you to adjust your budget as the project progresses. Start with the essentials and then add on or upgrade as your budget allows. This approach can also help you deal with any unforeseen expenses without derailing the entire project.

Pro Tip: Carefully plan each phase with your contractor, ensuring that the work is done in a logical sequence to avoid redoing any completed work.

6. Choosing the Right Contractor

Your contractor is the captain of your ADU ship. Choosing the right one is like picking the best surfboard for the wave—it can make all the difference. In San Diego, you want a contractor who’s not just experienced but also knowledgeable about local regulations and has a good rapport with the city’s building department.

Don’t just settle for the first contractor you meet. Get multiple quotes, check their portfolios, and, most importantly, ensure they have a solid track record with ADUs in your specific San Diego neighborhood.

Pro Tip: Use online platforms to read reviews and check ratings of contractors specializing in ADUs in San Diego. Local knowledge is key!
