The Gold Standard For ADU Construction In San Diego
Choosing Nova Remodeling for your ADU construction means partnering with a team that treats your backyard project like a custom home build. In San Diego, an ADU is one of the smartest investments you can make, but it involves complex engineering and strict city regulations. Unlike simple room addition contractors, we specialize in standalone dwellings. We understand the nuances of separate metering, soundproofing, and efficient small-space design. Whether you are building for family or for rental income, we deliver a high-quality, fully permitted unit that increases your property value and provides a comfortable living space for decades.
Why we are the preferred choice
Navigating City Permits
We handle the red tape. ADU regulations in San Diego are complex. Our team manages the entire permitting process, ensuring your project meets all zoning laws, setbacks, and building codes.
Custom Design Build
We design for you. Whether you need a studio for rental income or a two-bedroom home for aging parents, we create custom floor plans that maximize your lot's potential and style.
Utility Connection Experts
We connect it safely. Building an ADU requires precise trenching and connection to your main sewer, water, and electrical lines. We handle these critical infrastructure upgrades safely and efficiently.
Privacy Focused Layouts
We respect boundaries. We design ADUs that maintain privacy for both the main house and the new unit, using smart window placement and landscaping to create separate, comfortable living environments.
Seamless ADU Building Steps
1
Feasibility And Design
We start with analysis. We visit your property to check setbacks and utility access. Then, our architects create a custom design that fits your budget and meets San Diego’s specific ADU requirements.
2
Permitting And Approval
We handle the paperwork. We submit your detailed architectural plans to the city building department and manage all corrections and approvals so you don't have to deal with the bureaucracy.
3
Foundation And Framing
We build the shell. Once permitted, we pour the concrete foundation and frame the structure. This is when your new granny flat takes shape, defining the rooms and overall footprint.
4
Interior Final Finishes
We complete the home. We install the kitchen, bathroom, flooring, and fixtures. We ensure every detail is perfect, transforming the construction site into a fully move-in ready home.

Frequently Asked Questions
How much does it cost to build an ADU in San Diego?
The cost of an ADU varies significantly based on size, type (attached vs. detached), and finishes. A simple garage conversion will be less expensive than building a brand-new detached structure from the ground up. Generally, costs include architectural plans, city permits, site preparation, utility connections, and construction. During our free consultation, we provide a detailed estimate based on your specific lot conditions and design goals.
How long does the ADU construction process take?
Building an ADU is a significant construction project. The timeline typically ranges from three to six months for construction, but the permitting phase can add several months prior to breaking ground. San Diego has streamlined some processes, but approval times vary. Once construction begins, we work efficiently through foundation, framing, and finishing to get you the keys as soon as possible.
Can I build an ADU on my property?
In most cases, yes. California state laws and San Diego local ordinances have made it much easier for homeowners to build ADUs. Generally, if you have a single-family home or multi-family property, you are eligible. However, setbacks, power lines, and easements can affect placement. We perform a feasibility study to confirm exactly where and what you can build on your specific lot.
What is the difference between an ADU and a JADU?
An ADU (Accessory Dwelling Unit) is a complete independent living unit with a full kitchen, bathroom, and entrance. It can be up to 1,200 sq ft. A JADU (Junior Accessory Dwelling Unit) is smaller, usually under 500 sq ft, and must be contained within the existing walls of the main house (like a spare bedroom conversion). JADUs may share a bathroom with the main house but must have a separate entrance and efficiency kitchen.
. Do I need separate utilities for my ADU?
It depends on the type of ADU. For detached ADUs, you may choose to install separate electric and gas meters, which is highly recommended if you plan to rent the unit out, as it allows the tenant to pay their own bills. Water is often shared but can be sub-metered. We help you decide the best setup for your specific usage plans.
Can I rent out my ADU?
es, renting out an ADU is one of the primary reasons homeowners build them. In San Diego, you can rent your ADU for long-term tenancy (usually 30 days or more). Short-term rental rules (like Airbnb) are stricter and subject to specific city licenses and caps. We recommend checking the latest local ordinances regarding short-term rentals if that is your goal.
