Solid ADU is active in Northridge and the immediate area, including Reseda, Granada Hills, Chatsworth and North Hills. We can guide your ADU plans & permits too, from first advice through the final LADBS inspection, with the build done by a licensed contractor from our network.
Northridge grew up around orange groves and then around Cal State Northridge, and today the university shapes the local rental market: students, faculty and staff are all looking for smaller, well-located places to live. The housing stock is dominated by 1950s and 1960s ranch homes on wide suburban lots, most with two-car garages and plenty of remaining yard. That makes Northridge one of the most practical places in the Valley for a garage conversion or a detached ADU built for steady rental income. A typical converted garage here becomes a bright studio or one-bedroom with its own entrance, kitchen and laundry. We handle the LADBS permit package and every inspection, and you get a fixed proposal up front so you know exactly what you are building and why. Think of 1950s and 1960s ranch homes, wide suburban lots with two-car garages, mid-century tract homes and single-story homes near CSUN: we tailor the approach to the type of home and the condition of your lot and existing structures.
Before a single wall goes up, every ADU in Los Angeles needs an approved set of plans and a building permit from LADBS, the Los Angeles Department of Building and Safety. That means architectural drawings, structural calculations, a Title 24 energy report and a plan check review by the city. For most homeowners, this paper phase is the most confusing part of the whole project. It is also where projects stall.

ADU Plans & Permits in Northridge: what is possible
Free feasibility check
We review your lot before you commit: zoning, lot size, existing structures, setbacks, utilities and access. You get a straight answer on what kind of ADU your property supports and what the path to a permit looks like.
Site measurement and as-built drawings
Your design team measures your property and existing structures and draws them up as they stand today. Accurate as-builts are the foundation of a clean plan set, especially for garage conversions where the existing structure carries the design.
ADU design and floor plan
A licensed architect designs the layout around how the unit will actually be used: rental, family member or home office. You review the floor plan and elevations and approve the design before anything goes to the city.
Permit-ready architectural drawings
The full plan set LADBS requires: site plan, floor plans, elevations, sections, construction details and code notes. Drawn to city standards so the plan checker can review it without guesswork.
Structural engineering and calculations
A licensed structural engineer calculates foundations, framing and seismic loads and produces the structural sheets and calculations LADBS requires. For garage conversions this covers new openings, infilled garage doors and any strengthening of the existing structure.
Title 24 energy calculations
Title 24 is California's building energy code. Your design team produces the required energy compliance report covering insulation, windows, heating, cooling and water heating, matched to the products the project will actually use.
LA ADU Standard Plan Program guidance
LADBS maintains a list of pre-approved ADU standard plans. Because the design itself is already reviewed, plan check focuses on site-specific items, which can save time. We advise honestly on whether a standard plan or a custom design fits your lot and goals better.
LADBS plan check submission
Your design team prepares and submits the complete application through the city's online system, including all required forms and clearances. We coordinate the package and check it for completeness, because a complete, well-organized submission is the single biggest factor in a fast review.
Plan check corrections handled
Almost every application gets a corrections list from the plan checker. Your design team responds to each comment, revises the drawings and resubmits until the set is approved. We track every round and translate the city's comments into plain English, so you always know where your application stands.
You can find the full overview on our ADU plans & permits page.
Why invest in ADU plans & permits?
Most homeowners who call us are not short on motivation. They are stuck on the process. Sound familiar?
- You do not know if your lot even qualifies for an ADU, and every website tells you something different.
- You want to convert your garage but have no idea what the city requires structurally or where to start.
- A draftsman or online plan service got you halfway, and now the application is stuck in plan check corrections nobody is answering.
- Contractors are happy to quote the construction, but nobody wants to own the drawings and the permit paperwork.
- You have heard about setbacks, height limits and parking rules and cannot tell which ones apply to your property.
- Your garage was partially converted years ago without permits, and you are worried that blocks you from doing it right now.

ADU Plans & Permits costs in Northridge
What ADU plans and permits cost depends heavily on the project. A garage conversion using the existing structure is a very different scope than a new two-story detached ADU on a sloped lot. That is why you will not find standard prices here: they would be wrong for your situation more often than right.
- New construction or a conversion of existing space, such as a garage
- The size of the unit and the complexity of the design
- One story or two, and whether the ADU sits above or attached to another structure
- How much structural engineering the project needs, including the condition of an existing garage
- Whether your lot is in a hillside area or another zone that requires extra reports or clearances
- Soils or geology reports, when the location of the lot requires them
- A custom design versus a pre-approved plan from the LA ADU Standard Plan Program
- The scope of the Title 24 energy report and whether solar requirements apply
