Client Reviews
What Our Clients Say
Real reviews from LA homeowners we have helped with violations, ADUs, and construction projects.
"CCS has been a life saver. Our neighbors complained about our kitchen remodel and we got cited for remodeling with no permits. Our contractor said we didn't need one but obviously we did. Hayden and Pablo were great, patient, thorough and got us through the permit process and saved us from paying violation fees."
"Words simply can't express the level of appreciation we have for Danny at CCS Inc as they converted our unused garage space into an accessory dwelling unit. From design to financing and permitting to the project execution, every aspect of our project was well taken care of."
"The best part about this business was how easy they made the whole process. They broke down the steps for me in a way that made sense and kept me in the loop from day one. The craftsmanship on the cabinets and flooring is top notch. My garage looks nothing like it did before."
Common Questions
Frequently Asked Questions
Answers to the questions LA homeowners ask us most about building violations, ADUs, and permits.
When you receive an Order to Comply (OTC) from LADBS, the first step is to read it carefully to identify every item that requires a permit or correction, then contact the inspector listed on the order. As the current property owner, you are responsible for resolving the violation even if prior owners caused it. Acting quickly matters — delays can result in re-inspection fees, escalating late penalties, referral to the City Attorney's Office, and in serious cases, criminal prosecution. A licensed compliance specialist can assess the violations and map out the fastest, most cost-effective path to resolution.
Unpermitted work can often be legalized through a retroactive "as-built" permit, which requires hiring a designer to draft construction documents (site plan, floor plans, electrical plan, Title 24 energy report) and submitting them for plan check review at LADBS. If the work passes inspection and meets current code, a retroactive permit is issued — but if it does not meet code, you may be required to modify or demolish the work entirely. For unpermitted ADUs built before January 1, 2020, California's AB 2533 (effective 2025) provides an amnesty pathway with waived impact fees if the unit passes a health-and-safety inspection.
In 2025–2026, the cost to build a new detached ADU in Los Angeles typically ranges from $200,000 to $400,000+, while a garage-to-ADU conversion generally runs $95,000 to $225,000 depending on the scope of work. Construction costs average $300–$400 per square foot, and soft costs (architectural plans, engineering, permits) add another $15,000–$45,000 on top. Key factors that drive cost include ADU type, lot conditions, finish level, and state-mandated requirements such as solar panels and fire sprinklers.
The ADU permit timeline depends heavily on whether you use a pre-approved standard plan or a fully custom design. Under AB 1332 (effective January 1, 2025), all California cities must offer a pre-approved ADU plan program; permits using those plans can be issued in as little as 3–4 weeks. Custom designs require a full plan check, and while state law mandates a 60-day review, most custom projects take 4–6 months from design to approved permit. Total time from project start to move-in typically runs 9–18 months for a new detached ADU.
A Notice to Comply (also called an Order to Comply or OTC) is an official order from LADBS or the LA Housing Department notifying a property owner that their property violates local building or housing codes. It is legally serious — failing to respond by the deadline can trigger daily fines, re-inspection fees, and ultimately referral to the City Attorney for prosecution. There are strict appeal deadlines, so property owners should not wait to act. A qualified compliance consultant can respond to the order, pull the required permits, and coordinate inspections to get the case closed efficiently.
Yes, garage conversions are legal in Los Angeles on most residential-zoned properties (R1 through R4), and they are one of the most popular and cost-effective ways to add an ADU or Junior ADU (JADU) to a single-family lot. A building permit is required from LADBS, and the converted space must meet all applicable building, electrical, and plumbing codes. Importantly, replacement parking is not required if the property is within half a mile of public transit. Unpermitted garage conversions already in existence can potentially be legalized through the AB 2533 amnesty program if the unit was built before January 1, 2020.
