I am writing to highly recommend Moe of NJ Design and Build for his exceptional work as a contractor. Moe and his team recently completed the construction of an Accessory Dwelling Unit (ADU) in my backyard for my father, and the entire experience was nothing short of excellent. From the outset, Moe impressed us with his professionalism, transparency, and deep knowledge of the construction process. He took the time to thoroughly understand our needs and offered valuable design insights, and helped us navigate every step of construction with patience and care. The quality of workmanship delivered by NJ Design and Build was outstanding. The ADU was built with great attention to detail, on time, and within the agreed budget. Moe maintained consistent communication throughout the project and was always accessible when needed, ensuring we were informed and comfortable with all decisions being made. His crew was respectful and skilled, a true reflection of his leadership and standards. What stood out most was Moe’s genuine care for our family's needs. He understood that this ADU was not just another project, but a home for my father, and he treated it with the same consideration and integrity he would for his own family. I would not hesitate to work with Moe again and wholeheartedly recommend NJ Design and Build to anyone in need of a reliable, skilled, and trustworthy contractor. They truly deliver on their promise of quality and client satisfaction. Thank you Moe and team for a job well done. Sincerely, Christina Johnson Poway, CAPosted on Google![]()

We hired Najmna to build an ADU in our backyard and the experience exceeded expectations. They handled the permits, construction, and inspections seamlessly. What I appreciated most was their transparency—no hidden costs, just honest work. Our new ADU came out beautiful and added real value to our property.Posted on Google![]()

Sorry for the long review but NJ design and build need to be recognized All their employees are very kind and respectful let me start with Sajed ( very kind and reliable. She took care of all city permits with hassle free on my end. She is very knowledgeable and knows how to take care of all permits).Moe has a very kind and honest heart ( it’s very rare to find a contractor with this beautiful quality) 1. NJ Design and Build handled my detached ADU from design to permits. They made the process smooth and kept me updated the whole time. No surprises, just solid work. 2. They designed and permitted my ADU and knew exactly how to deal with the city. Everything stayed on track 3. Professional and easy to work with. They explained everything clearly, took care of the permits, and the finished ADU turned out great. 4. I didn’t know where to start with an ADU, but they handled it all plans, permits, and construction. Made the whole process much less stressful. 5. Great experience. They managed the permit headaches for me and kept the project movingPosted on Google![]()

Engineering and permitting process was good and fairly seemless. Price was competitive and initial demolition was good as expected. Tile layer is skilled and professional. Some of finish carpenters, etc. we’re lacking experience and quality control as appeared to be a shortage ok skilled labor. Moe the GM was very responsive, flexible, and pleasant to work with.Posted on Google![]()

Did a great job fixing what another contractor really messed up. They are very professional and experts in what they do.
We study your lot, setbacks and views, then turn your goals into floor plans, a transparent budget and a realistic schedule.
We prepare drawings and engineering, pull every permit and handle plan check, HOA and coastal review where needed. Custom-home permits in San Diego often take 4–9 months.
Our crews build from foundation to finishes with weekly schedule updates. A ground-up custom home typically takes 12–18 months of construction.
Final inspections, a detailed walk-through and handover — backed by our workmanship warranty and one phone number if anything needs attention.
Straight answers to the questions San Diego families ask most before they build a custom home.
Plan on roughly 12–18 months of construction for a ground-up custom home, plus time upfront for design and permitting. Custom-home permits in San Diego often take 4–9 months because of plan-check rounds and, near the coast, Coastal Commission review. We give you a written schedule before construction starts and update it weekly, so you always know what comes next.
Cost depends on the size of the home, your lot, the design and the finishes you choose, so we don’t quote a one-size-fits-all number. After your free consultation we give you a transparent budget tied to your floor plan. Because design and pricing stay with one design-build team, the budget is checked at every design decision instead of after the plans are finished.
Yes. As your licensed general contractor we prepare the drawings, pull every permit and schedule every inspection. Many San Diego neighborhoods — Rancho Santa Fe, La Jolla, Coronado, Solana Beach, Del Mar — carry HOA design review, and properties west of I-5 often need a Coastal Development Permit. Our in-house design team prepares the HOA package and works through Coastal Commission requirements for you.
It helps. Slope, setbacks, utilities, HOA rules and the Coastal Zone all affect what you can build and what it will cost. Bring the lot details to your free consultation and we’ll flag the issues that matter before you commit.
Yes. We work with vetted lenders who specialize in construction financing, including construction-to-permanent and single-close construction loans. We are not a lender, so our advice is unbiased — we help you choose the structure that fits your project and costs you the least.
Every NJ Design & Build home is backed by California’s 10-year statutory warranty on latent structural defects, our 1-year comprehensive workmanship warranty, and the full manufacturer warranties on appliances, roofing, windows and finishes. If something isn’t right after handover, one phone call brings our team back out.
Yes — free, with no obligation and no high-pressure pitch. Meet us in person or virtually. We listen to your goals, review your lot or plans, and talk through realistic budgets and timelines so you leave knowing what’s possible.
Tell us about your lot, your timeline, and the home you’re picturing. We’ll respond within one business day with clear next steps and a no-pressure conversation.
