TL;DR Summary for Those in a Hurry:

Junior Accessory Dwelling Units (JADUs) are compact, self-contained living spaces of up to 500 sq ft created within an existing home — like a garage or unused room — to add rental or family-friendly space.
They must have a separate exterior entrance and a small kitchen (“efficiency kitchen”), and they can share a bathroom with the main house or have their own.
Because they use interior space and existing utilities, JADUs usually cost less and get through permitting faster than full ADUs.
Owners can use JADUs for long-term rental income, guest housing, or extended family living, often with lower construction impact.
Professional design and permitting help ensure compliance with space, access, and code requirements for a smooth build.

 Trustindex verifies that the original source of the review is Google. If you’re looking for an HVAC contractor you can actually trust, call Ernie at Upright Construction & HVAC. Ernie was incredibly generous with his time, patient with all of our questions, and kept his word throughout the entire project. He helped us choose the most efficient system for our home, clearly explained the pricing, handled the permits and paperwork, and Upright stuck to their quote with no surprises. His crew was professional, respectful, efficient, and treated our home with tremendous care. We hired Upright to remove our old HVAC system and install our new one, but after this experience, Ernie will be our first call for any future construction or contracting work. Honest, knowledgeable, dependable, and genuinely cares about his customers. I would recommend Upright Construction & HVAC to anyone. Thank you again, Ernie and team!

 Trustindex verifies that the original source of the review is Google. So thankful for Ernest and his team to come out on a whim. Answer questions, provide knowledge, and did not try to upsell or spill BS, just a straight shooter. He got me the best deal at the best price. I am thankful that there is still nice quality people in the world!

 Trustindex verifies that the original source of the review is Google. My AC broke on a Saturday night during a heat wave. Ernie fit me in that same night and fixed the problem. He was professional, pleasant, and reasonably priced. I'd recommend him and use him again.

 Trustindex verifies that the original source of the review is Google. If I could give Ernie 10 stars, I absolutely would!! I messaged him at 11pm on a Friday night after my A/C went out on me in this insane heat wave and he got back to me right away and then came out first thing the next morning on a Saturday. I genuinely thought I was going to perish in this heat until Monday but NOPE… by 9am, I was already up and running again and with air that was even colder than it was before it went out. As a single woman, I’m used to different contractors using that to underestimate me to upsell on things I don’t need but there was zero of that with Ernie. In fact, quite the opposite. Ernie worked to get just what needed fixing fixed and explained everything to me in a digestible way to help me get the most out of my A/C unit without having to come thousands of dollars out of pocket for a new unit. On top of that, he has the most genuine soul and is a family man so I felt safe and completely taken care of. His service is top notch and not the kind you get anymore these days. If you need any HVAC or construction work done, look no further. 10/10 recommend Ernie… he’s a gem!!

 Trustindex verifies that the original source of the review is Google. Ernie communicated often while en route to our house.  Once he got there, he assessed the situation and presented a reasonable solution that he was willing to do right now, even though it was getting late.  He didn’t mind at all since it was cooler and our issue would be fixed.  It was a wonderful experience!  Very up front and honest, which was much appreciated.

 Trustindex verifies that the original source of the review is Google. I called Ernie due to our A/C leaking. He came out right away and was very friendly and pleasant. The issue ended up being a minor repair (a clogged P Trap that needed to be replaced). The cost was $375, but he knocked off $25. He was personable and helpful, and I am grateful that he was able to come out so quickly. We would definitely call Ernie again.
