Additions we've built

Ardmore Ave, Oakland

Full home remodel & addition

24 weeks

This 2,355 sq ft home built in 1922 in Oakland was sold for $2.2 million while we were still remodeling the home. The home hadn't been remodeled or updated since it was originally built. So when the homeowners approached us with this project asking us to bring the home up to date and add a 500 sq ft addition in the basement, we knew we were in for a serious project.

To update the home with modern appliances we had to completely upgrade the homes electrical system. This process involved taking out the old drywall to be able to access and remove the old wiring all throughout the home. Once the old wires were removed, we replaced them with modern code compliant electrical panels, wiring, and GFCI outlets. With the electrical done, we began taking out the old wood floors to prepare them for new flooring. We used hardwood for the living rooms and bedrooms, and used tile in the kitchens and bathrooms. The roof was also completely replaced which hadn't been done since the home was built.

With the basics taken care of we moved on to build out the rooms in the home. The homeowner wanted to take advantage of the beautiful view from the home so we installed a generous set of windows throughout the home. You'll see that the home office was positioned to take advantage of the view. For the bottom floor, we built an additional bedroom, bathroom and a spacious laundry room with a door that opens up to the backyard. Back upstairs to the living room, we updated the living room fireplace, installed new recess lights, and elegant crown molding throughout the room. In the kitchen, we installed natural stone countertops with a custom recess for the bump out sink, custom cabinetry, counter to ceiling backsplash, and a new set of Fisher & Paykel appliances.

The kitchen's view opens up to the newly landscaped backyard and the newly built deck.

Bridge Rd, Walnut Creek

Home remodel & office addition

16 weeks

This home was built back when Walnut Creek was just a collection of walnut groves. The homeowners wanted to take this dated home and turn it into a spacious modern family space by extending the living room and converting the garage into a home office. From the outside, you'll see that we replaced the siding, roofing, and landscaping. We also added a large sliding windows in the living room.

The next picture shows the entrance from the backyard deck to the kitchen dining room. The large opening from the double doors make the transition from the home to the backyard feel super seamless. What you can't see in the pictures is the concrete gas fireplace built by the deck and roughly 400 sq ft home extension we built onto the house.

On the topic of extensions, the renovated garage you'll see in the pictures started off as a room with exposed framing and no insulation. We converted this garage space into a comfortable living space / functional home office. Garage to office conversions have been a popular option for most Bay Area homeowners these past few months!

Moving inside, we built the common area to be well lit by natural light. The materials used throughout the home stay consistent with the gentle pastels and natural colors. The natural stone in the kitchen does a wonderful job at adding some texture into the room.

Aside from the aesthetic upgrades, the home also features a 6 range Thermador cooktop with a stainless steel overhead exhaust, a newly built beverage nook, and newly renovated home office. We repurposed the garage of this home into a modern office with lots of outlets and an upgraded electrical system to handle the load of all the new appliances and musical instruments.

Sierra Ave, Richmond

ADU & Home remodel

20 weeks

The design for this home was inspired by Minimalist elements so you'll see a lot of geometric lines, natural colors, and natural materials all across the home. Starting with the kitchen, the white backsplash creates a clean contrast to the floating wood shelves. All the cabinetry is a flushed surface with elegant minimalist handles. Though this home has a simple design, simple doesn't have to mean limited. We built custom floor to ceiling cabinets with an inset coffee nook. The nook has lots of outlets and a matching backsplash to what we used in the kitchen.

Additional to renovating the home, we also built an ADU in the backyard to create another living space for guests or renters. If you live in the Bay Area, you know that these structures are an absolute gem to have on your property. The additional bathroom and bedroom is unique from the home's aesthetic but stays consistent with the Minimalist theme of clean geometric lines and natural colors. The bathroom you see here has a generous double sink vanity, herringbone cabinet patterns, and hexagonal tiles all across the floor. There's a whole lot of creativity in this bathroom. Why not be creative and have a little fun with your ADU builder!

Moving on to the bedroom, you'll see a lot of window opening to let in as much natural light as possible. The wood flooring lights up really well with all the natural light.

Hampel St, Oakland

Home remodel & room addition

18 weeks

This centrally located home in Oakland became the talk of the street after the remodel was finished. We ran with the vision of the homeowners to build a second story addition above the garage and renovate the entire home. Starting from the outside of the home, we replaced the roof and redid the stucco across the entire home. We took out the roof structure that was once above the garage door, reinforced that structures framing, and built out an entirely new room.

Moving inside, the homeowner's goal for the home was to install new appliances and a new HVAC system so to accommodate these changes, we upgraded the electrical system by replacing the electrical panels and wiring throughout the home. Additionally, we also installed new laminate floors throughout the home.

For the dining area, we took out a wall that separated the kitchen from the dining room and replaced it with a bar top island. The kitchen's aesthetic was built around the dark countertops so you'll notice the greys and whites used for the backsplash, cabinetry, and handles.

We also remodeled 2 bathrooms by installing entirely new tiles throughout the bathroom and this masterful niche. Lastly, you'll see the newly built home office which is located above the garage and the mudroom connected to the kitchen. Getting city approvals for these projects took a good amount of time due to the room extensions, garage renovation, and 2nd story addition but thankfully, we had a team to help expedite the process.

It is worth noting that the transformation of this home was such an improvement from the previous state of the home, before the remodel was complete the homeowners were able to sell the property for a profit and move to a different home.

The process of building an in-law unit or ADU is almost identical to the process of building a new home. The differences are with the occupancy limits, set back requirements, and other requirements that your general contractor would have to work with. Requirements for building in-law units or ADUs differ between each city's governing department so before you plan on building an ADU, it would be wise to first find out if you're allowed to do so in your property. Recent law changes to address the issue of housing shortages have made the process of building an ADU much easier and quicker. If you're looking for a more hands off process, contact us to and we'll do the legwork of finding out for you but if you're more of a DIYer and want to read on, a great resource is ADU California's website.

Preconstruction and architectural plans for your ADU

As with the new construction, we recommend that you start with a 3D design so that the project manager, engineer, and architect are all on the same page with what you want the end product will look like.  The cost of 3D designs for your ADU will depend on the size and complexity of the ADU. To give you a ballpark estimate, 3D designs for an ADU will run from $5,000 to $15,000.

These might seem like a steep price for designs but in our experience, a good set of plans have prevented mistakes that can end up costing tens of thousands and delay the project's timeline.

The cost and timeline for building an ADU or in-law unit

You can expect to spend $400 to $500 per square foot of your ADU for the labor and rough materials. This cost will differ for based on the complexity of a project but at Home Quality Remodeling, we have built ADUs with a budget of $250 per square foot. The most time consuming part of the ADU building process is getting the permits and plans approved. Some cities are quicker to respond and approve than others. Your 3D designs can come in handy here if your city's building department wants to conduct an aesthetic review of the finished project. Some cities do this to keep the aesthetic of a neighborhood consistent with other houses in the area.

Note that the type of finish materials you select for your ADU will likely drive up the cost so if you’re on a tight budget, choose your materials strategically. Ask your project manager for supplier recommendations. We have partnered with a variety of suppliers around the Bay Area to get discounts for our clients. We typically get materials 10% to 25% cheaper than retail price

The most significant cost driver in building an ADU or any structure for that matter is the type of finish material that the homeowner chooses. For example, going with a herringbone style kitchen backsplash versus a sheet of prefabricated tile will drive the costs of a project way up.

What's the difference between rough materials and finish materials?

Rough materials are typically standard non-decorative elements of a home. Here's a list of rough materials to give you an idea:

Finish materials are typically the decorative elements of a home. Note that the type of finish materials you select can drive up the cost of your project. Just as an example, you can buy prefabricated cabinets for $5,000 or get custom cabinets for $50,000. So work with your project manager or interior designer during the planning phase to select the finish materials so you’ll have a clear idea of the total project cost. 

Here's a list of some finish materials:

What ways can I finance building my ADU?

The good news is there are a ton of ways to finance the construction of an ADU. Certain cities have programs that are designed to help finance the building of ADUs within their cities. The City of San Jose for example, provides special financing through 'The Housing Trust Construction' loan program. Through this program, they offer construction loans to homeowners in the Santa Clara County and the city of East Palo Alto. They may have added more cities since we last complied this information so check their website: https://housingtrustsv.org/.
