Whether you need more living space to accommodate a growing family or you want to modernize a drab and dated home, chances are that a local remodeling and addition contractor in San Francisco has the answer.

First, have a clear idea of what type of project you’re looking for. By having clear parameters of the size and scope of your project, you’ll help contractors give you a reliable bid and add suggestions for the best use for your existing and new spaces.

Then, carefully research local companies. Research is the key to finding the best remodeling contractors in San Francisco, including those in the major neighborhoods of Sunset District, Richmond District, Mission District, Bernal Heights and Tenderloin, as well as those in the smaller districts.

Hire an Experienced Home Remodeling and Addition Contractor in San Francisco
Most remodeling companies and home addition contractors in San Francisco have experience with a variety of home makeover and home addition services including the following:

  • Home additions
  • Bathroom remodeling
  • Kitchen remodeling
  • Second-story home additions
  • Room additions
  • Garage additions
  • Bedroom additions 
  • Basement remodeling
  • Sunroom additions
  • Attic remodeling
  • Family room additions
  • Custom remodeling plans
  • Old house renovations

Experienced remodeling contractors are more likely to give accurate bids, create unique remodeling and addition plans, do a professional job and complete the project on time. So confirm that the San Francisco renovation contractor you’re considering has successfully completed several of the type of home addition or remodeling project you are hiring them to perform. Ask to see photos or even visit recent projects they’ve finished that are similar to yours.

The Value of Researching Remodeling and Addition Contractors in San Francisco
While it’s best to choose a Diamond Certified home remodeling and additions company because they’re rated Highest in Quality, that may not always be possible. If you’re unable to choose a Diamond Certified remodeling contractor in your area, you can improve your chances of hiring a good home addition company by checking out candidates on the Contractors State License Board website to ensure active license and workers’ compensation insurance. Violations will also appear on their license record, so you’ll know about recent infractions or serious customer grievances that have been processed by the state.

Then take time to verify company credentials. Remodelers who are members of local remodeling and home addition organizations and national building associations may offer better service, and you’ll be able to see their past records, including complaints and legal action.

You’ll probably spend weeks and even months dealing with your addition and remodeling contractor, depending on the work you’re having done. And as with any working relationship, it’s important you work well together. So you’ll want to consider the personal and professional qualities you value in a remodeling contractor. Promptness, good communication skills, honesty and cleanliness are important to many consumers, so decide what traits you want in the home addition and remodeling contractor you hire and don’t settle for less.

Be aware, though, that with some remodeling companies in San Francisco, the estimator you first deal with might not be part of the construction crew. That means there’s a chance the relationship you’ve built with them and the agreements you’ve made might not carry through to the rest of the job. If you’ve been talking with a local remodeling contractor, you may want to confirm with them who will be your contact during the remodeling or addition project and how they can guarantee the promises made during the planning process will be kept by the building crew.

Further Research on Good Remodeling and Home Addition Contractors in San Francisco
Now that you’ve done some initial research and have a clearer idea of what it is you want in your new addition and your contractor, talk with a few remodeling companies and home addition specialists in your area of San Francisco.

When interviewing remodelers, remember that many good addition and remodeling companies will not provide estimates over the phone without seeing the job first. Still, don’t feel obligated to set an appointment for an in-home estimate if you weren’t impressed with your initial contact with the contractor. If the local home addition and remodeling companies you’ve talked with don’t meet your expectations or can’t answer your questions satisfactorily, feel free to end the conversation and move on to the next high-quality remodeling contractor on your list.

Diamond Certified remodeling and home addition contractors are your best choice, because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a San Francisco remodeling company, you can have confidence choosing a Diamond Certified remodeling contractor from the greater Bay Area. Diamond Certified reports are available online for all certified addition and remodeling contractors. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

If you can’t find a Diamond Certified remodeling company within reach, you’ll have to do some research on your own. In that case, it’s sensible to call some references provided by the San Francisco remodeling companies you’re deciding among.

Keep in mind, though, that references provided to you by the home addition contractors are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. If you do call references on your own, request a list of the company’s 10 most recent customers. This will help avoid them giving you only the names of customers they know were satisfied. Then, use these questions to get you started in your interview of previous customers.

  1. Were you satisfied with the home remodel/home addition work from _(remodeling & addition company name)_?
  2. What was the type and scope of job they did for you (new room addition, kitchen remodel, bathroom remodel, whole home remodeling, sunroom addition, basement remodel, home renovations, etc)
  3. Did the San Francisco remodeling contractor and home addition company you hired complete the work on time?
  4. Did the contractor keep you up-to-date on the status of the project?
  5. Were there unexpected costs? If so, what were they for and were they avoidable?
  6. Did the San Francisco home remodelers show up on time?
  7. Did they clean up after finishing the home renovations?
  8. If you need home additions or remodeling work in the future, would you use this contractor again?
  9. Would you recommend them to friends or family?
  10. Can I visit your home to see the completed home renovations and room addition?

Before interviewing and choosing a good home remodeling company in San Francisco, including those serving the larger neighborhoods of Sunset District, Tenderloin, Richmond District, Mission District and Bernal Heights, decide the type of project you’re looking for and the scope of the work you want done. You should also know the budget range you’re looking to stay within. This will help you express yourself to the contractors you talk to, and will give each remodeling contractor and home addition builder the chance to bid on the same project. And it will help you define boundaries so that you don’t end up getting more than you want or need.

Knowing the scope of your home addition or renovation will give you a good idea of whether you want to stay in your home during the work or relocate while the construction is in process. Home renovations and additions can be loud, dusty and disruptive, but some are more intense than others. Consider the rooms you’re having remodeled or the location of the home addition and ask the home remodeling and addition contractors you interview whether you’ll be able to stay in your home during the work. You may want to consider moving to another location for the duration of the project if important rooms (like your kitchen and bathrooms) will be under construction, or if the contractor expects major interruptions in electricity or water.

Sign a Contract with a Good Local Remodeling Company
Once you’ve found the San Francisco remodeling and addition contractor that is best suited to your job, you can move forward by obtaining a detailed estimate and signing a contract. The contract should include the price, start and end dates and any special requests you’ve agreed upon with your local home renovation contractor. You’ll also want to confirm any warrantees or guarantees at this time and make sure they’re in writing in the contract.

Read through the estimate and be sure you understand all terms and limitations before you sign the contract. The contract you sign with your San Francisco remodeling company is binding, so for your protection, never sign a blank or incomplete estimate.

Prepare for Your Home Remodel and New Home Addition in San Francisco
Provide adequate storage space if required. Some remodeling contractors in San Francisco have facilities or travel trailers in which to store remodeling materials and building equipment, but others expect homeowners to provide a clean, dry and accessible storage area for these materials. Ask your home renovation contractor if you’ll need to have space for materials and, if so, how much space is needed.

Supply clearance and parking space for work trucks. Construction vehicles are often large and may need special parking consideration depending on the size of your driveway or available street parking. Ask your contractor how many work vehicles will need parking space, and whether trailers or other large vehicles will be on site daily. It may also be wise to walk through your property with your San Francisco remodeling contractor and have them advise you of any clearance issues, lawn ornaments or potential hazards that you can move or minimize before the work begins.

Prepare your home for construction dust. Remodeling and new addition construction is often a dusty job. Many contractors will provide taping and plastic barriers to prevent dust and construction debris from entering areas of your home that aren’t being remodeled or renovated, but you may be able to save time and money by preparing your home yourself. Talk with your remodeling contractor about steps you can take before the remodeling begins.

Move and store unnecessary decoration and other items. Remove furniture, decorations, rugs and other movable objects from the rooms to be remodeled. This will protect them from dust and damage, and will allow your remodeling contractors to move freely and avoid injury. You may also want to temporarily store any heirlooms or expensive items that are located in high traffic areas of your home. Keep in mind that construction can cause items to shift and fall from shelves and walls, and take down any artwork or decorations.

Keep children and pets away from the construction area. Your remodeling and home addition contractors shouldn’t be expected to watch out for kids and pets. So for their safety, keep any household pets or children out of the area when your remodeling contractors are working. It’s wise to keep everyone away from the construction area even when no remodelers are working as building tools, unfinished construction and exposed wires may pose a safety hazard.

The most popular types of remodeling and addition projects for contractors in San Francisco are listed below, including examples of each kind of remodeling job.

Basement Remodeling
Basement renovations are a popular home remodeling project. Most basement renovations turn unused basement space into a finished basement with a family room, bedroom, basement bathroom, recreation room (rec room), or other usable space. San Francisco basement remodeling plans mayinclude basement design, the installation of basement walls, new carpeting and flooring, a basement fireplace and a basement bar.

Home Renovations
Like home remodeling, home renovations can change the design, functionality and appearance of your home’s interior. Home renovations, whether in the kitchen, bathroom, basement, bedrooms or living rooms, often start with home renovation plans from a qualified San Francisco remodeling contractor and include new house interior designs, new flooring and wall coverings, new countertops and cabinets, construction of new walls and home improvements like new fireplaces and new lighting.

Room Additions
Room addition to homes can be any size and may include bathroom additions, family room additions, modular home additions, sunroom additions and bedroom

additions. Room additions are often a complex process. Since the new room addition plans should match your existing home and must correctly connect to the existing structure, it’s wise to hire an experienced San Francisco home addition contractor to draw up your room addition plans and complete the new addition.

Kitchen Remodeling
Kitchen remodeling includes renovations of the design, style and structure of a kitchen. A kitchen remodel may comprise new kitchen design plans, kitchen counters, kitchen cabinets, new kitchen appliances, new flooring and new kitchen lighting.

Bathroom Remodeling (Bath Remodeling)
A minor bathroom remodel will change the appearance of an existing bathroom, while a larger-scale bath remodel can change the size and usage of an existing bathroom. Most bathroom renovations in San Francisco include new bathroom fixtures, paint, bathroom flooring, bathroom tile, bath cabinets, new showers and bathtubs, new bathroom mirrors and even new bathroom floor plans.

Home Addition Building
Home additions, including master bedroom additions, family room additions, garage additions, in-laws quarters, mud room additions, second-story additions, kitchen extensions, sunroom additions, dormer additions, front porch additions and bonus room additions, are a great way to add value and extra space to existing homes.

Sunroom Addition
Also known as four-season rooms, sunrooms generally cost less than regular home additions. They are a supplemental home addition (rather than a functional or necessary home addition, like that of a bathroom addition, kitchen or bedroom addition) that provide extra space for reading and entertaining. Many sunroom additions come in the form of a prefabricated kit and do not include central heating or cooling systems.

Home Remodeling
Home remodeling, done either as a single-room remodeling project or as an entire home renovation, includes changing the appearance and even the design of the home. Most home remodels in San Francisco include new home floor plans and home improvements such as new flooring, new windows, kitchen and bathroom remodeling, basement remodeling, attic renovations, new paint, new appliances and other home interior renovations.

Garage Addition
Garage additions create more space for vehicles, storage and even future living space. Garage plans can be drawn to add on to existing garages and existing homes, or can be free-standing garages. If you have future plans of adding a bathroom or renovating your garage to create living space, you can have your San Francisco addition builder install plumbing and electrical in your new garage addition.

Custom Remodeling Plans
Home remodeling contractors in San Francisco can create custom remodeling plans based on your existing home and your requirements and wishes for your home remodel or addition.

Easy Conflict Resolution with San Francisco Remodeling Contractors
The best way to avoid messy misunderstandings and disagreements with your remodeling and addition contractor is to choose a trustworthy, experienced local addition contractor in San Francisco.

But if a disagreement does occur between you and your home remodeler, the most direct route to solving the problem is talking directly to your contractor. Most local builders are proud of their reputations and are invested in keeping their customers happy.

If your situation requires talking with your remodeler to find a resolution, remember these tips to increase your chances of getting a good result:

  • Meet in person with your contractor immediately when you have a complaint or a concern with the remodeling design, remodeling crew, materials or workmanship. Don’t wait until the job is done to bring up your concerns.
  • Revisit your contract with your remodeling and addition contractor and try to verbally resolve the problem.
  • Write down your complaint and, if possible, photograph the workmanship or products you’re concerned about. Also document the times you contacted your San Francisco remodeling contractor and their response.
  • Set a deadline with your contractor for resolution of your complaints. Be up front with them that you’re willing to work toward a mutually-beneficial solution.
  • If you do not get an appropriate response from your contractor, you may want to consider calling a local building inspector or hiring a remodeling expert to neutrally evaluate the problem.
  • You may legally withhold payment until the dispute is resolved.
  • File serious grievances with the Contractors State License Board.
  • Contact your state attorney general if you are considering pressing charges against the remodeling contractor for serious violations.
  • Fire the contractor as a last resort. Releasing the remodeling company can result in lengthy project delays and costly lawsuits.

Q: Why would I want to remodel or add to my home?
A: Remodeling can modernize your home, improve energy efficiency, and give you a new sense of pride in your home. Many San Francisco homeowners find that home remodeling projects allow them to upgrade their current home so that they’re happier living in their home and increase the resale value of their home. Like home renovations, home additions can add more usable space to a home. Whether you add a sunroom, a new garage or a bedroom addition, home additions add square footage and usability to your house.

Q: Why should I hire a remodeling and addition contractor for my project?
A: DIY stores and home improvement centers may carry many of the tools and materials for your home remodeling and addition project, and some homeowners certainly can take on these projects themselves. However, many homeowners find it saves them time, money and frustration to hire a competent, experienced remodeling contractor for their home renovation. A good remodeling and addition contractor will help you plan, execute and finish the project with much less hassle than you can expect when taking on a project yourself.


Q: How much will my remodeling project/home addition cost?
A: The cost of home renovations depends on the size and scope of your project and the quality of materials used for the addition or remodeling. When getting estimates from local remodeling contractors and home addition builders in San Francisco, make sure you’re asking the contractors to big on the exact same scope, size and materials in order to get accurate bids.

Q: I have three estimates and they vary greatly in price. Why is this?
A: It’s not uncommon for prices to vary from contractor to contractor. But if the gap between the highest price and the lowest price seems too substantial to be correct, or one bid is much higher or lower than the others, talk with the contractors again. It may be that one contractor didn’t understand the scope or details of the project they were bidding. Ask the remodeling contractors to fully explain their bids, and if they are vague about their answers, move on to the next contractor. Beware of bids that seem artificially low, as some home renovation contractors purposely underbid jobs and then tack on expensive change orders during the construction.

Q: How long do home remodels and additions take?
A: Depending on the size and scope of your project, your remodel may take a few weeks to a few months and room additions can take several months. Problems found during demolition, unforeseen challenges and the skill of your contractor can also add to the timeline. It’s important to get a clear and reasonable timeframe estimate from your San Francisco remodeling contractor and home addition builder when getting initial cost estimates.

Q: How much value will my addition or renovation add to my home?
A: The amount of value added to your home depends greatly on the renovation you choose and the quality of the workmanship and materials. If you’re planning to live in your home long-term, you may find that your room addition and home renovation will add more to your quality of living in your home, even if it doesn’t add to the resale value of your home. On the other hand, if you’re planning to sell your home soon, you may want to consult with contractors and real estate agents about which home additions and remodeling projects will add the most value to your home.

Q: Do I need to hire an architect, or can my San Francisco remodeling contractor and addition builder draw my home renovation designs?
A: Depending on the size and scope of your project, there are pros and cons to hiring an architect to draw up home remodeling plans and hiring a remodeling contractor who offers design/build services for home renovations. Here are a few to consider:

  • A general rule of thumb that many builders follow is that if you’re tearing down walls or moving walls, or if your project includes an addition and new construction, hire an architect.
  • Architects are trained to look beyond the outward design and consider the usability of a space, local building codes and zoning regulations, and can draw a complete set of home remodeling and home addition plans.
  • Some design/build remodeling contractors in San Francisco can offer lower costs and shorter construction timeframes by providing both home designs and building services.
  • Some San Francisco remodeling contractors prefer to do their own designs in-house and have the ability to draw home remodeling and addition plans in-house.
