Building Department - FAQs

I’ve been asked to develop a green building program for my jurisdiction. Where do I begin?

The good news is there are many resources available to help communities develop voluntary and mandatory green building programs. The CALBO Green Building web page is an excellent place to start. You can find good information here, or at the very least, there are links that will direct you to other sites that can be of assistance. In the “Resources” section, there are several documents you may download that provide detailed information for developing green building programs and ordinances. Additionally, CALBO will be maintaining an up-to-date list of communities that have developed, or are intending to develop, green building programs in California.

I see there are lots of green building rating systems out there. How do I know which one(s) will be best for my community? Or, would we be better off developing our own rating system to suit our specific needs?

There are a number of excellent green building rating systems that have been developed across the country. Some are focused on residential construction, while others address non-residential green building. There is no need to “reinvent the wheel.”

When developing the plan for your green building program, it’s important to think about how to make your program as effective as possible. One way to do this is to research what other jurisdictions have done in your area. (See the list of community green building programs in the “Resources” section of this web site.) By incorporating features of neighboring programs into yours, you’ll be contributing to regional consistency. This consistency may take the form of how the program/ordinance is structured, what green building rating systems are being used, the way the program is implemented, or any combination of these. Regional consistency not only provides communities with opportunities to work together, but will make it easier for builders to incorporate green building features into their business practices since what they learn to do for one community they can apply in another.

Where can I get training to learn about green building?

There are a variety of instructional sources currently available and more are being developed. Listed below are some of the educational opportunities that are pertinent to green building in California.
  • Build It Green offers a Certified Green Building Professional program along with their GreenPoint Rater program. Build It Green will provide local training for local governments as well as the general community.
  • CALBO offers a full-day green building class at the annual Education Weeks in Concord and Ontario. This is a Green Building 101 course that provides a general overview of green building along with how green building relates to the building code. You will also learn the basics about developing green building programs and ordinances.
  • California Green Builder offers training to city and county officials as well as builders and builder associations. Training can be specific to the California Green Builder Program or more general in nature.
  • ConSol has been providing builders and city officials Energy Code training since 1995. ConSol is also a member of the D.O.E. Build America program which focuses on researching new building technologies. ConSol’s training can be tailored to your specific needs.
  • The International Code Council is developing a series of green building classes.
  • PGE’s Pacific Energy Center in San Francisco and the Energy Training Center in Stockton offer free training related mostly to energy issues, but are expanding their class offerings to include green building.
  • The Solar Living Institute in Hopland offers weekend courses on a wide variety of green building and sustainable topics.
  • Sonoma State University in Rohnert Park (45 miles north of San Francisco) offers a Professional Green Building Certificate program. This course requires attendance one Saturday a month for 12 months. There are a limited number of seats available for online students.
  • The U.S. Green Building Council offers a number of workshops related to their LEED® rating systems.
  • University of California at Davis offers a certificate program in Green Building and Sustainable Design.

I hear a great deal of discussion as to whether to implement a “voluntary” program or a mandatory ordinance. Can you provide any insight on this issue?

Whether to establish a voluntary or mandatory program depends on many factors. What has been directed by your city council or board of supervisors? What would the general community like to see? What kind of green building support services are available in your area? Are there designers who know how to incorporate green building into their designs? Are there green building consultants available to provide knowledge and expertise? Do local building material suppliers have green building products available for resale? Putting a mandatory ordinance in place without the necessary available support structure could undermine efforts to promulgate green building in your community. Some communities start with voluntary programs and then convert to mandatory regulations once the building community has had a chance to get educated. Others will start with a mandatory ordinance, but then set their compliance threshold levels low enough that it acts like a voluntary program. Compliance this holds could then be adjusted accordingly depending on how the market will react and what level of compliance elected officials will desire.

Whatever you do, it’s important to remember that effective green building programs, be they mandatory or voluntary, are sensitive to local and regional economies and work best when the public-private partnership is in balance. Government can “nudge” the private sector in the direction of green building and provide the impetus to develop green markets. At the same time, builders need to understand that green building is the wave of the future and they should work on re-tooling their business practices to incorporate green building into their everyday operations.

Can cities adopt a mandatory policy requiring green building for civic/public buildings?

Yes, cities may restrict their own practices and mandate that they themselves operate under more restrictive building standards than those imposed by state law, as long as those practices do not contradict the building code.

What are some of the legal considerations when developing a green building program/ordinance?

If your program is voluntary, there isn’t much to worry about on the legal side of things. Because it’s voluntary in nature, builders and property owners are participating on their own volition. With a voluntary program, there are no legal requirements.

Mandatory approaches, on the other hand, require careful consideration of the legal regulations at play not only at the local level, but especially at the State level. Because we enforce the California Building Standards Code, there are specific procedures that must be followed when making modifications to the State Code at the local level. Building officials in California are familiar with this process.

Since energy efficiency is a big part of green building, the California Building Energy Efficiency Standards are routinely made more stringent in order to comply with local green building requirements. Unfortunately, as of September 2007, only eight jurisdictions in California have gone through the proper procedures, which include filing an application with the California Energy Commission to amend the State Energy Code at the local level. Setting up a mandatory ordinance that is legally correct and defensible, is the most important consideration when looking to adopt local green building regulations. You will need to spend time with your legal counsel to ensure that the ordinance you propose doesn’t conflict with State law or other local ordinances. See the “Resources” section for more detailed information on legal considerations that apply to adoption of local green building ordinances.

If I decide to develop a green building ordinance, does it belong in the local zoning ordinance, or the local building code?

It all depends. As mentioned above, any local modifications to the State Building Code have to follow prescribed procedures established by State law. However, many green building measures found in a variety of green building rating systems are not considered “building standards” as defined in the CA Health and Safety Code. For instance, construction debris diversion and the use of drought-tolerant plants are included in the list of measures found in most of the green building programs, but there is no need to modify the State Building Code because they are not building standards. Measures such as these can be considered for placement into the local zoning ordinance because they can be considered land use issues.

On the other hand, modifying the CA Energy Code clearly is a modification of a building standard, which is not a land use concern. There are some requirements that don’t fall into either camp. For instance, establishing areas for recycling within a dwelling unit isn’t a land use issue and it isn’t a building standard that is subject to the requirements for local building code amendments. Where does this fall?

Some communities have decided that green building doesn’t fit well into either category and have set up green building requirements within independent titles of their respective municipal codes. One city has established a new “Sustainability” title in their local municipal code. Within that title are a Green Building Ordinance and an Energy Efficiency Ordinance. Other sustainability issues such as solar access, construction and demolition debris, and water conservation will eventually be included. Because of the issues related to global climate change and the recent decisions by the State Attorney General for local governments to address climate change in their General Plans, this approach could be a good one to support these concerns.

I understand the State is developing green building standards. Shouldn’t I just wait and see what they come up with before starting something in my own community?

There are a number of things going on in the legislature as well as at the Building Standards Commission. While it is too early to tell what the final outcome will be, it is clear that the State is, and will be, raising the bar for green building in California. In all likelihood, whatever is produced at the State level will complement what many local communities have already started. It’s never too soon to start getting a green building program going in your community. Work started now will only make for an easier transition in the future.

What is “green washing” and how can I avoid being labeled as such?

“Green washing” is a term used not only in green building circles, but anytime someone is presenting something as “green” when in fact it is not. For example, just because someone claims to be a “green” builder because he/she says so, doesn’t necessarily mean it’s true. There are a few ways to ensure that your green building program is recognized as green. First, it’s important to use or reference established green rating systems that are accepted by the industry as being green. While there are two green building standards currently being developed through the ANSI and ASHRAE standard development process, many of the mainstream green building rating systems, such as LEED®, offer credible means to verify that buildings are truly green. Third party verification is one means of confirming that projects in your program are green.

What is the difference between green building program “development” and “implementation”?

Developing a program has to do with organizing the structure by which all the rules and regulations are established. In the case of a mandatory program, this would be an ordinance. It will spell out what projects are covered by the regulations and which ones are exempt. It will specify which rating systems to use and what compliance threshold levels that must be attained. Enforcement mechanisms and penalties will be spelled out. Once the program has been defined and setup, it is now time to “implement” the program.

Implementation is the act of carrying out the program. Implementation will include developing procedures for taking applications, creating forms, training staff and the public, providing handout materials, hiring additional staff (if necessary), and simply taking care of the myriad of details that will need to be addressed in order to make your program successful. Be aware that many programs have suffered because there was not enough attention paid to developing a sound implementation plan.

We have no funds for a Green Building program. How are other communities dealing with this issue?

There is no free lunch. One way or another, there needs to be a way to pay for a green building program, whether it’s voluntary or mandatory. However, there are ways to coordinate resources and share the responsibility of financing this endeavor.

For those communities that have mandatory programs, there will need to be plan check and inspection staff to verify compliance. Some cities are increasing their fees to cover this aspect of the program. Some building departments are treating green building as a “special inspection” measure. In this case, the owner would pay for green building inspection just as they would pay for any other special inspector.

Alternatively, for an existing verfication program, such as Build It Green's Green Point rating is required, verification would be performed by a third-party rater. This approach relieves city staff of the extra work associated with documenting and CB verifying measures.

Green building provides benefits to other city/county departments that have resources to contribute. For instance, waste management agencies can reduce their overhead costs when builders divert large portions of their construction debris. Some waste management agencies have provided financial assistance to help with developing green building programs.

What is green home?

Green homes benefit homebuyers and the community at large. Builders who embrace green differentiate themselves in the marketplace through resource efficiency. Builders may also be rewarded with jurisdictional benefits. Homebuyers benefit now and in years to come from the green features.

What are some considerations when building a green home?

  • Lot Preparation and Design - Even before the foundation is poured, careful planning can reduce the home’s impact on natural features such as vegetation and soil; and enhance the home's long-term performance. Such preparation can provide significant value to the homeowner, the environment, and the community.
  • Resource Efficiency - Advanced framing techniques and home designs can effectively optimize the use of building materials. Careful material selection can reduce the amount of time and money needed for home construction, maintenance, and result in less jobsite waste.
  • Construction Waste Management - By working with a clean-up contractor, builders can recycle over 80% of their construction waste, often at no additional cost. Some clean-up contractors are also able to provide AB 939 documentation for their waste diversion.
  • Energy Efficiency - This is the most quantifiable aspect of green building. Building a better envelope and incorporating more energy efficient mechanical systems, appliances, and lighting into a home, yield long-term utility bill savings and increased comfort for the homeowner. A more energy efficient home also reduces the pressure on the electrical grid by reducing “peak load” and helps utilities avoid brown outs. Also, every kWh saved is a kWh that isn’t produced, and avoids the pollution associated with electricity generation.
    • A secondary consideration concerning energy efficiency is how much energy is embodied in the building materials themselves, in their transportation and assembly. Materials that are manufactured close to the job site have a smaller impact than items built across the country.
  • Inspections/Diagnostics - How is the home being verified? A third party inspector can provide an added layer of comfort in documenting the resource savings of a green home. In the current California energy code, third party inspections are one of the most cost effective ways to achieve compliance. There are benefits to making sure subcontractors are building to the specifications required by their builders.
  • Water Efficiency/Conservation - Concern with adequate supply is becoming widespread. Decreased indoor and outdoor water use can reduce utility bills. In many cases there are added benefits to water conservation, such as a healthier landscape (plants and turf are more often than not over-watered) and shorter wait time for hot water.
  • Comfort and Indoor Environmental - Effective management of moisture, ventilation, and other issues can create a more comfortable and healthier indoor living environment. Materials with low ow no VOC's such as paints and sealants, also improve air quality. Wood products without formaldehyde protect building occupants.
  • Operation, Maintenance and Education - Home owner guidance on how to optimally operate and maintain the green house

Do homes built under "green" program guidelines cost more to build?

Many green building techniques can be applied at little or no extra cost. Additionally, heating, cooling, and water use in green buildings often cost less so up-front costs to buyers can be offset in the long run.

Is "green" building more complicated?

The requirements vary from program to program but most include building to exceed energy efficiency standards; diverting at least 50% of construction and jobsite waste; reducing water use; and include guidelines for efficient lumber usage.

What are the differences between the major green building programs?

Many are points-based and can be regional or national in scope. Some help localities meet mandates in water and energy savings and waste diversion. Some are mandatory and some are voluntary.

What incentives do builders find most interesting?

The cities of Riverside, Costa Mesa and Anaheim, as well as the County of San Bernardino have incentive programs in place. The incentives include over the counter benefits, such as expedited plan checks and priority inspections, and fee waivers.

  • Fee deferrals, rebates
  • Faster plan check
  • Density bonus
  • Marketing support
  • Recognition from elected officials
  • Opportunity to be perceived as more socially responsible stewards of the environment
  • Monetary incentives

What are the benefits to a city?

By encouraging builders to go green, a city is providing a better housing product for its residents. A green home is a less costly home to operate, a more comfortable home, and a home that has less of an impact on the environment.

Do consumers want homes "green"?

Recent studies have shown that many homebuyers want green homes. People want lower ozone-depleting gas emissions, sustainable forests, and less landfill waste. Builders report that "green" homebuyers have higher satisfaction, knowing they have done something good for the environment.

What do homeowners have to give up to live "green"?

Most green homes look and feel just like traditional homes, except they use less energy, help power plants to emit fewer greenhouse gases, conserve water and wood, send less solid waste to landfills, provide better indoor air quality, and save homebuyers money on energy and water bills.

How does building "green" improve the environment?

  • Less energy usage which reduces CO2 emissions
  • Less water usage which protects our supply and reduced water delivery and treatment costs
  • Reduced water bills
  • Construction wastes reduce landfill consumption and help create new uses for second-hand products
  • Better indoor air quality because of advanced HVAC designs with MERV filtering and through increased use of low or no VOC materials.
  • Wood from sustainable forests ensure that the lumber being used is coming from responsibly managed tree forests or plantations, protecting our old growth forests.
  • Engineered wood makes use of recycled wood and results in stronger, straighter building materials.
  • Commissioning ensure that building systems work at optimum levels
  • High density and transit-oriented development values among used in transportation and sprawl
