What To Know About Building in California

California is a beautiful and diverse part of the US. Since we started delivering barn packages down the west coast in the late 1980s we’ve come to learn how the California mountains, coastlines, rivers, lakes, deserts and agricultural lands shape not only the landscapes and scenery, but also how they influence construction projects.

The diversity of California’s geography affects state building codes and plays a significant role in project permitting and structure design. Here we will share what we’ve learned so you know what to expect from the journey, and how you can make your project as efficient as possible

As with all things construction related, every project cost and timeline are unique no matter where you are building, but we’ve identified some common trends as we have engineered and shipped our structure kits throughout recent decades.

  1. Permitting timelines can be lengthy and require many assessments and reports of your land. Speak with your county office and begin any necessary land evaluations as soon as possible.
    • Your county office will be your biggest planning resource for your project. They will confirm if you can in fact build your desired structure at the desired location on your property, as well as provide information on specific assessments and reports that are necessary when applying for building permits in your area. They can also provide you with a list of professional services who can conduct any required steps.
    • Once you have confirmed that you can build on your property, we’ll work with you to outline your structure and design. We recommend you begin working with the necessary professional services as soon as possible. The goal here is to gather and account for any information that could potentially influence your structure design or halt your project before blueprint engineering begins. Once your necessary reports and assessments are complete, we’ll take care of the structural engineering of your blueprints.
  2. Barn Pros will engineer your blueprints to meet local building codes and then deliver them to you. The next step is to take your completed blueprints to an Energy Consultant, Cetertified Energy Analyst (CEA) or licensed architect (specializing in energy modeling and compliance) of your choosing to complete the necessary Title 24 energy report. Once you have this report along with your blueprints and completed site plan, you are ready to submit your building permit application.

Reference the appendix for a full list of county websites and links to the updated energy codes in full.

Submitting for and obtaining necessary building permits in your county will likely be one of the lengthiest parts of your project. Because of the geographic diversity of the state, there are often many assessments and reports of your land that need to be done before you can  submit a request for permits. We’ve found the most efficient way to line up these details is to work with your county to complete the necessary assessments while Barn Pros works to engineer your blueprints. This way there will be less down time between the permitting phase, engineering phase and start of construction.

What is Needed to Apply for Permits in California

  • Feasibility Assessment
  • Site Plan including any necessary property reports or assessments
  • Engineered Blueprints
  • Completed Title 24 Energy Report

Feasibility Assessment

The first thing we recommend is meeting with your county building department for a feasibility assessment of your land. This meeting will determine if your land can in fact host your desired structure and use case, at your desired location on your property. The county will look at your property information and proposed structure size, design, structure use and location to provide a list of necessary reports and assessments, the results of which will confirm if your land can support your project or not. The county can also provide a list of professional services you can work with to carry out these necessary evaluations and reports. This step is key and is essentially the green light for your project.

Site Plan

Once the county building department has confirmed your land can support your desired structure, the next step is to work with the necessary professional services to gather the required land assessments and reports and combine them into a site plan. At this time Barn Pros will work with you to confirm the layout, size and details of your structure and prepare to engineer your blueprints.

When your site plan contains all the needed land assessments and reports, Barn Pros will accommodate these details in your blueprints.

See the appendix for example site plan details and professional services that you may need to pursue.

Title 24 Energy Report

When you have completed all necessary land assessments and reports and Barn Pros has completed your structural blueprints, you will be ready to submit them to the Energy Consultant, Certified Energy Analyst (CEA) or architect (specializing in energy modeling and compliance) of your choosing to create your Title 24 Energy Report. This report accounts for your structure’s energy consumption and efficiency to ensure compliance with the California Energy Code. Title 24 Reports will encompass details such as:

  • The building envelope includes insulation, windows and doors, and air sealing.
  • Heating, Ventilation and Air Conditioning Systems (HVAC)
  • Water heating
  • Indoor and outdoor lighting systems
  • Appliances and electrical plug loads
  • Renewable energy systems such as solar panels, solar water heating or wind turbines.
  • Certificate of Compliance
  • Installation Certificates
  • Verification Certificates

Where to Find Permitting Information

Your county building department will be your best resource for scheduling, land feasibility assessment, and gathering additional information pertaining to permitting and site planning.

Some counties offer permit expediting services that assist you in navigating the permitting process. These services can be very beneficial in saving you time and energy while ensuring you have all the documents, reports and information needed to successfully apply for building permits. Ask your county building department if they offer any services like these.

Reference the appendix to find your county website.

Types of assessments and reports that may be required in your site plan.

No two site plans will be the same thanks to California’s varied terrain. With this in mind, common assessments and reports for your site plan may include the following:

  • Property information including lot size and shape, property lines and boundaries.
  • Existing topography, vegetation, structures, utilities, and bodies of water.
  • Proposed structure information such as footprint, dimensions, setbacks, building height, floor plans and elevations.
  • Necessary site improvements including driveways and access roads, landscaping, grading, drainage, fences, and walls.
  • Utility and services connections, septic systems, and stormwater management.
  • Regulatory compliance of zoning and easements
  • Environmental Impact Assessment
  • Fire Protection Plan
  • Septic system design
  • Air quality assessment

Reference the appendix for more details around potential land assessments and reports and contact your county building department to confirm which are needed for your specific site plan.
