An asbestos survey conducted by a laboratory-verified consultant is necessary before proceeding with any commercial renovation activity in California, and if paint is going to be scraped, sanded, or torn down, then the paint should be tested for the presence of lead too. Whatever is found in the process should be taken care of by a licensed abatement contractor according to Cal/OSHA guidelines for workers, air districts' notice, and hazardous waste laws before embarking on any construction activity. While asbestos-related activities are independent of the time of construction of buildings, the 1978 date is significant with respect to lead paint.
Learning about California's Strict Compliance Requirements for Buildings Built Prior to 1978
There is a lot of cross-agency overlap concerning one tenant improvement. Specifically, the Cal/OSHA Asbestos Standard in Title 8, §1529 demands a determination of where and how much asbestos materials there are within a structure prior to work commencing. There is an additional requirement from air districts. The Bay Area Air District, Reg. 11, Rule 2 requires that there be a survey done by a certified individual, involving laboratory analysis of the suspicious materials, prior to any demolition or renovation, with an exception made for four or fewer residential units. Projects located in Sacramento are governed by SMAQMD Rule 902.
On the other hand, lead is a different story. The Cal/OSHA construction lead standard in §1532.1 covers any construction activity where there is a potential exposure to lead up to 10 µg/m³. There is a CDPH certification from Title 17 in regards to lead construction in residential and "public" buildings that include retail and office buildings but not industrial ones. On the contrary, the federal RRP rule is applicable to pre-1978 housing and child occupied facilities.
High-Risk Renovation Tasks That Disturb Asbestos and Lead in Commercial Settings
The presence of asbestos in ceiling texture, flooring and adhesives, joint compound, pipe insulation, and roofing materials makes it constantly disturbed by routine TI work. Drywall demolition, ceiling scraping, floor stripping, core drilling, and surface preparation are some common examples.
It’s just as much of a task-driven material, too. Under Cal/OSHA, manual drywall demolition, scraping, and heat gun work fall under Level 1 tasks, while manual sanding or power tool cleaning with dust collection comes under Level 2. In the absence of an exposure assessment showing no overexposure, employers need to assume overexposure and provide respirators, protective clothing, and regulated work areas. In terms of housekeeping, HEPA vacuum containment is required over sweeping, while trigger-task work disturbing 100 square feet or more of material containing at least 0.5% lead needs notification to Cal/OSHA 24 hours before.
The Critical Pre-Renovation Survey and Testing Process
Scope comes first: what walls, ceilings, floors, and systems the TI will impact. Next, the CAC (or site surveillance tech) conducts a physical inspection and samples all the potentially hazardous materials. These samples are analyzed in a lab. A visual walk through does not qualify as a survey. Note the critical Bay Area requirement that testing and sampling is required. Lead requires no less rigorous an approach. Cal/OSHA classifies as hazardous to workers coatings that contain 0.06% or more (600 ppm) of lead content by dry weight. Painted surfaces are tested, even walls and trim scheduled for demolition.
The survey report provides input into the abatement specification, containment, worker protection, and disposal plan. The report is used for the air district filing. The Bay Area air district notification must be filed at least 10 days prior to the start of a demolition or renovation project. The air district notification applies to all demolitions and renovations involving 100 square feet or more of asbestos. CAL INC performs all types of asbestos, lead and mold surveys.
The Reasons Why Experienced Property Managers Work With CAL INC
For 35+ years, CAL INC has been providing environmental cleanup services from Vacaville, operating within the regions of Oakland, Sacramento, and all over Northern and Central California. This involves operating in various air districts and related documentation. The company holds the California state licenses for General Engineering (A), General Construction (B), Asbestos (Asb) and Hazardous Materials (Haz). The company is a member of ISNetworld, which is a widely used contractors' management system.
From the perspective of a property manager, the advantage here is the involvement of a single team that will be responsible for conducting surveys, asbestos abatement, lead paint abatement, demolition and waste removal. Survey results become part of the abatement plan right away.
Maintaining Project Schedules and Budgets through Proactive Environmental Planning
Surveying should come before completion of the designs, not during the middle of demolition. If an environmental issue is discovered at the middle of the demolition, then work will stop but the process of survey, notification, and abatement will continue with the complication of having tenants and sub-contractors as well as leasing agreements to consider. Account for the notice period and allow for the laboratory turnaround time, which is normally two to five working days with 24-to-48-hour rush option for an extra fee.
FAQs
How much does an asbestos, lead, or mold survey cost?
The cost depends on the size of the building, the number of materials sampled, and the type of survey needed. Contact CAL INC with your project address and scope of work, and we can review the site and provide a quote.
What is the difference between asbestos abatement and asbestos removal?
Abatement is the broader term for reducing or eliminating an asbestos hazard, which can include removal, encapsulation, or enclosure. Removal means taking the material out completely. The right method depends on the material’s condition and your renovation plans, which a survey helps determine.
Is lead paint dangerous if it isn’t disturbed?
Intact lead paint in good condition is generally lower risk. It becomes a hazard when it is sanded, scraped, heated, or demolished and releases dust. Testing before renovation shows whether lead is present so the work can be planned safely.
Can tenants stay in the building during abatement work?
It depends on the location and scope of the work. Abatement is typically done inside containment to protect nearby areas, and CAL INC can review your project to determine whether tenants can stay or whether certain areas need to be vacated.
What happens to asbestos and lead waste after it is removed?
Asbestos and lead waste is sealed, labeled, transported, and disposed of at approved facilities under state and federal regulations. CAL INC provides hazardous waste hauling and disposal, so removal and disposal can be handled by one team.
