Pasadena, California is renowned for its historic neighborhoods, hillside estates, and bustling commercial corridors. But beneath the surface lies a complex foundation of varied soils, slope challenges, and regulatory considerations that make precision drilling essential for long-term structural stability. At Farr Construction Co., we provide comprehensive drilling services in Pasadena, designed to meet the diverse needs of contractors, property owners, and developers throughout Los Angeles County.
Our team brings over 65 years of field experience to every job, offering thoughtful, efficient, and regulation-compliant drilling solutions. Whether the project calls for geotechnical soil sampling in preparation for a new foundation, or deep pier and caisson drilling to stabilize hillside structures, we understand the demands of Pasadena’s unique terrain and stringent building codes.
From the foothills of the San Gabriel Mountains to the flat urban zones near Old Town Pasadena, drilling solutions must be tailored to local conditions. Our services begin with geotechnical drilling and soil analysis, critical for informing the design and placement of structural supports.
Once site conditions are assessed, we proceed with caisson and pier drilling to establish a secure, load-bearing base for any construction, especially in hillside locations like Linda Vista and San Rafael Hills.
We also provide trenching and utility boring for water, sewer, electrical, and telecom installations. In older parts of the city where underground utilities may be outdated or require careful mapping, our non-invasive boring techniques minimize disruption while meeting infrastructure upgrade goals.


For properties requiring erosion mitigation or slope stability, we offer retaining wall drilling and anchor installations, ensuring hillside integrity and compliance with Los Angeles County hillside development standards.
Whether you’re rebuilding after soil movement or preparing a new lot for development, we work closely with geotechnical engineers, structural designers, and city officials to ensure every step aligns with code.
These tailored solutions allow us to address Pasadena’s soil conditions, elevation changes, and preservation requirements with accuracy and care.
Drilling in Pasadena demands strict adherence to environmental regulations and construction ordinances. Our team is well-versed in Pasadena’s permitting process, California’s environmental policies, and OSHA safety protocols.
We prioritize site safety, sediment control, and minimal environmental disruption. Dust suppression, noise control, and proper handling of drill cuttings are part of our standard operating procedures, especially in environmentally sensitive or stormwater-adjacent areas.

Our longstanding presence in Los Angeles County and successful track record across Pasadena have made us a reliable partner for homeowners, builders, municipalities, and civil engineers.
Whether you're preparing to build a custom home, upgrade public infrastructure, or reinforce a hillside structure, Farr Construction Co. delivers drilling solutions you can trust.
