Comprehensive Fire Safety Solutions for ADUs
We design and install systems that meet Pasadena and California codes while fitting each ADU layout. Our approach focuses on detection, suppression, alarm integration, and safe egress to protect occupants and property.
Smoke and Carbon Monoxide Detector Installation
We place photoelectric smoke detectors in or near sleeping areas and along circulation paths to catch smoldering fires early. We specify combination smoke and carbon monoxide units where code and layout permit, and we include battery backup and hardwired interconnection so all alarms sound together during an event.
We test detector placement against occupant sleeping patterns and common ignition sources such as kitchens and heaters. We label and document each device location for inspections and homeowner reference. Our installation includes user instruction, a written maintenance checklist, and guidance on sensor replacement intervals.
Custom-Designed Fire Sprinkler
Systems
We size sprinkler systems to the ADU footprint and water supply capacity to avoid overdesign and ensure rapid activation. For homes with limited pressure, we offer grid or single-pipe residential systems and specify escutcheons and recessed heads to minimize visual impact.
We locate sprinkler heads to provide full room coverage, with special attention to kitchens, living rooms, and any attic or utility spaces. We coordinate piping routes with other trades to avoid future penetrations, and we perform flow and acceptance tests required by local fire authorities.
Integrated Fire Alarm System Solutions
We integrate smoke, CO, and sprinkler signals into a single alarm panel so one event triggers whole-unit notification. We choose panel features based on ADU size, adding relay outputs for linked main-house systems or for monitored alarm services when requested.
We include audible and visual notification that meets accessibility guidelines when needed. We provide documentation for connection points, wiring diagrams, and commissioning reports for the AHJ. Our technicians demonstrate system operation and hand over labeled controls for owner use.
Our Fire Safety Systems Installation Process for ADUs
We assess your ADU layout, specify detectors and sprinklers, obtain required permits, and install fully integrated systems that meet Pasadena and Los Angeles County rules. Our process centers on accurate measurements, documented plans, and tested operation.
Personalized System Assessment and Design
We start with an on-site walk-through to measure room dimensions, ceiling heights, and primary risk areas such as kitchens and furnace closets. We document door and window locations and inspect existing wiring and plumbing to determine connection points and routing needs.
We select specific devices by model and placement, for example photoelectric smoke detectors in sleeping areas and sealed waterflow switches for sprinkler risers. We prepare a floor plan showing exact sensor and sprinkler head locations plus wiring runs and valve placement.
We produce a written scope that lists device types, power sources, battery backup plans, and estimated water demand for sprinklers. This scope becomes the basis for permits and cost estimates. We review the plan with you and adjust for aesthetics and future access.
Permitting and Regulatory Compliance
We prepare permit-ready drawings that match Pasadena building department and Los Angeles County fire code requirements. Drawings include device legends, riser diagrams for sprinkler systems, and calculations for hydraulic demand when sprinklers are required.
We submit applications, respond to plan check comments, and schedule required inspections. We work directly with local fire marshals and plan check staff to resolve questions about alarm tie-in, annunciation, and means of egress lighting.
We track permit status and provide you with copies of approvals and inspection sign-offs. We confirm code items such as CO alarms in sleeping areas, interconnection of smoke detectors, and access to shutoff valves before moving to installation.
Professional Installation and System Integration
We install devices using industry best practices and manufacturer instructions. Our technicians mount detectors at specified heights, run wiring in conduit where required, and test voltage at each connection point before finalizing terminations.
For sprinkler systems, we install pipe, valves, and trim, then perform hydrostatic tests and make hydraulic adjustments. For alarms, we program zone maps, sounder settings, and interconnect logic so a single trigger alerts the whole ADU and, if requested, links to the main residence or a monitoring service.
We run a full acceptance test with you present, demonstrating how to silence, test, and maintain each component. We provide a packet with as-installed drawings, device serial numbers, test results, and routine maintenance tips to keep the system code compliant.

Frequently Asked Questions About Fire Safety Systems Installation for ADUs
What fire safety systems are required for ADUs?
ADUs require comprehensive fire safety systems including NFPA 13D compliant fire sprinklers, hardwired smoke detectors with battery backup in bedrooms and hallways, carbon monoxide detectors near sleeping areas if gas appliances are present, and fire-rated construction materials for specific assemblies. Additional requirements include fire-rated drywall for shared walls, one-hour fire separation assemblies between attached ADUs and primary residences, tempered safety glass near exit doors, emergency egress windows in bedrooms meeting minimum size requirements, and proper fire blocking in wall and ceiling cavities per California Building Code and Pasadena Fire Department standards.
Do ADUs need fire sprinklers in California?
Yes, ADUs in California require automatic fire sprinkler systems compliant with NFPA 13D residential standards regardless of size or whether they're attached, detached, or garage conversions. This requirement applies statewide under the California Residential Code and cannot be waived even for small studio ADUs. Fire sprinkler systems must include adequate heads for coverage in all habitable rooms, proper water supply with sufficient pressure and flow, backflow prevention devices, and inspector test valves, with installations coordinated through licensed C-16 fire sprinkler contractors and approved by local fire marshals.
How much does fire sprinkler installation cost for an ADU?
Fire sprinkler installation for ADUs typically costs between $3,500 and $8,000 depending on square footage, number of sprinkler heads required, water supply configuration, and system complexity. Costs include CPVC or PEX sprinkler piping, residential sprinkler heads (usually 4-8 heads for typical ADUs), backflow preventer installation, connection to domestic water supply or dedicated fire service line, system testing and certification, permit fees, and fire marshal inspections. Larger ADUs, properties requiring water meter upgrades, or installations needing dedicated fire risers increase total expenses.
What's the difference between residential fire sprinklers and commercial systems?
Residential fire sprinklers (NFPA 13D) use lower water pressure, fewer sprinkler heads, and are designed for life safety by controlling fires until occupants escape, while commercial systems (NFPA 13) use higher pressures, more comprehensive coverage, and aim to fully suppress fires for property protection. Residential systems typically operate at 7-15 PSI with quick-response heads covering 12-16 feet per head using multipurpose CPVC or PEX piping integrated with domestic water lines. Commercial systems require 20-50 PSI, dedicated fire risers, steel pipe, more frequent head spacing, fire department connections, and are significantly more expensive and complex than ADU residential installations.
Do I need smoke detectors and carbon monoxide detectors in my ADU?
Yes, ADUs require hardwired smoke detectors with battery backup in every bedroom, outside each sleeping area in hallways, and on every level of multi-story units, plus carbon monoxide detectors within 10 feet of bedrooms if the ADU has gas appliances, fireplaces, or attached garages. Detectors must be interconnected so activation of one triggers all alarms throughout the ADU, meet UL 217 standards for smoke alarms and UL 2034 for CO detectors, and include photoelectric or dual-sensor technology. Pasadena Master ADU Builder ensures all detector placement meets California Residential Code Section R314 and R315 requirements during construction and final inspections.
