Process and hiring
Permits
What your contractor should handle
In California, most structural work, ADUs, and many remodels require permits and inspections. A licensed GC identifies jurisdiction requirements, prepares submittals, and schedules inspections — so you are not left coordinating the building department alone.
Coastline works under License #813394 and treats permits as part of the project plan, not an afterthought.
Planning
Understanding construction timelines
Duration depends on scope, permits, material lead times, and site conditions. Kitchens often run weeks; custom homes run many months. Weather, inspections, and owner selections are the most common variables — not “surprises” if they are planned for.
Ask for a phase-based schedule: evaluation → planning → pre-construction → build → completion.
Budget
What drives project cost in California
Cost follows scope, finish level, structural conditions, access, and permit complexity. Coastal and hillside sites add engineering and logistics. Online “instant quotes” cannot see your property — a site visit and documented scope are how serious pricing is built.
Coastline does not publish fabricated averages. Ranges on service pages are directional only.
Process
What to expect during construction
Expect site protection, a single point of contact, regular updates, and a punch list before handoff. Dust, noise, and temporary access limits are normal — neighbor courtesy and daily cleanup are part of professional job-site standards.
You should always know who is on site and what happens next week.
Demolition
When a remodel needs demolition first
Selective interior demolition opens finishes and non-structural assemblies so a remodel can start clean. Full teardown clears a structure for rebuild. Both need utility planning, disposal, and — when required — permits and dust control. Opening walls early under a licensed plan reduces mid-project surprises.

Hiring
How to evaluate a California general contractor
Verify active CSLB license status, insurance, and relevant project experience. Ask who manages the job day to day, how change orders work, and how communication is handled. Clarity before contract is cheaper than conflict after mobilization.
