Project timelines vary considerably depending on the scope of work, the jurisdiction, the condition of the existing property, and the number of outside consultants involved.

A smaller remodel may move from design into permitting relatively quickly, while an addition, ADU, multifamily project, or complex property development may require several months of research, design, engineering, documentation, and agency review.

Permit review timelines are controlled by the city, county, or other reviewing agency and can change based on workload and project complexity.

At the beginning of the project, we will outline the anticipated phases, identify major dependencies, and explain which portions of the schedule are within our control.

Many residential improvements require permits, especially when the work affects structural components, electrical systems, plumbing, mechanical systems, fire safety, occupancy, building use, or exterior development.

Even work that appears minor may trigger code or zoning requirements depending on the property and jurisdiction.

Before beginning construction, we can help research the property, review the proposed scope, and communicate with the appropriate agency to determine what approvals may be required.

Yes. Coastline can act as the owner’s representative during the permit process.

Depending on the project, this may include preparing application materials, coordinating required consultants, submitting documents, communicating with agency staff, tracking comments, organizing corrections, and responding to plan-check requirements.

Some approvals, fees, reports, and professional services must still be completed or paid for by the property owner, but we help organize the process and keep it moving.

Feasibility is the process of determining whether a project appears possible before detailed design begins. This may include zoning research, permit history, setbacks, utility availability, site constraints, agency conversations, and preliminary consultant input.

Design is where we explore how the project should function, look, and fit the property. This may include floor plans, layout options, exterior concepts, and three-dimensional views.

Construction documents are the technical drawings and coordinated consultant documents used for permit review and construction.

Not every project requires the same process, but separating these phases helps prevent clients from paying for detailed drawings before important property questions have been answered.

It depends on the project.

Residential projects can be designed and documented without an architect. Other projects may require a licensed architect, structural engineer, civil engineer, energy consultant, geotechnical professional, surveyor, or other specialist.

We help identify which professionals are likely to be required and coordinate their work with the overall project.

We can help establish an early project direction and identify major cost drivers, but Coastline is not a general contractor and does not guarantee construction pricing.

During early design, we may help clients seek preliminary contractor feedback or compare the likely cost implications of different options.

As the design becomes more detailed, contractors can provide more accurate estimates based on the drawings, specifications, site conditions, and current market pricing.

Residential design and property improvement are the core of our work, including ADUs, additions, remodels, conversions, and new residential development.

We also support unique planning and design projects for organizations, nonprofits, religious institutions, property owners, and small developers.

These projects may include site planning, feasibility research, space planning, consultant coordination, permitting strategy, public-agency communication, and project organization.

Coastline Design & Development primarily serves San Luis Obispo and Santa Barbara Counties, including incorporated cities, unincorporated county areas, and community services districts.

Our experience includes working with a variety of local planning departments, building departments, fire authorities, utility providers, and technical consultants throughout the Central Coast.

Helpful information includes the property address, assessor’s parcel number if available, a general description of the project, photographs, previous drawings, survey information, permit records, title documents, or any correspondence you have received from an agency.

It is completely acceptable if you do not have these items yet. We can help identify which records are needed and where to begin.
