Everything Involved in Developing Your Architectural Plans
Architectural plans involve more than drawing floor plans. ATP coordinates every component of the design documentation process — ensuring your plans are complete, code-compliant, and ready for city submission.
Site Analysis & Zoning Review
Before design begins, ATP reviews your property conditions, zoning classification, setback requirements, height limits, and any site constraints that will affect the design — identifying issues before they become corrections.
Schematic Design
Initial design concepts and layout options developed based on your goals, property conditions, and zoning parameters — allowing you to review and refine direction before full plan development begins.
Construction Documents
Full architectural plan sets developed to construction document standards — detailed enough for contractor bidding, city plan check submission, and field construction.
Structural Coordination
ATP coordinates architectural plans with structural engineering requirements — ensuring design intent and structural systems are aligned before submission.
Plan Check Support
When the city issues corrections on architectural plans, ATP reviews each item and coordinates revisions to keep your approval on schedule.
How Architectural Plans Work With ATP
Every project starts with a clear design process — from initial consultation through permit-ready plan delivery. Here's how ATP develops your architectural plans from start to finish.
Consultation
ATP reviews your property conditions, project goals, zoning requirements, and overall feasibility. This is where we determine scope, identify any site constraints, and outline the design path forward. No commitment required at this stage.
Site Analysis & Zoning Review
ATP reviews your property against local zoning ordinances, setback requirements, height limits, and any additional code standards that will shape the design before work begins.
Schematic Design
Initial layout concepts and design direction are developed based on your goals and site conditions — allowing you to review, refine, and approve direction before full plan development begins.
Construction Documents
ATP develops your full architectural plan set — floor plans, elevations, site plans, and all documentation required for city plan check submission.
Structural Coordination
Architectural plans are coordinated with structural engineering requirements to ensure design intent and structural systems are fully aligned before submission.

Frequently Asked Questions About Architectural Plans
Can ATP develop architectural plans without committing to construction?
Yes. ATP provides architectural plans as a standalone service. Design and construction are separate engagements — you are not required to build with ATP in order to work with us on plans.
What is included in a full architectural plan set?
A complete architectural plan set typically includes floor plans, elevations, site plans, and all documentation required for city plan check submission. The specific components required vary by project type, scope, and jurisdiction — ATP will outline exactly what is needed during consultation.
How long does the architectural design process take?
Design timelines vary depending on project complexity, scope, and the number of revision cycles required. ATP will provide realistic expectations based on your specific project during consultation.
Can ATP develop plans for an ADU or room addition?
Yes. ATP develops architectural plans for ADUs, room additions, and structural expansions — coordinated with zoning requirements and existing site conditions.
Does ATP develop commercial architectural plans?
Yes. ATP provides architectural plans for ground-up commercial projects including retail, office, warehouse, and mixed-use developments — prepared to commercial occupancy and code standards.
What happens if the city issues corrections on my plans?
Plan check corrections are common and expected on most projects. When corrections are issued, ATP reviews each item, coordinates required revisions, and manages resubmittal to keep your approval on schedule.
Can ATP take over plans that were started by another architect?
This is determined on a case by case basis during consultation. ATP will review existing documentation and advise on the best path forward based on the current state of the plans and project requirements.
Do architectural plans expire?
Permitted plan sets are typically valid for a set period from the date of approval — after which a renewal or resubmittal may be required if construction has not begun. ATP will advise on any expiration considerations relevant to your specific jurisdiction during consultation.
