Common Questions

Frequently Asked Questions

Quick answers to the most common questions about our permit design services.

Do you prepare drawings for permit submission?
Yes. We can prepare coordinated permit packages that may include architectural plans, elevations, sections, site plan information, foundation plans, wall framing plans, roof framing plans, structural details, MEP layouts, structural calculations, seismic design notes, and plan check revision responses. Final acceptance depends on the local building department and project scope.
Can you help with ADU and garage conversion plans?
Yes. We prepare detached and attached ADU drawings for permit review, including floor plans, elevations, sections, foundation plans, framing plans, MEP layouts, structural details, and calculations where required. We also prepare garage conversion drawings showing the proposed living space, new walls, door and window changes, insulation notes, and MEP layouts.
Do you provide structural calculations?
Yes. We prepare structural calculations for residential projects, including beam sizing, column sizing, roof framing checks, floor framing checks, foundation checks, steel member design, timber member design, wind load checks, seismic design checks, and load path verification.
Can you revise drawings after city comments?
Yes. If your permit application has been reviewed and you received plan check comments, you can upload the correction letter. We can revise the drawings, update calculations, address missing details, and prepare response notes for resubmission.
Do you design foundations and framing?
Yes. We prepare foundation layouts, footing plans, slab plans, pier layouts, stem wall details, reinforcement notes, anchor bolt notes, holdown notes, and foundation calculations where required. We also prepare framing layouts showing studs, posts, beams, headers, rafters, joists, trusses, roof slopes, ridge members, bearing points, and structural support details.
Can you prepare MEP layouts?
Yes. We prepare basic residential mechanical, electrical, and plumbing layouts for permit coordination. This may include lighting layouts, outlet plans, plumbing fixture layouts, drain and water routing notes, HVAC notes, ventilation notes, and equipment locations — all coordinated with the architectural drawings.
What information do I need to start?
We can start from a rough sketch, hand drawing, photos, old plans, property information, or a basic written description. Clear dimensions, site photos, and project location help us prepare a more accurate scope and quote.
Can you help with removing a load-bearing wall?
Yes. If you are removing a load-bearing wall or modifying an existing structure, we can review the layout, identify support requirements, size replacement beams or posts, and prepare structural drawings and calculations for permit review.
