Local Intelligence
What Concord Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Concord — Community Development Department will not accept a permit application without them. Concord's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Concord does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Concord who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,840/month.
Permit Process & Fees
Community Development Department permit fees for this project type typically range from $3,500 to $12,000 depending on project valuation and scope. Plan check runs approximately 8 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Community Development Department as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Community Development Department ↗Construction Cost Context
Concord's adu / renovation construction costs run $315–$490 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Concord
Concord's Community Development Department will run your address through the ASCE Hazard Tool using a default soil classification, and because that default assumes worse soil than many lots actually have, a lot of homeowners get bumped into Seismic Design Category D (or even E) structural requirements that add engineering costs and redesign time nobody budgeted for. If your contractor doesn't push back and request a site-specific soil study early, you can end up over-engineering the foundation and paying for it. Also worth knowing: Concord won't let you rent the ADU short-term, so if your financing plan leaned on Airbnb income to pencil out the project, that math needs to change before you break ground.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Concord submittals, that $450/sqft figure and the 8-week plan check window read like state-level averages rather than what I see on the ground here, so I'd treat both as a starting point and get actual bids from local contractors plus a direct call to Concord's Community Development Department before penciling out your budget or schedule. Even with a clean 8-week estimate, I've watched plenty of first-time drawing sets bounce back for corrections, so build in a cushion rather than banking on that timeline holding."
Market Context
Concord has a median home value of $680,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in Concord with the strongest renovation and resale value potential include Cowell Terrace, Shadelands, Vista Diablo/Wilshire Estates, The Highlands, Crawford Village. Large single-family lots and proximity to Concord BART make it ideal for detached ADUs.
Permit Process
Permit applications are reviewed by the Community Development Department, with a plan check timeline of approximately 8 weeks. Permit fees in Concord range from $3,500 to $12,000 depending on project scope. Design review: Yes - for non-exempt ADUs (citywide) via Concord's Design & Site Review process.
Concord falls within Seismic Design Category Seismic Design Category (A–F): site-specific. Per City of Concord guidance use the ASCE Hazard Tool with default Site Soil Class = 'Default' (effectively conservative for C/CD/D) and then determine SDC per ASCE 7 / 2025 CBC; many Concord addresses will be SDC D (some may be E)., which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Concord Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Concord? +
You need accurate floor plans for: permit applications (required by Concord's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Concord? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Concord's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Concord? +
Our floor plan drafting packages for Concord start at $997 for a standard residential home. This includes measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my Concord home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Concord neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Concord building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Concord? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Concord. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Concord? +
In Concord, where median home values are around $680,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Concord? +
Yes — Concord's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Concord? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Concord homes built before the 1990s.
