At RKM Homes, a Denver-based custom home builder, the door schedule on a blueprint is one of the most practical tools we use to turn design intent into reality. A door schedule is a consolidated table on the architectural drawings that specifies every door in the house by reference number and location, making it easy for the builder, framers, finish carpenters and suppliers to know exactly what to order and how each opening should be prepared on site. For custom homes built on a client’s lot, where site conditions, timing and coordination with trades matter, a clear door schedule reduces errors, avoids costly delays, and ensures the finished home matches the client’s selections.
A typical door schedule lists more than just a size and a name. Standard entries include a door mark or number that corresponds to plan callouts, clear and rough opening dimensions, door leaf size and thickness, handing/swing, material and core type (solid, hollow, insulated), finish and paint code, frame type and material, threshold and sill details, glazing type and size, transom or sidelight references, quantity, and manufacturer/model where specified. Critical performance and code attributes are also noted: fire rating, acoustic (STC) value, U-factor or insulation level for exterior units, and ADA compliance or egress specifics. The schedule will also point to associated documentation such as hardware sets, frame schedules, elevations, and installation notes, so everyone knows if a door requires a specific lockset, closer, astragal, or trim profile.
On our projects we use the door schedule as a coordination hub: we review it with clients during finish selections so style, glass pattern and hardware match room-by-room; we confirm rough openings during framing and before ordering to account for site conditions; and we use it to sequence deliveries and installations to meet weather protection and inspection requirements. For Denver’s climate and local code expectations, that often means specifying appropriate thresholds, thermal breaks, and weatherstripping for exterior doors and confirming required fire separations for attached garages or multi-family portions. A precise door schedule saves time, controls cost, and helps deliver the clean, functional results our clients expect when we design and build on their lot.
How do door tags on a blueprint show which door goes where?
On a blueprint you’ll see small door tags — typically a letter/number like D1, D2 or D3A — placed at each doorway on the floor plan. Those same tags are listed as rows in the door schedule, and the schedule will include the plan or elevation sheet references that tie that row back to specific drawing details. As a builder I always tell homeowners to find the tag on the plan first, then read across the schedule row to confirm which location that specific entry controls; the tag is the cross-reference that prevents confusion between similar openings.
Door tags also tell you when multiple openings are intended to be identical. If three bedroom closet doors are all labeled D4, that means they’re the same model, finish and trim detail (and therefore ordered together). If you want one of those doors to be upgraded or moved, request a new tag so the schedule and shop orders reflect the change; leaving identical tags in place is how mistakes happen on site. Tags will also include sheet-callouts — for example “see interior elevation 2/A6” — so you can check neighboring drawings that clarify appearance or trim for that specific tag.
Practical homeowner steps: bring a marked set of plans to site visits and match each physical opening to its tag on the drawing, or put temporary stickers with the tag number on the actual door frames so trades know which door to install. Check the door count in the schedule against the actual plan and the site to catch missing or extra tags before doors are ordered. Finally, always confirm you’re working from the latest revision — door tags and their references may shift as walls move, and I’ll reissue updated tags and schedules whenever we change a layout so your selections and the contractor orders stay synchronized.
What door sizes and required rough openings (width, height, thickness) should a door schedule list on a blueprint?
On a blueprint door schedule I always call out both the finished door slab size and the required rough opening so the framer, door supplier, and installer are all working from the same numbers. The schedule should show slab width and height (for example 3′-0″ x 6′-8″), the rough opening dimensions (stud-to-stud), and whether the width measurement is the nominal slab size or the clear opening at 90°. That distinction matters because a “3‑0″ door does not give you a 36″ clear opening once the jamb and stops are in place, and accessibility rules care about clear opening, not nominal slab size.
Be practical about the typical allowances you’ll see: most exterior doors are 1‑3/4″ thick and most interior doors are 1‑3/8″, and jamb depths are called out to match wall construction (4‑9/16″ for a 2×4 wall with drywall, 6‑9/16″ for a 2×6). For rough openings I plan for roughly 2″ extra in width and 2″–2½” extra in height beyond the slab size to allow for shims, the frame, and threshold or floor buildup — the schedule should state the exact allowance the builder expects. Special doors (oversized, sliding, pocket, or fire-rated) will have different rough‑opening requirements and those should be explicitly indicated in the schedule.
A homeowner can use the door schedule to avoid ordering mistakes: verify the schedule’s listed rough opening against the framing before you order prehung units, confirm whether the measurements are slab, jamb, or clear‑opening, and check that the jamb depth matches the wall thickness plus finish. Also coordinate flooring and threshold details with the architect or builder—if you change from carpet to tile, the necessary rough opening height and sill configuration can change, so get the final floor buildup and manufacturer rough‑opening requirements confirmed in writing on the schedule before fabrication.
What door types, materials, finishes, glazing, and fire or sound ratings are shown on a door schedule?
A door schedule will name the specific door type and the construction/material so you know exactly what to expect at delivery and installation — for example, “prehung oak 2‑panel solid core,” “fiberglass insulated exterior,” or “slab hollow‑core interior.” We include the finish designation (paint grade, stain grade, factory finish) and any factory vs. field finishing notes so you can plan color choices and maintenance; this prevents surprises like receiving a paint‑ready door when you expected a factory‑primed, finished unit. Practical tip: review the schedule for the exact make/model or manufacturer code so you can request samples and confirm grain, durability, and warranty before ordering.
Glazing details are listed in the schedule with the lite configuration (full lite, half lite, sidelights), glazing type (tempered, laminated, insulated IGU), and any performance coatings (low‑E, solar control) or obscuring patterns for privacy. For exterior doors the schedule will often note U‑value or NFRC data and whether glass is impact‑rated — information that affects energy costs and code compliance; for interior doors it will call out safety glazing where required (bathrooms, closets adjacent to showers, doors adjacent to stairs). As your builder, we make sure the schedule specifies whether glass is operable or fixed, the thickness and whether muntins are simulated or true divided lites so the delivered door matches your design and daylight/privacy expectations.
Fire and sound ratings are explicitly noted so each door meets the code and functional needs of the house — you’ll see fire‑label times (20, 45, 60, 90 minutes) next to doors that separate garage, stair enclosures, or rated corridors, and STC (sound transmission class) targets for walls/doors around media rooms, home offices, or master suites. These entries also tie to required frames, seals, and hardware (self‑closing hinges, rated seals) that are necessary for the rating to be effective; one common homeowner mistake is assuming a fire‑rated slab alone is sufficient when the frame and hardware must also be listed and installed to retain the rating. Before final selections we recommend checking the schedule against your permit requirements and your priorities — if quiet rooms or strict code separations matter, ask us to raise the STC target or confirm the labelled assemblies shown on the schedule.
What door hardware, lock types, handing, keying, and accessibility/egress details will a door schedule show on my blueprint?
A door schedule will call out each door’s hardware set by a short code that links to a hardware legend: you’ll see whether the door gets a passage knob, a privacy latch, an exterior lockset with deadbolt, a mortise lock, or an electronic smart lock. The schedule also shows handing (for example “LH inswing” or “RH outswing”), the backset and strike locations, and if a closer, kick plate, or threshold is required. As a builder I make sure these codes tell procurement exactly what to order — finishes, functions (privacy vs. keyed entry), and whether the lock is mechanical or needs power/wiring for a keypad or electronic strike.
Accessibility and egress requirements are explicitly noted because they affect hardware choices and installation details. Expect to see lever handles called out instead of knobs where ADA-style operation is required, and notes for minimum clearances, threshold heights, and reduced opening force on doors that serve accessible routes. For egress doors the schedule will specify exit devices or panic hardware, self-closing/positive latching for fire-rated doors, and any required delayed egress or emergency release features so the door meets building and life-safety codes.
Practical steps for homeowners: review the hardware legend early and decide if you want keyed-alike exterior locks, a master key system, or separate keys for each unit before items are ordered, and confirm handing with site mockups — changing swing after installation is costly. If you plan smart locks, ask us to note wiring or power needs in the schedule so electricians are coordinated. Finally, verify finishes and strike plate details on the schedule so thresholds, weather seals, and security features match your expectations for durability and accessibility.
Frame/jamb details, thresholds, trim, clearances, and installation notes
What specific frame and jamb details, thresholds, trim profiles, clearances, and installation notes will the door schedule call out on the blueprint? From a builder’s point of view the door schedule should identify the jamb depth (so the frame fits your finished wall), jamb material (wood, metal, or composite), whether the jamb is prefinished or field-finished, and any required jamb extensions or plaster guards for thick wall assemblies. It will also note casing/profile names so the millwork matches other trim in the house, and whether returns or rosettes are required at the head and jamb. For homeowners this means you can confirm the visible trim style and finish early, and know if the frame will arrive ready to paint or if staining and final fitting are part of the install.
What threshold and clearance details should I check to avoid problems with flooring and weatherproofing? The schedule typically specifies threshold type (low-profile, raised, thermal break, or storm threshold), whether a sill pan or back dam is required at exterior entries, and the required clearance under the door for finished flooring plus sweeps. Those notes tell you whether the door will be trimmed on-site for carpet, tile or hardwood and whether a recessed sill or transition will be provided. As the owner, confirm the finished floor thickness with your builder so the threshold height and door bottom gap are set correctly — this avoids sticking doors, oversized gaps, or awkward transitions between rooms.
What installation notes and tolerances will the blueprint include that I should verify during construction? Expect to see shim locations and fastening schedules (where to anchor into framing), required sealants or gaskets, head flashing or jamb flashing instructions for exterior doors, and any special straightness or plumb tolerances the manufacturer requires for warranty compliance. I always recommend homeowners ask to see those installation notes before drywall and flooring are finished so we can accommodate casing returns, hidden jamb extensions, and final paint/stain sequences; having those items spelled out in the schedule prevents callbacks for trim rehanging, threshold adjustments, or water intrusion fixes after occupancy.
