Section 65.304 of the Orlando Land Development Code and the Florida Building Code (FBC) 8th Edition (2023) precisely regulate minor and major encroachments into required residential setbacks across Orlando’s R-1 and R-2 zoning districts. Projections as varied as HVAC condensing units, eaves, bay windows, steps, porches, generator pads, and utility structures are permitted to extend into minimum yard setbacks if drawn, dimensioned, and annotated in strict compliance with local code and the City’s plan review protocols. Every encroachment call-out, section detail, and screening note must be backed by reference to code sections and precise measured data to survive close scrutiny by Orlando Planning, Zoning, and Permitting reviewers.

Code-Compliant Dimensioning and Annotation of Minor Encroachments on Orlando Residential Site Plans

Allowances for Projections: Interpreting LDC 65.304 and FBC 8th Edition (2023)

Orlando LDC Section 65.304 is the governing ordinance for permitted minor encroachments. For residential properties, the code explicitly states the maximum allowable projections into side and rear setbacks for equipment and features:

  • HVAC Units: May project up to 24" (two feet) into side or rear setbacks (LDC 65.304(f)).
  • Window Sills and Eaves: May encroach up to 12" (one foot) beyond the main wall face (LDC 65.304(d)).
  • Steps: Front yard steps (and stoops/porches) often may project up to three feet into the required front setback (LDC 65.304(c)).

Additional allowances and clarifications are provided by the Florida Building Code 2023, which overlays material, installation, and accessibility requirements.

Dimensioning and Drawing Sheet Standards

  • Primary Structure vs Encroaching Projection: Primary building corners and footprint must be dimensioned to nearest property lines with solid dimension lines. Encroaching elements (e.g., HVAC pad, eaves) require separate chained dimensions from property line to outermost surface of the encroaching feature. Example:
    • “4.0’ from side property line to foundation wall; 2.0’ from side property line to HVAC pad (per LDC 65.304(f))”
  • Leader Lines and Drawing Notes: Encroachments must be directly linked to their dimensions with leader lines. Each leader should terminate with a call-out note stating: “Eave projects 12" into side setback per LDC 65.304(d)” or “Condensing unit: 24" max encroachment per LDC 65.304(f)”.
  • Projection Limits on Sheet:
    • Use dashed lines to delineate the full extent of the allowable projection zone as defined by code, parallel to the setback line.
    • Solid lines for the actual encroaching element allow plan reviewers to easily confirm no over-projection.
  • Typical Orlando Planning & Zoning Redlines:
    • “Dimension from property line to HVAC unit required”
    • “Missing code reference for eave projection”
    • “Projection encroaches setback beyond LDC 65.304 allowance-revise dimension”

Clarifying Compliance on Plan-Set Sheets

  • Every permitted encroachment must cite the specific code section. Placing this on the drawing itself (“per Orlando LDC 65.304(f)”) is standard practice in Orlando for plan review clarity.
  • Provide an enlarged plan detail or inset for any encroached element within five feet of a property line. Add the shaded or hatched setback zone, measured encroachment, and regulatory call-out all in one detail.
  • For HVAC units, confirm and note compliance with FBC Mechanical (minimum clearances for service area, FBC R303.4, M1305.1.3).
  • Confirm that all annotations, especially for elements like steps, eaves, or mechanical pads, specify “max” or “actual” encroachment, as over-projection is a top cause of resubmittal.

Enlarged Details and Material/Spec Notations

  • Enlarged Detail Example:
    • “PLAN DETAIL - TYP. SIDE SETBACK”: Dashed property line, solid wall face, chained dimensions for (a) wall to property, (b) eave to property; annotated with “Eave, 12” max projection per LDC 65.304(d).”
  • Spec Notes:
    • HVAC platforms: “Concrete pad, 2'x3', 3.5" min thickness, steel troweled finish. See FBC M1305.1.4 for pad requirements.”
    • Eave construction: “2x8 rafters @ 24” o.c. with drip edge, aluminum soffit, detail per FBC 2304.9.4.”

Detailing Architectural Projections: Eaves, Chimneys, Bay Windows, and the Limits of Encroachment

Reading the Allowances: LDC 65.304(d), FBC 8th Edition (2023), and R-1/R-2 Zoning

For elements like eaves, bay windows, cornices, and chimneys that exceed typical envelope limits, both code and City convention require drawing sheet clarity. Orlando’s LDC 65.304(d) and FBC (various chapters) set maximum permitted encroachments, and require drafters to differentiate between “projection beyond face of wall” versus “projection into setback.”

  • Eaves and Cornices: Max 12” projection into required setback per LDC 65.304(d); specific zones and limits are traceable on every plan review markup.
  • Bay Windows: Typically permitted to project up to 4 feet into required front setback but cannot contain habitable floor area or be wider than one-third the building elevation length abutting the yard (verify per LDC and site context).
  • Chimneys: Can project per FBC Ch. 10 and Orlando LDC, usually not more than 2 feet into required setbacks and only for the full height of the chimney mass not exceeding 8 feet in width.

Drawing Strategies for Orlando Plan Review

  • Plan View Conventions: Projections to be shown with dashed lines (“eave overhang (12” max, dashed)”), with legend describing dashes for encroachment limits and solid lines for wall planes.
  • Section Details: Every significant projection (especially bay window or chimney) should have a keyed section showing the full height and depth of encroachment relative to grade, property lines, and setback envelopes.
    • Section call-outs reference sheet and detail: “Section 2/A3.1: Bay Window Setback Encroachment-4.0’ max per LDC 65.304(c)”
  • Notes Differentiating Projection Types:
    • Annotate on related elevations or plans: “Projection measured from face of principal wall; overhang does not exceed allowed encroachment into [front/side/rear] setback.”

R-1 and R-2 District Specificities: Plan Reviewer Expectations

  • In R-1 (Single Family Residential) and R-2 (Two Family Residential) zones, the setback envelopes and permitted encroachments are identical in principle, but zoning overlays or local amendments may modify maximum allowed projections-a note on every site plan: “Setbacks and projections per LDC 65.304 and as modified by R-1/R-2 district overlay, see zoning table.”
  • Plan reviewers routinely cloud or redline:
    • “Projection shown as habitable space-bay must be non-habitable, clarify with section”
    • “Eave exceeds 12” into setback-adjust to code max or dimension actual”
    • “Wall projection incorrectly dimensioned, show from property line to outermost point”

Sample Call-Outs and Sheet Annotations

  • Eave Call-Out: “Dashed eave projection line (max 12” per LDC 65.304(d)).” Measurement arrow from property line to dashed line, value dimensioned.
  • Bay Window Detail: “Projection: 4’-0” max beyond wall plane into front setback, non-habitable, windows only-per LDC 65.304(c). Section 4/A5.2 clarifies massing.”
  • Chimney/Flue Note: “Chimney projection: 2’ max encroachment, width <8’ (see FBC 1003.9; LDC 65.304(d)).”

Dimensions, material specs, and code citations must appear both in the plan’s schedule/note column and within each keyed detail box. Omission of clear projection distinction (‘beyond wall face’ vs. ‘into setback’) results in predictable redlines.

Site Plan Call-Outs and Notes for Specific Mechanical and Utility Encroachments in Orlando

Mechanical Equipment: Placement, Dimensioning, and Screening

Exterior mechanical and utility encroachments-such as AC condensers, generators, meter banks, and transformer pads-are governed by Orlando’s LDC, OUC requirements, and the FBC Mechanical code. Per Section 58.982(a):

  • AC units and generators: No less than 1' from side lot line, 5' from the rear, only on one side of principal structure; never between the principal façade and street unless below grade and ≥15' from front/side lines.
  • Mechanical equipment not within 10' behind principal façade unless below grade and 15'+ from street/side.
  • Equipment must be screened from ground-level view by opaque fence, wall, or vegetation (minimum 1’ from equipment; must be at least as tall as equipment).

Utility Equipment: Easement, Pad, and Access Considerations

  • OUC transformer pads and meter banks must be outside public ROW but within servient easement entirely on owner’s property. Reference Orlando Utilities Commission Engineering Standards Manual, which stipulates “All commercial meters installed above ground; owner responsible for pad, conduit, and meter base to OUC standards; OUC inspection required.”
  • Call-out required: “Transformer pad (per OUC ESM Fig 4.2.1A); pad located within granted utility easement. Contractor to coordinate with OUC inspector for final location and access.”

Dimension and Annotation Techniques

  • Dimension all mechanical/utility pads from property lines, structures, and adjoining encroachments. For example:
    • “Generator 5.2’ from rear property line (min 5’ per LDC 58.982(a)(5)), pad 8” above grade.”
    • “Meter bank, 10’ from side property line, within 12’ OUC easement (see Sheet C1.1 for easement boundary).”
  • Include noise compliance notations: “Outdoor mechanical to comply with noise limits (see Chart 1, Ch. 42 Orlando Code).”
  • Screening details:
    • Plan symbols: Fence line (bold dashed), shrubs (hatch or crosshatch), labeled: “Screening: 6’ PVC privacy fence, min 1’ from condenser, height matches unit.”
    • Sect. or 3D detail: “Screen wall (stucco), min. height 4’-6”, color/finish to match main building.”

Typical Redlines and Plan-Reviewer Expectations

  • “Mechanical equipment too close to property line-revise to minimum 1’ (side)/5’ (rear), or provide code basis.”
  • “Provide screening detail and material call-out per LDC 58.982(a).”
  • “Transformer pad location conflicts with OUC easement-update final survey and utility sheet.”
  • “Submit noise compliance documentation or clarify ambient impact at property line.”

Managing Permitted Porch and Step Encroachments with Integrated Accessibility (ADA/FBC) Detailing

Porch, Stoop, Step, and Ramp Encroachments: Allowances and Limits

Porches and stairs are fundamental to entry design, and their encroachment is regulated by both LDC (Section 68.304(c)) and the FBC Accessibility code:

  • Porches/unenclosed awnings/balconies: May project 6' into required front setback.
  • Bay windows: Max 4' into required front setback, width limits apply.
  • Front steps: Typically 3' beyond front setback in most R districts.

Accessibility and FBC Compliance: Drawing Requirements

  • Ramps: Max slope 1:12 (8.33%), min clear width 36”, landings min 60” (level, <1:48 slope). Handrails (if rise >6”) at 34-38” above ramp surface; continuous on both sides, returns at ends.
  • Stairs: Riser height 4-7”; tread depth min 11”; handrails on both sides at 34-38”; nosings max 1.5” projection, ≤0.5” curvature radius. All per FBC Accessibility Ch. 4 and Ch. 5.
  • Landings: Level, min 60” square (length and width), max 1:48 slope, at top and bottom of each ramp or stair.

Detailing Grade Changes, Projections, and Materials

  • Dimension All Projections: Chain dimensions from the property line to wall face, stoop edge, porch edge, and/or ramp terminus.
    Ex: “Porch-Setback line to face of porch: 4’-8”; Porch edge to property line: 2’-2” (not to exceed 6’-0” total projection per LDC 68.304(c)).”
  • Indicate Grade Elevations: Existing/proposed grade levels must be dimensioned on section and site plans (±0.00 datum), with slope call-outs for any approach ramp.
    Note: “Proposed entry ramp: Elev. 0.00 at landing, ramp slopes at 1:12 to drive (Elev. -0.50’).”
  • Material Call-Outs: Indicate non-slip treads for exterior stairs/ramps, corrosion-resistant handrails (e.g., “Galv. steel, powder coat finish, 1.5” dia.”), and handrail bracket details.
    Ex: “Stair handrail: 1.5” dia. galv. tube, ¼” wall, 1.5” clearance to adjacent surface, mount at 36” AFF, returns to post/wall.”

Common Redlines in Orlando Review

  • “Ramp slope exceeds 1:12-revise for compliance with FBC Accessibility 405.2.”
  • “Landing insufficient-provide 5’x5’ min. at ramp terminus and door swing.”
  • “Stair handrails must be continuous both sides, 34-38” above nosing.”
  • “Stoop encroachment exceeds limit-dimensions must not pass 6’-0” into front setback.”

Sheet Conventions for Accessibility and Encroachment

  • Key section through porch/ramp/sidewalk with detail call-outs (“Section 1/A2.2: Entry Ramp and Porch Plan/Section”); cross-reference sheet in site plan notes.
  • Code references directly onto site plans, ex: “Entry ramp per FBC Accessibility 405; porch encroachment per Orlando LDC 68.304(c).”
  • Enlarged landing detail: Full landing area, show door swing, handrail, ramp edge-all dimensioned; indicate slope direction and value.

Navigating Orlando's Plan Review Comments and Revisions for Setback Encroachment Discrepancies

Addressing the Common Redlines: Techniques and Code Citations

  • Review comment clouds and revision deltas are added to all revised sheets at each resubmittal round. List code section and reviewer note alongside each cloud, such as: “Δ1 - Corrected eave projection per review comment (‘Eave exceeds allowed projection’), now 12” max into setback (LDC 65.304(d)).”
  • Every dimension must match code maximums, and any code section cited in the reviewer comment must appear next to your drawing annotation or leader note.
  • Use bold dimensions for revised values and re-check both graphic (plan) and numeric (schedule) references for consistency. Example plan sheet revision:
    • “HVAC unit relocated 1.5’ from side property line, screening clarified per LDC 58.982(a), see revised Detail 3/A4.1.”

Methods for Making and Communicating Revisions

  • Each resubmittal must include a response letter addressing all outstanding reviewer comments point by point, indicating which sheet(s) the correction appears on and directly quoting any plan note that clarifies the issue.
  • All plan changes must be revision-clouded, with delta tags and references to the review cycle (e.g., “Δ2-5/24/2024-Corrected projection dimensioning per plan review comment #7.”)
  • Title block revision logs should cross-reference drawing deltas (“Δ2: see Plan Review Comment #7, Sheet A1.2, Dim. Eave to setback.”)

Common Plan Reviewer Comments and Typical Fixes

  • “Verify encroachment dimensions per LDC 65.304”-Solution: Add explicit dimension to projection, include code note at leader annotation.
  • “Eaves exceed allowed projection”-Solution: Adjust eave to 12” max, update plan and section views, annotate adjusted dimension, and reference LDC 65.304(d).
  • “HVAC unit requires screening”-Solution: Add or clarify call-out for fence/vegetation/screen wall, provide enlarged elevation or 3D detail, include material specification and height.

Digital Submission and Pre-Submittal Coordination

  • Upload all revised sheets with correct file names indicating the review round. In Orlando’s digital portal, flag each changed sheet and use the comment field to describe the correction (“Sheet A1.2 updated for eave dimension and note per LDC 65.304(d)”).
  • If in doubt, consult with the City's Permitting Services (orlando.gov) or request a pre-submission meeting for complex setback encroachment situations.
  • Failure to transparently document corrections or repeat a previous error in resubmission guarantees another cycle of review comments.

Integrating Setback Encroachment Details into Drawings for Approval and Construction

Consistent, granular dimensioning from property lines to every encroaching feature, robust code call-outs (“per LDC 65.304,” “per FBC M1305.1.3”), and detailed sheet notes (especially for mechanical pads, eaves, steps, porches, or utility equipment) are essential for traversing the Orlando plan review gauntlet without significant delay. Include both plan and section visuals, material and screening specifications, accurate setback and projection data, and fortify them with code citations in every instance. All corrections get clouded and logged per City protocol.

Failure points include omitting code sections, missing dimensions from property line to the outermost encroachment point, not graphically distinguishing “face of wall” from “projection,” and neglecting screening/utility access graphics for mechanical encroachments. Each of these is a prelude to resubmittal redlines.

Mastery is exhibited not only in the precision of drawing output but in the clarity and traceability of code compliance, aiding Orlando's plan reviewers and builders alike. With these standards, residential drafter teams assure streamlined approvals, minimize client headaches, and provide a frictionless path from permit set to final inspection, no matter how tight the setbacks or how complex the encroachments.
