The building codes for Sedona, Arizona, set specific design rules as well as safety and permitting requirements. For single-family homes over 1,000 square feet but under 2,000 square feet, plans must show at least two visual building masses of differing heights and planes; at 2,000 square feet or greater, they must show at least three. Each mass must be at least 100 square feet.
A custom home is shaped by more than its floor plan. Site orientation, building form, applicable county policies, and review by the relevant departments can all affect how a project moves from concept to permit.
This guide explains key building codes for Sedona Arizona and requirements to understand before developing plans, including building form, street orientation, plan review, permitting, department coordination, and the codes Coconino County applies. Requirements can also vary with building use, size, and location.
Understanding the applicable rules helps you approach design and approvals with greater confidence and make informed decisions as your Sedona project takes shape.
Building massing requirements by use and floor area
A visual building mass is a distinct portion of a structure defined by its height and wall planes. In Sedona, single-family homes over 1,000 square feet but under 2,000 square feet need at least two such masses. Homes with 2,000 square feet or more need at least three. Each mass must cover at least 100 square feet.
Gross floor area is the combined floor area used to determine which massing threshold applies. Manufactured homes with 1,500 square feet or more require at least two visual masses. Commercial and public or semi-public buildings with 2,500 square feet or more require at least three. These thresholds make building use and total floor area central to early design decisions.
For context on permits and code compliance, watch this video:
A building mass is the overall form perceived as one section of a building. For commercial and public or semi-public projects, the largest single mass may occupy no more than 60 percent of the total footprint. An unrelieved exterior wall plane, meaning a broad wall without visual breaks, may not exceed 800 square feet unless an exception is approved.
Multifamily and lodging projects have additional form limits. A multifamily building needs at least one façade articulation element for every 30 feet of façade. A qualifying projection, recession, or reveal must change the wall plane by at least 24 inches. Multifamily residential and lodging buildings may not exceed 200 feet in length, regardless of height.
Separate structures can count as one massing unit when they sit close together. Structures on the same property with a maximum wall-to-wall separation of five feet are treated as one structure for massing purposes. For multistory buildings, each upper floor must have at least 10 percent less floor area than the floor immediately below it.
Properties in the Sedona Fire District must comply with its adopted 2018 Wildland and Urban Interface Codes, and fire suppression systems are required. For defensible-space planning, account for vegetation and emergency access alongside those fire-safety measures. The district adopted its 2024 International Fire Code and amendments on April 21, 2026; it became effective May 1, 2026, under Resolution #2026-01.
For hillside, steep-slope, floodplain, or environmentally sensitive sites, design must respond to the property’s conditions and applicable county criteria. Coconino County allows ASCE Hazard standards and/or County Design Criteria for snow load, wind speed, and seismic zone. Account for these factors in site and structural planning from the outset.
Construction plan review and permitting
Plan review checks proposed work against applicable building and fire requirements before construction. In Sedona, the reviewing jurisdiction depends on the property’s location and the agencies involved.
Applications, department reviews, and inspections are connected steps. Their sequence and requirements determine when construction can proceed.
Design Review and Landscape Requirements
Design review evaluates plans and exterior features against applicable local requirements. For new construction and exterior changes, an application may need to address building form, street-facing features, and landscaping. Requirements depend on the project and its location.
The Sedona Fire District coordinates development plan review with Coconino County, Yavapai County, and the City of Sedona because its boundaries overlap those jurisdictions. The Sedona Fire Marshal conducts concurrent plan reviews with Coconino County to assess code compliance. Additions and new construction within the fire district must go through permitting and review under its adopted fire code.
Submit the applications and materials required by district policies before work begins. This allows reviewing departments to assess the plans and relevant fire systems before construction proceeds.
Code Violations and Appeals
Code enforcement addresses construction that proceeds without required approvals or departs from applicable requirements. Building without a permit or failing to follow approved plans can lead to required corrections and further review.
The correction process and any penalties depend on the governing jurisdiction and the circumstances of the work. Appeals follow the jurisdiction’s formal review process, with the relevant decision and project documents helping frame the issue. For work in the Sedona Fire District, its adopted fire code and standards apply to new and existing buildings, remodels, improvements, and new subdivisions.
Before work begins, align construction with required permits and approvals. If a review identifies a conflict, resolve it through the responsible department’s process before continuing the affected work.
Permit Fees and Inspection Costs
Permit fees are charges associated with reviewing and issuing construction approvals. Coconino County’s newly adopted building permit fees take effect January 1, 2027.
Inspections assess permitted work at stages set by the applicable approval and code requirements. Schedule each inspection through the permitting jurisdiction’s process, using the project’s permit details and the stage ready for review. Required inspection points vary, so follow the approved documents.
Total project costs combine permit charges, required inspections, and construction expenses. For a useful estimate, separate these categories and account for project scope, applicable county fees, and any fire-system review. Coconino County will accept fully submitted applications designed to its previously adopted codes through December 31, 2026.
For help aligning a Sedona property decision with a future build, begin a project planning conversation.
Building department coordination
Building department coordination means aligning reviews by the authorities responsible for a property. In Sedona, the Sedona Fire District’s boundaries overlap the City of Sedona, Coconino County, and Yavapai County, so a project may involve multiple jurisdictions.
First identify the authorities reviewing the parcel and the proposed work. Then match the plans to each applicable code set and submit the required applications before work begins. This is important because the fire district requires submissions under its policies and standards before a project or event starts.
A code transition is the change from one adopted code edition to another. Coconino County’s newly adopted building codes took effect June 2, 2026. The county’s current residential code is the 2024 International Residential Code, and its current building code is the 2024 International Building Code. Its current International Mechanical Code and International Plumbing Code are also the 2024 editions.
Earlier code editions have a defined application window in Coconino County. The county accepts fully submitted permit applications designed to its previously adopted codes through December 31, 2026. Those earlier editions include the 2018 International Residential Code and the 2017 National Electrical Code. The transition provision is tied to fully submitted applications, not simply an early design or partial filing.
Fire code adoption is a separate track from the county’s building-code transition. The Sedona Fire District adopted the 2024 International Fire Code and its amendments on April 21, 2026. Under Resolution #2026-01, that fire code became effective May 1, 2026. Its adopted standards apply to new and existing buildings, remodels, improvements, and new subdivisions.
The district’s later amendment also matters for projects reviewed after its effective date. The Sedona Fire District’s 2024 International Fire Code, Second Amendments, are effective October 20, 2026. Resolution #2026-03 adopts revisions to those Second Amendments. Distinguish the original adoption and effective dates from this later amendment when organizing a project’s code references.
For a practical coordination sequence, keep the jurisdiction, code edition, and application status together:
- Identify whether Coconino County, Yavapai County, the City of Sedona, or the Sedona Fire District has a review role.
- Record the applicable code editions, including the county’s June 2, 2026 transition and fire-code amendments.
- Submit complete applications and required district materials before work begins.
- Keep each department’s comments and plan revisions aligned, so changes in one review set are reflected in the others.
An organized record helps distinguish county building-code requirements from fire-district standards. It also gives the project team a clear reference when a plan revision affects multiple reviewing jurisdictions.
County building policies
County and city policies add site, exterior, and accessory-use rules to construction codes. In Sedona, applicable requirements depend on the parcel, building type, and proposed work. These local policies complement the building codes for Sedona Arizona by addressing site design and exterior features.
Street orientation is a design rule for buildings near public access. In Sedona, buildings within 50 feet of a public or private street, right-of-way, or easement must orient their building masses toward the street. This requirement affects site planning before the building footprint is finalized.
Street-facing transparency means windows or doorways visible along a façade facing public space. The ground-floor level of each façade facing a public street or other public area must have at least 30 percent windows or doorways. Upper floors of each façade facing a public street must contain at least 15 percent windows, subject to the stated energy-code allowance.
Roofline variation breaks up a long, uninterrupted roof edge. No roofline along a building elevation may exceed 50 feet in length without a visual variation. Storefront-type glass walls also have a continuity limit: they may not extend in an unbroken façade for more than 20 feet.
Height transition is a design response where a new building rises beside an existing residential building. If a new building uses alternate height standards and exceeds the adjacent building’s height by 10 feet or more, it must use at least two listed height-transition techniques. A qualifying stepped-down portion must meet the existing neighboring building’s height along at least 50 percent of the new building’s length.
An accessory dwelling unit is a secondary residence on the same lot as a main building. Sedona permits one accessory dwelling unit per lot, and the unit must be smaller than either 750 square feet or 50 percent of the main building’s size. The rule ties the allowed unit size to the primary residence, so both measurements matter during planning.
Residential heating rules can shape equipment selection. Sedona prohibits wood fireplaces and stoves in new homes unless they meet EPA phase 2 standards. Coconino County also maintains focused policies for specialized construction:
- Earthen building construction is addressed by ordinance 2020-11.
- Greenhouses up to 400 square feet are covered by policy BD-2019-002.
- Accessory structures less than 200 square feet are covered by policy BD-2020-009.
These policies apply to distinct building types and project features. For example, a greenhouse plan should account for BD-2019-002, while a detached accessory structure below 200 square feet falls under BD-2020-009. Matching the project description to the relevant policy helps keep the design, application, and review materials consistent.
Before developing a site plan, identify whether the property falls under Sedona or Coconino County rules, then apply each relevant standard to the feature it governs. Building codes for Sedona Arizona interact with parcel-specific policies, so distinguish façade requirements from accessory-use rules when preparing plans.
What are Sedona's residential building requirements for structural design, energy efficiency, and safety?
Structural design establishes the criteria used to size and detail a home’s structure. Coconino County allows ASCE Hazard standards and/or Coconino County Design Criteria for snow load, wind speed, and seismic zone. Because these criteria address different site forces, clearly state the selected design basis in the plans.
For a Sedona home, structural planning starts by identifying the applicable design criteria and the conditions they address. Snow load, wind speed, and seismic zone each influence design decisions. Show the criteria in the plans and use those assumptions consistently in structural details and supporting documents.
Energy efficiency includes measures that limit unwanted air movement through a home’s exterior. Sedona requires new homes to be tested for air leakage under IRC N1102.4.1.2. This makes air-leakage testing part of the residential compliance path, not simply an optional performance upgrade.
Air leakage testing evaluates whether the completed home meets the applicable code requirement. Include the test in the project’s compliance planning, and coordinate it with the construction sequence and documentation. This connects the code provision to the finished home instead of leaving it as a late-stage paperwork task.
Wildland-urban interface requirements address building safety where structures meet areas exposed to wildfire conditions. The Sedona Fire District adopted the 2018 International Wildland Urban Interface Code on November 16, 2021, through Resolution No. 2021-05 and district amendments. The district, including Oak Creek Canyon, has adopted the 2018 Wildland and Urban Interface Codes.
Fire suppression is a separate safety requirement for buildings within the Sedona Fire District. The district requires fire suppression systems as well as compliance with its wildland and urban interface codes. Residential planning must account for both the applicable interface provisions and fire suppression; one does not replace the other.
For a residential plan set, organize these requirements as distinct review items:
- Structural criteria: identify whether the design uses ASCE Hazard standards and/or Coconino County Design Criteria for snow load, wind speed, and seismic zone.
- Air leakage: include the new-home test required under IRC N1102.4.1.2.
- Wildland interface: account for the district’s adopted 2018 code and amendments.
- Fire suppression: include the required system for construction within the Sedona Fire District.
Aligning these items early gives the design and construction teams a clear compliance checklist. For guidance connecting residential plans with a Sedona property, discuss your building plans.

Frequently Asked Questions
Which building codes has the City of Sedona, Arizona adopted, and what editions are in effect?
The applicable edition depends on which jurisdiction reviews the property. For county-reviewed projects, Coconino County’s current residential code is the 2024 International Residential Code, and its current building code is the 2024 International Building Code. Its mechanical and plumbing codes are also the 2024 editions. The Sedona Fire District separately uses its adopted fire code and amendments, so identify the parcel’s reviewing authorities before selecting code references.
Do building codes differ between Sedona city limits and unincorporated Yavapai or Coconino County?
Yes, requirements can differ based on the property’s jurisdiction and reviewing departments. Sedona’s boundaries and those of the Sedona Fire District do not form a single review area. The fire district coordinates with the City of Sedona, Yavapai County, and Coconino County. For a property near a boundary, establish which agencies review the parcel before relying on a code edition or local development standard.
What permits are required to build, remodel, add an accessory dwelling unit, or install a pool in Sedona?
Permit requirements depend on the work and the parcel’s jurisdiction. New construction and additions within the Sedona Fire District go through permitting and review; remodels and improvements must also follow the district’s adopted fire standards. Sedona allows one accessory dwelling unit per lot, subject to its size limit. For a pool or other improvement, determine the applicable review path from the property location and project scope before work begins.
What zoning, setbacks, height limits, and lot coverage rules apply to building in Sedona?
Standards depend on the parcel’s zoning and applicable development rules, so there is no single citywide setback or lot-coverage figure for every property. Review the zoning designation alongside the proposed building dimensions. For example, a height standard may trigger additional design measures when a new building rises substantially above an adjacent residence. Show the proposed footprint and its relationship to neighboring structures on the site plan.
How do I apply for a Sedona building permit, what documents are needed, and how long does review take?
Start by identifying the reviewing jurisdiction, then submit the required application materials before construction. A coordinated package can include the application, site plan, construction drawings, and relevant structural or fire-system information. The Sedona Fire Marshal conducts concurrent plan reviews with Coconino County. Review duration depends on application completeness, project complexity, and review comments; no single timeline applies to every Sedona project.
