ADU Rules in Broomfield: The Complete 2026 Homeowner’s Guide

At a Glance

A quick scan if you don’t have time for the full guide:

Broomfield is a Subject Jurisdiction under HB24-1152 (effective June 30, 2025). Local implementation through Ordinance No. 2265, adopted September 9, 2025, effective September 16, 2025.
ADUs are permitted on any lot zoned for a detached single-family dwelling. All three forms allowed: internal, attached, and detached.
Owner-occupancy is not required. You can rent both your primary dwelling and your ADU long-term to non-owners.
Size cap: 500 sq ft floor (allowed on any qualifying lot regardless of primary size). Above 500 sq ft, the ADU is capped at 50% of the principal dwelling’s footprint (excluding garage and porch) or 800 sq ft, whichever is less.
Setbacks: must meet the zone’s accessory-building setbacks, but never less than 5 ft from any property line. ADU cannot be placed in front of the primary dwelling.
Broomfield’s biggest cost advantage: ADUs tie into the primary dwelling’s water and sewer connections. No separate water tap, no separate sewer tap, no separate utility license. This saves $10K to $30K versus other Colorado markets.
Design: ADU must be clad in material similar to the principal dwelling. RVs, trailers, mobile homes, and shipping containers are prohibited. Manufactured, modular, and tiny homes are allowed if on proper foundation and clad to match.
Short-term rental of an ADU is constrained by Broomfield’s broader principal-residence-only STR rule. Long-term rental of an ADU is fully permitted.
Parking: none required UNLESS adjacent streets prohibit on-street parking AND the ADU is not in a Parking Reduction Area. When both conditions apply, three total off-street spaces are required (two for primary, one for ADU).
Declaration of Use must be recorded against the property title for detached ADUs before Certificate of Occupancy.

Why Broomfield’s ADU Rules Are Different

Three forces shape Broomfield’s regulatory framework, and reading them in order makes the rest of the rules easier to absorb.

First, shared utilities by default. Broomfield is the only major Colorado city we cover where ADUs simply tie into the primary dwelling’s existing water and sewer connections. No separate tap fees, no separate utility licenses, no Plant Investment Fees on a new ADU connection. This saves $10K to $30K versus Denver, where Denver Water charges a separate ADU System Development Charge, or Fort Collins, where Plant Investment Fees vary by water provider and jumped sharply in 2026.

Second, the cladding-and-design rule is specific. Broomfield requires ADUs to be “designed to be consistent with the design of the principal dwelling unit,” and on properties without specific design standards, the ADU must be clad in material similar to the principal structure. The city explicitly prohibits RVs, trailers, mobile homes, and shipping containers as ADUs. Manufactured, modular, and tiny homes are allowed if they are on a proper foundation and clad to match. This rule is more specific than most other Colorado cities, which use general “compatibility” language.

Third, parking is conditional. Unlike Denver, Boulder, Fort Collins, or Colorado Springs (all of which eliminated ADU parking entirely or kept narrow procedural requirements), Broomfield triggers parking only when two conditions both apply: the adjacent street prohibits on-street parking AND the ADU lot is not in a Parking Reduction Area. When both apply, three total spaces are required (two for primary, one for ADU). For most Broomfield lots, parking is not triggered.

The trade-off worth absorbing: Broomfield is structurally cheaper to build in than most major Colorado markets thanks to shared utilities, but requires more attention to design coordination (the cladding rule) and a Declaration of Use recording step that other cities don’t impose.

Can You Build an ADU on Your Broomfield Lot?

Most Broomfield single-family lots qualify.

Zone eligibility. Ord 2265 confirmed ADUs as a permitted accessory use on any lot zoned for a detached single-family dwelling. The map of where ADUs are allowed is essentially the map of residential Broomfield.

No minimum lot size. Ord 2265 did not impose an ADU-specific minimum lot size. Standard zone-district minimums still apply to the primary use.

What governs whether your specific lot can support a given ADU type and size:

Zone district (and the standard accessory-building setbacks for that zone)
Primary dwelling footprint (drives the 50% size cap calculation above the 500 sq ft floor)
Lot dimensions (ADU cannot be in front of the primary; setbacks ≥ 5 ft from all property lines)
Building separation requirements between the ADU and other on-lot structures
Whether you have municipal sewer or septic (septic users need Broomfield Health & Human Services sign-off)
Parking Reduction Area status of the lot + on-street parking availability on adjacent streets

Broomfield is plains/suburban; there is no Wildland Urban Interface overlay restricting ADU types in the city. Compared to Colorado Springs (WUI-O) or Fort Collins (Poudre Fire WUI in foothills), Broomfield is geographically simpler.

HB24-1152 + Ord 2265: The Two Laws That Apply

Broomfield’s ADU framework rests on two layers of law working in concert.

HB24-1152 (state law, effective June 30, 2025). Colorado’s state ADU law applies to Subject Jurisdictions, which includes Broomfield (within the DRCOG MPO). The law sets a floor for ADU permissiveness: every Subject Jurisdiction must allow at least one ADU on every lot that permits a single-unit detached dwelling, must process code-compliant ADU applications administratively, and cannot impose owner-occupancy mandates, ADU-specific minimum lot size restrictions, parking minimums (with narrow exceptions), or design standards more restrictive than those applied to the primary dwelling. HOAs lost the power to outright ban ADUs.

Ord 2265 (Broomfield ordinance). Adopted September 9, 2025; effective September 16, 2025. Ord 2265 is the most recent ADU ordinance among the five Colorado cities in this series. Key elements: ADUs permitted on any lot zoned for a detached single-family dwelling, all three forms allowed (internal, attached, detached), no owner-occupancy required, conditional parking, shared utilities by default (no separate water or sewer tap), and the cladding/design rule. Codified in Broomfield Municipal Code Title 17.

Practical takeaway: HB24-1152 sets the floor. Ord 2265 implemented the state baseline and layered three Broomfield-specific elements (shared utilities, cladding rule, conditional parking with the PRA test). Both are enforceable, with Ord 2265 controlling Broomfield-specific implementation. Our walks the state-law text.

Size, Setbacks, and Height

Size cap. Any ADU may be up to 500 sq ft on any qualifying lot, regardless of primary dwelling size — this is a hard floor that protects smaller lots from being effectively excluded. Above 500 sq ft, the ADU is capped at the lesser of 50% of the principal dwelling’s footprint (excluding garage, porch, or similar non-conditioned areas) OR 800 sq ft. Whichever is smaller controls.

Setbacks. ADUs must meet the underlying zone’s accessory-building setbacks, but never less than 5 ft from any property line. The ADU’s side setback cannot exceed the side setback that applies to the primary dwelling. The ADU cannot be placed in front of the primary structure. If the ADU is too close to the primary to satisfy building separation, it must meet principal-structure setbacks instead.

Max height. Broomfield’s published ADU FAQ does not state a specific maximum height in feet or stories. The applicable height tracks the zone’s standard accessory-structure maximum (typically 25 ft or 2 stories in most residential zones, but verify against your specific zone in Broomfield Municipal Code Title 17 before designing).

Lot coverage. Per the zone district’s standard. The ADU footprint counts against the zone’s overall lot coverage cap along with the primary structure and any other accessory buildings.

Maximum number of ADUs per lot: 1. Broomfield allows one ADU per qualifying lot. Multi-ADU configurations are not permitted under Ord 2265.

The Shared-Utility Advantage

Broomfield is the only major Colorado city we cover where ADUs share utilities with the primary dwelling by default. This is the single biggest cost differentiator versus the other four cities.

What it means. ADUs in Broomfield tie into the principal dwelling’s existing water and sewer connections. No separate water tap is installed. No separate sewer tap is installed. No separate water or sewer license is required.

Cost impact. Compared to Denver, where Denver Water charges a $2,055 to $3,030 ADU SDC on top of the city building permit, Broomfield saves you the SDC entirely. Compared to Fort Collins, where Plant Investment Fees vary by water provider and jumped sharply in 2026 (FCLWD’s 3/4″ residential tap PIF went from $17K to $27,175), Broomfield saves you the PIF entirely. The total utility-side savings range from $5K to $25K depending on which Colorado market you’re comparing against.

Septic exception. Properties on septic systems rather than municipal sewer require sign-off from Broomfield Health & Human Services to confirm the septic system can support the additional fixture load of the ADU. The HHS review is a procedural step but can add 2 to 4 weeks to your timeline if your septic system is older or near capacity.

What gets verified at permit submittal. Your building permit application confirms the shared-tap configuration. The city does not require Plant Investment Fee payment or a separate utility license. Most ADU projects in Broomfield see total municipal fees in the $3K to $8K range — among the lowest in Colorado.

The Cladding and Design Rule

Broomfield is specific about ADU design coordination in a way most other Colorado cities are not. Understanding this rule before design saves time on plan review.

The compatibility standard. Per Ord 2265, ADUs must be “designed to be consistent with the design of the principal dwelling unit.” This is a compatibility standard, not a strict matching mandate. The intent is visual coherence between the ADU and the primary structure as viewed from the street.

The cladding requirement (when no specific design standards apply). On lots that do not have property-specific design standards (no HOA covenant requirements, no historic overlay), the ADU must be clad in a material similar to the principal structure. If your primary home has stucco siding, the ADU should use stucco. If your primary has fiber-cement lap siding, the ADU should match. Brick-on-brick is the cleanest match; mixed claddings work if the primary has multiple materials already.

What is explicitly prohibited as an ADU. RVs, trailers, mobile homes, and shipping containers are all prohibited as ADUs in Broomfield. The city draws a clear line: an ADU must be a built structure, not a movable or temporary unit converted to occupancy.

What is explicitly allowed. Manufactured homes, modular homes, and tiny homes are permitted as ADUs IF they are on a proper permanent foundation AND clad in material consistent with the primary dwelling. A modular ADU craned onto a poured foundation with fiber-cement siding to match the primary is fully compliant. A factory-built tiny home on a chassis is not.

For the underlying type-choice analysis (detached vs attached vs interior), our walks the trade-offs between the three forms.

The Conditional Parking Rule

Most Colorado cities have eliminated ADU parking entirely. Broomfield kept a narrow exception that depends on two factors. Most lots won’t trigger it.

When parking is NOT required. No new parking is required for an ADU in Broomfield in most cases. The default rule is: zero additional off-street spaces needed.

When parking IS required (both conditions must apply). Three total off-street spaces are required (two for the primary dwelling, one for the ADU) only when BOTH of the following are true: (1) the adjacent street does not allow on-street parking, AND (2) the ADU is NOT located in a Parking Reduction Area (PRA).

What a PRA is. A Parking Reduction Area is a Broomfield-designated zone where the city has formally reduced parking requirements based on proximity to transit, walkability, or other planning criteria. Most central and transit-adjacent Broomfield lots fall in a PRA. Verify your lot’s PRA status with Broomfield Planning before assuming parking is or isn’t required.

Practical implication. For most Broomfield ADU projects, parking is not triggered. The condition that activates the parking requirement (no on-street parking adjacent + not in a PRA) is uncommon. But if both apply on your lot, factor in $10K to $30K for the parking pad construction.

Short-Term Rental Rules

Broomfield’s STR framework constrains ADU STR by attaching to the citywide STR-must-be-principal-residence rule, rather than imposing an ADU-specific prohibition.

Principal-residence-only STR. Broomfield’s overall STR licensing program (Broomfield Municipal Code Ch. 5-39, Ord 2072) requires that any short-term rental be on the host’s principal residence. This applies to STR on the primary dwelling, the ADU, or any other structure.

What this means for ADU owners. You can STR your ADU only if the property is your principal residence. If you live in the primary and STR the ADU, that’s permitted. If you do not live on the property, you cannot STR the ADU at all (you also cannot STR the primary dwelling under the same rule).

Licensing details. STR license application fee: $100. License term: 5 years. An annual affidavit certifying continued principal residency is required. STR licenses don’t transfer with property sale; the new owner must apply for a new license.

Long-term rental is fully permitted. ADU long-term rental (30+ days) has no owner-occupancy or principal-residence requirement. You can rent both your primary and your ADU long-term to non-owners without restriction. The principal-residence rule only governs STR.

Owner-Occupancy and HOAs

Owner-occupancy for long-term rental: NOT required. Ord 2265 eliminated the previous owner-occupancy requirement that some Broomfield homeowners assumed still applied. You can rent both your primary dwelling and your ADU long-term to non-owners. HB24-1152’s state preemption also applies.

Owner-occupancy for STR: still required indirectly. The STR license requires the property to be the host’s principal residence. So if your investment thesis is STR-driven, owner-occupancy is functionally required (covered in the STR section above). For long-term rental, no such requirement.

HOA carve-outs. Broomfield’s ADU FAQ explicitly directs homeowners to “contact your HOA before submitting a building permit.” HB24-1152 voids outright HOA bans on ADUs in Subject Jurisdictions, but HOAs retain authority to apply aesthetic standards consistent with primary-residence requirements. Common Broomfield HOA issues include exterior color, roof material, and design review for ADUs visible from common areas.

The codified preemption is at CRS 38-33.3-106.5.

The Permit Process: Step-by-Step

Five steps from idea to issued permit. Broomfield’s process is cleaner than some other Colorado cities because there is no separate land-use approval — just a building permit with ADU-specific documents attached.

1. Pre-application check. Optional but recommended. Confirm zone eligibility, PRA status (for parking), water/sewer service configuration, and any HOA covenant restrictions. Broomfield Planning can answer most pre-application questions by phone or email.

2. Submittal of Building Department General Permit Application + ADU Checklist + Declaration of Use. Three core documents required by Ord 2265. The ADU Checklist is a 2025 fillable form available on the Broomfield website. The Declaration of Use commits the size and location of the ADU; it gets recorded against the property title before Certificate of Occupancy (for detached ADUs).

3. Building review and plan corrections. Broomfield Building Division reviews structural, mechanical, electrical, plumbing, and energy code compliance. Plan corrections typical for first submittals.

4. Permit issuance and inspections. Once corrections are addressed and HHS sign-off is in place for septic properties, the building permit issues. Standard Broomfield inspection sequence follows.

5. Declaration of Use recorded; Certificate of Occupancy. For detached ADUs, the Declaration of Use is recorded with the Broomfield Clerk before CO is issued. This ties the ADU to the property in the public record and surfaces in any future title search.

Realistic timeline. 6 to 12 weeks from submittal to issued permit for typical projects. Broomfield’s published timeline is not specifically broken out for ADUs, but the building permit category in their standard schedule falls in this range.

What You Submit and the Inspection Sequence

Application document checklist:

Broomfield Building Department General Permit Application
ADU Checklist (2025 fillable form on broomfield.org)
Declaration of Use form (recorded before CO for detached ADUs)
Site plan with existing and proposed structures plus all setback dimensions
Floor plans for the ADU
Elevations (all four sides) with exterior materials and cladding details (to demonstrate the design-consistency rule)
Structural drawings (engineer-stamped where required)
Health and Human Services sign-off if on septic

Inspection sequence (standard Broomfield Building Division residential):

Footing inspection
Foundation inspection (before backfill)
Underground plumbing
Rough framing
Rough plumbing, electrical, mechanical (separate inspections)
Insulation inspection
Drywall inspection
Final building, plumbing, electrical, mechanical (separate)
Declaration of Use recording (detached ADUs only)
Certificate of Occupancy

Appeals and Variances

If your code-compliant ADU application gets denied or if you need a variance, you have options.

Building and Zoning Board of Adjustment. Broomfield’s Board of Adjustment hears variance requests and zoning interpretations under Title 17 of the Municipal Code. A variance is appropriate when your project doesn’t strictly comply with a code provision but warrants relief due to hardship or unique lot conditions.

District Court appeals. Final administrative decisions are subject to judicial review through Colorado Rule of Civil Procedure 106(a)(4).

Most code-compliant ADU applications don’t trigger appeals. The structure exists primarily for lot-by-lot variance requests where strict compliance creates a hardship.

What the table shows. Broomfield has the lowest utility-side cost (no separate water or sewer tap), the most recent ordinance (Ord 2265 effective September 16, 2025), and the most specific design rule (cladding compatibility plus the Declaration of Use recording). The Broomfield-unique advantage is the shared-utility default, which can save $5K to $25K versus the other four cities. The Broomfield-unique constraint is the design-consistency rule, which requires more attention to architectural coordination than most Colorado markets.

FAQ

How much does it cost to permit an ADU in Broomfield?

Broomfield’s municipal fees are among the lowest in Colorado because ADUs share utilities with the primary dwelling (no separate water or sewer tap fees). Total municipal fees typically run $3K to $8K. The total project cost for a typical 490 sq ft detached modular ADU in Broomfield is structurally lower than the other four cities we cover, primarily because of the utility-side savings. For the broader cost framework, see our ADU Construction Cost pillar guide.

Do I need owner-occupancy to rent out my Broomfield ADU?

Not for long-term rental. Ord 2265 (effective September 16, 2025) eliminated Broomfield’s owner-occupancy requirement, aligning with HB24-1152. You can rent both your primary dwelling and your ADU long-term to non-owners.

Can I Airbnb my Broomfield ADU?

Only if the property is your principal residence. Broomfield’s STR licensing program (Ch. 5-39) requires any STR — on the primary, the ADU, or another structure — to be on the host’s principal residence. If you live in the primary and STR the ADU, that’s permitted. If you don’t live on the property, you cannot STR.

Do I need a separate water tap for a Broomfield ADU?

No. ADUs tie into the principal dwelling’s existing water and sewer connections. No separate water tap, no separate sewer tap, no separate utility license. This saves $5K to $25K versus other Colorado cities. Septic users need Health and Human Services sign-off to confirm the septic system can handle the added fixture load.

What’s the Broomfield ADU size limit?

500 sq ft floor on any qualifying lot (you can always build at least 500 sq ft). Above that, the ADU is capped at 50% of the principal dwelling’s footprint (excluding garage and porch) or 800 sq ft, whichever is less.

What is the cladding rule?

Broomfield requires ADUs to be “designed to be consistent with the design of the principal dwelling unit.” On lots without property-specific design standards, the ADU must be clad in material similar to the principal structure. RVs, trailers, mobile homes, and shipping containers are prohibited. Manufactured, modular, and tiny homes are allowed if on a proper foundation and clad to match.

When is parking required for a Broomfield ADU?

In most cases, no parking is required. Three total spaces are required (two for primary, one for ADU) only when BOTH of these apply: the adjacent street prohibits on-street parking AND the lot is NOT in a Parking Reduction Area. Verify your lot’s PRA status with Broomfield Planning before assuming parking is or isn’t required.

What is the Declaration of Use?

A document recorded against the property title before Certificate of Occupancy (for detached ADUs). It states the size and location of the ADU and ties it to the property in the public record. Future title searches will surface the Declaration. The form is fillable on broomfield.org.

Can my HOA block my Broomfield ADU?

No. HB24-1152 voided HOA outright bans on ADUs in Subject Jurisdictions including Broomfield. HOAs can still apply aesthetic standards that apply to the primary residence. Contact your HOA before submitting the building permit — Broomfield’s ADU page specifically directs homeowners to do this. The codified preemption is at CRS 38-33.3-106.5.

How Olerra Builds in Broomfield

We build detached modular Flex Flat ADUs across the Front Range, Broomfield included, on a fixed-price contract. Once you sign, the unit price, foundation, site work, utility hookups (sharing with the primary), permits, and install are locked. No change orders unless excavation reveals something truly unforeseen, and even then we walk you through the change before it happens. For the broader cost framework, see our .

Our property check confirms what your specific Broomfield lot allows under Ord 2265, setbacks, PRA status, design-consistency requirements, and (for septic properties) Health and Human Services capacity. The shared-utility default makes Broomfield projects structurally cheaper than other Front Range markets we serve. Our walks the full five-step sequence from property check to keys, typically 3 to 6 months from contract signing.

Notes from Broomfield projects

Practical things that save time and money on a Broomfield ADU project, learned from doing this on actual lots.

Verify your PRA status before assuming no parking is required. Broomfield’s conditional parking rule triggers only when both (a) no adjacent on-street parking AND (b) lot not in a Parking Reduction Area. Most lots clear at least one of those tests, but verifying the PRA boundary with Broomfield Planning is a 5-minute call that confirms whether your project needs a $10K to $30K parking pad.

Plan the cladding match early. Broomfield’s cladding rule requires ADU material similar to the principal. If your primary home has fiber-cement lap siding in a specific color and exposure, your ADU should match that profile. This is a design-stage decision, not a permit-stage decision. Bring the primary’s siding spec to the design conversation upfront.

Septic properties need Broomfield HHS sign-off. If your lot is on a septic system rather than municipal sewer, you need Broomfield Health and Human Services to confirm the septic can support the ADU’s added fixture load. Older septic systems may need upgrade or replacement; this can add 2 to 4 weeks to your timeline and $5K to $20K depending on scope.

The Declaration of Use is recorded forever. The Declaration of Use for detached ADUs gets recorded against the property title with the Broomfield Clerk before CO. Future buyers will see it during their title search. This isn’t a deal-breaker for resale, but it’s permanent on the chain of title. Make sure the recorded size and location match what you actually built.

Manufactured and tiny homes are allowed if clad to match. Broomfield specifically permits manufactured, modular, and tiny homes as ADUs — but they must be on a permanent foundation and clad in material similar to the principal. Factory tiny homes on wheels or chassis-based units are not compliant. If you’re considering a manufactured or tiny home, confirm with Broomfield Planning that the specific unit and foundation plan meet the code before purchasing.

Shared utilities means no separate license either. The shared-utility default isn’t just about no tap fee — it also means no separate utility account or license for the ADU. Your monthly water and sewer bill stays as one account tied to the primary. For long-term rental management, you’ll need to factor this into how you bill tenants (or absorb the utility cost).

HOA coordination is named on the city page. Broomfield’s official ADU FAQ explicitly directs homeowners to “contact your HOA before submitting a building permit.” HB24-1152 voids outright bans, but reasonable aesthetic standards can still apply. Most Broomfield HOA pushback happens on exterior color, roof material, and visibility from common areas — getting the HOA aligned early avoids a redesign later.

Broomfield ADUs are the cheapest to build of the five cities we cover. The shared-utility default alone saves $5K to $25K. The conditional parking rule rarely triggers. The cladding rule adds design discipline but not cost. If you’re comparing Broomfield to Denver or Boulder for ADU investment, the utility savings often make the case on their own.

Talk to a Builder Who Knows Broomfield Rules

The fastest way to move from rules-reading to a real build is a property check on your specific lot. Zone eligibility, setbacks, PRA status, design-consistency requirements, and (for septic properties) HHS capacity all shape what’s actually buildable.

No spec house. No long sales call. A real number based on your real Broomfield lot.
