HOA rules by community · Washington City
Sienna Hills
Sienna Hills is a master association with twelve neighbourhood associations under it, each with its own manager and its own monthly dues. The master piece is small — $15 a month, folded into what your neighbourhood already charges. Most of the day-to-day answers come from the neighbourhood, not the master.
The landscape and wall rules below come from the community's design documents as read in this research. Where a document name, section number or revision date was not captured, we have not invented one, and we say so at the bottom. Where a rule sits against a newer Utah statute, both are stated and the reader should confirm with the association or an attorney.
Managed by Community Association Management (CAM), the Southern Utah arm of HOALiving, for ten of the twelve neighbourhood associations; ERA Brokers Consolidated and Paul Properties for the others. Confirm the current manager with your association before you rely on it.
Design review
The DRC window, and what the statute does and does not add to it.
- The Sienna Hills Design Review Committee runs a 30-day window on both the preliminary and the final submittal.1
- Utah has no statutory deemed-approval provision and no statutory review deadline, so whether that 30-day window operates as a deadline or as silence-equals-approval depends on the wording of Sienna Hills' own documents.2
- Utah Code § 57-8a-109(4) requires that a written denial specify each governing document provision the association relied on and the specific aspect of the plan that does not conform to it.2
- Utah Code § 57-8a-109(2) provides that an association may not charge a plan fee that exceeds the actual cost of reviewing and approving the lot plans.2
Landscape rules
Lawn proportions, rock, walls, and how they meet the Washington City ordinance and the county rebate.
- Sienna Hills recommends lawn at no more than 15% of the front yard and no more than 30% of the rear yard.3
- The community's landscape rules ask homeowners to minimise coloured rock and pea gravel.3
- White is not allowed on paint or on roofing at Sienna Hills.3
- Perimeter walls are limited to six feet and retaining walls to four feet.3
- Washington City's residential lawn ordinance is nearly identical to St. George's cap of 8% of lot size to a maximum of 1,500 square feet, and it applies to rehabilitated landscaping, not only to new work.3
- Utah Code § 57-8a-231(3)(b) provides that, except where reasonably necessary for erosion control, an association may not require a lot owner to install or keep in place lawn or turf in an area less than eight feet wide.2
4 more facts, with sources
- The Washington County Water Conservancy District's Water Efficiency Standards, October 2023, §2 state that where the standards conflict with a municipal ordinance or the requirements of a common interest community, the regulation providing the greatest water conservation benefit applies.4
- The county rebate pays $3 per square foot on the first 1,000 square feet and $2 per square foot after that, for projects completed before June 1, 2027, and requires living grass at the pre-conversion inspection.4
- The district accepts rock, bark, ungrouted stepping stones and permeable artificial turf as mulch, and requires the converted area to be free of bare soil and impermeable barriers.4
- A rebated conversion carries a conservation easement that continues in perpetuity, is recorded with the Washington County Recorder, and restricts only the converted portion of the property.4
Working on your house
Patio covers, landscape lighting, and who you are allowed to hire.
- Patio covers at Sienna Hills must match the roof surface, and enclosing a patio cover is prohibited.3
- Landscape lighting must be low voltage and approved by the DRC.3
- Utah Code § 57-8a-218(22)(c)(iii) and § 57-8a-212 bar restricting a lot owner from hiring a contractor solely because the contractor is not on the association's preferred vendor list, or lacks a licence that is not required by law.1
- Construction work hours in Washington County come from association documents rather than city code; no municipal code reviewed in this research contained them.3
Structure and management
One master, twelve neighbourhoods, three management companies.
- The master association is the Sienna Hills Community Association, 1593 Grapevine Crossing Rd, Washington UT 84780, 435-272-3621.2
- Master dues are $15 per month, included within each neighbourhood's own dues.2
- There are twelve neighbourhood associations: Copperleaf, Sienna Heights, Garden Homes, The Villas, The Casitas, Arroyo, Ladera, Paseos phases 1 to 3, Paseos phase 4, Desert Ravine, Escondido and Sendera.2
- Community Association Management manages ten of the twelve neighbourhoods and can be reached at 435-627-1776; CAM is the Southern Utah arm of HOALiving.2
- Copperleaf and Ladera are managed by ERA Brokers Consolidated at 435-628-3950, and The Casitas by Paul Properties at 435-674-3444.2
- Published neighbourhood dues range from $30 a month at Arroyo to $226 a month at Escondido, so which neighbourhood you are in changes the bill substantially.2
What the statute adds
Provisions that bear on the rules above.
- Under Utah Code § 57-8a-217, a board must deliver notice to lot owners at least 15 days before the meeting at which it adopts, amends or cancels a rule or design criterion, provide an open forum, and deliver the approved change within 15 days after.2
- Utah Code § 57-8a-217(4) provides that a rule or design criterion is disapproved if, within 60 days, at least 51% of all allocated voting interests vote to disapprove it at a special meeting called for that purpose.2
- Utah Code § 57-8a-208 requires a written warning before any fine, stating the violation and the provision violated, with not less than 48 hours to cure a continuing violation, and gives the owner 30 days to request an informal hearing.2
- Late fees are capped at the greater of 10% of the assessment or $50, with interest up to 1.5% per month, and a fee schedule must be adopted by rule and distributed to every owner before any such fee is imposed.2
- Under Utah Code § 57-8a-227(4)(a), an association must comply with a written records request within 10 business days, and § 57-8a-227(5)(b) gives the owner $25 per day beginning the eleventh business day if it does not.2
- If the association has an active website, § 57-8a-227(2)(a)(ii) requires the governing documents, the most recent approved minutes and the most recent budget and financial statement to be posted there free of charge.2
What we could not read
These are the parts of Sienna Hills’s documents we could not get to a verified copy of. We would rather say so than guess. Your association can give you the current versions, and Utah Code § 57-8a-227 says what they have to hand over on request.
- Document names, section numbers and revision dates
- A stale page on the community site
- Construction hours, deposits and contractor insurance
- Washington City outdoor lighting
- Whether association common areas qualify for the county rebate
