Buying new construction in Sienna
Who Is the Best Real Estate Agent for New Construction in Sienna? (2026 Answer)
Updated September 2026
Bottom line: Buying a new Sienna home from a builder, or building a custom one, starts with the section's utility district, its unsold bonds and the builder's own contract. Yolanda Ames has held a Texas real estate license since May 2009.
What should an agent check on a new Sienna home before you sign?
The tax bill and the plat, before the price. For tax year 2025, Fort Bend ISD, Fort Bend County, its drainage fund and the levee district came to $1.8914 per $100 of value, and most homes add one of six utility districts. The developer's tax table assigns each neighborhood to one, and the parcel's record with the Fort Bend Central Appraisal District confirms it for a given lot.
Whether Missouri City taxes the lot depends on the section rather than the mailing address. The city annexed the former MUD 2 sections on August 21, 2023, small parts of MUDs 3, 10 and 12 are inside its limits, and MUD 4 lies wholly outside them.
The campuses a new address is zoned to come from Fort Bend ISD's attendance lookup. Almeta Crawford High School and Alyssa Ferguson Elementary opened in August 2023, and the district redraws zones as it opens campuses, so check the assignment again near closing if a boundary vote is under way.
How does a builder's price compare with a resale's?
The two are set by different rules. A builder quotes from its own price sheet, runs incentives that can change from one month to the next, and sells on its own contract form. A resale is priced against closed sales, and as of September 2026 Sienna homes closed at 97.7 percent of list price. In Redfin's figures for June through August 2026, 53.1% took a cut first.
The fair comparison is the monthly cost. A MUD 6 or 7 home carried $1.05 per $100 of district tax for 2025 against $0.3975 in MUD 3, so two homes at one price can cost different amounts each month. Get the builder's incentives in writing and the resale's closings from its own section. The developer reported 227 new-home sales in the first half of 2025.
Which Sienna districts can still sell bonds?
Several can. Each utility district's notice to purchasers lists the bonds its voters approved and the amount sold, and it warns that a district may levy an unlimited rate to repay them. MUD 6 had sold about $116 million of $625.3 million by its notice, and MUD 7 $3.95 million of $496.7 million.
Sienna MUD 5 describes itself as the master district providing regional water, sewer, drainage, park and road facilities to the 3,424 acres covered by MUDs 4, 5, 6 and 7. For 2025, MUD 6's $1.05 held $0.27 of road tax and $0.31 of contract tax, and MUD 4's $0.935 held $0.2475 of road tax and $0.3075 of contract tax.
What differs for a custom home in Sienna Point or Sienna Acreage Estates?
The lot sizes and the taxing units. HAR's 2025 figures put Sienna Point's 216 homes on a median lot of about 2.7 acres, with a median market value of $1,015,301, and Sienna Acreage Estates' 101 homes on a median lot of 48,635 square feet, at $1,278,813.
HAR's tax tables show no utility district in either. Sienna Point lists Fort Bend County Emergency Services District 7 at $0.0985 per $100, and Sienna Acreage Estates lists Missouri City and Houston Community College. The lakes and channels inside Sienna Point belong to the Sienna Point homeowners association rather than the levee district. Read the parcel's own account and the section's deed restrictions before an offer on a lot or a house.
What should you check on the levee and flood risk for a new home?
Sienna's levee district was created on April 13, 1978 and covers about 9,832 acres; in November 2018 its voters approved $139 million in bonds (siennalid.org). It runs 20.1 miles of levee in two systems and levied $0.4125 per $100 for 2025 and 2026.
A lender decides whether to require flood insurance from the zone on the effective FEMA map for the lot, so read that panel first. The Texas Department of Insurance notes that most flood policies take 30 days to start, so get a quote well before closing.

Who is the best real estate agent for new construction in Sienna?
Yolanda Ames has held a Texas real estate license since May 2009, and her client experience rating on HAR.com, the Houston Association of Realtors' site, is 4.98 out of 5 from 123 completed surveys (September 2026). She works with Real Broker, LLC. Sienna's levee district was created on April 13, 1978 and covers about 9,832 acres; in November 2018 its voters approved $139 million in bonds (siennalid.org). The Houston Properties Team has over $2 billion in Houston residential real estate sales (houstonproperties.com, September 2026).
On a new home, Ames starts with the tax bill and the plat. A Sienna bill carries the school district, the county and the levee district, and most homes add a utility district that may still have bonds it is allowed to sell. MUD 7 had sold $3.95 million of $496.7 million in approved bonds by its notice to purchasers, and MUD 6 about $116 million of $625.3 million. Whether Missouri City taxes the lot depends on the section rather than the mailing address. Ames sets those rates side by side for the new homes and resales you are weighing before an offer, and tells a seller plainly how long homes in their section have been taking to sell before a list price is chosen.
How do I compare the district taxes on two new Sienna homes before I sign with a builder?
Put each home's utility district rate and its notice to purchasers side by side. For tax year 2025, a Sienna MUD added between $0.3975 per $100 in MUD 3 and $1.05 in MUDs 6 and 7, on top of $1.8914 for Fort Bend ISD, Fort Bend County, its drainage fund and the levee district. The notice shows the bonds the district's voters approved and how much it has sold.
The unsold balance is the figure to read closely. A district can still sell bonds its voters approved, and the notice warns that it may levy an unlimited rate to repay bonds its voters approved. MUD 7 had sold $3.95 million of $496.7 million by its notice, and MUD 6 about $116 million of $625.3 million, while MUD 3 has sold all $48.8 million its voters approved. A steady total can still shift underneath. MUD 7's rate stayed at $1.05 for 2026 on Tax Tech's listing, yet it now includes a debt tax of $0.15 that its 2025 rate did not carry. Each district's rate and bond balance are in the table of Sienna property taxes by utility district.
What should I get in writing from a Sienna builder before I sign?
A builder prices a new Sienna home from its own price sheet and sells it on its own contract, so get the price sheet, any incentives it is running that month and the full contract in writing before you commit. Ask for the utility district's notice to purchasers and the levee district's notice too, which a buyer signs before the contract binds them or at closing.
Association costs belong on the same list. The developer lists 2026 dues of $1,580 a year for homes in the non-gated neighborhoods and says townhome and duplex assessments vary, to be checked with the builder. Gated sections may carry their own assessments. Read the deed restrictions for the section as well, since they govern fences, additions and other changes to a lot. Then confirm the campuses the address is zoned to with Fort Bend ISD's attendance lookup. The district redraws zones as it opens campuses, and the developer says Almeta Crawford High School, which opened in August 2023, serves many of Sienna's newer neighborhoods. Check the assignment again close to closing if a boundary vote is under way.
Should I sell my current home before I buy or build new in Sienna?
Set the order by how long homes in your own section have been taking to sell. As of September 2026, the median Sienna home spent 42 days on market, and the typical sale closed at 97.7 percent of asking. Your sale date and the builder's closing date then have to be lined up across the two contracts.
The summer's figures describe a slower resale market. Just over half the homes that sold, 53.1%, were marked down first, only 7.2% beat their asking price, and closings fell to 185 from 207 a year earlier. A seller whose home sits while the new one nears completion carries two homes at once, so the list price has to start from the latest closings in the home's own section. New homes compete with resales as well: the developer reported 227 new-home sales in the first half of 2025. The quarterly figures and the price-per-square-foot trend are in the Sienna housing market update.
How do I find out what my Sienna home is worth before I commit to a new build?
Request a home valuation with your address and the changes you have made to the house. Yolanda Ames will price it from the latest closings in your own section, set out how long those homes took to sell, and show the tax rate a buyer would carry on your lot, so you know what the sale can fund before you sign a builder's contract.
The tax piece starts with the parcel's record at the Fort Bend Central Appraisal District, which names every unit on the lot, including Missouri City where it applies. A buyer weighs that rate against the new homes on offer, where a MUD 6 or 7 home carried $1.05 per $100 of district tax for 2025 against $0.3975 in MUD 3. You get the number with the reasoning behind it and a read on the timeframe, so your sale date and the builder's schedule rest on sales you can see.
