Spring Valley sits roughly 1.8x the Dallas citywide residential median of $295K. Market character is mid-to-upper-middle Far North Dallas suburban, materially below neighboring Preston Hollow ($1.5M-$2.5M) and Prestonwood ($650K-$1.4M). The single-family ranch pockets (where ADU analysis matters) run $450K-$700K and tend to be 1960s-1970s brick construction on 8,000-12,000 sqft lots. Texas Residence Homestead 10% appraisal cap (Tax Code Sec. 23.23) limits year-over-year homestead assessment growth. Large stretches of Spring Valley are not owner-occupied single-family and therefore do not receive the homestead cap. The no_county bucket carries the same property-tax rate composite (city + ISD + county + special districts) as the dallas-county bucket — the synthetic no_county label reflects only USPS county-attribution absence, not a different tax jurisdiction.

Spring Valley's HOA prevalence is materially lower than single-family Preston Hollow (~55%) or Prestonwood (~95%) because (1) the locale is mostly multifamily where condo-regime rules govern instead of HOAs, and (2) the single-family subdivisions that do exist are generally 1960s-1970s mid-century tracts without the active-HOA infrastructure that defines Preston Hollow subdivisions. Most Spring Valley single-family parcels with recorded deed restrictions have unenforced covenants or covenants that explicitly permit accessory structures with family-member occupancy.

• airport-noise-zone — Dallas Love Field AICUZ. Spring Valley sits ~7 miles north-northeast of Love Field and is generally outside the 65 dB DNL noise contour but may touch the 60 dB DNL contour on the locale's southern edge (along LBJ Freeway). DFW International Airport is ~13 miles west and the DFW noise contours do not reach the locale.
  Not a practical construction constraint. Noise attenuation is not required by Dallas residential code outside the 65 dB contour.
• flood-zone — Farmers Branch Creek and its tributaries flank portions of Spring Valley. FEMA-mapped Special Flood Hazard Areas (Zone AE) follow the creek corridors in narrow strips in the western portion of the locale toward the Dallas North Tollway. Most Spring Valley parcels sit on higher ground on the Austin Chalk upland and are Zone X. · +21d · +12% cost
  Approximately 5-8% of Spring Valley parcels touch mapped SFHA along Farmers Branch Creek. Those parcels require elevation certificates, floodplain-ordinance compliance, and higher flood-insurance premiums. The Dallas Midtown parcel itself is partially in mapped floodplain and has required substantial stormwater-management work.
• other — Valley View-Galleria Area Plan — adopted by the Dallas City Council as part of ForwardDallas successor planning and supported by a Tax Increment Financing district. Covers the core of the Spring Valley locale — roughly bounded by LBJ Freeway (I-635) on the south, Spring Valley Rd on the north, Preston Rd on the east, and the Dallas North Tollway on the west. The plan supports dense, walkable mixed-use redevelopment anchored on the former Valley View Mall site (now Dallas Midtown).
  Not directly ADU-relevant. The Area Plan governs mixed-use, commercial, and multifamily redevelopment; it does not enable or constrain single-family ADUs. However, owners of the minority single-family parcels inside the Area Plan boundary should expect (a) ongoing adjacent construction noise and traffic during Dallas Midtown buildout (2026-2035), and (b) meaningful upward pressure on both land value and rent levels as the TIF-supported project delivers.
• other — Multifamily-zoning predominance. The majority of Spring Valley parcels are multifamily (MF-1, MF-2, MF-3), mixed-use (MU-1, MU-2, MU-3), commercial (CR, MC), or Planned Development District zoning rather than single-family. Sec. 51A-4.510 (the ADU framework) does NOT apply to these parcels — additional units follow base-district density and FAR caps instead. This is the single most important structural factor for Spring Valley ADU analysis: the majority of parcels are outside the ADU framework entirely.
  Before any ADU design work on a Spring Valley parcel, the owner MUST confirm the base zoning is single-family (R-7.5(A), R-10(A), TH-1(A), or similar) via the Dallas GIS zoning viewer. If the parcel is MF-x, MU-x, CR, MC, or PD, the ADU framework does not apply and the parcel is either (a) already entitled for a denser residential configuration under its base zoning, or (b) regulated by a Planned Development District ordinance that sets its own use list.
