Office figures: Newsec, Q1 2026: 925,500 m² of offices in Riga; 9.5% of A-class and 10.7% of B-class space empty; 80,000 m² under construction (no single overall rate published on the page). Homes: our economic model’s conversion engine. Map built 2026-10-09.
One point per building, from public records, open data and cited reports. Filter by type, size and how sure the evidence is; open one to see who says so and whether it could become homes.
No open aerial photos: the Latvian Geospatial Information Agency's orthophoto service needs an account and its host answered robots.txt with a server error (503), and the City's map server geo.riga.lv answered robots.txt with an error — building cards show Esri's World Imagery instead.
Check any building in Riga: could it become homes, and could the EHC model work there?
The districts where empty space, the right zoning and a working neighbourhood come together, and the owners and programmes that open a door.
Holds about a third of the city's degrading buildings, many of them wooden houses and old industrial buildings; the former school at Avotu iela 44 is for sale.
Risk: Many degrading buildings are small wooden houses in mixed private ownership.
The left bank's older quarters carry the second-largest share of degrading buildings, and the City is selling the institution building at Alīses iela 3A.
Risk: Heritage rules in the wooden quarters raise restoration costs.
Riga's office market sits here, and the City's housing company offers 3,600 m² of empty offices at Amatu iela 4 in the Old Town.
Risk: UNESCO-listed historic centre: strict heritage rules, high prices.
Former schools and kindergartens emptied in 2026 — Skuju iela 28, Augusta Dombrovska iela 87, Baltā iela 22A, Lidoņu iela 10A, Parādes iela 24A — sit in these outer districts.
Risk: Far from the centre, in areas of falling school rolls; some are already set for sale by auction.
Decisions, auctions and closures that change what becomes available, and when.
Council decisions of 8 July, 26 August and 23 September 2026 put Baltā iela 22A, Avotu iela 44, Alīses iela 3A, Salacas iela 28, Parādes iela 24A and the Mazā Matīsa water tower up for sale.
1,575 buildings: 1,165 declared environment-degrading (283 category A safety risk, 715 B unkept, 167 C unused and harming the street) and 410 awaiting assessment; Latgales priekšpilsēta alone has 509.
Skuju iela 28, Augusta Dombrovska iela 87, Lidoņu iela 10A and others were vacated from 1 September 2026 with no decision yet on their future.
VNĪ auctioned Teātra iela 9 (1,891 m²) for €2.72 million and named Smilšu iela 7 (first half of 2026), Lāčplēša iela 1 and Valdemāra iela 32 (second half, the Central Statistical Bureau) for disposal.
Rīgas nami will build about 250 social flats on Dzelzavas iela for €15.4 million, due in late 2029.
From 3,186 households in 2020 to 1,656 at the start of 2025; the City owns about 11,000 flats for housing support.
1,189 buildings were on the grausti.riga.lv list, 16 of them City-owned and 16 State-owned; private owners restored about 1,300 such buildings in ten years.
