What you can build on a plot in Romania is set by the local urban plan, not by the size of the land. Four numbers decide it: the POT (how much of the plot you can cover), the CUT (how much floor area you can build), the height regime, and the setbacks from the street and the neighbours. All four are on the plot's urbanism certificate. Land outside the built-up area (extravilan) is a different story: you usually can't build a house there at all.
In short
Where the rules come from: the general urban plan (PUG) and its local regulation (RLU), or a zonal plan (PUZ) where one applies. Where the local rules are silent, the national planning rules apply (HG 525/1996).
Where to read them: an urbanism certificate for information (Law 169/2026, art. 254). Anyone can ask for one, and the legal deadline is 15 working days (art. 257 alin. (4)).
POT = built footprint ÷ plot area. CUT = total floor area ÷ plot area (art. 584).
The tightest rule wins: POT, CUT, height and setbacks each give a different maximum, and the smallest one is your real limit.
Extravilan: a house isn't on the list of what you can build. Making the land buildable takes a zonal plan, and that's long and uncertain.
Buy for the rules as they are, not for the rules you hope to change.
Where do a plot's rules come from?
From the local urban plan for your area. The urbanism certificate is where you read them.
The general urban plan (PUG) covers the whole city or commune. Its local regulation (RLU) splits the territory into zones (UTR) and sets the rules for each one.
A zonal plan (PUZ) sets more detailed rules for some areas, such as new residential areas or historic centres.
The national planning rules (Regulamentul General de Urbanism, HG 525/1996) are the baseline where the local rules are silent. They're still in force under the new code.
The urbanism certificate lists, for your plot (art. 253 alin. (4)):
whether it's inside or outside the built-up area;
protected zones and building bans;
the zone (UTR) and permitted uses;
the POT and CUT;
the minimum and maximum plot sizes;
the buildable area on the plot;
access, parking and alignment to the street;
the minimum and maximum height;
the utilities in the area.
Ask for an urbanism certificate for information before you make an offer. It's the purpose the code created it for (art. 254): anyone can request one for any plot.
Inside or outside the built-up area?
This is the first question for any plot. Inside the built-up area (intravilan), you build by the local rules. Outside it (extravilan), you mostly can't build a house.
Intravilan is the built-up area of a locality, as set by the general urban plan.
Extravilan is everything between that limit and the administrative boundary (art. 152 alin. (1)). The general plan divides it into agricultural, forest and future urbanisation zones and others (art. 152 alin. (2)).
"Intravilan arabil" is still intravilan. "Arabil" is the land's use category in the land book. What you can build is set by the local rules, not by the use category.
What can you build on land outside the built-up area?
Not a family house, in most cases. The law lists what's allowed there, and making the land buildable takes a zonal plan.
What the law allows outside the built-up area:
Only the investments listed in the land fund law (Law 18/1991, art. 92 alin. (2) and (3)), built according to the territorial or general plan, or based on a detailed urban project (CATUC art. 152 alin. (3)).
On the best agricultural land (quality classes I and II), on land with irrigation or drainage works, on vineyards and orchards, and in national parks, reserves and heritage sites, building of any kind is banned (Law 18/1991, art. 92 alin. (1)).
The exceptions are specific: buildings that serve farming activities, military buildings, major roads and railways, power lines, oil and gas works, pipelines and water works (Law 18/1991, art. 92 alin. (2)). A family house isn't on the list.
How land outside the built-up area becomes buildable:
It has to be brought into the built-up area through the general plan or a zonal plan, with a prior opinion from the agriculture ministry on the land's quality class (CATUC art. 153 alin. (1)).
Taking the land out of agricultural use comes with a fee (Law 18/1991, art. 92 alin. (4)). Owners under 40 who want to build a home on up to 500 m² of agricultural land are exempt from the fee (art. 92 alin. (6)).
A zonal plan that changes the approved rules now needs reasons that are well founded "from the perspective of the general interest", and a prior initiation opinion from the city hall (art. 62 alin. (3) lit. c) and art. 69). For a single plot, that's long, costly and far from certain.
If you're buying land outside the built-up area to build a house, assume you can't until the urbanism certificate says otherwise.
The four rules that cap what you can build
Learn these four and you can read any plot's urbanism certificate.
POT: how much of the plot you can cover. The POT (procent de ocupare a terenului) is the building's footprint divided by the plot area, as a percentage (art. 584). The footprint includes cantilevered floors and balconies. Where the local rules don't set a POT, the national rules cap it, e.g. at 30% in rural zones and 35% in purely residential zones with houses of up to three levels (HG 525/1996, annex 2).
CUT: how much floor area you can build. The CUT (coeficient de utilizare a terenului) is the total floor area of all levels divided by the plot area (art. 584). Spaces lower than 1.80 m, attics that can't be converted, and basement parking don't count. A CUT of 0.9 on a 500 m² plot allows 450 m² of floor area. The CUT fixes how much house you get; it doesn't fix the shape.
Height regime: how many levels. The height regime (regim de inaltime) is the maximum number of above-ground levels, written as P (ground floor), E (storeys) and M (mansard). The demisol and the mansard count as levels (art. 584). The local rules usually add a maximum height in metres. Where there's no zonal plan, the national rules also keep a new house within two levels of its immediate neighbours (HG 525/1996, art. 31).
Setbacks: where on the plot you can build. Three sets of distances apply:
From the street: the local rules say whether you build on the street line (aliniament) or set back from it. Where a setback is required, the strip in between can't be built on, apart from fences, access, bin areas and low terraces (art. 584).
From the neighbours: at least 60 cm from the boundary, and 2 m for windows or balconies that look onto the neighbour's land (Civil Code, art. 612 and 615). The local rules often require more, and fire-safety distances also apply (HG 525/1996, art. 24).
Within the plot: distances between buildings on the same plot, where the local rules set them.
A worked example
Illustrative figures. Your plot's numbers come from its urbanism certificate.
A 500 m² plot, 20 m wide and 25 m deep, in a residential zone. The local rules set POT 35%, CUT 0.9, height P+1E+M, a 5 m setback from the street, 2 m from the side boundaries and 5 m from the rear.
Setbacks: the buildable area is (20 − 2 − 2) × (25 − 5 − 5) = 16 m × 15 m = 240 m². That's where the footprint can go.
POT: 35% × 500 m² = 175 m² maximum footprint. That's smaller than the buildable area, so the POT is the limit on the footprint, not the setbacks.
CUT: 0.9 × 500 m² = 450 m² maximum total floor area.
Putting it together: a ground floor and first floor of 175 m² each (350 m²), plus a mansard of up to about 100 m² counted floor area, reaches the CUT. A single-storey house tops out at 175 m², because the POT stops you first.
Each rule gave a different number, and the tightest one decided at each step. That's the whole skill: change the plot's width, the POT or the setbacks, and a different rule takes over.
Looking at a plot and not sure what it allows? Book a free 45-minute Office Hours session, send us the cadastral number or the urbanism certificate, and we'll tell you what the rules allow, which one limits you first, and whether the house you have in mind fits.
How big does a plot need to be, and how wide at the street?
The local regulation sets the real minimum. The national rules give the common reference.
The national planning rules set, for parcellations, a street frontage of at least 12 m and an area of at least 200 m² per plot for detached or semi-detached houses. For terraced houses it's 8 m and 150 m². The plot must be at least as deep as it is wide (HG 525/1996, art. 30).
These are the figures most people quote, but formally they apply to parcellations of four or more plots. The local regulation sets the minimum for your zone, and it's often stricter.
Your plot's minimum and maximum sizes are on the urbanism certificate (art. 253 alin. (4) lit. c)).
What the site itself adds
Once the rules are clear, the land makes its own demands.
Access: a plot needs access to a public road, directly or through a right of way, wide enough for fire engines (HG 525/1996, art. 25).
Utilities: check what reaches the plot: water, sewage, electricity, gas. The urbanism certificate lists the networks known in the area (art. 253 alin. (4) lit. d)). A plot without sewage needs space for a septic tank or a local treatment unit.
Slope, flood and landslide areas: they change the foundations, the cost and sometimes what's allowed at all.
Easements and encumbrances: rights of way, utility easements, mortgages and disputes are in the land book. Read the extract before you sign.
The neighbours: windows already facing your plot and existing walls on the boundary affect where you can build.
Should you count on changing the rules?
No. Buy the plot for the rules it has today.
Raising the POT, CUT or height, or reducing the setbacks, takes a zonal plan that modifies the approved rules (art. 62 alin. (4)).
Under the new code, that's allowed only in situations "temeinic fundamentate din perspectiva interesului general" (well founded from the perspective of the general interest), after a prior initiation opinion from the city hall (art. 62 alin. (3) lit. c) and art. 69).
Even when it's possible, a zonal plan takes many months, costs real money and can be refused. Price the plot on what it allows now.
Before you make an offer: the checklist
Eight checks, in order. Any one of them can rule a plot out.
Land book extract: owner, easements, mortgages, disputes, and the land's use category.
Urbanism certificate for information: intravilan or extravilan, zone, permitted uses, POT, CUT, height, alignment, minimum plot size, protected zones and building bans (art. 254).
Access to a public road, directly or through a registered right of way.
Frontage and shape against the local minimum, and whether the plot is deep enough.
The buildable area once the street and boundary setbacks are taken off.
The limits: footprint from the POT, floor area from the CUT, levels from the height regime. The smallest one is your real house.
The site: utilities, slope, flood and landslide risk, neighbours' windows and walls.
A margin: don't buy a plot where your house only fits on paper, with nothing to spare.
