Building in Greater Houston, explained

Neighborhood by neighborhood, jurisdiction by jurisdiction — what the review actually involves, what it costs, and where projects lose months.

A pale white oak studio table in daylight from a black-framed window onto live oaks, holding a rolled survey plat tied with cord, a clear tube of grey-brown clay soil core, a scale ruler, a white card model of a flat-roofed modern house, a stack of linen-bound folders, a block of pale limestone and a slab of white plaster

What the design fee covers on a Greater Houston house — and what sits outside it

Architectural and engineering design for a new custom home runs $7 to $12 per square foot at the Simple finish level, so $21,000 to $36,000 on 3,000 sq ft. That buys the drawings, the coordinated engineering and the answers to review comments; it does not buy the survey, the soil report, the permit fees or the construction itself.

Permits & Process
 Back garden at golden hour with a weathered cedar plank fence across the frame, a wooden utility pole at the left carrying overhead lines, a small green utility box in the mown lawn, and beyond the fence a two-storey white plaster house with a dark roof and matte black windows under a large live oak

Easements on a Houston lot — utility, drainage and aerial, and what you can build on or near them

An easement is a recorded right that someone else holds over a strip of your lot. You still own the land, but you generally cannot put a house, a pool or a foundation in it, and an aerial easement reaches into the air above the ground as well. Here is how the common kinds work, which one controls when they overlap, and how to find them before you design.

Explainers
 A new two-storey infill house in white plaster and vertical white oak siding with a matte black standing-seam gable roof, tall black-framed windows and a deep covered porch on slim black posts, set between older gabled bungalows with front porches and shaded by a large live oak in late-afternoon light

Building in the Heights — no zoning, so three other rulebooks decide the house

The Heights is inside the City of Houston, which has no zoning, so no ordinance sets a height, a side setback or a coverage limit for a typical Heights house. What decides the size and shape of the house instead is the recorded plat, any deed restrictions that still bind the lot, and — on many blocks — a historic district review that comes before the building permit.

Neighborhood guides
 Low ground-level view of a front lawn where a rebar survey rod with bright pink flagging tape stands in the grass beside a concrete driveway, a weathered cedar fence post at the left edge, and behind it a single-storey house in cream plaster with a limestone entry, a wood front door, matte black windows and a dark hipped metal roof under a large live oak in low sunlight

When the survey and the plat disagree — what it means and what to do before design starts

When a current survey and the recorded plat disagree, the gap is almost always one of five things — a measured dimension, a disturbed corner, an easement recorded after the plat, a replat, or something built across a line. Most are small and settle with a note from the surveyor; a few change what you can build, and all of them are cheapest to resolve before design starts.

Permits & Process
 A low single-storey modern house in cream limestone and white plaster under dark standing-seam hipped roofs, with a tall wood front door, set among tall pines and live oaks behind a broad lawn and a curving gravel drive in low morning sun

Building in Memorial — one name, six villages and a slice of Houston

Memorial is a neighbourhood name, not a permitting authority. A lot there can sit in the City of Houston or in one of six separate villages, each with its own council, its own code and its own building official, so the first job on any Memorial lot is to find out which one governs it.

Neighborhood guides
 A two-storey modern house in cream plaster over a limestone base, with tall black-framed windows, a wood front door under a flat black canopy and a mature live oak arching over the lawn; a wet concrete ribbon driveway with a grass strip down the middle runs back to a detached garage, beside a stepping-stone walk with pebble joints and a planted bed of grasses and river stones

Impervious cover — what counts, and why the driveway matters as much as the house

Impervious cover is every surface on your lot that water cannot soak through — the roof, the driveway, the walks, the patio, the pool deck — measured as a share of the lot. It is a drainage rule rather than a building rule, so it counts things lot coverage ignores, and on a tight Houston-area lot the paving can push a project past a limit the house alone never would.

Explainers
 A new single-storey house in white plaster over a limestone base, with a dark standing-seam metal hipped roof, black-framed windows and a tall wood front door, behind a wide curving concrete driveway, a mown lawn and young street trees, with flat open prairie stretching to the horizon at sunrise

Building in Katy — first find out which Katy your lot is in

A Katy address can sit inside the City of Katy, in unincorporated Harris County, in unincorporated Fort Bend County or in Waller County, and the City of Katy is a small part of what people call Katy. Which of those governs your lot decides who reviews the house, which rules apply and how long the permit takes — so it is the first question, before any design.

Neighborhoods
 A single-storey pale brick ranch house with a dark hipped roof and black-framed windows, joined at the back by a new two-storey addition whose lower floor is finished in white plaster with tall black-framed glass doors while the upper floor is still bare timber framing and sheathing, seen from the side yard under a large live oak with a stepping-stone path, lawn and stacked lumber and stone

Renovate, add on or rebuild — how to decide on a Greater Houston house

Add on when the existing house is sound and only short of space; rebuild when it needs a whole-house renovation anyway, because at that point the two cost about the same. On this site's figures, adding 800 sq ft to a 2,400 sq ft house costs $160,000 to $196,000, while renovating the whole house as well brings the total to $520,000 to $652,000 — overlapping the $576,000 to $704,000 of building 3,200 sq ft new.

Permits & Process
 A freshly poured concrete foundation standing well above the bare soil of a Houston lot, its edge still boxed in timber formwork and white plumbing stubs rising from the slab, with a male builder in a cap holding a tall grade rod beside a laser level on a yellow tripod, and a finished cream plaster and limestone house with broad limestone steps and a white oak door under live oaks behind

Finished floor elevation — what sets it, and what it moves

Finished floor elevation is the height of the top of your ground floor, stated against a fixed survey datum rather than against the dirt. In Greater Houston it is set by whichever is highest of the floodplain rule, drainage, the sewer and the deed restrictions — and once it is set, it moves the height limit, the steps, the driveway and the foundation with it.

Explainers
 A single-storey house in cream plaster over a limestone base, with a dark standing-seam metal hipped roof, matte black steel windows and a white oak front door reached by broad limestone steps, set among tall pines and a spreading live oak, with a crushed-gravel driveway curving past a shallow grassed swale across the front lawn

Building in Cypress and unincorporated Harris County — what sets the envelope when nothing does

Outside city limits in Harris County there is no zoning and no county setback. The recorded plat and the deed restrictions are the whole envelope, and the county's own review is about floodplain, platting and driveway access — not about how big or how tall the house is.

Neighborhoods
 A pale stone-coloured architectural model of a flat-roofed two-storey house with a long covered porch on a white oak studio table, beside unrolled yellow tracing paper with pencil floor plans and a row of samples — white oak, rough limestone, white plaster and matte black metal — with a matte black desk lamp, a tall black-framed window onto live oaks, and one male architect studying a pin-up wall of drawings in the background

What gets decided in each design phase — and when changing your mind starts to cost

Schematic design settles the size, shape and placement of the house; design development settles how it is built and what it is made of; construction documents turn those decisions into the drawings a city reviews and a builder prices. For a new custom home in Greater Houston the three phases take 10 to 20 weeks, and a change costs little in the first, real redrawing in the second, and sometimes a second round of plan review in the third.

Permits & Process
 A male surveyor in a work shirt and cap sighting through a yellow total station on a tripod at the edge of a cleared lot of bare soil, its boundary marked by wooden stakes with orange flagging and thin string lines, a prism pole at the far corner, and behind it a white plaster and pale limestone house with a white oak front door and dark roof under mature live oaks

What a survey shows that an appraisal does not

A survey locates your lot on the ground — its boundary, its corners, the building lines and easements from the plat, and where every existing structure sits against them. An appraisal gives an opinion of what the property is worth. You can design a house against the first; you cannot design one against the second.

Explainers
 A two-and-a-half-storey house in cream plaster with matte black steel windows and a white oak front door under a plaster entry surround, a small top floor set back behind a parapet with a band of windows, seen across a street between two large live oaks, with a lawn and clipped hedges in front and a paver driveway with a grass strip running down the side to a garage set well back at the rear

Building in West University Place — what must stay open, and where a third floor may look

West University Place does not cap lot coverage the usual way. Its single-family district requires 45% of the site to stay open and 35% to stay pervious, caps the framed area of every building on the site at 80% of the lot, and bars any third-floor viewpoint from looking directly into a neighbour's privacy zone.

Neighborhoods
 Eye-level view down an asphalt residential street under mature live oaks, with a flat-roofed white and limestone house behind a concrete curb, gutter and sidewalk on the left, and on the right a limestone house with a dark metal hipped roof and a wood front door whose concrete driveway crosses a grassed roadside drainage ditch over a round culvert, in late-afternoon light

Which city or county permits your lot — and why a Houston address will not tell you

The authority that permits a house is decided by where the lot sits, not by the city printed on its mailing address. A Houston address can fall inside the City of Houston, in unincorporated Harris County, or inside a smaller city such as Bellaire or West University Place — and each has its own review time, its own fees and, in the incorporated cities, its own limits on what you can build.

Permits & Process
 Elevated view over a new residential street, with a single-storey house in pale stone and white walls under a dark hipped roof beside a vacant lot of bare soil and patchy grass marked out by thin survey stakes, a pond and mature trees behind, and a concrete street and sidewalk in the foreground

What a plat is — and why it outranks the ordinance in Houston

A plat is the recorded map that created your lot — its dimensions, its building lines, its easements and the street it faces. In the City of Houston, which has no zoning, the plat and the deed restrictions are the envelope, and Chapter 42 of the city code says outright that a deeper private building line controls.

Explainers
 Two neighbouring two-storey houses seen from the sidewalk, one with white walls over a limestone base and a white oak entry canopy, the other in pale limestone, both with matte black windows and dark metal roofs, separated by a narrow strip of turf between paved paths that run back to a fence, with a young tree and clipped hedges in the front yards

Building in Pearland — why the date on your plat sets your setbacks

In Pearland two lots on the same street can carry different side setbacks, because lots platted before 27 February 2006 may use 5 ft side yards where newer lots need 7 ft 6 in. The rear yard can move by 10 ft as well, depending on whether a landscape reserve was recorded behind the lot.

Neighborhoods
 A two-storey house at the framing stage, pale timber stud walls and roof framing standing on a fresh concrete slab beside a limestone wall, with a male carpenter marking up an open drawing set on a plywood table on sawhorses, stacked lumber and mature live oaks behind him in low afternoon sun

What a permit drawing set contains — and what the builder still needs from it

A permit set holds the sheets a plans examiner needs to verify the house complies — site plan and drainage, foundation, floor plans, roof plan, elevations, sections and sealed structural drawings. A construction set adds the sheets a builder needs to build it without guessing. For a custom home in Greater Houston that usually means 20 to 45 sheets, and the gap between the two is where change orders come from.

Permits & Process
 A two-storey modern house on a corner lot, white plaster above a limestone base with matte black windows, a low limestone garden wall along the front lawn, a concrete driveway running back to a side-facing garage, and a mature live oak overhanging the street

What lot coverage counts — and what it does not

Lot coverage is the share of your lot the building footprint may occupy, and every Houston-area city defines it differently — 40% in Sugar Land, 55% in most of Bellaire, 60% in Pearland, and in West University Place not as coverage at all but as a minimum open area. On a typical lot the setbacks usually bind before the coverage cap does.

Explainers
 A single-story stone and brick custom home set well back from a suburban street, with a gabled entry, two street-facing garage doors, a wide concrete driveway and mature oaks shading the front lawn in late afternoon light

Building in Sugar Land — what the city controls and what your HOA controls

In Sugar Land two separate approvals govern a custom home or an addition — the city's permit and your subdivision's deed restrictions. They test different things, they run on different clocks, and the private one is usually the stricter of the two.

Neighborhoods
 A stack of large-format architectural drawings open on a white oak desk beside two rolled drawing sets, a black steel scale rule, two pencils and a white mug of coffee, with a limestone window sill and a distant city skyline through the window behind

What happens during plan review, and why your permit comes back with comments

Plan review is a checklist run against your drawings by several reviewers at once, and comments are the normal result rather than a failure. In the City of Houston a new house typically clears review in 4 to 10 weeks; the resubmittal cycle inside that window is what most schedules get wrong.

Permits & Process
 A single-storey modern house set back behind a clipped front lawn on a Houston residential street, with a concrete walk, a grass verge and a curbside oak in the foreground

What a building setback actually measures from

A setback is measured horizontally from your property line to the nearest part of the building — not from the curb, the sidewalk or the fence. Which line governs comes off the recorded plat, and it decides how big a house the lot will hold.

Explainers

Building a custom home in Bellaire — what the rules actually allow

Bellaire is its own city with its own building department, and its limits are stricter than Houston's. What that means for the size of house you can build, what plan review costs, and how long it takes.
