What an ADU Can Do for Houston Homeowners

Families across Houston add ADUs for many reasons. Which one fits you?

  • Multigenerational living. Give a parent or adult child a private spot with a full kitchen and bath.
  • Guest space. Keep visitors close but not in your living room.
  • Long term rental. A steady income stream on your property.
  • Short term rental. Check your deed restrictions and HOA rules first. We can help you check.
  • Home office or studio with real walls, real HVAC, and no kitchen smells on your laptop.
  • Caregiver quarters. Sleep nearby without living on top of each other.
  • Pool house or game room that does not track wet footprints into your home.

Life in Houston has its own rhythm. Maybe your student attends Rice or UH and needs an affordable place close to campus. Maybe you want a place for a visiting resident who rotates at the Texas Medical Center. Maybe you are in the Heights and want a classic garage apartment that matches the bungalow look around you. Or you are in Meyerland and want to build smarter after a flood. We plan ADUs for real Houston life.

Straight Talk on Rules Permits and HOAs

Houston does not have traditional zoning. That does not mean anything goes. Here is what matters for ADU Construction

  • Deed restrictions and HOAs. Many neighborhoods have rules on extra dwellings, height, and rental use. We read the documents and prepare the submittals.
  • Setbacks and building lines. City rules and your plat control how close you can build to a property line. Corner lots and lots with alleys have special rules.
  • Lot coverage. You can only cover a certain percentage of your lot with buildings. We measure and model to stay under the limit.
  • Parking. Off street parking may be required. Alley access can help, especially in the Heights.
  • Fire separation. The ADU must be a safe distance from the main house, or it needs fire rated walls. We plan this from day one.
  • Utilities. Water, sewer, gas, and electric must be sized and routed correctly. Separate meters are possible. A subpanel may be enough.
  • Floodplain rules. Parts of Houston sit in a flood hazard area. You may need a higher floor elevation, flood vents, or special foundation details. Learn more about floodplain basics from FEMA.

Permitting runs through the Houston Permitting Center. Your plans go to plan review for structural, mechanical, electrical, and plumbing. If your site is in the floodplain, we coordinate with Floodplain Management. We also manage inspections during the build. You do not have to stand in line at 1002 Washington Ave. We handle it.

Common Hurdles We Solve

Every lot is different. Here are common problems we solve in Houston

  • Deed restrictions and HOA approvals. We prepare drawings, material lists, and neighbor notices if needed. We track comments and adjust quickly.
  • Trees near the building area. We plan foundation and trench routes to protect roots. We follow City of Houston tree rules.
  • Narrow side yards. We plan delivery routes, staging, and crane lifts if needed. Alley deliveries are common in the Heights and Montrose.
  • Utility upgrades. Some homes need a new electrical service or a larger gas meter. We coordinate with CenterPoint and your water provider.
  • Drainage and detention. If added hardscape pushes you over a threshold, we add small detention or adjust your plan to stay under it.
  • Floodplain elevation. We plan pier and beam or a raised slab that meets elevation rules and still looks good.
  • Historic look. If you are near a protected district, we match siding profiles, roof shape, and window patterns. We respect the street.

Do any of these sound familiar? A quick site visit answers a lot of questions. Call 832-810-5377 to book it.

Our ADU Process

We keep a clear process so you always know the next step.

1. Phone Consult and Rough Budget

We start with a short call. You share your address, goals, and must haves. We look up your lot, flood map, and street view. In most cases we can give a rough price range on this call, based on similar builds in your area.

2. Site Visit and Measured Survey

We walk the property with you. We confirm clearances, utility locations, and access. We take photos and measure. We note trees, fences, and any drainage issues. We talk through the best spot and footprint.

3. Concept Plan and Free 3D Quote

This is where ideas get real. Our team drafts a concept plan with a 3D model. You can see roof shape, window placement, and the way the ADU sits in your yard. We include a scope and an itemized budget. The 3D quote is free. Tweak it as needed, then we lock in a plan that fits your goals and your lot.

4. Selections and Engineering

Pick exterior and interior finishes. We help you match your main home or create a clean modern look. We coordinate structural engineering and energy code details. We finalize MEP layouts so you get a quiet, efficient space. If you need design support we offer Architectural Services.

5. Permits and HOA

We submit to your HOA if you have one. We handle city permits through the Houston Permitting Center. We respond to plan review comments. You get status updates from your project manager.

6. Build

Our crews handle foundation, framing, roofing, windows, rough MEP, insulation, drywall, trim, cabinets, tile, and fixtures. We schedule inspections and walk you through milestones. We keep your yard organized and your neighbors informed. Learn about our Foundation Construction and Roofing Services.

7. Punch List and Turnover

We walk with blue tape and fix what you find. We show you how to use everything. You get final documents, including permit cards and manuals. Then you enjoy your new space.

Curious how long it takes? Design and permits often take 6 to 12 weeks on a normal lot. Construction can run 3 to 7 months based on size, foundation type, and weather. Heavy rain in spring can slow slab work. We plan around Houston weather and move fast when the sky is clear.

Types of ADUs We Build in Houston

ADU Construction covers many formats. Here are common options that work well across the city.

Detached Backyard Cottage

A small house in the back yard with a full kitchen and bath. Works well in neighborhoods with larger lots like Garden Oaks, Oak Forest, and Meyerland. Great for long term rental or family. Explore options similar to a detached suite with our Detached in law suite builder service.

  • Flexible size based on your lot and rules
  • Quiet and private
  • Easy to orient for shade and breeze

Garage Apartment Over a New or Existing Garage

Build above a new two car garage, or add living space above an existing garage if the structure allows it. This is a classic in the Heights, Montrose, and Midtown alley lots. See ideas that relate to Second story additions.

  • Parking below with a studio or one bedroom above
  • Uses vertical space to save yard area
  • Alley access keeps traffic off your driveway

Partial Interior Conversion or Attached Suite

Turn a detached garage into living space or attach a suite to the main house with a private entrance. This can be cost friendly if the shell is solid.

  • Keeps utilities close
  • Good for a caregiver or grandparents
  • Can share laundry or add a compact stackable

Consider our Garage conversions and Room Additions services for these paths.

Pool House or Flex Studio

Make a pool house that also sleeps guests. With a kitchenette and full bath, it can flex from party room to guest suite.

  • Easy to clean finishes
  • Large doors that open to the patio
  • Outdoor shower option

Planning a future pool as well? Explore our Pool Building service.

Not sure what fits? We test layouts in 3D and show you how each option impacts cost, permits, and yard space.

Smart Design for Houston Lots

Houston has clay soils, big sun, and sneaky rain. Good ADU design respects all three.

Foundation Choices

  • Slab on grade with proper moisture barriers and a solid subgrade
  • Pier and beam to keep floors high in low spots or flood zones
  • Grade beams and piers near big trees to protect roots

We pick the right solution based on soil, flood maps, and access. Our goal is a level floor that stays solid for years. Learn more about our Foundation Construction.

Roof and Exterior

  • Roofs that drain fast with gutters that do not dump water on your neighbor
  • Reflective shingles or metal to reduce heat gain
  • Siding that matches your block, from smooth stucco to lap siding with the right reveal
  • Impact rated windows are not required for most of Houston, but good low E glass and tight seals are worth it

We also install Gutter Installation, Roofing Services, and Siding Services when your design calls for them.

Mechanical Electrical and Plumbing

  • Quiet mini split systems with zones, or a small conventional system if you prefer
  • Spray foam under the roof, or dense batt with proper ventilation
  • On demand water heaters that save space
  • LED lighting and smart controls that do not require an engineering degree to use

Layout That Lives Large

Small spaces need smart plans. We borrow tricks from modern apartments to make your ADU feel roomy.

  • Pocket doors where swings eat space
  • Taller windows for more light without losing wall space
  • Built ins for storage
  • Stackable washer dryer or shared laundry with lockout

We also match the look of your main house if that matters to your HOA or historic area. Craftsman trim for the Heights, classic brick accents for West U, clean lines for Montrose, and warm wood for Eastwood. Your ADU should look like it belongs.

Budget and Cost Drivers

Let’s talk money. ADU Construction has a wide range based on size, foundation, and finish level. We give a real budget for your lot during the free 3D quote. These items move the number up or down

  • Foundation type. Pier and beam or raised slab costs more than a basic slab. See our Foundation Construction.
  • Size and ceiling height. More square feet and taller ceilings add labor and materials.
  • Kitchen and bath count. More plumbing and cabinets add cost. Explore Kitchen Remodeling and Bathroom Remodeling.
  • Garage under the unit. Structure and stairs add cost but also add value.
  • Floodplain needs. Elevation, flood vents, and related details impact the budget. See guidance from FEMA.
  • Utility upgrades. New electrical service or long trench runs add cost.
  • Finish level. Quartz counters and custom tile look great. They cost more than stock choices.
  • Site access. Tight alleys and no staging space slow crews and add crane or delivery costs.
  • HOA or historic review. Extra drawings and slower approvals add time and soft costs. Ask about our Architectural Services.

We do not play games with allowances. Your 3D quote shows item costs so you can pick where to invest and where to save. Want that tile you saw on Instagram? We will price it and show the impact.

Rental Use Value and Rules

Many owners ask about renting their ADU. Houston allows rentals in many areas, but deed restrictions and HOAs can limit them. We review your documents early so you do not waste time. If long term rental is allowed, think about

  • Separate address and access. Alley stairs work well in many inner loop areas.
  • Sound control. Better insulation and solid doors keep tenants happy.
  • Durable finishes. Tile and quartz handle renters. Light colors help with turnovers.
  • Parking. Plan for at least one off street spot if your block is tight.

Rents change by area. Heights garage apartments near 19th Street rent higher than spots far from transit. Near the Texas Medical Center and Rice, units often stay occupied by students and staff. Near Energy Corridor, traveling professionals look for short leases. We can weigh rent against build cost to help you think through payback. We do not list or manage rentals, but we can refer property managers who do.

Utilities and Site Services

ADUs need the same level of utility planning as a small home. Here is how we handle it

  • Water and sewer. We tap to the main house lines where allowed or run new lines if needed. We keep slopes and cleanouts code compliant. We avoid big tree roots.
  • Gas. We check meter capacity and pipe size. We run new lines to the ADU or spec an electric package if you prefer.
  • Electric. We confirm service size. We add a subpanel in the ADU or set a new meter if you want separate billing.
  • Drainage. We keep water moving off the site with grading and gutters. If the added hardscape triggers detention needs, we add the right system with civil input.
  • Internet. We run conduit for data so your tenant or guest does not steal your Wi-Fi from the patio.

We plan trench routes to avoid your garden and your dog’s favorite spot. We also call in line locates before we dig. Safety first.

Build Quality and Codes We Follow

Your ADU is a real home. It must meet current building codes. We build to Houston’s adopted codes and local amendments. That includes structure, energy, and life safety.

  • Framing that meets wind load for our region
  • Moisture control that fights Houston humidity
  • Insulation that keeps the unit comfortable and bills reasonable
  • Fire blocking and rated assemblies where required
  • Safe stairs, handrails, and guards
  • Smoke and CO detection in all the right spots

We document inspections and keep a clean site. A tidy job runs faster and makes better neighbors. Your trash bins still get out on pickup day. Your mailbox stays clear.

Houston Neighborhood Insight

We build ADUs across the metro. Here is how they often fit

  • The Heights, Woodland Heights, and Norhill. Alley garage apartments that match bungalow style. Lap siding and gable roofs fit well.
  • Montrose and Museum District. Modern studios over garages. Clean lines, metal accents, and smart glass work well.
  • West U and Southside Place. Traditional cottages with brick details and neat trim. Great for family use.
  • Garden Oaks and Oak Forest. Larger backyard cottages for long term rental or family.
  • Eastwood, East End, and EaDo. Flexible studios with modern finishes and creative outdoor space.
  • Meyerland and Braeswood. Elevated builds where needed, with durable finishes below.
  • Spring Branch. Deep lots allow detached units with driveway parking.

Every block is different. Deed restrictions matter more than the zip code. We help you read them and plan around them.

Small Details That Make a Big Difference

Great ADUs feel easy to live in. We obsess over small things so you do not have to.

  • Windows set for privacy from the main house
  • Good outdoor lighting for safe steps at night
  • Hose bibs placed where you actually need them
  • Quiet bath fans that you do not have to shout over
  • Tile grout colors that hide dirt but still look sharp
  • Door swings checked so they do not fight each other
  • Storage tucked under stairs or along hallways

These details are not flashy. They matter every day.

ADU Construction That Respects Your Yard and Neighbors

We keep the peace while we build.

  • Clear hours that match Houston rules
  • Clean fences and protected trees
  • Street parking plans so your block stays friendly
  • Jobsite signs with a phone number so neighbors can reach us
  • No loud radios or trash blowing down the street

Good projects improve more than a single lot. They make the block better.

Thinking About Energy and Comfort

Houston summers are hot and sticky. We plan for comfort and lower bills.

  • Right sized HVAC so you do not get short cycling
  • Ducts inside conditioned space where possible
  • Sealed attic or properly vented attic, based on your build
  • Low E windows with the right solar heat gain for your orientation
  • Shading from overhangs or trees where it helps
  • Smart thermostats that are easy to use

Quiet, cool, and efficient. That is the goal.

Safety Security and Access

If you plan to rent your ADU or use it for guests, think through access and safety.

  • Clear address markers and lighting at the entry
  • Keypad deadbolts that you can reprogram
  • Peephole or small sidelight for visibility
  • Fences and gates that secure the main yard
  • Driveway mirrors for alley exits if sight lines are tight
  • Fire extinguishers and escape windows where required

We include these in our plan set so nothing gets missed.

Materials That Handle Houston Weather

Humidity and storms are part of life here. We pick materials that last.

  • Exterior siding rated for our climate with the right fasteners
  • Corrosion resistant hardware where needed
  • Roofing with strong warranty support from major brands
  • Tile and waterproofing tested for wet areas
  • Flooring that can handle indoor humidity swings
  • Exterior doors and thresholds that shed water

Maintenance should be simple. Wipe it, wash it, or paint it when needed. No drama. Ask about our Roofing Services and Tile flooring installation.
