Do you need a building permit in Roman Forest, Texas?

Yes. Roman Forest requires city approval for new houses and garages, along with storage buildings, commercial buildings and alterations to existing structures1. The city's architect reviews the plans and a permit is issued if they are approved10. Every permit requires passing final inspections11.

This is a city rule. Montgomery County's permit department serves land outside city limits, so a lot inside Roman Forest does not go through the county permit counter for the house itself. The county's answer for unincorporated land is on the Montgomery County page.

Who issues building permits in Roman Forest?

The City of Roman Forest issues building permits and certificates of occupancy for lots inside city limits12. We could not load the city's website to confirm a current phone number or counter address, so call Roman Forest City Hall and ask for the building permit desk before you buy or design anything.

A new residence must be inspected and comply with the ICC Residential Building Code and the city's deed restrictions before anyone can occupy it2.

What land-use rules apply to a lot in Roman Forest?

Roman Forest regulates land use through a citywide land-use ordinance rather than a district map we could confirm. The ordinance sets a minimum exterior area of 1,600 square feet for dwellings, with separate minimums for 1½-story and two-story homes7. No building may sit between the recorded plat building line and the street, and none may be nearer than 10 feet to a side-street or interior lot line8.

On a residential lot, the ordinance allows a single-family residence plus servants' quarters, garages and similar structures, so a second dwelling or rental unit is not simply allowed12. We could not confirm minimum lot size, building height or lot coverage numbers, so ask City Hall.

Can you live in an RV or tent in Roman Forest?

No. Roman Forest's land-use ordinance makes it unlawful to move a trailer or tent onto a lot, and no such structure may serve as a temporary or permanent residence36. That rules out the common plan of parking an RV on the lot while you build. We could not confirm how the city treats manufactured homes, so ask City Hall before buying one.

How do septic permits work inside Roman Forest?

Septic in Roman Forest takes two permits: a building permit from the city and an on-site sewage facility permit from Montgomery County4. The county's Environmental Health Services acts as the local agent for the state's septic program13.

A licensed installer must do the work, and owners cannot install their own system5. The city also requires a yearly inspection of any septic system14. Where the city sewer is available, a private septic system is unlawful15. Soils matter too: only about 2.2% of Montgomery County soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system16.

Building a home in Roman Forest: the steps, in order

  1. Confirm with Roman Forest City Hall that the lot is inside city limits and ask about the deed restrictions that apply2.
  2. Check whether city sewer is available; if it is, a private septic system is not allowed15.
  3. Check the floodplain: a floodplain development permit is required inside city limits9.
  4. Submit two sets of standard architectural plans to the city; hand-drawn sketches are not accepted10.
  5. If you need septic, get the city building permit and the county permit from1317.
  6. Pass the city's inspections, then obtain the certificate of occupancy before moving in112.

What stays with Montgomery County, and what to check before you buy

Septic permits and inspections stay with Montgomery County Environmental Health Services4. For land outside Roman Forest, the county's unincorporated-area rules apply instead; see the Montgomery County page.

Countywide figures: Montgomery County's effective property tax rate is 1.6%18, and its typical home insurance premium is about $2,140 a year19. We could not confirm a city rule on private wells, so ask City Hall and the groundwater district before you plan one.

Watch-outs

  • We could not confirm a current phone number for Roman Forest's building permit desk, so call City Hall first and ask which office handles building permits1.
  • Living in an RV, trailer or tent on a Roman Forest lot is unlawful, even temporarily while you build3.
  • A septic system needs both a city building permit and a county septic permit, and a private septic system is unlawful where the city sewer is available415.
  • Roman Forest publishes a minimum dwelling size and setbacks78, but we could not confirm minimum lot size, building height, lot coverage, subdivision or agricultural rules, so ask City Hall before buying.
